INTRODUCTION AND ACKNOWLEDGMENTS The field work on which this paper is based was carried on as time would permit while the writer had charge of the Lummi Indians in 1905 and the Quillayute and Hoh Indians in 1905 to 1909. Western Washington and adjacent British territory, as here considered, embrace the Olympic Peninsula, the shores and islands of Puget Sound and Georgian Bay and that part of British Columbia lying northward from the International Boundary Line to the Fraser valley and delta. In general it is a most difficult region in which to do research work of any kind; for away from the trails and roads the fallen timber, underbrush and ferns make the forest such a jungle in most places. For convenience, the archeology of the region will be con- sidered under three general headings, viz.: The Archzology of the Olympic Peninsula, The Archeology of the Lummi- Nooksack country, and The Archzological material in ad- jacent British territory. In submitting this paper the writer wishes to thank Messrs. Barton W. Evermann and FE. W. Gifford of the California Academy of Sciences, Harlen I. Smith of the Canadian Geo- logical Survey, F. W. Hodge of the Bureau of American Ethnology and Charles W. Smith, Assistant Librarian of the University of Washington, for their kind aid in helping him with the bibliography.

As has been previously mentioned about the region in gen- eral, the Olympic peninsula is a very difficult country in which to do research work. There are but three wagon roads in the entire area west of the Olympics. One of these roads, aggre- gating some 50 miles in total length, connects Port Angeles with Lake Crescent and Port Crescent and the latter again 4 CALIFORNIA ACADEMY OF SCIENCES (Proc. 4TH Ser. with Lake Crescent. The second road extends from East Clallam, on the Strait of Juan de Fuca, west to LaPush, on the Pacific front, a distance of about 50 miles. The third road connects the above roads along the line of the Soleduck River. Trails also extend from West Clallam to Ozette Lake and the Dicky Lake country, and from the latter to Quil- layute Prairie. Another trail connects Forks with the Hoh country. A few short trails also branch off of the main trails here and there. These afford all the means of gaining access to the interior, except by canoe on the various streams. This peninsula covers an area of about 8000 square miles, or an area about the size of Connecticut, Rhode Island and Delaware combined. It extends approximately 100 miles in a north and south direction and 80 miles in an east and west line. It is triangular in shape with its hypotenuse side facing the Pacific. It is bounded on the north by the Strait of Juan de Fuca, on the east by Puget Sound, on the south by Che- halis River and Gray’s Harbor, and on the west by the Pacific Ocean. Cape Flattery is at the northwest corner and Port Townsend at the northeast, and the snow-capped Olym- pics occupy the central area. The region consists generally of a benched area along the coast from which the foothills gradually ascend toward Mount Olympus, 8150 feet in height, and watershed between the Strait of Fuca and the Pacific, a high ridge which extends from the central mountain area to Cape Flattery. Port Townsend, Port Angeles, Neah Bay, and Cape Flattery on the strait, and Quillayute (LaPush) and Gray’s Harbor on the Pacific, are its most commonly heard of places. The region was first discovered by the Spaniards. In 1775 Bruno Heceta, a Spanish captain, landed on the coast a little south of the mouth of the Hoh River, planted the cross and took formal possession of the country for Spain. Then at the foot of the cross he had thus set up he buried a bottle sealed with wax, in which was the written record of his work and the statement that he took possession of the land for Spain. While he was thus in the official act of taking pos- session of the country, the Indians visited his ship, the “Sonora,” under the lee of Destruction Island, in charge of Heceta’s companion, Bodega Y Quadra. The Indians came Vor. VII] REAGAN—ARCHAOLOGICAL NOTES 5 in their canoes, held up bits of copper and iron, and with friendly signs sought to trade for more of the metals precious to them. Believing that everything was well, Quadra sent seven men ashore to trade with the Indians for wood and water. No sooner had they landed than 300 Indians rushed from ambush, killed the sailors, and tore the boat to pieces for the metal fastenings. Quadra was furious and wished to land 30 men to obtain revenge, but Heceta overruled him and sailed away, naming the island “Isla de Dolores,” Isle of Sorrows. Later, in July, 1787, Captain Barclay, an English explorer, had a similar experience with these same Indians, in which he lost six men. He named the river of Hoh “De- struction River’ as a result of this encounter, but late geographers have restored the Indian name “Hoh” to the river, but retain the name “Destruction” for the island that Quadra named “Isla de Dolores.” On August 1, 1790, Alferez Quimper, having been sent to explore the Strait of Juan de Fuca by the Spanish Captain Elisa, discovered Neah Bay and Bahada Point, two miles farther east. The former he named Bahia de Nunez Gaona. At about the same time the Spanish Captain Don Francisco Elisa discovered Port Angeles. He had been tossed about for many weary days by storms and furious waves when sud- denly he came upon a long, snake-like spit extending far out into the strait, curving so as to protect a large bay on its western side. In this bay he took refuge; and in consequence of the safe and perfect harbor thus formed, he named it Port Angeles—“The Port of the Angels.” In May, 1792, Lieut. Salvador Fidalgo established a military post at Neah Bay, with necessary buildings and fortifications, and remained there until September. The bricks of the old fort—bricks imported from Mexico on the “‘Princessa,” can be found in the earth banks there to-day. Here the Spaniards came in contact with the British, under Vancouver. A conference was called, and Quadra failed to agree with the latter. Then the two commissioners agreed to send to their home governments for further instructions, as a result of which the Spaniards were compelled to abandon the country. While Vancouver was maneuvering with Quadra for the possession of the North Pacific, our own Captain Gray was 6 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. making his famous trip up the coast, staying the winter of 1791-’92 at the harbor that bears his name. As a result of this trip, and that of Lewis and Clark to the Columbia later, the country was jointly occupied by the British and the United States till the treaty of 1846 gave the Oregon terri- tory to the United States. And later, in 1855-59, Governor Stevens's treaties settled the Indian troubles. The explorers found a tribe of short, heavy set Indians occupying the valley of each stream that flowed out into the ocean or strait; the village of the tribe being at the mouth of the respective stream. In addition, the Makahs occupied the Cape Flattery section of the peninsula and the Chemakums the Port Townsend division. These lived principally by fishing, though they also hunted. They represented different linguistic stocks and were continually at war with each other. The wars were carried on principally for the purpose of cap- turing slaves. Besides the slaves, who were almost always cruelly treated, the people of each tribe were divided into chieftain stock and the base people. The former owned the land and received the greater part of the benefits of the hunt- ing expeditions and of the fish and whale catches. In fact the base people were considered only a little better than slaves. The peninsula divides itself into several archzological fields, namely: The Quillayute region, the Hoh region, the Ozette-Makah region, and the Strait of Fuca and Sound region. The archeology of each of these divisions will be considered in the order given. THE QUILLAYUTE REGION The Quillayute region centers about the Indian village of LaPush, Washington, at the mouth of Quillayute River on the western coast of the Olympic peninsula some 36 miles down the coast from Cape Flattery at the entrance of the Strait of Juan de Fuca. It includes the territory drained by Quillayute River and its tributaries and also extends up and down the coast for several miles on each side of the Indian village. The archeological remains found in this region are middens, burial mounds, a cave-burial place near James Island, and over-mounds. Vou.

OLD MOUTH OF QUILLAYUTE RIVER LaPush and vicinity, Washington be} CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. The middens are of three classes, based upon age: ancient, old, and recent. The recent middens were made since the Astoria~-Hudson Bay fur trading began, as is attested by the Hudson Bay Company’s beads being intermingled with the middens. These middens were observed on James Island (the ancient home of the Quillayute Indians just off the shore from the present village), on both the Lagoon and Pacific water fronts at LaPush, and on and flanking Pacific Street ridge in the vil- lage itself. In all, they veneer an area of about 20 acres, some places detected only by the scattered “blue beads”. The middens themselves are like those which will be described later, except they are less thick and are practically unde- cayed. The middens here designated “old”, underlie the recent at LaPush and on James Island; scattered patches also occur at several other places. Their greatest thickness, however, is to be found on James Island, where the Quillayutes were mak- ing their last stand against the Makahs to the northwest when the white man came on the scene. But how much of the middens on this island are “old”, how much recent, and how much ancient, can not now be determined. The area which they cover has been used as a garden for many years; and, consequently, they have been much disturbed. Their original thickness of five to 15 feet, however, indicates that they were many years in accumulating. The midden material is here much decayed, but to a less degree than that of the next series described below. The ancient middens underlie and are found to be inter- mixed with the more recent middens on James Island. They are also found on the Pacific water-front, also flanking and capping Pacific Street ridge at LaPush. A large patch of them also occurs near Jackson Creek about six miles south of the present village, and another, beyond the “point” on the coast about two miles northwest of the mouth of Quillayute River. Combined, they cover many acres in extent, but their original areas can not now be determined. The encroaching ocean has now removed practically the whole area on the Pacific front at LaPush; it removed a space along the whole village front 200 feet wide from 1904 to 1907. It has re- Vor. VIT] REAGAN—ARCHZOLOGICAL NOTES 9 duced the Jackson Creek area to a small wedge-shaped piece of land, and each high tide carries more of it away. The area above the “Point” also breasts each high tide. Further- more, Quillayute River in the ages gone by has removed the northwest end of Pacific Street ridge and since 1912 has returned in its course and is again undermining the north end of this ridge. These facts, together with the fact that the coast in this region is sinking, show conclusively that these midden-areas were much larger originally than now. Middens of this age are also found far inland, at Beaver Prairie, Forks Prairie, Quillayute Prairie, and at various camping places along the Quillayute River and its tributaries; more recent middens are also found at each of these places. These ancient middens, as of the other classes previously mentioned, are composed of decaying remains of marine shells, intermingled with enormous quantities of ashes, cal- cined and fractured rocks and other refuse material, all showing evidence of extreme age. Their age is further at- tested by the fact that huge trees, hundreds of years old, are growing on them. A list of the marine and other species found in these mid- dens, together with drawings of similar sea species are to be found at the close of this section. The relics found in the middens are few in number, and but few of them are of stone. In the valley of the Quillayute River and southward along the coast for many miles, there are no hard slates, schists, or volcanic rock of any sort; and only to the northward in the Makah lands are there even granite boulders in any great number. Consequently, the Quillayutes had no material of which to make stone imple- ments, except the agates of the beach. These they made into arrow heads but in no great numbers. Arrowheads when found, have usually been of the rough paleolithic type. The finding of implements of jade-like rock and basaltic glass or thin slate is indicative of an attack made on the village by the tribes to the north, where these rocks are plentiful. The people of those old times had no earthen pottery; basketry was used plentifully, and cups, dishes, spoons, and plates were made of wood. Fish knives were usually made of clam or mussel shells; the adzes, axes, skinning knives, scrapers, and 10 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. chisels were made of elk horn. Few relics are found in these ancient middens for the reason that the wood, shells, and bones used in making implements and utensils were so perish- able. Those found are mostly barbed and grooved bone spear and arrow points, bone skinning knives and scrapers, whale rib daggers, bone needles, and mussel shell knives. The burial mounds, so far as the writer has been able to locate them, are few in number. In the old days and until quite recently, the Quillayutes “buried” their dead mostly in canoes suspended among the leafy branches of the alder trees that border the various streams. They also cremated the dead. Furthermore the encroaching sea might possibly have obliterated some ancient graveyard, as it is washing away the graveyard of last century there now. Consequently, the few- ness of the burial mounds. The mounds are composed of clay, rock, clay and sand mixed, or of boulders only. The mounds of each type are usually several feet in height and many feet in diameter. Some of them approach an ellipse in shape; others, the form of a parallelogram. The material of each mound seems to have been heaped up over the corpse, which seems to have been laid on the top of the ground. The boulder heaps often contain fragments of cedar which would make one think that a crib of cedar might have been made over the corpse and then over this the boulders were piled, in the same manner that the Apaches of Fort Apache, Arizona, bury their dead on the east bank of White River to-day. Ashes in some of them seem to be against this theory, unless the body was cremated before the covering-over was done. Some of the other mounds have only ashes in them, which seems to indi- cate that the body was cremated before interment. The re- maining mounds have almost wholly decomposed bones, often only traces of bones, in them. Some of the mounds also have a layer of ashes a foot or so above the corpse. This would seem to indicate that the belongings of the deceased were burned on the grave after the corpse had been covered over with a layer of earth. In all the various classes of mounds examined, no relics have been found. It therefore seems that they were made by Vo. VII REAGAN—ARCHZOLOGICAL NOTES 11 the same race of people that now occupy the region. On ac- count of a lack of data, however, this is inconclusive. Many “oven-mounds” are found. In outward appearance they resemble the burial mounds above described. Within, however, are the charred remains of fruits or sea species that have been over-baked. That these are oven mounds, there is no doubt, as the Quillayutes bake clams, wild fruits, and “la camas” (Kammas, Scilla fraseri) in the same sort of oven to this day. A pit is dug in which a fire is built. On the fuel cobbles are piled, which, when heated to a red heat, are covered over with wet leaves, brush, or grass. On this the fruit or sea species are piled and over all wet grass is spread to a thickness of, say, seven inches. Then over all clay, earth or sand is heaped. Just before completing the covering over with the earth, a quantity of water is poured on the cooking product and then when the covering is completed a small hole is left through the dirt layer for the escape of steam. The cooking process is then let have its course for about 24 hours, when all is removed, or a hole dug through the top of it, and the cooked product removed. The earth- mound is left and the shifting sand fills up the hole from which the baked articles have been taken. The mound is then complete. The cave-burial place is in a niche on the east side of a little islet a few hundred feet north of James Island. In the long ago this cave was more extensive than now; the en- croaching sea will soon obliterate it entirely. How large it was originally, of course, can not now be determined. In it, under and intermingled with several feet of loose rock and boulders, were the bones of the dead, which were now and then uncovered by the pounding waves. [For many years every white man who has come along has carried away some of the bones. Whether any of them have been placed in some museum is unknown to the writer. It is not likely that any of the bones are now left, as the waves have been sweeping the entire cave at high tide since 1908. Besides the bones, this cave has yielded some stone implements: a stone adz, several arrow points and a stone pipe were dug out of the debris in 1907. The writer was told that it yielded a con- siderable quantity of these implements in the last 35 years. 12 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. On inquiring of the Indians about this cave, the old people say that it was in it that their people threw their enemies killed in making attacks upon James Island. More- over, Doctor Klekabuck told the writer that it was in this cave that he and the other Quillayutes threw the Makahs, slain in an attack upon James Island some time in about the sixties of last century. That this cave was the burial place of slaugh- tered enemies there seems to be no doubt. The stone imple- ments found are made from stone that is not found in the region and must have been brought there in implement form by the person with whom it was interred. Furthermore, one would conclude that the boulders and cobbles were hurled on the dead by the spiteful Quillayutes on their coming and going past the cave-entrance in the days following the un- successful raids. As a concluding remark on the archeology of this section, it seems, from the evidence at hand, that the archzeological remains were made by the same race that now occupies the region. ‘This opinion is also strengthened by the fact that the Quillayutes have no tradition of having migrated from any other place. They firmly assert that they have always lived there. But the finding of complete skulls in the ancient mid- dens and burial mounds would be conclusive.’ 1Below are some Quillayute myths that might be of interest to the readers. A Thunder-Bird Myth. The Indians believe that in time of stormy weather a bird of monstrous size soars through the heavens and by the opening and shutting of his eyes it produces the lightning and by the flapping of its wings it produces the thunder and the mighty winds. This bird, they say, has its nest in a dark hole under the glacier at the foot of the Olympic glacial field and that its moving about in its home there produces the ‘‘thunder-noise”’ there. Myth Concerning the Origin of Crescent Lake. The Quillayute myth about the origin of Crescent Lake is as follows: ‘Once, in the valley which the lake now occupies, our people and the Clallams were having a big battle. For two days the people killed each other. Then Mount Stormking be- came enraged. You know the mountain that overlooks. the north end of the lake from the east. Well, Mount Stormking got angry (all things on earth were living beings then) and he took a great piece of rock from his crest and hurled it down into the valley, killing all who were fighting and at the same time damming the stream with the great rock, so that it has been as it is now ever since, and no Indian has gone near the place since that day.’’ (This myth causes the question to arise: Has there been volcanic activity in the region since the Indian occupation? Undoubtedly it was a volcanic region in Eocene times, but as yet evidence of later volcanic activity is wanting.) The Thunder-Bird and the Myth About the Origin of Beaver Prairie, Clallam County, Washington. (Police Hobucket). “The thunder-bird lives in the heavens. He produces the lightning by his rapid flight through the air, the ‘big noise’ by the flapping of his wings. He feeds on the whale. Once he got a big whale in his talons and carried him to Beaver Prairie and ate him there. The whale fought terribly hard before he was killed. So terrible was the fight that in the struggle the combatants killed all the timber in the vicinity and Bellce up the trees by the roots. And no trees have ever grown on the site to this ay. Vou. VIT) REAGAN—ARCHZOLOGICAL NOTES 13 The Thunder-Bird, the Unsuccessful Battle with the Mimlos-Whale, and the Origin of the Prairies of the Olympic Peninsula, (Police Luke Hobucket). “At the time of the great flood, the thunder-bird, the representative of good, fought the Mimlos-whalc, the representative of evil. The great battle lasted a long time. For a long time the battle seemed undecided. The powerful bird could not whip the beast in the water. Time and again it seized it in its talons and tried to fly with it to its nest in the mountains; but the powerful ocean monster would get away from it. Each time that it seized it there was a terrible battle, and the ‘big noise’ caused by the bird’s flapping its wings (the thunder) shook the very mountains. The places where these fights occurred were stripped of their timber, the trees being torn out by their roots. A curse was brought upon them, and to this day no trees grow upon them. They are the prairies of the country. At last the whale escaped to the deep ocean, and the thunder-bird gave up the fight. That is why the Mimlos-whale or killer-whale still lives in the ocean to-day.” The Thunder-Bird and the Origin of the Glacial-Boulder-Train Across Beaver Prairie, (Police Luke Hobucket). ‘““A man was living at Wo-lot (Beaver Prairie). He was an elk hunter. He went off hunting very early one morning, but soon came back, saying that he had seen a very big bird sitting in a tree just a little way above the ground. ‘The bird was the thunder-bird. The man took one feather from thunderer’s wing. It was just as long as a canoe paddle. He bent the feather and put it in his quiver and brought it home with him. After he had shown the feather to the people, he said: ‘I also saw a very, very big whale on the prairie. It had been carried there by the bird. The bird was resting because it had such a big load.’ “The man sent word to all the Quillayute people at the mouth of the river to come up and cut up the whale, because it was so large that the bird could not carry it further. All the beach and river Indians, three to six in each whaling canoe, came at once to the prairie to cut up the whale. On reaching there they found the huge whale lying dead in the lower part of the prairie, as had been reported. They immediately commenced measuring off the parts they wanted; one family took the saddle, another the head, and so on. By evening they had it all cut up. They piled up the block-like sections of blubber all over the ground. Night came on; and the clouds overhead became black. The thunder-bird had been robbed of his prey and now he was returning with vengeance in his wings. It commenced to lightning and shower a little, not so much at first. Then it hailed large hail, hail larger than your fist. The hail killed and mangled all the people on the prairie. The Indians had cooked and eaten whale meat that evening; and it was all right, it was good to eat. But after the storm both meat and blubber were turned to stone, as were the people also. And to-day, in great blocks of rocks, they form the ridge from one end of the prairie to the other. One may even see the ribs of the whale’s carcass and its massive head.” An Indian Myth of How the Headlands and Promontories of the Washington Coast Were Formed. (Elon Mason). “Tt was long ago, when people were animals and animals were people. Kwatte was then still living on earth. He had his house on the beach near here; but he got hardly anything to eat, for the wolves of the region prowled the coast, caught the salmon, ate all the berries, and devoured all the animals of the woods, and gulped down all the fish eggs that floated ashore. What was Kwatte to do? One day the chief of the wolves came along up the coast. He came to Kwatte’s house. Kwatte pretended to be sick. The wolf came in, He made himself at home. Kwatte let him stay. That night he made his bed at Kwatte’s house beside Kwatte’s fire. Soon he was sound asleep. When he had been asleep for a considerable time he began to snore. He snored loud. This was Kwatte’s opportunity. He would now get even with the wolves; and would also have some meat to eat. He got his knife, looked at it to see if it was good and sharp, then, finding it in good shape, he went to the mat on which the wolf was sleeping and severed his head with one blow. He then skinned the car- cass and hung the skin up above the fireplace in his house to dry. Then he stored the meat safely under his bed. Then he went to sleep. “The next morning, bright and early, a wolf came tracking his chief up the beach. He tracked him to Kwatte’s house. He entered the house. Said he to Kwatte, ‘Did you see Chief Wolf?’ Kwatte answered, ‘No; I am sick; I have not been out of my house: I have not seen him.’ ‘But he came into your house. We tracked him here,’ exclaimed the wolf. While wolf and Kwatte were talking, the wolf’s slave, the blue jay, had gone over to Kwatte’s fire to warm himself. As he was spreading his hands out before the fire, a drop of something fell on the upper surface of one of his hands. At once he perceived that it was a kind of oil. He smelled it. At once he recognized it to have the same smell as the smell of his master. He said nothing, but went out of the room. The oil had dropped from the skin that was drying. As soon as he was out in the yard the blue jay told all the wolves what he had discovered; many wolves had now followed the track to Kwatte’s house. The blue jay was cry- ing, mourning the death of his master. The wolves all rushed into the house, Kwatte had anticipated trouble and had hung a basket of combs near the door. As the wolves entered, he made a quick move, seized the basket of combs, and before the wolves could lay hands on him he sallied forth out the door past them and into the woods near by and then down the beach. The whole pack of wolves now followed him in hot pursuit. Time and again they nearly overtook him. But as they were just in the act of seizing him he would take a comb out of the basket and drop it down on the beach 14 CALIFORNIA ACADEMY OF SCIENCES (Proc. 4TH Ser. in front of them, edge up, thus forming a point of land projecting from the main- land across the beach into the surging waves. The wolves, of course, were compelled to climb over the promontories thus formed. Many of them they climbed over; but finally gave up the chase. But Kwatte kept on running till he had stood up all his combs on the beach. These combs are the headlands and promontories of the re- ion now. " “A long time afterwards he came back, dressed in the dry wolf hide, and went to the house of the wolves and danced and sang before them, thus clad. And they dared not touch him, because of the wolf-skin dress he wore.” List of fish, animal and plant remains found in the middens at LaPush, Washington, and vicinity with drawings of simi- lar living sea-shell species of the same locality, given on plates numbered 1-4, as indicated.

VIT] WARING—STRATIGRAPHIC AND FAUNAL RELATIONS 43 INTRODUCTION General Statement.—Vhe Chico and most of the Eocene ma- terial on which this paper is based, was collected by a Stanford geologic party, of which the writer was a member, during the summer of 1910. Much of the Tejon material was kindly fur- nished by Messrs. R. B. Moran and J. O. Lewis. Since the original manuscript of this report was prepared the writer has had opportunity to visit more territory in the state where the Cretaceous and Eocene are represented. The re- port has been thoroughly revised and all late reports on the subject consulted and incorporated. Acknowledgments.—Thanks are especially due to Dr. J. P. Smith under whose direction this paper was prepared, and to Harold Hannibal for assistance in determination of the faunas. Dr. Roy E. Dickerson has kindly assisted in the revision. Messrs. R. B. Moran and J. O. Lewis have made valuable con- tributions of fossils, without which the relations of the Mar- tinez to the Tejon could not have been embodied in this report. Historical Review.—Since the first attempt, made by Dr. T. W. Stanton,’ to clear up the relations of the Cretaceous and Eocene on the Pacifte Coast, much has been done towards dif- ferentiating them. The Chico-Tejon beds which were thought by early geologists to be a faunal and stratigraphic unit, have been shown by Dr. Roy E. Dickerson’ to consist of three distinct units, separable both faunally and stratigraph- ically. The Martinez formation north of Mt. Diablo is sep- arated from both the Chico and Tejon formations by uncon- formities, and the faunas show strikingly the interruption in sedimentation. Evidence confirms the belief, however, that this unconformity does not exist wherever these formations oc- cur in California. In those parts of central California* where Chico and Eocene strata occur, with the Martinez lacking, the Tejon rests unconformably on the Chico. 1 Stanton, T.

Diller, Stanton, Anderson, Smith, Crandall, Packard, and others. The Cretaceous record of Cali- fornia has been kept exclusively by the Pacific, so naturally we may expect to find faunas from southern California closely re- lated to faunal assemblages from northern California, Vancou- ver Island, Alaska, Japan and India. Comparing southern faunas with those from these regions, one is impressed with the large number of genera which occur elsewhere around the North Pacific. The Chico of California is confined primarily to the Coast Ranges, with smaller areas on the northeastern border of the Great Valley from which it was originally de- scribed. These deposits are not confined to the flanks of the Coast Ranges, but are often found as remnants resting uncon- formably on the older metamorphosed sediments. Most of our Eocene deposits are closely associated with the Chico and are often apparently conformable with it, although an unconformity usually exists. The area covered by the Chico rocks in Cali- fornia is not great, but its stratigraphic limits have been very difficult to determine, where it is associated directly with the Horsetown below or with the Martinez above. When either of these formations is absent a rather distinct unconformity is apparent. The Chico epoch, wherever its record has been ob- served in California, has been one of rapid sedimentation. Especially is this true in the lower Chico which is made up almost entirely of sandstones, and its fauna are those adapted to littoral conditions. The Martinez.—North of Mt. Diablo, “the Martinez forma- tion is represented areally by a strip averaging a quarter of a mile wide, which extends from lower Oil Creek westward for four miles. Its west end is terminated by a cross fault, while its eastern end is cut off by the Tejon conglomerate.’’* The Martinez has been found in southern California only in the Calabasas sheet, east of Santa Ana® and east of Los Angeles in the Rock Creek quadrangle. The formation in the Calabasas Ate R. E., Univ. of Calif. Publ. Bull. Dept. Geol., vol. 6, p. 175, 1910-11. 5 Martinez and Tejon are reported on the west flank of the Santa Ana mountains by the class in paleontology from the University of California in 1913. Vor.

The Tejon consists of 200 feet of heavy bedded conglomer- ate, 200 to 300 feet of shale, and 1700 to 1800 feet of shales, fine sands and conglomerates, towards the base of which is the oil bearing horizon. The fossils described were taken from 1000 to 1500 feet from the top of the upper beds. From the Sespe-Eocene contact to 300 feet below the contact the following species were found at Locality 8: Pinna lewisi, new species; Dentalium coopert Gabb, Natica hannibali Dickerson, and Turritella uvasana Conrad. Tejon.—The formation mapped as Tejon in the Camulos quadrangle consists of those sedimentary strata formerly mapped as Topa-Topa,”” and identical beds in Simi Valley. The lithologic descriptions, and lists of fossils have been.care- fully considered and they can _be, in part, correlated with the Tejon of the type locality.** Since the Topa-Topa sediments form a conformable series with a distinct fauna which is iden- tical with part of the Tejon formation, it would be less confus- ing to future correlations if we drop Eldridge’s local name. It has served its purpose as a preliminary horizon name. Tejon in Simi Valley.—These sedimentaries are folded along a NESW. axis. Inv Simi Valley) they overlie ‘the upper shales of the Martinez and dip to the NW. at an angle of about 35 degrees. They are exposed in the hills NE. and SW. of Santa Susana’® and consist of over 2000 feet of strata. This thickness consists of about 200 feet of conglomerate, 200 feet of oil bearing shales, and 1800 feet of shale, sandstone, and conglomerate. This upper shale member contains fossil plants and is probably a fresh water phase of sedimentation. The thickness of Tejon sediments in this entire region is very great as compared with the 1850-foot section in the San Joaquin Valley region where erosion took place through considerable of the Martinez and lower Tejon time. Tejon north of Santa Clara River Valley.—North of Fill- more, Eldridge” lists fossils from beds exposed in Sespe Gorge, north of Tar Creek. He assigned these fossils to the Sespe (Eocene) and stated that they might be from beds below his 17 Bulletin U. S. Geol. Survey, No. 309, p. 5, 1907. 8 Geol.

However, he recognized the fauna as Eocene. ‘These are all typical Tejon species and evidently came from Tejon strata underlying the Sespe, for it is known that Tejon is ex- posed in the immediate vicinity. Southwest of Sespe Gorge near the Silver Thread oil field the Tejon is exposed as a southerly overturned anticline with NE.-SW. axis. In no published reports has the name Topa-Topa been applied to strata older than Tejon, and it is improbable that the Martinez will be found exposed farther to the northwest in the region of less intense folding. RELATIONS OF THE CRETACEOUS AND EOCENE FORMATIONS SouTH OF THE SANTA Monica MOUNTAINS South of the Santa Monica Mountains, the structure is even more complicated. Two large faults cut across Topanga Can- yon (see fig. 3, p. 51), and a large wedge-shaped block of Chico sediments is exposed. These consist of about 6000 feet of sedi- ments, the lower 1500 feet being largely sandstone with dark micaceous shales interbedded. Above are about 4000 feet of well consolidated conglomerates with interbedded sandstones and shales, the pebbles of which vary from one inch to four or five inches in diameter. The upper division consists of 1200 feet of shale and light colored, fine-grained, medium bedded sandstone. The sandstones are characterized by an abundance of biotite. The lower sandstones are fossiliferous in places. The only fossil found in the upper shales was Scutella (?) species. Scattered over the surface of this Cretaceous area are remnants of the Martinez strata, in places bearing fossils. Some of the boulders bearing these Martinez fossils have found their way into the stream channels. The Martinez fos- sils found in this area at Locality 5 are the following: Fasciolaria mucronata (Gabb), fRetipirula crassitesta (Gabb), Pseudoliva howardi (Dickerson), Polynices horniu (Gabb), Turritella martinezensis Gabb, Turritella pachecoensis Stanton. A strip a mile and a half wide to the southwest, bordering the coast, is brought into contact with the Chico by faulting. This formation is terminated by faulting east of Malibu Canyon. Faulting has complicated the structure to such an 54 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. extent that Cretaceous and Martinez fossils are found very close to those of Vaqueros age in a point on the coast. No attempt will here be made to differentiate them positively, but generally the formations are shown in their proper relation on the map, page 51, fig. 3. EocENE CORRELATION Venericardia planicosta Lamarck and V. planicosta regia” Conrad, range from lower Chickasawan, Lignitic or Wilcox, into the upper Chickasawan, Lignitic or Wilcox. This range is practically that of the Aquia formation. These species com- pare most closely with V’. planicosta hornii (Gabb) of the lower Tejon of California. V. planicosta var. 5 Harris”, V. marylandica Harris”, V. potapacoensis Harris™*, and V. planicosta Harris (not Lam- arck?) range from upper Chickasawan into the Claiborne. This range is the range of Harris’ Nanjemoy in Maryland and corresponds to that of ”. planicosta ionensis Waring” of the Umpqua or Arago formation in Washington, and the lone at Merced Falls, California. V. planicosta venturensis of the upper Martinez of the Camulos quadrangle is of an entirely different horizon and represents sediments of Midway age and older. This species agrees more closely with V. planicosta ‘Lamarck of Harris,?’ which seems deserving at least of subspecific rank. V. planicosta Harris** seems to represent the typical V. plani- costa of Lamarck of which the writer has access to several specimens from the Paris basin. It seems then that the typical V. planicosta is confined to a horizon which is to be correlated with the Lignitic of the Gulf States. The turritellas especially show the close relationship, and both the pelecypods and gas- teropods are very close to many Midway species. It will be seen, then, that the Tejon is higher than Dall*® placed it in 1896. It surely is to be correlated with the lower BP mcs Geol: Surv.

Chickasawan. The Ione formation is probably to be correlated with the upper Chickasawan, while the upper Arago probably runs as high as into the lower Claiborne. The table, page 55, shows the various venericardias of the Eocene, and their horizons correlated with one another. CONCLUSIONS The Chico strata of the Calabasas sheet are lithologically like those of the northern Coast Ranges, and contain a similar fauna. They consist of a lower sandstone and an upper shale member, both of upper Chico age. The Eocene lies unconformably on the Chico, and is repre- sented by two distinct formations. The Martinez, or lower Eocene, is faunally very distinct from the Tejon, or middle Eocene, and apparently conformable with it. A slight uncon- formity may exist. The Martinez is, in part at least, to be correlated with the Midway of the Gulf States, while the Tejon is more nearly to be correlated with the lower Chickasawan, or lower Lignitic, of the Gulf and Atlantic States.

Since this manuscript was prepared, Lima haseltinei Dicker- son, has been described,*® from the Martinez in the Mount Diablo quadrangle, with the statement that it is the same species as a Lima found by the Stanford Geol. Survey in the Martinez just north of the Calabasas quadrangle. The writer does not believe that the two species are the same. In compar- ing them, conclusions must necessarily be drawn from a com- parison of the two specimens themselves and from the figures and descriptions of them. The figure of Lima haseltinei Dick- erson (plate 8, fig. 2), is not even similar to Lima perrint War- ing, and one can judge little better by comparison of the speci- mens themselves. The small specimen (pl. 9, fig. 11) included by Dickerson in his description of L. haseltinei could not pos- sibly be L. perrini, and the writer has doubts as to its belonging even to the same genus. In his description, however, Dr. Dickerson has combined the characteristics of his two speci- mens in a description of his type, the larger specimen, although he apparently questions the identity of the two specimens him- self. In his description, Lima haseltinei is described as having square ribs. Lima perrini has distinctly fine linear ribs, is pro- portionately higher than long, and one-third larger, besides having a very different hinge-line. Since the type specimen of Lima perrini is a right valve and the type specimen of Lima haseltinei a left valve, no positive determination can be made at this time. When more specimens are found at both localities, it will either prove or disprove the identity of the two; but until then it is best to consider them as distinct species.

Locality 8, L. S. J. U. Pal. Coll. Only sandstone casts of this species were found. This subspecies, for so long called V. planicosta Lam. by Pacific Coast geologists, certainly deserves at least subspecific rank. In our California Eocene there are, no doubt, three dis- tinct forms of Venericardia. The young, pl. 11, fig. 5, shows the characteristic knotted ribs of the young stages of V. plani- costa hornii. The ribs are fine, hair-like, with deep interspaces ; they are mounted by rows of tubercles until they attain a height of about 14 mm., after which they are abruptly rounded. This subspecies is distinguished chiefly by the flaring mar- gins, broad, flat ribs, linear interspaces, and by the greater length as compared with the height. It grows to be much 96 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. larger than any specimens of V. planicosta venturensis that have been found. It has been found only in the Tejon forma- tion of the Pacific Coast and is a characteristic horizon marker. Introduced here for comparison are figures of V. planicosta ionensis,* pl. 11, figs. 1 and 2. This species is from the Umpqua beds, a higher horizon than that of V. planicosta hornu, and represents a later development in the evolutionary series. The young form exhibits the same type of ribs as V. planicosta hornii and at a height of about 10 mm. the ribs are abruptly of a rounded type, while at an elevation of 25 mm. the ribs are obsolete. Specimens, probably of this same horizon, have been collected by J. E. Mills from the left bank of Merced River near Merced Falls, Cal., from the upper Tejon. Comparing these with eastern species it will be seen that V. planicosta hornii corresponds very well with V. planicosta regia Conrad, of the Aquia and Lower Chickasawan. V. planicosta ionensis and the Venericardia from Merced Falls correspond to a horizon similar to V. planicosta Lam.” and V. planicosta var. 6 from Wood’s Bluff,°® Alabama, of the Nanjemoy, Upper Chickasawan and Lower Claibornian; also to V. marylandica and V. potapacoensis of Harris’; also V. planicosta lati- cardo” of England. Since this manuscript was prepared, this subspecies has been described by the writer.°* The figured specimen with the ribs showing on the umbone is characteristic of the Ione formation. The form described by Mr. Dickerson from the Roseburg Quadrangle, Oregon” as V. planicosta merriann has not been found in the Ione of California. It is possible that the beds at the Oregon locality range a little higher than the Ione of Cali- fornia, which accounts for the presence of specimens with totally obsolete ribs. When V’. planicosta reaches this extreme stage in its evolution, it may be well to consider it a new species. _ These specimens were collected by Mr. Harold Hannibal in the Eocene of Wash- nee Harris, Bull. 9, Am.

Jury 30, 1917 V THE FAUNA OF A MEDIAL TERTIARY FORMATION AND THE ASSOCIATED HORIZONS OF NORTHEASTERN MEXICO* BY Roy E. DICKERSON AND WILLIAM S. W. KEw INTRODUCTION Professor E. T. Dumble has submitted to the California Academy of Sciences for identification and study some Ter- tiary fossils from the gulf coast of Mexico in the vicinity of Tampico and Tuxpan, the greater part of which were collected by Professor E. T. Dumble himself, Professor W. F. Cummins, Mr. Sands, and Mr. Muir. In all cases the fossils were care- fully marked and the localities well described. The collection localities are scattered along the coast both north and south of Tampico for a distance of 500 miles. The echinoids are particularly abundant and will doubtless prove to be excellent horizon determiners, because at several localities, they are associated with mollusks whose ranges are * The name “San Fernando,” originally applied by Prof. E. T. Dumble to these beds, has been found to be preoccupied. Professor Dumble now proposes that they be called the San Rafael beds. Printed from the John W. Hendrie Publication Endowment. July 30, 1917 126 CALIFORNIA ACADEMY OF SCIENCES (Proc. 4TH Ser. known. Some of the echinoids found here were described by Cotteau from the West Indies. The most widespread beds recognized in the medial are correlated with the Bowden and Gatun horizons and their fauna is an inshore facies of the Bowden. Some of the echinoderms described by Cotteau from the beds of supposed Eocene age are associated with character- istic mollusks of the Bowden stage, thus showing that the age of certain Antillean horizons are an inshore facies of the Bow- den, upper Oligocene or lower Miocene. The senior writer is responsible for the identification of the Pelecypoda, Gastropoda and some of the Echinoidea. The junior writer determined most of the echinoids and the de- scriptions of new species are written by him. STRATIGRAPHY The geology of this region has recently been discussed by Professor Dumble.t The accompanying map illustrates the general relations of the Tertiary beds north of Tampico. See Plate 16, which was kindly supplied by Prof. Dumble. Professor Dumble has described this region as follows: Overlying the beds we have here referred to the Eocene, we find a series of yellow sands, clays and calcareous beds which carry an Oligocene fauna. We have called these the San Fernando from the fine exposures of the beds in the vicinity of the town of that name on the Conchos River. (Locality x4.) As will appear, these beds all belong to the Upper Oligo- cene and up to this time no beds of the Lower Oligocene, like those of the Buenavista River region with Orbitoides papyracea, etc., have been rec- ognized in the area north of the Tamaulipas Range. From our present knowledge it would seem that while the Lower Eocene deposits show a gradual overlapping southward until the Conchos is reached, the Oligocene, on the contrary, shows an overlapping northward to the same region, so that along the Conchos the uppermost beds of the Oligocene are in con- tact with the members of the Eocene there exposed. In the region of San Jose de las Rusias, which occupies the extreme southern portion of this area, we have numerous exposures of the Upper Oligocene. (Localities x3, x5, x21, x22, and x23 are representative of this region. R. E. D.) It apparently immediately overlies the Cretaceous and is penetrated by eruptive rocks which are connected with or extend eastward from the Tamaulipas Range. The lower beds of the Oligocene in this region are yellow clays, which are altered in places and appear as hardened shales, and clayey limestones carrying Cristellaria, Nummulites, corals and molluscan forms followed by yellow sands and clays with an extensive fauna.

Lying four to six miles east of San Rafael there is a range of hills 300 to 400 feet in height, composed of alternating beds of yellow clays and clayey limestones carrying poorly preserved molluscan forms together with great numbers of Cristellaria, corals and some Nummulites. Among the corals collected here, Dr. T. W. Vaughan determined Favosites (3) polygonalis Duncan, Goniastrea antiguensis Duncan, Acropora (?), Sp., Orbicella, n. sp., and Goniopora, sp., very similar to or identical with an Antiguan species. These, he says, indicate an Upper Oligocene horizon about equivalent to the Chattahoochee of Georgia. Around the San Jose de las Rusias Ranch the beds which are exposed show considerable disturbance. Immediately at the ranch the beds, which are fossiliferous sandstones, dip northwest at a high angle. Northeast of the ranch a hill 60 feet high shows beds of yellow clay overlain by hard calcareous sandstone which weathers into rounded masses. A great number of corals occur within the clays and in the sandstone. Dr. Vaughan re- ports Orbicella cellulosa Duncan, and Meandrina, n. sp., from this locality. A short distance north of this hill is another in which the basalt has come up through the Oligocene beds which are here impregnated with asphalt. To the east of the ranch, some few miles, there is a range of hills 400 feet high capped with the Coquina, and lying to the east of the range another vol- canic hill. North of the Soto la Marina the same clays and limestones occur and east of the Salitre Ranch the same Orbicella was found as that occurring southeast of San Rafael, together with specimens of a new genus of the fungid corals. At and around Salitre were found three species of echinoderms (Agassizia clevei Cotteau, Clypeaster cubensis Cotteau, Clypeaster, sp. b occur at Localities x24 and x25. R. E. D.), the only ones so far found in beds we have recognized as Oligocene. A range of hills known as the Martines which are similar to those seen east of San Jose de las Rusias and of about equal height is found here extending from Salitre southward nearly to the Soto la Marina River. Along the Conchos River the exposures of the Oligocene are of beds higher in the series than the bulk of those of San Jose de las Rusias, being represented in that region by the Pecten beds which lie along its extreme eastern border. In the valley of the Conchos the greenish clays and soft sands with their beds of gypsum, which are part of the Frio, are found as far east as Tepetate and forming the body of the hills lying directly north. Beds of the Oligocene are found not only overlying these beds at this point, but stretching several miles westward, showing a clear overlap to lower beds of the Eocene section. What seem to be the lowest beds of the San Fernando section were found three miles west of that town, and consist of cross-bedded gray sandstones with a thickness of 60 feet. Half a mile east the beds form a series of falls in the river and we have the following section: Feet Conglomerates mean pcthe a ci ducchs Sace «Sor ee kil a Gat os ee de + Cross-bedded sandstone indurated and with bands of fossils........... 70 Mellowish sandstones watia' fossils. io oes eas ees ees de cokbas 3 Gray sandstones weathering in holes, few fossils................0.000. 4 The cross-bedded sandstone carries a great number of a large Pecten, which are well preserved, and, as it appears to be a well-marked horizon, we have called it the Pecten bed.

FAUNA Most of the localities listed below appear to belong to the San Fernando formation of Dumble. A very meagre fauna was obtained from localities x37 and x38 but it appears to be of Pliocene or Pleistocene age. Orbitoides cf. papyracea was ob- tained from localities x59 and x64 and these localities probably represent a lower Oligocene phase corresponding to the Vicks- burg. Unfortunately no mollusca were found with these forms. This list indicates the faunal relations of certain forms satisfactorily. The faunas from localities x14 and x24 are the keys to the relationship of the echinoderms and mol- lusks of known range. Thus locality x14 yielded Cidaris cf. lovent, sp., Clypeaster cubensis Cotteau, Macropneustes antil- larum Cotteau, Astarte, sp., Cardium, sp., Cardium lingua- leonis Guppy, Glycimeris, sp., Meretrix, sp., Ostrea trigonalis Conrad, Panope, sp., Pecten gatunensis Toula, Tellina, sp., Petalochoncus, sp., Hemipristis serra Agassiz, Architectonica, sp., Conus imterstinctus Guppy, Cyprea, sp., Malea ringens Swainson, Sinum, sp., Turritella, sp., Urosalpinx (?) sp., Xeno- phora, sp. Conus imterstinctus and Cardium lingua-leonis are forms characteristic of the Bowden beds; Pecten gatunensis and Pecten levicostatus are found in the Gatun horizons and Pec- ten condylomatus 1s a species previously reported from the Chattahoochee and Chipola horizons of Florida. The faunas from the Chattahoochee, Chipola, Bowden, and Gatun hori- zons represent somewhat different stages—or possibly facies, in part—of a great faunal assemblage which lived during a great period of submergence following the epi-Vicksburg in- terval. The occurrence of Clypeaster cubensis and Macrop- neustes antillarum with these mollusks of known range dem- onstrates that they are members of the Bowden fauna. Hemi- pristis serra, a shark’s tooth which occurs typically in the Miocene of Maryland and the Miocene of California is also reported at this locality.

VII] GESTER—GEOLOGY McKITTRICK DISTRICT 221 The Etchegoin age of these sands in the various fields is now determinable with considerable certainty. In the first part of the paper a typical example of the stratigraphic rela- tionships as determined by surface outcrops was given. The data obtainable from well records and surface exposures of the West Side fields show these conditions to be similar over a wide area. The only exception lies in the fact that there are apparent gradations between fresh water and marine forms in one or two localities, principally in the Kettleman hills. Mr. Cunningham” states, however, that in general even here there are evidences of a break between the marine and the fresh water formations. A few specimens of Cryptomya californica, which may be a brackish water type, were also obtained from a well in the Midway field just above the pro- ductive oil sands. The balance of evidence, however, is in- dicative of an unconformity at the base of the Tulare, particu- larly from the Lost Hills southward. Lost Hares The Lost Hills are a group of low hills, midway between Coalinga and Sunset, which rise but slightly above the valley floor. They are the results of a low anticlinal folding, a fold- ing which plunges and flattens to the southeastward. All sur- face indications in the Lost Hills pointed to their being a broad, flat fold. However, as drilling progressed, the pro- ductive sands were found to dip off at angles greater than the surface exposures seemed to indicate. Fossils from near the surface showed the upper strata to be of fresh water origin and of Tulare age. Fossils bailed from the Prestage well, Sec. 32, T. 26-21, at a depth of 380’ were determined as follows: Amnicola turbiniformis (Arnold). Carinifex marshalli (Arnold). Flumincola, species. Spherium cooperi (Arnold). Viviparus, species. Also from a well in Sec. 18, T. 26-21 at a depth of 600’ were found Amnicola turbiniformis (Arnold). Spherium cooperi (Arnold). *B.

Similar forms and fragments of Anodonta were noted by Mr. F. M. Anderson in a number of the Universal Oil Co.’s wells and by Dr. E. A. Starke in the wells of the Standard Oil Co. Invariably they come from fine sand or sandy shale a comparatively short distance above the oil sands. In the southern and eastern portions of the field the Tulare beds are much thicker than at the north. In and just above the oil and gas sands in many wells, in the Lost Hills, various species of marine Lower Etchegoin (Lower Pliocene) fossils have been found. Fragments of marine shells are reported in nearly all of the drilling records and some nearly perfect specimens have been either blown out by gas or bailed out of the wells. From one of the Universal Oil Co. wells, Sec. 32, the fol- lowing forms were noted at a depth of about 790 feet. Pecten crassicardo. Nassa californica. Echinarachnius gibbsi. Trophon ponderosum (?). Mulinia densata (Pseudocardium Macoma vanvlecki. gabbi). Cardium, species. Macoma inquinata. Chione, species. Pecten oweni. Similar forms including fragments of either Pecten estrell- anus, or Pecten eldridget, and Nassa californica were reported as coming from the oil horizon of the Standard Oil Co.'s wells, Sec. 4. No specimens from, or records of, determinable species from the lower oil sands in the Lost Hills are at hand, but this light gravity oil comes from sands in the lower part of the Etchegoin and from a sandy shale in the upper part of the Santa Margarita. There are two, and possibly three, oil sands recognized in the records of the Lost Hills wells, all within the limits of the Lower Etchegoin and other sands as shown in the accompanying diagram, which is typical of the general conditions that obtain in the Lost Hills. BELRIDGE Similar conditions obtain at Belridge as at Lost Hills, but incomplete records, due to a seemingly unnecessary caution on the part of some of the operators in not giving out records, have rendered a study of this field less complete. 224 CALIFORNIA ACADEMY OF SCIENCES (Proc. 4TH Srp. From the hills to the west and north of Belridge the out- crops show the same sequence as in Lost Hills, i. e., Tulare rests unconformably upon marine sandstones, shales, clays and oil sands which contain Etchegoin fossils. From the center of Sec. 21 and Sec. 27, T. 28 S., R. 20 E., in a sandy clay were found Pecten wattsi. Glycimeris septentrionalis. Cardium blandum. Zirphza, species. Nassa californica. Panope generosa. Solen, species. Solen sicarius. Mactra, species. Lunatia lewisii. Modiolus rectus. Crepidula grandis (casts). Pseudocardium gabbi (Mulinia Trophon near coalingensis. densata). McKITTRICK The McKittrick section has been pretty thoroughly repre- sented in the first part of this paper. The formations north and west of the ‘““South-End Area” are badly broken up by an overthrust faulting, but the presence of rather character- istic fossils from the oil horizon, as well as the general charac- ter of the materials in which the oil occurs has led the writer to believe that at least the greater part of the oil sands belong to the Etchegoin formation. From the San Souci well, Sec. 18, T. 30S.) R: 22 E.; at’a depth of about 1400 feet, large fragments of Pecten crassi- cardo and Ostrea vespertina were blown out by a gas ex- plosion. Pecten eldridgei and Cryptomya ovalis were obtained from a, Similar horizon. trom a, well in. Sec: 12, T. 30,S., R. 2178: The logs of numerous other wells record “Sea shells” but it is only occasionally that these can be specifically determined. In the Midway-Sunset field the Etchegoin age and some of the stratigraphic relationship of the oil bearing series is de- terminable from well records, with considerable accuracy. However, on account of the overlapping of the Tulare upon the older formations, it is only occasionally, and in restricted areas, that the Etchegoin is exposed on the surface. At two localities Etchegoin fossils were found and the stratigraphic sequence determined. Vor. VIT] GESTER—GEOLOGY McKITTRICK DISTRICT 225 Southeast of old Sunset, poorly preserved fossils are found associated with outcrops of brea from which the following species could be determined : Mulinia densata. Nassa, species. Mya japonica. Solen, species. Pecten, species. These fossil beds are overlain unconformably by the fresh water Tulare and, while the lower contacts are not clearly de- fined, yet there is a suggestion of an unconformity at the base of the oil bearing Etchegoin formation. West of Fellows these conditions are duplicated. Similar poorly preserved fossils are to be found in a small belt of Etchegoin conglomerates, sands, sandy shales and marls, that overlies the Santa Margarita. The latter at this locality is composed of organic shales with fossiliferous sandstone and boulder lenses. At this locality an interesting and satisfactory correlation between surface exposures and well record was obtained. The top of the Etchegoin, containing oil sands and fossils, dips at 25° to 27° N. 25° E. Down the dip at a distance of 1950 feet is well No. 9 of the United Oil Co. At a depth of 928 feet a gas and oil sand was struck in this well, and the gas pressure threw out large fragments of fossiliferous oil sand and shells. The determinable fossils collected from these fragments were: Cardium blandum. Metis alta. Mya japonica. Mulinia densata. Arca trilineata. Pecten, species (P. estrellanus?). Macoma nasuta. Nassa, species. Macoma secta (?). Ostrea, species. Neverita reclusiana. Fragments, with Pholas borings. This association of forms is quite characteristic of the Lower Etchegoin formation. Also a simple calculation shows that the fossil bearing oil sand on the surface is very probably the same as that found at 928 feet in the well. In many of the wells, around Fellows and to the northward, fragments of marine shells are reported with, or just above, the oil sands. Numerous occurrences of fossils are reported from the oil horizon in the Midway flats and, while many fragments were obtained and examined, it is only occasionally that con- 226 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. clusive inferences can be drawn. In well No. 4 of the Midway Consolidated) Oil Co, ‘See.'42 1 32S) Rey Z3) Ee Me ah from the lower oil sand at a depth of 3437 feet, a number of good specimens of Echinarachnius gibbsi were obtained. On the Buena Vista Hills the surface structure is self-evident and Tulare fossils are to be found in the surface exposures. The underground sections, however, show that the oil sands as a rule exhibit variations and show greater dips, not found on the surface exposures. Also numerous fragments of marine shells are associated with the oil horizon. The fragments seem to be mostly of such forms as Mya japonica, Macoma inquinata and Mulinia densata, though these determinations are perhaps questionable. To the south on the Sunset flats in Sections 25 and 36 of T. 12 N., R. 24 W., and on sections 31 and 32 of T. 12 N., R. 23 W, and Section 5 of T. 11 N., R. 23 W., S. B. M., character- istic Etchegoin fossils have been obtained from the oil horizon. EniwelluNios Mi Kei \t.& O. Go, Section: 25, IF, 31-22, very characteristic fossils were obtained, including : Echinarachnius gibbsi. Solen, species. Pecten, species. Ostrea, species. Arca trilineata. Nassa californica. Macoma inquinata. Mulinia densata. As in the Buena Vista Hills, so also on and near the surface in the Sunset flats, are found fresh water Tulare fossils. Both forms of Anodonta and some small gastropods were obtained from a small open cut in Section 32, T. 12 N., R. 23 W., S. B. M. The data at the present time are not sufficient to say that all the productive zones of the Midway-Sunset field are entirely confined to the Etchegoin. The data are sufficient, however, to place most, if not all, the oil sands below the Tulare and in a marine formation. The fossils found directly above the oil zones and in the oil sands, as obtained from productive wells, are most characteristic of a Lower Etchegoin age. On the surface, however, there are sandstones in the form of lenses found in the Santa Margarita. Traces of oil are found in some of the surface exposures of these lenses and it is possible that wells penetrating similar buried lenses may obtain productive quantities of oil. Vor. VIT] GESTER—GEOLOGY McKITTRICK DISTRICT 227 In the Belridge, and possibly in the Lost Hills, some oil comes from the Tulare, but the Etchegoin is here, also, the principal oil producing formation. The Santa Margarita of these fields is productive of some light oil from its more sandy members. In all of these West Side fields both surface exposures and well records indicate distinct unconformities between the Santa Margarita and Etchegoin and between the latter and the Tulare, and place by far the greater part of the present oil pro- duction from oil sands in the Etchegoin formation.

SEPTEMBER I, 1917 Xx NOTES ON WEST AMERICAN CHITONS —I* BY S. STILLMAN BERRY, REDLANDS, CALIFORNIA 1. Notes on CHITONS COLLECTED BY Mr. GEORGE WILLETT IN SOUTHEASTERN ALASKA In the present paper are given the preliminary results of the examination of a considerable series of chitons collected by Mr. George Willett in southeastern Alaska during the summers of 1913 to 1916, inclusive. Although chiefly occu- pied with other business, his personal interest in the group caused Mr. Willett to devote odd moments to the collection of mollusks, both on shore and, by means of a small dredging outfit, in depths down to 50 or more fathoms. The Polypla- cophora comprise an important part of the spoils obtained, both individuals and species being extensively represented. Mr. Willett has generously placed at my disposal for investi- gation the entire series of over 600 specimens, along with certain verbal field observations of sufficient ecological inter- est that I have quoted from them freely. A small portion of the material was fortunately preserved in alcohol and has proved invaluable, though not all the species taken are repre- sented in this way and several interesting problems must therefore go over until further material can be obtained. * Printed from the John W. Hendrie Publication Endowment, September 1, 1917 230 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. As indicative of what careful and exhaustive collecting will accomplish for such a group as the chitons, even in a re- stricted locality, | may mention that Mr. Willett’s first invoice of specimens sent me from his 1914 collection included thir- teen species. The number has since been increased to the present total of twenty-four species and one subspecies, yet I am certain that this figure is by no means complete for the region involved, and perhaps not even exhaustive for the collections as they stand. While the bulk of Mr. Willett’s collecting was done at For- rester Island, a small oceanic island at the extreme southern end of the territorial jurisdiction, he also did some work at the Waterfall Cannery on Prince of Wales Island, just inside Cape Lookout on Dall Island, and at Sitka, all these last local- ities being on the western or oceanic coasts of the island chain, though protected from the open ocean itself, so that the water is relatively calm. He reports that Tonicella lineata is everywhere by far the most abundant shore chiton. This and Katharina (also abun- dant) occur on rocks between tides, whereas Ischnochiton mertensi (common), J. trifidus (rare), Schizoplax, and Lep- tochiton, characteristically occur on the under sides of rocks “at pretty low tides (—1.0 foot). Cyanoplax is another characteristic shore form, being fond of crevices. In shallow depths (15 to 25 fathoms), just beyond the kelp line, and found mostly adhering to the inside of old mussel shells, oc- curs an interesting association: Leptochiton cancellatus, Ton- icella limeata, juv. (common), 7. ruber, T. submarmorea (rather rare), [schnochiton interstinctus (abundant), I. reti- porosus, I. trifidus (rare), I. mertensii (abundant), I. willetti (common), Trachydermon flectens (rather rare), Mopalia ciliata, M. imporcata, and M. sinuata. These occasionally occur also on rocks hauled up in the dredge, but Mr. Willett states that the shells are a favorite situs. Placiphorella rufa, on the other hand, is found occasionally on shells, but gen- erally on rocks. In deeper water (40 to 50 fathoms) Ischno- chiton retiporosus was the only form commonly obtained. In the present paper two species, /schnochiton (Lepido- zona) willetti and Placiphorella rufa, are described as new. Vor. VIT] BERRY—WEST AMERICAN CHITONS 231 Where possible a series of duplicates, including paratypes of the new species, has been deposited in the collection of the California Academy of Sciences. Mr. Willett has also generously permitted my personal retention of a considerable series of specimens, further data from which are accumulating and will be offered on a subse- quent occasion. Below is given a systematic list of all the species so far identified. Following the list are given notes on the various forms with a memorandum of the localities at which they were obtained, and such ecologic data as are now possible. SYSTEMATIC List oF SPECIES.

Leptochiton cancellatus (Sowerby) Taken in 20 fathoms at Forrester Island in 1915. This is the smallest chiton in the collection and one of the smallest species we know. The rehabilitation of Gray’s old genus Leptochiton may occasion some surprise, but perhaps not to those who have felt with the writer that Lepidopleurus Risso, in the sense in which it has been commonly used, is little but an amorphous Vor. VII] BERRY—WEST AMERICAN CHITONS 233 mixture. The relatively delicate and smooth-shelled Lepido- pleuride of the west American coast seem only diffidently congeneric with L. cajetanus Poli, the thick rugose shell se- lected by Pilsbry as Risso’s type. It may be that further anatomical work will require the dismemberment even of Leptochiton, but in the meanwhile it does not seem to strain the relationships seriously to make this genus do duty again. 2. Leptochiton, species Numerous specimens of a worn Leptochiton, recalling the southern L. rugatus, were taken “at pretty low tides” at the Waterfall Cannery, Prince of Wales Island. One specimen of the same was also taken at Cape Lookout, Dall Island. It occurs under rocks. Whether the specimens are really ruga- tus or some undescribed form must be determined by fur- ther study. They differ from southern California (La Jolla) specimens of rugatus in their much smaller size, whiter color- ation, more. pilose girdle and flatter posterior valve, only slightly if at all concave behind the mucro. 3. Tonicella ruber (Linnzus) Taken at Forrester Island in 15-30 fathoms, occurring in association with the small Tonicella I have here taken to be young lineata (Wood). Balch (:06, p. 62) has remarked at length upon the ap- parent close relationship of this species and Tonicella mar- morea. Ruber had for years been placed by nearly all writers in Trachydermon, and to avoid separating the two generic- ally, Balch thereupon removed marmorea to Trachydermon, leaving the genus Tonicella to whatever might be its fate after the loss of its type species. For reasons which will presently be given in another connection, I have come to the conclusion that Trachydermon is quite a different group from what has generally been understood, but since both Sykes (°94, p. 36) and Thiele (:10, p. 107) have shown cause for referring ruber itself to Tonicella, there is a convenient way out of the difficulty. 234 CALIFORNIA ACADEMY OF SCIENCES [Proc. 47H Ser. 4. Tonicella lineata (Wood) This species is reported by Willett as by far the most abundant of the shore chitons in all the localities he visited, though all the specimens seen by me were taken at Forrester Island, some on shore, the remainder dredged in from 10 to 30 fathoms. The shore specimens are stated to be usually found on top of the rocks in association with the very dissimilar Katharina, and their beautiful coloring is almost always obscured by a green deposit very difficult to remove. It is interesting to note that all the dredged specimens I have included here run very much smaller than those taken between tides, including not a single specimen larger than 21x12 mm. (gross measure- ments "of ay specunen in, alcohol; (SiiS. Bi 2914) ey Willett even writes on one of his labels: “I consider this entirely distinct from the true lineata. It is confined to deep water, not occurring in shallow water with latter.” However, ex- cept for a certain curious uniformity in general facies, I have been unable to find any dependable evidence (among eternal characters alone) confirming this opinion. It may be men- tioned also that whereas there are no large specimens among the dredged material, I have on the other hand seen no small ones from the shore. 5. Tonicella submarmorea (Middendorff ) Taken in 15 to 25 fathoms at Forrester Island. Willett reports this species as “not common and always dredged.” All the specimens are rather small. The prevailing color is usually a beautiful rose red. 6. Cyanoplax raymondi (Pilsbry) Taken at Forrester Island, and at the Waterfall Cannery, Prince of Wales Island, “invariably between tides.” This species “likes to get in a crack in the rocks,’ though it is sometimes found on top. Vor. VII] BERRY—WEST AMERICAN CHITONS 235 7. Schizoplax brandtii (Middendorff ) Taken at Forrester Island, and at the Waterfall Cannery, Prince of Wales Island.

Ischnochiton interstinctus (Gould) Dredged in 10 fathoms in Sitka Harbor in 1913, and in 10 to 20 fathoms at Forrester Island in the three subsequent years. This and J. mertensii are by far the most abundant of the dredged species. It was not taken between tides. 9. Ischnochiton radians Carpenter Specimens which seem unmistakably to belong to this species were taken on shore at the Waterfall Cannery, Prince of Wales Island, and near Cape Lookout, Dall Island. So far as I have been able to ascertain, they constitute the first Alaskan record for the species. Barkley Sound, B. C., was previously the most northern station recorded. I. radians and I. interstinctus are very closely related and though most lots may be readily separated by their relative size and color, some of the specimens are sufficiently inter- mediate so that with occasional undissected shells I have had to fall back upon the blue-green interior usually pos- sessed by radians and similar trifling features to separate them. Three of the four specimens taken at Dall Island [S. S. B. 258] are of a peculiar dark color variant which is also found occasionally in the vicinity of Monterey. 10. Ischnochiton (Lepidozona) retiporosus Carpenter Taken at Forrester Island in 15 to 50 fathoms. While dredged occasionally in 15-20 fathoms in association with 236 CALIFORNIA ACADEMY OF SCIENCES [Proc. 47H Ser. 1. wnterstinctus, it is more abundant in the deeper water. One specimen in alcohol [S. S. B. 236] is close to if not identical with the var. punctatus Whiteaves. Thiele (:10, p. 87, 107) transfers this species to Callisto- chiton, but this step I do not yet feel ready to follow. 11. Ischnochiton (Lepidozona) mertensii (Middendorff) Numerous specimens of this species are in the collection taken between tides and dredged (15-20 fathoms) at Forres- ter Island, and between tides at the Waterfall Cannery, Prince of Wales Island. At Forrester Island Mr. Willett found it one of the two most abundant chitons in his dredge. The specimens are almost all of the plain red-brown variety, the girdle obscurely maculated in two shades of brown. Less common, but equally constant in their peculiarities, are two other color forms, analogous variations of which are also commonly seen in California suites of this species: 1) a form in which the valves are irregularly maculated with various shades of brown, the alternate bands of color on the girdle being usually quite regular and prominent; 2) a form in which the jugal areas of the second and seventh valves are usually darker than the general red-brown ground color, and help to set off a cream-colored band nearly as wide as the valves, which extends down the side slopes and across the girdle, the latter being otherwise nearly unicolored. 12. Ischnochiton (Lepidozona) willetti, new species Numerous specimens occurring at Forrester Island in 15 to 20 fathoms in company with /. mertensii, might easily be over- looked as another color variety of the latter, but appear upon careful examination to represent an undescribed species, which may be briefly treated as follows: Diagnosis: Shell rather large, regularly elliptical (fig. 1) ; elevated, with an angular dorsal ridge and arcuate side slopes. General surface indistinctly granulose. Anterior valve with 35-45 low, occasionally bifurcating, radiating ribs, separated by shallow distinct grooves and bear- ing a variable number (normally 8 to 10) of small, well sep- Vor. VIT] BERRY—WEST AMERICAN CHITONS 237 arated, distinct, rounded pustules. Median valves: lateral areas distinctly raised, sculptured like the anterior valve, but the 5 to 7 ribs relatively wider and more flattened, the defining Fig. 1. Ischnochiton (Lepidozona) willettti Berry, camera outline of dorsal aspect of type specimen, x1. grooves sometimes, but not always, sharply chiseled (fig. 2) central areas on each side sharply sculptured with 20-25 nar- row, faintly beaded, longitudinal ridges, their interstices trav- ersed by low, rather irregular cross-ridges, becoming nearly or quite obsolete at the jugum. Posterior valve with mucro well in front of center; region behind mucro sculptured like the an- terior valve, but the 28-30 ribs rather less distinct and the 2 2 Cin. = Fig. 2.

Interior of central valves thickened across the middle. Teeth with a distinct fossa separating them at base from body of 238 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. shell, their edges roughened, those of the posterior valve almost crenate. Anterior valve with 11, second valve with 2-1, third to seventh valves with 1-1, posterior valve with 12, slits. Girdle wide, regular; covered dorsally with a closely imbri- cating armature of large, smooth or barely striated, convex scales, each normally bearing a short, striated, nipple-shaped process projecting upward from the dorsal end. Color of outer surface of shell a reddish brown of varying intensity in different specimens, sometimes nearly black; girdle lighter. Interior of shell light salmon. Maximum length of the type and largest specimen 29.5 mm. ; width 16 mm. Type: A shell preserved dry [S. S. B. 159] as Cat. No. 3700 of the author’s collection. Paratypes have been deposited in the collections of the California Academy of Sciences, the Academy of Natural Sciences of Philadelphia, the United States National Museum, and the private collection of Mr. George Willett. Type Locality: 15-20 fathoms, Forrester Island, Alaska; George Willett, May-July-August, 1914-1916; 36 specimens. Remarks: As above noted, this species has a close superficial resemblance to its associate and congener, J. mertensu. It is easily recognized, however, by its narrower outline when viewed vertically, the grooves chiseled between the ribs of the terminal and lateral areas, its finer sculpture, and generally characteristic darker red-brown coloration. A nearer relative is possibly a species now being described as J. interfossa Berry, from northern Japan, but the more arcuate side slopes, the less pitted sculpturing of the central areas, and again the color, fur- nish easy distinguishing marks. 13. Ischnochiton (Ischnoradsia) trifidus (Carpenter ) One specimen of this interesting species was taken at a very low tide near the Waterfall Cannery, Prince of Wales Island. Five others were dredged in 15-20 fathoms at Forrester Island in company with J. mertensu. Mr. Willett believes it to be a rather rare species. Vou. VITJ BERRY—WEST AMERICAN CHITONS 239 14. Trachydermon flectens (Carpenter ) One specimen of this species was taken at low tide inside Cape Lookout, Dall Island. Others were dredged at Forrester Island in 15-30 fathoms. My reasons for the unusual position in which I have placed Trachydermon in the list will be given in the next note of this series. 15. Mopalia ciliata (Sowerby) Four specimens more or less referable to typical ciliata as redefined by Pilsbry were taken in 15 fathoms at Forrester Island) ['S;.5)8, 278k The last word has not been said on the West American Mopalize, and I have no hope that my treatment of them here, merely adapted as it is from work done a considerable period ago, can be more than provisional. This remark is not to be construed as an attempt to carp at the older work. That of Pilsbry in particular constituted a tremendous advance in our understanding of the entire group and stands alone not only as a reference work, but as a priceless text and source of inspira- tion to every subsequent student of Polyplacophora. But dried specimens, upon which most taxonomic work in this group has perforce been done, are often extremely deceptive, and this is notoriously the case with the Mopalias. In this instance it is going to require a far more extensive array of well-preserved alcoholic material than exists at present, I fear, in all our col- lections, to definitely settle the status of the numerous named forms, let alone the many others which still remain to be de- scribed. No doubt Dall and Pilsbry have generally been quite correct in reducing many of the earlier species to synonymy, but I feel certain that in some cases the process has been carried too far. Some of Mr. Willett’s small Mopalias form a curious as- semblage, but the series is not sufficiently complete and the proportion of specimens preserved in alcohol too scanty to permit the drawing of satisfactory conclusions from them at the present time, though I think it apparent that not all are to be regarded as young stages of the older species. The Mopaliidz are never an easy group, but the difficulty of dealing with them 240 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4rH Ser. is increased by the fact that the young do not always closely resemble the adults, and the girdle characters, which seem to be of the highest importance in separating the species, are usually almost impossible to make out correctly in dried ma- terial. The members of the sinuata-imporcata group are at times particularly puzzling. Those having opportunities to collect them should not fail to see that any bearded chitons they may chance to find, however minute, are carefully fixed in the expanded state and preserved in alcohol. No attempt should be made to clean or dry them, lest valuable material lose much of its significance. 16. Mopalia ciliata wosnessenskii (Middendorff) Taken on shore at Forrester Island, at the Waterfall Can- nery, Prince of Wales Island, and inside Cape Lookout, Dall Island. The specimens are quite variable, some very elevated for this subspecies, some depressed, and running through a whole gamut of color forms. A few of the dried specimens from Forrester Island are unusually long and narrow. 17. Mopalia hindsii (Reeve) Seven specimens were taken at low tide on Forrester Island. All are of exceptional size, one in Mr. Willett’s collection [S. S. B. 308] measuring in the dry condition as follows: Maxim lensthvor animal s.0) 2G. eee bine cease «3 90))) mm: Miasimunn widthnat animal’ 2), -)s.c. see eel 45.5 mm.

Mopalia lignosa (Gould) This is apparently a rare species in this region, as Mr. Wil- lett took but one specimen at Forrester Island in 1914, none in 1915, and again one in 1916. Two were found near Cape Lookout, Dall Island in 1915. All the specimens were taken on shore. Vot. VII] BERRY—WEST AMERICAN CHITONS 241 19. Mopalia muscosa (Gould) This species would appear to be excessively rare, only a single specimen having been taken inside Cape Lookout, Dall Island, and none at all at the other localities. The specimen is not a very large one, but seems typical. 20. Mopalia imporcata Carpenter Dredged in 15-25 fathoms at Forrester Island, and appar- ently the common Mopalia in all the shallower depths. The specimens are very uniform in size and general appearance, but exhibit some variation in the minor details of sculpture. 21. Mopalia sinuata Carpenter A few specimens were taken with the last species in 15-20 fathoms at Forrester Island, but not very frequently. 22. Placiphorella velata Carpenter In Mr. Willett’s experience this is another of the notably rare chitons. Only two specimens were taken, both at low tide on Forrester Island in 1915. 23. Placiphorella rufa, new species More common than P. velata at Forrester Island, though always dredged, is the very interesting Placiphorella now to be described. Diagnosis: Shell of moderate size, broadly oval in outline, depressed. Dorsal ridge only moderately elevated, the side slopes little convex. Anterior valve crescentic, showing strong, irregular lines of growth and occasional weak traces of radial grooves. Median valves with the lateral areas raised into diagonal and sutural ribs having a groove-like depression between; otherwise un- sculptured except for the strong, uneven lines of growth, especially prominent where they traverse the ribs; not beaked. Posterior valve small, only about half as wide as the anterior valve; sculptured by two strong, oblique ribs converging to the depressed, distinctly posterior, but not marginal, mucro. 242 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. Interior of valves calloused. Anterior valve with 9 strong, distinctly cut insertion teeth, the 3 anterior concave, and all coarsely grooved on their outer surfaces ; slits 8 in number, their porous apices connected with the apex of the valve by lines of minute pores. Central valves with wide, gently arcuate sutural lamin, scarcely if at all connected across the rather deep sinus ; slits 1-1. Posterior valve with a barely indented flattening in- stead of a posterior sinus; slits 1-1. Eaves distinctly spongy. Girdle of moderate width posteriorly, broadening in front to the wide lobe characteristic of the genus, so that the maximum diameter of the animal is in the region of the head (text figs. 3-4). To the naked eye or under lenses of moderate power the girdle appears smooth and nude over its entire area dorsally* save for a marginal palisade of minute hyaline spinelets, and three or four submarginal series of armored chetz, the mem- bers of the inner series of which are conspicuously the largest and extend clear around the girdle, about 12 chzetz in this series encircling the anterior lobe, the remainder placed 1 opposite each suture and 2 directly behind the tail valve. The ventral surface of the girdle is clothed with very minute scattered spinelets, visible only under quite a high power. In dried speci- mens the girdle becomes excessively thin and leathery.

From P. velata and its analogue P. stimpsoni, our form is readily distinguishable by its warm, ruddy external 244 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. coloration, warm flesh and salmon tinting of the interior of the shell, pale anterior lobe, nearly nude girdle, and the marginal position of the sete. Further characters to be noted only on dissection are the spongy eaves, curious rows of pores in the anterior valve, open sinuses, and sharply cut teeth. This com- bination of features should effectually prevent the confusion of P. rufa with any of the described forms. It is an important addition to our fauna. 24.

ON THE GENUS TRACHYDERMON In the preceding note I have briefly mentioned the species Trachydermon flectens Carpenter and indicated my belief that the genus should be interpreted in an altogether different way than has heretofore been recognized. This is entirely due to the fact, brought about quite incidentally by a strict adherence to the rules of the International Code of Zoological Nomen- clature, that because of its subsequent selection for that rank by Pilsbry, T. flectens must be recognized as the type of Carpen- ter’s genus. This exquisitely beautiful little chiton has been known for many years and is frequently met with in collections, yet, 1f I am correct in my identification of such specimens as I have seen with Carpenter’s type, it has been one of our most misunderstood species. While its reference to the Mopaliidz will no doubt occasion general surprise and will probably not be allowed to pass unquestioned, it seems to me clear that T. flec- tens has little in common with any of the numerous other species commonly ranked with it, and which latter I fear Car- penter himself really had most in mind at the time he founded his genus. It does not even belong in the subfamily to which in recent years it has given its name. Fortunately the recent rehabilitation of Gray’s Lepidochitona by Iredale ( :14, p. 127) has already precipitated the nomenclatorial changes which would otherwise have been the inevitable result of removing the type species of Trachydermon to another family. The accumulation of evidence which has finally led me to the adoption of the course outlined had its beginning in the almost absolute parallel which is to be found between Pilsbry’s de- scription and figures of 7. flectens in the concluding part of the “Manual” (793, p. 64, pl. 15, figs. 34-37), and his later description of Mopalia heathu (98, p. 288). By tabulating in parallel columns the essential items, not only of these two de- scriptions, but of Carpenter’s own brief diagnosis (Pilsbry, ’92, p. 75) and the present writer’s more recent redescription of heathu (Berry, :11, p. 490, text figs. 4-7, pl. 40, figs. 1-3, 7), the strength of the evidence can be more readily appreciated and the reader then left to draw his own conclusions. Such discrepancies as then appear are thus thrown into relief for consideration later. 246 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. if T. flectens Carpenter MS. Shell subelongate; jugum acute.

VIT] BERRY—WEST AMERICAN CHITONS 247 Considered in connection with the figures given by Pilsbry (93, pl. 15, figs. 34-37) and myself (:11, pl. 40, figs. 1-3, 7), the table appears to me conclusive that the specimens identified by me in 1911 as Mopalia heathii (column 4 above) are cer- tainly congeneric if not specifically identical with Trachyder- mon flectens Carpenter, as interpreted by Pilsbry (column 2). Down even to such details as size, color, and station the par- allel is an instructive and telling one. But in view of the ad- mitted source of possible error due to my having access to neither of the type specimens concerned, it would be folly to overlook the difficulties offered by the various discrepancies in columns 1 and 3. As to column 1, the only trouble lies in the large number of slits quoted for the head and tail valves and the description of the girdle. The former may or may not be an essential matter, depending on whether the number printed be a lapsus (which I do not believe), or may indicate an ab- normal specimen, or may (which appeals to me as the most probable) come within the limits of normal variation, already noted as considerable in the Monterey specimens described in column 4. The discrepancy in the description of the girdle in column 1 as compared with column 4 is also shared by column 2. This appears at first sight the most serious of all, but I think is very easily accounted for by the very delicate and brittle con- sistency of the bristles, which I find to be almost invariably broken off in dried specimens in such a way as frequently not to leave the slightest trace of their previous existence. This is brought out very clearly in the series of specimens taken at Forrester Island by Willett, all of which were preserved dry, but which reached me soon enough afterward so that I was able to make out the character of the bristles. In most of these the bristles, however, appear either as mere stubs or so nearly in- distinguishable that in the absence of some suspicion of their presence they might never be detected. It is only in living or alcoholic material that the full characters of this species are evident.” ?It is worth while noting that specimens from the original lot of “Trachydermon flectens montereyensis Bartsch”, a nomen nudum which has appeared several times in print, are in every respect completely identical with the specimens referred to by me as M. heathti in column 4 above. From similar evidence there is no doubt that “Cheto- pleura rosetta Bartsch’, another nomen nudum which has found its way into the literature, falls into the absolute synonymy of Dendrochiton thamnopora. I can as yet discover no evident connection of this species with the genus Chetopleura. j 248 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4rH Ser. Let us now pass to column 3. Pilsbry, who is a careful ob- server, states that beyond the bristles the girdle is nude. This statement and the unusual size of his type specimen do not fit in well with the remainder of the table, though the weight of all the rest of the evidence would indicate that Mopalia heathu Pilsbry must fall as a synonym of T. flectens. Can it be barely possible that there are two species involved in the original de- scription of M. heathu? This, with other correlative points, will receive attention in a later communication. From evidence before me, my present inclination is to give both Trachydermon Carpenter, as redefined (type: T. flectens Carpenter), and Dendrochiton Berry, 1911 (type: Mopala (D.) thamnopora Berry) full generic rank, referring both, though only tentatively, to the family Mopaltide.

DEcEMBER 31, 1917 XI REPORT UPON A COLLECTION OF HEMIPTERA MADE BY WALTER M. GIFFARD IN 1916 AND 1917, CHIEFLY IN CALIFORNIA BY EDWARD P. VAN DUZEE Curator, Department of Entomology Mr. Walter M. Giffard of Honolulu has very kindly turned over to me for study all the Hemiptera taken by him in Cali- fornia and adjacent states during the summers of 1916 and 1917. Most of his collecting was done in central California, largely about San Francisco Bay region, a district in which little systematic collecting of the Hemiptera has heretofore been attempted. Many general collectors have worked about this portion of the state and a considerable number of the Hemiptera taken have been described by the entomologists of Europe and the eastern United States. Among the principal papers including such material may be mentioned Stal’s Re- port on the Hemiptera of the Fregatten Eugenies expedition, Uhler’s Report on the Hemiptera from west of the Mississippi River and his Report on the Hemiptera of Lower California, Ball’s various papers on western Jassids and one by the writer ona few Hemiptera collected by Mr. D. W. Coquillette in Cali- fornia. But two general faunal papers on our California He- miptera have yet been published, both by the present writer, one in 1914 covering his work in San Diego Co. and includ- December 31, 1917 250 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. ing 392 species, the other enumerating 140 species taken by him during July, 1915, at Fallen Leaf Lake in the Tahoe region. The present paper enumerates 355 species and gives a somewhat similar survey of the Hemiptera of central west- ern California together with a few forms taken by Mr. Gif- fard in the Sierra and elsewhere. The material taken by Mr. Giffard was obtained during a few short collecting trips he was able to make to some of the more interesting and promising localities about the bay and elsewhere, and altogether represents but a comparatively few hours of actual work. That he was able to secure so many rare and interesting species is but another indication of the systematic methods of collecting which has characterized his work here and on the Hawaiian Islands. His notes on food- plants, habits, etc., have mostly been left for future elaboration and publication. Some of the more important localities he visited are listed below to save the repetition of details. San Francisco, collections made at Lands End, Presidio and Forest Hills on various dates.

Antenne rather slender, nearly as long as the head and pronotum united; first seg- ment a little longer than wide; second moderately narrowed to the base; third and fourth together scarcely longer than the second, becoming slightly thinner apically; fourth three-fourths the length of the third. Pronotum short, the expanded sides forming an angle at the humeri, the latero- anterior margins rectilinear, the latero-posterior nearly so, these margins with about five rather large teeth anterior to the humeri and some finer granulations posteriorly; posterior excavation shallow; the six dorsal carine prominent, the lateral abbreviated at the expanded margin; mar- ginal carina of the scutellum much elevated. Elytra about as wide as in duzei, attaining the apex of the ultimate tergal segment. Margin of the abdomen evenly rounded, with but a small notch at each incisure genital plate truncately rounded, unarmed. Color dark fuscous brown: basal segment of antennz touched with ferruginous; third segment pale yellowish, with its immediate base black; apex of the last segment clothed with pale hairs; hind edge of the pro- notum touched with ochraceous; expanded latero-anterior margins with an elongated white spot. Scutellum black at apex, the marginal carina with a median white mark. Elytra whitish, varied with black, especially toward the apex, the extreme tip black.

Length 3%, width 134 mm. Pronotal hood about as in spinosa Champ., but somewhat more produced and vertical before where it surpasses the apex of the first antennal joint; viewed from the side about one-half higher than the median carina and regularly arcuated above; viewed from above nearly globose behind, but not at all transverse; this portion not suddenly con- tracted before and with the areoles rather large and distinct, those of the anterior portion smaller; median carina more depressed anteriorly than in spinosa as figured by Champion, highest about the anterior one-third. Expanded sides of the pronotum elliptical before, almost suggesting an angle there, scarcely surpassing the first antennal joint: areoles small and regular, averaging about one-half the size of those on the posterior aspect of the hood, the marginal row scarcely larger than those of the disk; marginal spines short, but little more than half as long as the width of the marginal areoles. Scutellum shorter and broader than in spinosa, the elevated margins continued nearly across the pronotal disk. Closed elytra considerably narrowed posteriorly, each elytron widened nearly to its apex; areoles smaller at base with a few larger ones before the apical dark band; humeral angles well rounded; gibbosities rounded, scarcely higher than the median carina of the pronotum; marginal spines short like those of the pronotum. Body deep black; legs and antenne fulvo-testaceous, black at tip; membranous portion whitish-hyaline with white nervures; disk of the pronotum deep polished castaneous margined with black; nervures of the hood and expanded pronotal margins largely fuscous; scutellar carine white, the median with an oblique black vitta; pronotal margins with two fuscous spots, a smaller one before the middle and a larger one at the middle of the hind lobe; margin of the elytra with a similar spot placed about its own width behind the anterior edge, not attaining the humeri, and a transverse band of about the same width just beyond the tip of the abdomen; posterior aspect of the gibbosities fuscous, the discoidal region more obscure. Described from eight examples taken at San Diego, Calif., May 30, 1913. Mr. Fordyce Grinnell has sent me the same species from Pasadena, taken in June, and from Prof. H. F. Wickham I have received a long series, taken at Nephi, Utah, June 30. I also took it at Boulder, Colo., July 21, 1903, and at Manitou, Colo., a few days later, and more re- cently Mr. Giffard has taken the same species in the Yosemite Valley, June 16, 1916; in Placer Co., at about 5000 feet altitude, August 20, 1916; on the shores of Clear Lake in Lake Co., August 2, 1916; in Muir Woods, August 16, 1917, and in Redwood Canyon, August 6, 1916. This is the form I have listed as fuscigera from San Diego, but Champion’s figure of that species shows it to be a larger insect, in which the pronotal hood is broader posteriorly and suddenly contracted near the middle; the anterior fuscous 258 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. spot of the elytra is extended to the humeral angle and the posterior spot is larger and reaches nearly to the apex and encloses about three large clear areoles.

Lake Co., along the road between Hoberg’s Resort and Lakeport on Hoosackia crassifolia, where it was abundant with its young, August 2, 1916. This may be distinct from Stal’s species, but it agrees much better with Champion’s figure than does the preceding. This species and its allies have probably formed the basis for the records of fuscigera in this country. 63. Corythucha eriodictyonae O. & D. Mt. Tamalpais, August 16, 1916; abundant at West Point. Very near setosa Champ., but perhaps distinct. 64. Corythucha bullata, new species Closely allied to juglandis Fh., a little smaller than the average in that species, with the pronotal hood more spherical posteriorly and the elytral cyst larger and more prominent. Length 34% mm.; humeral width 2 mm. Pronotal hood viewed from above globular behind, broader than in juglandis, more produced before, its apex considerably surpassing the second antennal segment, the areoles a little smaller and more numerous posteriorly; viewed from the side regularly rounded above, not at all subangulate as in that species. Expanded sides of the pronotum appar- ently narrower than in the allied species, surpassing the head by about one-half the width of the latter, the marginal spines shorter and black only at their extreme tips. The closed elytra more narrowed posteriorly, their discoidal area almost completely elevated in a large subglobular cyst which is more elevated than the median carina of the pronotum. Body beneath deep black with the legs and antenne pale; smooth por- tion of the pronotum and elytral markings fuscous brown, rather paler than in juglandis, the expanded areas whitish hyaline with the nervures soiled white; dorsal aspect of the pronotal hood brown, with the center of the large areoles paler; expanded sides of the pronotum with a faint irregular brown cloud exteriorly before the middle and sometimes a trace posteriorly. Elytra with a broad brown crescent following the humeral margin and usually attaining the discoidal area within, thus leaving a clear spot at the inner anterior angle of the costal area; tumid disk of Vor. VIT] GIFFARD—CALIFORNIA HEMIPTERA 259 the discoidal area brown from before the middle; apex of the elytra with a broad transverse band omitting the marginal areoles and connect- ing with a longitudinal cloud on the overlapping sutural areas; pronotal carina white with the usual fuscous vitta. Described from numerous examples taken about San Diego during May, July, October and November, and three exam- ples taken by Mr. Giffard at Los Altos, July 26, 1916. This form may best be distinguished by its having the dis- coidal cyst of the elytra large, covering most of the discoidal area. C. incurvata Uhl. is very similar to this but it ts smaller, has the discoidal bullz of the elytra smaller, the costa more deeply arcuated and the colors paler with the elytral vitte faint.

Physatocheila ornata, new species _ Form of brevirostris, a little broader than plexa; pale cinnamon varied with brown and buff; costal area with two series of irregular areoles. Length 4 mm. Antenne more slender than in any of our allied species, the third seg- ment apparently about one-half the thickness of the second, this latter two-thirds as long and as wide at apex as the first, much narrowed bas- ally; fourth clavate, distinctly longer than the first. Reflexed pronotal margins a little narrower than in plexa, leaving a wider area between the conspicuous carine, the surface as in brevirostris with a vague transverse line between the posterior angles of the reflexed margins behind which the areolz are distinctly larger; in plexa these larger areolz extend for- ward but about half way to the reflexed portion. Costal area with two rows of very irregular areola, these being more irregular than in plea. Tip of the rostrum covered in all the specimens before me but appar- ently attaining the apex of the metasternum and little if any surpassing it. Color yellowish or more or less fulvous, the elytra and reflexed por- tion of the pronotum cinerous-white; head black with the spine-like 260 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. carine white, the surface closely and minutely pale pubescent, omitting a line either side next the lateral carine; the prominent tylus pale; buc- cule large, white, becoming infuscated at apex. Antenne and legs fulvo- testaceous, the fourth antennal segment black on its apical two-thirds. Femora and tibie with an obscure dark median cloud, tarsi fuscous. Rostrum pale, darker at apex. Pronotum deeper fulvous on its disk, paler anteriorly and posteriorly, marked with fuscous in the anterior im- pressions; carine white, the median marked with black on the crest and near the tip, the lateral with a fuscous mark behind .the middle and some- times another on the crest. Closed elytra with a common large, nearly round, brown cloud on their disk, darker anteriorly; the veins on the reflexed sides of the pronotum, on the costal area and on the apex of the sutural area and membrane mostly fuscous or black, the disk of the mem- brane with a few vermiculate fuscous lines; extreme base of the discoidal area infuscated.

Phytocoris vinaceus, new species Aspect of rufus, but much larger and proportionately more slender; smaller and broader than roseus; deep wine red, eyes, membrane and sometimes the hind margin of the pronotum black or nearly so, the an- tenn faintly banded with pale. Length to tip of membrane 5 mm. Head nearly vertical, face flattened above where the longitudinal fur- row is distinct, below prominently convex; clypeus and lower cheeks also prominent. Antenne slender, as long as the body; first segment nearly linear, as long as the width of the pronotum; second not quite twice as long as the first and about half as thick; third still more slender and about two-thirds the length of the second; fourth about two-thirds the length of the third. Pronotum longer than in rufus, twice as wide as long, sides a little concave, callosities prominent. Elytra parallel, the abdomen reaching the middle of the cuneus in the male, nearly to its tip in the female; surface moderately polished, sparsely clothed with very short fuscous ae Rostrum passing the middle of the abdomen. Legs about as in tibialis. Color a nearly uniform dark wine red, sometimes a little paler be- neath, on the anterior disk of the pronotum and on the cuneus, the pro- notum usually shading to fuscous or almost black at the hind margin, which is very slenderly paler. Membrane nearly black, immaculate, the nervures mostly red. Abdomen more or less infuscated in the male and in the region of the oviduct in the female. Femora sometimes darker toward their apex, and, with the tibia, faintly dotted with pale; tibial bristles pale and little longer than the thickness of the joint. First seg- ment of the antenne sparsely dotted with pale, the pale bristles a little longer than the thickness of the segment; second and third segments with a narrow whitish annulus at base and a broader one just beyond their middle; these segments and the fourth sometimes infuscated. Described from five examples taken by me at Hoberg’s Resort, August 2, 1916, and four taken by Mr. Giffard the next day near the road to Lakeport, all on manzanita. Mr. Giffard also took this species from manzanita in Sonoma Valley on August 3, 1916, and again in Placer Co. and at Tahoe at an altitude of 3900 feet. Mr. Fordyce Grinnell has sent me one example taken by him at Pasadena, June 5, 1910. At Hoberg’s Resort we found the young in abund- ance, but few had then reached maturity.

In one example the callosities are black and another has the pronotum entirely red and the black vitta on the elytra so reduced that it covers only a portion of the clavus and a small spot on the inner angle of the corium. Described from two male and two female examples taken by Mr. Giffard at Seattle, Wash., July 7, 1917. I would be inclined to consider this a deeply colored form of rapidus were it not that the rostrum reaches only to the apex of the middle coxz instead of past the posterior. In three examples the tip of the cuneus is black. It is possible that both this and superbus are geographical races or subspecies of rapidus.

Elytra strongly convex, coarsely, deeply punctate; embolium broad at base but soon becoming confused with the swollen posterior disk. Scutellum strongly convex, polished. Sinistral genital hook of the male with a long distal horn. Color yellowish testaceous, sometimes tinged with carneous, clouded with piceous brown and strongly punctured with brown. Face fulvous brown, normally with the base of the vertex, a median line and the cly- peus pale, the latter with a geminate brown line on its basal one-half, the sutures of the cheeks slenderly piceous. Pronotum with the collum broad and strongly arcuate, polished; a large spot on the callosites and some- times the disk posteriorly black; hind edge slenderly pale, the median line more or less distinctly pale. Scutellum polished black, the basal angles, apex and median line usually pale. Elytra with a spot at base, a large one on the middle and the apex broadly piceous. These marks or at least the basal may become obsolete or almost confluent. Cuneus pale or carneous, the immediate base and broad apex black. Membrane fulig- inous, darker at base, with a faintly paler spot at tip of the cuneus, which may become a transverse band. Beneath more or less sanguineous, paler on the coxe and often becoming piceous on the abdomen, the sides of the venter in pale examples being marked with a row of piceous spots. An- tenne pale, the thickened apex of the second segment black and there may be a dusky annulus near the base of this segment.

Length 4-5 mm. Head as in californicus. Pronotum with the humeri less prominent and the hind margin but feebly excavated before the scutellum. Elytra about as in the allied species. Antenne a little longer; second segment as long as from the tip of the head to the incised line on the scutellum; third considerably longer than the second; fourth short, one-third longer than the first. Rostrum reaching to between the intermediate coxe. Color sanguineous or black. Head and pronotum black, polished; scu- tellum and abdomen sanguineous to piceous. Elytra yellowish-subhyaline, in certain lights showing a deep purple reflection from the wings beneath; costal nervure slenderly brown and against it a slender brown line, widened to its apex and reaching to opposite the tip of the clavus; apex of the corium broadly black, the cuneus more opaque, yellowish white with the broad apex black; a sanguineous line follows the claval suture and is deflexed around the apex of the corium. Membrane slightly enfumed with a deeper shade beyond the areole, the nervures fuscous. Coxe and legs yel- lowish, the femora more or less castaneous, and the hind tibie nearly black. Antennz pale yellowish, the first segment and base of the second deep black. Rostrum pale, becoming black at base and apex. Described from two females taken by Mr. Giffard at Wa- wona, June 17, 1916, and one female taken by me at Alpine, San Diego Co., June 7, 1913.

Head longer than in agilis, the neck behind the eye equal to the length of the eye when viewed from above. Antenne reaching to about the apex of the cuneus; first segment about as long as the space between the eyes; second as long as the head and pronotum together; third rather longer than the second; fourth about one-half the third. Pronotum as in agilis, longer with the sides more strongly sinuated than in californicus. Elytra long and narrow, parallel. Basal segment of the rostrum scarcely surpass- ing the hind margin of the eyes, in agilis attaining the base of the head. Color black, polished. Head entirely black, the vertex and neck highly polished. Pronotum black, the disk triangularly pale yellowish, this pale mark resting on the hind margin; collum white. Scutellum opaque black, the basal angles of the basal field often pale as are occasionally those of the apical field. Elytra pale yellowish, becoming whitish along the costa and on the cuneus, the disk with metallic reflections from the iridescent wings beneath; apical half of the clavus and inner field of the corium infuscated; apex of the corium with a black vitta which does not quite attain the costa. Membrane hyaline with a broad mediam longitudinal fuscous vitta, the nervures heavily fuscous except at apex. Rostrum pale, the basal half of the first segment and the apex black. Legs pale yellowish, the posterior femora and sometimes the anterior and intermediate, with a longitudinal row of fuscous points; extreme base of the tibiz and the apex of the tarsi blackish. Abdomen black in the male, pale yellowish or greenish in the female, becoming black at base and along the sides. Antennz pale testace- ous clothed with a pale pubescence; second segment and base of the third black; first white, black at base. Described from one male and six female examples taken by Mr. Giffard in Muir Woods, July 15, 1917. The dorsal fuscous vitta on the elytra is sometimes tinged with red, sug- gesting californicus. The longer head and antennz will dis- tinguish this from both californicus and agilis. The former is a broader insect with the membrane mostly black and the basal segment of the antennz and the base of the second black and the elytra red at apex and along the commissure, while agilis has the basal antennal segment entirely pale, the tip of the corium with a black mark resting on the costa and extending but little along its apex, and the membrane quite uniformly but lightly enfumed with the areoles hyaline.

Vertex with a linear depression before the slender basal carina, before swollen about as in robinie. Antenne a little shorter than in the allied species; second segment nearly as long as the head, pronotum and scu- tellum together, considerably longer than the basal width of the prono- tum; third one-half the length of the second. Pronotum one-half as long as its basal width, in robinie two-thirds as long, angulate transverse de- pression before the callosities, reaching almost to the inner angle of the eyes, in robini@ much shorter, with the callosities prominent and rounded within, while in aculeata they are more elongated, oblique and less convex toward the median line than in robinie; surface posteriorly a little more convex than in the allied species; sides slightly concave with the carinate edge more obtuse. Elytra narrow, the costa but very feebly arcuated; sur- face almost smooth, obscurely wrinkled on the clavus, clothed as is the pronotum, with scattering short black hairs, which want the black dots at their base. Dextral hook of the male genitalia broad, ligulate, incurved, pale, broadly rounded or almost truncate at apex; produced just before its dorsal apical angle in a long acute, curved process which is serrated be- Ze, CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. hind and meets an obtuse tooth on the upper lateral margins of the py- gofers. Sinistral hook rather broad, curved and following the ventral wall of the pygofer, its apex not disclosed in any specimen before me but apparently obtuse. Color deep dull black. Venter in clearly marked examples with an elongated fulvous mark against each eye and an indistinct longitudinal median vitta, but generally these markings are more or less obsolete; cheeks sometimes obscure rufous. Pronotum pale yellowish, more or less tinged with fulvous or rufous, including the raised anterior margin; callo- sities and the area between them black, the disk posteriorly sometimes suffused with blackish. Closed elytra with a broad diffuse commissural vitta which usually fades out on the base of the clavus. Scutellum, mem- brane, legs, antenne and lower surface deep black, the disk and sides of the venter sometimes becoming reddish; apex of the dextral genital hook conspicuously pale.

Lopidea ampla, new species Closely allied to aculeata; larger with more conspicuous black hairs _ above and with the elytral costa distinctly bowing and different male geni- talia. Length 7-714 mm. Vertex flattened posteriorly with the basal carina sharp, not reaching the inner angle of the eyes. Antenne longer and stouter than in aculeata; the first segment distinctly longer and thicker; third about two-thirds the length of the second. Pronotum and callosities shaped as in aculeata. Elytra wider than in aculeata, the costa regularly and distinctly arcuated; width when closed 2 mm. at base and 214 mm. at widest point; clavus distinctly wrinkled or shagreened, giving the elytra a rougher aspect than in aculeata. Whole surface of insect rather closely clothed with stiff black hairs, which spring from punctures that are frequently fuscous or black; these hairs are especially long and thick on the head and pronotum and are much more conspicuous on the elytra than in aculeata. Dextral hook of the male genitalia broad, a little constricted before the rounded depressed apex; this flattened apex is sometimes paler in color and may have its superior angle slightly produced; the tooth-like dorsal projection on the dextral margin of the pygofer is shorter and more obtuse than in aculeata. Sinistral hook broad and curved, its apex ex- panded, bifurcated and somewhat twisted. Color deep opaque black; posterior one-half of the pronotum, including the depressed sides, and broad costal margin of the elytra, yellowish tes- taceous; narrow hind edge of the pronotum and sometimes its median line fuscous; hind edge of the ventral segments narrowly whitish. Described from numerous specimens representing both sexes taken by Mr. Giffard on Vicia gigantea at Lands End, San Francisco, July 24, 1917; and a good series from Seattle, Wash., taken July 7, 1917.

Head clearer yellow, clypeus narrowly fuscous, the buccule whitish. Disk of the pronotum in- fuscated behind the black callosities and marked with fuscous dots at the base of the black hairs with which the surface is clothed and with an obscurely paler median line. Basal area of the scutellum with a yel- low mark on either side. Clavus as in lineolatus, not entirely black, dotted with fuscous; corium sparsely dotted with black, especially on its posterior disk; costal nervure, a narrow longitudinal median vitta and the hind edge blackish. In essigi the corium is yellow with a slender costal line and the broad apex black and the disk with black hairs which do not spring from black dots as they do in intermedius and lineolatus. Cuneus immaculate except for an obscurely blackish costal line. Membrane as in essigi, deeply infuscated with the nervures yellow and a white mark next to the apex’ of the cuneus followed by a blackish ray. In J/ineolatus the membrane is less deeply infuscated, leaving the black ray more conspicu- ous. Legs obscure greenish lineate with fuscous and with the usual pale dots at the apex of the femora as in both allied forms. Antenne black or nearly so, with the base of the second and third segments very nar- rowly pale.

Head shorter and more vertical than in ornatus. Vertex smooth, but slightly convex; clypeus narrow, prominent; facial angle less than a right angle. Antenne about as in ornatus; first segment exceeding the clypeus by one-fourth its length; second stout, not thinner than the first, in the male nearly as long as the basal width of the pronotum, in the female shorter; third and fourth together as long as the second; third one-fourth longer than the fourth. Pronotum shorter than in ornatus; moderately convex, the anterior angles well rounded, sides regularly arcuated, hind margin very feebly excavated; callosities subcontiguous. Tumid base of the scutellum well exposed; apical lobe almost flat. Elytra oblong, nearly flat, the costa but feebly arcuated; abdomen of the male attaining the apex of the cuneus, of the female reaching to apical one-fourth of the membrane.

Described from one male taken by me at Tallac, July 25, 1915, and a female taken by Mr. Giffard in Niles Canyon in May, 1916. This female has a decidedly fulvous tinge and the basal lobe of the scutellum is bright fulvous and it may rep- resent a distinct species. The shorter and more convex pro- notum and less produced head make this species aberrant in this genus. It should perhaps go in Phylus but the male geni- tal segment certainly is not carinate.

Rostrum reaching nearly or quite to the base of the venter; first ‘joint just attain- ing the base of the head. Antenne rather short; first segment but little surpassing the tip of the clypeus; second about as long as the basal width of the pronotum, in the male cylindrical, as thick as the first; in the female slender; third and fourth slender; third two-fifths the length of the second; fourth three-fourths of the third. Pronotum proportionately shorter and broader than in either of the other species, much shorter than the scutellum, scarcely longer than the head when viewed at right angles to the plane of the latter; its length about two-thirds its basal width; an- terior angles well rounded; posterior margin straight, leaving the base of the scutellum broadly exposed; callosities small, scarcely discernible; an- terior margin broadly flattened; upper surface rather sparsely clothed with pale hairs. Color pale greenish white. Face more or less strongly tinged with fulvous and showing a pale basal mark and median longitudinal line. Pro- notum, scutellum and elytra irregularly and not very densely dotted with olive or fulvous brown; these dots are coarser than in the allied species and tend to form rings enclosing pale areas; on the pronotum they are 280 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. fewer and more yellowish and may be nearly or quite wanting in immature individuals. Membrane closely irrorate with pale brown beyond the are- oles, which are faintly clouded with smoky at apex, with the nervures whitish; at the apex of the cuneus is a whitish spot followed by a trans- verse pale fuscous vitta. Antennz and legs concolorous, greenish white, the hind femora more or less dotted with brown toward their apex; hind tibia with about seven large black points, each carrying a pair of stout black bristles; the anterior and intermediate tibize with fewer black bris- tles and but indistinctly dotted; tarsal claws brown.

Plagiognathus mundus, new species More polished and clearly marked than obscurus; femora black; cuneus black with its margins more or less broadly pale. Length 4-5 mm. Head more produced than in obscurus; when viewed from the side its length below the eye is fully equal to the length of the eye, while in obscurus it is distinctly less. Antenne, pronotum, scutellum and elytra as in the allied species; second antennal segment as long as the basal width of the pronotum; third and fourth slender; third two-thirds the length of the second; fourth one-half the third. Pronotum trapezoidal, much narrowed anteriorly, sides rectilinear; callosities inconspicuous. Elytra almost parallel, a little wider posteriorly, its greatest width in the male at apex of the corium; sides rectilinear in the male, but little arcuated in the female. Rostrum attaining the apex of the hind coxe. Color black, polished, marked with pale greenish or yellowish. Vertex with a greenish spot, which is broader than in obscurus and often is ex- tended so as to cover much of the surface as in that species. Antennz black with the apical two segments pale. Pronotum black, only in the palest specimens with the disk posteriorly greenish. Scutellum black, rarely with the posterior field greenish in whole or in part. Elytra black, normally marked as in obscurus with a pale area at base which may be extended along the claval suture and discal nervure and very rarely along the costa; tip of the clavus and the commissure beyond usually touched with pale; cuneus black with its margins more or less broadly pale, the black at times reduced to a small median spot or the pale may be reduced to a mere trace on the base and tip. In obscurus the apex is black with the base more or less broadly pale. Membrane black; the nervures usu- ally pale, especially at apex, where there may be a pale spot adjoining. Beneath black; hind edge of the propleura, apex of the coxz and base of the femora greenish. Tibize whitish, coarsely dotted with black; tarsi black, the second segment mostly pale, the tips of the femora usually pale. Rostrum black. Described from numerous examples taken by Mr. Giffard at Niles Canyon, June 13, 1917, and Contra Costa Co., June 14, 1917. This species varies in the extent of its pale mark- ings as does obscurus but may be distinguished by the black femora and by its having the cuneus black on its middle and 232 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. not at apex. Pale examples may become a clear light fulvous on the pale areas. In dark examples the elytra may be en- tirely black excepting a touch of pale at base and apex of the cuneus and on the membrane at apex of the areole. In fresh specimens the body is clothed with a pale pubescence. The Niles Canyon specimens have the pale markings more extended than in those from Contra Costa Co. At Portland, Oreg., and Seattle, Wash., Mr. Giffard took a series that show the same variation in color but differ in having the tibiz more or less obscured, sometimes entirely blackish. In teneral examples the hind femora are pale enough to show the black dotting characteristic of the genus.

Plagiognathus lineatus, new species Very near mundus but having the elytral costa a little arcuated in both sexes and marked with a pale vitta within the costa and a more slen- der line on the claval suture. Length 5 mm. All structural characters in this species seem to be identical with those found in mundus, except that the costa is gently arcuated in the male as well as in the female and widest a little before the middle, a character that might come from the shortening of the elytra found in this species. Color blackish fuscous, clothed with a rather close pale pubescence. Base of the vertex with a transverse pale vitta, which shows no tendency to spread over the vertex in the specimens before me. Pronotum some- times with a pale area before the callosities and a larger one on the disk behind them. Elytra with a narrow pale vitta on the claval suture, con- tinued on the commissure, and a wider one just within the costa, the latter connecting with the pale on the cuneus. Membrane deeply infuscated with the nervures pale and with a whitish spot against the apex of the cuneus, covering much of the smaller areole. Coxe in great part and often the base of the femora pale. Legs black with pale knees, in some examples with the tibia more or less distinctly pale and marked with black dots. Described from five male and two female examples taken by Mr. Giffard at Portland and Seattle, July 3-7, 1917.

Plagiognathus diversus, new species Allied to politus; black, anterior and intermediate femora pale; tibiz strongly dotted; corium often pale at base; base of cuneus broadly white. Length 3% -4% mm. Head broad and short, projecting beyond the eye for less than the length of the eye. Vertex distinctly convex, its base apparently angled, this angle fitting into a shallow emargination of the pronotum; facial angle almost a right angle. Pronotum transverse, a little longer, with the rectilinear sides more oblique in the male. Elytra subopaque; long and nearly parallel in the male, the abdomen attaining the middle of the cun- eus; shorter and more ovate in the female, with the abdomen reaching to beyond the tip of the cuneus. Rostrum reaching to the apex of the intermediate coxe. Hind femora broad, especially in the female. Color black; base of the vertex with an oval pale spot against each eye, sometimes almost obsolete; third and fourth antennal segments and apex of the second pale. Pronotum sometimes touched with pale poste- riorly; clavus at times pale at base; corium usually in the female, some- times in the male, with a pale. area which may be extended down the claval suture and along the costa, the commissural nervure pale beyond the tip of the clavus. Base of the cuneus with a broad whitish lunule, its apical margin sometimes touched with pale. Membrane blackish, ob- scurely edged with pale at base, especially at apex of the cuneus, the ner- vures concolorous, becoming pale at apex. Beneath black, the coxe pale beyond their base. Anterior and often the intermediate femora pale; hind femora black; all the tibiz white dotted with black and armed with black spines. Tarsi black on apical one-half, obscurely pale at base.

Plagiognathus diversus cruralis, new variety Differs from the species in having the legs darkened so the anterior and intermediate femora are black or nearly so and the tibie are fuscous or black, thus obliterating the black points. The pale points on the vertex are scarcely discernible and the antenne are almost entirely black. One structural difference appears here: the second segment of the antenne is distinctly thicker than in the species, but in all other characters the forms intergrade and it does not seem advisable to establish this as a new species. 284 CALIFORNIA ACADEMY OF SCIENCES (Proc. 47H Ser.

Excentricus californicus, new species Smaller than the European species; black, above clothed with white scale-like hairs and pale pubescence; basal two segments of antenna much thickened in the female. Length 3 mm. Female: Head long, subrostrate, but moderately deflexed or sub-por- rect. Vertex but gently arcuated, its base ecarinate. Clypeus narrow, prominent, bent so its apex becomes nearly vertical, but little exceeding the cheeks, its basal suture distinct, a little anterior to the insertion of the antenne; facial angle almost a right angle; gula nearly horizontal. Antenne stout; basal segment strongly clavate, its apical thickness nearly one-half its length, exceeding the clypeus by one-fourth its length; second segment fusiform about as long as the basal, as thick at its middle as the diameter of the eye viewed from before; both these segments clothed with fine appressed black hairs; third and fourth very slender, together as long as the second; third a little longer than the fourth. Pronotum trapezoidal, its margins nearly rectilinear, the sides curving a little to the Vou. VII] GIFFARD—CALIFORNIA HEMIPTERA 285 anterior angles which nearly attain the outer line of the eyes; callosities hardly distinguished. Elytra somewhat expanded apically, the cuneus short with a deep fracture. Membrane short, but little exceeding the ab- domen with a distinct notch at apex of the cuneus. Hind femora mod- erately incrassate; third segment of hind tarsai subequal to the second. the first shorter; claws small, strongly incurved; arolia apparently wanting. Color piceous black; cuneal fracture and narrow apex whitish; apical two antennal segments, rostrum, except at apex, apical two-thirds of tibie and the basal two segments of the tarsi testaceous; tibial spines and a dot at their base black. Eyes brown. Upper surface and pleurae clothed with pale pubescence and intermixed deciduous thicker white hairs. Mem- brane fuscous, with a pale lunule at the apex of the cuneus and a large pale spot on its middle, spreading more or less over the basal field; the nervures heavy, fuscous. Described from two females taken by Mr. Giffard in Placer Co., at 6000 feet, August 20, 1916. The form of the female antennz and the less produced head exclude this species from Criocoris while from Atracto- tomus it may be distinguished by the thickened basal segment of the antennz and the form of the head and pronotum. It seems to be near the European Excentricus punctipes but 1s much smaller and apparently has no black hairs among the pale ones on the upper surface.

An immature unarmed specimen of var. quadrivittata Say was taken at Wawona with the typical form. 198. Platycotis maritimus, new species Intermediate between vittata and minax, but more closely related to the former; pronotum unarmed in all individuals seen by me; greenish or brownish, more or less varied with darker, median carina black in part. Length to tip of elytra 8 mm. Head nearly as in vittata, the anterior margin more evenly arcuated and distinctly reflexed than in the allied form; surface distinctly wrinkled vertically with prominent percurrent median carina. Pronotum similar to that of wittata, with finer, distinct punctures; median carina attaining the anterior margin; cicatrices distinctly smaller and shorter than in vittata, beginning abruptly about two-thirds their own length from the median carina and terminating just beyond the inner line of the eyes. In vittata they end indefinitely very near the median carina and extend lat- erally fully to the middle of the eyes; humeri prominent and obtuse; apex usually acute, attaining the middle of the inner apical areole. Elytra hya- line, with strong brown nervures, barely touched with smoky at apex beyond the apical nervure. Last ventral segment of the female deeply roundedly excavated almost to its base; plates of the male subterete, par- allel and approximate, reaching distinctly beyond the tumid sides. of the pygofers, which in this species are much expanded.

Costa and base of the clavus yellow, the former often reduced to a mark on the base of the outer discal areole. Beneath pale testaceous, the tibie and tarsi more or less embrowned. Described from four males taken by me on tan-bark oak in Muir Woods, September 5, 1914, and three males and two females taken by Mr. Giffard at the same locality, August 16, 1916. One male from Departure Bay, Vanc. Isd., August 8, 1913, shows the vittze found in vittata but the lateral are more curved, connecting with the longitudinal vitte at one end and with the humeral spot at the other. The characters given for this species seem to be constant, but wider collecting may show that it is but a phase of vitiata inhabiting the fog belt along the coast.

VII] GIFFARD—CALIFORNIA HEMIPTERA 291 223. Oncopsis californicus, new species Allied to pruni, but larger, with the median line of the pronotum dark, accentuated by a paler area either side; last ventral segment of the female short, triangular, with an apical notch; elytra hyaline, with heavy fuscous veins, at least in the male. Length 5-514 mm. Head regularly rounded, the vertex of equal length across its whole width, and with the disk of the front, strongly punctured. Pronotal ruge, carrying scattering punctures, more distinct than in variabilis, these ruge more regular and less interrupted than in pruni; middle of the vertex, with a longitudinal carina, usually obvious. Elytra with three ante-apical areoles, the outer sometimes broken up in the male, the nervures strong; areoles mostly hyaline, sometimes more or less clouded toward the claval suture in the female. Last ventral segment of the female short-triangular, with a rather deep elliptical or linear notch; oviduct surpassing the py- gofers farther than in the allied species. Color pale testaceous varying to greenish or yellowish, varied with cinerous or fuscous. Base of the vertex with a black dot either side placed a little nearer the eye than to the median line, these dots usually con- nected by an irregular fuscous band, which in the male may send a me- dian branch to the base of the front. Face with a transverse arcuate black band on the base of the front and sometimes a smaller one at apex, either side with a broad fuscous arc; most individuals also have a black point at each ocellus. Pronotum typically fuscous or black in the male, with a transverse pale area behind the cicatrices vaguely extended to the hind margin either side of a dark median line, the transverse band usually including one or two black points behind each eye. Scutellum blackish, with the basal angles and an oblique line either side of the middle pale, the latter ending in a yellow spot on the basal angles of the apical field. Elytra whitish hyaline, the nervures heavy and fuscous, the commissural twice interrupted with pale. In the female the black becomes brown or cinnamon, with the pale marks much extended and the élytral nervures scarcely infuscated. Described from a series of both sexes taken by Mr. Giffard near the Tunnel Road east of Berkeley, May 13, 1917, and at Niles Canyon, May 23, 1917. What seems to be a pale variety of this species is cinna- mon-brown with the elytra clouded toward the claval suture, the clavus pale and the nervures scarcely darker. This form was taken at Tahoe, August 23, 1916, and at Niles Canyon in May, 1916, and seems in a measure to connect californicus with variegatus, which has similar genital characters. Were it not for the very different character of the males, which closely resemble those of pruni, they might be considered as races of one species. This form may be distinguished super- ficially by the dark median line on the pronotum.

Head wider than the pronotum, rounded in both diameters in both sexes. Vertex nearly right angled before, the apex subacute; hind margin broadly arcuated, middle line a little elevated, with an oval slightly de- pressed area either side next the base; surface closely and evenly punc- tured. Front broad and short, moderately convex, closely minutely punc- tured; clypeus broad, oblong, its sides very slightly concave, attaining the apex of the cheeks. Pronotum a little shorter than the vertex, distinctly, transversely wrinkled; anterior and posterior margins nearly parallel. Elytra short, oblong, hardly attaining the apex of the abdomen in the female, but little surpassing it in the male; costa gently arcuated, apex rounded.

Wings rudimentary, about half the length of the elytra. Last ventral segment rather long, its apical margin broadly rounded and a little notched at the middle. Color pale green, tinged with yellow on the head, the abdomen more or less fulvous; superior genital segment sometimes marked with black at base; the ovi- duct brown. Male more whitish and clothed with a white bloom; vertex and prono- tum with two slightly diverging broken fuscous vitte forming two pairs of spots on the vertex. Tergum mostly black; inner surface of the ante- rior and intermediate tibiz, apex of the tarsi, a spot on either side of the pygofers at base and the tips of the plates black. Elytra in this sex attain- ing the tip of the abdomen. Valve wanting; plates linear, long, curved upward and somewhat surpassing the anal tube. Described from one male and seven female examples taken sby Mr. Giffard at Lands End and Golden Gate Park, San Francisco, in June and July and in San Mateo Co. in June.

Thamnotettix montanus reductus, new variety This form seems to be purely a color variety in which the yellow saddle is reduced to a small mark on the apex of the claval nervures, often on the outer nervure only, or in a few dark males it may be entirely wanting. The brown band on the base of the vertex is also reduced, sometimes to a mere shade, but there may be a dark line next the eye and a gem- inate spot on the basal middle. Both forms are found to- gether throughout their range, but the present form is much more abundant toward the south, while those from Oregon and Washington are almost entirely typical montanus.

In this species, as I have here identified it, the vertex is decidedly, almost acutely, angled; the color is smoky brown with the vertex and scutellum often paler or almost yellow, and the apex of the two claval nervures are pale. The elytra become smoky-hyaline toward the costa and the lower surface is paler, becoming pale yellow in some individuals from near the coast. The last ventral segment of the female is excavated for about half its width with a ligulate median tooth which attains the line of the lateral angles. My original description must have been drawn up from an immature example, as some immature specimens before me agree exactly with it. This species may best be distinguished from flavocapitatus by its longer and more acute vertex. Vor. VII] GIFFARD—CALIFORNIA HEMIPTERA 299 277. Thanmotettix flavocapitatus Van D.

Vertex acutely right-angled, nearly two times as long on the middle as next the eye. Front long and narrow, sides gradually approaching, a little more abruptly near the apex; clypeus a little widened to the rounded apex. Pronotum one-fourth longer than the vertex. Elytra as in gemi- nata, the costa gently curved. Color yellow. Vertex and front tinged with fulvous, the base of the former pale; frontal arcs faint, brown. Pronotum tinged with green. Elytra hyaline, a little obscured at apex, the nervures strong, greenish yellow, becoming fuscous about the apical areoles. Abdomen and breast black with the margins of the segments yellow. Legs whitish, the spines of the hind tibiz set in black dots; genital pieces white. Last ventral segment of the female deeply broadly excavated with a ligulate median tooth nearly equalling the lateral angles. Valve of the male short, rounded; plates small, long-triangular, subacute at apex, the sides fringed with long white hairs; pygofers not exceeding the plates. Described from one pair taken by Mr. Giffard on Mt. Tamalpais in August, 1916, and one female taken by me at Hoberg’s Resort, Lake Co., August 2, 1916.

VII] GIFFARD—CALIFORNIA HEMIPTERA 303 Color of body yellowish to dark greenish in places in the female; the apex of the tibie and the tarsi often of a bluish green. In strongly col- ored examples the front shows a broad whitish median longitudinal vitta and base, and on the vertex a whitish band next the eyes, a narrower longitudinal one on the middle and an oblique transverse one either side at apex. Pronotum with three white spots on the anterior margin, the median often continued as a fainter median vitta to the apex of the scu- tellum. Elytra uniformly milky-hyaline, scarcely tinged with dull green in the female, not at all in the male, the commissural and sutural nervures of the clavus slenderly fuscous. Apex of the elytra with a smoky cloud in the female which may cover much of the surface in the male. Wings milky- hyaline with fuscous nervures. Abdomen blackish in the male, narrowly margined with yellow, dull green in the female. Described from six male and seventeen female examples taken by Mr. Giffard at Summit, Placer Co., August 24, 1916, at 7000 feet elevation. Immature examples of smaragdula show indications of the white marks on the head and pro- notum and they sometimes are absent in the females of this species, but the elytral characters are constant in sublactea and the male genital characters are obviously distinct. That this type material is mature is evident by the presence of the pruinose spots on the elytral costa in some males. Holotype (No. 369), male, in collection of the California Academy of Sciences.

Empoasca transversa, new species Aspect of a small dark aureoviridis; dark greenish, elytra bifasciate with dusky. Length 4% -5 mm. Head with the eyes distinctly broader than the pronotum. Vertex shorter and broader than in trifasciata. Hind margin of the pronotum moderately concave, nearly truncate in ftrifasciata. Last ventral segment of the female considerably produced, the sides moderately sinuated, much as in aureoviridis; in trifasciata shorter with the sides scarcely sinuated. Twisted apex of the male plates very broad, membranous, almost spatulate. Pygofers distorted in the specimen before me, but apparently produced as in aureoviridis. Color dark dull green, becoming blue green on the legs, apex of the abdomen and extreme base of the costa. Face and vertex marked with white as in sublactea and aureoviridis. Anterior margin of the pronotum with three white spots, usually distinct, the intermediate produced in a median pale line which may cross the scutellum. FElytra with a faint transverse fuscous band crossing the middle of the clavus and another on the apical areoles, neither attaining the costa, the apical beginning at the tip of the clavus and interrupted by the pale nervures. Tergum inclined to golden green. Described from one male taken by Dr. J. C.

This may prove to be a maculated variety of aureoviridis but that seems very unlikely. Empoasca tn- fasciata is a little smaller with a more prominent head. It is yellow rather than green, and has three well-defined trans- verse fuscous bands, the first of which, covering the poste- rior portion of the pronotum, is not indicated in this new species, and the apical is shorter, beginning very little before the transverse nervures and has all the contained nervures concolorous, whereas in transversa they are pale within this posterior band.

Elytra with five apical areoles, the second triangular and pedunculate. Last ventral segment of the female rather strongly pro- duced with its apical margin entire. Male plates triangular, the sides nearly rectilinear to the subacute tips. Color yellowish-green, the tibie becoming blue at apex. Vertex some- times tinged with orange, with a paler spot on either side, often with a darker mark either side of a pale median line; base of front marked with a pale dot at apex placed in a square of four similar dots and usually there are two others on either side; apex with a pale median vitta ; cheeks with about three elongated pale marks. Pronotum and scutellum san- guineous-brown, the former with three conspicuous whitish spots on the anterior margin, the latter with a darker spot at each angle and a median transverse row of three pale points just below the incised line. Elytra subhyaline, irregularly mottled with yellowish, the tip of the clavus with a conspicuous rufous-brown spot; apex, from a little before the transverse nervures, deeply infuscated, with strong pale nervures. Abdomen often pale yellow at base and green at apex. Described from thirty specimens taken by Mr. Giffard at Los Altos, July 26, 1916, on pitcher-sage (Sphacele colycina ), and at Westpoint on Mt.

Catonia clara, new species Allied to fusca and irrorata, but easily distinguished by the single black band on the front; fuscous, elytra dotted with white, the carine of the vertex and notum pale, bordered with fuscous. Length 4% -5 mm. Vertex distinctly transverse, a little longer than in irrorata but shorter than in fusca; carine distinct; front convex as in fusca. Pronotum short and deeply emarginate as in the allied species. Elytral neuration similar to that of fusca, the outer sector forked distinctly in advance of the inner. Color pale testaceous, the elytra fuscous with pale nervures, the are- oles marked by a row of short white transverse veinlets along the lon- gitudinal nurvures excepting the costal, becoming fewer on the membrane; the costal areole paler with three or four transverse fuscous clouds; carine of the vertex, pro- and mesonotum pale, bordered with fuscous lines; sides of the pronotum with about three fuscous areoles behind the eyes. Front pallid, tinged with yellow on its base, marked with a piceous band at apex and a row of about six fuscous points next each lateral carina. Clypeus tinged with yellow and faintly embrowned at apex. Pec- tus and legs testaceous, faintly clouded with fuscous. Abdomen fuscous, becoming almost black in the male.

Catonia albicosta, new species Allied to costata and succinea and intermediate between these species but with the broad front of the former; fulvo-ferruginous, costal area clear white as far as the stigma. Length 5% mm. Vout. VII] GIFFARD—CALIFORNIA HEMIPTERA 307 Vertex distinctly transverse, proportionately shorter than in costata; carine sharp, forming a somewhat acute angle before. Front broad, con- vex in both diameters, scarcely wider below; the median carina slender but evident. Clypeus convex, its median carina nearly obsolete except at base, the lateral broad, horizontal. Pronotum about two-thirds the length of the vertex, deeply angularly emarginate behind as in costata. Mesonotum as in the allied forms, the lateral carine approaching but lit- tle anteriorly. Elytra intermediate in length between the two species men- tioned, the transverse costal nervures obscure beyond the stigma. Color fulvous-brown, polished, darker than in succinea; head, pro- notum, patagie and legs paler fulvo-testaceous; clypeus, pleural pieces and legs pale fulvous; costal areole of the elytra white as far as the stigma; nervures concolorous; abdomen darker; apical teeth of the hind tibiz and tarsi blackish as in succinea. Described from twelve examples representing both sexes, taken on manzanita at Fallen Leaf Lake by Mr. Giffard on August 21, 1916. This interesting addition to our fulgorid fauna most closely resembles succinea but its shorter vertex, smaller size, darker color and especially the white costa will distinguish it.

Catonia succinea Van D. Fallen Leaf Lake, August 21, 1916. This species seems to be most abundant in July. 327. Oliarus hesperius, new species Very near aridus Ball but differing markedly in the male genitalia ; black with pale carine; disk of the mesonotum castaneous; front black with pale carine and a conspicuous white spot at apex of the frontal com- partments either side of the base of the clypeus. Length 6-8 mm. Vertex nearly square, its length and breadth subequal, its transverse carina obtusely angled or almost rounded, leaving a rather broad apical compartment; front much expanded, its lateral angles rounded. Prono- tum deeply, angularly emarginate; intermediate mesonotal carine abbre- viated before and behind. Elytral nervures strongly granulate and seti- gerous, the outer sector forked a little behind the inner. Male pygofers shorter than in aridus, the ventral notch wide with its sides diverging more than in that species, the lateral margins rounded behind and wanting the large notch at the dorsal angle found in aridus; dorsal surface not longer than the stiles, roundingly narrowed to the anal tube; stiles narrow, parallel, contiguous, subterete, their sagitate apical expansions cut out so as to leave the lateral extensions similar to the apical; in aridus this sagitate apex is broad-triangular with its apical margin scarcely if at all excavated, the apex of the stiles being much sur- passed by the elliptically produced dorsal surface. Color black or nearly so with the disk of the mesonotum castaneous between the lateral carine; carine of the head and pronotum slenderly 308 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4ru Srr, lined with pale; front and clypeus deep black, the former polished, the latter sometimes paler, the lateral white spots very distinct, oval, smaller and better defined than in aridus. Elytra whitish-hyaline; nervures white, becoming fuscous at apex, strongly dotted; the stigma large, fuscous, with its base white; female with fuscous spots at the forks of the sectors and on the transverse nervures. Described from a long series representing both sexes, taken about the bay district, the following localities being repre- sented in Mr. Giffard’s material: Los Altos, July 26, 1916; Redwood Canyon, July 2, 1916; Walnut Creek, August 10, 1916; and near Cloverdale, Sonoma Co., August 3, 1916. I have taken this species at San Francisco and Berkeley. This seems to be the most abundant species in the central coast region of California, while farther south it is replaced by californicus, which is equally abundant in San Diego Co. This is the species I had formerly determined as franciscanus, but a careful study convinces me that Stal’s species must be the complectus of Ball. 7 Holotype (No. 374), male, from Los Altos, in collection of the California Academy of Sciences. Allotype, female, from Los Altos, in collection of Mr. Giffard. Paratypes in both collections and in that of the author. 328. Oliarus exoptatus, new species Allied to californicus but with a broader vertex and heavier elytral venation; may be distinguished from aridus and hesperius by the absence of white spots at apex of the front. Length 51%4-7 mm. Vertex nearly square, a little broader than in hesperius; the anterior carina quite regularly arcuated. Front broad, intermediate in form between californicus and hesperius. Pronotum about as in hesperius, longer than in californicus; intermediate carine of the mesonotum strongly convergent and not abbreviated anteriorly. Elytral nervures heavy and maculated. Ventral notch of the male pygofers broad and shallow, its margins strongly oblique; sides of the pygofers short and broadly rounded, not surpassing the middle of the stiles; dorsal surface strongly produced either side of the anal tube and somewhat depressed at the apex of the lobes, considera- bly surpassing the stiles. Stiles slender, subterete, lyrate, diverging and again approaching at apex, their outer angles strongly produced in a long appendage which is curved upward and backward almost to the margin of the pygofer. Color deep black, the slender margins of the head and pronotum pale, those of the mesonotum concolorous or nearly so. Elytra whitish-hyaline, the nervures heavy, whitish but thickly and strongly granulate, giving them a blackish aspect; transverse veinlets carrying a fuscous line, the middle of the corium with an obsolete fuscous band; stigma large but broken by a white band; knees, tibiz and tarsi testaceous-brown.

This is a very common in- sect all over California. It varies much in size and color as well as in the darkening of the elytral nervures as does the eastern borealis; the genital characters are, however, suf- ficiently distinct. 334.

Aphelonema giffardi, new species Closely allied to histrionica; costal area of the elytra black; front en- tirely pale. Length 3-4 mm. Vertex as long as in histrionica, equalling the pronotum; the anterior margin more arcuated in the male. Elytra broader, the costal margin being more rounded. Last ventral segment of the female more narrowly and strongly produced, in histrionica entire with its apex minutely notched. Third ventral segment of the male much less deeply emarginate; inner margin of the male plates subangularly lobed, approximate at the middle 310 CALIFORNIA ACADEMY OF SCIENCES [Proc. 41H Szr. only; in histrionica obtusely rounded, with their inner margins nearly parallel or at most a little divergent dorsally. Color about as in histrionica; black varied with testaceous-white, but faintly tinged with yellow in places. Vertex, pro- and mesonotum with a broad white median vitta bordered either side by a heavy black line; lateral areas dusky with pale pustules and carine; discal area of the front entirely white, including the carine; lateral areas of the front black with a concentric row of about eight white pustules and a shorter row of four next the eye; clypeus black. Elytra reaching to near the apex of the third dorsal segment in the male, to apex of second in the female; whitish subhyaline, slightly infuscated on the broad clavus, the nervures inconspicu- ous; broad costal area black, bordered within by a clearer whitish ray. Abdomen black; tergum with three approximate broad white longitudinal vittee, the median bisected by a slender longitudinal carinate black line; sides exteriorly with two longitudinal rows of pale pustules placed on broken pale spots. Pleural pieces above and coxal region more or less whitish; apices of the femora, lines on the tibiz and basal three segments of the tarsi pale. Described from one female and two males, all brachypter- ous, taken by Mr. Giffard near Stockton in the San Joaquin Valley, May 25, 1917. It affords me pleasure to dedicate to Mr. Giffard this interesting addition to the fulgorid fauna of our state in recognition of the services he has rendered entomology by careful and systematic collecting of the Hem- iptera, both here and in the Hawaiian Islands.

Naethus maculatus fasciatus, new variety Differs from the species by having the elytra marked by a continuous broad brown band from the inner angle of the clavus to the apex of the costal areole, and a still broader one at apex, omitting, however, the apical row of small areoles and usually a number of the subapical. These bands may vary in width so as to connect with the form described by Melichar where they are broken into spots and at times become nearly or quite obsolete.

San Francisco, June, 1916, Redwood Canyon, July 2, 1916, August 6, 1916; Dublin Canyon, May 6, 1917. Melichar has described one species in this genus (Jurida), and Kirkaldy two (barbare and arte- misi@), but I am unable to find any characters by which to distinguish them. Mr. Giffard has very kindly brought me a female specimen of barbare, labeled as such in Kirkaldy’s own handwriting, and there is only the paler brown color to distinguish it. Kirkaldy says “front wider’, but the wider front is characteristic of the female manca; he states that the base of the front is truncated but that character depends upon the development of the individual and it is not truncate in Kirkaldy’s specimen before me; the longer pronctum is also a character of the female sex in this genus. The only useful characters left for barbare are its paler color and larger size and I am not sure but both may depend upon maturity. Both forms are found together upon the same bush throughout California as is also a blackish form with pale elytra which seems to be conspecific. This is one of our most abundant insects, being found everywhere upon sage- brush. I have retained the four names in my catalogue until someone has the time to make a careful microscopical study of the male genitalia and other characters. 341. Pissonotus delicatus melanurus, new variety Like the typical form in every respect except that the fulv- ous portions are deepened to piceous in the female or black in the male. The genital characters are obscure but do not seem to differ in any respect from those of the species. ‘This is a pretty form of a piceous or deep black color with the head, pronotum and broad apical margin of the elytra white; the base of the tergum beneath the white margin of the elytra 312 CALIFORNIA ACADEMY OF SCIENCES (Proc. 4tH Ser. is pale or fulvous. Mr. Giffard took a long series in San Joaquin Co., near Tracy, the last of May, 1917, on Grindelia camporum. About one-fourth of those taken were males. Some of the females are as deeply colored as are the males, but some are nearly as pale as some examples of delicatus from Florida now in my collection. The darker males have the femora mostly black and a black line on the base of the tibiz above, the basal segment of the antenne is black and the front is infuscated below. Holotype (No. 378), male, from San Joaquin Co., in col- lection of the California Academy of Sciences. Allotype, female, from San Joaquin Co., in collection of Mr. Giffard. Paratypes in both collections and in that of the author. 342. Pissonotus frontalis Crawf. Mr. Giffard has taken a long series of this species, always on wormwood, Artemisia heterophylla. Among this material the following localities are represented: Santa Cruz Co., June 7, 1917; Niles Can- yon, May, 1916 and 1917, June. 13, 1917; near Stockton, San Joaquin Co., May 30, 1917. Three of the males and three of the females were macropterous. These are piceous- black with the pronotal carinz a little whitish anteriorly, the vertex cinerous with the two black punctures distinct and the front mostly black, the base between the eyes being brownish with the white marks nearly obliterated. The elytra are hya- line as is usual in macropterous individuals in this genus with the nervures pale brown and the basal margin of the clavus infuscated. I took what seems to be the same species at Alpine, Fosters, Lakeside and San Diego, all in San Diego Co., during April and May, 1913. 343. Laccocera vittipennis Van D. Tallac, 6000 feet, Au- gust 22, 1916, brachypterous. The male genital characters in this species are subject to considerable variation in both eastern and western material. The ventral process may be very short or considerably produced and the stiles may be nearly terete and broadly divergent or broader and _ sulcate below and much less divergent. These differences occur in material taken at the same place and time and evidently rep- resent individual variation. Vor. VII] GIFFARD—CALIFORNIA HEMIPTERA SB3 344. Stobaera giffardi, new species Smaller than tricarinata, most nearly related to bilobata and like that species with a dark elytral stigma; face variegated; legs lineated and banded; elytra maculated, the nervures strongly punctate and bearing stiff bristles. Brachypterous form, length, male 2%4 mm., female 31%4 mm. Vertex elongated as in bilobata but broader than in that species, the three frontal carine very prominent at apex of head. Front parallel or nearly so. Second segment of antennz about twice the length of the first; scarcely narrowed at apex. Pronotum as long as the superior aspect of the head, the lateral carine strongly angled behind the eyes, then parallel to the hind margin; lateral carine of the mesonotum straight and more oblique than in bilobata. Elytra scarcely exceeding the abdomen; outer branch of the first sector forked a very little anterior to the forking of the second sector; all the nervures strong and prominently punctate, the bristles long and stiff. ‘Calcar rather narrow and lanceolate. Color testaceous-grey or faintly tinged with brown in the female, darker or almost castaneous in the male. Carine of the head, pronotum and mesonotum pale, maculated with darker in the male, scarcely so in the female. Face brown, paler in the female, in both sexes darker across the apical half of the front; a narrow whitish band crosses the face at the lower angle of the eye and a more slender one on the apex of the front, the darker apical portion of the front with a pale crescent; lateral carinz with two white points between the eyes and on the median is another placed between the lateral; apex of the clypeus marked with two brown points. Antenne brown in the male, mostly pale in the female; sides of the pronotum with a few pale points. Elytra cinerous with faint indica- tions of the dark markings found in tricarinata; stigma small, squarish, nearly black, followed by a transverse white vein. Tergum infuscated on either side toward the base. Legs pale; coxe, femora and tibiz twice banded with fuscous, the femora lineated with pale brown. Metapleura marked with a large round fuscous spot; the ventral segments dotted with fuscous points on either side. Apex of the male genital segment infuscated much obscuring the genital characters; plates vertical, broad and appressed, their apex ob- liquely truncated with the outer angle acute and almost spinose; the stiles covered by the plates. Described from numerous individuals of both sexes taken by Mr. Giffard as follows: Portola Valley, San Mateo Co., May 4, 1917; Santa Cruz Co., June 7, 1917; Niles Canyon, May, 1916, May 23, 1917; Yosemite, June, 1916. These were all taken on wormwood. This species corresponds in size with bilobata and minuta. It agrees with bilobata in possessing a dark stigma and with tricarinata and minuta in the banded legs. In some darkly colored males the elytra are almost entirely fuscous as far as the stigma with the costa pale and always the commissural nervure is pale, interrupted with fuscous beyond the scutellum and again at apex. The young are brown varied with whit- ish with the head short, transverse and black above and the antennz and base of the front are also black; in the later 314 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. moults the insect becomes more variegated and cinerous with the vertex longer.

Mr. Giffard took a long series of this species at Seattle, Wash., July 7, 1917, that differ in no respect from the types in my collection but show much variation in color. My material is from Jamaica and Crawford reports it from Nicaragua, but it has not been reported from intermediate points. It lives on marsh grass along the shore of Puget Sound. 346.

Liburnia muiri, new species Aspect of kilmani but more closely related to lateralis; yellowish-tes- taceous; sides of the tergum partly black; vertex, pronotum and scutellum with a dorsal white vitta; front broad as in detecta, the pale carine inter- ruptedly margined with fuscous. Length to tip of abdomen 3% mm. Vertex oblong, a little longer than broad, gently rounded before, pas- sage to the front rounded, the carine distinct but not sharp over the apex; basal areoles confused, the apical distinct but not attaining the tip of the head as seen from above. Front about as broad as in detecta but very differently shaped, but little narrowed between the eyes; the sides straight and parallel or slightly approaching above. Pronotum as long as the vertex in the macropterous form, a little shorter in the brachypterous; lateral carine broadly divergent, their abbreviated apex curved outward but not obviously continued around behind the eyes. Mesonotum distinctly carinate. Macropterous elytra reaching for one-half their length beyond the abdomen, the brachypterous elliptical at apex and attaining the middle of the fifth tergal segment. Apex of the male pygofer small and nearly round; dorsal notch broad and shallow, the ventral margin entire, regularly arcuated. Stiles broad, blunt but hardly truncated at apex, divergent, lying parallel with the lateral wall of the pygofer, their inner margins fringed with short stiff hairs; anal tube thickened below but without ventral process. Ovipositor of the female much shorter than the pygofers. Color dull yellowish-testaceous. Dorsal line white, generally broadened on the thorax and more slender on the tergum where it may become obsolete; front tinged with fulvous, the carine white, interruptedly bor- dered with fuscous; clypeus black with thick white carine; disk of the metapleura, some marks on the pro- and mesopleure, sides of the venter and tergum black, the latter sometimes quite broadly black. Elytra faintly fuliginous with concolorous nervures, the marginal white, the apical por- ee EO Ee Vor. VIT] GIFFARD—CALIFORNIA HEMIPTERA 315 tion of the others a little infuscated in the macropterous form. In the male the abdomen is black excepting a median vitta above and below and the base of the tergum which is dull fulvous. Genital segment of the male with the margins of the pygofer above and the anal tube pale. Legs concolorous or obscurely lineated, the tips of the spines and the tarsal claws black. Described from one male and four female examples taken by Mr. Giffard at Portland, Oreg., on grasses, July 3, 1917. One of the females is macropterous. This species has the color, stout form and pale dorsal vitta of kilmani, but the front and vertex are a little broader and the characters of the male genitalia are entirely different. It gives me pleas- ure to name this species for Mr. Frederick Muir of Honolulu, who is giving this subfamily a much-needed and careful revision.

Librunia semicinctus, new species Closely allied to muiri but with very different male genitalia; pale yellowish-testaceous with a blackish cloud on either side of the tergum and some blackish marks beneath, more extended in the male; frontal carine pale or concolorous, the frontal fovze becoming darker apically next the carine. Length 2-3% mm. to tip of the abdomen. Vertex broad, nearly square, shorter than in muiri, the anterior margin but feebly arcuated; median carina obtuse but moderately distinct over the apex of the head. Front nearly as in muiri, the sides very slightly arcu- ated in the female. Antenne as in the preceding, the first segment scarcely longer than wide; the second attaining the base of the clypeus. Pronotum as long as the vertex, the carinz rather obscure, the lateral obviously curved around behind the eyes. Brachypterous elytra reaching on to the fifth tergal segment, the macropterous exceeding the abdomen by one-third their length. Genital segment of the male very short; aperture transverse, very wide below, the ventral wall nearly straight across; dorsal sinus broad, reaching to the preceding segment; ventral nearly as deep as broad, its fundus rounded. Stiles narrow and long, broadly divergent, nearly parallel to the lower margin of the pygofer, a little curved and acute at apex; ventral wall of the anal tube with a slender median prolongation which is ex- panded interiorly as a broad plate and abruptly incurved beyond, its apex nearly attaining the base of the stiles. Oviduct of the female short, black, not nearly reaching the apex of the pygofers. Color dull yellowish-testaceous. Frontal fove with a black vitta be- yond the middle next the lateral carinee; this vitta may be interrupted above and may be widened below next the apex. Lateral fove of the clypeus usually black. Sides of the tergum with a more or less extended blackish area; the pleural pieces and venter more or less maculated with 316 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4rH Ser. fuscous or black; the metapleura sometimes with a black spot. Legs, antennze and rostrum pale, the femora sometimes faintly lineated, the rostrum tipped with black. Apex of the tarsi black. Described from four male and nine female brachypterous examples taken by Mr. Giffard at Portland, Oreg., July 3, 1917, and Seattle, Wash., July 7, 1917. One macropterous female taken at Portland is darker with the abdomen, pectus and fovee of the face mostly black and the elytra quite deeply fuliginous. This species is very close to kilmani, but the vertex is shorter with its carine less acute, the front is dif- ferently marked and the whole insect is paler in color. The male genitalia are very similar in the two species, but in senmucinctus the aperture of the pygofers is more transverse, the plates are not as straight across, are broader and less acute at apex and are without the fring of hairs found in kilmanit and the anal process is more incurved at apex and differently shaped. The female may be distinguished from muirt by the shorter vertex, the more curved lateral pronotal carine, the different markings in the frontal fovz and the want of a regular fuscous line exterior to the lateral carinz of the front. Holotype (No. 381), male, from Portland, in collection of the California Academy of Sciences. Allotype, female, from Portland, in collection of Mr. Gif- fard. Paratypes in both collections and in that of the author. 350. Liburnia consimilis Van D. San Francisco, May, 1916; Portola Valley, San Mateo Co., May 4, 1917; near Stockton, May 31, 1917; Blue Lakes, Lake Co., August 3, 1916; Yosemite, June 16, 1916; Tallac, August 22, 1916: Soda Springs, Placer Co., August 24, 1916. This is the most abundant and widely distributed delphacid in Califor- nia. The males are ordinarily black with the pronotum more or less invaded with white posteriorly. Some females are almost as deeply colored as are the males, but generally they are much paler and even become fulvous with the basal angles of the pronotum black, when they much resemble campestris, but they can always be distinguished from that species by the narrower and longer vertex with more distinct carinz —— Vor.

Niles Canyon, September 3, 1916, one macropterous male; Monterey Co., June 11, 1917, six macropterous and nine brachypterous examples. 354. Liburnia fluvialis, new species A large stout brown species closely resembling magnifrons; abdomen and pleural pieces marked with black. Length 3% mm. Head short, broad, nearly as wide as the pronotum, broadly rounded before in both diameters, apex smooth with the carinz obsolete there. Vertex one-half broader than long, the fove obscure. Front broad, a little narrowed from ocelli to apex; carine distinct below. Pronotum nearly as long as the head viewed from above, almost truncate between the eyes, feebly excavated behind; carinz obtuse, indistinct. Mesonotum a little longer than the pronotum, carine normal but obtuse and indistinct. Elytra almost attaining the apex of the second tergal segment, small, truncated, the nervures distinct, concolorous. Abdomen broad, ovate, with the median keel distinct. Hind tibia scarcely longer than its femora, the calcar about one-half the length of the first tarsal segment, smooth, broad at base, the sides straight, wanting the teeth usually found there. Color dull testaceous-brown, almost uniform. Front with a row of obscure darker blotches next the carinz, sometimes wanting. Median line of the tergum pale with a fuscous point on either side at each segment, the posterior pair usually extended in a line; sides of the tergum broadly black more or less interrupted by an irregular pale mark on each segment, the submargins of the segments with a black line either side the disk; edge of the connexivum pale. Beneath pale, the sides of the venter marked with fuscous. Legs pale, faintly lined with brown. Antenne pale, cheeks with a brown spot at base of the antenne. Anal tube black. Elytra nearly hyaline with whitish nervures, the marginal heavy. Pro- and metapleura with a row of fuscous spots. Male similar but with the dark markings more pronounced. Male genitalia much as in consimilis. Aperture of the pygofers broad below but with the sides well rounded; ventral notch broad, moderately deep, with its fundus rounded. Stiles broadly divergent, short and straight. Apex of the anal tube forming a small lobe on either side below the middle but scarcely produced ventrally. Described from two males and five females taken by Mr. Giffard near Stockton, May 30, 1917. This species is appar- ently quite near magnifrons, but is very distinct in the male genital characters. 318 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4rH Ser. Holotype (No. 382), macropterous male in collection of the California Academy of Sciences. Allotype, brachypterous female, in collection of Mr. Gif- fard. Paratypes in both collections and in that of the author. 355. Liburnia occlusa Van D. Mr. Giffard took a long series of this species on Juncus Iesurii at the following local- ities: San Francisco, July 13, 1917; Santa Cruz Co., June oP 1917), Monterey,'Co.s; June 1Ol7 mean Stcktony May, 30, 1917. Macropterous examples were taken only in the San Joaquin Valley, but both there and in Santa Cruz Co. two forms of brachypterous females were found. The dark form described by me in 1897 and a pale form of an almost uniform testaceous-yellow color. In a long series an almost complete gradation is found connecting these two forms and this will possibly be found to be the case in the eastern linea- tipes as well. th Pages 155-160.

Ni us 20 During the year 1917 there has been an accession of 28 new members, and the Academy lost by death 10, by resignation 13, and by being dropped for arrearages in dues 28. Early in the year came the last call to Mr. Theodore H. Hittell, whose long and earnest work for the Academy, and whose devotion to its interests, have been and are keenly ap- preciated by all who have been in close touch with Academy affairs. Later in the year Mr. Lyman Belding, well known for his work in ornithology, passed away and also Mr. Edward Bosqui—old and valued members—whose going depletes the ranks of the older generation and reminds us of the increasing responsibility that falls upon the younger generation and more recent members to carry forward, in a manner worthy of the established tradition, the work that has been so well begun by those who brought the Academy into being and shaped its early course. The full list of those called by death is as follows: June 15,1918 320 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Altmann.

THE STEINHART AQUARIUM The most notable event in relation to the Academy in the past year, was the gift to the Academy by the late Ignatz Steinhart of $250,000 for an Aquarium building. Mr. Stein- hart had, for several years, cherished the desire to provide a public aquarium for the people of San Francisco, 324 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. During the last fifteen or twenty years various efforts had been made looking toward the establishment of a public aquarium in San Francisco. One of the first to give the matter serious consideration was Loyd Tevis, a public-spirited citizen of San Francisco. After giving much time and thought to the question and expending a considerable sum in making a study of the aquariums of the world, unforeseen difficulties developed which made it impracticable to carry out the purpose, much to Mr. Tevis’s regret. The next to take up the matter was Sigmund Steinhart, an- other philanthropic citizen of San Francisco. At his death in 1910 he left a certain sum of money with his brother, Ignatz Steinhart, with the request that it be used for aquarium pur- poses, if he found it feasible to do so. Mr. Ignatz Steinhart took up the matter at once and became deeply interested in it. His wish and hope was to provide the city of San Francisco and the people of the entire Pacific Coast with a modern, up-to- date public aquarium. Numerous and diverse difficulties and discouragements arose, however, and Mr. Steinhart had almost abandoned the hope of ever being able to realize the dream of his brother and himself. Early in 1916 Dr. Evermann, Director of the Museum, had a number of conferences with Mr. Steinhart, with the result that Mr. Steinhart’s interest revived. Finally he an- nounced, at an aquarium luncheon at the Palace Hotel, Sep- tember 21, 1916, that he would undertake to provide a build- ing adequate in every way for an aquarium equal to any now existing if the city of San Francisco would make adequate provision for its maintenance. He also announced that he desired that the aquarium be located in Golden Gate Park and that its control and management be placed with the California Academy of Sciences. Following this, a charter amendment was drawn and sub- mitted to the electorate of the city and county of San Francisco at the election in November, 1916, which directs the super- visors to include in their annual budget an item of not less than $20,000 for the maintenance of a public aquarium. This amendment carried by an overwhelming majority and Mr. Steinhart at once began considering plans and specifications. It was his earnest desire and hope to have the building com- pleted and the aquarium in operation in his life time, but, to the Vou. VII] GRUNSKY—PRESIDENT’S REPORT FOR 1917 325 great regret of all, this was not to be. On April 27, 1917, he became ill, and died on May 15. When the will was made pub- lic it was found that Mr. Steinhart had made ample provision for a public aquarium, by bequeathing “to the California Academy of Sciences the sum of two hundred and fifty thou- sand dollars ($250,000) for the erection and completion of an aquarium to be located in the Golden Gate Park of the city of San Francisco, and adjacent to or adjoining the new buildings and museum of said Academy of Sciences in said park, and subject to the following conditions: 1. Said aquarium to be called the Steinhart Aquarium, and a bronze bust of my brother Sigmund Steinhart, now deceased, but joint donor with me, to be erected and dis- played in some convenient place in said Aquarium build- ing. 2. The location, plans, and specifications, and also the appurtenances and installations therein, to be submitted to my executors and to be approved by same. 3. The final cost of said Aquarium not to exceed to my estate the sum of said $250,000, to be certified to by the principal officials of said Academy of Sciences and the architect selected for the construction of said Aquarium. 4. The management, superintendence, and operation of said Aquarium to be in charge and under the direction of said Academy of Sciences; and I expect that the necessary funds for the maintenance and operation of said Aquarium will be furnished by the city of San Francisco for the benefit of the inhabitants thereof, or those who may enjoy said Aquarium and derive knowledge and information therefrom.” The Academy of Sciences, the executors, and the proper city officials of San Francisco are all deeply interested in seeing the Aquarium in full operation at an early date and are all working in perfect harmony toward the realization of that end. The amount of money to be put into the building will pro- vide an Aquarium building superior to any now in existence. The Aquarium will be for both fresh and salt water species, and there will be out-door pools for fur seals, sea lions, elephant seals, porpoises, and other aquatic mammals and reptiles. 326 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Ser. The city of San Francisco is fortunate in having had as one of its distinguished citizens a man of vision as Ignatz Steinhart was; aman who had prospered in this world, and who, having prospered, wished to do something worth while for the city that had for so many years been his home. Men and women of wealth are coming more and more to realize that one of the very best and most satisfactory ways to dispose of wealth is to give it to scientific and educational institutions to aid in the increase of knowledge and its diffusion among men. Mr. Steinhart was such a man, and the name of Ignatz Steinhart will ever be held in grateful remembrance by the multitudes who will visit the Steinhart Aquarium every year and be enter- tained and instructed by the various forms of aquatic life it will contain. THE WILLIAM M. FITZHUGH COLLECTION OF INDIAN BASKETRY AND POTTERY This collection of Indian baskets, pottery, and stone imple- ments was assembled by the late Professor and Mrs. T. S. G. Lowe and represents many years of diligent collecting and sus- tained interest on their part. When the collection came into the possession of Mr. Fitzhugh in 1914 he very kindly offered to install it in the new museum building of the California Academy of Sciences, then under construction. The offer was accepted and, upon the completion of the building, the installa- tion was made. The hall, 170 feet long by 15 feet wide, at the south of the Mammal Hall and facing on the open court, has been devoted entirely to this exhibit. The collection is so large, consisting of more than 15,000 different objects, as to preclude the possi- bility of installing it in its entirety; but by eliminating dupli- cates and the articles of least ethnologic or educational interest, space was found for practically all the really important speci- mens. The installation of the collection was done under the immediate direction of the late William Altmann, and was made primarily with reference to artistic effect. Mr. Altmann’s keen artistic sense together with his knowledge of Indian basketry and wide experience in arranging collections of this kind enabled him to do this work most satisfactorily and the hall now makes a very attractive appearance. A tribal or cere- Vor. VII] GRUNSKY—PRESIDENT’S REPORT FOR 1917 327 monial classification would have considerable educational ad- vantage and would probably not detract materially from the artistic effect. The Basket Hall has proved a great attraction to specialists and to the general public. When the number of visitors at the Museum is large, the Basket Hall is usually crowded, and at all times it attracts its share of interest. Many visitors are observed to tarry long, studying the objects critically. Teachers in the public schools frequently bring their classes to the Museum and make use of these exhibits in their school work. Some idea can be gotten of the character of these exhibits trom the photographs reproduced in this report. NOTABLE ACCESSIONS TO THE MUSEUM AND LIBRARY The accessions to the Museum and to the Library during the year have been many and valuable. Only a few of the more notable ones will be mentioned here. In the Department of Botany large and valuable collections of herbarium specimens have been received as donations from Doctors Charlotte and Fred Baker of San Diego, Mrs. A. L. Coombes of San Francisco, Miss Sophie Fauntleroy of Santa Barbara, Mrs. Elizabeth Parsons Hawver of San Francisco, Dr. Harold Heath of Stanford University, Mrs. G. Earle Kelly of Alameda, Mrs. Ernest Meiere of San Francisco, Mr. Justin P. Moore, Mrs. Zelia Nuttall, Mr. G. P. Rixford of San Fran- cisco, Mr. L. E. Smith of Sisson, Cal., Dr. E. C. Van Dyke of Berkeley, Miss Ethel Wickes of San Francisco, and Mrs. Elizabeth Wright of Calistoga. In addition to these there have been received either by ex- change, purchase, or exploration, many large and important collections. The Department of Entomology has received a number of unusually large and important donations, chiefly from Dr. F. E. Blaisdell of San Francisco, Mr. B. Preston Clark of Boston, Dr. Frank C. Clark of Los Angeles, Dr. W. M. Crowfoot of Suffolk, England, Mr. Frank Daggett of Los Angeles, Mr. C. A. Hill of Los Angelés, Mr. W. M. Giffard of Honolulu, Mr. J. August Kusche of Eldridge, Cal., Mr. E. J. Newcomer 328 CALIFORNIA ACADEMY OF SCIENCES [Proc. 47H Ser. of Palo Alto, and Mr. F. X. Williams of Honolulu. These collections total many thousand specimens. The Department of Ornithology also has received a number of important gifts of specimens of birds and birds’ eggs, the most valuable being a collection of 748 birds’ eggs from Mrs. C. A. Treuholtz of Oakland, another of 215 eggs from Mr. Wm. H. Evermann of Burlington, Indiana, another of 103 eggs and 36 bird skins from Messrs. J. & J. W. Mailliard of San Francisco. And, through the kindly interest of Mr.-L. J. Phelps, U. S. Customs Examiner, San Francisco, the Academy has received 25 packages of egrettes, bird skins, and feathers seized by the Customs office. The Department of Mammalogy has received a number of notable gifts, the most important being: Five specimens of the Stone or Black Sheep (Ovis stone). These were presented to the Academy by Mr. H. O. Harrison of San Francisco who obtained them in British Columbia. They are excellent ma- terial for a fine habitat group. The Academy is also indebted to the U. S. Bureau of Fisheries for 14 fur seals from the Pribilof Islands. Although these are seals found dead on the rookeries they are nevertheless suitable material for a habitat group. Through the courtesy of Mr. C. J. Albrecht of the Museum of the University of Washington the Academy has received five excellent specimens of the Roosevelt elk. And Mr. Leslie Simson of Oakland has generously donated to the Academy the following skins and skulls of Alaska mammals: three caribou, 3 Dall’s sheep, 2 mountain goats and 1 moose. The most notable donations to the library have been the fol- lowing: From Mr. L. E. Smith of Sisson, Cal., 164 books and pamphlets ; from the U. S. Department of Agriculture, through Dr. Walter H. Evans of the Office of Experiment Stations, 266 volumes and reports of that office; from Mr. F. X. Williams of Honolulu, 649 scientific books, pamphlets and periodicals. To all of these donors who have so generously contributed to the Museum’s collections and library grateful acknowledgment is made. Vor. VIT] GRUNSKY—PRESIDENT’S REPORT FOR 1917 329 HONORARY MEMBERS AND FELLOWS Under authority of the Constitution the Academy at the last annual meeting (February 21, 1917) elected to Honorary membership three of the most distinguished scientific men in America, namely: Dr. John A. Brashear of Pittsburgh, Pa., Dr. Robert S. Woodward, President of the Carnegie Institu- tion of Washington, and Dr. Frederic A. Lucas, Director of the American Museum of Natural History. Section 4 of Article II of the Constitution provides for a class of members to be known as Fellows. Any person trained in the methods of science and engaged in scientific work who has been a Member of the Academy one year or more may, upon recommendation of the Council, be eligible for election by letter-ballot as a Fellow of the Academy. Early in the year the Academy availed itself of this privilege and the following distinguished members were elected Fellows: Dr. John C. Branner, President Emeritus of Stanford Uni- versity. Dr. W. W. Campbell, Director of the Lick Observatory. Dr. David Starr Jordan, Chancellor Emeritus of Stanford University. Dr. Wm. E. Ritter, Director of the Scripps Institution for Biological Research. I am sure I voice the feeling of all when I say that the Academy is proud to begin its roster of Fellows with the names of these distinguished men of science. And it is equally proud to number among its Honorary members the three distin- guished men who were elected to that class. Despite the disturbed conditions throughout the world, the Academy has during the past year continued to make progress. While the Academy is far from being in position to do all that should be done in the matter of collecting and housing material of scientific interest from land and sea, for study and display, it has nevertheless done what it could with the means at its command and makes grateful acknowledgement of the fact that its work has been facilitated and the interest of the public stimulated by many donations, among the most notable of which are a contribution of $3500.00 by Mr. Herbert Fleishhacker credited to his mother, Mrs. Delia Fleishhacker, 330 CALIFORNIA ACADEMY OF SCIENCES __ [Proc. 47H Ser. which was devoted to the installation of the San Joaquin Valley Water-Fowl group, recently opened to the view of the public, and the contribution of $3,000, which will be increased to $3,500, by Mr. A. K. Macomber, which is being used in the installation of a White Pelican group. More specific refer- ence to these and other donations which the Academy has re- ceived during the year will be found in the report of the Direc- tor of the Museum. The activities of the Academy along scientific lines will ap- pear from the reports of the Director of the Museum and of the curators of the several departments into which the Acad- emy’s work is divided. These reports show that there has been no lack of earnest co-operation and there has been always an earnest endeavor to do all that could be done with the means and within the time available. I again acknowledge with pleasure the valuable service that is being rendered by those who with the facilities provided by the Academy are engaged in contributing to the fund of human knowledge and wish to thank them for their devotion to the work. May they and the Academy continue to merit and ob- tain the approbation of the public and let us hope for a growing material support. The Academy will soon have outgrown the facilities which have been provided in the first unit of its building, but it has no means at present in sight with which to make extensions. It is carrying as large a debt as seems wise—some $319,000.00. Its annual interest obligation amounts to about $16,300.00. There is some satisfaction, however, in being able to note that the indebtedness has been reduced during the year by $10,000, as will appear more fully in the financial statement of the Treasurer. I speak for your officers when I say that the cordial support that has come to them from the membership and from the public in their endeavor to fulfil their responsibilities is thor- oughly appreciated. XIII REPORT OF THE DIRECTOR OF THE MUSEUM FOR THE YEAR 1917 BY Barton WARREN EVERMANN Director of the Museum The annual report of the Director for the year 1916 was presented to the Academy at the annual meeting of February 21, 1917. At that time 11 of the large habitat groups, four intermediate groups and two small groups had been completed. Since then new groups have been completed as follows: California Condor.—Although the background for this group had been painted in 1916 by Mr. Charles Abel Corwin, it was not until in 1917 that the necessary birds for the group were obtained. In May of that year three splendid birds, an adult male, an adult female, and a young bird perhaps one year old, were secured, in Ventura County by Mr. Jos. P. Herring. These have now been installed and make a very striking group. San Joaquin Valley Water-Fowl.—This group shows the various species of ducks, geese, and other water-fowl that spend the winter in the San Joaquin Valley. Six species of geese and about 25 species of ducks are represented. The birds were obtained by Messrs. Paul J. Fair and Arthur L. Reed, with the assistance of Mr. Thos. Rooney, in the vicinity of Gadwall, Merced County, California, through the courtesy of the Los Banos Gun Club. The background was painted by Captain Charles Bradford Hudson and makes a scene of unusual interest and beauty. On the whole, this group is generally regarded as the most beauti- ful that has as yet been completed. The Academy has been able to install this really remarkable group through the liberality of Mr. Herbert Fleishhacker who very generously met all the expenses connected with its prepara- tion. California Clapper Rail—This is one of the most attractive of the small panel groups thus far prepared. There are shown 332 CALIFORNIA ACADEMY OF SCIENCES __ [Proc. 4TH Serr. the nest, eggs and a pair of the birds, as found in the salt- marshes on Bay Farm Island south of Alameda. The group was prepared by Paul J. Fair assisted by Miss Olive E. Cutter. The background was painted by Miss Cutter. California Linnet or House Finch.—This small panel group, originally installed by Mr. Rowley, has been rearranged by Mr. Fair and thereby very greatly improved. It now makes a very attractive and instructive exhibit. Coast Bush-Tit——This is by many regarded as the most ar- tistic and beautiful of the small groups that have been com- pleted. It shows a pair of Bush-Tits and their curious pensile nest in a eucalyptus tree near the Museum in Golden Gate Park. Other eucalyptus trees show through the fog in the back- ground, which was painted by Miss Olive E. Cutter. Group prepared by Mr. Fair. California Ground Squirrel—This small panel group, pre- pared by Mr. Jos. P. Herring, shows a family of this noxious rodent in their natural environment near San Francisco. Santa Crug Chipmunk.—This is another of the small Cali- fornia mammal groups of which we hope to have at least 20 in the mammal hall. The animals shown belong to the subspecies, Eutamias merriami pricei, common throughout San Mateo, Santa Cruz and Monterey counties. The group was prepared by Mr. Joseph P. Herring. In addition to the above, already completed, several other groups, large or small, are in progress. These include groups of the White Pelican (nearly completed), the Roosevelt Elk, the Fur Seal, the Elephant Seal, Sharp-shinned Hawk, Nuttall Sparrow, Red-tail Hawk and Yellow-billed Magpie. When these shall have been finished there will remain space only for a number of small mammal groups and possibly, for a few groups of intermediate size. In addition to the habitat groups we have placed in the bird hall three floor cases in which are shown many of the common birds found in Golden Gate Park. It is planned to install a case in which will be shown, by seasons, all of the more common birds of the Park and vicinity. Sulphur-bottom Whale (Balenoptera sulfurus).—Within the year Mr. Herring completed in a very satisfactory manner the installation of the skeleton of a Sulphur-bottom Whale Vou. VII] EVERMANN—DIRECTOR’S REPORT FOR 1917 435 which was acquired in 1915. This has proved to be one of the most interesting exhibits. It is placed in a suitable open shed in the court between the bird hall and the research wing. The whale from which this skeleton was obtained was taken in 1908 off the west coast of Vancouver Island by the whaler “St. Lawrence,’ operating from the Pacific Whaling Company's station at Kyuquot, B. C. It was a bull whale. Total length, 75 feet’. Its weight was estimated at 80 tons. It is estimated to have produced 60 barrels of oil, about 8 tons of fertilizer, and 400 pounds of baleen or whalebone. Other measurements are as follows: Length of lower jawbone, 19 feet; of upper jaw, 15 feet 4 inches; head, 20 feet 6 inches; longest rib, 10 feet 4 inches; fore flipper, 10 feet 10 inches; skull, 5 feet; width at eleventh iby bl-feet; depth, 13 feet: The Sulphur-bottom is the largest of all the whales. It is said to reach a length of 60 to 100 feet. Captain Scammon records one which was 95 feet long; girth 39 feet; length of jawbone 21 feet ; length of longest baleen 4 feet ; yield of baleen 800 pounds; yield of oil 110 barrels; estimated weight of whole animal 147 tons. The Sulphur-bottom Whale occurs at all seasons on the Cali- fornia coast. During the period from May to September they formerly might be seen in large numbers close in shore, at times playing about ships at anchor in the open roadsteads, or near islands or capes, but as a rule they do not approach vessels with the same boldness that the Finback does. This species is con- sidered the swiftest whale afloat, and for this reason it is but seldom pursued and still more rarely taken. Quite contrary to the more or less widespread popular belief, whales are not fish, but mammals. They are warm blooded ani- mals, bring forth their young alive and suckle their young, like _ the horse and the cow. A whale simply resembles a fish ex- ternally because it is adapted to life in the water; but it is no more a fish on that account than a bat is a bird because it is adapted to flying. Whales are the most perfectly aquatic of all mammals; they never leave the water, although legends have represented them as pasturing upon the shore, and Aelian spoke of them as com- ing out on the sand and basking in the sun’s rays. 1Jt is claimed that the total length in the flesh was 86 feet. 334 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH Sep. Whales possess no. externally-visible hind-limbs; vestiges, however, are present under the skin. The fore-limbs are in the form of paddles which appear to be used as balancers rather than in locomotion. The tail is fish-like in form, but the flukes are horizontal instead of vertical as in fishes, which arrange- ment enables the whale to rise promptly to the surface when it needs to breathe. When the whale breathes the expired air rushes out through the nostrils, or blow-hole, the water vapor in the breath condenses and appears like a column of water. The Sulphur-bottom Whale skeleton has been housed in a suitable open shed erected in the court between the research wing and the bird hall. This shed is 94.5 feet long by 24 feet wide, 22 feet high at the comb and 14 feet at the eaves. The shed is open on all sides. The roof is supported by 14 posts or columns each 12” x 12” x 13’ 9”, all set in a concrete base which is continuous on all sides. Between the posts is a double heavy iron rail. The construction is architecturally substantial and pleasing in appearance. The total cost of the shed has been $1777.08. EMPLOYEES A few changes in the personnel of the Museum have occurred within the year. On January 31, the resignations of Mr. John Rowley and Mr. A. L. Bolton were received and accepted. Mr. Rowley had for several years been chief taxidermist and chief of exhibits. Mr. Bolton had been an assistant to Mr. Rowley for some years. Mrs. M. L. Pariser assistant department of exhibits, resigned May 14, and Miss Olive E. Cutter was ap- pointed to the vacancy May 21. Mrs. Mary C. Kaeding was appointed check-room attendant May 1, and served until Octo- ber 31. Mr. Jos. P. Herring, assistant department of exhibits, resigned June 30, and Mr. Ignatius W. McGuire, who had for several years rendered very efficient and valuable service as general office assistant, resigned December 24, to enter the University of California. Th employees of the Museum during the year have been as follows: Dr. Barton Warren Evermann, Director and Executive Curator of the Museum and Editor; W. W. Sargeant, Secre- tary to the Board of Trustees; Miss Susie Peers, stenographer VoL. VII) EVERMANN—-DIRECTOR’S REPORT FOR 1917 335 and typewriter; Joseph W.

Yale, night watchman; Mrs. Johanna E. Wilkens, janitress; Mrs. Mary C. Kaeding, check-room attend- ant; Patrick J. O’Brien, day watch; William J. Owen, tem- porary night watchman. ACCESSIONS TO THE MUSEUM The Accessions to the Museum during the year have been many, as shown by the reports of the respective curators and in the detailed list in the appendix to this report. A few of the more notable accessions are mentioned in the President’s report (pp. 327 and 328). | TAXIDERMISTS LABORATORIES In the budget for 1916 an item of $1500 was provided for a taxidermists’ shop or laboratory. Finding that this amount would not provide a building that would present a satisfactory appearance in any location ad- jacent to the Museum, it was decided to erect two structures on the roof, one on the Research Wing at the north end, the other in the corresponding position on the roof of the Bird Hall. This was done. The former is 30’ x 15’ and 10 feet high, the latter is 27’ x 12’ and 10 feet high and is divided by a par- tition into two rooms. ‘These structures have been erected in 336 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. such a way as to meet the building and insurance requirements. They are not observable from the ground. They have cost only $529.04 and meet present needs fairly well. VISITORS TO THE MUSEUM That the Museum is meeting a real public need in a very effective way is evidenced by the number of visitors. The Museum has been open every day during the past year, from 10 A. M. to 4 P. M. on week days and from 10 A. M. to 5 P. M. on holidays, including Saturdays and Sundays. The number of visitors has varied from fewer than a hun- dred on bad days to more than 9000 on Sundays. The attend- ance by months during the year 1917, has been as follows: AGUA.

Many teachers have brought their classes to view the habitat groups and other exhibits. The practice, begun last year, of having a member of the Museum staff accompany each class or school about the halls and explain briefly the various exhibits, has been continued. When time permits the schools are then taken into the auditorium and are shown mov- Vou. VII) EVERMANN—DIRECTOR’S REPORT FOR 1017 337 ing pictures of the animals shown in some one of the groups. Steps are being taken to bring about a closer co-operation be- tween the Museum and the schools whereby the Museum will be able to render even greater service to the public along educa- tional lines. LECTURES A course of free popular lectures on scientific subjects has been maintained throughout the year, on the third Wednesday evening of each month. These have been given at the regular monthly meetings of the Academy, usually held in the Board room of the Mechanics Institute Library. The list of lecturers and their subjects will be found in the President’s repeort (pp. 320 and 321). The Academy has also continued the Sunday afternoon course of popular lectures which proved so successful last year. ‘These lectures are given in the auditorium of the Mu- seum at 3 P. M. every Sunday. The attendance at the lectures is limited only by the capacity of the hall. One of the urgent needs of the Museum is a much larger hall to accommodate the larger audiences who desire to attend these lectures. As heretofore the success of the Sunday afternoon lecture course is due to the energy and resourcefulness of the lecture committee, Messrs. Roy E. Dickerson, W. W. Sargeant and FE. P. Van Duzee. The list of the lectures given in 1917 will be found in the President’s report (pp. 321-323). There are certain expenses connected with the lectures which, though small, the Academy finds difficulty in meeting from its present income. These expenses include pay of ushers, print- ing of notices, preparation of illustrative material, travel ex- penses of lecturers, operator of stereopticon, and other small expenses. If the Academy could secure a modest endowment the in- come from which to be used in meeting expenses incident to lectures, it would be able to make the courses even more valu- able and popular than they have been in the past. An endow- ment that would yield an annual income of $500 to $1000 would help greatly. 338 CALIFORNIA ACADEMY OF SCIENCES {Proc. 4rH Ser. DEPARTMENT ACTIVITIES The curators and their assistants have been able to devote most of their time to the enlargement, care and study of the collections under their charge. The condition and activities of the different departments are fully shown in the reports of the respective curators and need be referred to here only briefly. Department of Botany.—The usual activity in this depart- ment has continued. The Curator, Miss Eastwood, has been indefatigable in adding to, mounting, labeling, and caring for the collections in her charge. The herbarium now numbers more than 45,000 specimens all mounted, labeled and_ sys- tematically arranged. The educational activities of the de- partment have continued unabated through the weekly meet- ings of the Botanical Club, the flower exhibit and public lec- tures to clubs and schools. Department of Entomology.—Mr. E. P. Van Duzee, Cura- tor of this department, has been very active not only in mount- ing, classifying, and determining the material previously ac- cumulated but he has been remarkably successful in securing donations of large and valuable collections of insects in various groups. He also found time to do considerable field work which added many specimens to the department’s collections. Mr. Van Duzee has been successful not only in securing many important donations to the department but he has been equally successful in bringing the Museum in close touch with the entomologists of the country, with the result that a number of large and valuable collections some of which have lain in the Museum for many years unworked and unstudied, are now be- ing studied and identified by specialists in the various groups. Department of Exhibits—The work of this department has been under the immediate direction of Mr. Paul J. Fair. The work that has been done in the installation of habitat groups and other exhibition material has been of a high order of ex- cellence. Two large habitat groups (the San Joaquin Valley Water-l*owl and the California Condor), and five small groups (California Clapper Rail, Linnet, Bush-Tit, Chipmunk and Ground Squirrel) have been completed. Two others (White Pelican and Sharp-shinned Hawk) are nearly finished, and several others, including the Roosevelt Elk, Fur Seal, Nuttall VoL. VII] EVERMANN—DIRECTOR’S REPORT FOR 1917 339 Sparrow, Red-tail Hawk, Yellow-billed Magpie and Wild Cat, have been commenced. A series of the birds found in Golden Gate Park and vicinity has also been placed in the Bird Hall where they attract much attention. Department of Herpetology—The Curator, Dr. Van Den- burgh, and the Assistant Curator, Mr. Slevin, have been alert in enlarging and caring for the collections of this department. There have been added to the department’s collections dur- ing the year a total of 1635 specimens, of which 1519 were ob- tained during field exploration carried on by the Curator and the Assistant Curator. The collections of the department now number 35,451 specimens. The classification and arrangement of the collections have continued throughout the year and gratifying progress has been made. The Curator has continued his research work during the year, especially on the gopher and garter snakes of the Pacific Coast. Department of Paleontology.—The Curator of this depart- ment, Dr. Dickerson, has made commendable.progress in classi- fying, labeling and arranging in trays and cases the fassils and recent shells under his care. All the marine shells of the Hemp- hill collection have been numbered and placed in proper cases. Much has been done with other groups. Within the year considerable field work has been done by the Curator, chiefly in the vicinity of the Marysville Buttes, in San Diego County, and in the area between Tejon Pass and Cajon Pass in the San Andreas Rift zone, the latter 1n co-operation with Dr. L. F. Noble of the U. S. Geological Survey. Considerable work has also been done toward geological mapping in the Santa Rosa and Petaluma quadrangles. Mr. F. M. Anderson, formerly curator of this department (a posi- tion he relinquished because of the heavy demands upon his time in connection with commercial oil investigations), has given considerable time to a study of the rich paleontological material which he secured for the Academy during his work in northern South America in 1914-1916. Department of Invertebrate Zoology.—Some field work was done for this department in the vicinity of Friday Harbor, Washington, by Mr. and Mrs. T. S. Oldroyd, resulting in a 340 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4rH Ser. considerable collection of marine invertebrates, chiefly mol- lusks. Some collecting was done also in the vicinity of Santa Cruz Island and a little in Monterey Bay. Department of Mammalogy.—In the absence of a curator of this department, no effort was made in the past year to increase its collections. A few specimens, however, have been received from miscellaneous sources, increasing the catalogue entries from 2300 to 2336. The most notable of these were 5 excel- lent specimens of the Stone or Black Sheep (Ovis stonei) of British Columbia, for which the Academy is indebted to Mr. H. O. Harrison of San Francisco; skins and skulls of 3 caribou, 3 Dall sheep, 2 mountain goats, and one moose, all from Alaska, which were generously donated to the Academy by Mr. Leslie Simson of Oakland; 14 fur seals from the Pribilof Islands, fur- nished by the U. S. Bureau of Fisheries; and 5 Roosevelt elk from the Olympic Peninsula, through the kindness of Mr. J. C. Albrecht of the Museum of the University of Washington. Department of Ornithology.—Very little field work was done by this department during the year. A few miscellaneous specimens were collected by various members of the Museum staff and several donations of single specimens or small col- lections were received. The Director gave his personal attention to the care of the collections of birds, birds’ eggs and nests, and mammals. Mr. Joseph Mailliard has made use of the Academy’s collec- tions in connection with his studies of California birds. Library.—Reasonable progress has been made during the year in classifying, cataloguing, and arranging the books on the shelves. A total of 670 linear feet of shelving has been added which permits a material reduction in the quantity of books and pamphlets which were previously boxed or stacked on the floor. The additions to the library during the year were 749 bound volumes besides several hundred pamphlets and excerpts. It is hoped that funds may be available next year to keep one or more library assistants continuously employed. PARTICIPATION IN IMPORTANT SCIENTIFIC MEETINGS The Academy took an active and important part in the second annual meeting of the Pacific Division of the American Asso- VoL. VII] EVERMANN—DIRECTOR’S REPORT FOR 1917 341 ciation for the Advancement of Science, and Affiliated Societies, at Leland Stanford Junior University, April 5 to 7, 1917. The attendance of members of the Academy and the number who presented papers were very gratifying and creditable to the Academy, as evidence of the fact that the Academy is taking an active and important part in the scientific activities of the Pacific Coast. Among the members of the Academy who par- ticipated in the Stanford meeting were the following: Dr. John Caspar Branner, Prof. A. L. Barrows, Dr. Douglas H. Camp- bell, Dr. W. W. Campbell, Dr. Bruce L. Clark, Prof. Geo. A. Clark, Dr. Roy E. Dickerson, Dr. Barton Warren Evermann, Mr. Ce EB. Gtunsky, Dr. Harvey M. Hall, Dr. Charles A. Kofoid, Mr. W. S. W. Kew, Dr. G. C. Gester, Dr. F. B. Sum- ner, Dr. J. Rollin Slonaker, Dr. James Perrin Smith, Dr. Chester Stock, Dr. Wm. A. Setchell, Dr. George C. Peirce, Prof. Bailey Willis, Prof. Charles E. Weaver, Mr. Clarence A. Waring, Prof. John O. Snyder, Dr. William E. Ritter, and probably others. On the evening of April 7, a dinner was given under the auspices of the Academy at the Sutter Hotel in San Francisco to the members of the Association. The attendance was good and the occasion proved a very pleasant one. The membership of the Academy has also been active during the year in war work, many members being members of various committees of the Pacific Coast Research Conference, through which they are assisting the State Council for Defense in all possible ways. PUBLICATIONS BY THE MUSEUM STAFF The members of the Museum staff have been active in re- search and scientific investigation. Their contributions to scientific literature have been very creditable both in number and quality, as evidenced by the following list of titles: Dickerson, Roy E. 1.

SPECIAL ENDOWMENTS URGENTLY NEEDED The regular income of the Academy is far from adequate to meet our present and increasing needs. Only by practising the strictest economy, limiting expenses in most departments to the minimum requirements, foregoing much field work that really ought to be done now before changing conditions make the problems more difficult or impossible of solution, refraining from the purchase of specimens and publications which are seriously needed, and limiting the personnel of the Museum to the lowest possible needs, have we been able to get along. One of the best ways to remedy this situation and enable the Academy greatly to increase its usefulness in its scientific and educational activities, is by gifts of money to be invested as permanent endowments the incomes from which to be used for certain specified purposes. 344 CALIFORNIA ACADEMY OF SCIENCES (Proc. 47H Ser. Among the special endowments which the Academy would especially commend to those who have prospered in this world _ and who desire to do something that is worth while, the follow- ing may be mentioned : 1. Lectures.—Attention has already been called to the need of a small endowment for public lectures (page 337). An en- dowment of $10,000 to $20,000 would meet this need very well. 2. Publication —The amount which the Academy can devote to the publication of scientific papers is far from adequate. We are compelled to decline every year to accept for publication important contributions to knowledge, by members or friends of the Academy, the publication of which by the Academy would add materially to its prestige in the scientific world. Fortunately we have the John W. Hendrie endowment of $10,000, the income from which is used in publishing scientific papers. But this fund is not enough. We should have another publication endowment that would yield an annual income of anywhere from $1000 to $3000. 3. Ornithology.—The problems of scientific and economic interest connected with a study of the ornithology of the coun- tries bordering on the Pacific and the islands in the Pacific are numerous, important and fascinating. No more enticing field exists. Any one who will give to the Department of Orni- thology a small endowment to be used in the scientific and eco- nomic study of our birds will be rendering a real public service. 4. Mammalogy.—What has been said regarding an endow- ment for the study of birds applies with equal force to mam- mals. A similar endowment for this department is very much needed. 5. Educational Extension Endowment.—I have on former occasions called attention to the “N. W. Harris Public School Extension of Field Museum of Natural History” and the splen- did work it is doing for the children of Chicago. Mr. Harris gave to the Field Museum the sum of $250,000, the income from which is devoted to educational work such as only a museum can do. There is no good reason why some public spirited citizen of California who loves children and who wishes to help them should not give the Academy a like sum of $250,000 for the same purpose. Vos VII] EVERMANN—DIRECTOR’S REPORT FOR 1917 345 6. Library.—The entire library of the Academy was lost in the fire of 1906. Through the generosity of other institutions and of friends of the Academy a very creditable library has been built up in the last 12 years. But the income of the Academy does not permit a growth of the library commensu- rate with the Academy’s needs. A great library of the natural and physical sciences should be built up in San Francisco. An endowment of $200,000 would make this possible. May we not hope that this need will appeal to some one who is able and willing to do this splendid thing for San Francisco and the state ? 7. Exploration of the North Pacific.—In my report for 1914 attention was called to the importance of exploration and in- vestigation of the North Pacific. This should be a compre- hensive physical and biological survey. It should include all the problems of oceanography, meteorology, zoology, botany, ethnology and anthropology connected with the North Pacific. This would be a big undertaking and would require a big en- dowment, but the problems are many and stupendous in their scientific and practical importance. It can be underaken only with large funds and would never be completed in all its phases; hence the need of a permanent endowment. sie fc V C hieagoricy.c 2 aye kone os ae Sao eae ae eae 147 Arnold Arboretum, Jamaica Plain, Massachusetts ........... 137 Colleseof Hawan Honolulussscnohs shoe cxecteoeted ecnale ols 590 In return for these and previous distributions, there have been received by exchange the following: Arnold PAE HOneE IM: sat scene ced cubs Attest ere Kuars lotsa wieaee eel nae 585 Glokeys ray Wri cin I rete ered teenie” al ieee wes eden aie a 22 Gray.

Sixty-three people gave botanical specimens whose names and number of specimens will appear on the list of accessions. A botanical excursion was made in April to the Grand Canyon and over the Apache Trail from Phoenix to the Roosevelt Dam. The specimens collected, representing 349 numbers and numerous duplicates, have not yet been fully studied and are still unmounted and not incorporated in the herbarium. They will form the basis of a paper on the flora of the Grand Canyon which I hope to prepare. In July Mr. and Mrs. Charles E. Miller invited me to accompany them on their yacht “The Yankee” to Santa Cruz and Santa Catalina islands. Owing to the extreme dryness of the season the collection of 165 numbers consisted chiefly of the woody plants since there was scarcely even a trace left of the herbaceous vegetation. Mr. Wm. F. Herrin invited me to a week-end trip to Shasta Springs in September, and even at that late time 79 numbers were added. Another week-end trip in October to the Pinnacles in San Benito County as the guest of Mr. and Mrs. G. Earle Kelly added 38 woody plants to the collection and some duplicates. VoL.

DEPARTMENT OF ENTOMOLOGY By E. P. Van Duzee, Curator The present report covers the activities of the department of Entomology for the year 1917-1918. In my report for last year it was stated that the most urgent duty of the curator during the year would be the classification and arrangement of the North American material now in the Academy collection, and this aim has been constantly before me during the year now closing. It is true that but a start has really been made but that little has done much to increase the value and usefulness of the collection. All of the Coleoptera, or beetles, have been assorted into families and a considerable portion of the Diptera and Hymenoptera, the work in the latter order having been done for us by Prof. J. C. Bradley of Cornell University. In the determination and arrangement of the material in the various families of insects that have been assembled we have been fortunate in securing the assistance of a number of specialists all of whom have given their time and labor without material recompense. Dr. Frank E. Blaisdell has worked up three families of beetles including over 2300 specimens and has five smaller families now in his hands, work on which is well advanced. Mr. Ralph Hopping has attended to two families numbering 650 specimens; Prof. H. C. Fall of Pasadena, one family of about 300 specimens, and Prof. Wickham of Iowa State University, one of 70 specimens. In the Hymenoptera, Prof. J. C. Bradley has worked up most of the aculeate forms, or the wasps, numbering 667 specimens; Mr. Dickenson of Sacramento has studied one family of the Diptera, the Syrphide or flower flies, numbering 554 speci- mens; Prof. J. M. Aldrich of Purdue University 27 specimens of kelp- flies, and my brother, M. C. Van Duzee of Buffalo, the Dolichopodide, 77 specimens. In the Lepidoptera Dr. R. Ottolengui of New York has studied and returned to us the Plusiini, a small group of brightly colored owlet moths, recorded last year as having been sent to him for study. Many scattering determinations have been made in other families of in- sects by myself and others which have done much to enhance the value of 350 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4tm Ser. the collections of the Academy, and considerable routine work has been done in the mounting and labelling not only of accumulated material already in the collection but also of that collected by the curator in his field work and a portion of that received by gift from others, in which work the department has received efficient help from Miss Alma Krauss of Oakland who has acted as departmental assistant at intervals during the past year. Accessions to the department of Entomology for the year number 23,696 specimens, of which 6518 were obtained by the curator in his field work and 17,178 were received by gift from various friends of the institution. This presented material includes several collections worthy of special men- tion. Most valuable of all is the series of 7662 insects, mostly western Lepidoptera, presented by Mr. F. X. Williams formerly of San Francisco but now of Honolulu. The butterflies and moths in this collection were largely determined by specialists and it is, with perhaps a single exception, the most valuable collection of Lepidoptera on the coast. Another fine collection of butterflies and moths, numbering 1737 specimens mostly de- termined by specialists, was presented by Mr. E. J. Newcomer of Palo Alto. Other notable additions to the department are a collection of about 500 microscopic slides of Japanese plant-lice, containing a considerable number of types, determined and presented by Prof. E. O. Essig of the University of California; a collection of about 2400 California He- miptera accumulated and presented by Mr. W. M. Giffard of Honolulu; about 1700 insects presented by Dr. Frank C. Clark of Los Angeles; and nearly 500 beetles received from Dr. Frank Daggett of the Los Angeles Museum of History, Science and Art. In the line of publications the curator has to report the completion of his Catalogue of the Hemiptera of America North of Mexico, a work of over 900 pages issued by the University of California as one of their series of semi-centennial publications, and a report on the collection of California Hemiptera made by Mr. Walter M. Giffard already mentioned. This report includes the descriptions of 50 new forms the types of which have been placed in the collections of the Academy. The field work of the curator during the past year included one week at Bradley and Bryson in Monterey and San Luis Obispo counties, and four weeks in southern California where work was done at Coachella, Palm Springs and Colton, and at San Jacinto, Soboba Springs, and Keen Camp in the San Jacinto Mountains. In addition, single days were spent at Los Angeles, on Mt. Wilson, and Mt. Diablo, and at a few localities about San Francisco Bay. Probably the most important work demanding attention in this depart- ment for the coming year is the classification and arrangement of the col- lection of butterflies and moths, of which the Academy now has a really fine series. The basis of the Academy’s collection in this order will be the Williams material already mentioned. Determinations in the other insect orders will also be pushed as rapidly as possible, for not until this material is worked up can our collections be made available to the sys- tematists of this country, or in the preparation of ecological and systematic groups for public exhibition. Vou. VII] EVERMANN—DIRECTOR’S REPORT FOR 1917 351 DEPARTMENT OF HERPETOLOGY By John Van Denburgh, Curator At the beginning of the year 1917 the Academy’s collection of reptiles and amphibians numbered 33,816. There have been added during the year 1635 specimens, so that we now have 35,451 specimens. A few specimens have been received as gifts, a few more in exchange, but by far the larger number have resulted from field work carried on by the members of the Department in various parts of California. Thus, 1519 specimens have been collected in this state, while only 116 have originated elsewhere. The California specimens have been secured in 18 counties as follows: RantraGoctay muta ssiat 4. cilids eo qctaern es anes cose hes 66 specimens ERG Aida om Ath SS ne Ae tables ew eh al et ik les 26 & NES AGIMENCS. basset Ses St dec Abparsis isin cea a aikters axle ae 1 # NE Cis tan tests oryas dese cere ORR ae 2 s IU UGSELELO: ChE 110 ee NR ee A aa 29 ie IGE Re Vere tic ec tn Ree aber ice ei oan d aie Nere ve 43 Sai COT UG (ap ge Oe Ts NO ay Se en A 387 $s SET G1] 5:5: 01110 em ae gaa Une ee ee 2 © Satie ermandingy srt 56 stich bd via vcs HG ato 814 Sate RAnelSe Ginn Arie set votes hs odin erate ewcl ee eae 2 s Sat OAMUMANE Laces cise hve Ne susan cage omar 4 ae Salo nisObisho cece. mel oars sic arses aren oom we 122 * Sanveviateos.s 5 uatmind ghee wenn wee creer cee 74 Ny SCALE GA ECE lire ee eg Sei. ar ENR A CRP OM OREO tet 6 s IS KANOU Te cise, cas kt ies Senge prs NG yA) el 7 § SOLEMN Om gees Marre teee Ren Nal ae ee tm. are ON 1 e SOMGIaDN Are ote sete ire ra cette Seto aa te ete cet a kee 4 s VED i are a ecttn oicte 5.

These specimens include 1333 lizards, 90 snakes, 29 turtles, 39 frogs, 25 toads, and 3 salamanders. The classification and arrangement of the collection was continued during the year, with the necessary separation, identification, rebottling, labeling and card-cataloguing of the specimens, The collection of lizards is now nearly all classified and arranged and much progress has been made with the snakes. Considerable research work has been done during the year. The gopher and garter snakes of the Pacific States have received especial attention and a number of new facts regarding them have been discoverd which will be published later. In this connection we have been enabled, through the courtesy of Dr. Gilbert of Stanford, and Dr. Grinnell of the University of California, to make use of several hundred snakes belonging to those institutions. Two papers were published during the year; one on the reptiles of Guam, and the other concerning the soft-shelled turtle Aspidonectes cali- forniana. It is hoped that the field work of the department in its survey of the reptiles of the Pacific States may be continued with increasing vigor during the coming year. Much work along these lines yet remains to be done, especially in Oregon, California and Arizona. The number of specimens added during each of the past six years has been about as follows: TAS Arte era A beg aegis ace aCe eR ae 3500 specimens TESTS Sie RN aI SOLE ey see gree Ae Ge 2700 i IST: DROIT Sect PEt ey a arg EVE Oo ao a PE 800 s: MONS eae mete Rech Bettas cu eset Mie A hey te ae ses 800 oe ONG be fee 8 sete ace ee Rhee Sm ae te ee eet cae niet laetala ane 1500 LOS on ce Bist ROL EAE SNS Meas SNe eR ae wane hima No 1600 DEPARTMENT OF INVERTEBRATE PALEONTOLOGY By Roy E. Dickerson, Curator With an increased appropriation for field work, clerical assistance and equipment the department has been able to accomplish some very neces- sary field work in southern California and in Sonoma County. Laboratory studies on the Eocene and Oligocene of Peru, an upper Pleistocene fauna near Tomales Bay, the fauna of Carrizo Creek beds of San Diego County, descriptions of species of Martinez and Tejon Eocene of California and some lacustrine species from the Petaluma lake beds, are now in course of preparation. All of the marine shells of the Hemphill conchological collection have been numbered and placed in cabinet cases or exhibited. The gastropods have been systematically arranged in cabinet cases and work upon the pelecypods is progressing. A portion of a large loan collection from the California State Mining Bureau has been arranged and numbered. The type specimens have been segregated. The curator has been very efficiently aided in this work by Mr. John Carlson and Mr. Georges Vorbe. New fossils of upper and lower Eocene age from the Simi Hills are being described by the curator. These forms are unusually well preserved wo Vou. VII) EVERMANN—DIRECTOR’S REPORT FOR 1917 353 and they will add some information as to the life of the Eocene in the southern part of the state. A general report upon the geology and paleontology of the Marysville Buttes, an ancient volcano of the Sacramento Valley, is in course of preparation. Mr. Clark Gester, geologist, Standard Oil Co., is preparing a geological and stratigraphic report upon a portion of the Peruvian coast and the curator is contributing the paleontological data upon this interesting field. A portion of these rocks are upper Eocene in age while the rest of the tertiary sandstones and shales are Oligocene or Miocene. The study of the molluscan fauna of the Carrizo Creek beds, San Diego County, has already yielded some interesting results in showing that we have a fauna upon the present Pacific Coast whose affinities are Atlantic. This fauna was also collected from sandstones in San Gorgonio Pass by Mr. Frank Vaughan. Dr. L. F. Noble and the curator hope to find some stratigraphic connections between these beds and the lJandlaid deposits of that region during the next year. Geological mapping in the Santa Rosa and Petaluma Quadrangles has progressed during the past year and an excellent Pliocene fauna from Wilson’s ranch in Santa Rosa Valley was obtained. As noted above, con- siderable paleontological information has been obtained as well. Dr. L. F. Noble of the U. S. Geological Survey and the curator spent six weeks in the field in southern California in an elongated area extend- ing from Tejon Pass to Cajon Pass in the San Andreas Rift Zone. Much new information concerning the type of faulting and its topographic expres- sion along this famous rift was obtained. A stratigraphic relation between the Santa Margarita, marine upper Miocene of the Pacific Province and the landlaid deposits which are apparently Barstow Miocene of the Great Basin Province, was discovered and their essential synchrony proved. The geological and paleontological history of this portion of southern Cali- fornia is of particular importance not only to the student of geology but to the naturalist who desires to study the distribution of plants and animals, because his problems are peculiarly tied to the past in this region of great recent mountain building. Some field work is yet to be completed in this interesting region. Mr. F. M. Anderson is preparing a report upon the paleontology and stratigraphy of the northern Colombian coast, South America. This work is particularly important, for rarely in the Antillean Province can satis- factory stratigraphy be obtained, but Mr. Anderson’s work will aid greatly in solving some of the problems of the Caribbean. The curator and other members of the Academy have prepared and published within the year a number of papers and reports based on the department’s collections. These are listed in the President's report. Many kind friends of the Academy have made donations during the year. The most important accession is a loan collection of fossils from the California State Mining Bureau. This collection has much valuable reference material in it and many of Dr. J. G. Cooper’s type specimens have been segregated. A detailed list of donations is set forth in the Director’s report. 354 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4TH SER. DEPARTMENT OF INVERTEBRATE ZOOLOGY By W. K. Fisher, Curator Field work was done at three places on the Pacific Coast. Mr. and Mrs. T. S. Oldroyd made an extensive collection of marine invertebrates at Friday Harbor, in the region of Puget Sound, Wash- ington. Shore forms and those occurring in moderate depths were taken. In cooperation with the University of Southern California a dredging trip was attempted in the vicinity of Santa Cruz Island, with their dredg- ing boat, the Anton Dohrn. Owing to unfortunate accidents to machinery and cable this did not result in many specimens. In lieu of these, the University of Southern California substituted a number of duplicates from their general collection. A little collecting was done in June at Monterey Bay by Mr. A. W. War- nock and the curator. Report OF THE LIBRARIAN FOR 1917 By Edward P. Van Duzee, Assistant Librarian The work done in the library during the past year has been largely of a routine character, although some advance has been made toward render- ing the main collection of books more available to the student. The series of periodicals and society publications in foreign languages have been collated and arranged alphabetically in the lower library room and the shelves properly labeled so these sets are now as readily accessible as are those in the English language in the main reading room. One hundred and twenty-six lineal feet of shelving have been added in the reading room, all but the lowest and uppermost of which have supplemental shelves inter- polated, this portion being used for the temporary shelving of current serials, thus making it more convenient for students to learn what has been published recently that may be of interest to them. In the lower library room 128 lineal feet of shelving have been erected for geological publications, and in the store room 416 lineal feet for duplicates and other reserved material. Additions to the library during the year number 749 bound volumes and many excerpts and other pamphlets which have not yet been acces- sioned but many of which are of much value. These accessions are in addition to the periodicals and society publications received by exchange and from other sources. In planning for another year it seems very desirable that an assistant be made available for at least a part of the time to attend to the acces- sioning and cataloguing of the departmental collections and of books added during the year as well as to keep up certain routine work connected with the care of the main library, and that a reasonable sum of money be set aside for the binding of serial sets that are liable to loss and mutilation in their present form. It also seems proper that something be allotted to the departmental libraries for the purchase of books, as scientific workers are placed at a serious disadvantage if unable to procure certain books important to the problems they may have in hand.
