The more important of these field researches carried on during 1919 are here described briefly, for the most part by the explorers themselves. Naturally the great war held in abeyance a number of proposed expeditions, some of which it has since been possible to send out on the resumption of a peace status. GEOLOGICAL EXPLORATION IN THE CANADIAN ROCKIES Geological explorations were continued in the Canadian Rocky Mountains during the field season of 1919 with two objects in view: (1) The discovery of an unmetamorphosed, undisturbed section of the Upper Cambrian formations north of the Canadian Pacific Railway ; and (2) the collection of fossils to determine the various formations and to correlate them with the Upper Cambrian forma- tions elsewhere. The party going from Washington consisted of Dr. and Mrs. Charles D. Walcott and Arthur Brown, who has accompanied them for a number of years. Early in July an attempt was made to reach Ghost River northeast of Banff, Alberta, but this failed owing to the extensive outbreak of forest fires in that region. In August the party proceeded north from Lake Louise over Bow Pass down the Mistaya Creek to the Saskatchewan River, and thence up to the head-waters of the Middle Fork in the area about Glacier Lake, where a wonderfully well preserved Upper Cambrian series of rocks was found that had been cut across in pre-glacial time by a deep east-and-west canyon valley, at the head of which were two beautiful glaciers, which are illustrated by the panoramic view figure I (Frontispiece), and more in detail by figures 5, 7, 8, 9, and ro.

The measured geological section begins at the foot of the ridge at the extreme left of figure 1, and was measured in the cliffs and slopes, and thus carried to the side of the Mons glacier shown in NOG I SMITHSONIAN EXPLORATIONS, IQIQ 3 the central portion of figure 1, the upper limit of the section being above the narrow vertical F-shaped snow bank directly over the glacier. The evenly bedded rocks sloped at an angle of from 10 to 20 degrees, westward, which accounts for the great thickness mea- sured, although the elevation above the canyon bed was not more than 3,500 feet. Fie. 3.—Walcott camp located in the brush beside Glacier River, 1 mile (1.6 km.) below the foot of Southeast Lyell Gacier, which 1s shown more distinctly in figure 5. Photograph by Mrs. C. D.

Figure 1 is a profile view of Lyell Glacier from the Continental Divide on the right to where it abuts against the low cliff on the left. In figure 6 the foot of the glacier is shown, along with large amounts of débris forming the terminal moraine, also the dark mass of broken rock and débris carried on the back of the glacier, which is shown in figures 1 and 6.

Walcott, 1910. Mons Glacier is named from Mons Peak, shown in figures 5 and 8. It flows over the high cliffs (see fig. 8), and creeping down the 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 slope, spreads out in a fan-like form toward its lower end. Seen in profile, this portion of the glacier resembles a great animal sliding down the sides of the broad canyon.

Fic. 8—View of Mons Peak (10,114’) and the upper snow fields of Mons Glacier, also the cascade of the glacier over the cliffs below. The summit of the peak is more than 2 miles (3.2 km.) back of the glacier, the intervening space being occupied by-a great snow field from which the glacier flows. The locality is about the same as for figures 2 and 5. Photograph by Mr. and Mrs. C. D. Walcott, 1919. These views (figs. 5, 8, 9, 10 and 11) illustrate a glacier from its néve at the base of Mons Peak (fig. 8) to its foot (fig. 11), where the retreating ice is making its stand against the force of the summer sun and wind.

One of the views across Bow Valley is of Mount Ball (fig. 14), which is one of the massive peaks on the Continental Divide where the Middle Cambrian rocks have a great development. The preliminary study of the fossils in the several formations cor- relates them with the Upper Cambrian formations of Wisconsin and Minnesota and the Upper Cambrian section in southern Idaho, and to amore limited extent with that of the central belt of Pennsylvania. GEOLOGICAL AND PALEONTOLOGICAL EXPLORATIONS AND ; RESEARCHES Field-work in the Department of Geology has been considerably restricted by prevailing conditions during the season of 1919. Research work has, however, continued on the collections accumu- lated either in years past or obtained through gift or purchase in more recent times. One of the most interesting acquisitions to the geological col- lections during the year 1919, was some 15 kilograms of the meteoric stone which fell at Cumberland Falls, Kentucky, in April of this year. The stone, which proved to be a coarse breccia of enstatite fragments and a dark chondritic stone, has been studied by Dr. Mer- rill, and a paper giving his results is now in press. Owing to the fact that the division of Mineralogy has been without a head for two years, a large amount of work upon the collections has been necessary and hence only a limited amount of field and research work was possible. On his own initiative, two field trips were under- taken by Assistant Curator Foshag, one to the mica mines about Amelia, Virginia, where a considerable amount of study material was collected. This included a large number of specimens of the rare mineral microlite and an exhibition specimen of manganotantalite, the latter species not before represented in the Museum’s exhibition series. The old iron mine at Brewster, N. Y., was also visited and some material for study collected. The work of the division in the Museum’s laboratory consisted in an investigation of the hydro- talcite minerals, resulting in the establishment of the true chemical nature of this group. Shorter researches on miscellaneous minerals NO. I SMITHSONIAN EXPLORATIONS, I919 7 were also carried on. Work is now under way on the study of the mineralogy of serpentine and its relation to the chlorite group, and also the correlation of the chemical composition and the optical properties of rhodonite, the latter in collaboration with Dr. E. S. Larsen of the U. S. Geological Survey. In October various localities in Connecticut were visited by Assistant Curator Earl V. Shannon, including the vicinity of Long Hill in Trumbull, where tungsten has been mined in years past. Extensive collections comprising much interesting material were Fic. 17.—Transporting fossil specimens in Southeastern Indiana. Photograph by Bassler. obtained which will be studied and described. The trap quarries of Meriden, Conn., were also visited and extensive collections of the zeolites and other secondary minerals secured. The pegmatite locali- ties of Collin’s Hill in Portland ; the workings of the old cobalt mine and the old lithia mine in Chatham, and a number of feldspar quar- ries in this region were visited and collections of the representative minerals secured. Much of the material collected as above has been carefully examined and descriptions will appear in forthcoming num- bers of the Proceedings. 3 18 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Explorations for paleontological material were limited during 1919 to two short field trips by Dr. R. S. Bassler, Curator of Paleon- tology, who continued the work of former years in securing certain large showy specimens of fossils and rocks required for the exhibi- tion series. Dr. Bassler spent a portion of June in southeastern Indiana, first proceeding to the locality where at the end of the field season of 1918 he had cached for safe keeping, because of inability to secure help in getting them to a freight station, several large exhibition slabs crowded with brachiopod shells. These slabs were Fic. 18.—Fossiliferous strata of the Richmond formation in south- eastern Indiana. The slab indicated is now on exhibition at the National Museum. Photograph by Bassler. found undisturbed, but transportation conditions proved equally bad as in the summer before and it became necessary to employ the primitive method shown in figure 17. By the use of burlap covering and an abundant supply of weeds for padding, each slab was finally slid along the rails for a considerable distance to the nearest station. The same area in Indiana, namely, the vicinity of Weisburg where the early Silurian rocks are well exposed, was then explored tor fur- ther desirable exhibition specimens. Water worn slabs crowded with animal and seaweed remains are abundant in all the creeks of NOS 4 SMITHSONIAN EXPLORATIONS, IQIQ IQ this richly fossiliferous region, but large rock specimens with their surfaces unweathered are comparatively rare. Fortunately for the present purposes, heavy freshets in the spring of 1919 had uncovered the richly fossiliferous layers along the creek shown in figure 18, and here several additional well-preserved exhibition slabs were secured and transported to the freight station by the rail route mentioned be- fore. One of these specimens, a slab several feet in length and width, is worthy of special mention, as its surface 1s crowded with impres- sions of the branching fossil seaweed Buthotrephis, and with excel- lent examples of the dumbbell seaweed Arthraria. The discovery of this specimen was most fortunate as a large slab containing an assemblage of these ancient plant remains has long been needed for the exhibition series of fossil plants. In October, 1919, Dr. Bassler was detailed to proceed to Dayton, Ohio, in order to prepare for shipment to the Museum the largest entire American trilobite so far discovered. This unique specimen (fig. 19) was discovered in the Richmond formation in the excava- tions for the Huffman Conservancy Dam 6 miles east of Dayton, which forms a part of the greatest engineering project ever under- taken for controlling stream flow, with the exception of the Assouan Dam along the Nile. Following the destructive floods in the Miami valley in 1913, the Miami Conservancy District was organized to prevent a repetition of this disaster through the control of the Miami River and its tributaries by dams extending entirely across their valleys. This operation involving an expense of over fifteen million dollars has been under way for three years, and will require three years more for its completion. The view (fig. 20) showing the excavations in which the trilobite was found illustrates only the beginning of one of these dams. This particular dam when com- pleted, will extend a distance of a mile entirely across the river valley. Normally the water will flow in its usual channel, but in flood times it will be retained and allowed to escape gradually. The trilobite which was found lying on its back in a hard clay bed in the central part of the excavation was unearthed by the pick of a workman, who believed it to be a petrified turtle. Mr. Arthur E. Morgan, Chief Engineer of the Miami Conservancy District, recog- nized the true nature and scientific value of the so-called turtle and presented it to the Smithsonian Institution, where it now forms a most instructive and unique exhibit in the hall of invertebrate paleontology. The value of the specimen is further increased by the fact that it has become the type of the new species /sotelus brachy- cephalus described by Dr. August F. Foerste of Dayton, Ohio. 20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 During the summer of 1919, Mr. Frank Springer resumed his field researches upon the fossil echinoderms of the Ohio Valley, which had been interrupted by the war, with the special object of securing additional material from the remarkable crinoidal fauna of the Laurel formation of the Niagaran for use in his monograph on the Silurian crinoids. The principal work was done at St. Paul, Fic. 19.—The type specimen of /sotelus brachycephalus Foerste, the largest known entire American trilobite. About % natural size.

Collecting in the beds at this locality is laborious and difficult, and specimens are not abundant, but they exhibit in some respects a strong paral- lelism with those of the Swedish and English Silurian, which renders NO. I SMITHSONIAN EXPLORATIONS, I9QIQ 21 their comparative study one of much interest. Important new mate- rial was obtained which is added to the collection of echinoderms deposited in the National Museum. Mr. Springer’s monograph of the Crinoidea Flexibilia, now being published by the Smithsonian Institution, has been printed and only awaits binding to be ready for distribution. It will be in two quarto volumes, one of them con- taining 79 plates. The Section of Vertebrate Paleontology has been unable to under- take any field explorations during the past year, and the time of the staff has been largely employed in preparing and mounting for exhibition material otherwise obtained. | Fic. 20——View of small portion of Huffman Conservancy dam near _ Dayton, Ohio, showing excavation in which the largest trilobite was found. Photograph by courtesy of Arthur E. Morgan, chief engineer. Through the acquisition from the veteran collector of fossils, Mr. Charles H. Sternberg, of an excellent skeleton of the large swimming lizard 7'ylosaurus dyspelor and a skull of the primitive horned dinosaur Monoclonius, an interesting addition to the exhibi- tion collection was made. Figure 21 shows the 7ylosaurus skeleton in process of being mounted for exhibition by Mr. N. H. Boss. It will form a panel, in half relief, and will occupy the wall space in the northeastern part of the main exhibition hall of fossil vertebrates. The diving pose given the skeleton was largely determined by the position of the articulated tail as found in the ground. 22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Tylosaurus was a long, slender-bodied reptile some 25 feet in length, having the limbs modified into short swimming paddles, with a long, powerful, compressed tail. It was predatory in habits, living on fishes and probably also on the smaller individuals of its own kind. One of the unique features of the skeletal structure 1s the presence near the middle of the lower jaw of a joint which permits it to bow outward. This feature in connection with the loose articulation at the extremities allowed the jaws to expand and thus enabled the Fic. 21—The swimming reptile 7ylosaurus dyspelor in process of preparation for exhibition.

Gilmore, and the results of his investigations will be pub- lished in the Proceedings of the U. S. National Museum. In figure 22 is shown another of the recently mounted skeletons— that of the large extinct Rhinoceros-like mammal from the Tertiary (Oligocene) deposits of western Nebraska, named by Osborn Bron- totherium hatcheri. The bones of this skeleton were found em- NOr I SMITHSONIAN EXPLORATIONS, IQT9 23 bedded in a fine sandstone. An idea of the amount of painstaking work involved in the collection, preparation and mounting of such a large fossil skeleton may be gained by the fact that after the bones were collected and freed from the enclosing sandstone, 258 working days were spent in restoring the missing parts, posing the skeleton and making and fitting the supporting iron work. The National Museum has now the distinction of having the larg- est existing collection of Titanothere remains. The specimens were Fic. 22—The Rhinoceros-like mammal Brontotherium hatcheri mounted in the laboratory of vertebrate paleontology. Photograph by Bassler. brought together by the late J. B. Hatcher, working under the direc- tion of Prof. O. C. Marsh, at that time United States Paleontologist, and it is peculiarly fitting that the only skeleton complete enough for mounting should pertain to the species named 1n his honor. Among other important investigations in the mammalian division of the year is a study by Mr. Gidley of the Peccaries of the Cumber- land Cave deposit. This includes the description of three new species, the redefinition of the Pleistocene species hitherto described. 24 SMITHSONIAN MISCELLANEOUS COLLECTIONS Wks W/Z and the partial revision of the entire peccary family (Tayassuidae), the latter involving redefinitions of the two living genera of this group, and of the two suilline families Suidae and Tayassuidae. An important outcome of this preliminary investigation has been to emphasize the fact that the entire group, and especially the Pleisto- cene species of American suillines, is in need of thorough revision. EXPEDITION TO SOUTH AMERICA IN THE INTERESTS OF THE ASLROPHYVSICAE OBSERV ALOR Dr. and Mrs. C. G. Abbot sailed from New York on May 2, by way of the Panama Canal to Antofagasta, Chile. The expedition had three objects. First, to observe the total eclipse of the sun of May 29 at La Paz, Bolivia; second, to enable Dr. Abbot to confer with the officials of the Argentine Weather Bureau in relation to the use of the observations of the solar radiation for the purpose of forecasting weather conditions; third, in order that a visit might be paid at the observing station of the Smithsonian Institution at Calama, Chile, which is maintained by the Hodgkins Fund under the direction of Mr. A. F. Moore and assisted by Mr. L. H. Abbot. Landing at Antofagasta, the journey was continued by the English railroad up into Bolivia over that desert which Darwin describes in his “ Voyage of the Beagle.”’ Although the travelers had visited the Sahara Desert in southern Algeria, and the deserts of the southwest of the United States, there was still reserved for them a stronger impression of a void wilderness in the Nitrate Desert of Chile. Neither bird, beast, insect nor crawling thing, nor any vegetation could be seen as far as the eye could reach. Stopping a day at the observing station at Calama, in order to repack the apparatus required for the eclipse expedition, and joined by Mr. A. F. Moore, director of the observing station, they went on to La Paz. The plateau of Bolivia is eminently the country of mirage. The railroad appeared to rise out of a lake and to run inte a lake at no distant point beyond, and all of the mountains appeared to be islands rising out of the lake. The desolation, while not equal to that of the Nitrate Desert of Chile, was yet very marked. Near La Paz the country becomes cultivated with fields of grain and vegetables, and villages of people are passed by on either side. The mountains take on a new grandeur, especially the great mountain Illimani, which rises to a height of 22,000 feet or more. However one may have been impressed with the grandeur of the mountains, he is unprepared for the view of the great canyon in NO. I SMITHSONIAN EXPLORATIONS, I9QIQ 25 which La Paz lies. In most respects it is comparable with the Grand Canyon in Arizona, but with several added charms. First of all, on the farther side lies the great chain of the Andes, to which [llimani belongs, snow-covered although so far within the tropics, while on the nearer slope of the canyon all is green with vegetation, trickling Fic. 23.—Total solar eclipse of May 29, 1919. brooks running down, and the beautiful city lies upon its cluster of hills all surrounded by the colors and broken features which might result by combining the Grand Canyon of the Colorado with the Garden of the Gods near Colorado Springs. By the kind assistance of the manager of the English railroad the eclipse station was located at El Alto, situated on the rim of the 26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 canyon at about 14,000 feet elevation. There the apparatus was set up, and on the day of the eclipse very satisfactory observations were made, both photographs of the phenomenon and measurements of the brightness of the sky and the nocturnal radiation. The accom- panying photograph shows in but a feeble way how splendid was the eclipse phenomenon on this occasion. ‘The corona extended at least two diameters of the sun in almost all directions, with a great pro- fusion of fine streamers. Underneath the sun, that is to say towards the east, there hung a sickle-shaped solar prominence of hydrogen and calcium gases, extending fully 150,000 miles outwards from the sun and over 300,000 miles long, which cast its crimson glory over all. The background against which this splendid phenomenon was seen was a range of mountains, perhaps 50 miles distant, which raised their snow-covered heads fully 20,000 feet in altitude. From La Paz, Messrs. Abbot and Moore proceeded at once to La Quiaca, Argentina, where they inspected the meteorological observatory and conferred with Messrs. Wiggin and Clayton, Chief and Chief Forecaster, respectively, of the Argentine Meteorological Service. Under Mr. Clayton’s direction a system of forecasting by the aid of daily telegraphic reports of the intensity of the radiation of the sun as observed at Calama, Chile, has been worked out with encouraging success. Both Mr. Wiggin and Mr. Clayton were firmly convinced of the great value of solar radiation observations for forecasting. Arrange- ments were tentatively entered into for the transfer of the Smith- sonian observing station at Calama to the Argentine Government, to be located at La Quiaca thereafter. At the present time, however, these arrangements have not yet been completed by the higher officials of the Government of Argentina. From La Quiaca the travelers returned to the observing station at Calama, Chile, where Dr. and Mrs. Abbot remained about a month before returning to the United States, during which time Dr. Abbot worked over the results obtained with a view to discovering some means of measuring the intensity of the solar radiation without the long and tedious process of observing and computing which has hitherto been necessary. In this he was so fortunate as to discover, with the aid of Mr. Moore, a method by means of which suitable observations taken within a period of 10 minutes may be reduced within a period of 2 or 3 hours. Thus the intensity of the solar radiation outside the atmosphere may be determined with greater accuracy than by the former method which required about 3 hours of observing and about 15 hours of computing.

AUSTRALIAN EXPEDITION The zoological work by Mr. H. C. Raven in Borneo and Celebes, which has been made possible through the generosity of Dr. William L. Abbott, came to an end in 1918, as explained in the last Explora- Fic. 28—A pair of adult duck- bills, the male (at left) showing the spurs on hind feet. tion Report (p. 35). At the close of the war Mr. Raven did not wish to return immediately to the field. Doctor Abbott therefore arranged to send Mr. Charles M. Hoy to Australia for the purpose of collect- ing vertebrates, especially those which are in danger of extermina- tion. From the point of view of the national collection of mammals there is probably no field-work of similar scope that could approach this in importance. The fact has long been recognized, but the means for putting such a project into execution have hitherto been NO. I SMITHSONIAN EXPLORATIONS, IQIQ 29 lacking. The remarkable Australian mammal fauna is now repre- sented in the museum by only about 200 specimens. Very few of these have been collected in accordance with present-day methods, and no species is represented by adequate series of adults and young, of skeletons and material in alcohol. Not only is this true of our collection, but it is equally true as regards other museums in America. So many of the Australian mammals are now rapidly approaching extermination that in future there will be few oppor- tunities for securing the material needed for a proper representation of the fauna. Mr. Hoy spent about two months in Washington assembling his outfit and preparing for his trip. He left for San Francisco early in Fic. 29.—Two young duck-bills in their nest. May and arrived in Sydney about the end of the month. The period from June to November has been passed at various localities in New South Wales. While no specimens have yet been received (December 31, 1919), it is evident that the work has been very suc- cessful. The following passages from Mr. Hoy’s letters and reports will give an idea of the conditions under which it has been car- ried on: “Travel is rather difficult just now. Each state has its own quarantine restrictions, on account of the ‘flu’ and it is quite difficult to get from one to the other. Then too a seaman’s strike is on, making travel by boat very uncertain. The railroads are run by the state governments and each state has a different gauge road and different rates. “T have a great chance to get Platypus (duck-bill). A Mr. Burrell, whose hobby is Platypus is going after them on the first of October. As he has 30 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 kindly offered to take me with him and is only interested in the-natural history, it will be a great chance for me to get not only the adults but also the young and possibly an egg. Mr. Burrell is after their nesting habits and is taking men along to dig out the burrows. It is safe to say that there is not another man who knows as much as he about the duck-bill. “Nine weeks were spent in the Wandandian region (19 miles S. W. of Norwra, N. S. W.) with the result of but one hundred and thirty one (131) mammals, and one hundred and twenty-four (124) birds collected. Among the mammals ten genera and twelve species are represented in my collection. “The greatest agent working toward the extermination of the native animals is the fox, next comes the cattle and sheep men who distribute poison by the Fic. 30.—An Australian marsupial with parachute membrane like that of the flying squirrel. cartload in the effort to reduce the rabbits. This has also caused or helped to cause the extermination of some of the ground inhabiting birds. Another great agent is the bush fires which sweep over the country. These are often lit intentionally in order to clear out the undergrowth and thus increase the grass. “ Owing to the great increase in the price of rabbit skins and the consequent increase in trappers the rabbits are fast ceasing to be a pest, and in some sections have become quite scarce. ‘The foxes, which are everywhere nu- merous, after killing off the native mammals are now turning to the rabbits, which also helps in their reduction. The extermination of the native mam- mals has apparently gone much farther than is generally thought. Many species that were plentiful only a few years ago are now almost, if not alto- NO. I SMITHSONIAN EXPLORATIONS, IQIQ 31 gether, extinct. Diseases have also played a great part in the extermination. The native bear died in thousands from a disease which produced a great bony growth on their heads. A mysterious disease also spread through the ranks of the native cat, Dasyurus viverrinus; the domestic cat also played a great part in their extermination. Even adult specimens of Dasyurus were often dragged in by the family cat. “The only mammals caught in traps were Mus assimilis and Phascologale flavipes. The others were all shot or snared.

The hunting of kangaroos and wallabies was greatly handicapped through the lack of a rifle. “ Perameles nasuta has been practically exterminated throughout N. S. W., but they are still to be found in Mosman, one of Sydney’s suburbs, so I made a trip out there and was able to get a fine female with two young in her pouch. This was trapped inside the Taronga Park Zoo grounds with the kind per- mission of Mr. A. S. Le Souéf. “The fact of Perameles nasuta being found at Mosman is probably due to the isolation of that district from the rest of N. S. W. by the city of Sydney, thus keeping out the introduced foxes. 32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 “The country at Bulliac is a good example of what the cattle men will do in a few years time in killing off and burning the timber and the consequent destruction of animal life. Five years ago Bulliac was a virgin forest but then the railroad was built and now it is devoid of living trees for miles on each side of the track except for small and scattered patches in the more inaccessible gullies which form the last resort of the fast disappearing mam- mals. There are very few game laws in Australia and no one gives any attention to the ones that are in order. The Bulliac trip has clearly shown that the edge of the settlements, and even a short way into the wilds, is no better than the older settled parts and in order to get results one must go into the wilds. It is the killing and burning of the brush, by the cattle men, that does the most to kill off the animals, and they are yearly reaching farther and farther away from the railroads. One thing that was very noticeable was the great abundance of the introduced rats. They seem to have driven out or killed off practically all the native rats and I found them everywhere. Fic. 32—Skinning a kangaroo. “A trip was made primarily for the eggs and young of the Platypus. Fifty miles of bank was searched and approximately one hundred burrows were dug out only six of which contained young. These six burrows furnished eleven young of which Mr. Harry Burrell, of Sydney, with whom the trip was made, secured 7 while I secured 4. The intense drought which has scarcely been broken for over twelve months (it is the worst since 1862) has advanced the breeding of the animals somewhat so we were too late for eggs. The Platypus although scarce is not by any means nearing extinction and if they continue to be protected there is every hope that they will never become extinct. Young Hydromys were also looked for but the drought seems to have interfered with their breeding and but two embryos were obtained. The adults themselves were very scarce and but six specimens were obtained. The accompanying photographs show some of the characteristic Australian mammals obtained by Mr. Hoy. G. S.

L. Abbott continued his investigations at the eastern end of the Island of Haiti, making two visits during the year 1919. His first visit was to the Samana Bay region and to the mountains in the vicinity of Sanchez and Constanza, and covered the interval from February to June. On his second trip (July to October) he stopped at Sosua, on the north side of the island, where he made a search for certain birds needed to fill gaps in the material already collected : thence to the Samana Peninsula, after which he went to the islets Saona and Catalina, off the southeastern corner of Santo Domingo. Before returning to Philadelphia, he spent a few days at Lake Fnri- quillo, where he secured a few water birds of interest. The material gathered on these two trips was varied in character, embracing the several groups of vertebrates, as well as mollusks, insects, and plants, with a plentiful series of archeological objects from caves in the Samana district. Of birds alone, he obtained 27 study skins, 87 alcoholics and skeletons, and 56 eggs. Four species of birds in this collection represented forms not hitherto possessed by the Museum, and three or four other species were not previously known to occur on the island. Probably the most noteworthy objects in the bird collection were four eggs of the Dulus dominicus, known variously as the Sigura, Palm Slave, or Palm Chat, a bird somewhat larger than an English Sparrow, of sombre colors, but structurally different enough from other birds to occupy a family by itself. It ““apart- ment house” nests are sufficiently noticeable to attract the attention is common and noisy, and lives in colonies, and its enormous of the most casual person. The discovery of the Palm Chat was almost coincident with that of America, for Columbus and his men must have seen these birds and their nests when a landing was made on this island at the end of 1492. Oviedo, the official historian of the Indes, early made its acquaintance, and devoted a chapter to it in his ‘‘ Hystoria natural y general de las Indias yslas,” published in 1535. The Sigura was thus one of the earliest, and at that time one of the best-known birds of the new continent. Various authors of later date have described the bird, its habits and nests, but thus far, apparently no correct description of the eggs has been given, although a French writer, in 1851, reported them to be white and unmarked. The eggs sent by Dr. Abbott are authentic, and will be described in detail elsewhere, but the illustration here given (fig. 35) will convey a general idea of their appearance, and it may be remarked NO. I SMITHSONIAN EXPLORATIONS, IQIQ ios) oni that the eggs are rather large for the size of the bird, measuring, roughly, about one inch by three-quarters of an inch in diameter. The description of the nest, as furnished to Dr. Abbott by the man who made the actual examination, indicates a radical departure from other known types of birds’ nests, but a careful study of the interior of the mass by a competent observer will be required before the strange arrangement of the individual nests can be considered as accurately known. Dr. Abbott writes: “ The communal nest was Fic. 35—Eges of the Palm Chat (Dulus dominicus). built in a small royal palm, about 25 feet from the ground. The nest was about 44 feet in diameter, and about the same in height. Built of a loose mass of sticks from I to 2 feet long, about the thickness of bone knitting needles. There appeared to be but one entrance, from above.. A local man (John King) climbed the tree and gave me the description of the iternal construction of the nest. The entrance passage was narrow and crooked and led into a large central chamber about the size of a small bucket. The nests were placed around this on shelves of softer materials (fine bark, etc.). All four eggs were in one nest. The other five nests were still empty. 36 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 ‘Tt is difficult to get into these nests, the huge smooth palm trunk (2 feet in diameter) must be climbed, and then it is difficult to crawl over the huge mass of sticks which lie interlaced amongst the crown of leaf stalks. “Most of the nests are in far larger palms than this one, and the nests are frequently much larger in size, and probably contain much larger colonies.” Fic. 36.—Dense forest of giant cedar (Thuya plicata) near Lake McDonald, Glacier National Park. BOTANICAL EXPLORATION IN GLACIER NATIONAL PARK MONTANA Mr. Paul C. Standley, assistant curator in the division of plants, spent the summer of 1919 in Glacier National Park, Montana, under the authority of the National Park Service, for the purpose of study- No. I SMITHSONIAN EXPLORATIONS, IQIQ Sy7. ing the vegetation of the region. The information thus obtained is to serve as the basis of a popular account of the plants to be published by the National Park Service, and it is expected that a complete and more technical account of the flora will be published by the National Museum. All the portions of the Park usually seen by tourists were explored, and 4,000 specimens of flowering plants and ferns were obtained, representing over 900 species. Aside from the scenic features of Glacier Park, one of its chief attractions is found in the plant life. Especially striking is the-dis- play of flowers above or near timber line, where the meadows are solid masses of brilliant color, formed by Indian paint-brushes, Fic. 37—Bearerass, Glacier National Park. monkey-flowers, fleabane, asters, harebells, heather, larkspur, gen- tians, fireweed, columbine, and a host of other plants. The most characteristic plant, perhaps, is the beargrass (Xerophyllum tenax, fig. 37), which occurs abundantly at middle altitudes and in alpine meadows. It is usually about 3 feet high and bears enormous plume- like racemes of creamy-white flowers. The narrow, tough leaves were used by the northwestern Indians in making baskets, hence the name of Indian basket-grass which is sometimes applied to the plant. The Continental Divide, which traverses the Park, has a marked influence upon plant distribution. On the east slope, whose drainage is partly into the Missouri River and partly into Hudson Bay, the flora is of the Rocky Mountain type, like that of Wyoming and Colo- 38 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Fic. 38.—Sperry Glacier, Glacier National Park.

The Transition Zone is indicated on the west slope by small areas of yellow pine timber, and east of the Park are the prairies of the Blackfoot Indian Reservation, which extend also within the Park boundaries along the stream valleys. The plants here are chiefly herbs, with a few shrubs, and they belong mostly to species which have a wide distribution over the Great Plains. by far the largest portion of the Park is covered with the characteristic vegetation of the Canadian Zone, which is the heavily forested area. Above the Canadian Zone, around timber line (6,000 to 7,500 feet), lies a narrow belt belonging to the Hudsonian Zone. The trees here are mostly low and stunted, and their branches frequently lie pros- trate upon the ground. Above this belt, and occupying the highest, exposed slopes, lies the Arctic-Alpine Zone, whose vegetation is composed chiefly of small herbaceous plants, with a few dwarfed shrubs, mostly willows. Many of the species of this zone are widely distributed in alpine or arctic regions of North America, and some of them occur also in similar situations in Europe and Asia. EXPLORATIONS AND CERION STUDIES ON THE FLORIDA KEYS Dr. Paul Bartsch, curator of marine invertebrates, U. S. National Museum, joined Dr. Alfred G. Mayer, the Director of the Tortugas Marine Biological Laboratory, of the Carnegie Institution, in New York on December 28, when they sailed south for Key West to make an examination of the Cerion colonies discussed in previous Smithsonian exploration pamphlets. The breeding experiments presented an entirely new phase, in the crossing, on one of the keys, of the native species, Cerion incanum (Binney) with one of the introduced Bahama species, Cerion viaregis Bartsch. It was this discovery that made it desirable to start an entirely new set of experi- ments. Furthermore, the anatomical differences discovered in the dissections of Cerions also made it desirable to gain material from all the colonies now existing on the Florida Keys, in order that these might be subjected to anatomization, to determine if Certon incanum is really one species, or a complex, shell characters alone being insufficient to determine this point. It was for this double reason that a return was made to Florida on May 2, and an exploration of the keys adjacent to Miami at once undertaken. On the 3d Capt. Tracy and Dr. Bartsch started in the “ Darwin,” a shallow draught launch of the Carnegie Institution, for an explora- tion of the shores of the mainland of the lower peninsula and the 42 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 outside keys. This was rendered comparatively easy, since they were fortunate enough to find the mosquito pests practically absent. Between May 3 and 6 they examined every sandspit on the mainland along Key Biscayne Bay, Card Sound, Little Card Sound and Barnes Sound. They then turned the southern portion of Barnes Sound and came up along the outer keys, examining them in turn. They crossed Key Largo at several places and walked long stretches in its interior. No Cerions were found on the mainland between Miami and the point where the railroad enters the keys, but two colonies were dis- Fic. 42.—Nest of swallow-tailed kite (Elanoides forficatus forficatus) between Flamingo and Coot Bay, Cape Sable, Florida. covered on keys a very short distance from the mainland in Barnes Sound.

No Cerion colonies were discovered on the keys forming the eastern perimeter of Barnes Sound, Little Card Sound, Card Sound and Key Biscayne Sound, excepting Porgee Key, where a goodly quantity were obtained, some of which have been dissected and published upon in the bulletin on “ Experiments in the Breeding of Cerions”’ recently issued by the Carnegie Institution. In addition to Cerions, collections of all the other species of land mollusks available were made wherever found at NO.

What is said for Liguus also applies to the equally large, though less brilliantly colored Oxystyla. On the 7th the ** Anton Dohrn ” left Miami for Indian Key, spend- ing the night off Rodriguez Key, and reaching Indian Key early on the following day. By to o’clock Capt.

They skirted the outside of the Lower Matecumbe Key, passed through the viaduct and then headed across the extensive flats of Florida Bay. The first stop was made on Sands Key, where a burned out colony of Cerions and a well flourishing colony of Oxystyla and Liguus were found. The expedition next headed for Flamingo City, which was reached at sundown. On May 9 they explored the region about Flamingo City and the coast for several miles to the east, for Cerions, and other mollusks. Cerions were not found, but large numbers of beautiful Liguus and Oxystylas were noted everywhere. A trip was then made by wagon to Coot Bay. 44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Coot Bay is a fine sheet of water fringed by tall mangroves, show- ing even at this season a sprinkling of water fowl. The evaporation from the lake at night undoubtedly keeps the adjacent region sup- plied with moisture, and is responsible for the large number of epi- phytic plants which render the region a veritable hanging garden. Orchids and tilandsias fairly draped and seemed to almost smother the trees and shrubs. Here we saw quite a number of rare birds, and among them the swallow-tailed kite, of which no less than six specimens were observed in the air at one time.

On the evening of the 1oth the party headed for Indian Key, stop- ping again at Sands Key, where they found a most remarkable flight of Florida yellow throats. Every tree and every shrub seemed to have on every branch one or more of these little fellows.

A colony was discovered likewise on the third key southwest of Big Pine Key. The fourth key is a mere clump of mangroves and did not contain Cerions. On the fifth key southwest of Big Pine Key a colony had been planted in 1912, and it is here that the crossing between the native and Bahama species has 46 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 taken place. On the sixth key no Cerions were found, but there was secured the new clapper rail which has since been described as Rallus longirostris helius, by Dr. Oberholser. Here, also, the pictures of the Ward’s heron (Ardea herodias wardi) nest and young were taken. This key might really be called Rail Key. In the seventh no Cerions were found, but the great white heron (Ardea occidentalis) was found breeding, and it was here that we secured our photographs of this bird and the specimen, which was shipped to the Zoological Park at Washington by parcel post from Key West. It is believed that this is the first time this species Fic. 46.—Young great white heron (Ardea occidentalis) in the nest in a mangrove thicket. has been shown in any zoological garden. The eighth and last key is a mere clump of mangroves without Cerion possibilities. On the evening of the 12th the expedition headed for Key West. A large collection of Cerions was made near the Bureau of [Fisheries station, to be used for breeding purposes at the Tortugas. A new set of experiments was started on Loggerhead Key, Yor- tugas. Ninety cages of bronze wire, 2’ x 3’ x 3’ high, were con- structed in which were placed one specimen each of two species. In addition to this nine cages 6’ x 8’ x 2’ high were built, in which 50 each of the two species were placed. On the 19th opportunity presented itself to return to Key West on a submarine chaser. MO, SMITHSONIAN EXPLORATIONS, 1919 47 A summary of the results so far obtained from the breeding experiments has recently been published as a bulletin by the Carnegie Institution. The results are rather startling, and incline one, con- trary to the views previously held by most people, to the belief that Cerions are not easily influenced, if at all, by environmental factors. The cross obtained in the Newfound Harbor colony opens up an entirely new vista in the problem of speciation, and it was this which was responsible for the starting of the new set of breeding experiments. Incidental to these investigations, which have been conducted since 1912, a list of the birds observed on the various keys has been kept and published annually in the Year Book of the Carnegie Institution. FIELD WORK ON THE MESA VERDE NATIONAL PARK, COLORADO The field-work of Dr. J. Walter Fewkes, Chief of the Bureau of American Ethnology, at the Mesa Verde National Park, in the sum- mer of 1919, was devoted to the excavation and repair of the pic- turesque cliff dwelling, Square Tower House, known for many years as Peabody House, and two low prehistoric mounds situated among the cedars on top of the plateau. - This work was a continuation of that of previous years and was carried on in cooperation with the National Park Service of the Department of the Interior. As Square Tower House has several unique structural features, the summer’s work has added to the educational attractions of the Park. At least two new types of hitherto unknown small-house ruins were dis- covered, and it is believed that a new page has been added to the history of the Mesa Verde cliff people. Dr. Fewkes was assisted in his field-work by Mr. Ralph Linton, a temporary assistant, who con- tributed much to the success of the work. The main object was to gather data that may aid one to better com- prehend the Indian civilization that arose, flourished on the Mesa Verde, and disappeared from the plateau over four centuries ago. Square Tower House is situated in a shallow cave at the head of a spur of Navaho Canyon opposite Echo Cliff, about 2 miles south of Spruce Tree Camp. It has long been considered by tourists one of the most attractive cliff dwellings of the park, but its inaccessibility has deterred all but the most venturesome from descending to it from the rim of the canyon. Part of the old Indian trail (fig. 47) was indi- cated by shallow foot holes cut in the almost perpendicular cliffs, and previous to the past summer this was the only means of access. 48 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Without mutilating the vestiges of this primitive trail another was made in the cliff near it, around which was constructed a balustrade (fig. 48), with ladders conveniently set to aid those who wish to visit the ruin.

THE MOSSES OF THE DUMMER-MACLENNAN EXPEDITION TO MOUNT ELGON, 1918 Several sets of the mosses collected on this recent expedition to Mount Elgon have been issued. I have received part of one through Mr. T. R. Sim, of Maritzburg ; and I have also had through my hands the sets belonging to the U. S. National Museum and to the Kew Herbarium. The material in many cases is poor, but in others it is good; and though the whole collection is not large, consisting of about 50 numbers (many of which, however, contained several species), it contains some interesting novelties, notably a species of Holomitrium quite distinct from any of the African species, a fine new Bryum of the Rosulata group, and an interesting new Braunia. The types of these and of the other novelties are in the U. S. National Museum; duplicate types are in my own herbarium. An unusual feature of this collection is the number of species generally rupestral, which were here epiphytic. This is notably the case with Grimmia ovata Web. & Mohr, Amphidium cyathicarpum (Mont.), Anomobryum robustum (the species of this genus are normally rupestral or terrestrial), Bryum alpinum Huds., Hedwigia albicans (Web.), and Ectropothecium lateriticolum Broth. The suggestion may be hazarded that these mosses formed the ancient flora of the crater, at the time when it was mostly unclothed with vegetation, and that as the phanerogamic vegetation increased and covered the rock surface the mosses were driven to the only sub- stratum left for them, viz, the stems of the tree heaths, and other wood, living or dead.

A fine species, differing in the coarsely toothed, broadly pointed, squarrose leaves from all the African species except H. acutum Wright, to which it is allied; that species, however, has’ the leaves more narrowly pointed, less sharply serrate, and with the base less widely vaginant, and the perichaetia are much shorter. The peri- stome teeth here are more or less equidistant, but very variable, some- times showing a tendency to approximation in pairs ; they are very ir- regular, but the capsules are overripe and it is difficult to know how much of the irregularity is due to wear. Each tooth is made up of two, three, or more vertical, filiform, red laminae, more or less coherent, without transverse bars below, and without striolations ; above they are pale, and closely articulate with shortly protuberant internal nodules.

The only two species of the genus hitherto found in Africa are the widely distributed D. cirrata and D. crispula. The latter differs in the plane margins of the leaves. The present species is very near D. cirrata, but appears to be distinct in the denser tufts, smaller size of all its parts, shorter capsule, and distinctly weaker nerve. CAMPYLOPUS ACROCAULON (C. M.)

I determine this with some hesitation from Negri’s description of the sterile plant from Ruwenzori. It appears to agree with that in every respect but one: the leaves are given as 7.2 mm. in length, while here they are only 4 to 5mm. long. The crowded, rigid, almost entire leaves, only the comal (fructiferous) ones finely setaceous, ate rather character- istic; the nerve is smooth at back. Capsules aggregate; calyptra smooth at base. 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOLE 72 POTTIACEAE ? TRICHOSTOMUM sp. No. 3444c.

After careful comparison of M. hyalinum Broth. with M. abys- sinicum I feel very doubtful whether the two can be kept separate. Brotherus rests his species on the smaller size and the very acute leaves, often with hyaline tip. Comparison of Holst’s Usambara plant, however, with W/. abyssinicum (No. 431, Schimp. Iter Abyssin., in Schimper’s herbarium) shows no difference, or at any rate no constant difference, in leaf. The Central African plant appears as a rule to run rather smaller than the Abyssinian specimens, but this is by no means constantly the case and Dummer’s No. 3413 is as robust as any of these. No. 3766 is smaller and agrees in dimensions with Holst’s plant, and I have retained it provisionally under M. hyalinum. No. 3756b is a very peculiar plant. The stems are elongate, robust, distantly and fairly regularly pinnate, apparently pendulous, with none of the habit of a Macromitrium, but closely resembling some forms of Papillaria. The leaves are very acutely long-acuminate, often with the apex half-twisted, and when dry somewhat recurved. I do not think, however, that the leaf form must be considered as of any importance in comparing it with M/. abyssinicum (type), as the leaves with which one is familiar there are the branch leaves, while owing to the peculiar growth of this plant the bulk of the leaves probably, and of course those of the primary stem, are of the nature of stem leaves. A seta and capsule in my specimen are identical with those of M. abyssinicum, while the specimen of No, 3413 in the Wash- 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.572 ington set indicates a distinct transition between this form and ordinary MW. abyssinicum. It is, therefore, probably only a remarkable form of that. FUNARIACEAE FUNARIA VOLKENSII Broth. Moorland, 13,500-14,000 ft.; Nos. 2391b, 3414b, both c. fr. BRYACEAE BRACHYMENIUM FLEXIFOLIUM B. & S.

No. 29 has the outer teeth more strongly bordered, the endo- stomial membrane paler and more pellucid, and the leaves with rather smaller cells, and wider border. No. 452, however, agrees quite well with Dummer’s plant in the peristome and cells, though the border is somewhat wider, showing that these characters are variable and not correlated, while here and there a leaf on Dtimmer’s No. 3423 has the border exactly asin the Abyssinian plant. - More- over, another specimen of Schimper’s (No. 552) has the leaves exactly as here. The outer teeth are densely barred, trabeculate within; the inner membrane is rather low, the processes linear, distant. BRACHYMENIUM STENOTHECUM Dixon, sp. nov. (Pl. I, fig. 3.) § OrtTHocARPUS.

These plants afford rather more interest than it usually falls to the lot of this ubiquitous species to present. They show in the same gathering a form with the leaves widely rounded at summit and obtuse, without any trace of apiculus or hair-point, and others with long hyaline hair-points, practically identi- cal with var. lanatum B. & S.; and all transitions between these extreme forms occur, even (with the exception of the form with the longest hair-points) within the limits of a single tuft. It was gathered at an elevation of 12,000 ft., on the roofs of the mud huts of the Ratmen. The Ratmen or Molemen—as their name “Mese” signifies—are a small tribe of very primitive savages inhabiting the extinct crater of this mountain. BRYUM ALPINUM Huds.

They differ somewhat from our northern B. alpinum in being robust, with the nerve very stout, excurrent in a short, acute or obtuse point, the leaves usually acute, subdenticulate at apex; these characters however are not constant and are not correlated, while some of the tufts are quite ordinary B. alpinum. The fruit also agrees exactly. I have no hesitation, therefore, in placing them under B. alpinum, which occurs also in South Africa, where, as in the Northern Hemisphere, it shows considerable variation.

INOS. 3407, 34070; 2417 b-(p: pr) jest: The vegetative characters, perichaetial leaves, and seta are so exactly similar to B. diaphana, that I thought at first, in view of the paucity of the capsules on my specimens, that it was possibly a case of malformation of fruit. However, further material from the U. S. National Museum and from Kew entirely confirmed the nor- mality of the structure, and Mr. Sim writes to me that the capsules on his three specimens—eight in all—are identical in the subglobose form, scarcely tapering at neck, all except one being more or less striate when old. In B. diaphana the capsule is narrowly elliptic, or fusiform, being narrowed to the mouth, and with a well-defined very gradually tapering neck (cf. pl. I, fig. 5b). Though often somewhat wrinkled when old, moreover, it has no sign of regular striae. Mitten, in describing the mosses collected in Central Africa by Bishop Hannington, refers a Kilimanjaro plant “ perfectly fruited ” to Hedwigia (§Braunia) secunda Hook., and raises the question, “ Are the B. sciuroides of Europe, the B. indica so luxuriant in the Nilgiri Mts., and the Abyssinian B. Schimperi, really different, or are they not most probably slight variations of one wide-spread *Journ., Linn. Soc. Bot. 22: 310. 1886. NO. 3 BRITISH EAST AFRICAN MOSSES—DIXON LEAL species?” So far as my observation goes, B. sciuroides and B. Schimperi stand on a somewhat different footing from the others; but the Indian plant is most certainly identical with that which occurs in several parts of Africa, and which has generally been known as B. diaphana. It is éspecially frequent in South Africa, where it fruits commonly. The fruit is described by Thériot ;* and Brotherus ’ says of it, “ Kapsel unbekannt.” I have several fruiting specimens from South Africa, however, and the fruit occurs on several speci- mens in the British Museum and Kew collections. Both vegetatively and in the fruit the Indian plant is exactly identical with the African, and as Mitten finds the Kilimanjaro plant identical with the Mexican there can be no doubt that they must all fall under the name B. ‘secunda, As regards the Indian and African plants at least, I do not find even the “ slight variations ’”’ which Mitten allows them. The leaves vary in the degree of plication. They may be quite without a hyaline point, or they may have a short hyaline tip, even occasion- ally a quite long, flexuose hair-point, and the perichaetial leaves vary much in length; but none of these characters shows any constancy, nor are they correlated in any way with geographical distribution. In the course of studying the Indian plant, however, I stumbled upon a very unexpected thing: In the British Museum collection. in Herb. Wilson, there are two specimens of an undetermined moss, labelled “Indies, Winterbotham,” which are identical with my B. brachytheca. I find no reference to it in any bryological works, and it appears to have remained, otherwise than in Wilson’s herbarium, quite undetected. It can scarcely be supposed that two independent species, B. secunda and B. brachytheca, would exist side by side both in Africa and in India, especially with the very restricted range that appears to appertain to B. brachytheca; and I have therefore thought it best to consider the latter as a subspecies of B. secunda.’ *Bull.

In fact the whole group of African species, NV. Hoehneliana, N. Valentiniana, and the above mentioned plants, are in my opinion quite inseparable from one another by vegetative characters alone.

The only point of doubt would be in the habitat, since the specific name of Brotherus implies a station on stonework or brickwork; but this is not of great importance, and it becomes still less so in view of the prevailing tendency towards an arboreal habitat shown by the mosses of this locality.

It is rather difficult to diagnose the somewhat numerous species of this section; but if habit, length of seta, form of capsule, and leaf outline are taken into account, it will be found that there are no African species very near this plant. FR. brachytheciiforme (C. M.) is more robust, with a foliation strikingly like that of Brachythecium albicans, and a different coloring. RR. rivuletorum is smaller, of different habit, greener, with less crowded leaves, and horizontal or subpendulous capsule. BRACHYTHECIACEAE PLEUROPUS SERICEUS (Hornsch.) Broth.

I have compared this with Mitten’s plant, and there is no doubt of its identity. It is a very striking species, but it is certainly autoicous. Mitten describes his plant as dioicous, and I have found fruiting stems on which I have been unable to detect male flowers, but there is no question that it is normally autoicous. I suspect B. gloriosum (C. M.) Par., of which the sterile plant only was described, to be the same thing. BRACHYTHECIUM UGANDAE Dixon, sp. nov. Subgen. SALEBROSIUM.

Also No. 3773 in the Kew set. This plant is exactly our European and Northern African form, golden green. The epiphytic habit is unusual, but is not unknown with us (the var. scabrellum, indeed, is usually so). FR. Holstit Broth., from Usambara, ete., is a green plant NO. 3 BRITISH EAST AFRICAN MOSSES—DIXON 17 . of a slightly different habit ; but I can find no structural differences, and I am strongly disposed to consider it only a slight form of the same thing. II. A SMALL COLLECTION OF MOSSES FROM THE ABERDARE MOUNTAINS The mosses in the following list were collected near Mount Kenia by Mr. A. Y. Allan in 1910, and were sent me for determination by Rev. D. Lillie. Although the collection is small it is of unusual interest, containing as it does the type of a new genus. CAMPYLOPODIUM EUPHOROCLADUM (C. M.) Besch. Nos. 395b, 398. This species has not previously been found in Africa. It is known otherwise from Java, Tahiti, New Caledonia, New Zealand. The second specimen above cited has very young fruit and old setae. [Campylopodium khasianum (Mitt.), a very closely allied species, indeed doubtfully distinct, differs in its fruit only, so far as I have been able to observe ; the vegetative characters described by Mitten do not appear to hold good. There is the possibility, therefore, that the African plant may belong there; but C. euphorocladum being a plant of much wider distribution (and not improbably including C. khasia- num) I have thought it best to refer this plant to the former. | DICRANUM JOHNSTONI Mitt. Dicranum Stuhlmannii Broth. Bot. Jahrb. Engler 20: 177. 18094. No. 400, c. fr. I have compared this with the original of D. Johnstoni (Kilimanjaro, H. H. Johnston 52), and it agrees perfectly. It is also identical with D. Stuhlmannii (Stuhlmann 3290b, and Volkens 1166, det. Brotherus). Mitten’s description of the leaves of his species as “ linearia, sensim loriformi-angustata,” and “ unlike any form of D. scopariwm from the narrower lower portions of the leaf,’ is very misleading, and is no doubt the cause of Brotherus having redescribed the plant. As a matter of fact, in Johnston’s specimen the leaves, though occasionally (abnormally) narrow at the base, are usually dilated there quite as in D. Stuhlmannii and other species. The fruit has not hitherto been described. Perichaetium about 6 mm. long, tubular, the bracts convolute with spreading points; seta about 2 cm. long; capsule erect, symmetrical, cylindric, with very 18 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 gradually tapering neck and no struma, dark chestnut-brown, lightly plicate when dry and old; lid finely subulate, erect or suberect; deoperculate capsule about 4 mm. long.

A remarkable little plant, the position of which is somewhat doubtful. In areolation and denticulation the leaves are very similar NO.. 3 BRITISH EAST AFRICAN MOSSES—-DIXON 19 to those of some species of Rhabdoweisia, and on this account it, might be placed in the Dicranaceae. On the whole, however, it seems to be best placed in the Pottiaceae, near Astomum and the subgenus Kleiowetsia of Hymenostomum. The plant is paroicous; but I suspect it may be heteroicous, as [| have seen what seems to be a male flower below the fertile flower. The capsule is, accurately speaking, neither cleistocarpous nor stegocarpous. The lid is perfectly differentiated, and there is a distinct row of subannular cells at the orifice; these may be in more than one series. On the other hand, the lid is probably not normally functional ; the capsule wall is of extremely delicate texture and under pressure breaks up without the lid being detached, and this appears to be the case also under normal conditions. It is unfortunate that the altitude is not recorded. The association of the plant with Campylopodium would seem to indicate a compara- tively low level. TORTULA ERUBESCENS (C. M.) Broth. No. 399; st.

MAXON (With Srx PLates) Within the past twenty years a considerable number of species have been proposed in the group of Selaginella rupestris, nearly all of which, judged by a critical comparison of their essential though minute characters, are undoubtedly well founded. In all, about twenty-five species have been described from the United States. These are so various in gross form and habit, and under a dissecting microscope or even by use of a good hand lens show such remark- ably diverse and constant leaf and sporophyll characters, that it is hard to conceive of their ever having been regarded as, for the most part, “ forms” of a single species. Extensive collecting, especially in the Rocky Mountain region, is still necessary in order to clear up the relationship of a few doubtful forms, and it is likely that explora- tion in the Southwest will yield additional new species, since the plants as a group are decidedly xerophilous or, at least, are able to withstand long periods of drought, and so may be sought in those arid out-of-the-way places that appeal chiefly to the natural history collector. Specimens from any part of the southern and western United States will, indeed, be gratefully received by the writer. Of the six species here described the first is one of the interesting assemblage of species growing together, often intimately associated, in the Organ Mountains of New Mexico; the second is a plant of the desert region of southern California, confused by Underwood with a similar species from Zacatecas, Mexico; the third, long known to the writer as distinct, is a related plant from Arizona; the fourth and fifth are species of southern California, brought to light by the _ energetic field work of a small group of enthusiastic botanists ; and the sixth is a strongly marked plant, not uncommon in the Glacier National Park, recently discovered during the course of intensive botanical collecting in that region. In the lack of a monograph or a synoptical account of the group as represented in the United States, it has seemed especially desirable to accompany the descriptions by illustrations. These, besides assisting in identification, will serve to SMITHSONIAN MISGELLANEOUS COLLECTIONS, VOL. 72, No. 5 Z SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 show very well some of the more diverse forms assumed by members of this group. All the illustrations are at natural size and represent the type specimens in each instance, excepting only that of S. arizonica which is of Thornber 315. SELAGINELLA NEOMEXICANA Maxon, sp. nov. (Pl. 1) Plants strongly assurgent, 10 to 20 cm. long, the main stem rooting sparingly at the extreme base, freely ramose, all the branches erect or ascending, several times pinnate, subequal; stems (leaves ex- cluded) mostly 0.2 to 0.5 mm. in diameter, the older ones readily defoliate. Leaves uniform, rigidly ascending on all sides, subdistant in attachment, imbricate but not wholly concealing the axis, 2 to 2.75 mm. long (seta included), the blades subulate-attenuate, 1.7 to 2.5 mm. long, 0.37 to 0.5 mm. broad at the base, setigerous (the seta 0.3 to 0.47 mm. long, whitish-hyaline from a greenish-lutescent base, straight, sparingly serrulate), thin-herbaceous, spongiose at the base, subglaucous, flat above, dorsally convex toward the narrowly obtuse apex, sparingly pilose at the base of the deep narrow median groove, ciliate, the cilia 12 to 20 on each side, slender, rigid, nearly straight, mostly 0.06 to 0.125 mm. long, spreading or slightly ascending, the apical ones reduced and more oblique. Spikes numerous, terminating the main branches, 1 to 2 cm. long, about 1.5 mm. thick, recurved, sharply quadrangular; sporophylls glaucous, yellowish brown with age, readily detached, 2.4 to 2.7 mm. long (seta included), the blade 2.2 to 2.4 mm. long, 0.9 to 1.2 mm. broad, ovate, evenly long- acuminate, setigerous (the seta 0.2 to 0.47 mm. long, greenish- lutescent with a white tip, slightly scabrous), strongly concave, with a deep dorsal groove throughout, freely short-ciliate, the cilia 25 to 32 on each side, close, stout, rigidly ascending, mostly 0.045 to 0.075 mm. long, the upper ones reduced. Megasporangia abortive or wanting. Microsporangia very numerous; microspores yellow, about 0.022 mm. in diameter. Type in the U. S. National Herbarium, No. 591262, collected in the Organ Mountains, Dona Ana County, New Mexico, at an altitude of about 1,800 meters, January 9, 1909, by E. O. Wooton. There are at hand three additional sheets of specimens collected in the same range of mountains by Mr. Wooton on September 28, 1902, Septem- ber 11, 1904, and March 3, 1907, the last mentioned associated with S. rupincola Underw. The present species has hitherto been referred doubtfully to S. bigelovu Underw., of southern California, and this is clearly its NO. 5 NEW SELAGINELLAS—MAXON 3 relationship. Selaginella bigelovii differs, however, in its more com- pact habit and rigid, funiform branches, and more particularly in details of leaf structure, the cilia being strongly oblique, very rigid, short (mostly 0.03 to 0.04 mm. long), and pointed, often incurved ; also, the setae are strongly scabrous throughout. Similar differences are found in the sporophylls, those of S. bigelovu being coriaceous, distinctly carinate, and tipped with a strongly scabrous seta. SELAGINELLA EREMOPHILA Maxon, sp. nov. (Pl. 2) Plants wholly prostrate, the main stems up to Io or 12 cm. long, coarsely radicose at intervals throughout, freely branched, forming a close mat, the principal basal divisions subequal, divaricate, 2 or 3 times pinnate, the ultimate sterile branches very short, mostly 2 to 4 mm. long, about 2 mm. broad, involute upon drying; stems, branches, and minor divisions all densely leafy, of pronounced dorso- ventral aspect. Leaves crowded, in six ranks, those of the under side the largest, about 2 mm. long, 0.5 mm. broad, exactly lanceolate, acutish, not setigerous, ciliate (the cilia about 25 on each side, white, spreading, mostly 0.075 to 0.125 mm. long), yellowish brown, im- bricate, oblique-spreading, strongly secund upon drying ; leaves of the upper side close-set, subimbricate, nearly vertical, straight or slightly curved, deltoid-subulate, acutish, not setigerous, I to I.4 mm. long, 0.4 to 0.47 mm. broad at the base, at first bright green and sub- glaucous, soon turning yellowish brown, flat above, broadly convex beneath and sulcate in a median line nearly or quite to the tip, ciliate, the cilia 6 to 12 on each side, weak, mostly spreading, about 0.1 mm. long, similar minute hairs tufted at the base of the midrib and extend- ing sparingly along the dorsal groove.

Megasporangia few, inferior, mostly basal; megaspores light yellow, 0.36 to 0.4 mm. in greatest diameter, the commissural faces finely and deeply reticulate, the outer face coarsely but sharply and deeply reticulate, the ridges about 0.016 mm. broad ; commissural costae prominent, long. Micro- sporangia numerous; microspores dull yellow, about 0.039 mm. in diameter, long remaining associated in tetrads. Type in the U. S. National Herbarium, No. 867484, collected in Palm Canyon, Riverside County, California, April 4, 1917, by Ivan M. Johnston (No. 1047) ; distributed as Selaginella parishii Underw. 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Mr. Johnston’s notes accompanying the specimen read, “ Very common in rock crevices and in their shade; Lower Sonoran Zone. It is very hard to find a rock which hasn’t a large colony of this at its foot. It grows with Selaginella bigelovu.” The following additional specimens of S. eremophila, all from the Colorado Desert region, are in the National Herbarium: CALIFORNIA: Mountain Spring, San Diego County, alt. goo meters, May 14, 1894, Mearns 3162. Top of Granite Mountain, seven miles east of Julian, April 17, 1918, Bethel. Base of San Jacinto Mountain, March, 1908, Saunders. Palm Canyon, eastern base of San Jacinto Mountain, March, 1919, Hall. West Canyon, Riverside County, alt. 200 meters, April 18, 1907, Parish 6111.- Tahquitz, near Palm Springs, December 25, 1903, Dudley. Selaginella eremophila is the plant of southern California (rare in herbaria) which has been called S. parishii. Underwoad in describ- ing S. parishit,, however, cited three collections, two of these from the Colorado Desert (Parish 1200; Saunders), and the third from Zacatecas, Mexico (Palmer 306). The California plant is specifically distinct from the Mexican element, which, having been designated by Underwood as the type, must bear the name S. parishti. The dissociation of Mr. Parish’s name from so characteristic a species of the Colorado Desert flora is especially regrettable. Of the species hitherto described, S. eremophila is closely related ~only to S. parishu, of Zacatecas, and S. landu Greenm. & Pfeiffer,” of Jalisco, both of which have a very similar dorso-ventral aspect. Selaginella parishii is a more lax plant, with the ultimate branches 2 to 3 mm. broad, and larger, narrower leaves, whose characters may be summarized as follows: Leaves of the under side 2.2 to 2.5 mm. long, with about 18 cilia upon each side, these oblique, 0.078 to 0.125 mm. long; leaves of the upper side 1.3 to 1.6 mm. long, 0.35 to 0.43 mm. broad, with 4 to 8 cilia on each side, these oblique, 0.06 to 0.09 mm. long. The sporophylls, moreover, are broadly cordate- deltoid, 1.5 to 1.7 mm. long, 1.3 to 1.4 mm. broad, with 25 to 30 “very oblique, close-set cilia on each side, those of the lower two-thirds 0.1 to 0.17 mm. long, forming a conspicuous fimbriate border. The megaspores are pale yellow, about 0.42 mm. in diameter, and delicately reticulate. Selaginella landui is represented in the National Herbarium by a portion of the type, Barnes & Land 2024 (San Esteban Mountains, 32 kilometers from Guadalajara, Jalisco) and by another collection * Bull.

The essential char- acters are as follows: Stems very firm, stiff, the branches rigid, not intricate; leaves of lower side closely appressed-imbricate, lance- attenuate, 2.7 to 3.2 mm. long, 0.6 to 0.7 mm. broad, with about 15 to 20 slender, mostly ascending cilia on each side in the lower half or two-thirds (these 0.06 to 0.12 mm. long), the apical third with pungent serratures ; leaves of the upper side crowded, rigidly vertical or recurved, narrowly deltoid, evenly acuminate, I to 1.2 mm. long, 0.4 to 0.5 mm. broad, with about 13 to 16 cilia on each side, these mostly oblique and incurved, 0.055 to 0.085 mm. long, the upper ones passing into broad pungent serratures; sporophylls deltoid-ovate, narrowly long-acuminate, 1.7 to 2 mm. long, 0.85 to I mm. broad, variable in ciliation, sometimes with as many as 20 stiff, rigidly ascending, mostly incurved cilia in the basal half (these 0.03 to 0.06 mm. long) and elsewhere serrate, or with short ascending teeth along the whole margin above the extreme base (here with a few cilia). Megaspores yellow, subglobose, about 0.33 mm. in diameter, rugulose-reticulate, the ridges projecting sharply, less than 0.008 mm. broad. These three species, S. eremophila, S. parishui, and S. landi, while readily distinguished specifically, are by no means typical members of the group of S. rupestris, and together with the next species (S. arizonica) forma fairly well-defined subgroup. The pronounced dorso-ventral habit and subdimorphous leaves are doubtless to be associated with their strongly xerophilous habitat. SELAGINELLA ARIZCNICA Maxon, sp. nov. (PIs) Plants wholly prostrate, the main stems up to 20 cm. long, rooting at intervals throughout, pinnately branched, the branches I to 1.5 cm. apart on each side, the lower and middle ones 2.5 to 6 cm. long, twice pinnate, the ultimate branches broadly subclavate, short, subdistant, all the parts densely leafy, dorso-ventral, involute. Leaves crowded, in six ranks, those of the under side the largest, appressed-imbricate, oblique laterally, linear-lanceolate, acuminate, not setigerous, 2.5 to 2.8 mm. long, 0.5 to 0.6 mm. broad, thin-herbaceous, yellowish brown, evenly ciliate, the cilia 18 to 22 on each side, oblique, up to 0.11 mm. long, the apical ones reduced ; leaves of the upper side subulate, 1.8 to 2.2 mm. long, 0.3 to 0.44 mm. broad, evenly attenuate to the acutish, whitish-marginate, short-setigerous apex (the seta dirty white, stout, 0.15 to 0.28 mm. long, serrate, often reflexed, present only in the 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 young leaves, caducous), ciliate (the cilia 4 to 8 on each side, ascend- ing, pungent, 0.04 to 0.09 mm. long, passing into short serratures at the apex), at first bright green, grayish with age, rigidly herbaceous from a thick spongiose base, rigidly ascending, with age nearly vertical in the older branches, flat above, slightly convex dorsally and deeply sulcate nearly to the tip. Spikes ascending, terminating the short ultimate divisions of the larger branches (or the divisions wholly fertile), sometimes numerous, 2 to 5 mm. long; sporophylls iarrowly ovate-deltoid, 1.5 to 1.95 mm. long, 0.75 to 0.85 mm. broad, evenly long-acuminate, at first barely setigerous (the seta 0.15 to 0.25 mm. long, broad, pointed, serrulate, dirty white), subcarinate, ciliate, the cilia 18 to 22 on each side, stout, rigidly ascending, mostly 0.03 to 0.06 mm. long, the upper ones greatly reduced, dentiform. Megasporangia numerous, basal, or sometimes interspersed among the microsporangia ; megaspores pale yellow, subglobose, 0.36 mm. in greatest diameter, coarsely reticulate on the outer face (the ridges sharp and narrow), finely reticulate on the commissural faces ; com- missural costae long, delicate. Microsporangia numerous; micro- spores orange, about 0.035 mm. in diameter. Type in the U. S. National Herbarium, no. 694327, collected at the foot of Soldier Trail, Santa Catalina Mountains, Arizona, altitude about 960 meters, July 28, 1914, by Forrest Shreve. Other specimens in the National Herbarium are as follows: ArIzoNA: Sabino Canyon, Santa Catalina Mountains, alt. 870 meters, June 15, 1903, Thornber 315. Ventana Canyon, near Tucson, 1913, Cook.

Selaginella arizonica is related to S. eremophila, and to S. land and S. parishii, whose characters are given in detail under the last preceding species. The disparity in size between the leaves of the under and upper sides is far less in S. arizonica than in the others, and it alone of the four species has the leaves and sporophylls at all setigerous. Jt is a much larger and coarser plant than S. eremophila and differs in nearly all technical leaf characters. SELAGINELLA ASPRELLA Maxon, sp. nov. (PI. 4) Plants forming a loose mat, the main stems 3 to 6 cm. long, creep- ing but not prostrate, rooting at intervals throughout, with a few NO. 5 NEW SELAGINELLAS—MAXON 7 laxly ascending branches, these close, usually intricate, 1 to 2.5 cm. long, twice pinnate, the ultimate divisions 3 to 7 mm. long, oblique, slender, all the parts scantily leafy ; main branches (leaves excluded) about 0.6 mm. thick, tardily defoliate. Leaves uniform, rigidly as- cending on all sides, subdistant, decurrent, subimbricate, 2.75 to 3.2 mm. long (seta included), the blades narrowly deltoid-subulate, 1.85 to 2.3 mm. long, 0.55 to 0.7 mm. broad at the base, long-setigerous (the seta 0.7 to 0.9 mm. long, white-hyaline, slender, subflexuous, serrulate-ciliate throughout, the cilia up to 0.04 mm. long), charta- ceous, inflated, concave above, broadly convex beneath, with a deep median groove, very strongly glaucous, with a more or less well- defined whitish-hyaline border (0.045 to 0.075 mm. broad at the middle of the leaf), ciliate, the cilia 16 to 23 on each side, spreading, straight or often curved, mostly 0.05 to 0.09 mm. long, the upper ones distant, shorter, oblique. Spikes numerous, loosely aggregate at the ends of the short apical branches, I to 2 cm. long, 1.5 to 2 mm. broad, arcuate, sharply quadrangular; sporophylls laxly imbricate, strongly glaucous, yellowish brown with age, 2.5 to 3 mm. long (seta included), the blade narrowly ovate-deltoid, evenly long-acuminate, 1.9 to 2.2 mm. long, 0.85 to I mm. broad at the base, long-setigerous (the seta stiff, straight, 0.6 to 0.8 mm. long, whitish, strongly scabrous), carinate, with a deep dorsal groove, strongly whitish- marginate, ciliate, the cilia 25 to 35 on each side, slightly oblique, mostly 0.03 to 0.06 mm. long, the apical ones few and reduced. Megasporangia few, mostly basal; megaspores pale to bright yellow, subglobose, about 0.375 mm. in diameter, lightly reticulate on all faces, the meshes broad, with low ridges; commissural costae prominent. Microsporangia very numerous; microspores bright ’ orange, about 0.033 mm. in diameter. Type in the U. S. National Herbarium, No. 867507, collected at the west end of Ontario Peak, San Antonio Mountains, southern California, altitude about 1,800 meters, in rocky ground, March 25, 1918, by Ivan T. Johnston (No. 1815). Other material, all from the same range of mountains, has been examined, as follows: San Antonio Canyon, in shelter of rock on the dry, open canyon floor, alt. 1,725 meters, July 28, 1917, Johnston 1595; Ontario Peak, in crevices of a sunny, exposed granite cliff, alt. 2,475 meters, December 22, 1917, Johnston 1807. The last-mentioned specimen is dwarfed, and the leaf parts scarcely attain the size given in the description. Selaginella asprella is a strongly marked species, without any very close relatives. Of western United States species it is related only to S. bigelovii Underw., S. rupincola Underw., and S. neo- 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 mexicana Maxon, all of which are much larger plants of essentially erect growth and differ, besides, in numerous technical characters. The very slender, rigid branches and spaced, half-appressed, strongly setigerous leaves give the plant a scant, harsh aspect, which has sug- gested the specific name. SELAGINELLA LEUCOBRYOIDES Maxon, sp. nov. (Pl. 5) Plants very closely prostrate, the stems short-creeping, 1 to 2 cm. long or less, closely aggregate, simply pinnate, the divisions thick, strongly cespitose, erect, only 2 to 7 mm. long, or the terminal ones bearing erect elongate spikes, all the parts densely leafy. Leaves crowded, closely appressed-imbricate, mostly incurved, glaucous, linear-subulate, uniform as to shape, variable in size, the basal ones 2.8 to 3.25 mm. long (seta included), 0.44 to 0.53 mm. broad, the upper ones mostly 2 to 2.8 mm. long (seta included), 0.42 to 0.5 mm. broad, all short-setigerous at the acutish whitish thickened apex (the seta stout, white, not translucent, subflexuous, 0.125 to 0.28 mm. long, strongly scabrous, often reflexed), ciliate (the cilia 8 to 16 on each side, those of the basal half spreading, 0.6 to 0.13 mm. long, the upper ones shorter, distant, ascending), thick, rigidly herbaceous, flat or broadly concave above, convex beneath (strongly so toward the apex), the median groove deep, broad, nearly percurrent. Spikes relatively numerous, aggregate, 5 to 10 mm. long, about I.5 mm. thick, erect, nearly straight ; sporophylls rigidly appressed-imbricate, deeply concave, narrowly to broadly deltoid-ovate, evenly long- acuminate, about 2 mm. long, 0.8 to I mm. broad, short-setigerous (the seta white, rigid, pointed, subentire, about 0.15 mm. long or less), ciliate-serrulate ; cilia or teeth 20 to 25 on each side, the basal cilia not more than 0.046 mm. long, pungent, oblique, passing grad- ually into oblique hyaline teeth toward the apex. Megasporangia few, basal; megaspores subglobose, bright yellow, about 0.47 mm. in diameter, the outer face obscurely reticulate, the commissural faces manifestly so; commissural costae short, elevated. Microsporangia numerous ; microspores orange, about 0.039 mm. in diameter. Type in the U. S. National Herbarium, No. 982453, collected at Bonanza Mine, Providence Mountains, southeastern California, alt. 840 meters, in crevices, rocky mountain side, March 30, 1920, by P. A. Munz and R. D. Harwood (No. 3789). The following addi- tional material is at hand: NO. 5 NEW SELAGINELLAS—MAXON 9 ® CALIFORNIA: Surprise Canyon, Panamint Mountains, Inyo County, alt. 1,400 meters, April 14, 1891, Coville & Funston 628. Vicinity of Bonanza King Mine, east slope of Providence Mountains, Mojave Desert, alt. g60 meters, May 11-24, 1920, Munz, Johnston & Harwood 42206. The relationship of Selaginella leucobryoides is difficult to deter- mine, since the plant differs not only in megaspores but in most foliage characters from all other species of the Pacific Coast region. The most striking characteristics are the extremely short, pure white but opaque seta of the leaves and the condensed, rosette-like arrange- ment of the very short branches. In habit and color there is a strong suggestion of the tufted growth of some of the smaller species of Leucobryum. The Panamint Mountains plant collected by Coville and Funston (No. 628) was mentioned as a critical form by Underwood in his initial work upon the United States species allied to S. rupestris It is clearly a reduced state of the present species, differing from the type only in its lesser size. The leaves are only 1.65 to 2 mm. long and 0.35 to 0.44 mm. broad; the seta and cilia characters are identical. The plant collected by Munz, Johnston, and Harwood (No. 4226) also comes from a higher elevation than the type collection and is somewhat smaller. SELAGINELLA STANDLEYI Maxon, sp. nov. (Pl. 6) Plants closely prostrate, the main stems up to 6 cm. long, finely radicose, pinnately branched, the larger basal branches up to 2.5 cm. long and with a few short alternate divisions, the upper branches -simple or once dichotomous, all the divisions cespitose, rigidly arcuate-ascending. Leaves crowded, imbricate, rigidly appressed, those of the older stems of a characteristic bronze color, relatively large, the blades broadly acicular, acutish, up to 2.5 mm. long and 0.6 mm. broad, with a short lutescent seta; leaves of the branches mostly dull green, oblong-linear, 2.1 to 2.5 mm. long (seta included), 0.35 to 0.45 mm. broad, setigerous at the narrowly obtuse apex (the seta 0.6 to 0.78 mm. long, lutescent throughout, coarsely serrulate- scabrous), ciliate (the cilia I0 to 14 on each side, hyaline, stiff, oblique, mostly 0.05 to 0.06 mm. long, passing into pungent serratures toward the apex), rigidly herbaceous, flat above, convex beneath and reddish along the deep median groove, especially toward the cymbi- form apex.

Megasporangia few, basal; megaspores orange-yellow, 0.46 to 0.5 mm. in diameter, oblate-spheroidal, rugose in all aspects, the com- missural costae short and prominent. Microsporangia very numer- ous; microspores dull orange, about 0.032 mm. in diameter. Type in the U. S. National Herbarium, No. 1028638, collected in the vicinity of Sexton Glacier, Glacier National Park, Montana, altitude 1,950 to 2,220 meters, on a moist rocky slope, August 7, 1919, by Paul C. Standley (No. 17228). Other material studied is as follows: Montana (Glacier National Park): Gunsight Pass and vicinity, alt. 1,775 to 2,100 meters, August 25, 1919, Standley 18136; August 25, 1917, Ulke.

ALBERTA: Tunnel Mountain, alt. 1,650 meters, June I1, 1906, Brown 95. : The writer takes pleasure in dedicating this excellent species to Mr. Paul C. Standley, who, in the course of his botanical exploration of Glacier National Park, assembled an extraordinarily rich collec- tion of material in this group, the specimens comprising (besides S. standleyt) S. montanensis Hieron., S. densa Rydb., and S. wallacei Hieron., all in ample series. Superficially S. standleyi most resembles S. watsoni Underw., of the high mountains of Utah, Nevada, and California, in which also the leaves have lutescent setae. It is at once distinguished from S. watsoni, however, by the fact that the setae (which are even darker) are not only 2 to 3 times as long but are strongly serrulate- scabrous nearly throughout, those of S. watsont being smooth or nearly so. The sporophylls also have longer and scabrous setae, and the blades are much more freely ciliate, the cilia being stiff, very oblique, and subpersistent nearly to the apex, in marked contrast to S. watson.

S. National Museum, Bul- letins of the Bureau of American Ethnology, and other series of publications issued under the direction of the Institution. Not only has our knowledge of little known regions been increased through the numerous expeditions sent out by the Institution during the 75 years of its existence, but also the collections in natural his- tory and anthropology in the Museum have been greatly enriched thereby. The urgency of some of the field-work is illustrated by the Australian expedition herein briefly described. The remarkable Australian mammal life has been but meagerly represented in the National Museum and the rapid extermination of the native animals through various agencies renders increasingly difficult the securing of an adequate collection. However very satisfactory shipments are being received from the present expedition and it is hoped that a good representation will be secured for the Museum before it is too late. GEOLOGICAL EXPLORATIONS: IN THE CANADIAN ROCKIES During the field season of 1920, geological exploration was con- tinued by Secretary Charles D. Walcott in the Canadian Rocky Mountains, with two main points in view, (1) the determination of the character and extent of the great interval of non-deposition of sedimentary rock-forming material along the Front Range of the Rockies west of Calgary, Alberta; (2) the clearing up of the rela- tions of the summit and base of the great Glacier Lake section of 1919° to the geological formations above and below. The party going from Washington consisted of Dr. and Mrs. Walcott and Arthur Brown. *Smithsonian Misc. Coll., Vol. 72, No. I, 1920, p. 15. SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 72, No. 6.

The route taken was along the north shore of Lake Minnewanka (fig. 1, Frontispiece) and through the Devils Gap to Ghost River, which here runs north and south at the foot of high eastward-facing cliffs of Cambrian limestone, capped by limestones of Devonian age. Lake Minnewanka is a beautiful sheet of water (fig. 2) in the broad bottom of a pre-glacial river channel, the eastward extension of which forms the Devils Gap. The Rocky Mountain front (fig. 3) is formed of masses of evenly bedded limestone that have been pushed eastward over the softer rocks of the Cretaceous plains-forming rocks.

Photograph by C. D..Walcott, 1920. Ghost River Gap and other openings were cut through the cliffs by running water and rivers of ice. Great headlands (fig. 4) and high buttes (fig. 5) have been formed by the silent forces of water and frost, many of which stand out against the western sky as seen from the distant foothills and plains. It was among these cliffs that we found that the first great cliff (figs. 3 and 4) was of lower Middle Cambrian age, and that resting on its upper surface there were 285 feet (86 m.) of a yellowish weathering magnesian limestone, here named the Ghost River forma- tion, which represents the great lost interval between the Cambrian below and the Devonian above. Sixty miles to the west, over four miles in thickness of limestone, shales and sandstones (22,670 feet (6,890 m.) ), occur in the lost interval of the Ghost River cliffs.

In the north- ward-facing cliffs 25 miles (40 km.) east of the Glacier Lake section of 1919, and 4o miles (64 km.) north of Lake Louise, a geological section was studied that tied in the base of the Glacier Lake section of 1919 with the Middle and Lower Cambrian formations. Return- ing up the canyon valley of the Siffleur River to the wide upper valley of the Clearwater River, a most perfectly exposed series of lime- stones, shales, and sandstones of Upper Cambrian and later forma- tions was found (fig. 6) which cleared up the relations of the upper portion of the Glacier Lake section to the Ordovician formations above. The field season was marred by forest fire smoke in July and August, and almost continuously stormy weather in September. Some of the incidents of the trail are illustrated by figures 7-12. The trout of Lake Minnewanka (fig. 9) increased our food supply for days while on Ghost River, and the camp on the Clearwater was a paradise for man and beast (fig. 7). On Pipestone Pass the avalanch lily was found forcing its way up through the hard snow (fig. 10), and in a treacherous ford of the Pipestone River, Arthur’s war bag and the sugar and flour got a soaking. The party is indebted in many ways to the officials of the Rocky Mountains Park, and to the officials of the Canadian Pacific Railroad, all of whom gave assistance whenever it was possible to do so. GEOLOGICAL FIELD-WORK IN-THE UNITED STATES Dr. R. S. Bassler, Curator of Paleontology, U. S. National Museum, was engaged in field-work in Ohio and Illinois during the latter half of June and the first part of July, with the result that two large, instructive exhibits and important additions to the study series of fossil invertebrates were obtained. Proceeding first to Northside, Ohio, Dr. Bassler made arrangements for the shipment to Washing- ton of a large, well-preserved fossil elephant skull which had been purchased by the Museum through the efforts of Dr. E. O. Ulrich, Associate in Paleontology. This specimen, discovered in glacial gravels near Cincinnati some years ago, was long the prize exhibit of a local saloon; in fact, it was so highly regarded for advertising purposes that repeated offers of a considerable sum for its purchase were invariably refused. With the coming of prohibition, its former usefulness departed and the Museum was able to secure it for a NO. 6 SMITHSONIAN EXPLORATIONS, 1920 eit nominal amount. Teeth of this species (Elephas columbi Falconer) are contained in our collections, but such a complete skull is of rare occurrence, there being only one or two others in North American museums. The specimen is further valuable in giving evidence as to the proper position of the tusks in the skull, a subject of long controversy. The second important exhibit secured during the trip was a slab, measuring four by eight feet, of highly fossiliferous limestone from the Richmond formation of Early Silurian age as exposed near Fic. 13.—Beginning of excavation for exhibition slab of Richmond limestone near Oxford, Ohio. Photograph by Bassler. Oxford, Ohio. Such a specimen had long been desired for the exhibition halls to show the advancement in life from the primitive Cambrian forms, represented in the large Cambrian sea-beach sand- stone exhibit, to the higher and more complex species of succeeding geological periods, but notwithstanding the numerous occurrences of fossiliferous limestone of Ordovician and Silurian age, it was not until 1920 that a layer affording slabs of suitable size and sufficient perfection of preservation was brought to the attention of the Museum. This was discovered by Dr. W. H. Shideler, Professor I2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 of Geology at Miami University, Oxford, Ohio, who most generously assisted in quarrying out the specimen. As shown in the accompany- ing photograph (fig. 13) representing the begining of the excavation for the thin bedded, fossiliferous layer desired (marked -r), numerous large blocks of stone had to be removed before the real task of quarrying the slab was begun. The work was completed successfully and the exhibit is now being installed in the hall of invertebrate paleontology. The perfection of the fossil shell remains on this slab iS i * Fic. 14.—Surface of fossiliferous limestone slab, one twenty-fifth natural size. Photograph by Bassler. is evidenced in figure 14, which, however, shows only in a small degree the distinctness of the shells upon the rock background. Upon the completion of the quarrying operations at Oxford, Dr. Bassler proceeded to Chicago, Illinois, where he was engaged in the preparation of casts of type specimens of fossils contained in the collections of the Walker Museum, University of Chicago. The paleontological collection of the National Museum, which includes the celebrated Walcott, Ulrich, Springer, Harris, Nettelroth, and Rominger collections, is especially rich in type specimens of Early Paleozoic fossils, but nevertheless the Walker Museum possesses No. 6 SMITHSONIAN EXPLORATIONS, 1920 13 many unique types not represented at all in Washington. Permission to prepare casts of these and thus advance our study series toward the completeness which the National collections should attain, was generously granted by Dr. Stuart Weller, Director of the Walker Museum. In two weeks time Dr. Bassler was enabled to finish cast- ing all of the Ordovician and Silurian types, leaving the remaining Paleozoic species for a future trip. The work was done quickly by using the modeling compound (plastocene) to make the mold from which the cast is prepared. After dusting the fossil with talcum powder the modeling compound is carefully pressed upon it and then withdrawn, thus securing a clear-cut impression into which the plaster is poured. Bubbles can be avoided by first pouring thin plaster of Paris into the mold and distributing it uniformly with a camel’s hair brush. The thicker plaster is then introduced as usual to fill the cavity. When dry the modeling compound is torn away, thus leaving the complete cast but also, unfortunately, destroying the mold. Field-work in vertebrate paleontology was limited to a short trip made by Mr. J. W. Gidley, Assistant Curator, in the latter part of August to Williamsburg, Virginia, where scattered remains of a fossil whale had been found in the Miocene strata outcropping nearby. It was at first hoped that an entire skeleton could be secured here, but careful search proved the bones to be so scattered and fragmentary that no exhibition material was available although some interesting additions to the collection of fossil vertebrates and some excellent Miocene shells for the exhibition series were obtained. Mr. William F. Foshag, of the Division of Mineralogy, at his own expense made sundry trips into interesting mineral localities in Cali- fornia and secured a considerable quantity of desirable material for ‘ the Museum’s collections, including an excellent series of borax minerals. FIELD-WORK IN ASTROPHYSICS In astrophysical research the Institution was unusually active. Early in 1920, Dr. Abbot had a long discussion and correspondence with Professor Marvin, Chief of the United States Weather Bureau, on the applications of solar radiation measurements to meteorology now being officially practised in Argentina and Brazil on a basis of daily telegraphic reports from the Smithsonian observatory near Calama, Chile. Professor Marvin felt strongly the inadequacy of existing solar radiation observations as a basis for studies of the dependence of temperature on the solar variation. While the Chilean results might be excellent, still they were for the most part not 2 14 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 checked by independent observations. The Mount Wilson work yielded results on less than a third of the days, and might well be affected by variations of atmospheric humidity incident to the site so near the Pacific Ocean and the cities about Los Angeles. These objections could not but be admitted by Dr. Abbot, and led him to make a great effort to strengthen the observations of solar variation. Mr. John A. Roebling, of New Jersey, had indicated a strong interest in the work. In conference with Dr. Abbot in May, 1920, he generously gave the sum of eleven thousand dollars for the purposes oh ee ee Be sare ea pM oR i : he hs ay, ae : vee eet betes, te ee Piller SA PS Fic. 15.—Montezuma solar observ- Fic. 16.—Montezuma solar observ- ing station near Calama, Chile. ing station.

Wilson to the best mountain site available in the United States; third, the balance for any other objects closely associated with these investigations. Under the zealous and able management of Director A. F. Moore, a new observing station was selected and prepared at a place called Montezuma, about 8 miles south of Calama on a mountain rising about 2,000 feet above the local level, and about 9,500 feet above sea SMITHSONIAN EXPLORATIONS, 1920 15 NO. ‘asnoy SuljamMq ‘BUINZI}UOW 3 UOI}e}S BurArasqo “EUINZaJUOPY Je UOI}e}S BuUlALasqO AvJOS—oz7 “DIYy IeJOS dy} JOF eCwR[eD WoOIT sjersajeu Suljnep]—O6l1 ‘oy "poyeoo] st A1OJLAJOSGO dy} YIM uO yeod oy, “wore}s SurAtasqo 1ejOs euInza}JUOJY—'gI “OI ‘snyeiedde drajaworeyszdd pue }BJSOJIOD) “UOI}LJS SUTATISqO ARJOS VUINZaJUO[—ZT “MJ 16 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 ae ie Fic. 21.—Town of Wenden, Arizona.

Observers’ quarters, computing rooms, garage and shop are located some three hundred feet lower in a sheltered ravine. These quarters can be reached by the auto truck in 50 minutes drive from Calama. No road had to be constructed, as there are no trees in the region, and a way was found smooth enough, and of sufficiently easy grade, without working. Within about two months of receipt of the Institution’s telegram, Mr. Moore completed these arrangements, removed the VE tw jill Y nw Fig. 23.—Observatory on Mt. Harqua Hala. outfit from its former location and recommenced observing August 5, 1920, at Montezuma with the loss of but ten days for the removal. He regards the new site as excellent, and expresses doubt if a better one could be found in the whole world. In December, Mr. Moore returned to the United States, turning over the Directorship of the Chile Station to Mr. Leonard H. Abbot, formerly assistant, who is now assisted by Mr. Paul Greeley. Tele- grams giving the values of solar radiation observed are sent as heretofore to Buenos Aires and forwarded from there to Rio de 18 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Janeiro. Both the Argentine and Brazilian Weather: Bureaus employ them with approval for forecasting purposes. Dr. Abbot, with the advice and assistance of the U. S. Weather Bureau, which carried on special observations in several localities for the purpose, selected a site on Mount Harqua Hala, near Wenden, Arizona, as the best place to relocate the Mount Wilson outfit. A building, partly underground, was erected there in July and August by local contractors. Messrs. Abbot and Aldrich occupied the Mount Wilson Station as usual from July 1 to September 15, when the outfit Maes ‘ o ae its SEL ae at hall = Fic. 24.—Coelostat and pyrheliometer, Mt.

Mr. Aldrich then relieved Dr. Abbot, and it is expected will himself be succeeded about’ May 1, 1921, by Mr. A. F. Moore, formerly at Calama. Thus the Institution has now in charge two first-class solar radia- tion observatories, which are to be operated continuously hereafter until the question of the value of the solar variation as a meteoro- logical datum is definitely settled. Heretofore the measurements have NO. 6 SMITHSONIAN EXPLORATIONS, 1920 19 been secured on nearly 70 per cent of the days at Harqua Hala and on nearly 80 per cent at Montezuma. The agreement of results on days in common has hitherto been remarkably close and leads to the hope of surely detecting solar variations as small as 1 per cent. The conditions of living at Montezuma, while lonely, are not excessively so. Frequent motor trips to the city of Calama for supplies, and occasional visits to the copper mine at Chuquicamata, where great kindness is experienced, help to break the monotony. At Mount Harqua Hala, however, the isolation is excessive. There cme RAK NN EOE SIRE nse eALERTS TRE ET . * _ ee ee ee . ar oo eaenen Fic. 25—Top of Mt.

It is 11 miles from Wenden to the foot of the mountain trail, which is 5 miles more in rising about 3,000 feet. Mail 1s received only about once in two weeks, when supplies are ordered by heliograph signaling with Morse code to the merchants in Wenden, at the cost of several hours hard work with the lights. Water must be hauled from Mr. Ellison’s camp, over a mile distant and 850 feet below, except when at rare intervals rain falls. The two observers 20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 cook, wash, cut firewood from the small oak bushes and dwarf yuccas about, and repair or alter the building or the apparatus as occasion requires, besides carrying on the solar investigation. During the occupation of Mount Wilson in 1920, many pieces of research were successfully carried through by Messrs. Abbot and Aldrich besides the measurements of solar variation. One of the most interesting was the perfecting of the solar cooker begun several years ago.

A continuous circu- lation of the heated oil keeps the ovens hot enough to perform all cooking operations except frying. Excellent bread, meat dishes, vegetables, cereals, canned fruits and vegetables and preserves were cooked there by Mrs. Abbot, who had charge of this part of the experiments and who was much envied for her cool kitchen and novel appliance by the ladies of the mountain. This solar cooker was con- structed on Dr. Abbot’s plans largely at the cost of grants from the American Academy of Arts and Sciences in Boston, and the National Academy of Sciences. It has proved successful, but must be regarded No. 6 SMITHSONIAN EXPLORATIONS, I920 2. at least for the present as rather a luxury for rural and relatively cloudless regions, than as a generally useful appliance.

Shantz, Botanist, Office of Seed and Plant Introduction, Bureau of Plant Industry, United States Department of Agriculture, was also a member of the Smithsonian African Expedition, and his chief objects were to secure live plants of agricultural value for intro- duction into the United States, to study the agricultural methods of both natives and Europeans, and to collect plants for the National Herbarium of the United States National Museum. This work began at Cape Town, August 13, 1919, and terminated at Port Said, Sep- tember 2, 1920. The vegetation of the Cape region has long been known to Euro- pean botanists, and has received more attention than that of any other portion of Africa. It is difficult to imagine a region which has so many striking features. The wealth of Proteas and Ericas alone would make this region unique. Lilies of various and beautiful types, Iridaceae, Amaryllidaceae, and Orchidaceae, each represented by many genera and species, the Arum lily or calla, which occurs every- where in wet soil, and Pelargoniums, which here cover the mountain sides, make of this Cape region a natural botanical garden, so rich and varied that any botanist will here find plants of absorbing interest. At Kirstanbosch there has been established the National Botanic Gardens now under the direction of Dr. R. H. Compton. If the well- laid plans are fully carried out, it will be possible to find here all of the more interesting indigenous plants of South Africa, and to this garden will come botanists, horticulturists, and agriculturists inter- ested in South African plants. American botanists would be proud if we had anywhere in our country a garden to compare with it. East of Port Elizabeth in the Addo Bush, which is a low thorn thicket of trees and vines about 15 to 20 feet high, are food plants of especial interest. Among the succulents, none are more interesting than the speckbroom (Portulacaria affra), a source of forage for the wild elephant herd of the bush as well as for other large herbivora, ostriches, cattle, sheep, or other domesticated animals. This plant has been introduced into the United States and is doing especially well in southern California in the lower chaparral zone and should greatly improve the forage value of the natural range. Here are many interesting plants such as the picturesque Acacia horrida, with 32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 its large white spines, the Boer Bean, Schotia speciosa, the young beans of which are cooked and eaten, also many interesting Aloes, Lilies, Cotyledons, and Euphorbias. The elephants’ foot (Testu- dinaria elephantipes) and many species of asparagus also occur here. The Karroid plateau was seen only during the rest period, when its vegetation, which consists of desert grasses and shrubs, is in appear- ance identical with portions of the Great Basin in Nevada. Especially interesting features of this desert are the great number of species of i Rag? Fic. 44——On the Karroid Plateau, west of De Aaar.

Mesembryanthemum, several of which are edible, and the Karroo bush (Pentzia), a valuable forage plant, areas of which resemble in general appearance our Bud Sage areas of Nevada and Wyoming. Passing northwest to the region about Kimberley, there is a scattered growth of Acacias, over an open desert grass type similar in some ways to the vegetation of west Texas and portions of Arizona and New Mexico. The high grasslands of the Transvaal, on the other hand, with a grass vegetation dominated by Themeda forskalu, reminds one of Andropogon scoparius areas in the drier portions of No. 6 SMITHSONIAN EXPLORATIONS, 1920 33 our prairies. Here corn is the principal crop and the large ranches with houses far apart, each with a clump of trees, make the resem- blance to our prairies in the earlier days even more striking. The portion of the Transvaal north of Pretoria, known as low Veld, consists of a scattered growth of relatively small trees over a grass cover composed of rather coarse tall grasses. This is one of the most widely distributed types and an exceptionally interesting one. The grasses are burned off each year and only such trees as can resist the fires can maintain themselves under this condition. This type becomes somewhat modified at Lourengo Marques, where the vegetation, although quite luxuriant, still showed signs of a prolonged drought period. Here, as in the region north of Pretoria, the Kaffir Orange (Strychnos pungens) is abundant, and there are many species of Acacia and Combretum. The Cashew Nut (Anacardium occi- dentale) is everywhere a prominent tree and has the appearance of being indigenous, although introduced from South America. It forms a large evergreen tree and is never cut down by the natives, who prize it both for the fruit and for the nut, from which they secure both food and a strong alcoholic beverage. Another tree of unusual interest is the Morula (Sclerocarya caffra), which has a valuable oil and edible nut, with a fruit useful for making jam and an alcoholic drink. Of the more strikingly beautiful trees of this section are the red flowered and fernlike-leaved Delonix regia, the beautiful blue flowered Jacaranda, and the Mahogany Bean (Pahudia quanzensis) which produces in its large pods a large black bean with a brilliant scarlet cup-shaped aril at the base and is one of the important timber trees. The vegetation at Salisbury reminds one of the low Veld above Pretoria, a grassland with scattered trees, singly or often in clumps. At Bulowayo the grasses are less luxuriant and the trees smaller and more xerophytic. The vegetation about Victoria Falls, except for the small forest irrigated by spray from the falls, is also xerophytic in character. At Kafue the grasses seem more luxuriant but the trees are much as at Victoria Falls. Here a number of important fruits were secured, most of which are still undetermined. A nut tree of unusual interest, because of its value for food and oil and the remarkably light weight of the wood, was secured here. It has been known as the Manketti Nut (Ricinodendron rautanenu). Here also occurs the Beobab (Adansonia digitata), the largest tree in Africa, useful to natives as a source of Bast fiber and as food. The acid white pulp which fills the fruit and surrounds the seed is eaten or dissolved in water to produce a refreshing drink. 34 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 The dry, open forest around Elizabethville gives way, before Bukana is reached, to the tall grass and scattered trees which form the great Savanna, which surrounds the tropical forest of the Congo.

The oil palm, which belongs to the native who planted it, is probably the most useful native plant in all Central Africa, and its oil is used by the natives as food and for making soap with which to wash their clothes. The dense tropical forests which cover much of the central Congo were seen at Kindu on the Congo River, where they form a dense canopy, but where the undergrowth is not entirely shut out. At Kigoma and Ujiji, on Lake Tanganyika, the grassland is dotted with NO. 6 SMITHSONIAN. EXPLORATIONS, 1920 35 large mango trees, the fruit of which is large and of excellent quality.

There are several small tropical forests in Uganda, and at Entebbe an unusually interesting botanical garden.

At Entebbe one may see Para rubber, Cera rubber, Cacao, sugar cane, yams, corn, rice, wheat, and other temperate crops har- vested at the same time. The principal results of the expedition were the collection of about 1,000 botanical specimens for the National Museum, and the introduc- tion of about 1,600 plants for growth as agricultural plants in this Fic. 49.—The Uaso Nyiro River at Archer’s Post.

The acquaintance was made of many men interested in plants and agriculture, throughout the Continent, who can be of service 1n connection with securing additional material. First-hand observations were made of the methods of agriculture pursued by African tribes as well as the Europeans, and a large number of photo- graphs were taken which illustrate the natural vegetation and agri- cultural crop methods. NO. 6 SMITHSONIAN EXPLORATIONS, 1920 39 AUSTRALIAN EXPEDITION During the past year Mr. Charles M. Hoy has continued the work of collecting material in Australia, under about the same conditions as those mentioned in the last report on explorations. In this period collections were made at the following localities : “Farina, S. A.: Work in the Farina district was done at Lindhurst, 30 miles east of the town of Farina. Nineteen days were spent there, resulting in the collection of 110 birds and 64 mammals. A few reptiles and insects were also collected.” “Kangaroo Island, S.

A few miscellaneous specimens including reptiles, crustacea, etc., were also obtained.” “Busselton, W. A. (50 miles south): Camp was pitched 50 miles south of the town of Busselton, on the edge of the Government Timber Reserve. Forty days were spent in camp (May 14-June 23). The weather was the worst that I have experienced. During the whole 40 days, there were only three days free from rain. Over 18 inches fell in that time. It was impossible to keep things dry and even the tent fly went green with mould. Despite these handicaps, however, a pretty fair collection was obtained. The collec- tion contains 94 mammals, 46 birds and a few miscellaneous alcoholic speci- mens (reptiles and land shells).” 40 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Fic. 51.—A rufous rat-kangaroo from New South Wales.

In the last letter received from Mr. Hoy, from Port Darwin, Northern Territory, dated September 25, 1920, he writes, in part, as follows : NO. 6 SMITHSONIAN EXPLORATIONS, I9Q20 43 “T have decided to work the Northern Territory and then go overland to Queensland via the old wagon road. I will travel in a buckboard and will go south from here, to the Catherine River, then east along the Roper, and then to the McArthur. On reaching the latter river I will go south along the river, then to Anthony’s Lagoon and east across the tableland to some point in Queensland—most likely Gloncurry. The trip will take about four months and will have many advantages. The road is an easy one, being an old estab- lished route with plenty of good water along the way, and the trip ought to be productive of very good results.” During the year two shipments were received from Mr. Hoy, the last one arriving here in September. A total of 440 mammals, well prepared, several of which were hitherto unrepresented in our collec- tion, together with series of skeletal and embryological material ; 570 bird skins, with 24 additional examples in alcohol, and smaller collections of reptiles, amphibians, insects, marine specimens, etc., were received. Up to the time of Mr. Hoy’s visit to Australia the Museum had received not over goo specimens of birds from that country; the majority of these were old, mounted, and without precise data, some of them dating back to the time of the Wilkes Exploring Expedition. About 350 mounted birds, displayed at the Centennial Exposition in Philadelphia in 1876, by the several Australian colonies, and pre- sented to the National Museum at the close of the exposition, formed the largest single contribution to our collection; the remainder of the material consists of many smaller lots, obtained by gift or ex- change at long intervals. About 140 species, including several of the distinct forms of Kangaroo Island, are represented in the material received from Mr. Hoy, all well prepared and with adequate data. Some of them are quite new to the Museum collection, and others, ‘such as the lyre bird, have not previously been available in our study series. BIOLOGICAL EXPLORATION IN HAITI Dr. W. L. Abbott, of Philadelphia, accompanied by Mr. E. C. Leonard, of the National Museum, as botanical collector, made a visit of exploration to southern Haiti from February to July, 1920. Dr. Abbott undertook this visit chiefly that he might study the bird life of Gonave Island, hoping to complete certain series he had col- lected on a former visit. The island is about 30 miles long and Io miles broad, and consists of a low mountain range bordered by a belt of foothills that merge gradually on the north coast to a level beach fringed by mangroves, but on the south slope descend rather abruptly into the sea. Dense thorn thickets cover the arid mountain sides and foothills, while the uplands, called La Table, open into 44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 large grassy tracts with only occasional trees or shrubs. Due to the scarcity of water and, in many places, to large outcrops of bare coral rock, the island is poorly adapted to agriculture, but the grassy up-~ lands furnish excellent grazing. The forests yield a fair amount of lignum vitae. The party spent three weeks on the north coast, work- ing around Anse Galette and Etroite, and later a week on the south coast in the vicinity of a small fishing village called Pikmi. The regions visited on the mainland were St. Marc, Etang or Manneville, Fond Parisien, La Mission, Furcy, and Pétionville, with Port au Prince as base. ian ex al “ot Se NBeae bu « Fic. 56.—Royal Palm groves of Fond Parisien. Etang is on the northwest shore of Etang Saumatre, a large lake nearly 20 miles east of Port au Prince, bordered on the west by the plains of the Cul de Sac, on the north by the mountains of Grand Bois, and on the south and east by the foothills of La Selle Moun- tains. The lake is about 50 feet below sea level and very salty. Among the interesting natural features of the region is a series of large springs, flowing into the lake through a belt of marshy meadows which are covered by a short sod composed almost entirely of several species of sedges. An excellent opportunity was offered to study both the arid cactus forests and cat-tail marshes that occur in the Cul de Sac. The large royal palm groves of Fond Parisien, situated on the southeast shore of Etang Saumatre, give it a picturesque appearance, NO. 6 SMITHSONIAN EXPLORATIONS, 1920 45 In old French times Fond Parisien was considered one of the most beautiful spots in Haiti, but a flood has covered the greater part of this once fertile district with stones and gravel, transforming it into a desert.

The natives are, however, rapidly destroying the pine trees both by burning the forests repeatedly and by girdling the pines for splinters, which are sold in the markets as kindling. Furcy and Pétionville are not far from Port au Prince. Both are easily accessible and are among the few localities which have been visited by naturalists. Nearly 10,000 specimens of plants were collected, as well as a number of land shells and insects. The birds obtained by Dr. Abbott during this expedition numbered 201 skins, with a few alcoholic specimens and skeletons. By far the most interesting ornithological observation made was the discovery in some abundance of an introduced weaver bird, Hyphantornis cucullatus (Muller), a native of West Africa. This species was found at several points in Haiti, where it occurs in colonies and affects much the same type of country as do related species in Africa. Nearly completed nests, without lining, were found about the middle of May, but no eggs had been deposited at this date. They are strongly woven of narrow strips of palm or banana leaves, and have an entrance at the side. An illustration of the manner of nest- ing is shown in figure 59. Two smaller species of west African weavers, belonging to other genera, are known to occur in Porto Rico, where they have existed for many years, but the date and circum- stances of their introduction, as well as those of the species dis- covered in Haiti, are at present unknown. MALACOLOGICAL FIELD-WORK IN CALIFORNIA AND THE HAWAIIAN ISLANDS On the way to the First Pan-Pacific Scientific Congress held in Honolulu, August 2-20, 1920, Dr. Paul Bartsch, curator of mollusks, U. S. National Museum, stopped for three days in Glacier National Park, where some collections were made. He also spent a day on shipworm investigation about Mare Island, where he had placed at his disposal, by the commandant of the station, a tug and pile extractor, and the necessary officers and men to make every minute of his stay count, the result being a careful examina- tion of pilings throughout the stretch of San Pablo Bay and the adjacent shores of San Francisco Bay. This investigation resulted in establishing the fact that the mollusk which has been doing the damage estimated at some $25,000,000 last year is a new species of Teredo, which Dr. Bartsch has named Teredo beachi in honor of the commandant of Mare Island. 48 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOLE 72 Dr. Bartsch, in preparing a monograph on the land shells of the Epiphragmophora californiensis group, was very much puzzled how to account for the presence of two very closely related subspecies at Pt. Pinos, California. He took this occasion to visit Pt. Pinos, and there found that the two subspecies do not occupy the same habitat. The smaller of the two was found in great abundance under plants on two of the rocks lying off the Point, separated from the mainland by a gap across which one could easily leap, while the larger sub- species, which was rather rare, was found on the ground, buried beneath needles and vegetable detritus. Two subspecies of the Fic. 60—The home of Epiphragmophora californiensis Lea, a species of land shells, off Pt. Pinos, California. Epiphragmophora tudiculata group were found to occupy a similar range. Mr. Henderson and Dr. Bartsch arrived in Honolulu a few days prior to the meeting, and this time was used for collecting land, fresh-water, and marine shells on the island of Oahu. They also collected mullusks during their sojourn about the wonderful crater of Kilauea, on the occasion of the visit by the congress to the island of Hawaii. Several stations were likewise made between Kilauea and the Kohala coast. A large number of marine shells were secured from the rocky shores of Honaunau Bay. Since the first accommodations to be secured for the return were dated September 8, the intervening time between the close of the NO. 6 SMITHSONIAN EXPLORATIONS, 1920 AQ congress and this date was spent in collecting specimens. Dredgings were made in Pearl Harbor, where the commandant placed one of the dredges at their command. They were also rendered the neces- sary assistance in making a search for shipworms, with the result that a new species of Teredo was discovered, which has been named Teredo parksi, in honor of Admiral Parks, in charge of Yards and Docks, U. S. N. They also dredged in Maunalua Bay, on the south side of Oahu and in Kaneohe Bay, on the east side of the same island. Specimens were also collected on various occasions at Haleiwa Beach, on the north end of Oahu, and the beach and shallow water adjacent to their cottage at Waikiki were thoroughly scratched over. Trips were also made into various parts of the mountains, where land shells of many kinds were secured. Another excursion carried them to the island of Maui, where marine shells were collected wherever possible along the shore, and land shells were secured on their ascent of the magnificent extinct voleano of Haleakala. One of the very interesting observations made on this trip to the Hawaiian Islands was the finding of an existing marine flora and fauna at a considerable elevation above the level of the sea on the gently sloping bench at the southeast point of Hanouma Bay. This flora and fauna consist of algae, quite a number of species of mollusks, crustaceans, echinoderms and other marine organisms, which occupy pools and puddles kept ever moist and supplied with fresh water by the spray from the breaking surf, which incessantly pounds that shore. Dr. Bartsch considers this an important observation, since the occurrence of fossiliferous laminae bearing marine organisms be- tween sheets of lava has been held to indicate that they were deposited ‘at or below sea level and their occurrence above this has been held as evidence of elevation. We have here an instance which indicates that this is not necessarily the case, for such a lamina would be pro- duced if a new outpouring of lava were to cover up the place mentioned. BOTANICAL EXPLORATION IN JAMAICA In February, 1920, Mr. William R. Maxon, Associate Curator in the Division of Plants, United States National Museum, and Mr. Ellsworth P. Killip, aid, were detailed to make botanical col- lections in Jamaica.

Through the kindness of Mr. J. G. Kieffer, general manager of the United Fruit Company in Jamaica, a house on the company’s plantation at Windsor, in the rich banana region south of Port Antonio, was placed at the disposal of the party. About 10 days was spent here, trips being made to Mooretown, Mill Bank, Cuna Cuna Pass, and the northern foothills of the John Crow range. > Se ae Fic. 66.—A characteristic fern (Dicranopteris bifida), growing in vinelike masses near Morce’s Gap. The most productive period was one of three weeks in March, spent in the Blue Mountain region, with headquarters at the botanical station at Cinchona, the lease of which had been renewed by the Smithsonian Institution in January, 1920. Located on a projecting southern spur at an altitude of 1,500 meters, equipped with a service- able laboratory and most comfortable living quarters, Cinchona served as an excellent base for botanical exploration in the Blue Mountain region, most of the peaks lying within fairly easy reach. Extensive collections were made on John Crow Peak, at New Haven Gap and Morces Gap, and in the vicinity of Cinchona, as well as on trips to Thompson’s Gap, Hardward Gap, and the summit of Blue Mountain 54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Peak. Over 800 numbers were collected in this region. In prepara- tion for a projected work by Mr. Maxon on the ferns of Jamaica, particular attention was paid to this group, nearly 200 species being here collected. Other regions visited include Hollymount, on the upper slopes of Mount Diabolo, in the central part of the island, the coastal territory of Montego Bay, and the southern border of the “ Cockpit Country,” the last a wild, little inhabited, wooded area of innumerable limestone sinks lying southeast of Montego Bay. Collections at Cook’s Bottom, Mulgrove, Mocho, and Ipswich yielded a number of new or otherwise very interesting species. Just before leaving Jamaica Mr. Maxon made a brief visit to Pigeon and Great Goat islands, lying off Old Harbour. Much of the success of the trip is due to assistance extended freely by officials of the United Fruit Company, acknowledgment of which is gratefully rendered. BOTANICAL EXPLORATION IN BRITISH GUIANA Mr. A. S. Hitchcock, Custodian of Grasses, visited British Guiana, making the trip through the co-operation of the United States De- partment of Agriculture, the New York Botanical Garden, and the Gray Herbarium. He left New York, October 4, 1919, and arrived at Georgetown, October 22, stopping on the way at St. Thomas, St. Croix, St. Kitts, Antigua, Guadeloupe, Dominica, Martinique, St. Lucia, and Barbados. He left Georgetown, February 2, 1920, and arrived in New York, February 16, stopping four days in Trini- dad and one day at Grenada. Six weeks were spent at Georgetown, and other points along the coast; three weeks at the Penal Settlement on the Mazaruni River, from which were visited Bartica, Kalacoon, and Kartabo; two weeks on a trip up the Demerara, Essequibo, and Potaro rivers to Wismar, Rockstone, and Tumatumari; and ten days on a visit to the North- western Distict, including Morawhanna on the Barima River, Isso- rora, the Rubber Station on the Aruka River, and the Yarikita Police Station on the Venezuelan border. Four sets of plants were collected including 1,134 numbers, with extra sets of the grasses. On account of the extremely damp climate it was necessary to use artificial heat in drying the specimens. Two oil stoves were kept burning night and day, the specimens being between corrugated paper. After drying, the plants were sprinkled with naphthalene powder to prevent subsequent molding. NO. 6 SMITHSONIAN EXPLORATIONS, 1920 55 British Guiana has an area of about 90,000 square miles, is about 400 miles deep, and extends about 250 miles along the coast (Lat. 1°-8° N., Long. 57°-61° W.). There are three counties: Demerara, including the drainage system of the Demerara River and to the Abary River on the east; Essequibo, including the drainage system of the Essequibo River and all to the west; and Berbice, including Fic. 67.—St. Thomas.

The only other city is New Amsterdam, at the mouth of the Berbice River, with a population of about 9,000. The entire population of the colony is about 300,000, about 4,000 of whom are whites. The bulk of the population consists of East 50 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Indians (42.7 per cent) and negroes (39 per cent). The chief product of the colony is sugar, which, together with the by-products rum and molasses, constitutes about three-fourths of the exports. Other products are gold, rice, balata, timber, and cattle. The country is fairly healthy, the death rate being about 35 per 1,000 (14.8 per 1,000 among whites).

Fic. 72.—Animals for the National Zoological Park awaiting shipment at Manaos, Brazil. Photograph by La Varre. He left the United States in June, 1919, and traveled directly to Manaos, Brazil, the jungle metropolis about 1,000 miles up the Amazon at the mouth of the Rio Negro. From Manaos he ascended the Rio Negro, by small steamer and launch, into Venezuela. He found much of interest, but no trace of the so-called “ cannibals ” of the region, or of anything savage, either beast or man. The natives, poor, half-breed rubber gatherers—Spanish, Portuguese, Negro, and Indian mixtures—treated him cordially and most hospitably, sharing their rude homes of thatch with him and giving him as much of their food as they could possibly spare.

Birds, on the contrary, were plentiful—among the con- spicuous species were toucans, curassows, macaws, and _ parrots. Mr. La Varre left the jungle in February, and arrived in the United States near the end of March, 1920. His collection of living animals, which he presented to the park, included a specimen of the rare black- headed ouakari monkey (Cacajo melanocephalus), a species never before represented in the collection.

Other animals in the La Varre collection are capuchin and squirrel monkeys, an ocelot, two margay cats, egrets, a scarlet ibis, and a number of parrots and paroquets. A large living specimen of the rare and curious matamata turtle, a gift to the park from Mr. A. T. S. Hore, of Manaos, was brought home with the lot. Another American resident of Manaos, Mr. Edward B. Kirk, also contributed some interesting birds, among which was a fine specimen of the very rare white-backed trumpeter (Psophia leucoptera) from the Rio Negro. NO. 6 SMITHSONIAN EXPLORATIONS, 1920 63 A second collection of living Neotropical animals was brought to the park by Dr. William M. Mann, of the Bureau of Entomology, United States Department of Agriculture, who visited Honduras in the spring of 1920. Dr. Mann’s duties in other lines naturally absorbed most of his time, but he succeeded in landing in good con- dition a number of valuable animals. His collection included pacas, agoutis, kinkajous, squirrels, a mantled howler monkey, and some reptiles, among which was a specimen of Rossignon’s snapping turtle, a species rarely taken by collectors. Other valuable animals were collected and presented to the park by Hon. Henry D. Baker, American Consul at Trinidad, British West Indies, and by Mr. Isaac Ellison, of Singapore, Straits Settlements. Mr. Ellison succeeded in landing and placing in the park a thrifty young male orang-utan, three years old. This is one of the most interesting and valuable gifts received in many years. The animal has now become thoroughly adapted to his new home and promises to become .a most unusually attractive addition to the collection. The National Zoological Park also shared in the large collection of African animals collected and brought to America for the New York Zoological Society by Mr. A. K. Haagner, director of the National Zoological Gardens at Pretoria, South Africa. Included in the lot received at Washington are a lechwe antelope and a specimen of the Rhodesian baboon, recently discovered and described by Mr. Haagner. ANTHROPOLOGICAL EXPEDITION TO THE FAR EAST Under the auspices of the Smithsonian Institution and in connec- tion with the Rockefeller Foundation and the Peking Union Medical -College, Dr. Ales Hrdli¢ka made an extensive trip to the Far East during the first half of 1920. The objects of this trip were continua- tion of the studies relating to the origin of the American aborigines ; examination of the oldest skeletal and other human remains in Japan ; the furthering of the interests of physical and medical anthropology in China; and a personal visit to the rapidly disappearing full-blooded Hawaiians. The countries visited included Japan, Korea, Manchuria, northern China, the boundary of southern Mongolia, and the islands of Oahu and Hawaii in the Hawaiian Archipelago. In Japan especial attention was given on one hand to the physical characteristics of the people, and on the other to the prehistoric anthropological collections. The latter have by now assumed con- siderable importance. They are deposited in the universities and medical schools of Tokio, Kyoto, Sendai, Osaka, and Kumamoto, 64 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. Se Fic. 77—Average types of Japanese children.

The Koreans are a modern race of mound builders. The country is full of archeological remains, including some big mounds and dolmens, and deserves much closer scientific atten- tion than it has so far received. Fic. 80 —A Korean Hamlet. From a few houses to large villages, they cluster in the nooks of the hills like mushrooms. The Manchus and the northern Chinese, particularly those of the Chihli Province, are for the most part tall, well-built people, quite different in bearing and even in physiognomy from the southern Chinese, though there is no sharp delimitation. They, too, present a fruitful field for detailed anthropological investigation. The southern or inner Mongolians were found to be a rather mixed lot, more so than the northern Mongolians who were visited by Dr. Hrdlicka in t912. A series of photographs was secured here as well as in Korea and Japan. In Japan, through the kind help of Dr. Tsunawo Araki, there was obtained a large collection of portraits 68 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOLi72 of Japanese children, while the Tokyo Dental College, through the good offices of Professor Mitsuru Okada, contributed several hun- dreds of portraits of its students. China, for the anthropologist and archeologist, is one vast open museum, in which something of absorbing interest 1s met with at almost every step. In addition the people, and particularly the students in colleges, impress one with their native abilities.

(See Smithsonian Explorations for 1917.) The whole work, now concluded, presents a good illustration of the practical value of anthropology in certain directions. The results are outlined in the following extracts from a letter to the Institution from Mr. R. C. Bell, Special Assistant to the Attorney General : The Department of Justice in 1910 instituted approximately 1500 suits in the United States Court for the District of Minnesota involving Indian lands. This litigation to January, 1916, has cost the government a very large sum and little had been accomplished. The blood status of the Indians became the determining factor and it was ascertained that all the available evidence (principally testimony as to genealogy) on this issue was found unreliable and always unsatisfactory. Consequently, the Department of Justice, in the spring of 1916, procured the services of Dr. Hrdlicka to make a physical examination of the Indians and report his conclusions as to their status. The doctor spent more than three months in this work and examined approximately 800 individuals. The Department of Justice, the Department of the Interior, and counsel for the defendants agreed to accept his findings as a basis for settlement, and the litigation now has been terminated, resulting in the recovery of more than $1,000,000 in land and money for the Indians; besides, the cost of the work since 1916 has been insignificant in comparison to the cost prior to that time. Furthermore, a commission was created by an Act of Congress to make a roll of the allottees of the White Earth Reservation. The law required, in addition to much other information, that the blood status of the Indians be given. This roll, which affects the title to approximately 725,0000 acres of land, has been completed; and the commission in preparing it followed the findings of the doctor. Only those thoroughly familiar with the situation can ‘appreciate the far-reaching importance of this work. FIELD-WORK ON THE MESA VERDE NATIONAL PARK The Chief of the Bureau of American Ethnology, Dr. J. Walter Fewkes, continued his field-work on the Mesa Verde National Park, Colorado, during June, August, and September, 1920, in cooperation with the National Park Service of the Department of the Interior. Excavation and repair work was done on the Fire Temple Group and Oak Tree House, ruins in Fewkes Canyon and at Cedar Tree Tower, situated about a mile north of Spruce Tree House, leading to im- portant contributions to our knowledge of the culture of cliff dwellers. He was ably assisted in this work by Mr. J. A. Jeancon, who made the originals of the ground plans of the Fire Temple Group and Cedar Tree Tower here published.

The most important discovery of the past season was the determina- tion by excavation that a large cliff house was not a dwelling, but specialized for some communal purpose. This ruin (fig. 98) was devoted to fire worship, a cult which up to this year, although sus- pected, had not been demonstrated as existing among cliff dwellers— at least no specialized building for that function had been recognized. In 1915 there was discovered on the promontory opposite Cliff Palace a building with semicircular ground plan that was interpreted . sei Fic. 96.—Western end of Fire Temple Court, half excavated.

While work on it was in progress a reconnoissance was made of cliff houses situated in the canyon below, to one of which was given the name Painted House. Like Sun Temple, it was suspected of having also been dedicated to some religious cult of the cliff dwellers, but its true significance was not apparent until the spade of the archeologist last season verified this suspicion and revealed its true purpose. Painted House, upon excavation, proved to be one of the most exceptional cliff ruins yet recognized in the Southwest. The results of the exca- vation have led Dr. Fewkes to designate it Fire Temple, and by No. 6 SMITHSONIAN EXPLORATIONS, 1920 81 implication to regard it a temple of the eternal fire. Attention should be called to the importance of the discovery that the cliff dwellers had a New Fire Cult and possibly that rites of new fire and conserva- tion of the same existed among prehistoric people of the Mesa Verde. The rites of kindling the new fire among the descendants of the cliff dwellers, as the Hopi, occur in July and November and are known as the Lesser and Greater fire ceremonials. The act in both is performed by means of a fire stick or drill made to rotate in a Bae Fic. 97.—Eastern end of Fire Temple Court. Photograph by G. L. Beam.

Probably it is to the Lesser Fire ceremony at the East Mesa of the Hopi that we should look for the nearest survival of the cliff dweller’s rite, as in it we find the personation of a phallic being, Kokopelli, whose picture was well preserved up to a few years ago on the wall of the secret chamber of the Fire Temple where fire was created. This Lesser New Fire, called Sumykoli, is celebrated by a fraternity of fire priests, now extinct, known as the Yaya priesthood. The Yaya priest at Hopi carries in his hand during this ceremony a rattle of 72 VOL.

Two of these, now in the museum of the Brooklyn Institute, were found in a cliff dwelling in the Chelly Canyon, which seems to indicate that there formerly existed among the cliff dwellers of that canyon a fire priesthood like the Hopi Yaya. As the cliff dwellers of Chelly Canyon and those of the Mesa Verde were closely related it is a fair conclusion that the latter also had a well-developed New Fire Cult, and possibly a Yaya priesthood. The masonry of Fire Temple points to an early epoch in the evolu- tion of the Mesa Verde culture, possibly one contemporary with the Fic. 101—Western end of Fire Temple Court. Photograph by G. L.

Architectural features that Fire Temple shares with Sun Temple may be interpreted by the close relationship of fire and sun cults among the cliff dwellers. Earth Lodge A, exca- vated in 1919, is the ancient type in the evolution of buildings on the mesa antedating stone walls, and there are evidences of successive stages illustrating cultural epochs from the crude Earth Lodge A, which the earliest colonists constructed, to those of horizontal ma- NO. 6 SMITHSONIAN EXPLORATIONS, 1920 85 sonry (fig. 108), the highest products of the mason’s craft in pre- historic North America. This evolution may have occurred on the area now reserved as a national park, but was not limited to it. After the abandonment of Fire Temple and the desertion of build- ings of the culminating epoch that followed, people of like culture may have still inhabited the great pueblos at Aztec and in the Chaco. But these in time also succumbed and were deserted before the arrival of the white man. Their descendants were amalgamated with nomadic or non-pueblo peoples and their survivors still inhabit the modern Fic. 102.—Bins for grinding corn in upper cave of Fire Temple House.

The Hopi, Zufii, and modern Rio Grande pueblos have no specialized buildings like Sun Temple nor Fire Temple for sun or fire cults, although they have ceremonial rooms where they formerly kindled the new fire annually. They no longer conserve the fire in this room, but there are legends that they did so in former times, pointing to a remote cultural connection between the cliff dwellers and their modern survivors, the Pueblos. 86 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 The general form and arrangement of rooms at the east and west ends of the central court of Fire Temple differ from any cliff ruin or pueblo in the Southwest. Significant facts show that the building (fig. 97) 1s unique, as will readily appear from the following state- ments. Excavations in other cliff houses of the same size reveal household utensils, as pottery, and other domiciliary objects. No cooking places, grinding bins, or household implements were found in the extensive work at Fire Temple. Moreover, every cliff house of size on the Mesa Verde has one or more specialized gener- Fic. 103 Oak Tree House from Sun Point Road. Photograph by G. L. Beam. Courtesy of the Denver and Rio Grande Railroad. ally circular subterranean rooms for ceremonies. There were no kivas in Fire Temple. But the one exceptional positive feature in this ruin that separates it widely from the cliff dwelling is stronger than these negative evidences. In no cliff house, and indeed in no pueblo, do we find a similar large circular fire pit filled with ashes in the center of a rectangular court. This structure would seem to be the key to the meaning of the whole building. That great fires were once built in this fireplace, as the abundant ashes indicate, no one can doubt. This fireplace is too large for an oven for culinary purposes and although we know that the cliff people sometimes cremated the dead the absence of calcined human bones would disprove the theory that NO. 6 SMITHSONIAN EXPLORATIONS, 1920 87 it was used as a crematory. A natural conclusion would be that it was constructed for ceremonies connected with fire. The significance of the two low-walled rectangular enclosures one on each side of the central fire pit, is unknown. Each was par- tially filled with soil and ashes when excavated and it is suggestive to record that the stratum of earth above them as well as the whole surface of the hardened floor of the court was filled or covered with charcoal and burnt brush. Great fires must have raged over the Fic. 104—Cedar Tree Tower before excavation. Photograph by JeeAs seancom: whole court in addition to that in the fireplace, after the temple was deserted. We find several other facts that fit in very well with the interpreta- tion that this building was a fire temple. On the east and west ends of the court (figs. 97, 101) there are banquettes, the former evidently seats for those who watched the ceremonial performance in the court. There are niches in the rear wall where possibly sacred objects may have been placed; a wall of the cliff bears triangles and zig-zag paint- ings, symbols of sex life ; but, most important of all, on the wall of one of the rooms at the west end of the court there are paintings in red, 88 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 one of which, now erased, represented a phallic being still associated with New Fire ceremonies among the Hopi, while others represent fire itself. At the New Fire ceremony among the Hopi one of the four fraternities that celebrate it is the order of Horn Priests, who wear on their heads imitations of the horns of mountain sheep. A large number of paintings of mountain sheep cover the walls of the west room of Fire Temple where fire was supposed to be kindled. The massive walled buildings at the east and west (fig. 94) ends of the court formerly reached to the roof of the cave, and although two stories high no wooden beams for flooring occur in their con- ee phe, e's We! re ACA oo 2 Fic. 105—Cedar Tree Tower after excavation.

On the white plastering, which is well preserved, there are numerous figures in red, mostly triangles and symbols of lightning ; female and male symbols similar to those in sacred rooms. Just west of Fire Temple there is a group of rooms from which utensils were excavated. In the floor of one of these rooms is a vertical shaft which opens outside the house walls like a ventilator. The former use of this structure is unknown. Although Fire Temple was not inhabited there were undoubted dwellings nearby. A hundred feet east of it there are two low caves, one above the other, in which may have lived those who once made NO. 6 SMITHSONIAN EXPLORATIONS, 1920 89 { 00m Pit { EXTENSION \ 1 UNDER CAP ROCKS aa x o'12345678910 ea SCALE oF FEET: RETAINING WALL Fic. 106.—Below, Cedar Tree Tower and kiva; above, ground plan of Cedar Tree Tower and kiva.

Dr. Fewkes has called the ruin (fig. 98) situ- ated in these caves the Fire Temple House and supposes it was the habitation of the fire priests and their familzes. The rooms in the lower cave were fitted for habitation, and it had two, possibly three, circular ceremonial rooms ; but the upper cave (fig. 99) is destitute of kivas. The large rooms of the upper house (fig. 100a) may have been granaries for storage of provisions, although possibly some of its rooms were inhabited. In the rear of the large rooms identified as granaries was found a small room with a well-preserved human skeleton accompanied with mortuary pottery. One of these mortuary offerings is a fine mug made of black and white ware beautifully dec- orated; a specimen worthy of exhibition with the best in any mu- seum. In the rear of the cave were three fine grinding bins (fig. 102), with metates still in place. The upper house 1s now approached from the lower by foot-holes in the cliff and a ladder shown in the illustration. Evidences of a secondary occupation of kivas in the lower house appear in double walls and those of crude masonry without mortar, forming a rec- tangular room built diagonally across the room. The plastering on the rear walls of the lower house is particularly well preserved, but there are very few rooms in addition to the kivas. One of the kivas has in place of a deflector and ventilator shaft a small rectangular trench enclosed by a well-made wall, as in Sun Temple. Work was done on the large cliff ruin, Oak Tree House (fig. 103), on the trail an eighth of a mile east of Fire Temple Group. Three new kivas were excavated to their floors and the walls repaired, add- ing to the four already known. No signs of these buried kivas were visible when work began. All these kivas show fine masonry ; after the most easterly had been used as a sanctuary for a time it was abandoned and five well-preserved grinding bins were set in the floor so as almost to conceal it. The upright slabs of stone and metates of these structures were reset, showing fine examples of these prehistoric mills. Many other novel features were brought to light in the exca- vation of Oak Tree House, which may be regarded as one of the most instructive ruins of the park. One of the exceptional features of Oak Tree House is a fragment of a circular wall in the rear of the cave, made of willow and other sticks set in mortar, like what is called “ stick and adobe ” construction in other regions. The ground plan of one of the kivas is semicircular and shows a rectangular room on the straight side communicating with the cham- ber by means of two passageways. The ventilator opens directly into this room, whose function 1s unknown. NO. 6 SMITHSONIAN EXPLORATIONS, 1920 gli In one of the grinding bins there was excavated a bundle of grass, Koeleria cristata, of exactly the same form as the brushes with which Hopi maidens sweep their metates after grinding meal; one more resemblance between cliff dweller and Hopi customs. In his classic on the “ Cliff Dwellers of the Mesa Verde,” Baron G. Nordenskiold figured and described a nameless ruin designated a tower (fig. 104), situated in the cedars about a mile north of Spruce Tree House. To this ruin the author has given the name Cedar Tree Fic. 107.—Section of floor of Cedar Tree Tower, showing ceremonial opening. Photograph by J. A. Jeancon. Tower, on account of an ancient cedar tree (fig. 105) hanging over the top of the north wall. Nordenskiold closes his brief description with the remark, ‘‘ Perhaps it should be regarded a religious building.” The desirability of testing this surmise of the talented Swede led the author, in August, 1920, to excavate this tower and the area about its base, which led to the discovery that although it appeared to stand alone there were two subterranean rooms connected with its base situated on the west and south sides. The larger of these rooms (fig. 106) had all the structural features of a typical kiva of a Mesa Verde cliff dwelling. This subterranean structure, its floor excavated Q2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 in solid rock, was circular with pedestals for supports of a roof, the beams of which were absent, and had a central fire hole, ventilator, and deflector.

In the middle of the solid rock floor of the tower which served as the foundation of the tower walls a circular hole or sipapi (fig. 107), symbolic of the entrance to the underworld, had been drilled, affording evidence that the tower was used for cere- monials, A distant view down Soda Canyon may be had from the top of the tower, although it is situated some distance from the rim of the mesa and shut in by a dense growth of cedars and pinyons. An automobile road constructed around Cedar Tree Tower was continued through the cedars to join the Mancos road. Several ladders were placed in position and a trail opened down the steep wall of Soda Canyon from Cedar Tree Tower to Painted Kiva House, an instructive cliff dwelling about a quarter of a mile away, formerly practically inaccessible. To the west of the Mancos road about the same distance from Spruce Tree House as Cedar Tree Tower there is another tower of the same type, but with walls of adjacent rooms projecting above ground. Several other similar towers have been reported on the mesa, in the Mancos, McElmo, and Hovenweep Can- yons, and elsewhere. The relation of a tower to kivas and other buildings of Square Tower House is shown in figure 108. A preliminary examination was made of the ruin at Aztec Springs now called Yucca House National Monument, in the Montezuma Valley, with a view to future excavation and repair of this important site. As no satisfactory photograph of this ruin has ever been pub- lished a view of the Lower House of this ruin taken in 1874 by W. H. Jackson is by his permission given in figure 109. It is planned to begin work on the Lower House of this great ruin in the spring Or 192% FIELD-WORK AMONG THE HOPI INDIANS Dr. Walter Hough, curator of ethnology, U. S. National Museum, spent the month of June among the Hopi Indians of Arizona, a tribe with which he has been associated for 25 years. At present some of the Hopi tribes are making rapid progress toward assimilating the culture of the white man, while others; though becoming more and more affected, show changes to a lesser degree. As these changes have taken place through peaceful assimilation and were not forced by war or other disruptive agency they present an interesting field for ethnological research on normal modifications of social struc- tures due to contacts. Some notes on this subject are appended. MATERIAL WELFARE The Hopi have prospered during the last quarter of a century. From the period when they knew almost nothing of money the Hopi No. 6 SMITHSONIAN EXPLORATIONS, 1920 95 have advanced to a complete familiarity with United States currency. Purchases can be paid for with check. Some of the more advanced have bank accounts. The Hopi were always acquisitive and frugal, and their habits have put them in a rather good financial condition. Their agricultural products have had a better market and the prices are less subject to the former fixed low valuations of the local trader. SoctaL CHANGES The most effective cause of social changes was the enforced atten- dance of children at government schools and the sending of children to distant Indian schools. Causing considerable friction at first, this has now been accepted in most cases as advantageous. A result not prevised is the weakening of the clan discipline whose former regulative authority was silent but powerful. The weakening of this authority produced much laxity for a time and it was found necessary to appoint policemen and a “ judge.” The government found it necessary to send away girls not noticeably under parental discipline to schools until they should become discreet. This measure was quite opportune and had a beneficial effect. Decay oF NATIVE CEREMONIES In this connection there is ensuing a rapid decay of native cere- monials. The heaviest loss to the native cult is felt by the death of the old men of a former generation. Very shortly there will be no one of the tribe who has not had training in school and more and more of these will evade the call of the native religion. Some fraternities have suspended operation and others are very weak. Notably the woman’s harvest ceremony at Walpi has passed out and the Snake Society there is about to discontinue. CHRISTIANIZATION Missions to the Hopi were carried on from time to time during a period of several hundred years without appreciable results. When the disintegration due to government control had progressed mis- sionary efforts began to bear fruit. The Baptist mission at Polacca has a stone church and a consider- able and growing number of converts. Other branches of this mission are doing well. A slight cleavage is observed between the Christians and non- Christians but no friction. The Hopi are agreed to let things work out as they will. 96 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 ARCHEOLOGICAL INVESTIGATIONS IN UTAH, ARIZONA, AND NEW MEXICO During May and early June, 1920, Neil M. Judd, curator of Ameri- can archeology, United States National Museum, continued his arch- eological reconnoissance of the arid region north of the Rio Colo- rado, Arizona, in behalf of the Bureau of American Ethnology.

Exposed pueblo ruins bordering the east rim of Pariah Plateau and overlooking the Painted Desert proved more numerous than was anticipated. In size, in arrangement of rooms and in the quality of their masonry these ancient dwellings are superior to those seen elsewhere in northwestern Arizona; likewise, potsherds examined at each site exhibit greater perfection of form and a higher decorative technique. These two factors—architectural Fic. 113.—Part of a cliff village in a cave on the east side of Cottonwood Canyon, near Kanab, Utah.

Following his researches for the Bureau of American Ethnology, Mr. Judd proceeded to New Mexico as director of an archeologic reconnoissance of the Chaco Canyon National Monument. This sur- vey was conducted under the auspices of the National Geographic Society and had for its prime object close examination of the aboriginal remains in the above monument with a view toward selec- NO. 6 SMITHSONIAN EXPLORATIONS, 1920 99 tion of a possible site for exhaustive investigation and permanent repair. The Chaco Canyon National Monument was created by presi- dential proclamation March 11, 1907, and includes 18 major ruins of very great significance in the study of ancient Pueblo life.

The beauty and technique of such specimens warrant the belief that these canyon dwellers had reached a plane of esthetic as well as social development not surpassed elsewhere in the Southwest. Although the 18 major ruins constitute the main feature of this national monument there are, in addition, hundreds of “ small house” remains scattered throughout the entire Chaco Canyon dis- trict. In culture as well as in architecture these lesser dwellings were closely allied to the larger structures.

Certain it is that comprehensive investiga- tions in the Chaco Canyon drainage will add largely to present knowl- edge concerning the prehistoric pueblo peoples of the southwestern desert country. MUSIC OF THE PAPAGO AND PAWNEE In February, 1920, Miss Densmore went to the Papago Reserva- tion in southwestern Arizona to continue her study of Indian music for the Bureau of American Ethnology, residing for more than four NO. 6 SMITHSONIAN EXPLORATIONS, 1920 103 weeks at a government station called San Xavier Mission. The Papago tribe was selected partly because of its desert habitat (fig. 120), the intention being to compare the phonographic records of Papago songs with those of Arabian songs obtained from Arabs who were temporarily in Washington, D. C. (Subsequent results proved the value of this comparison.) According to the last census there are 7,465 Papago Indians on the reservation, but not one “ mixed-blood ” family. It is said further that there has never been any intermarriage between this tribe and Mexicans or Spanish. Their manner of life is becoming modified, but many primitive customs remain and were observed. A primitive burial place was found by Miss Densmore. acini Fic. 120.—Habitat of Papag o Indians. (Photograph by Miss Densmore.) These burial places were constructive on the side of a mountain and consisted of low walls of rocks, roofed with timber and tightly closed with stones. Bodies were removed after a time to make room for other burials. A skull and a few bones remained in the tomb exam- ined. The subjects studied were: (1) Songs used in treating diseases caused by spirits of dead Apaches and Papago; (2) songs connected with the “ purification ” of returned warriors who had killed Apaches, and (3) songs connected with dreams, games, and dances. Musical instruments formed a subject of special investigation. A native flageolet was obtained (fig. 12) together with the tradition concerning its origin. The music of this instrument was phonographically recorded and has been transcribed. The Papago beat upon an over- 104 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Fic. 121.—Papago playing on native flageolet. - NO. 6 SMITHSONIAN EXPLORATIONS, 1920 105 turned basket instead of a drum, striking the basket with the palms of one or both hands. “ Rasping sticks” are sometimes used with such a basket, as shown in figure 122. Fic. 122.—Papago and native musical instruments. After a brief stay in Phoenix, Arizona, Miss Densmore went to Camp McDowell (formerly Fort McDowell) and was present at a 106 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 gathering of Mohave Apaches, explaining her work and securing their consent to record songs on a subsequent visit. The adobe build- ings of the old fort are in ruins, but a few of the smaller and more substantial buildings remain. From Arizona Miss Densmore went to Pawnee, Oklahoma, arriving April 12, a few days before the Morning Star Ceremony. This is one of the most important ceremonies of the year as it is held for the purpose of securing good crops. At this time the “ Morning Star Bundle” is opened and its contents displayed for several hours, while the proper rituals are sung. Miss Densmore was allowed to enter the lodge for a brief time and to view the sacred articles (it is said Fic. 123.—Pawnee lodge of Morning Star Ceremony, (Photograph by Miss Densmore.) only one other white person has been accorded this privilege). Dur- ing the remainder oi the ceremony, which lasted many hours, she stayed outside the lodge (fig. 123) and make manuscript notes of the songs. An approach to two-part music, heard at this time, had not been previously observed. While at Pawnee a sufficient number of songs was recorded to complete the musical study of that tribe. In November, 1920, Miss Densmore returned to Arizona to resume work among the Papago. The principal work was done at Vomari, a point near the Mexican border and 80 miles from the railroad. Inter- esting material was collected also at Sells, formerly known as Indian Oasis. Among the subjects studied were: (1) The Papago expedi- tions to the Gulf of California for salt and for “ medicine power,” No. 6 SMITHSONIAN EXPLORATIONS, 1920 107 each sort of expedition having its songs; and (2) the rain-making ceremonies, including the manufacture of tizwin. In connection with the latter a visit was made to Santa Rosa, at the extreme north of the reservation, where a tizwin camp and lodge were photographed. A specimen of the cactus syrup used in making tizwin was obtained, as well as a large basket which had been used in serving this wine. Many sites of legendary or geographic interest were photographed, Miss Densmore travelling more than 360 miles by auto on this trip. The most important result of this expedition was the hearing of a form of three-part music at a Papago dance. This was said to be a native musical custom. So near an approach to polyphonic music has not been hitherto observed by Miss Densmore and the subject will receive further investigation. OZARK CAVES AND MOUNDS IN MISSOURI During the summer of 1919 the work of cave exploration in the Ozark region was continued by Mr. Gerard Fowke, for the Bureau of American Ethnology. Almost his entire time was given to a thorough examination of two large caves in Pulaski County. The first, known as Miller’s cave, is three miles northeast of Big Piney postoffice. The opening is in the vertical face of a high cliff fronting Big Piney River, with a steep talus slope beginning 30 feet below the floor of the cave and extending to the water’s edge. The perpen- dicular wall below, with a projecting ledge which forms the roof, prevents a direct entrance, and the interior can be approached only through another cave whose opening is in a ravine near by. A narrow passage, barely large enough to admit a man in a crawling or crouch- ing position, connects the two, and it is only through this that access can be gained to the main cave. The inmates were absolutely safe from molestation, as one man could defend this opening against any number. A little stream flowing along the foot of the east side of the cavern ensured a supply of water at all times: game was plentiful in the neighborhood: the river abounded in fish; and fertile, level bottom lands, easily cultivated, on either side of the stream furnished much corn and other farm products. A ditch and enbankment across an isthmus guarded a peninsula on the opposite side of the river, and on both sides low house mounds and abundant debris furnished proof of two large village sites. Whether there was any connection between the villages and the cave dwellers cannot be determined. A bed of clean, pure ashes whose depth ranged from 3 to 64 feet, according to the irregularities of the clay, was found in the cave 108 SMITHSONIAN MISCELLANEOUS. COLLECTIONS VOL. 72 reaching from wall to wall, a width varying from 45 to 70 feet. This bed was so loose as to be almost like a snow bank; but for the most part they were as compact as if much trampled over while wet. When solidly packed, the mass would measure fully 800 cubic yards in volume; but when loosened by excavation, 200 cubic yards more. All the wood had to be carried from either the top or the bottom of the hill, which is about 400 feet high, and passed through the small opening from the other cave. It is safe to say no more fuel would be used than was strictly necessary. When it is considered how little fire is requisite for the needs of an Indian household, and that the limited space suitable for residence would not provide sufficient room for more than half a dozen families at a time, it is quite clear that this amount of ashes meant a very long occupancy. [ven with continuous habitation, several centuries would be required for such a quantity to accumulate; and if residence was desultory and intermittent, as is customary with roving or hunting tribes, or if it was only a winter home for some of those living in the villages mentioned, the period would be greatly lengthened. Yet the remains found in these ashes were of the same character from top to bottom. The artificial objects found numbered about 75 mortars, more than 200 pestles, hundreds of flint knives or spear heads, numerous implements of bone, antler, and shell; quantities of crude pottery fragments, a few tomahawks, and two pipes. While the many mortars and pestles indicate much use of grain, seeds, and nuts, at the same time the great amount of mammal, bird, and fish bones showed that a large part of their sustenance was derived from animal food. Of more than 20 skeletons found in various stages of decay, only two were of aged individuals, most being remains of children or young persons. The skulls were of low type. Not an ornament of any sort was found except a few rude ones of bone or shell. Some of the human bones, mostly those of children, were charred and broken, and mingled with the debris of food animals and ashes as if the flesh had been used for food, and the broken bones thrown aside with the refuse. There was no evidence of the crema- tion of bodies ; the condition of these bones points to the practice of cannibalism. The second cave explored is situated a mile south of Waynesville, on land belonging to Dr. J. W. Sell, and was probably a temporary camping place. Its opening is on a hillside facing Roubidoux creek, and is easily accessible from either the top or the bottom of the hill. A few rods back from the entrance, water stands on the floor through- out the year: so that only the front part of the cave was used for shelter. At the entrance is a pile of earth washed from the sloping NO. 6 SMITHSONIAN EXPLORATIONS, 1920 10g surface of the hill above, over the ledge that forms the roof. This accumulation spreads for 50 feet into the cave, but not so far on the outside, because there it washes down the slope. From its surface to the clay floor on which it rested the greatest depth was a few inches over six feet. From top to bottom there was found in this cave the ordinary debris of an Indian campfire. Buried at various depths here and there, in the portion within the cave were 14 human skele- tons, most of them so decayed that only a few fragments were remain- ing. They are of persons of various ages; some of the skulls were low, small, and flat. A long period of occupancy is indicated by the conditions here as at Miller’s cave. While the amount of earth heaped in front of the cave does not seem large, yet it all has come from a space not exceed- ing 6,000 square feet in area and most of this is bare rock with humus of decayed vegetation existing only in the crevices or on the few flat surfaces. All the other water from the hill runs to the slopes and does not reach the cave. A violent storm passed over the region soon after the work was concluded, in which 12 inches of rain fell in three days, yet not more than a wheelbarrow load of soil was washed down over the roof to the pile already there. It is evident that cen- turies would be required to build up the mass, throughout which these traces of man’s presence are scattered promiscuously. During all the period these caves were in use no improvement took place in the fabrication of stone implements or pottery. Specimens found nearest the top of the ashes or dirt could not be distinguished from those of the same class from the rock or clay floors. The inhabi- tants remained in the same plane of culture. The thousands of small mounds extending southward from the upper swamp region of Missouri have long been a puzzle to arche- ologists and until recently it has been supposed that in this state they are confined to the southeastern portion: but in the course of Mr. Fowke’s field-work they have been found to extend to the north and west as well. Groups of them have been located in Oregon, Dent, Phelps, Pulaski, Osage, and Morgan counties, the latter along the Benton County line. Their purpose has not yet been determined, although Thoburn’s hypothesis that they are due to the Pawnees, whose line of migration was through the area in which they occur, and are the remains of earth-covered houses, seems the most tenable yet advanced. This theory implies that when this tribe passed beyond the region in which suitable timber for supporting the weight of the earth, and also earth adapted to such use, could be procured, they were compelled to substitute for them small poles overlaid with grass. 8 110 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Comparison with the typical modern Pawnee earth lodge, a photo- graph of which Miss Densmore published in her account of field- work for 1919, corroborates Thoburn’s interpretation of these Missouri mounds. ARCHEOLOGICAL RECONNOISSANCE IN HAWAII With an allotment from the Bureau of American Ethnology, Mr. Fowke spent the entire summer of 1920 in the Hawaiian Islands, making a careiul examination of all ancient works of whatever nature, that could be visited with the time and opportunities at his command. While there is abundant evidence everywhere that the old Hawaiian people were extremely industrious, using vast quantities of stone in Fic. 124.—Pawnee ceremonial earth lodge, exterior. Photograph by Miss Densmore. the construction of their temples, houses, garden enclosures, fish ponds, and taro terraces, there was nothing discoverable among all these remains which could be attributed to a prehistoric tribe, or to any other race than that found in possession when the islands were first known to the white man. The five principal islands were visited and explored as thoroughly as was possible in the circumstances. It was not practicable to ex- amine every feature of interest, where there is so much demanding attention; but at no place could there be discovered any indication which would seem to justify excavation with the expectation of un- NO. 6 SMITHSONIAN EXPLORATIONS, 1920 MEA EAE earthing beneath the top soil remains which might differ in general character from those on the surface. There being no difference between remains belonging to the historic period and those superficially showing evidence of great age, it is logical to conclude that when that branch of the Polynesian race, now known as Hawaiians, left their home in the distant South Seas and migrated to these islands, they found the territory without inhabitants ; and there is no reason what- ever for supposing that any people culturally different from the his- toric Hawauians had ever previously lived on the islands. FIELD-WORK AMONG THE FOX AND PLAINS CREE INDIANS Dr. Michelson, ethnologist of the Bureau of American Ethnology, began field-work among the Fox Indians at Tama, Iowa, about the Fic. 125——The dwelling in which the White Buffalo Dance of the Fox In- dians is held. The building is the typical “ bark” house used by the Fox in the summer and early fall. middle of June. His main purpose was to restore phonetically a text containing the autobiography of an Indian woman written in the cur- rent syllabary which he had obtained in the summer of 1918, to correct the translation where there was need, to elucidate some ethnological references contained in the text, to clear up some grammatical ob- scurities, and to work out the verbal stems so far as was feasible in the field. All this was successfully accomplished, and Dr. Michelson left for Saskatchewan in the latter part of July for a preliminary investigation of the Plains Cree. The results of this investiga- tion show that the Plains Cree are tall and have a cephalic index LIZ SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 .

The general grammatical prin- ciples which have been worked out for Fox apply also to Cree. In some respects Cree is more archaic than Fox, in others less so. Ethnologically the Plains Cree are about half way between more typical Indians of the Plains, such as the Blackfeet, and the Central Algonquins. An analysis of the myths and tales which cluster around the culture hero shows that we practically have the myths and tales of the culture heroes of the Blackfeet and Ojibwa combined. All this is just what one would expect from the geographical position of the Plains Cree. ARCHEOLOGICAL EXPLORATIONS IN TENNESSEE Mr. W. E. Myer, of Nashville, Tenn., spent September and October, 1920, making explorations for the Bureau of American Ethnology in the Cumberland Valley around Nashville. He dis- covered on the H. L. Gordon farm, one mile northeast of Brentwood, in Davidson County, the remains of an ancient Indian walled town. These were situated in a woodland and had never been disturbed by the plow. Their partial exploration brought to light some new and interesting details of the life of the inhabitants. Traces of 87 house circles and faint indications of several more could be made out. This town covered 11.2 acres and was surrounded by an earthen embank- ment which formerly supported a palisaded wall, equipped with circular towers every 55 feet. The ancient inhabitants, for some unknown reason, had deserted .this village and the site had never afterward been occupied or dis- turbed. The deserted structures had gradually fallen down and the remains slowly buried under from 10 to 14 inches of earthmold. In some of these circles portions of beautiful, smooth, hard-packed, glossy-black floors were found. In the centers were the ancient fire- bowls, yet filled with the ashes of the last fires kindled in these homes before their owners left them forever. Near these fire-bowls often could be seen the metates, mullers and other household utensils, just as left the last time used. Underneath the floors were the stone slab graves of the little children, one of which is shown in figures 128 and 120. A level open space was found near the center of the town and on the western side of this plaza was a low flat-top mound that had originally supported some important building. Adjoining this mound 114 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 on the west was an earth circle which probably outlined the ruins of the town house. At the center of this sacred structure, on the unique black glossy floor, an ancient altar (fig. 130) was found. It was still filled with the pure white ashes of what had once been the sacred fire. Fic. 128.—Child’s grave after removal of infiltrated soil, before disturbing mortuary vessels. This altar was carefully preserved and is now in the Bureau of Ethnology.

At the iD 3S No. 6 SMITHSONIAN EXPLORATIONS, 19 115 request of many citizens of Tennessee Mr. Myer named this site the Fewkes Group, in honor of Dr. J.

The later band used rectangular stone slab graves with the body extended full length on its back. 116 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 The Fewkes Group consists of four mounds, one on each of the four sides of a level plaza, the traces of about a dozen house circles, and a small remnant of what was once a considerable stone slab cemetery. Fic. 130.—Altar. Mound No. 2 on the map is a low oval mound situated on the western side of the plaza. The site of this mound had been lived upon for some time before any mound was raised. At last the mound was commenced and raised to a height of three feet and a building for domestic purposes erected thereon. This building was later torn down and then the mound was raised three feet higher. The mound was again used for domestic purposes for a period. Then a town house NO. 6 SMITHSONIAN EXPLORATIONS, 1920 WAVY), or sacred ceremonial house was built on it. This sacred building also had one of those rare, beautiful floors made of clay, smoothed, then hardened by fire, and finally covered with a coating which is yet black and glossy. In the center of the building, on this beautiful floor, an altar was found. It was similar to the altar shown in figure 130. This building had walls made of cane stalks with the leaves attached, which had been woven in and out between the upright posts which supported the roof. These canes may have had a coating of earth, though no trace of it could be found, and the walls also had a Fic. 131.—Mortuary vessel from child’s grave. covering of woven cane matting. In some way the building was destroyed by fire. Earth was thrown on the remains in time to smother its still glowing embers, which produced a large amount of powdery charcoal containing fragments of cane stalks with the leaves attached, and portions of the woven cane matting. After this sacred building was burned the mound was raised one and one-half feet or more in height. All trace of its last use has been destroyed by 85 years of cultivation. The low mound, No. 3, on the south side of the plaza, was a burial mound belonging to the first settlers. The mortuary vessel shown in figure 131 came from a hexagonal grave in this mound. 118 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Mound No. 1 on the north side of the plaza is 180 feet across the base and 25 feet high. It is the most conspicuous mound in the group. Lack of funds prevented its exploration. House circle No. 6 was one of the group of buildings, Nos. 6, 10, and 11, whose functions were doubtless closely interwoven. No. 6 contained in its center an altar or fire-bowl. There was evidence that this town had either been taken by an enemy and burned, or the ancient inhabitants, forced to flee, had burned their homes to prevent their falling into the hands of the invader.

No broken animal bones, pottery, fragments, or other evidences of untidiness littered the floor. The floor was of hard-packed clay and a fire-bowl was sunk in the center of the floor. At this fire-bowl a puzzling burial was unearthed. A child, about eight years of age, was buried by the side of the upright stone slab, with its head resting just within the extreme edge of the fire-bowl, whose rim had been cut away at this point to admit the top of the child’s head. The fire-bowl was found still filled with ashes, and although the ashes covered the top NO. 6 SMITHSONIAN EXPLORATIONS, 1920 I1g of the child’s head, the head showed not the faintest trace of the action of fire. The graves of two infants were also found in the floor of this house. At both the Gordon and the Fewkes groups every piece of bone and every fragment of pottery was carefully saved and location noted. These thousands of fragments will give a reliable record of the food animals and practically a complete list of all the sizes, colors and shapes of their domestic pottery. Both these sites, when explorations were completed, were accurately restored to their original shape for the benefit of coming generations. The interesting altars, fire-bowls, building post-holes, and vestiges of domestic life were carefully preserved, and again covered up so as to allow their future study. It is strongly urged by the citizens of Tennessee that the Fewkes Group be made a national monument. Mr. Myer discovered a great Indian fortress on the long, narrow point of land between the Harpeth and Cumberland rivers, at their junction, in Cheatham County, Tennessee. This fortress consists of a thin, double-faced bluff, about three-quarters of a mile in length, and only from 10 to 250 feet wide along its tall and narrow summit. It faces both rivers and has nearly perpendicular sides along its entire length on both streams. It can be scaled with very great difficulty and at only a few places. The Indians protected these few places of ascent with breastworks or mounds. This was a central place of refuge for a series of scattered Indian settlements extending about six miles up and five miles down the Cumberland River and about five miles up the Harpeth. The four pipes from this region are unlike any found elsewhere . in the valley, and probably the culture of the ancient people who used this fort was different from any other known at present in the Cum- berland Valley. Ona recent visit Dr. Fewkes examined the great unexplored mound group on Harpeth River at the mouth of Dog Creek, in Cheatham County. This group is the remains of one of the important pre- historic settlements east of the Mississippi. There is a great mound, with wide earthen platforms, capping a hill in the up-stream end of this settlement. A portion of the hill has been artificially shaped so as to give greater prominence to the works on top of it. Surrounding these works on the summit are the ruins of a large edifice and other important remains. This portion of the settlement covers about 40 acres and is said to be connected by an embankment with the remainder of the mounds in Mound Bottom, I20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 about two miles down the Harpeth.

Jeancon, special archeologist of the Bureau of American Ethnology, made a recon- noissance and conducted intensive archeological work at Taos, New Mexico. While it has been known for a long time that there was excellent archeological as well as ethnological material to be obtained in this valley, no archeological research has been done there before the present work in the summer of 1920. The great number and variety of sites seem to indicate a long period of occupancy of the region. These sites are well-defined small house groups, each indicating one, two, or more rooms. ‘There are also great communal groups as that at Bagley ranch and the Arroyo Hondo. The mounds are sometimes over 20 feet in height; the pottery sherds scattered over these sites range from the primitive black-and-white ware to what appears to be the so-called biscuit ware. A small pueblo ruin at Llano was selected for excavation and, while the yield of pottery was small, many interesting facts were obtained. The ruin is located on the south bank of the Little Rio Grande, one mile and a half from the plaza of Ranchos de Taos. Situated on the edge of a high mesa it commands a magnificent view of the country for miles around, excepting to the east, where the view is cut off by NO. 6 SMITHSONIAN EXPLORATIONS, 1920 121 the mountains. The fields which probably furnished the villagers well-watered agricultural areas are situated in the valley below. The excavation showed that there had been two occupations on the site. In several places the remains of earlier old walls show beneath the present walls, indicating that the first and second buildings had Fic. 134.—Ruin at Llano, Taos Valley. totally different ground plans. All of the walls (fig. 134) were made of a mixture of wood ash, small stones (about the size of pebbles ordi1- narily found in gravel), and adobe which when exposed to the air becomes very hard. The walls of the second occupation are not as well made as those of the first, but the floors of both resemble those of the older villages still inhabited, where the blood of animals was used to give them temper and polish. [22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 The general plan of the ruin recalls those of southwestern Colo- rado. The kiva at Llano (fig. 135) was completely surrounded with rooms and when the roof was intact its surface was a small plaza surrounded by the buildings of the main group. An evidence of the two occupations is that the more recent kiva was built inside the older, and the space between their walls had been filled in with rubbish. No roof timbers remained in the ruin, but there were in the kiva four upright posts upon which the former roof rested. In about the center of the kiva there was an excellent fireplace, and in the floor directly Fic. 135.—Kiva at Llano, Taos Valley. adjoining the fireplace a plastered pit (fig. 135), an unusual adjunct to the fireplace, the purpose of which is unknown. Between the fire- place and the pit is a stone slab, one foot high and about nine inches wide. The excavations brought to light a very small number of the undecorated sherds of white ware; the black-and-white pottery is unusually hard and fine, but the black or rather brownish-black ware used for cooking and storage is very soft. The forms of and designs on the black-and-white pottery strongly suggest the San Juan ware. During the month of May, 1920, Mr. Jeancon made a satisfactory reconnoissance in the country lying south and southwest of Dulce, 123 SMITHSONIAN EXPLORATIONS, 1920 NO. Fic, 136—Ruin in La Jara Canyon. Fic. 137.—Ruin in La Jara Canyon. 124 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 New Mexico. He found in Burns, La Jara and other canyons indi- cations of two periods of occupation evinced by the pottery which belongs to the old pre-Spanish black-and-white and the hard- coiled wares. The houses of the earlier period were “earth lodges” of a primitive type. The house remains point to the second occupation and are in many cases built on the tops of high masses of sandstone (fig. 136), and show the crudest workmanship. A common site for buildings is the edge of high points (fig. 137), along the terraced (natural) sides of the canyons. All of the later sites give ~ a Set Fic. 138.—Dulce Ruin. an impression that they were more or less defensive and _ hastily erected. Associated with these buildings are remains of metal objects, apparently of Spanish manufacture ; many of the beams in the houses plainly show the marks of metal tools. The pottery has a bluish-black color, closely resembling a modern vitrified brick, and is so hard that when struck it rings with a clear bell-like tone. The surface suggests old Hopi ware and the decorations are similar to the older Zuni and Acoma designs. The pottery and associate remains probably do not antedate the reconquest of the Southwest by the Spaniards in 1690. It is known that some of the pueblo people fled from the Spaniards at the time of NO. 6 SMITHSONIAN EXPLORATIONS, 1920 125 the great rebellion and took refuge in the mountains to the north. It is probable that further investigation will show that in this area the ruins ascribed to the second period were built and inhabited by refugees from Zuni and Acoma. ARCHEOLOGICAL EXPLORATIONS IN EASTERN TEXAS Archeological field-work was carried on in 1920 by the Bureau of American Ethnology in co-operation with the University of Texas under direction of Professor Pearce and Professor Engerrand. Several localities in Texas were visited and considerable intensive work done in the eastern part of the state. The region in eastern Texas to which most attention was given was in the vicinity of the little city of Athens in Henderson County. Judge A. B. Watkins of that city has long taken a keen interest in the history and archeology of the region and was of great help to Professor Pearce in his field-work. A number of aboriginal objects, complete specimens of pottery, clay pipes, conch-shell cores, fine arrowheads and human bones were obtained from an ancient burial ground two miles northeast of Frankston on the De Rossett Farm. One of the objects found was a “ turkey call” or whistle made from the drumstick of a turkey. This is identical with those used not many years ago by old white hunters on the frontier and Professor Pearce feels sure that the white man’s use of this device was borrowed from the Indian. Professor Pearce finds that the east Texas region contains numerous mounds, village sites and burial places, among which may be mentioned Nacogdoches, Panola, Bowie, Wood and other counties. Three interesting mounds on the Morrall Farm four miles east of Cherokee County were investigated. The highest of these mounds has an altitude of about 35 feet above the level valley or field in which they are all located and is about 80 feet across at the base. This mound is very steep and even now after long erosion its sides rise at an angle of 45°. Mound B is 180 feet long by 75 feet wide and rises only 15 feet above the general level. The other three mounds in the vicinity of Athens have been ploughed into and have no regularity in form. On the Quate tract east of De Rossett farms there are Indian mounds which were not regarded as very ancient. Several mounds situated in Harrison County on the farm of Mr. Lane Mitchell, of Marshall, were examined and remains of earth lodges with central fire pits were reached. These mounds are probably very ancient. 126 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Numerous other sites were explored, yielding a collection of pottery, stone implements and other objects, illustrating the life of the pre- historic aborigines of eastern Texas. Everything found implies that the Indians of this region lived in relatively settled villages, had considerable agriculture, made pottery extensively and of a high-grade, and were altogether in a considerably higher stage of culture than were those who occupied the prairies and plains.

The proportion of varie- gated crinoids is very much higher in the irregular than in the regular species because they are all from shallow water and it is in the shallow ‘ water that the colors of crinoids are best developed. From a mini- mum in the coldest regions the proportion of irregular flowers in- creases to a maximum in the tropics; from a minimum in the coldest water the irregular crinoids increase to a maximum in the tropical littoral. About three-quarters of all our blue, violet and purple flowers are irregular; since blue, violet and purple seem to be the most con- spicuous colors so far as insects are concerned a flower loses less in visibility by being of these colors than it would by being of other colors. Blue is only recorded from irregular crinoids, and violet and purple are much more common in irregular than in regular types, as a result of the occurrence of the former only in shallow water. In the crinoids the pigment is not confined to the exterior of the animal as in most active types, including the other echinoderms, but 34 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 occurs more or less generally distributed throughout the body just as pigment is distributed throughout the interior of many plants. The coloring matter of the crinoids is, in part at least, a lipochrome, and other lipochromes occur in a number of flowers just as indigo, occur- ring in many different plants, is also found in the Polyzoa and other animals, and just as cellulose or a very closely allied substance is found in the tunicates. Many flowers have a sweet and attractive odor, and certain crinoids (Tropiometra and others) also exhale a pleasant plum-like aroma, though this is not so marked as in the case of certain polyzoans (Flustra) ; as this pervades the whole animal it is perhaps better to compare these types with such plants as those of the families Menthaceze or Myricaceze, most of which are aromatic. But among the fixed animals these plants more nearly parallel the sponges in this respect, while the sharp principle pervading the cruciferous plants calls to mind the very acrid secretions found in the ccelenterates. Many plants, like nettles, have stinging hairs; in the crinoids the secretion from the glands connected with the hair-like papilla on the tentacles appears to possess stinging qualities. Just as cattle will not eat nettles, so the fishes carefully avoid the crinoids. The petals of certain flowers, as in the Hypericacee, are dotted with so-called glands containing excretory products and often arranged in regular rows. Along the ambulacral grooves in the ¢rinoids is a row of minute glandular bodies also containing excretory products. Similarity of habit and the resultant similarity or at least parallel- ism in the problems to be met have given rise to a very close corre- spondence in many features between the fixed and sessile animals and the plants, though the means by which this close correspondence has been attained differ very widely in the two classes of organisms. PARASITES AND COMMENSALS A very large number of organisms belonging to very diverse groups are found more or less associated with the crinoids. The relation between these types and the crinoid hosts runs by imperceptible gradations all the way from true parasitism, in which the organism feeds directly upon the body tissues or fluids of the host, to the most casual or even accidental association. The animals associated with the crinoids may be grouped as follows: I. True parasites—Animals which (1) live upon the tissues or body fluids of the crinoids and occur either (a) internally or (b) externally; (2) occur internally, though not feeding directly upon NO. 7 SEA-LILIES AND FEATHER-STARS—CLARK 35 the tissues of the host; or (3) while living externally upon the sur- face of the body and not feeding directly upon the tissues or fluids of the host are more or less permanently fixed in position and cause more or less extensive malformations, sometimes becoming encysted. This class includes a few “ worms,’ a number of myzostomes, a few crustaceans, and the parasitic gasteropods. Il. Semiparasitic commensals—Animals which feed upon minute organisms and have to a greater or lesser extent adopted the habit of sucking up the food particles from the streams flowing down the ambulacral grooves of the crinoid to the mouth, or of temporarily entering the digestive tube and feeding upon the contained matter. This class includes the polynoid and ophiuran parasites, most of the crustacea, and most of the myzostomes. III. Nonparasitic commensals—Animals which, while usually, or commonly, found living upon or among the crinoids lead an entirely independent existence and for the most part are found living under similar relations with other organisms. Here are included the foraminifera, sponges, corals, hydroids, polyzoa, barnacles, tunicates and Rhabdopleura, as well as certain shrimps. IV. Casual associates—Animals which normally occur hiding among, crawling over, or attached to other usually arborescent organ- isms (fig. 62) from which they may or may not derive nourishment, or which normally occur attached to any available support, and which occasionally stray among or upon, or attach themselves to, the crin- oids, but remain otherwise entirely independent of them. This class includes a vast number of organisms of very diverse types. _ As in the case of the other arborescent marine types, and in general among the animals that live by filtering the smaller plankton from the sea water, the crinoids are chiefly subject to indirect parasitism, that is to say, the creatures depending upon them for their existence appropriate the food particles which the crinoids have collected in the ambulacral grooves, or even which they have swallowed, instead of consuming the tissues or body fluids directly. Of the animals which derive a part or all of their nutriment from the body or from the efforts of the crinoids about 10 per cent are directly parasitic, and about 90 per cent are indirectly parasitic in varying degrees. Of the animals which are parasitic on the crinoids nearly all may be described as casual parasites, for they belong to genera or families other representatives of which are nonparasitic; that is to say, they are merely particular species which have found an easy existence in 36 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 preying upon the crinoids, though this mode of life has not induced any special modification of their structure. There is a curious and interesting correspondence between the relations of the fixed marine organisms (including the crinoids) and their parasites and commensals and those between parasitic and epi- phytic flowering plants and their hosts. The barnacles, most hydroids, polyzoans, etc., correspond very closely to the epiphytic plants, espe- cially those of the families Orchidaceze and Bromeliacee. Rhabdo- pleura and certain hydroids are quite vine-like in habit, ascending crinoid stems as vines do the trunks of trees. Most parasitic plants appropriate the unelaborated sap of the host and convert it to their own ends; most parasites of the fixed marine organisms in the same way appropriate the concentrated but undigested microplankton in or approaching the stomach of the host. On land most animals are parasitized by animals of an inferior organization; but among the fixed marine animals the parasites for the most part belong to a phylum with a superior organization and sometimes even to the same phylum (ccelenterates parasitic on ccelenterates, crustaceans parasitic on crustaceans, ophiurans parasitic on crinoids, etc.). The relations between the fixed marine animals and their parasites are thus more nearly the same as those between parasitic flowering plants and their hosts. On land the various animal groups are definitely parasitic or nonparasitic ; but many plant families, such as the Scrophulariacez, Santalacez, etc., and even many single genera, such as. Pedicularis, Melampyrum, Gerardia, etc., include both parasitic and nonparasitic species, just as do many families and genera, such as Synalpheus, Periclimenes, etc., occurring with the fixed marine animals. The three types of parasites which are of especial interest are the gasteropods (Stilifer, Stylina, Sabinella and Melanella), Enterog- nathus and the myzostomes (figs. 57, 58). The family Melanellide to which Stilifer, Stylina, Sabinella and Melanella belong includes species showing all gradations between free-living nonparasitic types and shell-less parasites living entirely within the body of the host. As parasites the Melanellidz occur only upon the echinoderms, in which group, however, they are found on species of all the classes. Most of the parasitic forms, including all of those occurring on the crinoids, are characterized by extraordinarily delicate shells. Some of the species are permanently fixed in one position on the body of the host, but others, including all those found upon the crinoids, appear to move about and to bore into different parts of the host. It is not a little curious that, apart from Melanella capensis and Stylina comatulicola, all the species parasitic on the NO. 7 SEA-LILIES AND FEATHER-STARS—CLARK a7 crinoids are always attached to the calyx plates, or to the cirrals, brachials and pinnulars instead of to the soft ventral integument. The curious copepod Enterognathus occurs only in crinoids, but the family to which it belongs is well known as a parasite (or com- mensal) of the tunicates, most of the species living in the branchial chamber of these animals. The myzostomes form a group of very highly specialized polychzete annelids and are the chief parasites of the crinoids, to which animals they are almost exclusively confined. On the crinoids they are, with one possible exception, always ectoparasitic, though they may form soft or calcified cysts within which they are almost completely isolated from the outer world. An organism, possibly a myzostome, has been reported in the ovarian cavity of Notocrinus virilis. If this really is a myzostome, which is not unlikely as similar endoparasitic species occur in starfishes (Asterias, Stolasterias and Ceramaster) and astrophytons (Gorgonocephalus eucnemis and G. arcticus), we find in the crinoids the five following groups of myzostome species: 1. Wandering species which move about freely and actively over the body of the host, as Myzostomum cirriferum. 2. Sedentary species which rarely, if ever, leave the spot where they have settled, as M. parasiticum. 3. Cyst-producing species which cause the formation of galls or swellings on the arms or disc, as M. cysticolum. 4. Entoparasitic species inhabiting the digestive tract, as M. pulvinar. 5. Entoparasitic species living in the ovaries, as Protomyzostoma polynephris does in the astrophytons. Thus in the crinoids we find a single group of animals which, broadly speaking, play the part of the fleas, lice, jiggers and bots, intestinal worms and flukes combined as we know them among the land vertebrates. A comparison between the myzostomes and the species of Thrips, occurring only on flowers, is also interesting. In the vertebrates the blood with its multitudes of red corpuscles which when destroyed are promptly and continuously renewed is the logical food of practically all the parasites which do not inhabit the intestinal canal. The dilute blood of the crinoids, without structures corresponding to the red corpuscles, has none of the features which make the blood of the vertebrates such a reservoir of concentrated food. But the uncountable myriads of minute organisms flowing continuously downward along the ambulacral grooves and into the mouth form a stream of nutrient fluid in many ways analogous to the 38 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 vertebrate blood stream, and it is from this source that the myzostomes as well as most of the other parasites derive their subsistence. The species in each group parasitic on the crinoids in those cases in which our information is sufficient to permit us to speak with a reasonable amount of certainty follow bathymetrically and geo- graphically the distribution of the classes to which they belong quite regardless of that of their hosts, and apparently, excepting possibly in the case of Stelechopus, the most primitive of the myzostomes parasitic on the most ancient of the living crinoids, there is not the slightest correlation between the systematic position of the parasite and that of the crinoid. An undetermined internal worm, a parasitic ostracod, Laphysti- opsis, Anilocra, Cirolana (fig. 60), Cyclotelson (fig. 61), Synalpheus, Periclimenes, Pontoniopsis, Galathea (fig. 59), Ophiactis, Ophiomaza, Ophioethiops, Ophiophthirius, Ophiosphera, Sabinella and Polynoé are known as parasites on crinoids only in the Indo-Pacific region, though Laphystiopsis, a parasitic ostracod (on fish), Sabinella, Synal- pheus, Periclimenes, Galathea, Anilocra, Cirolana, Ophiactis and Polynoé also occur in the Atlantic. Collocheres, Enterognathus, Stylina and Hemispeiropsis are known as parasites on crinoids only from the Atlantic; but all of these are small and must be especially searched for; probably all occur in the Indo-Pacific. Mortensen’s parasitic worm of doubtful affinities is only known from the Antarctic; but only Notocrinus virilis offers a suitable habitat for it. Thus while the myzostomes occur wherever crinoids are found the majority of the other parasites and commensals on crinoids are con- fined to the Indo-Pacific region, though many are very closely related to nonparasitic Atlantic species. The chief reasons for this are probably the absence of a richly developed littoral crinoid fauna in the tropical Atlantic comparable to that in the Indo-Pacific region, and the plating of the ambulacra in most of the tropical Atlantic types, including the littoral species, which renders them unavailable as a source of food to most of the parasitic forms. It is interesting to note that, with the exception of the myzostomes and the gasteropods, the great majority of the organisms which are directly or indirectly parasitic upon the crinoids are confined to the littoral zone. The reason for this is probably to be found in the development of side and covering plates along the ambulacral grooves of the pinnules, arms and disc of the crinoids from intermediate and great depths which enables the animals to convert the ambulacral NO. 7 SEA-LILIES AND FEATHER-STARS—CLARK 39 grooves into closed tubes and prevents the appropriation of food particles by the ectoparasitic crustaceans, the ophiurans, and the polynoid worms. The larger commensals living on the crinoids are usually striped or banded, and resemble them more or less closely in color, though in many cases the closely related noncommensal species are quite plain. This may or may not be the case with the myzostomes. In regard to the parasites and commensals of the comatulids there is one curious feature which stands out very prominently—the majority of the records, especially of the larger and more vigorous types, are based upon species of the family Comasteridz, probably the most specialized of all the comatulid types. COMMENSALISM OF THE CRINOIDS A number of small comatulids and the young of certain others may be considered as truly commensal, living as they do in the cavities of large sponges and gathering the minute organisms brought to them by the currents flowing into the afferent openings of the host. Many others habitually cling to gorgonians or withdraw into crevices in corals where they live symbiotically, but quite independently of the supporting organism. ? ECONOMIC VALUE OF THE LIVING CRINOIDS Economically the crinoids serve no useful purpose—at least up to now they have been put to none. They cannot be eaten, and they are not, so far as we know, eaten by any fish or other animal that serves as human food. As a result of their ordinarily fixed mode of life it is possible that they might be used to furnish an index of the density of the finer plankton content of the water in which they live, though it is probable that other more generally distributed animals with more or less similar feeding habits would serve the purpose better. Because of their beauty and delicacy of form as well as on account of their rarity they are frequently preserved and offered for sale as curios in Japan and China and, less frequently, in India, Oceania, Australia and the West Indies. In southern Japan crinoids are frequently brought up on the long lines used for fishing in deep water in Sagami Bay. The comatulids, because of their beauty and delicacy of form, are called “ komachi ”— a name originally borne by an exceptionally well-favored lady of the court upwards of a thousand years ago—while the local stalked crinoid (Metacrinus rotundus) is known as the “ bird’s foot.” The 40 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 former when well preserved are sometimes sold as curios, while the latter,always meet with a ready sale at extraordinarily high prices on account of their rarity combined with their paleontological interest. In China comatulids are sometimes offered for sale which have been brought from a considerable distance. At Barbados the local species of [socrinus, especially I. asteria, and Holopus rangu, are occasionally to be found in the curio shops. Among the Slavic peoples red is the color about which all their abstract ideas of beauty, and hence of idealism, revolve. The delicate and often gorgeously colored red Adriatic Feather-Star (Antedon adriatica) occurs more or less abundantly along the coasts of the largely Slavic provinces of Istria and Dalmatia where it is frequently found in the fishermen’s nets and is sometimes brought up on their hooks. Its beauty of form, and particularly its red color, especially commend it to the local fishermen, who commonly take it to market and exhibit it along with the fish offered for sale.

Mitrer, Jr.] In translating Doctor Winge’s “Udsigt over MHvalernes indbyrdes Slegtskab” (Vidensk. Medd. fra Dansk naturh. Foren., vol. 70, pp. 59-142, 1918) my aim has been to give the author’s ideas as clearly and exactly as possible rather than to make smooth English sentences. I have been much aided by the kindness of Dr. Leonhard Stejneger, who has compared the entire MS with the original, making himself responsible in particular for the rendering of the adverbs ret, sikkert, vel, and vist, whose idiomatic shades of meaning present many difficulties to one whose acquaintance with Danish is limited to the printed language.

Brackets are used to distinguish all additions to the original text——G. S. M., Jr. The Cetacea * originated * from the Hyenodontide, the most primi- tive family of the Carnivora, by way of the most typically carnivorous members of the group such as Pterodon and Hyenodon. The oldest known whales have such a great likeness to Hyenodon and its nearest relatives that there can be no doubt about the relationship. Aquatic habits have given the cetaceans their special peculiarities and have caused their differentiation from the Hyznodonts. As an inheritance from the highest Hyzenodonts, and as an indica- tion ‘of relationship with exactly these animals, the most primitive whales retained a series of special peculiarities which the Hyzenodonts had developed in the course of their differentiation from the insectiv- orous stage. They still had about the same dentition as the Hyzeno- donts. All the teeth were fitted for flesh eating; the incisors and canines were strong and hooked, the anterior cheekteeth strong, elongated, compressed, smooth-edged; the molariform cheekteeth, especially those of the upper jaw, had a peculiar form and all of them were nearly alike. In the upper molars the 4th and 5th cusps [paracone and metacone] were coalesced to form a trenchant longi- tudinal ridge, the 1st and 2d cusps [parastyle and mesostyle] were reduced, the 3d cusp [metastyle] was a compressed ridge, and the *Notes are at end of paper, pages 47-93. SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 72, No. 8 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 6th cusp [protocone] was reduced or absent. All of the upper molari- form teeth including the third premolar still had the inner root, though this was in process of reduction. All the teeth of the typical [eutherian] dentition were present, 11 in each jaw [44 in all]. The jaws were elongated in harmony with the long, well-developed tooth- rows. The temporal fossa was very large, widened out by a powerful temporal muscle. It was bounded by a high sagittal crest, by a strong, backward-projecting occipital crest, and by an abruptly out- standing, posteriorly heavy processus zygomaticus squame. In addition to these peculiarities the most primitive whales had two high characters which were perhaps inherited from the Hyzenodonts ; at any rate they are to be found in the latter group, though less pro- nounced: a rather large supraorbital process, and a bony palat lengthened backward far under the posterior nares. Radical alterations have taken place during the change from Hyeenodont-like carnivores to true whales. In many of the mam- malian groups there have arisen forms modified for life in the water ; but no other aquatic mammals are modified to the same degree as the cetaceans, nor has any other become so exclusively aquatic; only to breathe do they raise the nose above the water in which they other- wise are hidden. The cetacea have used the tail as the chief implement of locomo- tion ; the hind limbs are put wholly out of service; the fore limbs are scarcely used for much else than steering and balancing. The tail becomes enormous, long and thick, powerfully muscled. It is formed in agreement with the manner in which it is wielded: with strokes from side to side, or up and down, or with a sculling motion. Throughout most of its extent it becomes compressed, but at the tip 1t acquires a powerful, horizontal, caudal fin constructed of skin folds (not present in quite young embryos of recent cetaceans). At the front of its upper margin, in the region where the tail joins the back, there may occur a special erect skin fold in the form of a longitudinal crest, a dorsal fin. Most of the caudal vertebrz lose the atrophied appearance which they have in primitive mammals; they acquire powerful centra, heavy, flat-outspread transverse processes, high dorsal arches with large, compressed spinous process, and articular processes which are distinct though not mutually fitting together. The ventral arches with the inferior spinous processes become so large that they approach the upper arches in size. Only the outermost caudal vertebre, which lie almost inclosed in the caudal fin, retain the degenerate character. The tail has an influence on the no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 3 dorsal vertebre also. Its powerful muscles, which have their origin in part on the sacral and dorsal vertebrz, and are also in connection with the muscles of the back, widen their place along the spinal column and stimulate the vertebrz to increase in bulk. The sacral and lumbar vertebre come to resemble the largest, most anterior caudal vertebrz exactly, apart from the lower arches. On a few of the hindmost thoracic vertebre, which in the ancestral forms are without, or as good as without, transverse processes, there grow out powerful transverse processes on a line with and similar to those of the lumbar vertebrz (parapophyses, apparently corresponding to the lower section of the double, rib-bearing “ transverse process ”’ of the anterior thoracic vertebree, which supports the rib’s capitulum ; but in reality they most probably correspond to the upper and lower sections combined), and on their tip they eventually bear the attach- ment surface for the rib. Apparently this surface may be either for the attachment of the tuberculum or of the capitulum or of the two coalesced, but in reality it is perhaps always for the two combined (or, more correctly, not separated). The transverse processes of the anterior thoracic vertebre (diapophyses, the upper portion of the double ‘“‘ transverse processes”), which in the beginning are quite short, may eventually grow long, pushing far out to the side the articular surface for the rib’s tuberculum which they bear at their extremity. On all the thoracic vertebre the spinous processes finally become high and strong. The hind limb atrophies completely, and disappears. At length only quite insignificant parts of its skeleton are found, hidden deep under the skin, finally in the form of a mere little rod-shaped bone, a ‘remnant of the pelvis.” In small embryos the hind limb can, however, still be distinguished externally. The disappearance of the hind limb has a great influence on the vertebral column. No longer does a pelvic bone come in contact with any of the vertebree. In consequence the sacral vertebree completely lose their peculiarities : their characteristic strength, their mutual firm connection, their robust transverse processes with flattened areas for the hip bones. They are formed exactly like the adjacent dorsal and caudal vertebre. The movements of the spinal column become changed in character. Bending of the column in the vertical plane, which depends especially on the movements of the hind legs, is reduced or abandoned, and as a result the differences in slant— forward or backward—of the spinous processes as good as disappear, val SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 so that all the processes alike are directed upward. The zygapophyses become reduced and in large part lose their mutual articulations. The fore limb, which no longer comes in contact with the earth or bears any load, is changed into a flipper whose single function is that of striking against the water. The entire arm becomes an oar blade. Of the fore limb’s articulations the shoulder joint only is used; it retains its ball-and-socket structure. All the other articulations are held stiff. They degenerate, become flat and immovable, or are wholly effaced. Practically the only function of the upper arm is to support the forearm and hand. It becomes short and heavy. Its middle portion retains its terete form, but its lower end is com- pressed in agreement with the bones of the forearm. The radius and ulna become very simply-formed, compressed bones, losing muscle crests, sinew furrows and all pronounced articular sur- faces ;,even the olecranon may wholly disappear. The mutual posi- tion of the two bones is somewhat altered, so that they eventually lie exactly fore and aft of each other. The hand is set somewhat supine, fore edge downward. The carpal bones become compressed, or more correctly flattened, pieces [like sections of a mosaic]. They are rather indifferent as to form and number, and are immovable. The folds of skin between the fingers are lengthened out to the finger tips; and the hand stiffens. The claws disappear. The first and fifth fingers are somewhat inclined to be stunted, but the other fingers, particularly the second, tend to lengthen and to form new joints at their tips, so that the number of phalanges may increase far beyond the typical three. The metacarpals and phalanges are shaped almost alike, as more or less flattened pieces of bone.” The shoulder blade degenerates only slightly. In the most primitive whales it already has the form which, with few exceptions, is found among the highest. It is broadly fan-shaped, with a prominent, antrorse acromion, and a large coracoid, but on the other hand almost without crista scapule. Rarely it becomes narrower or lacks both acromion and coracoid. The fact that the fore limb does not act as a support for the body results in lessening the limb’s pressure on the chest. Another result is that the spinous processes on the anterior thoracic vertebre lose their special height. Still another result is that the connections between the ribs and both the thoracic vertebree and the sternum have a tendency to become loose or to disappear. Perhaps this tendency is also brought out by the fact that the water pressure on the chest during diving changes strongly. The ribs may lose the capitulum, and the costal cartilage may practically disappear. When this happens No. 8 INTERRELATIONSHIPS OF THE CETACEA—-WINGE 5 the sternum loses an essential stimulus and becomes reduced and atrophied. The head, during swimming, is held directed as firmly as possible forward. The neck is not moved, and for this reason it becomes short and stiff. During motion through the water the head is pressed from the front; it is forced backward against the cervical vertebrze, which thereby are squeezed excessively together and pressed back against the anterior dorsal vertebree, with the ribs of which they may even come in connection. Most of the cervical vertebrae may become almost as thin as paper. The odontoid process of the axis becomes short and blunt; the articular surface between the bodies of the atlas and axis becomes almost flat. And there arises a strong tendency to coalescence of the cervicals.’ The occipital condyles lose their pro- jecting form and become almost flat, only quite weakly convex, pressed in against the wall of the braincase; and the concave surface of the atlas likewise becomes flattened out. The occipital crest in its capacity as an attachment for the upper neck muscles is restricted ; the points of attachment for the lower neck muscles on the basal part of the occipital bone are effaced, and the under side of the cccipital bone is formed more as a sheath around the gullet and windpipe. The pressure of the water on the head when the cetacean swims has a highly modifying effect on the skull. From above the water presses especially during the animal’s con- stant rising to the surface to breathe. This gives the skull.a tendency to acquire a flat and broad upper surface, with thick bones. The size of the horizontally outspread supraorbital process of the frontal, which pushes itself far out over the orbit, becomes particularly notice- able. The facial part of the cheek bone may likewise become pecu- liarly flattened out. From in front the water presses during forward motion, the more strongly as the motion is faster. Its effect is to develop an unusual strength in those bones of the face which project furthest forward, the intermaxillary, maxillary, and vomer, as well as in the cartilaginous nasal partition which the vomer embraces. This strengthening may show itself in different ways: in the noticeable lengthening forward of the bones in question, in their solid ossification, in their tendency to coalesce. It also appears in the backward spreading of the inter- maxillary and especially of the maxillary. The latter may extend itself out over the facial part of the zygoma and over the frontal, which it almost entirely covers to the hinder margin, so that the supra- orbital foramen may pierce not only the frontal as in other mammals. 6 SMITHSONIAN “MISCELLANEOUS COLLECTIONS VOL. 72 but the maxillary as well. The cartilaginous nasal partition, the mesethmoid, has a tendency to ossify. The incisive foramen is narrowed and closed. In the palate the maxillary pushes itself far backward, forcing the palatine behind it; the palatal surface of the palatine is thus shortened. But at the same time the maxillary acts on the palatine in such a way that it also increases in thickness. The braincase is acted on from the front by the pressure of the water against the forehead; from behind it is pressed by the cervical vertebree and the neck muscles. In this manner it becomes so squeezed that it acquires a short, broad form. Pressure is exercised especially on the frontal and on the supraoccipital and interparietal. These bones widen out at the expense of the parietal, whose inner- most part is squeezed quite narrow and eventually obliterated. The exoccipital also grows, especially noticeably downward, where it broadens out shield-like behind the mastoid and the tympanic. The mastoid is compressed inward between the exoccipital and the squamosal, by both of which it is so overgrown that at last it is no longer visible on the outer surface of the braincase. The water pressure on the head from in front has also a great influence on the soft parts of the face and through them on the skull. It assists in shifting the nasal apertures. The cetacean has tried, with the help of the nose muscles, to draw the apertures as high as possible up on the head’s upper side, in order to be able easily to get them raised above the water. The result has been that the nasal cartilage has caused resorption of the anterior border of the nasal bones and has forced them further and further back. The cartilage has also worked itself back between the anterior median part of the frontals, pushing the plates of the ethmoid behind it. Thus at last the nares have acquired a position which appears to be on the forehead but which in reality is close in front of the anterior wall of the braincase. The moving of the nasal cartilage has been accelerated in those cases where the facial adipose cushion which originally lay in front of the nares and which in the first place was merely a little filling out of fatty connective tissue has been stimulated to growth by the pressure of the water, becoming very large, pushing the nasal cartilage back- ward, pressing it against the front wall of the braincase and disinte- grating the nasal bones and the plates of the ethmoid. The nasals then become tuberformed and are pressed into the frontals. The adipose cushion together with the nasal muscles and other neighboring structures may exercise an enormous influence on the skull, the anterior and upper sides of which it modifies to form its bed, the “ facial depression.” no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 7 The water acts in a very special way where the whale lets it stream into the mouth for the purpose of catching the small animals which it carries in with it. In such cases it brings about huge increase in the size of the jaws together with many other remarkable peculiarities. For smelling there comes to be no use; this sense is not exercised, and the nose is therefore formed in accordance with the needs of breathing only. The ethmoid degenerates. The numerous folded laminze of which it originally consisted disappear, while the cribriform plate loses its nerve perforations and becomes a solid lamina of bone on the front wall of the braincase. The nose becomes a simple passage for air. The air, which is exposed to strongly varying pressure and temperature, has a tendency to provide itself with greater space by widening out the nasal passage and Eustachian tube wherever it meets with least resistance. It may form air-sacs, partly on the upper side of the skull over the facial bones, partly on the under side behind the palate. Here an air-sac may spread itself forward along the outer side of the pterygoid and palatine and back- ward along the outer margins of the body of the sphenoid and the basal part of the occipital, pushing itself out under the ala parva, ala magna and the squamosal, and bounded more or less by plate-like outgrowths from all the bones mentioned. The bony palate is lengthened backward still more by the pushing out from the ptery- goids of laminze which extend into the soft palate beneath the nasal passages. This clearly takes place partly under the action of the tongue, but doubtless still more under the influence of the larynx. The fact that the two original outer nostrils finally coalesce into one is an indication of the nose’s degeneration. The lacrimal bone is reduced and eliminated, or it fuses with the cheek bone as in many other aquatic mammals, probably because the bone is no longer acted upon by a lacrimal duct. The outer ear disappears from lack of use; the outer auditory aperture is so strongly contracted that it may be difficult to find. The bones of the inner ear acquire a peculiarity which is found again in several other mammals that live in the sea, and which cer- tainly in some manner or other must be dependent on aquatic life. They are formed of unusually thick, stony-hard masses of bone; this is especially remarkable as regards the tympanic, the inner wall of which is thickened in a peculiar way.” The dentition degenerates because the chewing of food is given up as not easy to carry on satisfactorily under water. Most animals chew with open mouth; under water the chewed food would be 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 washed away from between the teeth. The dentition is therefore chiefly used for grasping the food and holding it fast. In the most primitive whales the mouth did service as an implement for catching fish. The jaws were used in exactly the same manner as in the shell- drakes, Mergus, and they were produced forward as a long slim beak, a kind of tweezers, influenced not only by the use to which they were put, but also by the pressure of the water during swimming forward. The Hyenodon-like dentition which the most primitive whales inherited, with teeth of considerable size, diversified form, and of typical number, at first becomes more simple. The upper molariform teeth lose the inner cusp and the inner root, and the crown under- goes compression. A further step in the reduction is that the crowns of the cheekteeth, or at least of most of them, acquire a serrated anterior and posterior margin. Next the two remaining roots, foremost and hindmost, of the cheekteeth fuse into one, and the serrations of the crowns are reduced and obliterated. The size at the same time is reduced, and the form becomes simply conical so as to resemble that of the incisors and canine, which in their turn undergo reduction. While this is happening the number of teeth in the long jaws is increased, no doubt because in the place of the few quite large teeth there spring up many smaller ones; scarcely by the actual splitting up of the few. Perhaps also in the beginning some of the milk teeth came to take a place in the series with the permanent ones, without, however, the entire milk dentition’s intercalation in the permanent set. The number of teeth grows greater and greater, far beyond the typical, while the individual teeth become smaller and smaller. Those at the front and back of the series become especially stunted, frequently disappearing from the intermaxillary. The enamel covering of the teeth becomes thin or disappears entirely. What later happens to the dentition depends on the use to which it is put. It may happen that there comes to be no use whatever for it, and that it consequently disappears. Or it may, wholly or in part, be once more put to heavy use and be modified to this end; or a single tooth may take on power while all the others atrophy. The succession of teeth, which in the most primitive whales took place in the ordinary way, ceases. It is not clear how this happens. Judging from investigations of the teeth in embryos of the higher cetaceans it might appear, at least sometimes, as if it were retained milk teeth that are found in the adult animal’s dentition—as if the successors to the milk teeth had cisappeared. Such, however, is scarcely the explanation. Most probably it is really the actual perma- no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 9 nent set that is found in the adult, while those that precede and follow (both of which have been demonstrated) disappear.’ The fact that mastication ceases and that the teeth become stunted has a great influence on the chewing muscles and the jaws. It was necessary for the first whales as fish catchers to be able to open the mouth wide. The masseter muscle which has the tendency to limit the opening of the mouth was therefore little used, and it became restricted ; together with the muscle the region of its origin became shrunken. This region is the anterior and median part of the zygoma ; it is transformed into a slender bridge of bone. The tem- poral muscle has been more used, but it also shows the tendency to be reduced by lack of vigorous use, and it draws itself backward quite low on the side of the braincase, losing its influence on the zygomatic process of the squamosal. This process shrivels up like the coronoid process of the mandible, the muscle’s point of insertion. In cases where the under jaw becomes very large the temporal muscle may acquire renewed strength and may spread its region of origin out over its surroundings in an unaccustomed manner. With the atrophy of the teeth they cease to influence the body of the mandible, which consequently loses its original height. The alveoli become less defined and the partition walls between them may disappear so that there arises a common dental furrow. The articular condyle of the mandible weakens, loses its cylindrical form, and the articular sur- face becomes an almost flat area pointing backward at the similarly formed glenoid fossa on the squamosal, which as good as loses its postglenoid process and is otherwise inclined to suffer reduction. It may happen, however, that the lower jaw becomes huge and that its articular condyle acquires corresponding heaviness. In such cases the condyle is curiously modified, losing the true articular surface. This is grown over by articular ligament, and the lower jaw stimu- lates the squamosal to grow out in prodigious size, bearing, instead of the true articular surface, an area of attachment on a projecting foot. The symphysis menti. long in the most primitive whales, is restricted. The under jaw’s degeneration is also no doubt indicated by the huge gaping posterior entrance to the mandibular canal, which is mostly filled with loose connective tissue. It is not clear what the reason is for this peculiarity, which was already present in the most primitive cetacea and is found in all the later ones though sometimes in a rather disguised form; possibly it might in some way depend on the air-sacs of the nasal passages which lie exactly internal to this part of the lower jaw. 10) SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Whales lose their hair covering because it ceases to be of use; at most some few degenerated vibrisse remain. It holds good for the cetacea as for other groups of mammals that the most primitive forms have much less brain than the later ones; in the highest whales the brain is extremely well developed. It likewise holds good for the cetacea as for others that the earlier forms are smaller than the later, though dwarfs may at any time be developed. Ordinarily whales increase noticeably in size as they become more highly developed; the highest forms have reached gigantic proportions. Judging by their greater or less resemblance to the Hyznodonts the cetacea are mutually related essentially as follows: ” Cetacea. I. The number of teeth is not more than typical [44].

Zeuglodontide [| Basilosauride|—Of all known cetacea the Eocene Egyptian Protocetus of the family Zeuglodontide is the most primitive. It is known from a rather complete skull without the I2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 lower jaw, and from a few vertebre and ribs. In all that is known it stands so near to the Hy@nodontide that there would scarcely have been any reason to separate it from them had it not been evident that it was one of the first members of the cetacean series. The number of teeth in the upper jaw is, as in Stypolophus and Pterodon, the typical 11, since m* is present, while it has disappeared in Hyenodon, the highest genus of Hyenodontide. But the form of the teeth is most nearly as in Hyenodon, more shearing than in other members of the family. The difference from Hyenodon is chiefly a result of the fact that heavier use has been made of that part of the toothrow which serves for grasping the food and that consequently the incisors and anterior cheekteeth have increased in size. The incisors have become about as heavy as the canine, the premolars have become heavier and more elongated than formerly, while the molars are weakened and m? has lost its predominance. The mouth was already used mostly as a pair of forceps; the long, narrow, but strong, beak- shaped jaw, in which the teeth have abundant space, bears witness to the fact. The anterior nasal aperture is already forced consider- ably backward; but it has, however, only reached a point scarcely half way to the anterior margin of the orbit, and it has kept a rather primitive form. The nasal bone is long and narrow, roofing over a large part of the nasal cavity. The intermaxillary is strengthened anteriorly, its body is lengthened, likewise its nasal process, though this process does not reach to the frontal. Otherwise the inter- maxillary does not show much deviation from the conditions ordi- narily found in carnivores. The maxillary also is lengthened and thickened, but is not otherwise modified to any noticeable degree. Posteriorly it does not push itself out over the facial part of the zygoma or over the frontal, which it merely forces slightly backward. On the palatal surface it has not crowded the palatine bone, which has retained its original length. The incisive foramina seem to have disappeared. The forehead is pressed quite flat, and the supraorbital process of the frontal has become very broad; otherwise the forehead is unmodified. The anterior and median part of the zygoma is already well on its way to become slender, but the zygomatic process of the squamosal is still robust. It bears a considerable postglenoid process, though the articular surface for the lower jaw has begun to assume the: peculiar vertical position that it has in the higher whales. The temporal fossa has on the whole remained primitive in size and form. It is bounded by high crests. The braincase is not compressed antero-posteriorly ; the frontal and supraoccipital are No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 13 not widened so as to encroach on the parietal. The mastoid is still visible on the outer wall of the braincase. Occipital crest well developed, projecting. Occipital condyles not pressed flat. On the basal part of the occipital the impressions where the lower neck muscles were attached are essentially unmodified in character, and the under side of the occipital bone’s basal part is not shaped for sheath- ing the gullet and larynx. On the other hand the exoccipital has already acquired a noticeable widening out to the side. The hinder part of the nasal cavity appears to be wholly undisturbed ; it must contain a well-developed ethmoid. The bony palate is already pro- longed backward by plate-like outgrowths from the lower margin of both the palatine and the pterygoid. No doubt an air-sac formed by an enlargement of the nasal passage lay on the outer side of the pterygoid, but whether it was enclosed by outgrowths from the adjacent bones is doubtful. The tympanic bone had already acquired the characteristic cetacean thickening of the inner wall. The cervical vertebre are mutually free, not strongly compressed. The odontoid process of the axis is strong, projecting. The spinous processes of the dorsal vertebre differ noticeably among themselves as to their slant, some of them sloping strongly backward, others upright or directed a little forward; those on the hindmost dorsal vertebre are rather low. Zygapophyses apparently well developed. No project- ing transverse processes on the hindmost thoracic vertebrae. Centra of ordinary size. On the tip of the transverse process of a sacral vertebra there is present a rather large area of attachment for the ilium, although the process has otherwise already lost much of its original character. On such ribs as are present in the fossil there is a well-developed capitulum; the hindmost ribs lack the tuberculum and are articulated with the corresponding vertebrz by the capitulum. Progeuglodon (Zeuglodon osiris, Prozeuglodon atrox partim”), also Eocene, Egyptian, has departed in dental characters not a little from Protocetus. In the number of teeth the difference is only that m*, small in Protocetus, is here absent. The form of the teeth has undergone greater change: pm’ has lost the compressed form of the crown and has become simply conical with a single root like the incisors and canine; pm? has acquired a serrate posterior margin; pm’, pm*, m+ and m? are strongly serrated on both the anterior and posterior margins of the crown; in pm? and pm‘ the inner heel is much reduced and in the two molars it has entirely disappeared. The lower jaw is also known; it contains the typical 11 teeth. Incisors, canine, and pm, approximately uniform, simply conical; pm,, pm, 14 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 and pm, with compressed crown and serrated anterior and posterior margins; m,, m, and m, also with compressed crown, its anterior margin smooth, its posterior margin serrate. Tooth succession occurred in the ordinary way as it assuredly did in Protocetus also. In all characters the skull agrees essentially with that of Protocetus. The basal part of the occipital appears, however, to be more adapted to the larynx and gullet. A few peculiarities of Prozeuglodon which are not clearly demonstrated in Protocetus are: the presence of an elongated, compressed incisive foramen on each side; the presence of a distinct lacrimal bone; and the presence to the outside of the pterygoid and in front of the tympanic of a considerable pit bounded by high ridges springing from the surrounding bones, evidently the impression of an air-sac. The under jaw already has nearly the same peculiar form as in many highly developed cetaceans with long symphysis menti; it has, however, a relatively large coronoid process. But the mandibular condyle is placed low and is turned backward, and the strange gaping hinder entrance to the mandibular canal is present. Of the rest of the skeleton rather more is known than of Protocetus, among other parts most of the vertebral column and the fore limb down to the hand. There is a great similarity to Protocetus. A difference from this genus is that no sacral vertebra is found with the transverse process plainly acted upon by the ilium. The skeleton of Prozeuglodon throws light on certain conditions that are not under- stood in Protocetus. The sternum is of considerable size, with several joints. The shoulder blade is essentially as in the higher whales. The humerus has retained relatively much of the original form: distinctly separated greater and lesser tubercles, a distinct deltoid crest, and a well-developed hinge-shaped lower articular surface. Radius and ulna have correspondingly well-developed articular sur- faces for the humerus, are relatively only a little compressed, and have distinct articular surfaces for the carpal bones; the ulna has a rather large olecranon. Zeuglodon [Basilosaurus| (Z. cetoides, Z. isis), known rather completely as to the skeleton, occurs in Eocene strata of both the Old and New Worlds. In most respects it resembles Prozeuglodon. But it has acquired a highly remarkable peculiarity in the vertebral column. While the centra in Progeuglodon are not in any direction strikingly altered in form, in Zeuglodon the centra of most of the hinder thoracic vertebre, of the lumbar vertebrz, sacral vertebrz and all but the outermost of the caudal vertebrae, have become remarkably large and especially greatly elongated, while the vertebral arches have remained short, standing about midway on the centra, the arches, no. 8 INTERRELATIONSHIPS OF THE CETACEA——-WINGE I5 in common with the spinous processes, widely separated from each other. Thus in Zeuglodon the body has acquired an altogether peculiar length, putting one in mind of the snakes. The posterior thoracic vertebree seem to have developed considerable transverse processes which bore the ribs on their extremities. In size also Zeuglodon went further than its relatives. Of the hind limb there is known a small, quite atrophied pelvic bone with articular surface for the femur, and an even more degenerated little rod-shaped femur.” The genera of Zeuglodonts together form the section Archzoceti, the source from which all the higher cetaceans have originated. Pro- tocetus has scarcely a single peculiarity, apart from its large size, that one would not expect to find in an ancestral stock for the higher whales. The same is true of Prozeuglodon. On the other hand Zeuglodon, a descendant of Prozgeuglodon, has followed its own line away from the starting point of the other whales, deviating particu- larly in its remarkable vertebre. The peculiarities which especially place the Zeuglodonts lower than all other cetaceans are that the teeth are still present in the typical number, and that the braincase is not telescoped and shortened. Of all other whales it holds good that they, so far as they are known. have the number of teeth raised above the typical (or that they are descended from cetacea in which it had been raised), and that they have the braincase more or less compressed antero-posteriorly. As regards the form of the teeth Protocetus no doubt stands lower than all other cetaceans; but Prozeuglodon and Zeuglodon are in this respect scarcely more primitive than the lowest members of the higher families. Of all the many other primitive characters that are found in the Zeuglodonts some are, it is true, no longer to be found in the higher families, not even among the extinct lowest forms; but for most of them this does not hold good.

They presumably had the number of cheekteeth raised above the typical. With that change there followed others. The most primitive Mystacoceti must have already had the nasal aperture pushed further back than in the Zeuglodonts. The intermaxillary probably extended further back. The maxillary must have been somewhat more broadened out posteriorly. The parietal was slightly encroached upon, and the braincase was a little tele- scoped. The spinous processes of the dorsal vertebrze presumably slanted to a less degree in different directions. The joints at the elbow and wrist must have almost wholly lost their primitive structure, etc. Taken all in all, however, the most primitive Mystacoceti must have been in general like the most primitive Zeuglodonts. Of the many forms which the group Mystacoceti must have in- cluded no others are known than a little circle of highly developed genera very specially modified in their own direction; but in spite of their remarkable development they have retained many primitive features which are no longer found in the other, higher families. This holds good especially in the structure of the face. Although the narial aperture is drawn backward into proximity with the anterior wall of the braincase the nasal bone is not wholly misshapen. It retains part of its long, narrow form and it still roofs over the hind part of the nasal cavity which may yet inclose very considerable remnants of the ethmoid plates. The anterior part of the nasal cavity, bounded by the intermaxillary, maxillary and vomer, is also relatively primitive in structure, more open than usual, with less tendency to closing together of the bones. And the maxillary, although it has expanded backward, and shoved itself somewhat back both above and beneath the frontal, has nevertheless not in any way covered the frontal’s broad supraorbital process. A distinct lacrimal is present, but this is not unknown among higher cetacea. The zygomatic arch has retained more of its primitive form and strength than elsewhere. Two outer nasal apertures are still found; they are not mutually united. The basal part of the occipital is also to a somewhat less degree modified than in other recent cetacea, being less specialized to accommodate larynx and gullet. That which more than anything else has left its impress on the known Baleenids is their habit of not hunting after single large fish, but of swimming with open mouth into shoals of small fish, crus- no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE V7 taceans, or other small creatures, which they allow to stream into the mouth in multitudes along with the water. They seek to retain the edible contents when they close the mouth and the water flows out again between the lips. The water has thereby acquired great power to act upon the mouth cavity from within; it distends the opening enormously ; the jaws grow and acquire a disproportionately large size in comparison with the braincase; the branches of the mandible are bowed strongly outward to the sides and are widely divergent from each other behind, while the connection between them in front becomes quite loose. The gigantic lower jaw wears so upon the ligaments which bind its articular head to the squamosal that the ligaments are incited to growth. They become uncommonly strong and spread themselves over the original gristle-covered articular surfaces on the jaw and the squamosal, both of which surfaces they entirely cover. They cause the squamosal to grow out as a huge process which bears the attachment surface for the lower jaw on its free margin. By the enlargement of the mouth cavity the squamosal together with the articular head of the lower jaw is pushed far out to the side and so far back that at last its free postero-external extremity comes to lie further back than the occipital condyles. The squamosal in its turn presses strongly on the parts which lie behind it: on the mastoid which is squeezed inward, and on the exoccipital which is pushed backward. In proportion to the size of the under jaw the temporal muscle increases and pushes its region of origin -forward over the supraorbital process. There has been no use what- ever for the teeth; they atrophy so completely that finally they are to be found only in the embryo as a long series of insignificant, small, pin-shaped teeth, hidden under the skin and soon resorbed. On the other hand the inflowing and outflowing water acted as a stimulant on the corneous papillz of the roof of the mouth. The papille along the margin of the upper jaw are so stimulated that they have grown out as a close-set series of ‘‘ whale-bones ”: high, crosswise-placed, corneous plates, the inner margin of which is frayed out into threads. _ The entire set of whale-bones functions as an excellent instrument for catching the solid material that flows with the water into the open mouth. The palate is strongly acted upon by the instreaming water, by the larynx, and by the tongue, which is pressed against it when the water is to be expelled. The palatine bone grows and forces itself backward, pushing back the pterygoid behind it; and the pterygoid pushes and presses that which lies still further back ; namely, the tympanic bulla and the region of attachment of the neck 18 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 muscles on the basal part of the occipital. The palatine may push itself wholly back under the base of the occipital, and the muscle attachment may come to lie about on a line with the posterior margin of the occipital condyle. In other respects also the known Baleenids have reached particu- larly high. The supraorbital process of the frontal acquires an unusual breadth, no doubt for the special reason that it follows the eye, which, by the widening of the mouth cavity, is pushed out to the side. The supraoccipital becomes very large and strongly slanting forward under the influence of pressure by the water and by the muscles of the neck. The transverse processes of the thoracic verte- bree become widely projecting ; this is especially noticeable as regards the hindmost thoracic vertebree (where the processes are para- pophyses, while on the anterior vertebrzee they are diapophyses). The ribs have a strong tendency to lose the capitulum and to restrict their connection with the sternum. In most of the recent members of the family the capitulum is absent from all the ribs, even the more anterior, although an evident collum is present (it is, however, doubt- ful whether it is really the capitulum that is absent from the hind- most ribs; more likely the single articular head which appears to be the tuberculum is in reality either the capitulum alone or the capitulum and tuberculum undifferentiated). The sternum is so reduced that it consists of the manubrium alone. The first finger has a tendency to atrophy. Etc. In the section Balzenini are found the most primitive of the family’s known genera: Balena and Neobalena. With them the anterior facial part of the skull has kept relatively much of the form ordi- narily present in mammals. This is especially true of the inter- maxillary and still more of the maxillary, which is quite slender in front and not depressed. Body and tail are rather short, not quite so well fitted for rapid swimming as in the others. The hand is more primitive. Of the hind limb’s skeleton there are present, at least in Balena, relatively quite considerable remnants, among other parts a _ stunted femur and the upper end of the tibia. The mouth is shaped somewhat differently than in the others ; it is formed as an enormous barrel or bag, bowed outward on all sides. Not only are the rami of the lower jaw bent outward, but the upper jaw with the whole facial part of the skull is also bent, arched highly upward. Both the upper jaw and the branches of the lower jaw assume the structure of stays in the walls of the pouch-like mouth cavity. The whale-bone plates acquire a remarkable length. Finally the head becomes more pre- no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE I9 ponderant as regards the body than in other whales. The cervical vertebrz are pressed together unusually strongly ; they coalesce. Balena appears in some respects to stand on a lower level than Neobalena. Its slender under jaw seems better to agree with the condition primitive to the cetacea than does the strikingly massive, strongly compressed under jaw of Neobalena in which the mandible presumably must be especially influenced by the large under lip. Its relatively few, ordinarily formed, slender ribs, and its correspond- ingly rather long series of lumbar vertebre are also undoubtedly primitive characters; in Neobalena the ribs have become unusually numerous and the number of lumbar vertebrz is reduced to a few bones, while the ribs, or at least most of them, have become remark- ably broad and have to a remarkable degree lost connection with the vertebre so that they lie loose among the muscles. Balena is no doubt the more primitive also in the short, broad form of the hand. The first finger is either (in B. australis) rather well developed, con- taining two phalanges in addition to the metacarpal, or (in B. mysti- cetus) reduced, though still retaining the metacarpal.“ The other fingers are not much lengthened; in the median digits, however, especially in the third, the number of phalanges may be increased to four or five. The form of the phalanges is terete, not compressed. In Neobalena, the hand appears to have essentially the same structure as in Balena, but the first metacarpal is said to be absent, and the entire hand has become narrower. The lack of a dorsal fin in Balena, in contrast with Neobalena, is, presumably, also a primtive character ; though the fin may have been lost. But in the adaptation of the head as a pouch for catching small animals Balena has reached far beyond _Neobalena. In the more primitive of the two certainly known species of Balena, B. australis, the modification is a little less noticeable than in the higher species, B. mysticetus; the head is slightly smaller, the upper jaw is somewhat less bowed upward, etc. In B. mysticetus the head becomes so huge that in full grown individuals it reaches a third or more of the animal’s total length, the upper jaw is thrown upward in an enormous arch, the palatine and pterygoid are forced backward under the hindmost part of the basioccipital, etc. The coracoid process of the scapula may be absent (in B. australis). Neobalena must assuredly have originated from Balena, but from one of the most primitive species of the genus, in which the head was only a little increased in size; but since then it has gone its own way, developing peculiarities in the form of the lower jaw, in the ribs, vertebral column and hand. 2 20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL In the genera of the section Balenopterini the intermaxillary and also the maxillary are rather strongly flattened anteriorly so that the facial part of the skull has lost its primitive pointed form. Body and tail are uncommonly long, adapted to more rapid swimming with stronger muscles. Among the alterations produced by these muscles are the higher spinous processes on the dorsal and caudal vertebre. The hand is shaped more like an oar blade. The fingers are laid more closely together and the third and fourth may have the number of phalanges increased ; the first digit has completely disappeared. The skeleton of the hind limb is more reduced. The mouth is modified in its own way; its outbowing in the upward direction is slight or absent, that to the sides and downward is conspicuous. The floor of the mouth cavity has become to a high degree expansible, and the intermaxillary and maxillary, like a broad, more or less flattened lid, cover over the pouch which it forms. The Balznopterines stand lower than the known Balznines in the condition of the cervical verte- bree: the bones retain their freedom. Among the known Balznopterines, Rhachionectes is one of the most primitive. Its nasal bone is still relatively very well developed. The breadth of the intermaxillary and maxillary in front is rather slight. The supraorbital process is relatively weak and not strongly flattened. The braincase is relatively only slightly telescoped so that on the middle of its upper side there can be seen not a little of the frontal. The supraoccipital is not especially large or forward-slanting. The articular surface for the lower jaw on the squamosal is not pushed out especially far downward and backward, and, when seen from beneath, has not entirely covered the mastoid or pushed the exoccipital very far backward. Bony palate relatively not strongly lengthened behind. The point of attachment for the neck muscles on the basal part of the occipital is still tubercular, and the basioccipital on the whole is only to a slight degree shaped to accommodate the larynx and gullet. . In contrast with its nearest recent allies Rhachionectes stands lower in a few other respects also: an evident capitulum is still found on some of its anterior ribs; the skin beneath its mouth cavity is not thrown into longitudinal folds; the dorsal fin is not present ; the hand is relatively short, and the number of phalanges is only a little increased. It has perhaps high specializations in its decidedly heavy under jaw, which slightly suggests Neobalena, and in its somewhat upwardly arched facial portion of the skull. Plesiocetus from the Tertiary of Europe, and presumably from that of North America also, is best known from the skull. To a high no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 21 degree it resembles Rhachionectes, but appears to differ in having a considerably more reduced nasal, like the higher Balzenopterines. Cetotherium, also from the Tertiary of Europe and presumably of America, which is likewise known from scarcely anything else than the skull, is a very near relative to Plesiocetus. It is slightly more specialized, with the articular surface for the lower jaw on the squamosal pushed somewhat further backward, pressing more against its surroundings, and covering the mastoid; but otherwise it scarcely differs except in trifles. As a pronounced contrast to Rhachionectes the genus Balenoptera, on the other hand, stands much higher: with much smaller nasal; with intermaxillary and maxillary more broadened in front; with broader and flatter supraorbital process; with more telescoped brain- case in the median upper part of which there shows itself only a little of the frontal; with larger, more forward-slanting supraoccipital ; with the articular surface for the lower jaw on the squamosal pushed much further backward, wholly covering the mastoid and shoving the exoccipital more to the rear ; with bony palate strongly lengthened backward ; with point of attachment for the neck muscles on basal part of occipital compressed, flattened; with the basioccipital more shaped to the larynx and gullet ; with the skin under the floor of the mouth cavity thrown into longitudinal folds; with a dorsal fin; with the hand more lengthened; with frequently more phalanges in the median fingers. Magaptera stands yet higher than Balenoptera. Its body is relatively not much elongated, a fact which points to its origin among the most primitive species of Balenoptera. But in the structure of the fore limb it has reached far beyond its relatives. On account of some special use or other, perhaps most likely from rapid turning about in the water, the arm has grown to an enormous length. The forearm has become very much stretched out, and the hand is yet more conspicuously lengthened, the number of phalanges in the third and fourth finger increased in addition. The scapula has lost both the coracoid process and the crest. Balenide.™ I. Intermaxillary and maxillary narrow anteriorly, not flattened. Balenini. A. Mandible slender. Ribs not broad.

Squalodontide.—The Squalodonts must have originated from among the most primitive Baleenids which still had the teeth shaped like those of the Zeuglodonts but increased in number, and which had not yet begun to get the mouth refashioned into a catching-bag. Their differences from the most primitive Balenids are due especially to stronger pressure of the water on the facial part of the skull; most likely the Squalodonts were from the beginning more rapid swimmers than the Balenids. The nasal passage is pushed much further back, not by muscle action alone, but probably especially by the influence of the facial adipose cushion. The water both stimulates the cushion to growth and presses it against the nasal passage. The nasal bone is completely atrophied, almost tubercular in form, and pressed into the frontal in the fore wall of the braincase, not or almost not cover- ing over any part of the nasal cavity. The plates of the ethmoid are probably pushed wholly away and the lamina cribrosa has probably become a solid bone-plate without perforations or almost so. The nose muscles, the pneumatic diverticulum from the nasal passage, the adipose cushion of the snout, in short all that covers the skeleton of no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 23 the face, is pressed by the water in against the bones and has moulded the upper side of the whole face as its bed, especially hollowed out posteriorly. This bed, the “facial depression,” extends backward along the sides of the nasals on the forehead. The beginning is traceable of a remarkable peculiarity which, in the more advanced cetaceans may become conspicuous to a high degree: an asymmetry in the structure of the face. The head must no doubt be so held during motion that the water comes to press not quite equally on both sides, but more strongly on the right side than on the left. The facial cushion therefore becomes larger on the right side than on the left, extends its bed most on the right side, forces the nasal passage to bend over to the left, and causes the bones of the face to develop somewhat dissimilarly on the two sides.” The maxillary has pushed itself posteriorly up over the frontal to such an extent that it almost wholly covers it, also spreading out over the supraorbital process. The zygoma appears to have been quite slender. The two nasal aper- tures were presumably united into one. In all of these points of difference from the Balzenids the Squalodonts agree with the higher cetacea, of whose most primitive forms they remind one in nearly everything, so far as they are known, except in the condition of the teeth. . The Tertiary North American Agorophius, which is only known from a very incomplete skull, almost without teeth, appears to be the most primitive member of the family. The number of teeth is not known, but certainly, to judge by the other peculiarities of the genus, it must have been greater than typical. Its braincase is much less telescoped than in the other Squalodonts, also less than in any of the known Balznids, somewhat suggesting the Zeuglodonts in being relatively strongly constricted anteriorly between the large temporal fossee, and in having the parietal form a considerable part of its roof. In the other Squalodonts the braincase, so far as it is known, is so telescoped and so broadened out to the sides that there is a wide area between the temporal fossz although these are relatively large; also the parietal in the middle of the roof of the braincase shows itself at most as a narrow band. In other respects Agorophius appears to agree well with Squalodon. Squalodon is known rather completely from skulls from Tertiary strata in both the Old and New Worlds. Almost nothing is known of other parts of the skeleton. The teeth are well developed, hetero- dont. In each jaw there are three incisors with conical crown and single root, a canine of similar form and size, and I1, or sometimes 24 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 in the upper jaw 12, cheekteeth. Of these last the four or five anterior have conical crown and single or bifid root, and the seven posterior have compressed crown with more or less serrate anterior and posterior margin (or only the posterior margin serrate), and two roots, an anterior and posterior. The fact that the number of cheekteeth is most often 11 might indicate that the increase above the typical number, seven, was produced by the intercalation of four milkteeth in the series with the seven permanent teeth; but there is no decisive evidence either for or against this explanation, as the tooth succession is not known. If the number exceeds 11 a true increase must have taken place. As in the most primitive of the higher whales the jaws are very elongate, narrow; the intermaxillary and maxillary are not especially closed together, and the mesethmoid is not ossified in front; the symphysis menti is long (the rami of the mandible may have grown together) ; the facial depression does not extend very far backward, the braincase is relatively only a little telescoped, the temporal fossa is considerable, the zygomatic process of the squamosal strong, the occipital condyle projecting. The Tertiary European Neosqualodon is only known from pieces of jaws. It has the number of serrate cheekteeth raised to at least 11; otherwise the characters of the dentition are not known. The Tertiary Argentinian Prosqualodon, known from the more essential parts of the skull, differs from Squalodon in having a much shortened face, with the facial depression relatively strongly broad- ened behind. The number of teeth appears to be somewhat reduced. It is no doubt a little more primitive than Squalodon in the less strongly telescoped form of the braincase proper. Squalodontidz.” I.

The most important and perhaps in the first place the only distinction between the Platanistids and their precursors among the Squalodonts is that the teeth in the Platanistids are to a higher degree structurally degen- erated. They have lost their heterodonty, have become smaller but more numerous, all of them nearly simply conical with a single root. On the other hand the Platanistids have retained most of the other peculiarities in which the Squalodonts show themselves to be relatively primitive. Especially noticeable in comparison with higher cetacea are the following characters: facial depression rather narrow, not much widened laterally behind, so that its outer margin covers over the temporal fossa to a slight degree only; temporal fossa rather large ; zygomatic process of the squamosal robust; all these peculiari- ties are no longer or scarcely ever found among cetacea of the higher families. The braincase appears to be rather small and not very much compressed antero-posteriorly, this also in contrast with the higher whales. In common with the most primitive forms of the higher cetacean families the Platanistids have, so far as they are known, such peculiarities: as the mutual independence and rather considerable size of the cervical vertebrz ; as the conspicuous lack of uniformity in the shape of the dorsal vertebre (for instance the long, broad transverse processes of the lumbar vertebrz in contrast with the rather short processes of most of the thoracic vertebrz ; only on a few of the hindmost thoracic vertebree do there occur robust transverse processes, parapophyses, which bear ribs at their tips in the Platanistids that are known in this respect ) ; as the well-developed heads to the anterior ribs, and probably also the coalescence, or more correctly the non-separation, of the tuberculum and capitulum on the hinder ribs; as the rather large, ossified costal cartilages ; as the rather well-developed sternum ; as the presence of the first finger, the meta- carpal at least of which is found; as the rather slight lengthening of the middle fingers, etc. In one single direction the known Platanistids have developed themselves highly. They have used the jaws as a kind of delicate forceps to seize and hold prey that did not make very strong resis- tance. The jaws grow to an unusual length but become noticeably slender, fine, though solid. The intermaxillary and maxillary press close together, covering over the anterior part of the mesethmoid, and they have a tendency to coalesce. The maxillary has pushed itself forward anteriorly beyond the tip of the intermaxillary. In the lower 20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 jaw the symphysis menti becomes very long, and the rami of the mandible are inclined to grow together. The teeth that lie at the front of the jaws are inclined to increase in size, probably because the tips of the jaws come to be the most used part of the forceps. In another respect also the known Platanistids stand high: the sides of the facial depression are inclined to grow upward. Perhaps they also stand high in the tendency of the pterygoid to widen itself out unusually far backward in the outer wall of the air-sac behind the palate, reaching back to the squamosal; a circumstance that may call to mind both lower and higher whales, Baleenids and Physeterids.* The genus of Platanistids which has removed itself least from Squalodon appears to be the Tertiary South American Pontistes, which is known from most of the skull. In relation to one or another of its nearest allies it has the following primitive characters : the teeth, judging from the alveoli, were small, simply formed, the anterior not enlarged ; the toothrows stand rather distant from each other, as the palate is relatively broad; the outer margin of the facial depression, especially the longitudinal crest on the maxillary above the orbit, is relatively low. A character which must be considered advanced in comparison with the nearest relatives is the specially large number of teeth, about 40 in each jaw if one judges rightly from the fragments of toothrows that have been found. Near to Pontistes but on a slightly higher level is Pontoporia (Stenodelphis). The teeth have become smaller but more numerous, about 55 in each jaw. Those in front have a slight tendency to be enlarged. The toothrows are placed nearer together and the palate is narrower. A high specialization, which also holds good for the other recent members of the family, is the complete absence of the olecranon. Lipotes (known from external characters, skull, and cervical verte- bre) and Jia are near relatives of Pontoporia. Their face is shorter, the number of teeth is less (about 30 in each jaw in the former, about 26 in the latter), the anterior teeth show scarcely any tendency to be enlarged. It might appear as if the two genera were, in these char- acters, less specialized; but the explanation is presumably another. The two genera most likely originated from forms that more nearly resembled Pontoporia, and that had the strongly narrowed palate and numerous small simply conical teeth, although not so many as in Pontoporia. Lipotes and Inia appear to have used the teeth in a special manner, most probably for the crushing of food, and the teeth have therefore regained some of their earlier strength, have grown no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 27 and become massive, with wrinkled enamel. In compensation, how- ever, they have become less numerous and the most posterior in the jaws have acquired a form which is anything but primitive: the base of the crown is more or less tubercularly widened out inward. The narrow palate is retained. The lateral margin of the facial depression is considerably more upturned than in Pontoporia, and the posterior border, especially in the median region formed by the frontal, is far more elevated. Lipotes as compared with nia is surely the more primitive in the greater slenderness of the teeth; on the contrary it is the less primi- tive in having the facial depression relatively strongly widened behind. Saurodelphis (Saurocetus, Pontoplanodes), Tertiary, Argentinian, known from most of the skull, appears to have also originated from Pontoporia-like animals, but it has gone in another direction than Ima. It has retained the slender face with the narrow palate, but the number of teeth is reduced to about 20 in each jaw. At the same time the teeth are enlarged ; in any event they have acquired roots that are more widened antero-posteriorly ; this is especially true of a number of the anterior teeth in each jaw. In these teeth the root appears to be in process of dividing in two, so that in cross-section it is almost 8-shaped, a form which, especially as regards the anterior teeth, is quite the opposite to primitive. The lateral margin of the facial de- pression is trenchant and highly upraised, even more than in Jnia. The hinder margin of the depression is not only elevated in the middle as in Ima, but is also pushed further back. Platanista also probably traces its origin back to Pontoporia-like creatures. It has gone further than any other member of the family in the direction of making over the jaws into delicate forceps. The face is so slender and the palate so narrowed that the right and left toothrows in the upper jaw lie closely side by side; they may even, especially at the extreme rear, where the teeth are undergoing atrophy, be pushed into each other. Somewhat similar conditions obtain in the lower jaw. The number of teeth is about 30 in each jaw. Several teeth at the front of each jaw have acquired high, pointed crown and compressed, enlarged root. The outer margin of the facial depression has grown upward, higher than in any other genus, especially that part of it which runs along the outer margin of the maxillary over the orbit and front of the temporal fossa. This part has shaped itself quite fantastically as a huge plate which rises high upward and bends in over the posterior part of the face, which it covers like a mask, since each plate nearly meets its fellow from the 28 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 opposite side. On the other hand the posterior margin of the depres- sion is not particularly highly elevated. The eye is atrophied ; touch more than vision probably guides in the capture of prey. The hand’s unusually broad, rounded-off outline, with the especially short, uni- form, well-developed and wide apart fingers, might appear more primitive than in other members of the family; but possibly it may be the story of a partial reversal from an earlier more flipper-like condition.

Delphinide.—The most important character—perhaps in the beginning the only one—which has separated the Delphinids from the most primitive Platanistids from which they sprang is the widen- ing out of the facial depression. This broadens posteriorly to such an extent that its floor wholly covers over the temporal fossa like a roof formed by the frontal and maxillary together. A second no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 29 peculiarity, which in any event soon showed itself, is the reduction of the temporal muscle through lack of use; its fossa becomes smaller and the zygomatic process of the squamosal becomes less projecting and less robust, losing, moreover, its primitive arched form. In the more advanced members of the family many other modifications may appear. The facial part of the skull, which begins by being long and narrow, almost compressed, used as forceps, may become still longer. Or the use as forceps may grow less and be exchanged for service as an implement for rooting in the sea bottom; followed by alteration in the form of the face. Or the mouth is used merely to clap together around the prey; followed by flattening and shortening of the face. In each instance the facial cushion contributes to the flattening of the facial part of the skull. The extreme tip of the intermaxillary has the tendency to be restricted, to be grown over by the maxillary and to lose the teeth which at first were implanted in it. Its upper margin may extend in over the anterior part of the mesethmoid and coalesce with its fellow of the opposite side. The symphysis menti has a tendency to be weakened and shortened. The teeth are inclined to a further reduction, and they may disappear; but they may also be again applied to special work and be modified in various ways. The braincase increases in size and is more subject to pressure from in front and from behind. The nasal passage may be pushed further back. The nasal bone, which in the most primitive Delphinids retained a slight trace of its earlier function as a cover for the nasal cavity, becomes in most cases quite sunk into the frontal. The occipital condyle, which at first is rather projecting in the usual manner, becomes flattened out and pressed in against the wall of the braincase. The cervical vertebrzee may coalesce. The thoracic verte- bree acquire unusually long transverse processes which are especially noticeable on the hindmost of the series. Most of them are dia- pophyses except the most posterior ones; these are parapophyses. Only the anterior ribs retain the capitulum. On the hindmost ribs the capitulum disappears entirely, and the rib is articulated with the tip of the long transverse process by the tuberculum only. (As in the Platanistids the single articular head on the very hindermost ribs is presumably formed by the capitulum or by the capitulum and tuber- culum undivided.) The flippers may be lengthened. Etc. The ptery- goid varies capriciously. It is true that it always spreads inward under the posterior nares ; but it is sometimes rather widely separated from its fellow of the opposite side, sometimes almost in contact with it, while probably after having been in the latter condition it may 30 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 withdraw. The number of vertebrz also varies in a quite capricious manner. One of the most primitive Delphinids is no doubt the Tertiary North American Delphinodon, the skeleton of which is known rather completely. In comparison with its various relatives it has the following primitive peculiarities. The teeth are present in large numbers. They are small and nearly simply conical, some of them, however, with wrinkles or small projections on the base of the crown, probably mementos of the crown’s formerly serrate margins and of its also otherwise less simple form. The facial part of the skull is rather long and narrow. As in the related forms which are lowest in this respect the anterior end of the intermaxillary was probably freely projecting, tooth bearing, and not grown over by the maxillary. The upper margin of the intermaxillary does not come in contact with its fellow. The symphysis menti is long; nasal slightly projecting ; cervical vertebrz distinct. It shows a peculiarity of its own in having a longitudinal crest on the projecting lateral part of the basioccipital. The Tertiary European Champsodelphis (judging chiefly from Ch. ombonit, Acrodelphis) presumably stands near to Delphinodon. It is known from scarcely anything else than scanty remains of the skull. It shows high specialization in the modification of the rostrum to serve as an implement for boring or rooting in the sea bottom. The facial part of the skull has acquired an unusual length and slenderness; the teeth have probably disappeared from the inter- maxillary, and the upper margin of this bone was probably in contact with its fellow through a considerable part of its extent. , The Tertiary European Schizodelphis (judging from S. sulcatus, Cyrtodelphis), also known practically from the skull only, must be a near relative of Champsodelphis with which it appears to have most of its peculiarities in common, both the primitive characters and the special modifications. Its most important difference appears to be that its teeth have gone still further in the direction of simplicity ; the only reminders of earlier, less reduced form that have remained behind are a slight widening out of the crown’s base, which may be found on some of the teeth, and the trenchant character of its anterior and posterior margins. The Tertiary European Heterodelphis, which is known from rather considerable parts of the skeleton, undoubtedly stands close to Schizo- delphis. Its teeth have become still more simple, with purely conical crowns. no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 31 In the Tertiary European Eurhinodelphis, which is known from most of the skull and from parts of the rest of the skeleton, the transformation of the snout into a rooting implement has reached the highest limit. The rostrum, both upper jaw and lower jaw, has grown forward anteriorly as a long slender point, still more notice- ably than in any of the other genera. The intermaxillary has ex- tended itself, awl-shaped and toothless, far forward beyond the maxillary. The tip of the lower jaw appears to be formed in a corre- - sponding manner. The teeth are simply conical. No doubt the Tertiary South American Argyrocetus is very nearly related to Eurhinodelphis. It is known from a defective skull, and appears to differ in trifles only. The genera just mentioned of the group Eurhinodelphini form a contrast with the group Monodontes. The latter includes the genera Delphinapterus and Monodon, which must have originated from the oldest Eurhinodelphines in which the tip of the snout had not been remodeled as a rooting implement. In common with the Eurhino- delphines (at least with Delphinodon, Heterodelphis, Eurhinodelphis, and Argyrocetus, which are known in this respect) the Monodonts alone among the Delphinids have the primitive character that the cervical vertebree are mutually independent. Other indications of low origin seem to be shown by the Monodonts in the form of the teeth (in which one of the genera may recall Delphinodon and others), in the decidedly short spinous and transverse processes of the thoracic vertebrze, in the relatively short fingers, and perhaps also in the absence of the dorsal fin. But in the flat and broad form of the face, probably resulting from their habit of not using the jaws for _ much else than to clap together on tender cuttlefish, the Monodonts are more highly developed than their progenitors among the Eurhino- delphines. The same is true of their lack of the olecranon.” The most primitive of the known Monodonts is Delphinapterus. It shows its primitiveness in relation to its nearest ally by its rather ordinary dentition: the teeth are present in relatively considerable numbers, about Io in each jaw; they are small and conical, but in the upper jaw they are directed forward in a peculiar manner. The teeth have disappeared from the intermaxillary. In Monodon the teeth, with a single exception, are in process of atrophy and disappearance; only a few of them are present in the young. One of the foremost teeth in each maxilla has had its peculiar destiny: it has grown forward as a “ramming-tooth,” at first no doubt uniformly in the right and left jaw and in the male and female, 32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 probably used, in a similar manner to the upper canine in the walrus or to the tip of the snout itself in the Eurhinodelphines, for rooting in the sea bottom. Such a function might be initiated by forward- slanting anterior teeth like those in Delphinapterus, but later it must have been restricted to the ramming-tooth in the left jaw of males. The work of the males may possibly be of service to the females because the species is gregarious. The ramming-tooth has become a _kind of male secondary sexual character and has grown to an ex- aggerated size as the well-known “ unicorn horn.” As a memento of an earlier condition the ramming-tooth is still found in a reduced form in the right upper jaw of the male, and in both upper jaws of the female; in rare instances it may even now be found in the male well developed on both sides | when the spiral of the two tusks is parallel]. All the other Delphinids are contrasted with the Eurhinodelphines and Monodonts by the partial or complete coalescence of the cervical vertebre, the atlas and axis being always united. The genera in question constitute a compact group, rich in forms, which traces its origin back to low Eurhinodelphines. Lowest of all stands the section Delphini, whose most primitive known genus is undoubtedly Steno. This has still the primitive Eurhinodelphines’ long, but not exaggeratedly long, narrow, scarcely flattened fore-face, with long toothrows and long symphysis menti. It is indeed scarcely distinguishable from the primitive Eurhinodel- phines except by its partly ankylosed cervical vertebrae. The circum- stances which place it low among its nearest relatives are the facts that the teeth have fluted enamel, and that the symphysis menti is long. The peculiarity of the enamel is presumably a slight reminis- cence of an earlier, less-reduced condition. Very near Steno comes Prodelphinus (probably including “ Sota- lia’’), not differing in much else than that the enamel is smooth, not fluted, and that the symphysis menti is shortened. Delphinus differs from Prodelphinus in scarcely anything else than a peculiar palate form: at the inner side of the toothrow the bony palate is hollowed out into a long longitudinal furrow which is especially deep behind. The intermaxillaries have a relatively strong tendency to coalesce and to cover over the mesethmoid. A few small teeth may be found in the intermaxillary as in Steno and Prodel- phinus; in most of the Delphinids the teeth have wholly disappeared therefrom. In contrast to the Delphinines the other higher Delphinids have the skull’s fore-face shorter and more depressed. As a beginning the no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 33 difference is only slight, but it finally increases so as to become very noticeable. At the same time that the anterior facial part of the skull is shortened, because the mouth is no longer used as a pair of forceps but as a “clap-trap,” it becomes flatter and broader, while its upper side is more pressed upon by the facial cushion. The cushion becomes larger, especially widening itself out anteriorly and pushing into the originally slender “beak.” The intermaxillaries, in their anterior portion particularly, together lose their structure as an upstanding roof-ridge, and finally become quite flat, each of the bones widened out. The genera of the section Legenorhynchi depart so slightly from the more primitive members of the section Delphini, such as Pro- delphinus, that there would scarcely be any reason to set them apart in a special group were it not evident that they represent the begin- ning of new series of forms. Doubtless Tursiops occupies the lowest position. The anterior facial part of the skull is indeed broader than in Prodelphinus, but it has, however, not lost its form as a roof-ridge, and it has still a considerable length. Near Tursiops probably belongs Tursio [Lissodelphis|, which also has the fore-face rather long, though more flattened. Another difference is that it lacks the dorsal fin, either because it has lost it or has never acquired it. Lagenorhynchus (to which should probably be joined Cephalo- rhynchus and Sagmatias, and perhaps “ Feresa”) has gone a step further than Tursiops and Tursio in the direction of shortening and flattening the rostrum. Among the Delphinids in which the process of shortening and flattening the rostrum has been more perfected the members of the section Globicipites are contrasted with those of the section Phoceenz by reason of their greater primitiveness. In them the crowns of the teeth have retained their primitive conical form, while in the Pho- ceenans the crowns have become entirely peculiar. Orca [Orcinus] is the one among the Globicipites which has retained most of the ordinary dolphin type in the structure of the rostrum, particularly as regards the narrowness of the intermaxillary. The rather short, rounded-off form of the hand might appear to be primitive also, but various circumstances strongly indicate that it has arisen through the shortening of an ordinary, pointed, porpoise flipper: the number of phalanges in the second finger is rather large; the finger is merely more strongly arcuate than usual. In the trans- formation of the dentition to a conspicuously powerful biting imple- 34 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 ment Orca has gone further than any other genus of the family. It has habituated itself to living on large prey such as seals and the smaller cetaceans, and it even slashes into the largest. The teeth are, it is true, relatively few, about 12 in each jaw, but in compensation they are massive. Orcella has reached higher than Orca in the great breadth of the intermaxillary, but it must have originated at a level lower than that on which Orca stands, sinte its teeth are small and rather more numerous, while its hand is essentially like an ordinary porpoise hand. The genus gives the impression of being a dwarf form with notice- ably large braincase in proportion to the face. The following genera of Globicipites must have originated from Delphinids that were essentially like Orcella but without the dwarf- ing. Each has gone its own way. There is, however, one peculiarity that unites them: the hand has acquired an uncommon length and narrowness, though in different degrees, at last with an unusual number of phalanges in the second finger. In “ Grampus”’ the intermaxillary has retained a breadth similar to that in Orcella. Although the hand is long and narrow there are only about eight phalanges in the second finger. The chief peculiarity of the genus lies in the atrophy of the dentition: only a few and rather small teeth remain. These are at the front of the mandible, and with age they may entirely disappear. In Pseudorca the hand is essentially as in Grampus. But the inter- maxillary has acquired a very noticeable breadth anteriorly, and the dentition is developed in a similar manner as in Orca. The intermaxillary is conspicuously wide in Globiceps [ Globi- cephala| also; it may be even wider than in Pseudorca. Peculiarities of Globiceps are: that the nostril is pushed unusually far backward, that the dentition is atrophied so that only a few, about 10, small teeth remain, situated at the front of the jaws, and that the hand is conspicuously long, with as many as 14 or more phalanges in the second finger. The section Phocene presumably originated among the most primi- tive Globicipites or perhaps Lagenorhynchi. That which places this group in contrast not only with the Lagenorhynchi but also with all other Delphinids is the peculiar form of the teeth. The teeth are present in large number and are of small size. Some of the foremost and hindmost may have about the usual conical crown, and all of them are single rooted. Most of the teeth, however, have the crown com- pressed, widened out fan-wise or leaf-wise, and often with notches in No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 35 the margin; a form which is not only unique among the cetacea, but the contrary to the forms found among the most primitive cetacean genera.” Phocena is, besides, a little broad-snouted porpoise, rather evenly developed in all directions. A few small teeth may be present in the intermaxillary. Neomeris (Neophocena) is nearly related to Phocena. It differs in having acquired a yet shorter and broader face, in having a notice- ably spacious braincase, and in lacking the dorsal fin, which it doubt- less has lost. Delphinide.” I.

Physeteride.—The Physeteride probably originated from the most primitive Delphinids, from Delphinids in which the margin of the facial depression must have been so widened that it covered the temporal fossa, but which at the same time retained these primitive features: zygomatic process of the squamosal relatively large and somewhat arcuate; teeth small and conical, but still with traces of - notching on the margin of the crown; teeth in the intermaxillary well developed ; anterior part of mesethmoid free, not covered over by the intermaxillaries; free though stunted lacrimal; separate cervical vertebre ; rather short transverse processes on the thoracic vertebree ; a well-developed capitulum on all the ribs, etc. The character that already places even the most primitive Physeterids on a higher plane than the Delphinids is a result of stronger action of the facial cushion. It appears as if the Physeteride had from the very first trained them- selves to swifter, more violent swimming than other whales, and that the fat-pad in front of the nose had therefore been pressed in with greater force against the facial part of the skull. The pad, together with the nasal muscles, etc., has modified the face to an unusual degree. Especially the posterior margin of the facial depression is transformed, more or less conspicuously elevated. The crookedness 38 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL..72 in the posterior nasal passage and in the facial bones becomes more conspicuous than in other whales. The resistance of the water has acted upon the skull in other ways also, different in the different groups; there is a tendency toward strengthening and coalescence of the bones of the face, toward the appearance of projecting osseous protuberances, etc. The members of the family, so far as they are known in this respect, show a peculiarity in the relation between the ribs and the transverse processes on the posterior thoracic vertebre, in which they form a contrast to at least the living forms of Delphinids. While in the Delphinids the hinder ribs apparently lose the capitulum and retain the tuberculum (the most posterior, probably having their own history, have never had more than a single head), in the Physeterids it is the tuberculum that disappears, while the capitulum remains. On one or two of the hindmost ribs it may happen that the capitulum and tuberculum can be seen at the same time, each in contact with its “transverse process”’; but the tuberculum with its corresponding process, a diapophysis, is in course of atrophy.” The genera of the section Xiphiini stand lowest. In them the occipital wall, which forms the posterior margin of the facial depres- sion, is highly elevated in a section at the middle only, behind the nares, and is not pushed very far back in relation to the nares. In the con- trasted Physeterini the occipital wall is heightened through its whole extent and more pushed backward. Likewise a primitive feature of those Xiphiines that are known in this respect is that a more or less distinct lacrimal bone is present, though in an atrophied condition, spreading out especially in the roof of the orbit. The essentially most primitive genus of the Xiphiines is no doubt the Tertiary South American Argyrodelphis (Notocetus, Diochoti- chus), of the group Argyrodelphini, not known from much else than the skull. It stands lower than all other known Physeterids in having a relatively robust and arcuate zygomatic process of the squamosal and in the character of the dentition. There is a long row of small, well-developed, conical teeth in both upper and lower jaw, some of them bearing notches on the margin of the crown. On the contrary, as compared with one or another of the other genera, it is advanced in having the occipital wall pushed rather far back, in having a rather large cushion-shaped outgrowth on the maxillary above the orbit, and in having the intermaxillaries spread inward over the mesethmoid and coming into mutual contact with age. The cervical vertebre were free. no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 39 In all other Xiphiines the zygomatic process of the squamosal is smaller and more atrophied, the teeth in the upper jaw disappear, while of those in the lower jaw one or two only remain in each ramus and these are particularly modified. A peculiarity of at least the living forms of the section is the unusual size of the air-sac at the outer side of the pterygoid, which is shaped to fit it. Somewhat of a peculiarity likewise is partly the height of the spinous processes on the dorsal and caudal vertebre (while the transverse processes are relatively rather short), and partly the small size of the hand. The former character indicates unusually heavy dorsal and caudal muscles, or perhaps a widening out of the muscles in a different direction— more upward than sideways—than in the Delphinids with specially long transverse processes. The latter makes it appear that the hand is somewhat disused. The cervical vertebre are inclined to coalesce as in the Physeterines. In the members of the group Xiphii, as contrasted with the Hyperoodontes, the bones of the face have remained primitive to the extent that no raised longitudinal crest is present on the maxillary in front of and above the orbit ; at most there is found in the correspond- ing place a weak cushion-shaped elevation. But in other ways the bones of the face have increased in strength and have permitted them- selves to be moulded by the pressure of the water. In a few respects Mesoplodon is the most primitive among the Xiphi. To be sure, the facial cushion, by pressing back against the occipital wall, has caused the median part of the wall, formed for the most part of projecting outgrowths of the intermaxillaries, to be abruptly elevated. But*the cushion has not acted on the wall to such a degree that the upper margin together with the nasal bones has been either very strongly forced back or caused to bend forward in any noteworthy manner; neither has it formed for itself any distinct pit around the nares. Moreover the intermaxillaries have retained their original relation to the mesethmoid, which they do not grow over. On the other hand the rostrum acquires increased strength by the ossification, as age advances, of the mesethmoid, and its coalescence with the surrounding bones into a stony-hard mass. Of the teeth in the upper jaw there is found in Mesoplodon at most a series of quite small remnants, more or less hidden in the skin and scarcely leaving any traces in the bones. In the lower jaw there is found only one well-developed tooth. This is situated at the front of the mandible and is peculiarly modified, having a large, compressed crown and a big root which sometimes, presumably in the male especially, may AO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 grow to a disproportionate size and to a high degree affect the form of the jaw. The Tertiary European Xiphirostrum (“ Ziphirostrum,’ “ Miozi- phius”), which is known from parts of the skull, has in a single respect gone further than Mesoplodon, near to which it otherwise stands: the intermaxillaries have grown over the mesethmoid and come in contact with each other along their upper margins. But Xiphirostrum must have taken its origin from whales that were less far advanced than the known species of Mesoplodon; as the mes- ethmoid is not ossified anteriorly; the teeth in the upper jaw are slightly less atrophied, leaving traces behind them in the maxillary ; and at the front of the lower jaw there are two well-developed teeth on each side. Chonoxiphius (“ Chonesiphius’’), likewise Tertiary European and known from parts of the skull, stands near to Xiphirostrum. It has gone further in the modification of the face. The facial cushion has begun to modify a special area around the nares for its bed. Here the lateral margins of the premaxillaries are caused to grow slightly upward, so that they together, and the bones that lie between, form a special pit, a structure the first traits of which, more or less evident, are found in many other toothed cetaceans. In the middle of the pit there has arisen an erect longitudinal crest, evidently formed from the posterior part of the mesethmoid. (The under jaw is probably not known. ) Xiphius (“Ziphius”) appears to have originated from whales which stood on about the same level as Mesoplodon. Its deviations are of two principal kinds: (1) the median part of the occipital wall is forced further back and raised higher upward, so thatthe nasal bones, which are even more modified than in other Xiphiines and are widened out plate-wise in front, once more come to form a forward- bent roof over the nasal cavity, and (2) the lateral margins of the intermaxillaries have grown upward as in Chonoxiphius, but much more conspicuously, bounding a deep pit. As in Mesoplodon the anterior part of the mesethmoid becomes ossified with age. In the genera of the group Hyperoodontes, which must have originated from the lowest Xiphii, the bony crest, a faint indication of which is found in many toothed cetaceans running along the upper surface of the maxillary in front of and over the orbit, becomes so stimulated to growth by resistance of the water that it gradually swells up to a huge hump which spreads itself over most of the face in front of the nares. Each hump is closely appressed to its fellow no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE Al of the opposite side, leaning inward over the intermaxillary and mesethmoid so as to turn a broad shock-receiving surface forward. The nares and middle part of the occipital wall are forced unusually far backward toward the posterior boundary of the braincase. The most primitive genus of the group is “ Berardius.’ The longitudinal crest on the upper surface of the maxillary is well developed and erect, but the face, however, has retained essentially its ordinary form. At the front of the lower jaw are found two rather well-developed teeth. In Hyperoodon the face becomes with age wholly abnormal, since the longitudinal crest on the maxillary elevates itself to a height which exceeds even the highest part of the occipital wall. In the lower jaw at the front is found only a single tooth (apart from embryonic conditions). The genera of the section Physeterini must have originated among the most primitive Xiphiines, from Xiphiines in which the dentition was still rather well developed, with teeth in the intermaxillary as well as the maxillary; in which the intermaxillaries were free from each other and from the surrounding bones ; in which the mesethmoid was not ossified, etc. Their peculiarity is that the pressure of the facial cushion on its surroundings acts differently than in the Xiphiines, and even more strongly. The facial cushion, especially that part of it which is formed by the adipose mass, widens out still more, particularly outside of and behind the nasal passages. It pushes the median part of the occipital wall far back behind the nares, while at the same time the margins of the facial depression, at the back and at the sides, grow high upward. The bones which form the bottom of the facial cushion’s bed are strongly acted upon by the stimulating mass of the cushion. They widen out. This holds good especially of the bones in the rostrum, and chiefly of the anterior part of the maxillary. The lower jaw on the contrary retains its primitive narrowness. The genera of the group Hoploceti are extinct, Tertiary, and are only incompletely known, chiefly from fragments of skulls. It may be concluded that the skull in essential respects is modified in the same manner as in the highest group of Physeterids, the Physeteres, but to a distinctly less noticeable degree. They are also less advanced than the Physeteres in the development of the dentition, there being a long row of well-developed teeth in both upper and lower jaws, while the upper teeth of the Physeteres have atrophied. 42 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 In the European and American Hoplocetus (Balenodon, Physodon, “ Scaldicetus,”’ etc.) the teeth are covered with enamel. The European Physeterula has lost the enamel, it appears. In the genera of the group Physeteres the influence of the facial cushion on the skull has led to fantastic results. The dentition also is modified in a strange manner. In the lower jaw the teeth continue to be well developed; but in the upper jaw they atrophy and dis- appear either wholly or essentially so. It is not clear what the reason can be for this difference between the upper and lower jaws. Per- haps the difference is connected with the great lateral broadening out of the maxillary whereby the upper toothrows are so pushed outward that they lose their interaction with the lower toothrows which retain their ancestral position in the closely appressed mandi- bular rami. There has been no hard work for the upper teeth which might have maintained them in spite of all; the lower teeth together with the palate must have proved sufficient, as the task is indeed scarcely anything else than to grasp the cuttlefish which appear to be the favorite food for this whole family as well as for various other cetaceans, especially for those with more or less degenerate dentition. “ Cogia”’ is in some respects the most primitive of the genera. In the upper jaw there is still found, or may be found, a tolerably well- developed tooth. In the skull there remains a rather considerable, curved remnant (although very narrow and compressed) of the heightened osseous ridge which elsewhere in the toothed whales lies between the nares and the occipital wall; the adipose cushion has not yet wholly destroyed it. Neither has the cushion so grown around the outer nasal passage that it has pushed the orifice away from its accustomed place, nor has it to any noticeable degree pressed the roof of the braincase down. The anterior part of the face has become broader than usual, but it is still rather short, or, more strictly speaking, has been further shortened. On the other hand the lateral margin of the facial depression, over the braincase, is pushed unus- ually far out to the side and raised conspicuously high upward; it has also acquired a unique thickness. In Physeter nothing has remained of the upper teeth except small vestiges hidden in the skin. The fat-cushion, which has grown gigantically, has caused the bones of the rostrum to grow far forward and to broaden themselves strongly at the side. The posterior margin of the facial depression is more abruptly elevated than in any other whale and is pushed further back. The fat-cushion has completely overgrown and leveled off the bony wall which elsewhere lies be- no. 8 INTERRELATIONSHIPS OF THE CETACEA—-WINGE 43 tween the nares and the occipital wall. The soft outer nasal passage is pushed forward so that the blow-hole lies far to the front. The adipose cushion has forced the roof of the braincase down by its weight, and the whole braincase has sunk down below its original level, so that the spinal marrow, or medulla oblongata, has to bend down in an S-shaped curve to connect with the brain. The skull has acquired a noticeably large size in proportion to the body, and most of its bones have become conspicuously ponderous ; this is especially noticeable as concerns the zygoma. Just as Physeter is the largest of all the toothed whales and pushes through the water with greater force than any other, it is the one on which the resistance of the water has had the most powerful influence. But it is a question whether this high development is not a menace to the creature’s life. Irresistibly the water’s pressure has caused the facial cushion to grow to a disproportionate degree and in its turn to call forth a skull the size of which is without relation to brain and body. The fate of Physeter, the most highly developed toothed whale, is much like that of Balena, the strangest whale-bone whale; the difference is that the pressure of the water in the one has acted most strongly on the outer side of the head, in the other most strongly on the inner walls of the mouth. Both animals are developed with such extravagant one- sidedness that they appear to be in danger of certain extinction even if their extirpation were not being worked at by man. Physeteridz.” I.

They had spread over Europe and North America and were found in northern Africa as well. The whales must have made their appearance somewhere within the territory occupied by the Hyzenodonts, and probably in the oldest part of the Tertiary; in agreement with this the most primitive cetacean that is yet known, the Hyznodont-like Protocetus of the family Zeuglodontidz, is found in Egypt in Eocene strata. Likewise one of the next links in the chain of cetacean development, Prozeuglodon, was Egyptian, from the Eocene. But soon the mem- bers of the family must have spread widely ; in any event the highest genus, the almost fantastic, snake-like Zeuglodon |Basilosaurus}, appears to have found its way during the Eocene to all oceans. The Zeuglodonts died out early in the Tertiary. Their highest forms left no descendants; but from the more primitive genera of the family sprang the new family Balznide. The oldest, tooth- bearing forms of Balznids are as yet scarcely known. In Miocene times, however, the family had already produced the specialized whalebone-bearing forms, a side branch on the cetacean genealogical tree, and they soon spread themselves to all the seas of the globe, where they still are found. Some of the recent genera are essentially cosmopolitan, even in the sense that individual species occur in all seas. This holds good in part only of Balena, one of whose species, the more primitive, B. australis, is almost cosmopolitan, while the second, the more specialized, B. mysticetus, is confined to the northern polar oceans. It is literally true of Balenoptera and Megaptera. _ Two of the recent genera are confined to a smaller range: Neobalena a relatively high genus that lives in the South Sea, where it likely originated, and Rhachionectes a relatively low genus, in many respects recalling extinct Miocene forms. It lives in the northern part of the Pacific, perhaps as a kind of last remnant from an early day. The reason why the Balzenids, in spite of their rather primitive structure, are not wholly extinct, supplanted by the more specialized cetacea, is probably because they have chosen a peculiar food supply: the small creatures of the sea. Therefore they do not have very many competitors among their kind. From the most primitive, tooth-bearing Balznids the family Squalodontidze branched off in Tertiary times. It had its flourish- ing period in the Miocene, widely distributed in the oceans. The whole family disappeared before the end of the Tertiary, chiefly, it would appear, because it passed onward into its successors. 40 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL 72 The descendants of the primitive Squalodonts are the members of the family Platanistide which appeared early in the Tertiary and was soon widely distributed. Most of the genera have died out again; only four, Pontoporia [Stenodelphis|, Lipotes, Inia and Pla- tanista, have come down to the present time. These have doubtless avoided being crowded out by higher cetaceans purely because they have chosen a peculiar habitat, rivers and estuaries, which they have been almost alone in utilizing. Early in the Tertiary the family Delphinidz branched off from primitive Platanistids. Extinct genera, especially in the Miocene, are known from localities that were even then far apart; at present the family is universally distributed, many of the genera and species being nearly cosmopolitan. The family seems to be having its flourishing period now. Only a few of the recent genera have ranges that are somewhat restricted, as Delphinapterus and Monodon in the Arctic Ocean, Tursio [ Lissodelphis| in the Pacific, Orcella in the rivers of Southeast Asia and in the neighboring sea, Neomeris | Neophocena] on the eastern and southern coast of Asia and the east coast of Africa. Early in the Tertiary the family Physeteridz originated from the most primitive Delphinids. It had already reached its climax in the Pliocene, widely distributed. Only rather few genera, but these very highly developed, have come down to the present day. They are widely distributed, essentially cosmopolitan. no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 47 NOTES *(P. 1.) The present treatise on Cetacea is a continuation of the series of memoirs on the other orders of mammals which have appeared in E Museo Lundii, vols. 1-3, 1887-1915, and in the Vidensk. Medd. Dansk Naturhist. Foren., vol. 68, 1917. Part of the opinions that are here expressed have been previously published in the Vidensk. Medd. Dansk Naturhist. Foren. for 1882, pp. 29-31, 40 and 53-55; tbid., for 1909, pp. 5-9; Meddelelser om Gr¢gnland, pt. 21, 1902, pp. 364-368 ; Danmarks Fauna, Pattedyr, 1908, pp. 9-10, 200-209. *(P. 1.) On the origin of the Cetacea very different opinions have been put forward. The idea of Brandt and others that the Cetacea are the lowest, most reptilian mammals is now shared by scarcely any one. Likewise the old idea of the relationship with sea-cows was long ago laid aside. Flower’s early opinion that the whales originated from seals, an opinion which he shared with others, was disputed by Winge (Vidensk. Medd., 1882, pp. 53-55) and almost abandoned by Flower himself. It was not taken up by others except in a way by D’Arcy Thompson. D’Arcy Thompson’s opinion (On the Systematic Position of Zeuglodon; Studies from the Museum of Zoology in University College, Dundee, vol. 9, 1890, pp. 1-8, with illustrations) that the Zeuglodonts, really the most primitive whales, are not Cetacea, but near relatives of the seals, is disproved by Lydekker (Proc. Zool. Soc. London, 1892, pp. 560- 561) and Dames (Ueber Zeuglodonten aus Aegypten, etc. ; Palaeont. - Abhandl., herausgeg. von Dames u. Kayser, vol. 5, pt. 5, 1894, section pp. 204-210). Flower’s ideas about the whale’s relationship to par- ticular ungulates proper other than sea-cows have also shown them- selves to be incorrect. The author who has most extensively ex- amined the question in earlier times is Max Weber in his book: Studien uber Saugethiere, ein Beitrag zur Frage nach dem Ursprung der Cetaceen, 1886, which contains a review of earlier work on the subject. His own conception of the history of the Cetacea was then “dass sie einem generalisirten Saugethiertypus im mesozoischem Zeitalter entstammen, der zwischen Carnivora und Ungulata mitten inne steht, wohl aber nahere Beziehungen zu Carnivora hatte” (J. c., p. 241). In his work Die Saugethiere, 1904 (p. 581), Max Weber sets forth the idea that “ primitive Condylarthrer ”’ were perhaps most nearly the precursors of the whales. 48 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Solid ground was first reached with the discovery of Protocetus atavus described by Fraas (Neue Zeuglodonten aus dem unteren Mitteleocan von Mokattam bei Cairo; Geol. u. Paleont. Abhandl., herausgeg. von Koken, vol. 10, pt. 3, 1904. There could be no doubt that Protocetus came from Hyznodonts and that it was itself a fore- runner of the Zeuglodonts. Curiously, however, Fraas thought that the origin of the Cetacea was not thereby explained. He considered both Protocetus and with it the other Zeuglodonts as a side branch from the carnivores which did not lead in the direction of the true whales. There seems now, however, to be unanimity of opinion that Protocetus, Prozeuglodon, etc., are some of the long sought pro- genitors of the whales. In spite of all differences from the higher Cetacea there is a multitude of resemblances to them which it would be impossible to explain except on the basis of relationship. One has only to think of the striking likeness in such peculiarly formed bones as the tympanic and scapula ; their characters in the fossils are exactly those that one would expect to find in ancestral Cetacea. It has been said that the whalebone whales and the toothed whales might have separate “‘ diphyletic”’ origins; Kukenthal in particular has spoken for this view (Ueber die Anpassung von Saugethieren an das Leben im Wasser ; Zool. Jahrbucher, Abth. fiir Systematik, etc., vol. 5, 1891, pp. 373-399, especially p. 384, and elsewhere). In face of the host of agreements in numerous structural relationships which are found in the two groups this idea is an impossibility. Just one little bone like the tympanic, with its thickened inner wall, its mussel- shaped outgrowth around the outer auditory aperture, its petrous process which reaches out under the mastoid, and other details, all of the most peculiar form, and all essentially identical in all Cetacea, is sufficient evidence of the near relationship of all whales. Kukenthal has put forward a “‘ Versuch, den Bau des Walkorpers von biologischen Gesichtspunkten aus zu erklaren,” most elaborately in Die Wale der Arktis, Fauna Arctica, vol. 1, pt. 2, 1900, section pp. 181-203. * (P. 3.) We owe to Abel a special treatise on the skeleton of the hind limb in Cetacea: Die Morphologie der Hiiftbeinrudimente der Cetaceen; Denkschr. d. math. -naturw. Klasse d. k. Akad. d: Wissensch. Wien, vol. 81, 1907, pp. 139-195, with illustrations. A supplement is given by Lonnberg: The Pelvic Bones of Some Cetacea; Arkiv for Zoologi, vol. 7, No. 10, 1910, pp. 1-15, with illustrations. No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 49 *(P. 4.) Much information about the structure of the hand in the Cetacea has been collected by Kukenthal (Die Hand der Cetaceen ; Denkschr. d. med. naturw. Ges. zu Jena, vol. 3, pt. 1, 1889, pp. 23-69, pl. 3, and the section “ Die Brustflosse,” in Vergl. -anat. u. entwicke- lungsgesch. Unters. an Walthieren, ibid., pt. 2, 1893, pp. 267-312, with illustrations) and Kunze (Ueber die Brustflosse der Wale; Zoologische Jahrbiicher, Abt. fur Anatomie, etc., vol. 32, pt. 4, 1912, pp. 577-651, pls. 33-35), both of whom give references to earlier works. Kiukenthal regards it as most probable that the large number of phalanges in the Cetacea has originated as follows: That the diaphy- ses and epiphyses in an ordinary hand whose fingers had mostly three phalanges have loosened themselves from each other, and have be- come independent and uniform, all of them ossified. This explana- tion cannot possibly be right. It is immediately contradicted by the fact that in cetacean hands with many-jointed fingers there can be found both diaphyses and epiphyses, ossified, in the larger of the phalanges that are present, as Kukenthal himself has observed. If one examines series of adult cetaceans’ hands or of embryo hands, it is quite impossible to detect anything that could point in this direction. It certainly should be possible to find, somewhere or other, transition forms which would show indication that the phalanges were of unlike origin, some of them diaphyses, others epiphyses ; but of this there is not the slightest evidence. Neither is it probable that the forerunners of the whales among terrestrial animals, had, even when young, epiphyses at both ends of all the phalanges, as would be needed in order to explain even tolerably the large number of joints in the -Cetacea. It is true that in the Cetacea there have arisen super- numerary ossified epiphyses, more epiphyses than in their ancestors. But let it be noted that this has only happened in those Cetacea that already had acquired many-jointed fingers. (The objection to the “epiphysis-hypothesis ”’ that it could at most explain the presence of only I2 joints in the fingers, including the metacarpal, and that it therefore cannot hold good where the number of joints is more than 12, is met by Kitkenthal with the admission that in such instances the number of joints is actually increased out beyond the finger tips, bcs, 1803, p. 311.) Another explanation which is more probable Ktkenthal himself sets forth but regards as less happy: ‘“‘ Wurde man die Entwicke- lungsgeschichte allein zur Losung der Frage heranziehen, so wurde sich der Schluss ergeben, dass ausser den vier typischen Finger- 50 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.: 72 elementen sich immer neue anlegen, indem sie sich, in distaler Richtung aufeinander folgend, in dem sich immer weiter vorschiebenden em- bryonalen Bindegewebe entwickeln, so dass die letzte Phalanx die jungste ist” (J. c., 1893, p. 311). Ktikenthal finds a reason to reject this opinion in the fact that Leboucq and he have occasionally found something on the outermost tip of one of the digits of a long-fingered porpoise hand which might be interpreted as the weakest remnant of a nail. Should it prove that remnants of a nail are found on the extreme tip of the finger, says Kukenthal, this “ hypothesis ” con- cerning the origin of the many phalanges cannot be correct, “ denn dann entspricht die Spitze der Walflosse und damit die Spitze von deren Fingern auch der Spitze der Finger der typischen Vorder- extremitat ” (1. c., 1893, p. 312). This objection cannot hold; there is certainly nothing to prevent that the atrophied remnant of a nail should constantly retain its position on the finger tip as this pushes outward further and further, whatever the method by which the finger is elongated. °(P. 5.)

The opinion that the increase in the number of teeth in the Cetacea above the typical eutherian number was perhaps initiated by the intercalation of milk teeth in the permanent set was expressed in 1882 (Vidensk. Medd. for 1882, pp. 31 and 40) at a time when no trace of tooth succession had yet been detected in whales. The same opinion was maintained by Max Weber (Urspr. der Cetaceen, 1886, pp. 195 and 199), but he abandoned it (Die Saugethiere, 1904, p. 567) after Kukenthal had demonstrated indications of the tooth succession. Ktikenthal had found traces of germs of both forerunners and suc- cessors to the teeth which stand in the Cetacea as the permanent set (but which he considered as milk teeth). Perhaps the idea is wrong ; but there is nothing in that which has thus far been discovered which no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE sul makes its abandonment necessary, inasmuch as only a part of the milk dentition, only four cheekteeth, were ever supposed to be inter- calated in the permanent set (it was expressly said that an increase in the number of cheekteeth by other means, by division or by the formation of new elements, was necessary as an explanation when the number exceeded 11 in each jaw) ; and the milk dentition could perhaps be made whole again after having given up some of its contents. In any event it is impossible to trace in detail the destiny of the tooth-germs through their erratic course during atrophy ; there are many possibilities. In spite of all investigations during recent years into the develop- ment of cetacean dentition both embryologically and phylogenetically, no certain conception has been reached. Only this is certain, that the cetacean dentition is derived from the typical carnivore’s, that the teeth are increased in number while their size is decreased and their form made more simple, and that the tooth succession has essentially ceased, although in embryos there can still be detected traces of several sets of teeth, as in many other mammals, faint mementos of their forefathers among the reptiles. But of how the changes have in detail come about we can only partly guess. Abel is the author who has most recently reviewed the present question. He believes that he can more nearly show how the high number of teeth has arisen in the Cetacea; in the whalebone whales he thinks it came about in one way, and in the toothed whales, or at least in the Physeterine series, in another. But his arguments are not irrefutable. As regards the whalebone whales Abel starts from Kukenthal’s ' investigations. As has long been known from observations by Geoffroy Saint-Hillaire and especially by Eschricht, there is found in embryos of all recent whalebone whales, hidden in each jaw, a long row of small atrophied teeth with conical or knob-shaped crowns, which are resorbed without ever erupting. Frequently some of these small teeth are seen to be mutually united; most often it is two that come together but in rare instances as many. as four may unite. A part of his observations on the embryonic teeth of Balenoptera musculus, the species which he has had especially good opportunity to investigate, Kiikenthal summarizes in the following words: “ Die Zahl der Zahne im Oberkiefer des letzteren Embryos (that is, the largest of those examined) ist 53; sie liegen sammtlich in gleich weiten Abstanden von einander. Bei den kleineren Embryonen betragt die Zahl der Oberkieferzahne, wenn wir die mit zwei resp. 4 52 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 drei Hockern versehenen Zahne als je einen Zahn rechnen, etwas weniger, und zwar haben alsdann die kleinsten Embryonen die geringste Zahnzahl. Zahlen wir jedoch in jedem Oberkiefer die einzelnen Hocker, so erhalten wir gleichzeitig fur jeden Kiefer die Zahl 53, dieselbe Zahl, welche wir auch bei dem grossten untersuchten Embryo, der keine Doppelzahne besass, aufgefunden haben. Ich habe aus dieser Thatsache bereits den Schluss gezogen, dass sich im Laufe der individuellen Entwickelung der Bartenwale die Zahne theilen, und dass somit aus den verhaltnismassig wenigen, aber mehr- hockerigen Zahnen der jiingsten Stadien viele, aber einspitzige Zahne werden. Aus den ursprtinglichen Backzahnen entwickelte sich also durch Theilung derselben ein anscheinend homodontes Gebiss. (Unters. an Walthieren ; Denkschr. med. naturw. Ges. Jena, 1893, p. 431). On this Abel builds further. He considers that Patriocetus (see pp. 70-72), a Tertiary whale with rather well- developed dentition, with unicuspid incisors and canines, and with serrate margins to the cheekteeth, is an ancestral form of the true whalebone whales—their immediate precursor. In passing to the whalebone whales its teeth would be split up and the marginal cusps would be transformed into independent teeth: ‘ Wie wir gesehen haben, besteht das Gebiss von Patriocetus ehrlichi aus sieben zwei- wurzligen und siebenspitzigen Backenzaihnen, von denen die drei hinteren als Molaren und die vier vorderen als Praemolaren zu deuten sind. Daran schliessen sich-vorne ein einspitziger Eckzahn und die drei einspitzigen Schneidezahne an. Im ganzen stehen also I1 Zahne in jedem Kiefer.—Wenn wir die Spitzen der Zahne susammen- zahlen, so dass wir nicht nur die Kronenspitzen der vier vorderen Zahne, sondern auch die sieben Zacken der sieben zweiwurzligen Backenzahne als Einzelspitzen rechnen, so ergibt sich eine Gesamt- summe von 53 Spitzen, also genau derselben Zahl, die wir bei dem in Einzelzahne aufgelosten Gebiss des Finwalembryos wiederfinden.— Nach diesem Befunde kann es keinem Zweifel mehr unterliegen, dass das Patriocetus-Gebiss mit elf Zahnindividuen und zusammen 53 Schmelzspitzen den Ausgangspunkt des Bartenwalgebisses dar- stellt und dass die Entstehung des letzteren in der Weise erfolgt, dass die elf Zahne sich im Verlaufe der ontogenetischen Entwick- lung in 53 Teile spalten, so dass also schliesslich aus einem sieben- spitzigen Backzahn sieben einzelne Spitzen durch Teilung und fort- schreitenden Zerfall hervorgehen. (Die Vorfahren der Bartenwale ; Denkschr. Akad. Wissensch. Wien, mathem. naturw. K1., Bd. 90, 1914, pp. 186-187)—Several objections must be raised to Abel’s presentation of the subject. No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 53 Everyone who has had to do with counting the teeth of cetaceans knows how variable the numbers may be. It is almost a miracle that Kukenthal should have been able to find five or six embryos, or perhaps more, of Balenoptera musculus, each of which had 53 teeth or tooth cusps in the upper jaw (see Kutkenthal’s more special account in Jenaische Zeitschrift fiir Naturwissenschaft, vol. 26, 1892, p. 481, together with his paper of 1893, /. c.; in three other jaws the numbers were less, a circumstance said to be accounted for by the fact that some of the teeth had been resorbed). But even if it should prove that B. musculus always had 53 teeth in each jaw of the embryo this fact would be without bearing on the question of the original denti- tion in the whalebone whales. It will occur to nobody to regard B. musculus as one of the most primitive species of the genus; on the contrary it is one of the highest, being one of the largest and most elongated. Other species are found in the genus that stand on a lower: level; this holds good especially of B. rostrata, and in this species Eschricht has found the number of teeth in two embryos to be respectively = + and 2 (Unders. over Hvaldyrene, pt. 3, 1845, pp. 314 and 316-317). In two embryos of the same species Ktiken- thal found 41 in the lower jaw (Jen. Zeitschr., 1892, pp. 485-486). In two embryos of one of the highest species of the genus, B. gigas (sibbaldii) Kukenthal found 50 in the upper jaw (J. c., p. 486). In several embryos of Megaptera boops Eschricht has found from 46 to 51 teeth in each side of the upper jaw, and in the lower jaw rather fewer, the least number 42 (I. c., pp. 311 and 316). Abel says, it is true: ‘Bei jenen Bartenwalen, deren Kiefer eine geringere Zahl _ als 53 Zahnindividuen aufweisen, handelt es sich entweder um fruhere Embryonalstadien, wie bei dem von C. Julin beschriebenen Embryo von Balenoptera rostrata von etwa 48 cm. Lange (41 Zahne), oder um Reduktionserscheinungen ” (J. c., p. 188) ; but this assumption is entirely inadmissible. Abel himself probably had an inkling of it; he adds: “In dieser Frage miissten noch eingehendere Untersuch- ungen auf breiterer Grundlage angestellt werden, um unsere bis- herigen Kenntnisse in dieser Richtung zu erweitern.” Neither can all of what Abel says about the number of teeth or cusps in Patriocetus stand before a closer examination. It is not certain that Patriocetus had 11 teeth in each jaw; none of the skulls that have been found has entire jaws, the anterior part is lacking in them all. The number 11 is therefore only a guess, and scarcely very likely ; judging from the rest of the cranial characters one would 54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 expect a departure from the typical dentition—more teeth. Of the cheekteeth there are only known a few that are tolerably complete ; that every one of them had seven marginal cusps is mere conjecture and not probable; in other cetacea with serrate teeth, both Zeuglo- donts and Squalodonts, the number of cusps varies strongly; no cetacean is known in which the same number of cusps is found on all the cheekteeth. Some dissociated teeth that probably are correctly referred to Patriocetus (Squalodon ehrlichiu), figured by Suess (Neue Reste von Squalodon aus Linz; Jahrb. d. k. k. geol. Reich- sanstalt, vol. 18, 1868, pp. 287-290, pl. 10, figs. 1-3) and reproduced by Brandt (Unters. foss. u. subfoss. Cetaceen Europa’s ; Mém. Acad. Imp. Sci. St. Pétersbourg, ser. 7, vol. 20;° No. 1, 1873, plieaueeneae T1-13), also show other numbers, one of them 9, another 10. More- over it is doubtful whether Patriocetus can be regarded as an ancestor of the whalebone whales; it is not precluded that with more exact acquaintance it will show itself to stand on a higher level, nearer to the typical Squalodonts, closely connected with Agorophius (see note, p. 72). In short the whole calculation about the 53 teeth in the whalebone whales and the 53-tooth cusps in Patriocetus rests on the weakest foundation. It is also a question whether Kitkenthal and Abel are on the whole right in their conception of the many small teeth of the whalebone whales as having originated by the division of fewer, larger, serrate teeth. There is indeed scarcely any doubt that a division of the tooth germ might be able to take place at an early stage of a tooth’s develop- ment; but that a tooth which had already acquired serrate margins should be able to divide is not probable; in the case of the whalebone whales at any rate there is nothing convincing in this respect—quite the contrary; and other cases are not known. The “ double-teeth ” of the embryo whalebone whales are the ones that are conceived to be serrate teeth in course of division; but they could be better ex- plained in another manner. Their position in the toothrow is quite erratic—sometimes far to the front, sometimes in the middle or far back. The number of cusps is most often two, only in rare instances as many as four. The cusps have the appearance of being of equal rank, none can be called the chief cusp. In short, the cusps in the double teeth appear to be small, atrophied, unicuspid teeth which have quite casually come near each other and grown together, some- thing which might be able to take place with special ease in the youngest stages of the embryo when the tooth germs are crowded together in relatively short jaws. That double teeth were produced no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 55 by the fusion of single teeth was already supposed by Eschricht (1. c., p. 312). Should it be the case that there has taken place in the whalebone whales a splitting up of serrate teeth, the correspond- ing ancestral forms must probably have had teeth in which the cusps on the fore aud hind margins of the crown had great independence and a size very nearly the same as in the principal cusp. In that event it would not be easy to regard Patriocetus as an ancestor ; since in it the cusps on the fore and hind margins particularly are weak in proportion to the main cusp, and apparently in course of atrophy. Abel gives the following as his conception of the manner in which the many small teeth of the Odontoceti, or at least of the Physeterids, have arisen: “ Dieser Spezialisationsweg des Gebisses (in the whale- bone whales) ist fundamental von jenem verschieden, den wir in der Phylogenese des Physeteridengebisses finden. Wie ich 1905 gezeigt habe, tritt auf dem Wege zur Entstehung der Squalodontiden zunachst eine starke Vermehrung der mehrwurzeligen, vorn und hinten gezackten Backenzahne ein, so dass sich das primitive Arch- aeocetengebiss durch Vermehrung der Backenzahne im Pramolaren- abschnitt zu dem polyodonten Squalodontidengebiss umformt. Aus den Squalodontiden sind die Physeteriden hervorgegangen, bei welchen das Gebiss eine Reduktion erfahrt ; dieser Spezialisationsweg fuhrt aber zu einer Vereinfachung der Krone, Verschmelzung der bifiden Wurzeln, Reduktion der Zackenreihen am Vorder- und Hin- terrande der Kronen zu einer krenelierten Leiste und endlich zum ganzlichen Verlust der Schmelzkappen ” (1. c., p. 187). Here Abel is no doubt right in the main. It can only be objected that it cannot exactly be said that Abel in his more special account (Die phylo- _ genetische Entwicklung des Cetaceengebisses und die systematische Stellung der Physeteriden ; Verhandl. Deutsch. Zool. Gesellsch., 1905, pp. 84-96, and Les Odontocétes du Boldérien; Mém. Mus. Roy. d’Hist. Nat. de Belgique, vol. 3, 1905) has demonstrated that it is precisely in the premolar region that the number of teeth has been increased in the Squalodonts; neither is it probable that the Physe- terids originated directly from the Squalodonts. They appear to have branched off at a higher level; probably they had their root in common with the Delphinids. There is no reason at the present stage for believing that the increase in the number of teeth beyond the typical formula should have had a different origin in the Mystacoceti and Odontoceti. In view of the great resemblances that are everywhere found between the two groups it is not likely that in this respect there would be a 50 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 difference. The method by which the increase has come about in the Odontoceti no doubt holds good for the Mystacoceti as well ; the most primitive forms of probably both groups had serrate teeth in aug- mented numbers. *(P. 10.) It has become usual to believe that the precursors of the cetaceans were armored mammals with well-developed osseous dermal plates. Heated support for this idea is brought forward by Kiiken- thal (especially in the section “ Ueber Rudimente eines Hautpanzers bei Zahnwalen,” in Vergl. -anat. u. entwickelungsgesch. Unters. an Walthieren, part 2, Denkschr. d. med. naturw. Ges. zu Jena, vol. 3, pt. 2, pp. 251-258, pl. 16) and by Abel (especially in the section “T?armure dermique,”’ in Les Dauphins Longirostres du Boldérien, Mém. Mus. Roy. d’Hist. Nat. de Belgique, vol. 1, 1901, pp. 17-32, with illustrations). Kitkenthal has investigated recent cetaceans ; Abel more particularly the extinct forms. (In Abel is found refer- ence to previous literature on the subject.) Kiukenthal imagines that the Cetacea originated from armored land-mammals with armor sug- gesting that of the Dasypodids, and that as sea dwellers they have jost the armor more or less completely; Abel thinks, in agreement with Dollo, that the armature did not occur in the terrestrial pre- cursors of the cetaceans, but that it arose in the first whales as part of their adaptation to aquatic life along the coast, and that afterwards it was lost in the more strictly marine members of the group. What we have to build upon is the following : Together with the first lot of Zeuglodon bones found in Alabama came a few pieces of limestone containing some plate-like, very irregular bones of various sizes. Accounts of. these bones are due especially to Joh. Miller (Ueber die fossilen Reste der Zeuglodonten von Nordamerica, 1849, p. 34, pl. 27, fig. 7), Carus (Das Kopfskelet des Zeuglodon hydrarchus; Nova Acta Acad. Caes. Leop. Carol., vol. 22, pt. 2, 1850, pp. 382-383, pl. 39A, fig. 5), Dames und Jaekel (section Ueber den Hautpanzer der Zeuglodonten, in Dames, Ueber Zeuglodonten aus Aegypten, Palaeontol. Abhandl., herausgeg. v. Dames u. Kayser, vol. 5, pt. 5, 1894, pp. 219-221, with illustration) and Abel (1go1, l. c., pp. 24-27). From the beginning the possibility has been thought of that the plates were dermal bones of Zeuglodon. They have, however, most often been regarded as doubtful; perhaps they were bones from the carapace of a sea turtle like Psephophorus or something of the sort; usually no one has dared to say anything positive. Abel was the first to consider it as proved that they were dermal bones of Zeuglodon; of one of the specimens in question he No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 57 thinks that it can be nothing else than a piece of armor from the fore angle of a dorsal fin, because the plates are bent toward each other like a roof, ina manner and form that is not possible on any part of a turtle’s carapace. As a not unessential ground for believing in the occurrence of armor in Zeuglodon he reckons the occurrence in the recent Delphinids Neomeris and Phocena of structures which Ktiken- thal explains as remnants of armor. At Radoboj in Croatia some remains have been found of a small dolphin-like cetacean, Delphinopsis freyerii, established and de- scribed by Joh. Miller (Bericht titber ein neu entdecktes Cetaceum aus Radoboy, Delphinopsis Freyerii; Sitzungsber. k. Akad. Wis- sensch. Wien, math. naturwiss. Cl., vol. 10, 1853, pp. 1-6 of separate), and again fully discussed and figured by H. v. Meyer (Delphinopsis Freyerii Mull. aus dem Tertiar-Gebilde von Radoboj in Croatien; Palaeontographica, vol. 11, 1863, pp. 226-231, pl. 34) whose illustra- tion is reproduced by Abel (J. c.), who also has personally examined the remains. It was only imperfect remains that were found, not much more than pieces of a flipper lying in a slab of stone; around the bones of the hand lie numerous small disk-shaped bodies a milli- meter or less in diameter, the underside of which is covered with minute projecting granules arranged in parallel lines. Joh. Miiller seems to have left undecided the question whether these bodies were of organic or inorganic origin, although he leaned mostly to the opinion that they were osseous scales from the skin. But H. v. Meyer maintained that they were inorganic. His reason for this opinion was especially that scattered among them there lie bodies of entirely similar appearance only without markings, and these bodies are undoubtedly inorganic. Abel on the contrary is convinced that the small, striated disks are dermal ossicles. In Neomeris, which lacks or as good as lacks the dorsal fin, the skin -of the back in the place where the fin is found in its relatives, and also somewhat further forward and backward, is divided into small, rather regularly placed plates, each bearing a small elevation. Similar small knobs are found, though not always, in the nearly related genus Phocena, along the anterior surface of the dorsal fin and sometimes also scattered in other regions. Kiikenthal, who has closely examined these structures, thinks that they are a kind of scale, although they have in their intimate formation only toa slight degree the characters that are found in scales. The explanation given is that they are 58 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL V2 scales which are in process of atrophy—on the way to disappearing. A concurrent reason to regard them as scales is that traces of a scaly covering are found in some extinct whales, Zeuglodon and _ Delphinopsis. But to Kukenthal’s and Abel’s conception there is something to oppose. It has been shown that the Hyzenodonts, the most primitive car- nivores, are the precursors of the Cetacea among terrestrial mammals. Remains of Hyznodonts are found in great numbers in many locali- ties; but there has never been discovered the slightest indication that any Hyzenodont or any other carnivore has been armored. Remains of Zeuglodonts are found in various parts of the world, but nowhere except in the case of the specimens from Alabama have dermal ossicles been demonstrated in connection with the skeletons. If there had been a dermal armature it certainly would have been found some- where or other. Besides, it cannot be said to be proved that the plates from Alabama are not those of some kind of turtle. Anyone who has seen the roof-shaped keel on a Psephophorus carapace, and has seen the fragments of the carapace mixed up together, will not allow himself to be persuaded by Abel’s word in this connection. Finally it is improbable that Zeuglodon had a dorsal fin, since this fin may be absent (probably not-developed rather than lost) in diverse recent cetaceans, both Balzenids and Delphinids. The minute plates in Delphinopsis are altogether too uncertain to give any evidence. Their characters are, besides, so far from recall- ing what is otherwise known of dermal bones that one is tempted rather to regard as an error their determination as such structures. The small callosities in the skin of Neomeris and Phocena are scarcely the remains of a dermal armature, they are rather entirely new structures. It is too suspicious that nothing of the sort should be present in lower Cetacea, but that it should be in exactly some of the very highest that it is found. The structure of the callosities, moreover, gives no real support to the idea that they are scales. Altogether there is no proof that the Cetacea or their ancestors among the mammals ever have had dermal armature. *(P. 10.) For comparison a few of the most important and most independent synopses of the groups of Cetacea are here given. A fundamental work in the direction of throwing light on the mutual relationships of the Cetacea is due to Flower, who, however, took into consideration the recent forms only. In 1866 (69), in his No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 59 paper on Jnia and Pontoporia (Trans. Zool. Soc. London, vol. 6, p- 115), he gave the following synopsis: Cetacea. I. Mystacoceti or Balenoidea. Balenide. Baleninz: Balena, Eubalzna. Balenopteride. Megapterine: Megaptera. Baleenopterine: Physalus, Sibbaldius, Balenoptera. II. Odontoceti or Delphinoidea. Physeteride.

Beluginee: Monodon, Beluga (=Delphinapterus). Delphinine ?: Phoczna, Neomeris, Grampus, Orca, Pseu- dorca, Lagenorhynchus, Delphinus, Delphinapterus (=Tursio), Globicephalus. His conception of the relations between the genera in the family Delphinide Flower developed more fully in 1883 (Proc. Zool. Soc. London). His arrangement there was as follows: A, a. Monodon, Delphinapterus (Beluga). b. a. Phoczna, Neomeris. 8. Cephalorhynchus, Orcella, Orca, Pseudorca, Globiceps, Grampus, Feresia, Lagenorhynchus. By a. a. Delphinus. 8B. Tursiops, Clymenia, Steno. b. Sotalia. Flower followed essentially the same arrangement as that of 1866 and ’83, but with greater clearness as to the genera, in 1891, in “ An Introduction to the Study of Mammals Living and Extinct ” which 60 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 be published in association with Lydekker. The arrangement is as follows: Cetacea. Mystacoceti, Balenoidea. Balenide: Balena, Neobalena, Rhachianectes, Megaptera, Balenoptera. Extinct Genera: Cetotherium, Herpetocetus. Archeoceti. Zeuglodontide: Zeuglodon. Odontoceti, Delphinoidea. Physeteride. Physeterinz : Physeter, Cogia. Extinct: Physeterula, Eucetus, Physetodon, Scaldicetus, Physodon, Hoplocetus. Ziphiine: Hyperoodon, Ziphius, Mesoplodon, Berardius. Extinct: Choneziphius. Squalodontide: Squalodon. Platanistide: Platanista, Inia, Pontoporia. Extinct: Palzopon- toporia (Pontistes), Champsodelphis, Schizodelphis, Pris- codelphinus, Lophocetus, Ixacanthus, Rhabdosteus, Agabelus. . Delphinide. Group A. Monodon, Delphinapterus, Phoceena, Neomeris, Cephalorhynchus, Orcella, Orca, Pseudorca, Globicephalus, Grampus, Feresia, Lageno- rhynchus. Group B. Delphinus, Tursiops, Prodelphinus, Steno, Sotalia. Max Weber (Die Saugethiere, 1904) agrees closely with the con- ception of Flower and Lydekker. One of the greatest differences is that a special family, Rhachianectid@ is established for Rhachionectes and also a family Delphinapteride for Delphinapterus and Monodon. Abel has made special researches on the fossil Cetacea, and he has tried to determine their positions in relation to the recent forms. Besides what he has said on the subject in his special monographs, he has more or less completely set forth his ideas in the papers: Die . Stammesgeschichte der Meeressaugetiere; Meereskunde, Sammlung volksttmlicher Vortrage, 1907; Grundziige der Palaentologie der Wirbeltiere, 1912; and Die vorzeitlichen Saugetiere, 1914. He has not given any general synopsis except in the following genealogical tree, published in his work Die Vorfahren der Bartenwale, 1914 no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 61 (Denkschr. k.

(To the Acrodelphide are referred, among the living genera, Del- phinapterus and Monodon, Inia and Pontoporia.) True’s paper On the Classification of the Cetacea (Proc. Amer. Philos. Soc., Philadelphia, vol. 47, 1908, pp. 384-391) is mostly an account of the opinions which Abel had expressed in 1905, with some objections and some assent. To cetaceans both recent and fossil have been given various generic names in addition to those which appear in the present article. These “names are partly well known as synonyms of others; but partly the corresponding animals are so slightly known that no certain opinion can be had about them. References to all the names theretofore used for cetaceans are found in Trouessart, Catalogus Mammalium tam viventium quam fossilium, 1897-99, with supplement, 1904-5, and in Palmer, Index Generum Mammalium, 1904; many names are also to be found in Beddard, A Book of Whales, 1900 ; detailed references to the North American fossil genera are due to Hay, Bibliogr. and Catal. of the fossil Vertebrata of North America, Bull. U. S. Geol. 62 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Surv., No. 179, 1902. Incorrectly formed names which cannot be accepted as finally settled are, in the present treatise, marked with “ ns * (P. 13.). The backbones of the Egyptian “ Zeuglodon”’ osirts with its short vertebre (especially Stromer, Beitr. Palaontol. u. Geol. Oesterreich-Ungarns, etc., vol. 21, 1908, pl. 4, fig. 1), and those of the American Z. cetoides with its long vertebre (especially Gidley, Proc. U. S. Nat: Mus., vol. 44, 1913, p. 81) differ to. sich aydegres that according to ordinary standards the placing of these animals in the same genus, as has hitherto been done, is certainly out of the question. Z. cetoides is the type of the genus Zeuglodon. By acci- dent no special name has been proposed that can with full right be used for the genus to which “ Zeuglodon”’ osiris belongs. But the name Prozeuglodon seems to have become vacant and may therefore with some propriety be used. It was proposed by Andrews (espe- cially Tert. Vertebr. of the Faytm, Egypt, 1906) for a lot of Eocene cetacean remains from Egypt which he united under the name P.atrox. But according to Stromer, the type of the species, a skull, and some of the other remains belong to the previously described Zeuglodon isis, which is probably correctly called Zeuglodon, while still others are referable to “ Z.” osiris. In a way therefore “ Z.” osiris has also been called Prozgeuglodon. Possibly the name Doryo- don (“ Dorudon”) might be used for the genus in question with short vertebre, or, if there are several genera with short vertebre, for one of them (see, among others, Leidy, Journ. Acad. Nat. Sci. _ Philadelphia, ser. 2, vol. 7, 1869, pp. 428, 431, and Lucas, Proc. U. S. Nat. Mus., vol. 23, 1900, p. 331). But Doryodon is still not suffi- ciently known, not even after True (Bull. Mus. Comp. Zool., vol. 52, 1908, pp. 65-78, pls. 1-3) has examined the fragments on which Gibbes founded the genus; the remains in question are altogether too incomplete. For the American “ Zeuglodon brachyspondylus minor” Joh. Miller and Stromer, also with short vertebrz, which True compares with Doryodon and finds different, True (J. c.) pro- poses to erect a new genus, Zygorhiza; but the relationship between it and “ Zeuglodon”’ osiris is not at all clear. “(P. 15.) The pelvis and femur of Zeuglodon cetoides are described and figured by Lucas (Proc. U. S. Nat. Mus., vol. 23, 1900, pp. 327-331, pls. 5-7). Both right and left innominates were found associated with a backbone lying in the position relative to the vertebrze in which one would expect to find them. In spite of this circumstance Abel explained the bones in question as the coracoid of no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 63 a gigantic bird which he called “ Alabamornis”’ gigantea (Ueber den als Beckengtrtel von Zeuglodon beschriebenen Schultergurtel eines Vogels aus dem Eocan von Alabama, Centralblatt fur Mineralogie, Geologie und Palaontologie, 1906, pp. 450-458, with illustrations). Stromer (Beitr. z. Palaont. u. Geol. Oesterreich-Ungarns, etc., vol. 21, 1908, p. 146) has expressed doubts as to the correctness of Abel’s interpretation, and Gidley (Proc. U. S. Nat. Mus., vol. 44, 1913, pp. 649-654, with illustrations) who has re-examined the specimens, has entirely thrown it over. It can hardly be doubted that Lucas and Gidley are correct. *(P. 15.)

That which has been found is not much else than a lot of loose teeth which show strong similarity to Zeuglodon, but it is impossible to get any certain idea of the exact generic relationships. Hall (Proc. Roy. Soc. Victoria, n. s., vol. 23, pt. 2, I91I, p. 262) refers it to the Squalodontidae but gives no reasons. Microzeuglodon was established by Stromer (Beitr. Palaont. u. Geol. Oesterreich-Ungarns, vol. 15, 1903, p. 89) and accepted by Abel (Odontocétes du Boldérien, 1905, p. 35). The basis of the genus 1s Lydekker’s Zeuglodon caucasicus (Proc. Zool. Soc. London, 1892, pp. 559-561, pl. 36), based on a few remains, not certainly be- longing together, found in Tertiary strata in the Caucasus: a small piece of a lower jaw with four cheekteeth, only two of which are tolerably complete, a humerus and a caudal vertebra. The teeth are serrate on both fore and hind margins of the crown. Abel referred No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 65 it at first to the Squalodonts, later he put it in a separate family. It plays an important part in Abel’s studies of cetacean descent, whether rightly or not time will perhaps tell ; meanwhile the genus is altogether too slightly known for anything positive to be built on it. Eocetus described by Fraas (first called Mesocetus Fraas, not of Van Beneden, not of Moreno) is thought to be a connecting link between Protocetus and Zeuglodon, with long vertebrae. The remains are still too uncertain for judgment to be passed. *(P. 19.) Kikenthal (Vergl. -anat., etc., Unters. an Walthieren ; Denkschr. medic. -naturw. Ges. Jena, vol. 3, pt. 2, 1893, p. 291) thinks that the bone in the hand of Balena mysticetus, which is ordinarily regarded as a remnant of the first finger, a first metacarpal, is not that, but a finger before the first finger, a prepollex, in spite of the fact that the same bone in Balena australis (as can also be seen in two skeletons in Copenhagen) may bear two well-developed phalanges, something that is not elsewhere seen in any “ prepollex.’ As to the longest finger, which is usually reckoned as the third, he believes that it is not the third but the second, and that the third is absent. The reason for this remarkable interpretation is probably a desire to find agreement with Balenoptera, in which he thinks he has proved that the third finger is the one which is absent, and not the first as is gen- erally supposed. If the first finger were present in Balena in a more or less atrophied condition, it would be reasonable to suppose that it was this finger which is absent in the nearly related Balenoptera, which has only four digits; but that belief Kukenthal will not allow. Occasionally he has found in Balenoptera musculus something re- sembling a few atrophied phalanges lying loose in the palm between ‘the fingers that are usually called the third and fourth. These structures Kiikenthal regards as remnants of the third finger and thus to be proof that it is the third finger which is absent in the tetradactylous hand. Protest against Kukenthal’s interpretation has already been made by Braun and Kunze (see Kunze, Zool. Jahrb., Abth. f. Anat., etc., vol. 32, 1912, pp. 639-641). There can be no doubt that there is here a case of malformation, a supernumerary digit, a kind of doubling of one of the fingers. Tendencies in this direction are indeed not rare in cetaceans, which on the whole show great indifference as to details in the structure of their abnormal hand. “(P. 21.) Onthe Balenidz see especially (Of the numerous works that deal with cetaceans there are many others that might have a claim to be mentioned.

Besides Plesiocetus and Cetotherium many other genera of fossil Balenids have been described, especially in papers by Van Beneden, Brandt and Cope, but the bases for most of them are scanty. H. Winge (Om Plesiocetus og Sqvalodon fra Danmark, Vidensk, Medd. Natur- hist. Foren. 1909) has attempted to estimate the value of a number of the genera in question: Aulocetus, Mesoteras, Cetotheriopsis, Megap- teropsis, “ Burtinopsis,” Herpetocetus, Eucetotherium, Plesiocetopsis, Cetotheriophanes, Cetotheriomorphus, Idiocetus, Heterocetus, Amphi- cetus, Mesocetus, Isocetus, Pachycetus, Siphonocetus, Ulias, Tre- 7O SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 tulias, Metopocetus, Cephalotropis, Rhegnopsis. It is apparent that as regards most of them there is scarcely any reason for separation from Plesiocetus or Cetotherium or from recent genera, and that the few which appear to be more peculiar are so slightly known that they can scarcely be classified. True (The Genera of Fossil Whalebone Whales allied to Balenoptera, Smithsonian Misc. Coll., vol. 59, No. 6, 1912, pp. 1-8) who later went over the subject came in all essentials to the same conclusion. Agriocetus is most likely a whalebone whale, but it is too slightly known to be classified. It was described by Abel (1914, l. c., pp. 188- 194, pls. 4, 5, 7) from a very imperfect and indistinct skull from Tertiary strata at Linz, referred to Squalodon by earlier authors. Abel regards it as a near relative of Patriocetus, a step nearer to the true whalebone whales. Only better discoveries will show whether he is right or not. Perhaps. Patriocetus belongs to the family Balenid@ as it is under- stood in the present work, but it is not sufficiently known to be definitely placed. It was described by Abel (1914, l. c.) who has given a full account of the history of the remnants in question. The basis of the genus was partly some rather imperfect fragments which previously had most often been referred to under the name Squalodon ehrlichii, partly a quite well-preserved skull found later, all from Tertiary strata at Linz. If Abel’s interpretations and conjectures are right he is no doubt correct in regarding Patriocetus as a precursor of the true whalebone whales. Abel refers it to the Archzoceti, or at least leaves the question undecided whether it actually belongs to this group or to the Mystacoceti (Die vorzeitl. Sauget., 1914, p. 88) ; most probably it should be regarded as a whalebone whale, a Balzenid with the dentition still functional. But there is reason for doubt about certain details in Abel’s account. Patriocetus has in the skull a remarkably strong resemblance to Agorophius, a resemblance that was seen by Brandt (1873, l. ¢., p. 324) although the remains then at hand were rather insignificant ; and Agorophius belongs incontestably to the series of toothed whales as a near relative of Squalodon. The peculiarity which places Agor- ophius among the Odontoceti in opposition to the Mystacoceti is that the maxillary bone pushes itself posteriorly as a thin limina over the supraorbital process of the frontal, but does not stop in front of it, or push itself in under it, or content itself with also covering it with a narrow margin anteriorly. According to the great resemblances which are found otherwise between the skulls of Agorophius and No. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 71 Patriocetus one would expect that the two genera would resemble each other in this particular also; but according to Abel’s representa- tion Patriocetus is here like the whalebone whales. According to the photographic illustrations which accompany Abel’s paper it is scarcely possible to see whether his exposition of the conditions is right or not; the skull is too weathered and obscure. There is, how- ever, a detail in his description of the boundary between the maxillary and frontal, which probably must be wrong or at least must awaken doubt. He says of the maxillary that it, at its postero-internal ex- tremity, does not extend nearly so far backward as the nasal process of the intermaxillary, which, on the contrary, like that of other whales, extends up, far backward, alongside the outer margin of the nasal and beyond. But there is elsewhere no cetacean, either among the Archeoceti, Mystacoceti, or Odontoceti, in which the maxillary does not reach postero-internally as far back as the intermaxillary or even further, pushing itself up over the frontal. This is an inheritance from ancestors among the carnivores or from yet more distant fore- runners. Abel says, it is true (/. c., p. 162) that Patriocetus in this regard resembles /thachionectes, one of the recent whalebone whales ; but this is an error. In one of the figures of the skull of Rhachi- onectes published by Andrews (1914, /. c., pl. 25) it can be clearly seen that a long process from the maxillary extends along the outer side of the intermaxillary to its hindmost end; and it is so described by Andrews (p. 261). In the second of Andrews’ figures the process is not visible; it is obviously broken off, as it is in the figures pub- lished by Van Beneden (Bull. Acad. Roy. Sci. etc., de Belgique, Seer volnas: Nore, Pebriary, 1877, pl) and» True «(1904; 1.¢., pl. 47, fig. 1), both of which represent the same skull (it is True’s figure to which Abel refers). A similar injury no doubt must have been suffered by the skull of Patriocetus; and if this process can be broken away without leaving visible traces behind it the same might be possible in the case of a thin plate-like process that originally covered the supraorbital process of the frontal. How readily some- thing of the kind can take place is shown by the type of Agorophius (figured by Leidy, under the name Squalodon pygmeus, Journ. Acad. Nat. Sci. Philadelphia, ser. 2, vol. 7, 1869, pl. 29, and by True, ‘Smithsonian Inst. Special Publ., No. 1694, 1907, pl.) : on the right side of the skull large parts of the plate-like outgrowths from the maxillary over the supraorbital process of the frontal are broken away without having left behind any conspicuous traces on the frontal. SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL 72 NI bo In Abel’s treatment of the dentition in Patriocetus there are also various doubtful points. He asserts that the complement of teeth is the one which is typical of the placentalia, ri teeth in each jaw; but it is impossible to see how he has arrived at this conclusion. The best skull in question lacks the anterior part of both upper jaw and mandible, and it is impossible to say how much is lacking, or how many teeth were implanted in the missing parts. Of teeth fixed in the jaws there are known for the most part mere stubs—sometimes noth- ing but roots. Besides these there are some dissociated teeth whose position in the jaws is not certain. All that can be said is that some of the teeth were simply conical with single root, and that most of the cheekteeth had serrate crown and double roots. Altogether there is not enough known to elucidate all the details of the dentition. It is not probable that Abel should be right in his belief that the teeth were present in the typical number. Such a cetacean as Patriocetus, the skull of which was already highly developed in the direction of the most advanced whales, scarcely could have had about the same dentition as the Zeuglodonts. It is much more likely that the number of teeth was increased above the typical as it is or has been in all the Mystacoceti and Odontoceti which are known in this respect. In order to believe in Abel’s representation of the facts we must see more incontestable finds. (See also note 7, pp. 52-54.) *(P. 23.) The asymmetry in the skull of the toothed cetaceans has often been written about. Special treatises on the subject are due to Pouchet (De l’asymétrie de la face chez les Cétodontes ; Nouv. Arch. du Mus. d’Hist. Nat. Paris, 1886, pp. 1-16 of separate), Abel (Die Ursache der Asymmetrie des Zahnwalschadels ; Sitzungsber. k. Akad. Wissensch. Wien, Math.-naturw. Cl., vol. 111, pt. 1, 1902, pp. 510-526, pl.), Kukenthal (Ueber die Ursache der Asymmetrie des Walschadels; Anat. Anzeiger, vol. 33, 1908, pp. 609-618, with illustrations) and Steinmann (Ueber die Ursache der Asymmetrie der Wale; Anat. Anzeiger, vol. 41, 1912, pp. 45-54, with illustra- tions) ; Pouchet and Abel refer to various earlier papers by other writers. As to the reason for the crookedness Pouchet says: ‘“ Nous en ignorons l’origine.” In 1893 Kuikenthal said very nearly the same: ‘“ Die physiologische Ursache kennt man nicht, vielleicht ist sie in der eigenthiimlichen Art der Locomotion vermittelst der Schwanzflosse zu suchen” (Ver- gleich.-Anat. u. entwickelungsgesch. Untersuch. an Walthieren, pt. 2; Denkschr. med.-naturwiss. Ges. zu Jena, vol. 3, pt. 2, p. 342), a NO. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 73 thought that was not at the time carried further. But in 1908 Kiiken- thal tried to give a more exact explanation. To begin with he thought he could prove that the asymmetry in the bones of the face is found not only in toothed cetacea, but also in the whalebone whales, though only slightly defined. In two skulls of Balenoptera (of B. rostrata and B. musculus) he had found certain of the facial bones just a trifle broader on the right side than on the left. Next he discovered that some embryos of toothed cetaceans, of Platanista, Steno, Glo- biceps, Delphinus, Phocena, Hypercodon, had the caudal fin set awry, not level but in such a position that the left fluke “ etwas schrag nach aufwarts, der rechte schrag nach abwarts gerichtet war” (p. 614). In 12 embryos of Delphinapterus the fin was, on the con- trary, horizontal. All the embryos of whalebone whales examined (of Balenoptera musculus and B. gigas) had the fin oblique in the same manner as the toothed whales. How the fin is in adult cetaceans is said to be not clearly understood; a few observations by other investigators may, however, indicate that the obliquity is present in the adults also. When a whale propels itself forward by means of a sculling movement of the oblique caudal fin it is said to turn at the same time to the left: “ Der Wal durchschneidet also bei derartiger schrager Bewegung der Schwanzflosse das Wasser nicht genau in der Richtung seiner Langsachse, sondern sein Weg verlauft von dieser Geraden etwas schrag nach links zu” (p. 616). And from this is said to result an oblique pressure of the water on the head, and con- sequently the obliquity of the skull, since the bones on the left side are pressed upon more than those of the right side, are made thicker, etc.: “ Der Druck der beim Schwimmen durchschnittenen Wasser- massen wird auf die linke Seite des Vorderkopfes starker wirken als auf die rechte. Dieser Druck pflanzt sich durch die elastischen Weichteile des Vorderkopfes hindurch auf die darunter liegenden Schadelknochen fort. Die Wirkung dieses starkeren Druckes muss sich zunachst in einer Verdickung der entsprechenden Schadel- knochen aussern . .. .” (pp. 616-617). That the bones in the left side of the face are not so wide as those of the right side is said to be connected with the fact that the bones of the left side are the thickest : “Es wird dadurch links eine kleinere Flache als rechts geschaffen, welche den etwas starkeren Druck auszuhalten hat und damit bis zu einem gewissen Grade einen Ausgleich gegentiber der rechten Seite herbeiftihrt ” (p. 617). Abel believes that the reason for the asymmetry of the skull in toothed whales is to be found in the atrophy of the nasal bones, etc., 74 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 and in the shortening of the braincase, but cannot prove that asym- metry would be the necessary result of these causes. Lillie (section The asymmetry of the Odontocete skull, in Observa- tions on the anatomy and general biology of some members of the larger Cetacea; Proc. Zool. Soc. ‘London, 1910, vol. 2; pp. 7e"-yess with figure) shows that the pharynx in Physeter is asymmetrical, divided by the projecting larynx, which is strongly displaced to the left, into a more spacious right and a narrower left section to accom- modate the passage of food. In this circumstance should be found the source of the asymmetry of the face ; why, is not further explained. Steinmann starts from Kukenthal’s assertion about the asymmetry in the candal fin. Kukenthal had said nothing as to the cause of this crookedness, but Steinmann believes he has found it in the supposed fact that whales originated from Ichthyosaurs and other marine reptiles with a vertical fin, and that on its way to the horizontal posi- tion the fin has come to rest obliquely. Kukenthal is doubtless the one who has come nearest to the truth. However, there are numerous objections to be raised against his explanation. It cannot be said with any degree of correctness that the skull in the whalebone whales has an asymmetrical face. A series of skulls is before me, representing Balena, Balenoptera and Megap- tera. Such asymmetry as can perhaps be shown here and there is similar to that which is found in most mammals. I myself have seen many cetacean embryos (in alcohol), representing both whale- bone whales and odontocetes (of the former I have examined in this connection embryos of 3 Balenoptera rostrata, 2 B. musculus, 5 Megaptera boops, of the latter numerous embryos representing the genera Delphinapterus, Monodon, Prodelphinus, Delphinus, Lageno- rhynchus, Globiceps, Phocena, Neomeris; I have been content with examining the tails externally, | have not cross-sectioned them), but I have not been able to convince myself of the presence of oblique- ness in the tail which did not appear to find its explanation in artificial pressure. I have also seen various adult newly dead cetaceans, both whalebone whales and toothed cetacea of different kinds. It is true I did not expressly examine them to observe obliqueness of the tail, but I cannot recall the slightest evidence of its existence. Neither can anything be detected in the numerous photographs of whales that are before me. That obliqueness of the tail can actually be present appears to be proved by Kukenthal’s figure of a cut off tail of Balen- optera, which shows the flukes placed obliquely in relation to the caudal vertebre ; but it must probably be an exception. Even if it no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 75 were true that the caudal fin in cetaceans was usually obliquely set this would probably not hinder whales from swimming forward in a straight line if they so wished. That the obliquity of the tail, if it occurs as represented by Kukenthal, does not in any event necessarily carry with it the asymmetry of the skull is proved by the whalebone whales, whose tail is said to be oblique, but whose skull 1s without asymmetry in spite of Kukenthal’s word to the contrary. And that the asymmetry of the face is not dependent on obliquity of the tail is proved by Delphinapterus, whose tail, also according to Ktkenthal’s interpretation, is not oblique, but whose skull is distinguished by a high degree of asymmetry. Should the water’s pressure work most powerfully on the /eft side of the head it would be difficult, in spite of Kukenthal’s attempt at an explanation, to understand why the bones on the left side of the skull are narrow while those on the right side are broad, or why the nasal passage is pushed over toward the left side, a point that Kukenthal does not try to argue. Of Kuken- thal’s explanations scarcely anything is left except the knowledge that it is the pressure of the water which is responsible for the asymmetry of the skull in the Odontoceti. Why the water presses obliquely is still unknown, but the reason is not likely to be anything else than a habit in the carriage of the head: the head presumably must be held a little obliquely even when the animal is swimming straight forward ; and the pressure must be strongest on the right side. *(P. 24.)

Abel (Odontocétes du Boldérien, 1905, pp. 35-36) established the genus on the basis of Tertiary remains from Acqui which Brandt had called Squalodon gastaldii. In a letter to Abel, however, which Abel printed, Dal Piaz explains that these specimens, which he had had the opportunity to see, must be referred to the earlier described Neosqualodon. Parasqualodon and Metasqualodon are proposed by Hall (1911, l. c.) to include Tertiary Australian species that previously were referred to Squalodon: S. wilkinsont M’Coy and S. harwoodu Sanger. The genera are supposed to be nearly related to Prosqualo- don, but they are known from loose teeth only and their status is still uncertain.

Burmeister is said to have put together parts of two different genera that should bear the names Saurodelphis and no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 79 Pontoplanodes. At present the problem cannot be said to be solved; but there appears to be no good reason to doubt the correctness of Burmeister’s determination. In the present paper his presentation of the subject is followed. A piece of the beak of Saurodelphis with the 8-shaped alveoli is in the Copenhagen museum. Gerrit S. Miller: A new River-Dolphin from China; Smithsonian Misc. Coll., vol. 68, No. 9, 1918, pp. I-12, pls. 1-13. Lipotes. Ischyrorhynchus was based by Ameghino (Caracteres diagnosticos de cincuenta especies nuevas de Mamiferos fosiles argentinos ; Revista Argentina de Historia Natural, vol. 1, 1891, pp. 163-165, with illus- trations) on the anterior part of a lower jaw from the ‘ inferior del Parana.” The branches of the jaw, which are rather * oligoceno heavy, are grown together in a long symphysis menti; the rows of teeth are further apart than in Saurodephis (Saurocetes), with which Ameghino associates the genus, and the roots in cross-section are almost what might be called ovate, not 8-shaped; the crowns are known only imperfectly. It is not possible to decide where the genus belongs. Pontivaga was also based by Ameghino (J. c., pp. 165-166, with illustration) on the anterior part of a lower jaw, from the “ oligoceno superior ’ at Parana. The branches of the jaw are slender and are grown together in a long symphysis. Each of them contains a long row of small teeth, to judge by the alveoli. Ameghino places the genus in the Platanistid@, in contrast with the Saurocetide, whether rightly or not cannot be said. A genus Proinia is established by True (A new genus of fossil ’Cetaceans from Santa Cruz Territory, Patagonia, etc.; Smithsonian Mise. Coll., vol. 52, pp. 441-447, pl. 43, 1910), who regards it as a near relative of Jnia. Perhaps True is right; but the material on which the genus is based, a few fragments of a braincase and a cervical vertebra all distorted by pressure, is so scanty that an error is very possible. Hesperocetus is established by True (A fossil toothed Cetacean from California, etc.; Smithsonian Misc. Coll., vol. 60, No. 11, 1912, pp. 1-7, pls. 1-2) on the strength of the anterior part of a long, nar- row, lower jaw with long symphysis, with rows of rather strong, conical, slightly hooked teeth with wrinkled enamel. The teeth are placed rather wide apart and are separated by shallow depressions in the margin of the jaw into which the tips of the upper teeth pre- 80 ; SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 sumably fitted. True refers it provisionally to the family Jniude (=Platanistide), perhaps rightly ; there are other possibilities. * (Pp. 26 and 31.) True (A Review of the Family Delphinide ; Bull. U. S. Nat. Mus., No. 36, 1889, p. 10) believes he has observed a peculiarity in the relationships of the pterygoid that should distinguish Delphinapterus and Monodon from all other Delphinids and recall the Platanistids: “ that in the narwhal and white whale the pterygoid bones, instead of merely forming the walls of the posterior nares, extend backward in the form of broad plates across the optic canal and articulate with the squamosals.” But the case is different. We have to do with the bones which lie in the outer wall of the air-sac behind the palate. As may be seen in young or youngish skulls of Delphinapterus and Monodon, the pterygoid shares in the formation of the outer wall of the air-sac at the front only, in contrast with the condition in Pontistes, Pontoporia and Platanista in which it, recall- ing the Balenids and Physeterids, forms most of the outer wall (in Inia the outer wall appears to be mostly membranaceous). As in other Delphinids the palatine, frontal, ala magna, and squamosal all share in bounding the outer side of the air-sac, each contributing its section (special ossifications may also be present). In the Delphinids under discussion the outer side of the air-sac is merely ossified more extensively than elsewhere, a difference, however, which is one of degree only. “ (P. 35.) As reasons for believing that Neomeris and Phocena among recent Odontoceti are the ones which stand nearest to Zeu- glodon and Squalodon Abel (Dauphins Longirostres, 1901, p. 36) mentions the following: (1) that they still have traces of “ l’ancienne dentition hétérodonte,” (2) that teeth are still found (or more cor- rectly may be found) in the intermaxillary, and that the intermaxillary extends further forward than the maxillary, (3) that they still have traces of “Varmure dermique,” (4) that the nostrils are not pushed very far backward, and that therefore the parietal still extends up back of the frontal. Against this view there are the following objec- tions: (1) The form of the teeth in the two recent genera is not primitive ; fan-like broadened crown and single root is not the form of tooth that is found in the more primitive cetaceans of any kind. Conical crown and a trace of double root, in most of the teeth, is the transitional form between the tooth structure of the more primitive and the less primitive cetaceans. Even the anterior teeth in the jaws of Phocena may have fan-shaped crowns, where in the most primitive whales they are unicuspid and conical. (2) Teeth in the inter- no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 81 maxillary, and a slightly projecting intermaxillary, may also be found in Steno, Delphinus, and several other of the recent Delphinide. (3) There is no evidence that cetaceans are descended from mammals with bony armor ; the so-called dermal bones that were found on rare occasions with remains of Zeuglodon and Delphinopsis are too doubt- ful to prove anything; in the great majority of instances no dermal armor has been found with bones of Zeuglodon and other Archeoceti. The “ dermal armor,” that is, the small spots of more or less tubercu- late, mosaic-like skin, in Neomeris and Phocena 1s assuredly a new development. (See pp. 56-58.) (4) It cannot be correctly said that the nostrils in Phocena and Neomeris lie relatively far forward. It appears so merely because the anterior part of the face 1s somewhat shortened and the, braincase is unusually large. In reality the nostrils lie, with respect to the orbits and other surrounding parts, in the same position as in most Delphinids. Neither can it be said that the parietals are excluded from the upper side of the braincase to a less degree than usual. As may be seen in the young skulls the parietals in Phocena are widely separated by the large interposed interparietal quite as usual in other Delphinids. * (P. 35.)

Reichanst., vol. 55, pt. 2, 1905, pp. 384; 387, in the “Subfamily Phocenine ”’ because it has “ dermal armature.’’ The remains are so imperfect and so uncertain that it is impossible to say where it be- longs ; not even the family can be determined from the specimen; the reference to Phocenine is pure guesswork. Rhabdosteus was described in 1867 by Cope, who in 1890 (Amer. Nat., vol. 24, p. 607) gave figures of the specimens on which the genus was based, some remnants of a “ beak,” from a Tertiary North American deposit. These remains Cope reconstructed in a somewhat arbitrary manner. True (Remarks on the fossil Cetacean Rhab- ‘dosteus latiradix Cope; Proc. Acad. Nat. Sci., Philadelphia, vol. 60, 1908, pp. 24-29, pl. 6, and text figures), who has had the specimens in question under revision, together with some others more or less similar, says that Cope has scarcely put them together right. The specimens may recall Eurhinodelphis and its relatives ; but the remains are altogether too incomplete and uncertain for anything to be decided. Lophocetus, established by Cope in 1867, best known from East- man’s description (Types of fossil Cetaceans in the Museum of Com- parative Zoology ; Bull. Mus. Comp. Zool., vol. 51, 1907, pp. 79-94, pls. 1-4), Tertiary, North American, is most often placed in the Platanistide. Brandt, however, counts it as a Delphinid (1873, 1. c., p. 288), most probably belonging to the “ Abtheilung der Phoczenen,” perhaps to the genus Delphinapterus. In this determination he has been followed by a few other authors. The most important basis of the genus is a very imperfect skull, without teeth, with alveoli only, so obscure that nothing positive can be said about it. According to what can be seen of the form of the temporal fossa the genus appears to agree best with the Delphinids. On the other hand it does not seem possible to demonstrate anything that would especially recall the Platanistids. Imopsis was established by Lydekker (Proc. Zool. Soc. London, 1892, pp. 562-564, pls. 37-38) principally on an imperfect and obscure braincase from a Tertiary deposit in the Caucasus. Lydekker places it in the Platanistide and finds similarities with Pontistes, Stenodel- phis (=Pontoporia), Inia, etc. It appears, however, to be of another 86 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOR 72 type, very near the most usual Delphinid-type, differing from the Platanistide especially in the roofed over temporal fossa. Its more exact position among the Delphinids cannot yet be determined. Cyrtodelphis is only a new name for Schizodelphis given by Abel in 1899 (J. c.) to include a series of species which previously were most often referred to Schizodelphis, among them the type of the genus, S. sulcatus Gervais. Eastman (Bull. Mus. Comp. Zool., vol. 51, 1907, pp. 83-84) has already protested against this superfluous new name as well as against the following. Acrodelphis is likewise essentially a mere new name, a synonym of Champsodelphis. It was given by Abel in 1899 (J. c.). At first Acrodelphis was to include the type of Champsodelphis, Ch. macro- genius (Laurillard) Gervais or macrognathus Brandt. Later, in 1905, Abel excluded the type of Champsodelphis from the genus, with doubtful right; but most of the species which he now includes in Acrodelphis were earlier called Champsodelphis. Paleophocena was based by Abel (1905, Jahrb. k. k. geol. Reich- sanst., vol. 55, J. c.) on an imperfect piece of a braincase and a few fragments of the rest of the skeleton from a Tertiary deposit on the coast of Crimea. Abel considers it proved that this is a near relative of Phocena. Possibly it will sometime turn out that he is right; but for the present there is no means of deciding the question about nearest relationship. The known piece of skull shows only such general features that nothing exact can be said except that it comes from a Delphinid. Only in the form of the teeth have Phocena and its relative Neomeris a peculiarity which distinguishes them from other quite ordinarily formed Delphinids ; but the teeth in Paleopho- cena are not known. Protophocena is also established by Abel (Odontocétes du Bol- derien, 1905, pp. 139-141, with illustrations), on the anterior, very imperfect part of a skull, without teeth, from the Tertiary deposits at Antwerp. Abel refers it to the “ Phocenine.’ There is actually nothing whatever, apart- from the small size, that could lead one to think of Phocena,; on the contrary, the strong cushion-shaped swell- ing and the widening out which the intermaxillary shows in front of the nasal aperture suggests rather Lagenorhynchus or “ Grampus.” For the present the question about nearest relationship cannot be settled. Pithanodelphis is established by Abel (Odontocétes du Boldérien, 1905, pp. 142-145, with illustrations) on the basis of Phocenopsis cornutus du Bus from Tertiary strata at Antwerp. Abel refers it to no. 8 INTERRELATIONSHIPS OF THE CETACEA—WINGE 87 the “Delphinine.’ That which is known of it is an imperfect piece of a braincase and a few other parts. The characters, so far as they go, agree well with the ordinary dolphin type; the feature which especially distinguishes it is that the maxillary posteriorly is bowed inward unusually strongly behind the nasal. In this respect, how- ever, dolphins show great variation. The more exact position of the genus cannot be determined. Phocenoides is established by Roy Andrews (1911, lJ. c.) to include two recent species, one a new species, Ph. truei from Japan, the other a species which True had called Phocena dalli, likewise from the northern part of the Pacific Ocean. The deviations from typical Phocena are very small; perhaps the most noticeable is that the teeth are smaller, with the fan-like widening of the crown less pronounced. There can scarcely be sufficient ground for generic separation. Xiphiodelphis (“ Ziphiodelphis”’) (see especially Bassani e Misuri and Dal Piaz, 1912, J. c.) is established on fragments of skulls from Tertiary Italian deposits. There can be no douht that it is a near relative of Schizodelphis, etc., but its more exact position is not yet clear. Delphinavus is established by Lull (1914, J. c.) on an imperfect and compressed, indistinct skeleton from a no doubt Miocene deposit in California. The genus is supposed to stand very near to Delphinus in the narrow sense. The form of the palate, however, the only character that distinguishes Delphinus from nearly related Delphinids, does not seem to have been ascertained. One of the most important peculiarities is that the atlas and axis are mutually free. According to what is known it is not possible to clear up the relationship of the genus to other Delphinids; but it ought to be especially compared with Heterodelphis. * (P. 38.) It is Flower who has especially emphasized the differ- ence between Delphinids and Physeterids with regard to the relation- ship of the hindmost ribs to the vertebree. It is likewise he, in his paper on Jmia (Trans. Zool. Soc. London, vol. 6, 1869, pp. 98-100) and elsewhere, who has pointed out the intermediate position of the Platanistids. The question about the interpretation of the transverse processes, etc., had previously been discussed, among others by Esch- richt in his paper on Platanista (1851, pp. 369-370). Later it has been extensively dealt with by Gerstaecker (Das Skelet des Déglings, Hyperoodon rostratus, etc., 1887) and it is also taken up by Abel (Sitzungsber k. Akad. Wissensch. Wien, math.-naturwiss. K1., vol. 118, pt. I, 1909, pp. 247-249). 88 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL, 72 *(P. 43.)

L. BRITTON AND J. N. ROSE (PUBLICATION 2651) CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN INSTITUTION JUNE 15, 1921 at The Lord Baltimore Press BALTIMORE, MD., U. 8. A. < NEOABBOTTIA, A NEW CACTUS GENUS FROM HISPANIOLA By N. L. BRITTON anp J. N. ROSE (With Four Pirates) Among the earliest cacti described were those obtained by Plumier, more than two hundred years ago, mostly from the island of His- paniola, better known as Santo Domingo. These were characterized briefly by him in 1704 and his illustrations of them were published in 1755 by Burmann; Lamarck gave most of them binary names in 1783 under the genus Cactus, and in 1828 De Candolle referred all the cereoid forms to the genus Cereus; the other species described by Plumier have been referred by various authors to Mammuillaria, Cephalocereus, Pilocereus, Rhipsalis, Melocactus, Pereskia, Opuntia and Nopalea. We have experienced great difficulty in definitely identifying the plants from the illustrations of Plumier, since these are largely diagrammatic. As the type locality is generally given, however, the identification of all of them may eventually be made fairly definite. In 1920 when Dr. W. L. Abbott and Mr. E. C. Leonard were start- ing for Haiti, we asked them to collect both living and herbarium specimens of all the cacti met with. As good fortune directed, they spent a considerable time on the Cul-de-sac, where Plumier collected, and so probably obtained several of the species which he described. About 20 species of cacti were observed by them there. One of these, which has proved to be an undescribed genus, is the subject of this article. The Cul-de-sac is the bottom of an old salt lagoon, which now has an altitude of 20 feet or more above the sea. It is a coral formation and an ideal habitat for many kinds of cacti. Here they appear in thickets or literally as forests, forming the dominant feature of the landscape. This region lies north and east of Port- au-Prince, extending from the bay of Port-au-Prince to Lake Saumatre. After the return of Dr. Abbott and Mr. Leonard in September of the same year with these valuable specimens we wrote, at the suggestion of Mr. Leonard, to Mr. H. M. Pilkington, an American business man then stationed at Port-au-Prince, asking him to pro- SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 72, No. 9 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 cure additional material. In the latter part of December, 1920, Mr. Pilkington returned to New York and brought with him two large boxes of plants, containing two sections of the trunk, several living plants, and fruits of the new genus, as well as specimens of four other species, with field notes and photographs.

Collected near Port-au-Prince, Haiti, on the Cul-de-sac by Dr. W. L. Abbott and Mr. E. C. Leonard, April, 1920 (no. 3500) ; also at the same locality by Mr. H. M. Pilkington, December, 1920: also a single branch by Dr. Paul Bartsch at Thomazeau in 1917 (no. 221). Here doubtless belongs W. Buch’s specimen, described in a note under Cereus paniculatus by Dr. 1. Urban in his Flora Domin- gensis." This plant was described by Plumier* as follows: Melocactus arborescens, tetragonus, flore ex albido. This description was re- peated by Tournefort,’ with the addition of a single word, in 17109. Plumier’s drawing of this plant was published long after his death by Burmann as plate 192 of the Plantarum Americanum and upon this plate Lamarck based his Cactus’ paniculatus, which De Candolle ‘Symbol Antillane seu Fundamenta Flore Indiz Occidentalis, 8: 462. 1920. *Catalogus Plantarum Americanum, 19. 1703. * Histoire des Plantes, 1: 653. 17109. 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 a little later took up as Cereus paniculatus. Ever since, the plant has usually passed under the latter name, with an occasional reversal to the earlier one. Until recently, the species has been known only from this old illustration and these brief descriptions. The Abbott and Leonard material consists of wood sections and herbarium specimens of branches, flowers, fruit, and seeds, supplemented by living specimens and by fruit and flowers in formalin, together with several habit photographs. These convince us that the plant belongs to neither Cactus nor Cereus, but to an undescribed genus. In habit it resem- bles Dendrocereus, its branches resemble Acanthocereus, and the small limb of the flower resembles Leptocereus; but the plant differs from all of these in bearing several flowers at the ends of terminal branches and in developing a kind of cephalium. In the last respect it approaches Neoraimondia, near which we would place it in our present classification. ] Although at first Neoabbottia is weak and only 4-angled, suggest- ing Acanthocereus, it forms ultimately a thick woody trunk. The full-grown plant in habit and branches much resembles Dendrocereus nudiflorus of eastern Cuba, but it has much smaller and different flowers and seeds. The following remarks are from the careful field notes of Mr. Pilkington, made in December, 1920. “ Grows to a height of 50 feet, in light sandy arid soil of recent ocean bottom. Known to natives as ‘ Gadasse.’ No use is made of the plant except burning the dead branches for torches. The wood so used is called ‘ Bois Chandelle’ or ‘ Bois Flamboyant ’—‘ Candle- Wood’ and ‘ Flaming-Wood,’ from the bright smokeless light. Fruit falls when ripe; rind soon decays, leaving seed in a mass retained in shape by a mucilaginous pulp. The young plant develops a bul- bous root with a simple upright stem made up of several joints and later giving off lateral branches which come off from the upper end of other branches; the main stem is 4 to 6-winged, but as it grows older becomes square, pentagonal, or hexagonal, according to the original number of ribs on each joint, and in age terete or nearly so with the ribs showing as mere lines, bearing the scars of the old spines; the branches are more numerous on one side of the main branch and these always lie in the same plane, the ribs when of the same number being opposite those of the main joint. This dispo- sition of the joints causes the main stem to bend or curve and the whole has a striking resemblance to the flat antlers of moose and NO.Q NEOABBOTTIA, A NEW CACTUS GENUS—-BRITTON AND ROSE 5 elk. This arrangement is shown in the mature tree, although the intermingling of the several branches gives the general effect of an ordinary tree-top. “The natural pruning of the tree comes about through the death of branches caused by epiphytic plants, the breaking off of branches by the weight of a clambering cactus, and the attack of insects which live in the fleshy joints. These insects are much sought after by a red-headed woodpecker. ; “Flowers are borne at the extreme tip of the terminal joints and never from the sides, the fruit appearing therefore always at the tips. A single fruit always grows directly in line with a rib, but when several fruits grow from the same terminal bud they are compelled to radiate at right angles to the axis of the joint. Four fruits from one joint is the highest number observed, two only usually appearing to be normal. As the ovary develops the flower shrinks, dries, and appears finally as a brown protuberance attached to the apex of the mature fruit. The old flowers at length fall off the mature fruit, leaving a well-defined umbilicus. The fruit measures 6% to 7 inches in circumference. When ripe it is waxy, smooth, yellow with faint streaks of pink radiating from the base; flesh same color as rind, glutinous, firm, slightly acid to taste, hardly edible. “Seeds are embedded in a secretion which in water produces a remarkable bulk of mucilaginous jelly, which is mildly acid and not unpleasant to taste. Fruit does not seem to be attacked by birds and is never eaten by natives. Successive crops of fruit appear from this same bud cluster at the top of the terminal joint, each crop absorb- ing some of the substance of the joint ; the joint shrinks and solidifies, the ribs become furrows, the center enlarges, and finally all becomes a woody mass of varying dimensions, as long as 3 inches, thus forming what you have called a ‘cushion,’ but which is really an atrophied joint after several years of fruit-bearing.” The nature of the cephalium is not well understood, but it seems to be an abortive joint. It first appears like a large felted areole from which several flowers are produced; it slowly elongates and finally becomes 7 cm. long or more, still producing the flowers at the tip. When very old most of the felt wears off, leaving a stubby 4 or 5-angled joint ; the areoles, however, are not borne on the angles as in normal branches, but in the depressions or furrows between the ridges. In these furrows the areoles form a continuous band of felt from the base to the top of the joint. One of these flower-bearing joints which Mr. Pilkington has sent is 5 cm. long and we have esti- 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 7/2 mated that it has borne 20 sets of flowers and fruits and may possibly be 20 years old. While all the flowers we have seen are terminal, it is possible that they may sometimes occur from other places on the terminal joint. In one specimen examined we have found an enlarged areole near the base and one on the side of the terminal joint, which suggests that they had been flower-bearing. Plumier’s illus- tration, which is not accurate, shows numerous lateral flowers. The stubby tlowering joints, while usually solitary, appear sometimes in pairs.

ALDRICH INTRODUCTION The instrument about to be described is the outgrowth of the experience of Dr. Abbot and myself in the use of the pyranometer, and was planned in many discussions between us, as we walked together to and from the office. The pyranometer (described in Smithsonian Miscellaneous Collections, Vol. 66, Nos. 7 and 11, and Vol. 69, No. 9) has proved of great value in a wide range of radiation measurements. We have long felt the desirability and need, however, of a radiation measuring instrument of equal sensitiveness which would be perfectly absorbing and radiating for all wave- lengths by virtue of its form. Existing types of instruments, such as the pyranometer, bolometer, Angstrom’s pyrgeometer, compensa- tion pyrheliometer, etc., all use a blackened flat surface upon which the radiation falls and is mostly absorbed. -For the usual range of wave-lengths, for which the percentage absorption of the blackened surface is well known, these instruments are highly satisfactory. But in measuring radiations from bodies at comparatively low tem- peratures, grave doubt arises [with these instruments] because of the uncertainty of the absorptive power of a blackened flat surface for rays of long wave-length. In the new instrument we have tried to produce one embodying an approximately “ black-body ” absorber, and still to retain as far as possible the advantages of the simple pyranometer. The melikeron is not as sensitive nor as quick-acting as the pyranometer, yet we have been very well pleased with its behavior. A detailed description of the instrument follows. DESCRIPTION OF THE MELIKERON The name of the instrument, first suggested by Dr. Abbot, is the Greek word peduxnpoy, honeycomb. That portion of the instrument which absorbs the radiation to be measured is somewhat like a honey- comb in shape. SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 72, No. 13 - 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Sheet’ therlo,” an alloy having a low temperature coefficient of resistance, was rolled out into a strip about a meter long and as thin as possible. (In the first instrument made, this strip was about 0.05 mm. in thickness. This was about the limit of thinness obtain- able by rolling between cold rollers. For the second instrument, a strip of one-half this thickness was produced by rolling between hot rollers. This was done by the mechanician of the University of Wisconsin Physics Department, through the kindness of Dr. C. E. Mendenhall.) With a straight edge, the strip was cut to one-half inch in width, and then pressed out in a specially prepared die, to assume the alternately flat and zigzag shape shown in figure 3. When this long strip was held together in a square frame, there were formed 200 small triangular tubes with walls in common, each tube one-half inch in depth and about 2.5 mm. on a side. The open end of this honeycomb of triangular tubes forms the absorbing area of the instrument. The advantage gained by the large number of cells is that the outer ones protect the inner ones from loss of heat, so that notwithstanding the very large area of the walls of the cells compared to their open ends, the central cells, losing only at front and rear, change tempera- ture about as much as flat strips presenting equal areas would do for the same intensity of radiation. We invoke, in other words, the guard-ring principle. Before the long, crinkled strip was pressed into this square shape, each apex was coated with thin shellac, the whole baked in an oven for some hours, and this process repeated several times. Thus the whole strip, when formed into its final shape, was insulated, each part from every other that could come in contact with it, and a current of elec- tricity could be sent through its whole length. On the walls of the central cluster of tubes formed by the bending of the strip were fastened four thermo-electric elements, of fine copper and nickel wire. The junctions were symmetrically placed 2.5, 5.0, 7.5 and 10.0 mm. respectively along the length of the tube and insu- lated from it by thin tissue paper. These wires were brought out on the lower end of the tubes and connected in series. The constant temperature junctions were buried in wax on the under side of the glass plates f, f (fig. 2) and the outer leads were soldered to the bind- ing posts a, a, (fig. 1). The two ends of the therlo strip were con- nected by copper wires to binding posts a’, a’ (fig. 1). * Obtained from the Driver-Harris Wire Co. NO. 13 THE MELIKERON—ALDRICH 3 Referring to figures 1 and 2, we may see how the honeycomb is mounted. Figure 1 is a view looking vertically down upon the instru- ment with shutter (¢) wide open. Figure 2 is a vertical cross-section. Two nickeled copper plates (i, 1), each with square holes 3 cm. on a side are placed one about 6 mm. above the other. The plates are held @ 2 ----2] OO He, yy TULUM BLE WV AP nuanaaaaaay ie Fie. 3. together by the three posts (b) and the space between the plates around the square hole enclosed with’a copper box (m) attached to the upper plate. The wires leading to the four binding posts (a, a, a’, a’) pass through holes in this copper box. Four nickeled copper clips (c) are screwed to the top of the upper plate, and four more to the bottom of the lower plate. Each of these eight clips holds in 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 place a silvered glass plate (f), each of which glass plates is beveled along its inner edge. These beveled glass edges serve to support the therlo strip in its square form, four around the upper edge of the honeycomb and four around the lower edge. The upper four also serve to determine the area which absorbs radiation. The silvered glass mirror (g), below the honeycomb, is placed, as shown, at a small angle to the face of the honeycomb and serves both to protect from the wind and to reflect radiation escaping from the lower face of the honeycomb back upon the sides of the tubes. The rod (k) screws into the plate (1) and affords a means of mounting the instru- ment in any desired position. The hemispherical shutter, (¢), nickeled on the outside and blackened inside, operates from the handle (7), just as in the pyranometer. The optically figured ultra-violet crown glass hemisphere (d) serves the same purpose as in the pyranometer and may be used or not, according to whether or not it is desired to’ cut off the exchange of long waves between the instrument and the object to which it is exposed. The melikeron is similar to the pyranometer in principle. In place of a small flat absorbing surface we substitute a large absorbing area consisting of the above described honeycomb of triangular tubes. Radiation falling normally passes through and is reflected back upon the walls by the rear mirror. Radiation not falling normally strikes the walls of the tubes and after one or more reflections is absorbed. For the purpose of somewhat increasing the blackness of the honey- comb, only the lower two-thirds of each tube is painted with lamp- black, the upper one-third remaining a metallic reflector. Thus the number of regular reflections before final absorption is increased and the loss by diffuse reflection near the upper end reduced, because the diffusely reflecting and radiating lampblack lies so far below the aperture that the latter subtends only a small angular area as viewed from the blackened surface. METHOD OF USE For nocturnal radiation, or for the measurement of radiation exchange between the instrument and an object at lower temperature, the melikeron is used like the pyranometer. That is, an electric current is passed into the therlo strip producing heat sufficient to exactly compensate for the loss of heat by radiation. Knowing the current used, the resistance of the strip, and the other constants of the instrument, the amount of heat radiated is computed as with the pyranometer. NO. 13 THE MELIKERON—ALDRICH 5 For measurements on the sun, daylight sky, or any radiation from bodies at higher temperature than the instrument, the simple “ first- swing” pyranometer method is not applicable, since the slow-acting melikeron prevents a definite first-swing of the galvanometer and requires several minutes to complete the galvanometer deflection. An almost equally simple and satisfactory method applicable to constant sources of radiation was suggested by Dr. Abbot, however, namely: To open the shutter and expose to the radiation to be measured until the galvanometer deflection is constant, then close the shutter and instantly introduce sufficient current to keep the galvanometer at the same reading. CONSTANTS OF INSTRUMENTS AND TESTS MADE As mentioned above, two copies of the melikeron have been made. The second instrument embodies several improvements, notably a thinner therlo strip, and the tipping of the rear mirror at a slight angle to the honeycomb face. The constant of each instrument and tests made with each are given below. Melikeron No. 1—The constant of the instrument may be apeined in two ways: (1) By computation from the dimensions and properties of the instrument ; (2) By direct comparisons on the sun with a silver disk pyrhelio- meter or other standardized instrument. Only the first of these methods was used for the constant of Meli- keron No. 1. As compared with the second method, this method is difficult and inaccurate, because of the uncertainty of such corrections as the amount reflected from the end surfaces of the thin metal com- posing the tubes, the amount lost by reflection and radiation from the upper portion of the tubes, the decrease in total aperture due to the unavoidable indentations around the edge, etc. A rough determination was made of the computed constant of Melikeron No. 1, as follows: Area of aperture formed by beveled glass edges = 5.83 cm.” Estimated decrease in area of unused portions= .30 “ 6c Corrected area = 5.53 Resistance of therlo strip = 0.945 ohms. Then 945 X 60 = 2.45= constant Melikeron No. 1, appli- 4.183 X 5.53 cable to reduce C* readings to calories per (ar }. This is the constant without the glass hemisphere. With glass hemi- sphere, allowing for the reflection loss at two glass surfaces, the con- 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 stant becomes 2.66 for the rays of short wave-length for which glass is highly transmissible. Test experiments of three kinds were made with Melikeron No. 1: (1) Using an incandescent lamp source, comparisons were made by interchanging Melikeron No. 1 and Pyranometer A. P. O. No. 5.

To insure constancy of the source, storage batteries were used. ‘The results are summarized in table I. As would be expected, since in Melikeron No. 1 the rear mirror is perpendicular to the honeycomb tubes, the instrument does not mea- sure the full amount of radiation falling normally or nearly so, for this passes through the tubes to the rear mirror and is reflected by it directly back without being absorbed.

A flat copper vessel (fig. 4) 90 x 86 cm., blackened on the front surface by painting with lampblack-alcohol-shellac paint and filled with ice-cooled water, formed the source, the instruments being at room temperature. A double shutter (s), sliding horizontally close to the copper vessel, exposed or screened the source. The instru- ments could be quickly exchanged, each mounted with absorbing Fic. 4. Fic. 5. surface vertical, facing the copper vessel, and 65 cm. from it. Alter- nate comparisons were made with and without a 1 cm. rock salt plate (r), figure 4, interposed directly in front of the instrument aperture. Using the above computed constant of the melikeron, values of the constant of Pyrgeometer No. 22 were determined (table II). The absolute value of these results is of little weight, but the markedly lower value of the constant of Pyrgeometer No. 22 for the case where waves longer than 20 are excluded, seems to indicate the greater “blackness”? of the melikeron as compared with the other instrument for rays of very great wave-length. 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.. 72 (3) A rough determination of the constant o of Stefan’s formula was made. A wooden case and water jacket were fitted around Meli- keron No. 1 to protect it from temperature fluctuations of the sur- roundings. This jacket extended over the face of the instrument, leaving an aperture 3.64 cm. in diameter at 7.03 cm. from the honey- comb face. Two hollow-chamber black bodies were made of double walled galvanized iron vessels (a and 0, fig. 5) filled between the walls with stirred water, one at room temperature, the other containing a mixture of ice and water. The melikeron and surrounding jacket just filled the aperture of either of these black bodies, and could be quickly moved from one to the other aperture. The results are sum- marized. Details and necessary corrections which have been intro- duced in these results here will be found in the forthcoming Vol. IV, Annals of the Astrophysical Observatory. Temperature of 2 == (Current)?

They are given to show that not only does the melikeron agree with the standardized pyranometer for ' short-wave radiation observations but it also agrees well with the best work for long-wave rays. Melikeron No. 2.—The constant of this instrument was determined with more care, and by both methods above mentioned. (1) Computed constant.

Hence, the total correction for in- complete triangles is .054+.18=.234 cm.” Area of irregular indentations that can lose energy by direct radiation=.06 cm.? Of this, 4 is lost=.03 cm.?

Computed constant (without glass hemisphere) = 1.555 X60 4.183 X 5.50 = 4.05 (2) Observed Constant. The constant determined by comparison with pyrheliometers may be given more weight. The melikeron was mounted equatorially and a hood placed around it, similar to that supplied with the pyranometer, exposing the instrument only to the sun and a small area of sky around it. A double, ventilated shutter, blackened below, served to cut off the radiation at intervals. The first comparison was made on Mount Wilson, California, August 29 and 30, 1920, using secondary pyrheliometer No. IV. All the following values are without glass hemisphere. First determination—Melikeron mounted so that sun rays fall nor- mally on the instrument. Calories by Pyr.

The difference cannot be serious, however, because this correction is after all very small. IO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 the silvered surface of the rear mirror. Thus 3.95 is regarded as more nearly correct for ordinary work with beams which (unlike direct run-rays) subtend large angles. The second comparison was made at Mount Harqua Hala, Arizona, by Dr. Abbot, November 10, 1920, using secondary pyrheliometers Sz Li Now32and ASPAOTNora: First determination—Melikeron normal to sun’s rays. Calories by Pyr. No. 32 and No. 9 =1.531 (mean value). (Current)* of Melikeron—= .347 (mean value). 1.531 347 Second determination—Melikeron at 7° angle to sun’s rays (cos. 7° =.992). Calories by Pyr. No. 32 and No. 9 = 1.538 (mean value). (Current)? of Melikeron= .378 1.538 X .992 378 This result shows for normally incident rays a considerably greater absorption and scattering by the rear mirror than was the case in the comparison of August 30. From the deteriorated appearance of the silvered mirror on November Io this was quite to be expected for sun rays, but the deterioration was probably quite negligible for earth rays. The best constant, then, of Melikeron No. 2 without glass hemisphere is the mean of 3.95 and 4.04, or 4.00 which is now the adopted value, applicable for all rays not at strictly normal incidence. At Mount Wilson and Mount Harqua Hala numerous comparisons on the night sky were made between Melikeron No. 2 and Pyrgeo- meter No. 22. The two instruments, leveled, were mounted at the same height and within less than 6 inches of each other. Exactly similar bright tin-box shutters were used on both instruments. Using the above adopted constant of Melikeron No. 2, a value of the con- stant of Pyrgeometer No. 22 was obtained each time. The results are summarized in table III. The mean of all, under these varying conditions of air temperature and water-vapor content is 9.72. There is perhaps some evidence in these values that the constant of Pyrgeometer No. 22 is a function of both air temperature and water-vapor content. But further compari- sons under a wider range of air conditions are needed to confirm it. To illustrate this indication, values are given in the table computed by the formula: Constant = 11.50—3.12p—1.47 (t—60°)*%. = 4.41 = constant of Melikeron No. 2. = 4.04 = constant of Melikeron No. 2.

To increase either the humidity or the temperature is to diminish the proportion of the extreme long-wave rays.

SMITHSONIAN MISCELLANEOUS COLLECTIONS VOLUME 72, NUMBER 14 A NEW SAUROPOD DINOSAUR FROM THE OJO ALAMO FORMATION OF NEW MEXICO (WitH Two PLATES) BY CHARLES W. GILMORE Associate Curator, Division of Paleontology, U. S. National Museum (PUBLICATION 2663) CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN INSTITUTION JANUARY 31, 1922 The Lord Baltimore Press aber gly BALTIMORE, MD., U. S. A. : rc + , 7 a a NEW SAUROPOD DINOSAUR FROM THE OJO ALAMO FORMATION OF NEW MEXICO By CHaries W. GILMorE, ASSOCIATE CURATOR, DIVISION OF PALEONTOLOGY, UNITED STATES NATIONAL MUSEUM (Witu Two Piates) INTRODUCTION In a brief note* I have recently announced the discovery by Mr. John B. Reeside, Jr., geologist of the United States Geological Survey, of Sauropodous dinosaur remains in the Upper Cretaceous of New Mexico, and it is now proposed to give a more detailed account of the specimens and of their exact geological occurrence than was possible in the preliminary notice. The remains so far recovered consist of a left scapula and a right ischium, both in a good state of preservation. The great importance of these particular bones lies in the fact that the remains of Sauro- podous dinosaurs have not previously been known to occur above the Lower Cretaceous in North America, so that the extension of their geological range into the Upper Cretaceous is of the greatest paleon- tologic and geologic interest. Tt is particularly fortunate that this discovery should have been made by a trained geologist of Mr. Reeside’s attainments, and in a section so well established as to preclude the possibility of question as to their late position in the geological column. That these bones pertain to a member of the Sauropoda is indicated by their immense size and also by their close general resemblance to homologous elements of the typical Sauropoda from the Morrison formation. Marked differences in details, however, more especially in the ischium, in conjunction with the very late geological occurrence, makes it necessary to establish a new genus and species for their reception, for which the name Alamosaurus sanjuanensis is proposed. DESCRIPTION ALAMOSAURUS, new genus The characters of this genus are included in the following descrip- tion of the type species: 1Science (N. S.), vol. LIV, 1921, p. 274. SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72, No. 14 iS) SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 ALAMOSAURUS SANJUANENSIS, new species Plates I, 2 Type.—Cat. No. 10,486, U. S. N. M., consists of the nearly com- plete left scapula. Paratype.—Cat. No. 10,487, U. S. N. M., consists of the nearly complete right ischium. Type locality—Barrel Spring Arroyo, one mile south of Ojo Alamo, San Juan County, New Mexico. Horizon.—Ojo Alamo formation, Upper Cretaceous. Collector —J]. B. Reeside, Jr., June, 1921. The scapula and ischium designated as the type and paratype, respectively, were found in the same geological horizon, but some 200 feet distant from one another. While it is quite possible that both may pertain to the same individual, it is thought best to regard them as distinct until their closer relationship can be more positively established. Scapula.—The scapula is in a good state of preservation except for the loss of a portion of the proximal or articular end (see pl. 1) where it projected above the ground and was weathered away. The suprascapular end is also incomplete, though apparently only the border is missing. In size this bone rivals the largest of the Camara- saurus scapulae described by Messrs. Osborn and Mook,’ since as preserved its greatest length is 155 cm. (60 inches), and it is con- servatively estimated that the total length of the complete bone would have been at least 170 cm. (68 inches). In outline, as shown in plate 1, the blade of the scapula differs from any described form in that there is a gradual widening of the shaft - from below upward to the superior end, there being no especial expan- sion of the anterior border as found in Camarasaurus, nor rapid superior expansion of both borders as found in Diplodocus and Haplocanthosaurus. While this portion of the bone is heavy it is not so massive as in Camarasaurus, being much thinner. The superior end is flattened out, though the external surface becomes convex trans- versely as the middle of the bone is approached. From end to end the bone is curved as in other members of the Sauropoda. Both anterior and posterior borders thin out to sharp edges, this condition continuing downward half its total length. Immediately above the point where the anterior border begins to turn upward to form the prescapular expansion of the lower end the border becomes thick- *Memoirs Amer. Mus. Nat. Hist., new ser., vol. 3, pt. 3, 1921, p. 341, fig. 74 NO. I4 A NEW SAUROPOD DINOSAUR—GILMORE 3 ened and rounded. The posterior border, however, continues down- ward as a fairly sharp edge to the downward swing of this border to form the glenoid socket where the bone rapidly thickens transversely. The spine or ridge on the lower external surface extends from the base of the shaft’ in an anterior direction to the anterior-superior border, and at right angles to the longitudinal axis of the bone. This ridge is not greatly elevated except that on the side toward the cora- coidal border the bone is rapidly and deeply excavated, forming a muscle fossa of great extent. On the upper side of this ridge the surface of the bone slopes off gradually to the border, there being no excavation or superior fossa such as is found in so many Sauropod scapulae.

This bone differs so from other Sauropod ischia that its true nature was determined with difficulty. That it pertains to a member of the Sauropoda is indicated by its large size and also by its general resemblance, though differing markedly from any described form. It is characterized by its extreme shortness, and especially by the lack of the long, slender posterior extension so characteristic of other Sauropod ischia. The proximal portion is nearly complete, lacking only a small por- tion of the sharp inner edge of the acetabular border. The distal end, though not perfect, apparently lacks but little of being complete. Likewise the thin inner border below the articulation for the pubis is slightly imperfect. Except for the missing portions mentioned, the bone is in a remarkably fine state of preservation. The expanded proximal end is unusual, not so much because of its great antero-posterior extent, but on account of the great dorso- ventral diameter, and especially the great length of the pubic articula- tion which extends distalward more than one-half the total length of the bone. Below the pubic articulation the inner border presents a thin, sharp edge, and the flattened distal portion gradually diminishes in width to the distal end. This end is apparently without distal 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 expansion, though the incomplete surfaces makes this point slightly uncertain. Neither can it be definitely determined whether the ischia met on the median line, though I am inclined to think they did. The rounded and somewhat thickened posterior border is deeply concave from end to end. The sweep downward from the iliac articulation is especially pronounced. On the posterior external surface at the mid- length of the bone is a raised ridge with roughened surface marking the point of insertion for a strong muscle. The form and principal features of this bone are well shown in plate 2: MEASUREMENTS Cettinenees Greatest length aces pile eee See hoe eee Otel ee ae 81 Gireatestawic tho ta pro xt e tC rs yeyeeseery- ce eee ee teen 44.5 Greatest width at lower end of pubic articulation............ 2 Greatest lensthiion pubic artetlarisun faces srr ieee B75 Greatest transverse diameter of articular end for ilium...... 10.5 RELATIONSHIPS The scapula cannot be closely correlated with any of those of described genera, and the ischium differs so much in its details from those with which it has been compared as to indicate an animal with a considerably different pelvic structure than any of the Sauropoda with which we are acquainted to-day. That both of these bones pertain to the same individual cannot be proven, but that both are Sauropod in aspect seems certain. In size the scapula approaches Camarasaurus, but it differs by the non-expansion of the upper anterior border and the very much thinner blade; from Diplodocus it is to be distinguished by its larger size and the direction of the spine in relation to the longitudinal axis. In the present specimen this angle is approximately 90°, whereas in Diplodo- cus and Amphicoelus it is acute. The scapulae of Apatosaurus, Amphicoelus, and Brachiosaurus are more slender and with a much more constricted shaft at their narrowest width. Haplocanthosaurus is very much smaller and has a very different outline. GEOLOGICAL OCCURRENCE At my request Mr. Reeside prepared the following note on the stratigraphy : NOTE ON THE STRATIGRAPHY OF SAN JUAN COUNTY, NEW MEXICO, WITH ESPECIAL REFERENCE TO THE OCCURRENCE OF DINOSAURS The oldest rocks exposed in San Juan County, New Mexico, have been assigned to the McElmo formation of Jurassic or Lower Cretaceous age. The overlying rocks, of Upper Cretaceous and Tertiary age, have been divided into NO. 14 A NEW SAUROPOD DINOSAUR—GILMORE 5 a number of units named in ascending order as follows: Dakota sandstone, Mancos shale, Point Lookout sandstone, Menefee formation, Cliff House standstone, Lewis shale, Pictured Cliffs sandstone, Fruitland formation, Kirt- land shale with included Farmington sandstone member, Ojo Alamo sandstone, Puerco formation, Torrejon formation, and Wasatch formation. The Point Lookout sandstone, Menefee formation, and Cliff House sandstone comprise the Mesaverde formation of the older literature and the Pictured Cliffs sand- stone, Fruitland formation, and Kirtland shale, the Laramie formation. The Dakota sandstone contains coal beds and other plant remains and grades into the overlying Mancos shale. The formations from the Mancos shale to the Pictured Cliffs sandstone, inclusive, are marine except parts of the Menefee formation which are brackish and fresh water deposits with coal beds. The lower part of the Fruitland formation contains a transition series of brackish water beds and the upper part and all of the overlying formations are fluviatile deposits. The Mancos shale represents in large part the Benton shale and Niobrara formation of the region east of the Rocky Mountains. Its extreme upper part, however, is the equivalent of the basal part of the Pierre shale. The Mesaverde group, Lewis shale, and Pictured Cliffs sandstone contain invertebrates of Montana age, and the Fruitland and Kirtland formations, plants, invertebrates, and reptiles of Montana age. These beds definitely assignable to the Upper Cretaceous, 7. ¢., from Dakota sandstone to Kirtland shale, inclusive, are a comformable series 5,500 feet thick, of which about 4,000 feet are of Montana age. The age of the Ojo Alamo sandstone is in dis- pute. It has been assigned by some writers on the basis of its dinosaur fauna to the Montana group and correlated with the Judith River beds. It is separated from the Kirtland shale by a widespread unconformity and has been correlated on that ground by other writers with the Denver and Raton forma- tions of post-Montana age. The Puerco and Torrejon formations contain large mammalian faunas and are usually placed in the Tertiary, though some writers would place them in the Cretaceous. The Wasatch formation is uni- versally accepted as Tertiary. Dinosaur remains have been found in the Fruitland formation, throughout the Kirtland shale, and in the Ojo Alamo sandstone. The sauropod bones found in June, 1921, came from the lower part of the Ojo Alamo sandstone on Barrel Spring Arroyo, one mile south of Ojo Alamo.

Attention is directed whenever possible to regions which have previously been imperfectly explored from a scientific point of view, and during the seventy-five years of its existence, the Institution’s field parties have been able to make notable additions to existing knowledge as well as to provide vast col- lections of biological, zoological, and anthropological material for the exhibition and study series of the United States National Museum, a branch of the Institution. During the past year, the effectiveness of the Institution’s limited funds for this work has been so reduced by the prevailing high costs that it was not possible to take part in as many expeditions as is customary. The more important of those which did take the field are briefly described in the present pamphlet, which serves as an announce- ment of the results obtained, many of the expeditions being later treated more fully in the various series of publications under the direc- tion of the Institution. The photographs here reproduced were for the most part taken by the field-workers themselves. GEOLOGICAL EXPLORATIONS IN THE CANADIAN ROCKIES The geological work by Secretary Charles D. Walcott in the Canadian Rockies was in continuation of that of the field seasons of 1919, 1920, for the purpose of securing data on the pre-Devonian strata of the Sawback range in Ranger Brook Canyon, and a recon- naissance of the pre-Devonian formations to the northwest as far as the headwaters of the North Fork of the Saskatchewan River, Alberta. The season was an unusually cold and stormy one. The party started with a pack train from Banif, June 30, and returned September 30. During this period there were 35 stormy days, 28 cloudy and cold days (20° to 45°) and more or less snow fell on 20 days in August and SMITHSONIAN MISCELLANEOUS COLLECTIONS.

While on the trail 30 camps were made, but owing to weather conditions and to the fact that the snow remained on the slopes and cliffs above timber line, a relatively small amount of productive work was accomplished. The section studied near the head of Ranger Brook Canyon of the Sawback Range about 12 miles (19.3 km.) northwest of Banff, was from the base of the Devonian limestones down through the post- Cambrian (Ozarkian) Mons formation and the subjacent Lyell and Sullivan * formations of the Upper Cambrian. Fic. 8—Camp on the lower eastern slope of Fossil Mountain looking north toward the head of Red Deer River. The character of the formations is indicated by figures 2 and 3, which show the southwesterly slope of the highly inclined beds (45° to 70°) and the saw-tooth-like effect caused by the unequal rate of erosion of the massive bands of limestone and the softer, more friable sandy and clay shales. Towards the northwest end of the Sawback range at the Red Deer River the Black and White Douglass mountains stand high above the surrounding ridges. (Fig. 5.)

It has a good section of Devonian and Fic. 10.—Wild flower camp on northwest side of Johnson Creek Pass. (Mrs. Mary V. Walcott, z921.) pre-Devonian rocks on its eastern slope. There is a fine outlook from camp at the east foot of the mountain. The broad U-shaped valley (fig. 9) between Fossil and Oyster mountains has been eroded in the shale and thin bedded limestones that pass beneath Fossil Mountain; this formation is one of those in the Sawback Range that is readily worn away, with the result that the agencies of erosion followed by the glaciers have made a valley al- together disproportionate to the present erosion agencies, water, frost and snow. At a camp in the heart of the Sawback Range on a tributary of Baker Creek leading up to Johnson Pass there was a wonderful NO. 15 SMITHSONIAN EXPLORATIONS, I921 9 exhibit of wild flowers in bloom. Mrs. Walcott counted 82 species within a short distance of the tents. A spring-fed pond supplied camp water; dead pines and spruce, firewood; and a grass covered snow- slide slope, abundant feed for the horses. The moss pink (fig. 11) and the beautiful Dryas octopetala were very abundant, but heavy frosts in August killed nearly all the plants and few of the flowers went to seed. On our way north we crossed over Pipestone Pass and down the Siffleur River. Clearwater River heads in glacial gravels on the east side of the Siffleur about two miles north of Pipestone Pass. Figure 13 is a view looking west through the Clearwater Pass and across to the high cliffs on the western side of Siffleur Canyon. Twenty-five miles further to the northwest at the point where the south branch (Mistaya Creek), the middle branch (Howse River), and the north branch unite to form the Saskatchewan River, there are some beautiful and instructive views of the surrounding mountains. Figure I (frontispiece) is a fine view of the head of the river, with Howse River in the left background and the North Fork beyond the island on the right. The Mount Forbes massif on the left is a superb mountain mass and in the distant center is Division Mountain at the head of Glacier Lake Canyon which we visited in 1919; on the right Survey Peak and beyond two unnamed points. The Glacier Lake section of the pre-Devonian and Upper Cambrian formations was studied on the northern slopes of the Mount Forbes massif as illus- trated by figure 1 (frontispiece) of the Smithsonian exploration pamphlet for 1919, and the rugged cliffs and peak of Mount Forbes are shown by text figure 14 of the present number. Twelve miles northeast of Mount Forbes the cliffs of Mount Murchison (fig. 15) rise high above the dark forested slopes and present a view of the Devonian and pre-Devonian formations that is unequalled in all this region of peaks, cliffs and broad canyon valleys. Opposite Mount Murchison on the north side of the Saskatchewan, Mount Wilson (fig. 16) presents another section of the pre-Devonian formations, the upper end of which is a massive white quartzite formed of the sands of the beaches over which the Devonian Sea deposited thick layers of calcareous sediments abounding in the remains of corals and various invertebrates of the time. On the west, Mount Wilson rises directly above the North Fork of the Saskatchewan which here flows through a narrow picturesque inner canyon (fig. 17). 1Smithsonian Misc. Coll., Vol. 72, No. 1.

Thompson Pass is one of the scenic features of the Continental Divide when viewed from the high Alpine valley on the northeast side of Castleguard Canyon. The Pass is low (6,511’ or 1,984 m.), and bold high ridges lead up to mountain summits on either side (fig. 4). A view taken on a misting day shows Watchman Lake (6,050’ or Fig. 24.

The Castleguard glaciers flow down from Mount Castleguard (10,090’ or 3,075 m.), which is a fine peak a few miles northeast of Mount Bryce. Figure 4 is a fine illustration of a misting day along the Continental Divide. We were camped for a week on the south side of the Alpine *Smithsonian Misc. Coll., Vol. 72, No. 1, 1920, p. 15. 22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 upland in the foreground, and on each day numerous squalls of fine snow or frozen mist would sweep over from Thompson Pass or Bryce glacier. I do not know the origin of the names of Rice and Bryce, but it is probable that the mountains were named in honor of Sir Cecil Arthur Spring-Rice and Lord James Bryce. As the result of unfavorable weather not more than one-third of the work planned was completed when the late September snow drove us back to the railroad. The morning we broke camp to go to Lake Louise Station the horses were pawing away the snow to get at the grass beneath (fig. 23), and the snow was very beautiful on the trees and along the stream below camp (fig. 24). The trail was obscured by it and to make matters more complicated, snow driven by a strong east wind beat into our faces during the seven hours march. The next day the sun came out and the storms were forgotten except for the wonderful snow scenes along the trail down the Pipestone River. The Commissioner of the Canadian National Parks, Hon. J. B. Harkin, and the members of the Parks Service in the field, from Superintendent to Park Warden, were most helpful, and the same is true of the officials and employees of the Canadian Pacific Railway. PALEONTOLOGICAL FIELD-WORK IN THE UNITED STATES Field-work by the Department of Geology of the U. S. National Museum during 1921 was carried on by three members of the Division of Invertebrate and Vertebrate Paleontology. Dr. R. S. Bassler, Curator of the Division of Paleontology, in cooperation with the Geological Survey of Tennessee spent the month of July in field-work in the Central Basin of that State, where he was occupied in collecting geologic material and in mapping and studying the economic resources of the Franklin quadrangle in Williamson County, south of Nashville. This area of about 250 square miles is of economic interest, on account of phosphate and oil shale possibilities. It is also classic ground for the paleontologist because of the numerous outcrops of Ordovician and later Paleozoic forma- tions which afford a wealth of fossils. During the course of the mapping, Dr. Bassler was able to collect a considerable number of these fossils needed in the museum study series and was also fortu- nate in securing several large exhibits illustrating various geological phenomena. Among the latter is a large mass of limestone composed entirely of the dismembered calices and columns of a large species of crinoid or sea lily in which the individual fragments are perfectly INO: 15 SMITHSONIAN EXPLORATIONS, I92I 23 ca Fic. 25.—Contorted and cross bedded phosphate rock, Franklin, Tenn.

Material was also secured, both for the exhibition and study series, illustrating the origin of the phosphate beds of the locality through the removal from a phosphatic limestone of the easily soluble calcium carbonate by the leaching power of surface waters. Such material is represented in figure 25 showing a rock outcrop where a porous limestone is over- laid by the contorted and crossbedded rock which upon such leaching gives rise to the phosphate. Among the interesting stratigraphic results secured was one show- ing the efficacy of coral reefs of the Ordovician in rock formation. The massive limestone about fifteen feet thick shown in figure 26 represents a middle Ordovician formation here containing but a single reef but within a distance of ten miles the number of intercalated coral reefs has so increased that the formation attains a thickness of over 250 feet. An ancient Indian village near Brentwood, Tennessee, was visited during this trip in the interest of the Bureau of Ethnology. The object of the visit, namely the determination of the length of time since the village was deserted, proved to be, however, outside of the domain of geology. Upon the completion of this work Dr. Bassler proceeded to Spring- field, Illinois, where with the permission of Dr. A. R. Crook, Chief of the Museum, he prepared casts of the type specimens of invertebrate fossils contained in the [linois State Museum collections. The aim in this work is to make the national collections of invertebrate fossils as complete as possible in its representation of type specimens, a work which was further advanced in the early part of January by a visit to the Walker Museum of the University of Chicago, where the casting of all the Paleozoic species which had remained unfinished on the occasion of a former trip was completed. Through the courtesy of Mr. E. J. Armstrong, of Erie, Pennsyl- vania, Dr. Bassler was enabled to visit all the classical Silurian and Devonian localities in northwestern Pennsylvania and western New York during the latter half of September. The object of this trip was to obtain a field knowledge of the detailed geology and to collect carefully selected sets of fossils illustrating the numerous formations of this region. This work was successful and the many large collec- tions of Devonian fossils in the museum hitherto lacking exact strati- graphic data can now be determined and arranged in the detail neces- sary to-day. INOS eS SMITHSONIAN EXPLORATIONS, I9Q21 25 In April, Mr. C. W. Gilmore, the Associate Curator of Vertebrate Paleontology was authorized to undertake a trip into New Mexico, “for the purpose of making collections of geological material for the National Museum and determining the advisability of preserving certain lands in northern New Mexico for national monumental pur- poses.” Mr. Gilmore was obliged to report that: 9 Since the many square miles of “bad lands” surrounding the reserved area are equally fossiliferous and in places present much more favorable territory for the recovery of fossil remains than any observed within the boundaries of the monument, and also since the greater part of these surrounding areas lie within Pueblo Grants over which federal control has been relinquished, there would be no advantage in retaining governmental control of so small a part of the area as is represented in the proposed monument. Mr. Gilmore did, however, find a contiguous fossiliferous area in the Santa Clara Pueblo Grant and secured for the museum a well- preserved skull and other bones of a small rhinoceros, and in an ad- joining Pojoaque Pueblo area remains of an extinct camel. The most promising area for collecting would appear to lie within land grants over which the government has at present no control. In January, this same year, Mr. J. W. Gidley, Assistant Curator in this Division, was authorized in cooperation with the United States Geological Survey to conduct field explorations in the San Pedro and Sulphur Springs Valleys of southern Arizona and on the completion of this work to visit the La Brea asphalt deposits of southern Cali- fornia and from there go to Agate, in Nebraska, for the purpose of securing other exhibition material. The work in Arizona was eminently successful, Mr. Gidley shipping some 24 boxes having an aggregate weight of 5,000 pounds. The bulk of this collection, he reports represents “a practically new Pliocene fauna containing about 60 vertebrate species, most of which are mammalian.” In detail Mr. Gidley reports essentially as follows: “ The geological structure of the San Pedro Valley will be published in detail by Doctor Bryan of the United States Geological Survey. It, however, may be noted here that this beautiful desert valley, now drained by the Rio San Pedro (which, rising near the Mexican border, runs nearly north-northwest, emptying into the Gila River, more than a hundred miles away), narrows and deepens as it runs northward from Benson leaving relatively small and scattered areas of sedi- mentary deposits which may contain fossil vertebrate remains. Most of our work, therefore, was confined to the upper valley, which forms a rather wide basin bounded on the east by the Dragoon mountains, on the west by the Whetstone Range, and on the south by the Tomb- 26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 stone mountains, and extends northward a few miles below the town of Benson. ‘ Erosional exposures in this general region are quite extensive, but time and funds being limited the work done on this expedition was confined entirely to two promising localities of relatively small area, previously located by Doctor Bryan. One of these is situated on the west side of the valley, about two or three miles due south of Fic. 27—General view of fossil bearing exposure at Curtis Ranch locality, looking across the San Pedro Valley.

Benson, the other on the east side, at the head of a large ‘ wash’ three miles east of the Curtis ranch which is situated on the state road about 14 miles south-southeast of Benson and an equal distance northwest of Tombstone. The latter locality occupied the greater part of my time and yielded by far the greater amount of material, although the number of species later collected in the Benson locality, slightly exceeded those found here. “ Among the larger, and, from the museum standpoint, more im- portant specimens secured at this locality are included parts of two skeletons of a new species of mastodon, and parts of three skeletons of a large armored edentate, Glyptotherium, which when restored should make a striking exhibition piece.

As found ona previous visit the conditions were not such as would inspire enthusiasm over the prospects of a good collecting-field. The surrounding country stretched away for miles in every direction almost as level as a floor, with no erosional exposures ; and had not recent fossil remains already 28 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 been discovered through the digging of a shallow well in the vicinity no one would have suspected their presence here. Several years earlier fossil bones had also been found at nearly the same depth (about 9 feet) in another well, now filled in, which had been dug at a distance of about 250 feet from the present open one. It was thus assumed that the fossil-bearing gravel deposit was of rather wide extent, and that by making a long stripping with plow and scrapers, a considerable area of “ pay gravel” might be uncovered and worked at comparatively small expense. The spot chosen as being most promising was naturally that between the two wells. “At Willcox, the services were procured of a reliable man with teams, plow and scrapers and this work was put into execution. Thanks are here due Mr. Harris, a local real estate agent, who lent valuable aid in this connection. I was also indebted to this gentleman for permission to put through the project, for the locality worked was on deeded land which he had in charge. “As the stripping progressed, it became evident that the strata, or layers, of deposits passed through did not conform to the section exposed in the abandoned well. Hence, on reaching the 7-foot level three prospect holes, about 15 feet apart, were put down to a depth of about 6 feet, or 4 feet lower than the top of the gravel deposit in the well. In none of these holes was there any sand or gravel en- countered thus proving that the gravel exposed in the well was part of an ancient stream channel of limited lateral extent. This discovery of course caused a complete abandonment of the trench excavation work, and the remainder of our time was spent in ‘ mining’ the gravel from the sides of the well as far as was considered safe to do so. In this way several good fossil horse teeth were procured. “From Willcox, I went by way of Tucson to Feldman, arriving there about noon of the 29th of March, where I was joined by Dr. Bryan. Feldman is a ranch and post office in the lower valley of the San Pedro, about 90 miles north-northwest of Benson and about 10 miles above the junction of the San Pedro with the Gila. The valley here is very much narrowed and deepened, the river bed being nearly 2,000 feet lower than at the Curtis ranch. The gradient of the streams and ‘ washes’ emptying into the San Pedro in this vicinity is very steep and benches and divides rise quite abruptly on either side. Erosional exposures one might expect to find here under these conditions are very much reduced by a heavy covering of gravel of relatively recent age. But paleontological evidence for confirming the age of this part of the valley was so much desired, a special effort INOS U5 SMITHSONIAN EXPLORATIONS, 1921 29 Fic. 29.—Base of skull of mastodon with tusks in position, partially excavated.

However, the few days spent here met with little success, and owing to the great inconvenience of continuing it further without more complete field equipment, the project was abandoned. On the morning of April 2, we left Feldman, returning to Benson via Tucson, and the next morning began a systematic search for fossils at a locality about two to three miles south of the town. During our earlier stay at the Curtis ranch we had made one short visit to this locality, the material obtained then sug- gesting a slight difference in age, or phase, between these deposits and those of the Curtis locality. The material obtained at this place is fragmentary and abounds mostly in remains of mammals of small size, intermixed with which were bones of birds of several species sufficiently well preserved for their determination, and a new species of box turtle. Here remains of thirty-four species of vertebrates were recovered. This collection, together with the material obtained at the Curtis ranch locality, in which 26 species are represented, makes up a very considerable fauna which should not only do much toward definitely determining the age of the beds of the San Pedro Valley, but will also throw valuable added light on the at present very little- known animal life of the upper Pliocene of America.” From Arizona, Mr. Gidley proceeded to Los Angeles; California, where he passed a week studying the museum of the southern branch of the University of California and in examining the well-known asphalt bone deposits of the Rancho la Brea. From Los Angeles, he proceeded on the 16th of April to Agate, Nebraska, prepared to carry out a second detail of field-work mentioned above. He was unfortu- nate here in encountering bad weather, but succeeded in securing for the museum a block of the bone-bearing sandstone some 34 by 54 feet and 14 inches in thickness. This was shipped to the museum and preparation for exhibition is now under way. ASTROPHYSICAL FIELD-WORK IN ARIZONA AND IN CHILE As stated in last year’s Exploration pamphlet,’ the solar radiation work of the Smithsonian Astrophysical Observatory was removed from Mount Wilson, California, to Mount Harqua Hala, Arizona, in September, 1920, in order to observe under better sky conditions, and in a more favorable place for continuing the observing the whole year round. Under the charge of Dr. C. G. Abbot the work was * Smithsonian Misc. Coll., Vol. 72, No. 6. NO. 15 SMITHSONIAN EXPLORATIONS, I92I 31 established and continued at Mount Harqua Hala until January 20, 1921, when it was taken in charge by Mr. L. B. Aldrich. He remained until May 20, 1921, when he was relieved by Mr. A. F. Moore, formerly director of the Smithsonian private observing station at Calama and Montezuma, Chile. Under Mr. Moore’s charge, the work has been continued steadily at Mount Harqua Hala, with the assistance of Mr. F. A. Greeley. The Smithsonian Institution maintains from the income of the Hodgkins fund a similar station at Mount Montezuma, near Calama, Chile, under the direction of Mr. L. H. Abbot assisted by Mr. P. E. Greeley. From this Chilean station daily telegrams are forwarded to Buenos Aires, Argentina, giving the observed value of the solar constant of radiation for the day. These data are employed regularly by the Argentine Weather Bureau for weather-forecasting purposes. While the Smithsonian Institution is not yet in position to champion the use of statistics of solar variation for meteorological forecasts, the great interest which its studies of solar variability have aroused here and abroad seems clearly to warrant the continued maintenance of the Arizona and Chile solar stations under the best possible observ- ing conditions for several years, until a satisfactory basis for a test of the solar variability as a weather-forecasting element has been laid. The present year has unluckily proved unfortunate at both stations. At Mount Harqua Hala the spring months were very hazy, the summer and autumn months unusually cloudy, with almost unpre- cedentedly heavy rainfall. At Montezuma the cloudiness of the earlier months was quite unprecedented. During August and Sep- tember a disarrangement of the apparatus caused apparently by earth- quake, combined with illness of the director, led to the loss of many observing days. In October, Dr. Abbot began an inspection trip to Montezuma, arriving at the station on November 15, and remaining until December 14. During this interval of 30 days, the observers fortunately were able to determine the solar radiation on 26 days, and generally with three or four closely agreeing determinations per day. All of the apparatus was readjusted and improved to the most perfect state of fitness. Many of the results in these conditions proved of a higher grade than ever before observed. In fact it would be hard to con- ceive of anything which could add now to the excellence of the Montezuma station and outfit. The accompanying illustrations show the desolate, rainless char- acter of the region ; figure 31 shows the mountain top with the observ- 32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL, 72 Fic. 31—Summit of Mount Montezuma.

The observing cave near the top of the mountain is less than 10 minutes walk from the observer’s quarters. It is only necessary to go up twice a day, once to observe, and again at 8.30 P. M. to signal the observed value to Calama, whence it is telegraphed to Buenos Aires. BOTANICAL EXPEDITION TO THE ORIENT During the summer and fall, 1921, Dr. A. S. Hitchcock, system- atic agrostologist of the Department of Agriculture and custodian of the section of grasses of the Division of Plants in the U. S. National 34 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL, 72 Museum, visited the Orient for the purpose of collecting and studying the grasses, especially the bamboos. He left Washington April 25 and returned December 23, visiting the Philippines, Japan, China, and Indo China. Six days were spent at Honolulu on the way over. Collections were made at the following places: Philippines, Manila, Los Banos, Baguio; Japan, Keelung (Formosa), Yokohama, Tokio, Nikko, Lake Hakone, Mount Fuji, Kyoto, Nagasaki; China, Shang- Fic. 34.—A peasant’s hut near Gotemba, Japan.

The countries were visited in the order named so that collections might be made at the most favorable season for grasses. Collecting in the vicinity of Manila is not very satisfactory as the native flora has been largely replaced by introduced species. From Los Banos, the seat of the Agricultural College, a trip was made to the summit of Mount Makeling about 3,500 feet high. This moun- tain is of especial interest to botanists as it is the most accessible region for the virgin forest, most of which has disappeared from the vicinity of Manila. On this mountain was met one of the worst pests of the eastern tropics, the leeches. At upper altitudes in the rain NO. 15 SMITHSONIAN EXPLORATIONS, I92I 35 forest these vile worms are found in countless numbers. They attach themselves to the skin and suck the blood with great avidity and con- stant vigilance is necessary to prevent serious damage. Japan is not very favorable for the collecting of grasses as it is mostly a forested region and there is comparatively little open country. The bamboos were of interest as there are many species. In the Lake Hakone region the hills were covered for miles with a single : wae. Coats is Fic. 35.—Hills near Lake Hakone, Japan.

China on the other hand was very rich in grasses. One of the surprises of the trip was to find so much open grass land in a country that is said to be very thickly populated. The cities of China are very much crowded and the valley lands are intensively cultivated, but the hills are unoccupied and almost unused. This is in striking contrast to our own western regions where, except in National Forests and other protected areas, the grass lands are extensively grazed. The basic reason for this condition in China appears to be the risk from bandits. The valley lands can be protected but the hills are open to the attack of robbers. 36 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 China was entered at Shanghai, a large comparatively modern city, much under the influence of foreigners. Here is the only American post office outside of the United States or its possessions. Mail can be sent from here under frank or with United States postage stamps.

Here forty- six species of grasses were obtained in a few hours on the sandy areas and rocky hills. Haiphong is the port of Tongking. Indo- China is a French Colony (officially French Indo-China), consisting of five divisions, Tongking, Annam, Cambodia, Cochin-China, and Laos. The objective in Indo-China was Hue, the capital of Annam. Loureiro, a Portuguese botanist, resided here and published in 1790 a flora of Cochin-China and it was to determine the identity of many of NOZ 15 SMITHSONIAN EXPLORATIONS, I92I 41 his grasses that this interesting city was visited. To reach Hue one goes by rail to Hanoi and then south to Vinh, the present terminus of the railroad that is to be built to Hue and ultimately to Saigon. Beyond Vinh one goes by auto-bus over good roads about 175 miles. A trip was made to Tourane on the coast, connected with Hue by railroad. On the return trip from Haiphong to Honkkong, a stop was made in Hainan, landing at Hoihow on the north coast. Hainan is a seldom-visited island about 180 miles long, belonging to China. Fic. 43.—A wayside shrine at Yingtak, China. These shrines are common but, like the present one, often suffer from neglect. Through the kindness of Doctor McCandliss, a missionary in charge of a hospital at Hoihow, we were able to penetrate to the interior of the island as far as Kachek where there is a branch missionary station. The journey was made by boat on the river the first day and on foot the second and third days. From Kachek a trip was made up the river into the foothills of the Five-finger Mountains. Traveling in Hainan as in many other parts of China is chiefly by chair carried by two coolies. Traveling in China is mostly by rather primitive methods. Modern steamers ply along the coast and on the larger rivers and there are a few railroads. The sampan, a small partly covered boat propelled by 42 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 oars, is common in the harbors.

One of the curious sights to one visiting China for the first time is the enormous number of graves distributed at random over the 44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 country. Thousands of little mounds are to be seen on every hand, some hemispherical and grass-covered, some more elaborate, with stones or masonry. The agriculture of China is intensive and in some ways much in advance of ours. The rice fields show usually a perfect even stand, and the amount per acre is the maximum. It represents a large amount of labor as every stalk is set out and harvested by hand. The botanical results of the trip were very satisfactory, a large and valuable collection of grasses having been made. BIOLOGICAL EXPLORATION IN THE DOMINICAN REPUBLIC In November, 1920, Dr. W. L. Abbott revisited the Dominican Republic, working in both the Samana Peninsula and the region lying between Sanchez (at the head of Samana Bay) and Puerto Plata, on the north coast. Already familiar with much of this territory, he was able to investigate a number of new and very interesting localities. Two weeks was spent at Sanchez; three weeks in the vicinity of Samana, a town on the south coast of the Samana Peninsula about 20 miles east of Sanchez, and on the mountain known as Pilon d’Aztcar ; seven weeks at several stations along the railroad connect- ing Sanchez and Puerto Plata, among which were Villa Riva, Pi- mentel, Cotuy, Mao, and Navarrete; two weeks in the easternmost portion of the peninsula, in visiting Las Cacaos, Rojo Cabo, and Cape Samana; one week on the south coast of Samana Bay in the vicinity of San Gabriel; and one week in the region of Old Heart River, in the north-central part of the peninsula. Contrasting with the remaining part of Hispaniola, the population of the Samana Peninsula is chiefly English-speaking, due to the fact that Samana was settled by a colony of Philadelphia negroes under President Boyer of Haiti in 1820-22. The region is well watered and has a luxuriant vegetation, and provisions are plentiful and rela- tively cheap. The hills extending north to the coast from Pil6n d’Azucar are covered with unbroken forests. The Yuna River forms a vast swamp, which occupies the entire region at the head of Samana Bay and extends along the railroad for a distance of 12 miles. West of this swamp region, in the vicinity of Villa Riva, Pimentel, and Cotuy, are vast stretches of grassy savannah. The soil is fertile, and the inhabitants are industrious and prosperous. Beyond this region the land, except along the streams, becomes arid and the towns, such as Guaybin, Navarrete, and Mao, are small, poorly provisioned, and lacking in enterprise.

A cave at the mouth of Naranjita River contained a quantity of Indian bones and pottery. A collection of about 4,000 plants was procured, representing 1,460 numbers. Of these about 20 per cent are ferns, one being an interest- ing new species of Anemia. The birds obtained by Doctor Abbott on this visit totaled thirty-one skins, with a few skeletons and eggs, chiefly representing species not previously collected by him. Of particular interest is a whip-poor-will Fic. 48.—Harbor of Puerto Plata, looking north from Monte Isabel de Torres. (dntrostomus), closely related to a species found in Cuba, but not hitherto recorded from Santo Domingo. On the natural grassy plains on the north side of the island he secured several specimens each of the local form of the grasshopper sparrow (Ammodramus savannarum intricatus), and of the stone-plover or thick-knee (Ocedicnemus dominicensis ), both new to the museum collections. The thick-knee belongs to a family of birds resembling overgrown plovers, and is related to them. It occurs in the West Indies only in Santo Domingo, but allied forms are found in suitable localities in Central and South America. The family is chiefly an Old World one, and for the most part tropical in distribution. The Santo Domingo species is well- known to the natives, under the name “‘ boukera,” and tame individuals NO. 15 SMITHSONIAN EXPLORATIONS, 1921 47 are often kept about the houses for the purpose of ridding the premises of insects and spiders. In addition many land shells and a considerable quantity of ethnological material were secured. Doctor Abbott left New York about the middle of December, 1921, on another expedition to the island, but thus far no information or material has been received from him. EXPERIMENTS IN HEREDITY Progress in the experiments in heredity conducted under the joint auspices of the Smithsonian and Carnegie Institutions by the writer, Dr. Paul Bartsch of the U. S. National Museum, have from time to time been published in this pamphlet and in the Year Book of the Carnegie Institution. A summary of the results attained up to 1920 was published as “ Experiments in the Breeding of Cerions”’ in 1920, volume 14 of the Department of Marine Biology of the Carnegie Institution, pp. 3-55, pls. 1-59. The reported loss of the Cerion colonies introduced into the Tortugas which were said to have been wiped out by the hurricane of September, 1919, made it necessary to revisit the Bahamas to secure additional breeding material for the heredity experiments. Accord- ingly, passage was secured at Miami on the power schooner “ Tecoma ” for Nassau, New Providence, on May 18, and there the services of the power boat “ Standard J” were secured for a trip to Andros. The desired adolescent specimens.of Cerion viaregis were obtained along King’s Road, Bastian Point, South Bight, Andros, with con- siderable difficulty because the agricultural efforts on the part of the local population have shifted to the ground that was occupied by the Cerion colonies during our 1912 visit. The colony of Cerion casablancae has met with even greater mis- fortune, for sheep and pigs have been introduced into the region occupied by this species, and the larger vegetation has been cut down in order to furnish more opportune habitat for grass culture. These new environmental conditions promise well to exterminate this colony. The necessary material for the experiments was secured with great difficulty. A trip was next made through South Bight to the western end of Andros and then back to the eastern shore through Middle Bight. On this journey many stops were made and Cerions were gathered in large numbers. The localities from which they were taken were care- fully listed so that it will be possible to go back to the same spot in 48 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 the future and gather material for comparison with that now resting in the National Museum. There were several points of interest as far as the physical features of the locality visited were concerned. In 1912 the waters of the western end of South Bight were of a creamy consistency and the land areas adjacent low flats, mud cracked, with flakes of oolitic rock. On the present visit South Bight was found to be a perfectly clear stretch of water with well-packed bottom with an abundant growth of aquatic plants, while the land adjacent gave the impres- sion of moss covered flats. The green element, however, was due to blue-green algae, which appear to serve as a binding factor. The trip was enlivened by an iguana hunt, which resulted in the securing of several of these large lizards which are now in the collec- tion of our Zoological Park. Returning to Nassau, five days were spent exploring the cays off the northwestern shore of New Providence and the adjacent main- land. Here large collections of Cerions were made, the location of each colony being carefully noted, so that these likewise may serve as a check series for comparison with future generations produced in place. On June 3 Dr. Bartsch returned to Miami and on the following day set sail for the Tortugas, stopping to examine the various plantings along the Florida keys. It was a pleasure to find that the hybrid colony on Newfound Harbor Key, around which the greatest interest centers just now, had escaped being wiped out by the hurricane. Evidently the rain preced- ing the hurricane had caused the Cerions to take to the ground, as they are wont to do for foraging purposes under such circumstances, and the dense mats of grass here had kept them from being swept away by the floods that had passed over them, a most fortunate state of affairs. A large number of dead specimens were nevertheless found, which have been placed in the National Museum for record. Incidentally, it may be stated that another almost fledged young great white heron was discovered on White Heron Key, the island that furnished the specimen that was shipped to the Zoological Park two years ago. The present specimen, which is probably a younger brother or sister of the former sending, was also transmitted by parcel post to the Zoo, where it arrived in good condition. In “ Experiments in the Breeding of Cerions,” there are given on page 46 detailed measurements of 100 specimens representing the check series of Cerion crassilabris from Balena Point, near Guanico NO. 15 SMITHSONIAN EXPLORATIONS, 1921 49 Bay, Porto Rico, which were planted on Loggerhead Key in 1915. These were figured on plates 48 to 50. On page 47 measurements were given and on plate 51 figures of 36 adult shells of the first Florida grown generation which were gathered in January, 1919. This year a much larger series of first generation material was found, and 200 of such specimens were measured. The summaries of these measurements show that no appreciable changes in measurements have taken place in the first generation of Florida grown Cerion crassilabris. The measurements in size all fall within the limits of variation, as denoted in the check series, excepting one, 1. @., a single specimen which was found among the 200 of the first Florida grown generation that had a diameter 0.2 mm. less than any in the check series. There is no doubt that one could find an indi- vidual giving such a measurement among the specimens on the native heath of this species, for the check series was not a selected one, but a hundred specimens taken at random.

The hurricane of 1919 destroyed the cages in which had been placed a specimen of each of two species, in order to determine their ability to hybridize, and to note the results of such crosses as might be observed from such selected individuals. A new set of cages was therefore prepared. Eleven groups of these cages consist of four compartments, each a cubic yard in size. The septa between compartments are double wire walls to prevent possible mating through the meshes of the fine Monel metal wire screen. In each of these cages there were placed a Hymenocallis plant, some grass and dead wood rubbish, in other words, habitat conditions which were found to be favored by Cerions at the Tortugas. Then two half-grown specimens, one of Cerion viaregis and one of Cerion incanum from Key West, were placed in each of the forty-four 50 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL, 72 compartments. These cages are securely anchored, and every pre- caution has been taken to make sure that the mollusks will be confined within them, and that no extraneous individuals can find entrance. The cages are arranged as shown in the following diagram, and a better idea of them may be formed from the photograph (fig. 50). Tic. 49.—Diagram showing arrangement of cages. Cages No. 45 and No. 46 are of the same size as those last men- tioned. In cage 45 were placed 183 young of Cerion incanum from Key West, in order to determine what percentage of these will reach maturity. In cage 46 was placed an abnormal specimen of Cerion viaregis. This had a spiral keel, which may be the result of an injury, although Doctor Bartsch was unable to discover any sign of it. With it was also placed a normal specimen of Cerion viaregis in order to determine if this character might be transmitted to offspring. In addition to these, five groups of cages were made which have the same size as the four unit cages, but they have only one partition in NO: 15 SMITHSONIAN EXPLORATIONS, 1921 51 the middle, thus making them 3 by 6 feet, and 3 feet high.

Two additional species were introduced this year on Loggerhead Key, one Cerion mayori, as above stated, and the second, Cerion incanum, as also stated above, but of this species a large colony was 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL, 72 as also placed about the water tower at the northern end of the island, in order to have additional material if it should be needed for breeding purposes in the future, While at the Tortugas a careful bird census was made, as usual.

ENTOMOLOGICAL EXPEDITION TO ALASKA In May, 1921, Dr. J. M. Aldrich, Associate Curator of Insects, U.S National Museum, was detailed to collect insects in Alaska, especially in the interior, The museum had very little material from Alaska, except from the coast region. The government railroad, extending from the southern coast north to Fairbanks, was nearing completion, and offered opportunity for travel not heretofore existing. It ap- peared also that the completion of the railroad would probably lead to an increase of population which would create greater interest in the insects of the region. NO. 15 SMITHSONIAN EXPLORATIONS, 1921 53 Doctor Aldrich left Seattle May 30. The steamship made some stops for unloading freight, enabling him to collect one day at Skag- way and one day at Valdez. The coast region is fairly familiar to tourists, with its innumerable islands, steep shore-line, snow-capped mountains and numerous glaciers (figs. 52-56). Seward was reached on Juneg. The government railroad begins at this point and close con- nections were made with a waiting train. The railroad passes over rugged mountains in the Kenai peninsula close to several large glaciers ; it then descends to sea-level at Turnagain Arm, keeping near the shore line to Anchorage. This was the first collecting point which might be considered to represent the fauna of the interior. Although Fic. 52—Cannery near Juneau, Alaska. it is on tide-water it is behind the coast range and has the dry climate characteristic of the interior. The town is on a level glacial plain, several miles wide, covered with a light forest and having a thin soil upon quite recently deposited gravel. The forest is composed of spruce, aspen, birch, alder and willow. After several days collecting here the journey northward was resumed. Steel had been laid as far as Hurricane, 285 miles from Seward. On arriving here Doctor Aldrich was furnished a horse by the Alaskan Engineering Commis- sion and rode along the right-of-way for 85 miles across Broad Pass and down the Nenana River to Healy, which was at the time the terminus of the rails laid southward from Nenana on the Tanana River. Only casual collecting was done until Healy was reached, but here it was necessary to wait several days for baggage to be brought from Hurricane by wagon. This proved to be a very good collecting 54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.. 72 point as it 1s at the mouth of the canyon on the edge of the Yukon Valley, thus combining to some extent the mountain and plain fauna. After five days here, Doctor Aldrich went north on the railroad to Nenana, collected there for only part of a day and continued the fol- lowing day on the narrow gauge line, recently acquired by the govern- ment, to Fairbanks, his destination. It had been intended to spend - Fic. 53 —North side Lynn Canal near Skagway, Alaska. Fic. 54.—Glacier on Lynn Canal, Alaska. most of the collecting time in the vicinity of Fairbanks, but the trip had taken much longer than expected, so he stayed only a week at this point. The Tanana Valley at Fairbanks is typical of the Yukon Valley in general, as far as the species of insects are concerned. Although it is within about 100 miles of the Arctic Circle, it has a fairly hot summer on account of the extremely long period of sunshine in the day. Some farms are developed and the government experiment sta- tion has been demonstrating for many years that the usual garden NOT LS SMITHSONIAN EXPLORATIONS, 1921 5 on vegetables of the northern states as well as some cereals can be grown.

As each wagon turned back on unloading, and only a few were in use at the time, considerable delay was encountered in getting baggage moved from Healy to NO. I5 SMITHSONIAN EXPLORATIONS, IQ2I 59 Hurricane. This delay could have been used to good advantage for collecting except for the fact that the weather became cloudy and windy and very unfavorable. Doctor Aldrich, after several days delay, went on to Anchorage and spent a few more days collecting there while awaiting his baggage. Here the weather was again favor- able so that the result was very good. Resuming his journey Doctor Aldrich went to Seward with the intention of spending at least ten days in getting a collection of the insects of the humid coast region. The weather, however, gradually became more rainy, greatly limiting the result and finally making it expedient to take the boat from Seward about a week after arrival. Fic. 63.—Middle fork of Chulitna, a little south of Broad Pass. Corduroy bridge of the Alaskan Engineering Commission. The expedition resulted in the accession of about 10,000 specimens of Alaska insects, nearly all from the interior region. As far as they have been studied up to the present time they indicate three somewhat distinct faunal regions in the territory covered. First, the maritime fauna consisting of the insects living upon the seashore and depending upon the ocean for necessary conditions of existence. Insects of this group extend down the coast, in many cases as far as the State of Washington and some even so far as San Francisco; while it is presumed that they would also be found more or less in the Asiatic side of Bering Sea. The second element is that of the humid mountain region along the coast; a considerable part of this fauna extends to Puget Sound, 60 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. ee. eh Fic. 64.—Contractors’ cabins on the line of the government railroad near Broad Pass, Alaska.

The third element of the Alaska fauna, as far as observed, is that of the dry interior and especially of the Yukon Valley, which has many elements in common with Northern Minnesota, Wisconsin and Michigan, Ontario, the Adirondack Mountains of New York and the White Mountains of New Hampshire. Many of the insects of this group also occur in the Rocky Mountains of Colorado and no doubt further exploration will show that they occur in other mountains of the western United States. Those which represent a more northern Fic. 66.—Town of Healy in the lignite belt on the Nenana River, Alaska. range also reappear in Labrador collections, and presumably extend across North America although we have no collections from inter- mediate points. This element contains many species known from Finland and the Scandinavian Peninsula in Europe, presumably ex- tending in their distribution across Russia and Siberia. In most orders of insects Alaska has a comparatively large fauna. There are very numerous species of the two-winged flies, or Diptera ; and from Doctor Aldrich’s long experience with this group he natur- ally paid especial attention to collecting in this order. Bumble bees and wasps are conspicuous insects everywhere on flowers; and in the absence of darkness bumble bees were observed to work as late as 10.30 at night in Fairbanks. Grasshoppers were strikingly scarce, only two species being found and in all but half a dozen specimens. 5 62 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 72 Mosquitoes in the interior are exceedingly abundant, as is well known. Especial attention was given to them in collecting, and two species previously undescribed were among the material brought back. It appears, however, that the most troublesome species are the same ones which occur in somewhat less numbers in the Pacific northwest in occasional favorable localities. Horse flies are very numerous in the region at Fairbanks where they are commonly called moose flies since the moose is more common than the horse. ni Pet *,
