Few areas of like size in the country have been more thoroughly studied ornithologically, and the records go back for more than a century. When Coues and Prentiss published the first com- prehensive work on the birds of Washington in 1862, a list that was revised and enlarged in 1883, the area surveyed was almost entirely within the District of Columbia. But as the city has grown the birds have been pushed farther from the center, and trolley lines and later automobiles have given easy access to a larger territory so that for some years the present limits have been generally understood. . In this region 301 species and subspecies of birds have been found, and 109 of these breed. | This region lies wholly within the Carolinian zone, and the edge of the Piedmont plateau crosses it several miles west of the city. It is neither possible nor desirable at this time to attempt a complete description of the topography of the country. Excellent accounts will be found in the “‘Avifauna Columbiana”’ by Coues and Prentiss, and in McAtee’s “ Nat- ural History Sketch of the District of Columbia.’’! It does, however, seem desirable to describe some of the localities inter- esting from the ornithologist’s standpoint and to point out some of the changes that have taken place. Many of the localities mentioned by Coues and Prentiss, and by Mrs. Maynard in 1898, as especially good for birds 1Bull. I, Biol. Soc. Wash., 1918, 142 pp., with map. 1—Proc. Biot. Soc. Wasu., Vou. 42, 1929. (1) 2 Proceedings of the Biological Society of Washington. are now solidly built up and native species have been excluded. When Mrs. Maynard wrote, what is now Florida Avenue was the city boundary to the north and Chevy Chase and Takoma Park were small settlements set down in the midst of woods. About that time a trolley ran from Chevy Chase Circle to Glen Echo. Service was discontinued about 1904, but the right of way was passable for about ten years after, and the route was a favorite bird-walk. Many localities where much collecting has been done in the past have been largely abandoned because of changes or be- cause others seemed better. Accessibility has often been a determining factor in the choice of locality and certain areas have been well worked to the exclusion of others, perhaps as good, but less well known. Among the places that have been largely abandoned are Laurel and Marshall Hall, Md. The valley of the Patuxent in the vicinity of Laurel, near the eastern limits of our area, was a favorite collecting ground in the eighties and nineties and many important finds were made there. Marshall Hall, the former home of Chief Justice Marshall, near our limit down the river, has been easily accessible by boat for many years. Several of the earlier collectors did considerable work there and it was the locality treated in “Birds of a Maryland Farm” (Judd, Bull. 17, Biol. Surv., 1902). The Eastern Branch, or Anacostia River, is the largest con- fluent of the Potomac and flows through a part of the city. While its valley is not so good for birds as formerly, the marshes and wooded hillsides along Eastern Branch are still the resort of many species. There are large areas of wild rice which attract Bobolinks and ducks in fall. These marshes above Anacostia Bridge and those on the Virginia side of the Potomac below Key Bridge are the only places within the District of Columbia where hunting is allowed. A section adjoining Eastern Branch, including what are known as Licking Banks and Mt. Hamilton, is to be reserved as a National Arboretum. This region, which is very good for winter and early spring birds, has yielded many specimens important to the Washington list. Rock Creek, another branch of the Potomac, also flows through the city and its valley from the District Line nearly to the river is now a park, much of it left almost in its original Cooke—Birds of the Washington, D. C., Region. 3 state. In spite of the great numbers of people who use the drives and bridle paths, the wooded and brushy areas of this park furnish shelter for many birds, including the Hooded and Kentucky Warblers. The National Zoological Park is a section of this valley, and, though the city has so encroached on its environs as to make it disappointing to persons who knew it in its more primitive state, its easy accessibility is a decided asset and it is still possible to find some of the rarer migrant warblers here in spring. In May, 1922, many persons visited this park to make the acquaintance of the Evening Grosbeak on its only recorded visit to Washington. Takoma Park and the valley of Sligo Branch nearby were until recent years woodland, but a growing suburb has caused the destruction of much of the woods, though many birds still frequent the region. The same general statement may be applied to the vicinity of Forest Glen and Chevy Chase. The Soldiers’ Home grounds with their fields and open woods, though now almost within the city, give shelter to many birds. Bobolinks come here in spring and the Short-billed Marsh Wren was found here in 1927, the third definite record for Washington. The Maryland shore of the Potomac, at least the upper part, has been less worked than the Virginia side, because it was less easy of access. For a few years a trolley ran to Great Falls on this side, but service was discontinued about 1920. This shore is neither so precipitous nor so picturesque as the other. The Chesapeake and Ohio Canal parallels the river and its towpath is a good place from which to observe birds for the trees and bushes between the canal and the river attract many species. About ten miles above the District Line is Plummers Island, the home of the Washington Biologists’ Field Club. On this high island of some dozen acres a cabin was built in 1901 and the island and about forty acres of the adjacent mainland between the river and canal are carefully preserved. This area and the adjacent Virginia shore have been under con- stant observation by some of the keenest field men in the country and many important records have been the result. Two miles below Plummers Island is the famous Cabin John Bridge spanning the lower part of Cabin John Run. 4 Proceedings of the Biological Society of Washington. This easily reached spot provides great diversity of country within a small radius, the trees and bushes of the ravine and adjacent canal bank and above open fields. But here again real estate development is encroaching. The river bank and towpath from Cabin John to Chain Bridge have been and still are among the best places about Washington for the average bird student. Below Chain Bridge the river bank is low and practically within the city. The Virginia shore of the Potomac is a favorite resort of nature lovers for its beauty as well as for its bird life. For the latter the several sections are attractive at different seasons. About 1905 a trolley line from Georgetown to Great Falls opened up this country several miles back from the river, but this line reaches the river only at its terminals. The immediate vicinity of Great Falls is more interesting scenically than ornithologically, and since it has been made an amusement park is good principally as a point of departure. From a point several miles above Great Falls, nearly to the city, the Virginia shore of the Potomac is a series of wooded, sometimes precipitous, bluffs broken by deep ravines. This shore is a north slope and especially good for the latter part of spring migration. Between Difficult Run and Dead Run, a distance of about four miles, is some of the heaviest timber to be found near Washington. Nearly every stream here has a few pairs of Louisiana Water-thrushes, a Pileated Wood- pecker is occasionally seen, and here the Worm-eating and Kentucky Warblers are at home. In this region are the only native hemlocks about Washington. But unfortunately settle- ment is encroaching even here, and the wilderness is in danger of being destroyed. The shore, for about a mile above the Key Bridge (which replaces the old Aqueduct Bridge, so named because at one time the canal was carried across the river at that point), used to be a favorite birding ground, but in recent years quarry- ing operations and settlement have spoiled it. The shore below Key Bridge, once a favorite hunting ground, is at present occupied by the building of the new Memorial bridge to Arling- ton. i | : . The section known as Alexander Island about the south end of Highway Bridge (which replaces the historic Long Bridge) Cooke—Birds of the Washington, D. C., Region. 5 has always been a Mecca for bird students and especially in the last fifteen years since many other easily accessible places have been spoiled. Besides being the most readily reached from the city, the marsh here is one of the easiest in which to observe birds, for railroad tracks afford access to its very edge. But, alas, it is rapidly being filled in asa dump! This “island”? has been the source of many exceptional records for the region, such as the nesting of the Bittern, Virginia Rail, and Florida Gallinule. This is the favorite resort of © the southern herons and the bars off Gravelly Point at the lower end have yielded many shorebird records. At the upper side of this land lies Columbia Island, a raised mud flat that has been formed by dredging operations, and has replaced in part the Analostan Marshes, favorite and popular shooting grounds of a generation ago. This has proved a great attraction to shore birds, and here the Knot was added to the Washington list in May, 1926. About a mile and a half below the bridge lies the mouth of Four Mile Run, where extensive mud flats are exposed at low tide. The stream flows through low, wooded hills and the section has been a favorite with collectors and others. Many important specimens have been collected here, such as the Ruff, Western Sandpiper, and Newfoundland Crossbill. This spot, too, has been considerably spoiled by the destruction of much of the woods and the building of car barns and rail- road yards near the stream’s mouth. Just below the city of Alexandria, Hunting Creek (sometimes called Big Hunting Creek) empties into the Potomac. At the mouth it is about a half mile wide and is a favorite resort for ducks. The country from Hunting Creek to Mount Vernon, a dis- tance of about eight miles, has been for many years a favorite resort for bird-lovers, for nearly all sections are easily accessible from the trolley. The country adjacent to the station of Dyke, about midway, has been especially thoroughly worked, because the protecting hills on the north and the open river to the south make a favorite retreat for winter birds, and many species are first found here in spring. The variety of country, wooded, swampy river bottom, wooded hillsides, and open fields makes it a good place for birds at any time. For 6 Proceedings of the Biological Society of Washington. nearly twenty years the Audubon Society has been going here for one of its spring outings. Here the Prothonotary Warbler has been seen many times and in 1928 was found breeding. The woodland between Little Hunting Creek and Mount Vernon is another favored spot, especially for warblers in early May. Here again is a combination of dry and swampy wood- land and open fields, and there is the added charm that it is about the least spoiled woods within easy reach of the city. About four miles below Mount Vernon on the next penin- sula, is the Fort Humphreys reservation, where the mixed woods are favored by the birds. Here a Pileated Woodpecker is sometimes seen. ‘The valley of Dogue Creek which separates the two points has been found good for birds both in winter and spring. A few places back from the river should also be mentioned. Munson Hill, about five miles west of Long Bridge on the road to Falls Church, a favorite collecting ground of some of the older ornithologists, is no longer visited. Fort Runyon which appears on the labels of many old specimens was about where the Arlington Junction station now stands. Arlington National Cemetery is a good place for birds at. any season of the year. In the vicinity of the Mansion are many evergreens and huge oaks and some shrubbery. In other sections there are bushy woods, swampy tangles, and open fields. In May this is a fine place to find migrant warblers and thrushes. Adjoining the cemetery on the east the Gov- ernment Experimental Farm affords large open fields such as are liked by Vesper and Savannah Sparrows and Horned Larks. In the past century numerous organizations have at various times been engaged in gathering data on the bird life of the region. The first scientific organization of Washington was the Columbian Institute for the Promotion of Arts and Sciences, ! established in 1816 and chartered by Congress in 1818 for a period of twenty years. While this organization established a small general museum, it paid little attention to birds. The National Institution for the Promotion of Science (later changed to the National Institute) was organized in 1840 “‘to promote science and the useful arts, and to establish a national museum of natural history, etc.’”’ This organization which 1See Rathbun, R., Bull. 101, U. S. Nat. Mus., 1917. ; Cooke—Birds of the Washington, D. C., Region. t had much to do with shaping the Smithsonian Plan, and for a time had oversight of the government collections housed in the Patent Office, gathered together considerable collections among which were many birds. These collections together with those of the Columbian Institute, which had been acquired in 1841, were later deposited in the National Museum. In the ‘Bulletin of Proceedings”? (published 1840-46) are to be found the first records of some of the rarest species on our list. In 1856 the Potomac-side Naturalists’ Club was organized. For many years this had a rather informal organization, but in 1875 headquarters were established at the Franklin School where subsequent meetings were held. Here a collection to illustrate the natural history of the District of Columbia was started, but apparently little was done. In July of that year the publication ‘‘Field and Forest’’ was started, which ran for three volumes to June, 1878. In this were published notes on birds of the vicinity and Jouy’s ‘‘Catalogue of Birds.” The Potomac Valley Ornithologists’ Club (1892-96) had a membership of the active ornithologists of Washington. They issued no official publication but some of the results of their activities were published by the individual members in ‘‘The Auk.” In 1897 the Audubon Society of the District of Columbia was organized and has since been an important agent in the study of the local avifauna. The following spring a study class was formed, for several years limited to teachers but later (1903) opened to the public and still continued. Four years after its organization, in 1901, the Audubon Society began holding field trips on the four Saturdays in May and subse- quently two trips in April were added. Members of the Biological Survey have often served as leaders on these trips, which have proved a great stimulus to bird study about Wash- ington. Through these trips and the efforts of individual mem- bers, close watch has been kept on the movements of the birds (especially in spring) for the past twenty years. Since 1902 the Biological Survey bas made a special study of the local birds. As a consequence its distribution files now 1Bull. 101, U. S. Nat. Mus., pp. 1-3. Goode, G. Brown. Report of the Nat. Mus. for 1891, p. 273. 8 Proceedings of the Biological Society of Washington. contain several thousand records pertaining to this region and extending over a period of nearly a hundred years. These records have been the basis of three previous papers on the local avifauna published in the Proceedings of the Biological Society of Washington. . In the preparation of the present paper the writer has had access to some sources of information which were not. available when the previous one was written, and many somewhat ques- tionable records have been traced to their sources. ‘This has changed the status of some species and has resulted in relegating six species to the hypothetical list. It has also seemed advis- able to discard some of the older records since they were of birds purchased in market, and there is no definite evidence of local origin. The writer has followed William Brewster’s excellent rule that the presence of a species in a locality outside its normal range and difficult to identify should depend on a well-authenticated specimen and not on personal opinion. Exception has been made in the case of three species not far from their normal range which have been seen on more than one occasion, and by several competent observers. In 1921 the list was given as 299 species and subspecies, 2 hybrids, and 2 hypothetical forms. The present paper adds seven forms (besides the Northern Robin previously included tentatively) all of which have been published elsewhere, and one hybrid. Six species included in the previous list are here transferred to the hypothetical list and the Audubon Shear- water is restored, making a net increase of two species. Of the 301 species and subspecies and 3 hybrids that have defi- nitely been found about Washington, three, the Heath Hen, Passenger Pigeon, and Carolina Paroquet, are now extinct or extirpated. Of the 109 species that breed more or less regu- larly in this region, 40 may be considered as permanent resi- dents. The Washington region is a meeting ground of northern and southern forms, the latter rather predominating. Considerable change has been noted in the local avifauna in the past forty years, some real and some only apparent. The real changes include both decreases and increases; the former due principally to the growth of the city, driving many birds from their former haunts; the latter due, in part at least, Cooke—Birds of the Washington, D. C., Region. 9 to Federal protection. Many species now seem much more abundant than formerly, but in many cases, especially among the breeding species, this seeming increase is largely due to a better knowledge of their habits and haunts resulting from the much greater number of observers constantly afield. Of the purely accidental occurrences, such as sea birds blown in by storm, there have been very few in the last thirty years. Gulls and terns have everywhere increased in abundance since they have been protected and the effect has been notice- able in the Washington region. The Herring Gull, called rare by Coues and Prentiss, is now a common winter visitant. The Laughing Gull has again become abundant on its coastal breed- ing grounds and a regular summer visitant to Washington instead of a rare straggler; practically the same is true of the Common Tern. In the case of the two latter species it must be remembered that not only have the birds actually increased in number, but there are now many more observers capable of identifying them in the field. Some species of ducks have shown a gratifying increase since the abolition of spring shooting, but this alone can not account for the return to the Potomac of some species, notably the Canvasback, which in very recent years has changed from a rare species to one of the most abundant. Until the last three or four years observations have been mostly confined to the shore between Washington and Mount Vernon. A great many of the ducks raft well out in the river where they can not be seen from shore, or opposite sections where it is impossi- ble to get to the shore. Since the fall of 1925 parties from the Biological Survey have been making trips by boat from time to time to study the ducks. They have found that about Occoquan Bay and Craney Island (a tiny islet about twenty miles below Washington) large numbers of ducks congregate, and that certain species, notably the Gadwall, previously rare, are there in some numbers. Also many ducks are found be- tween there and Widewater, about twenty miles farther down, including some of the sea ducks rarely reported for our area. Therefore, it is quite likely that some of the species that winter in the lower Potomac wander within our limits more frequently than the definite records indicate. The Wood Duck is the only species known to breed within 10 Proceedings of the Biological Society of Washington. our territory. Crippled ducks sometimes remain in the river throughout the summer, and individuals found very much later or earlier than normal may safely be considered of this class. The southern herons have noticeably increased in numbers, in late summer, frequenting principally the marshes about Gravelly Point and below Anacostia. Until quite recently there have been few easily accessible localities attractive to shorebirds and consequently compara- tively little attention has been paid to them. In the last dozen years dredging operations have caused the formation of mud flats which (especially that known as Columbia Island) have proved attractive to shorebirds and have shown that our knowledge of them in this vicinity is very imperfect. Many observers pay little attention to the latter part of spring migra- tion and stop bird-hunting as soon as the warblers have all been recorded. Until quite recently the river shore has been visited principally for early migrants and deserted after the first week in May. Im the last half-dozen years Alexander Island and adjacent regions have been visited off and on throughout May and early June with the result that there has been a great increase in the number of records of species pre- viously considered extremely rare or accidental. Some species, such as the Stilt and White-rumped Sandpipers, thought to be only casual, are apparently tolerably regular migrants over this region, for they drop in whenever condi- tions are right. Several times in recent years heavy rains in late summer or fall have left pools which have remained for some days. Whenever this happens mixed flocks of shore- birds are soon seen around them. In October, 1924, pools near the tourist camp in East Potomac Park attracted some eight or ten species, including the Stilt, White-rumped, and Red-backed Sandpipers. Following the great storm of August 11 and 12, 1928, pools stood for several weeks on the golf course of East Potomac Park, in the Monument grounds, and in the large excavation on Fourteenth Street for the Depart- ment of Commerce building, all of which were soon found by the waders. It was a strange sensation to observe rare shore- birds only a block from Pennsylvania Avenue, one of the busiest streets of the city. The various observers found in Cooke—Birds of the Washington, D. C., Region. 11 “Hoover Lake” (as this excavation came to be known) fifteen species of shorebirds, including such rarities as the Knot, Sanderling, Black-bellied Plover, and Ruddy Turnstone. At the golf course in Potomac Park nineteen species were noted, all the common species, those above mentioned, and the Do- witcher, previously known from only two records. Also a pair of Blue-winged Teal and a flock of five Pintails frequented the pool. All of the Raptores are decidedly léss common than formerly, due in part to cutting down of woods but also, especially in recent years, to the misguided efforts of certain persons who think the extermination of hawks a desirable achievement. Many late migrants seem much rarer than they really are because of the difficulty of seeing them. Frequently by the second week in May when the bulk of the warblers and thrushes are going through, the trees are in full leaf and the identification of warblers in their tops is almost impossible. Seasons when late frosts have retarded the vegetation have often proved wonderful warbler years. Such was the case in 1907 and in 1917 when many records, especially for departure, were broken. The height of the migration for passerine birds is about the 10th to the 12th of May. The great bulk of the warblers come with the Bay-breast around May 10th. In several recent unusually cold springs birds have been scarce because they banked up in the South and then went through so quickly that only the persons fortunate enough to be afield on a par- ticular day saw any great number. Unfortunately, in our local observations, too much em- phasis has been placed on the first one seen and too little atten- tion paid to bulk arrival and the waves of migration. In the case of species which winter in small numbers, such as the Myrtle Warbler and Hermit Thrush, the first ones seen in spring are usually birds which have wintered, and few records have been kept of the arrival of the migrants. Also, in the case of species that have been classed as permanent residents, because a few are present at all times, such as the Field Sparrow and Bluebird, little attention has been paid to the passage of migrants. Records of fall migration are comparatively scarce. Many persons do not realize that fall migration begins in July and 12 Proceedings of the Biological Society of Washington. that many of our local breeding birds are gone by the middle of August. Moreover, the taking of observations during the late summer and fallis not easy. Besides the heat and chiggers, in many places, easily visited in spring, the vegetation (includ- ing catbriar) at that season is so dense as to be almost impene- trable. The workers in the older organizations were primarily col- lectors, recording few observations beyond the specimens taken. Toward the close of the last century the opera glass began to take the place of the gun as a means of observation, to be later superseded by the higher powered prism binocular which makes possible the identification in life of birds that previously could not be seen. The advantages of this change for the study of habits, etc., are too obvious to need explanation. Also it has led to a great increase in the number of persons making observations, and the volume of notes for the past twenty years far exceeds that for the fifty years previous. It also puts upon the compiler the onerous burden of judging the reliability of some of these records, never a pleasant, and often a very difficult task. The bird-student of Washington has an unusual opportunity of getting trained assistance in the pursuit of his hobby. The classes of the Audubon Society offer a chance to study speci- mens of local birds and the outings to observe the birds in life under capable instructors. At the National Museum, besides the general collections, is a special exhibit showing nearly all the species that occur in the region. This exhibit, under the direction of Dr. Paul Bartsch, is constantly being improved and made of greater interest to the student. Here and at the Public Library and its branches tables are posted each spring showing the progress of the local migration. These show the regular and extreme dates of arrival and departure, and the date of arrival for the current year as each species is recorded The Audubon Society, in cooperation with the Public Library, has published a handbook of the literature on birds that may be consulted at that library. In the Library of Congress and the libraries of the Department of Agriculture and the National Museum is a wealth of ornithological literature. The student who wishes to go more deeply into the subject may also con- Cooke—Birds of the Washington, D. C., Region. 13 sult the study collections of the National Museum and the distribution files of the Biological Survey. In the following annotated list of species the order and nomenclature of the third edition of the A. O. U. Check-List and supplements has been followed. In this list and in the table of migration the arithmetical average date of arrival and departure is not to be taken too seriously. At best it can be only a general guide as to when the species may be expected. If a species arrives within two or three days, either way, of the ‘‘average” date it can certainly be said to have arrived ‘“‘on time.’’ In the case of species usually arriving between April .25 and May 5, in a majority of years they will arrive within this normal, but the earlier migrants are quite irregular. The dates of last seen are subject to great variations because such records are difficult to obtain and because weather con- ditions greatly affect the departure of migrants. A couple of hot days may send practically all the migrants north early, while protracted cold may cause them to remain far beyond their accustomed time. Good examples of the latter condi- tion were seen in the springs of 1907 and 1917. In the former year the early spring was rather ahead of the average, but a hard frost on May 10 was followed by cool weather throughout the remainder of the month. In 1917 there was no pronounced cold wave but the weather remained unusually cold throughout May and in both years many records for departure were broken. Fall records are subject to even greater irregularity than those for spring, due in part to the greater influence of the human equation. : Our knowledge of the breeding of our local birds is very incomplete, but personal experience of the difficulty of finding such information has convinced the writer that it would be - worth while to give even the few available data. These have been drawn from the files of the Biological Survey and the egg collection of the National Museum. It is hoped that the bird students of Washington will report their records to the Biological Survey, including data on breed- ing habits, in order that our knowledge of the local avifauna may be kept as nearly up to date as possible. To the many bird students about Washington who have from time to time reported their finds to the Biological Survey, 14 Proceedings of the Biological Society of Washington. I make grateful acknowledgment of their assistance. Many of their names appear scattered through the text as authority for special records. There are some to whom I am especially indebted for their help in the preparation of this manuscript. Dr. Charles W. Richmond kindly turned over to me all his manuscript notes on our local birds, prepared in the early 90s, which have proved very useful, and he has also helped in the finding of old records. Dr. Alexander Wetmore, besides allow- ing me the free use of his personal notebooks, has given much kindly advice and has read and corrected the manuscript. Mr. Frederick C. Lincoln has been ready at all times to answer questions and to give encouragement and advice, as has also Mr. Edward A. Preble, who has besides critically read the entire manuscript. ANNOTATED LIST OF THE BIRDS OF THE WASHINGTON REGION. HoLBOELL’sS GREBE, Colymbus holboelli (Reinhardt). Occasional visitant for which there are few definite records. November 4, about 1850, about 1859 (Spec. in Nat. Mus.); September 30, 1877 (W. F. Roberts); March 26 and December 2, 1916 (L. D. Miner); 2, March 8, 1921 (P. Bartsch). HorneED GREBE, Colymbus auritus Linnaeus. Winter visitant, not uncommon. September 26, 1925 (Katharine H. Stuart), to May 23, 1927 (W. H. Ball); average, October 28 to April 28. PIED-BILLED GREBE, Podilymbus podiceps (Linnaeus). Tolerably common migrant, and possibly occasionally winter visitant, though there is no definite record between December 22 (1927) and February 22 (1922). Birds seen in June in several years are probably non-breeding individuals. One seen, apparently a migrant, July 15, 1899 (E. A. Preble). Spring: February 22, 1922 (J. Kittredge, Jr.), to May 15, 1920 (Mrs. C. A. Aspinwall); average, March 28 to May 3. Fall: August 21, 1894 (E. J. Brown), to December 3, 1921 (J. Kit- tredge, Jr.); average, September 11 to November 2. Common Loon, Gavia immer (Briinnich). Rare winter visitant. October 25, 1887 (E. J. Brown), to June 2, 1907 (A. K. Fisher); average, November 4 to May 12. Cooke—Birds of the Washington, D. C., Region. 15 RED-THROATED Loon, Gavia stellata (Pontoppidan). Casual winter visitant for which there are few definite records. One caught in a gill net at Marshall Hall in the spring of 1882; October 20, 1889, one captured near Ft. Washington; November 15, 1892, a speci- men taken at Glymont, Md. (Wm. Palmer); October 30, 1904, one at Plummers Island (A. K. Fisher); April 17, 1928, two on the Tidal Basin, one captured alive next day (W. H. Ball). Brunnicu’s Murre, Uria lomvia lomvia (Linnaeus). An accidental visitant which has occurred only once, seven specimens having been secured. Five specimens were purchased in market between December 14, 1896, and January 1, 1897, which careful questioning revealed had been shot between Washington and Alexandria. One was shot by a gunner at Occoquan Creek December 20, 1896, and another caught about the same time near Kensington. Guaucous GULL, Larus hyperboreus Gunnerus. Accidental visitant, two records within the city limits. Although specimens were not taken, the circumstances of both records, birds seen well by men familiar with the species in the north seem to justify its inclusion in our list. One seen over the Tidal Basin April 5-9, 1914, and identified by E. A. Preble, J. T. Nichols, J. M. Johnson, and C. H. Rogers. One seen at Gravelly Point February 20, 1920, identified by F. Harper, watched for some time through x8 glasses; seen also by Preble, Wetmore, and Bailey. It was seen again the next day by Miss Marion J. Pellew. On February 18, 1926, one was seen near Quantico, Va., by Preble and Oberholser. The Glaucous Gull is said to have become a regular winter visitor to the New York City region in recent years, so it may be expected to wander occasionally to our area. Herrine Gut, Larus argentatus Pontoppidan. A common winter visitant, more abundant than formerly, as are all the gulls. October 16, 1919 (J. Kittredge, Jr.), to May 20, 1917 (A. Wetmore); average, November 5 to May 6. A specimen in the National Museum was taken August 19, 1865. RING-BILLED GULL, Larus delawarensis Ord. A common spring and fall migrant, a few sometimes remaining through- out the winter. Spring: Latest, June 1, 1928 (W. H. Ball); average, February 25 to May 11. Fall: Earliest, August 20, 1927 (A. Wetmore); average, October 8 to November. 16 Proceedings of the Biological Society of Washington. Laueuine Gui, Larus atricilla Linnaeus. Regular summer visitant, more frequently seen in late summer. It was formerly considered a rare straggler in the vicinity of the city, though probably a fairly regular visitor as far up the river as Marshall Hall. In the last ten years its occurrences have so increased in frequency that it has ceased to be rare. . It breeds commonly on the coast and like all the gulls has greatly increased under protection. Large flocks are sometimes seen. In spring it has been observed from April 26, 1923 (Miss M. J. Pellew), to May 22, 1923 (M. J. Pellew), and in fall from July 18, 1927 (W. H. Ball), to October 30, 1927 (A. Wetmore). Birds, probably non-breeders, have been seen in June, BoNAPARTE’S GuLL, Larus philadelphia (Ord). Common migrant, occasionally winters in small numbers. ~ Spring: Latest, June 2, 1927 (W. W. Rubey); average, April 6 to May 12. Fall: Earliest, August 23, 1928 (W. J. Whiting); average, October 18 to December 2. Cougs’ Caspian TERN, Sterna caspia imperator (Coues). Casual in migration, more frequent in spring than in fall. Two October 4, 1896, brought in flesh to the National Museum; eight May 11, 1917 (F. Harper); one May 5, 1918, near Plummers Island (A. Wetmore); one April 26 and two April 27, 1923 (Marion J. Pellew); seven May 21, 1927 (W. W. Rubey); one June 24 and four June 28, 1927 (H. G. Deignan); two June 29, 1927 (Mrs. T. M. Knappen); one April 26 and four May 20, 1928 (W. H. Ball); five May 12, 1928 (H. H. T. Jackson); one August 14, 1928 (Ball); one October 13, 1928 (Jackson). Forstrer’s Tarn, Sterna forsteri Nuttall. The first record of this species was of a specimen taken near Georgetown in the summer of 1875 by P. L. Jouy. There was also a specimen in the National Museum collected in August, 1859, supposed to have been from this vicinity. Nothing further was heard of this tern until the fall of 1928 when it was fairly common off Hains Point. It was first noted Sep- tember 13 by W. J. Whiting and last on October 26 by Ball and Whiting. The largest number seen together was thirty-seven, on October 9. On October 11, sixteen were seen and three collected by F. C. Lincoln.! Common Tern, Sterna hirundo Linnaeus. Tolerably common in migration, formerly considered very rare or ac- cidental. Like the other gulls and terns this species has increased under protection. Also there are now more observers capable of identifying it in the field. In 1861 Coues and Prentiss called it ‘‘occasional visitor 1One seen December 28, 1928, (W. H. Ball). Cooke—Birds of the Washington, D. C., Region. 17 during the late summer and early fall months.” Since 1917 it has been reported almost every year, more frequently in spring than in fall. In the fall of 1928 with other water birds it was unusually common. In spring it has been noted in 9 years from April 24, 1918 (R. W. Moore), to June 3, 1928 (W. H. Ball); in fall in 5 years from August 20, 1927 (A. Wetmore), to October 31, 1920 (J. Kittredge, Jr.). One record in winter, two seen December 23, 1918 (McAtee, Preble, and Wetmore). Least Tern, Sterna antillarum (Lesson). Accidental visitant, of which two specimens have been taken. One shot at the carp ponds which were formerly west of the Monument, August 17, 1878, by Mr. Hamilton, and in the National Museum. Another specimen in the museum was taken about 1879. There are breeding colonies on the lower Potomac. Buack Tern, Chiidonias nigra surinamensis (Gmelin). Tolerably common fall migrant, and apparently becoming of more fre- quent occurrence in spring. The first spring record was May 3, 1917 (Dyke, M. T. Cooke), and since then it has occurred in Spring in four different years. Records in spring are from May 3 (1917), to May 26 de It was also seen June 29, 1927 (Knappen). . Fall: July 12, 1926 (Miss M. J. Pellew), to September 22, 1894 (Has- brouck Aya Wm. Palmer); average, August 17 to September 14. AUDUBON’S SHEARWATER, Puffinus lherminieri Lesson. Following the great storm of August, 1842, a shearwater was captured in the District of Columbia. Coues and Prentiss in both their lists record it as doubtfully referred to Puffinus obscurus, the name then used for the present species. In his monograph of the family, however, Dr. Coues says: ‘“The species of Puffinus spoken of in a paper published by Dr. D. W. Prentiss and myself in the Annual Smithsonian Report for 1861, p. 418, as having occurred at Washington, D. C., and doubtfully referred to as the obscurus, has since been definitely rege ad to be this species.” (Proc. Acad. Sui. Phila., 1864, p. 138.) The specimen can not now be found, but in view of Dr. Coues’ statement it seems that it should be included in the list, and not considered: hypo- thetical as was done in the list of 1921 when the author did not know of the above statement On November 27, 1884, on the Potomac off Ft. Foote, Dr. H. M. Smith saw a bird so closely as definitely to identify it as a shearwater, but the species was not determined. Leacnu’s PETREL, Oceanodroma leucorhoa (Vieillot). An accidental visitant that has occurred four times. One (not 4 as given in former list) in August, 1842, following a severe northeast storm. 18 Proceedings of the Biological Society of Washington. Two, o and 9, taken about 1859 (spec. in Nat. Mus.). One, probably this species, seen at close range in January, 1878, by William Palmer. ‘One shot near Navy Yard Bridge June 7, 1891 (spec. in Nat. Mus.). HawallAN PETREL, Oceanodroma castro (Harcourt). Accidental visitant. One was shot from a flock of 3 or 4, August 28, 1893, following a severe storm along the south Atlantic coast. Another was captured in a house on Capitol Hill where it had taken refuge. Both specimens were in the collection of William Palmer and constitute the first record for North America. Wiuson’s PETREL, Oceanites oceanicus (Kuhl). Accidental visitant which has occurred three times: one taken after the hurricane in August, 1842; one about 1859 (spec. in Nat. Mus. received from ‘‘Master’’ Bender); one taken near Marshall Hall, June 27, 1914 (in Nat. Mus.). DOUBLE-CRESTED CORMORANT, Phalacrocorax auritus auritus (Lesson). Casual visitant, mostly in spring and early summer. Fall 1842 (National Institute); 1859 (C. Drexler); July 19, 1884 (Wm. Palmer); November, 1884 (spec. B. Steinmetz); April 19, 1896 (Bendire and Fisher); several May 11-20, 1917 (various observers); June 12, 1921 (W. L. McAtee); May 31, 1922 (Miss M. J. Pellew); April 7, 1925 (H. C. Oberholser); May 13, 1926 (A. Wetmore); June 1 and 2, 1927 (W. W. Rubey); June 27, 1927 (Mrs. T. M. Knappen); June 1, 1928 (W. H. Ball). AMERICAN WHITE PEuican, Pelecanus erythrorhynchos Gmelin. Accidental visitant, four specimens; one in the District in 1863, and one near Alexandria in April, 1864, both immatures shot by C. Drexler, and in the National Museum; one shot opposite Washington in the autumn of 1864, and one near Alexandria in October, 1878, specimens known to Smith and Palmer. AMERICAN MERGANSER, Mergus americanus Cassin. Winter visitant, fairly common on the Potomac, most numerous below Indian Head. It is sometimes seen in the Washington harbor. October 13, 1889 (B. Greenwood), to May 26, 1905 (H. C. Oberholser) ; average, October 29 to April 27. | One seen near Four Mile Run on July 27, 1927, was probably a crippled bird. RED-BREASTED MERGANSER, Mergus serrator Linnaeus. Tolerably common winter visitant. All migration records are for recent years. It is frequently seen in the Tidal Basin. October 31, 1920 (J. Kittredge, Jr.), to May 30, 1927 (W. H. Ball); average, October 29 to April 30. Cooke—Birds of the Washington, D. C., Region. 19 HoopEep MeraanseEr, Lophodytes cucullatus (Linnaeus). Winter visitant, tolerably common, found most frequently in the creeks tributary to the Potomac. October 1, 1889 (B. Greenwood), to May 11, 1917 (F. Harper); aver- age, October 21 to April 14. Ma tuarp, Anas platyrhynchos Linnaeus. Common winter visitant. Seen more commonly on the Potomac below Fort Washington, and most numerous from Occoquan Bay to Cherry Hill. August 20, 1927 (Preble and Wetmore), to May 14, 1922 (J. Kittredge, Jr.); average, September 24 to April 24. Rep-Leccep Biack Duck, Anas rubripes rubripes Brewster. This northern race is abundant in winter but most observers do not distinguish it from the other form. March 25, 1917 (specimens, F. Harper); April 21, 1918 (Harper). Buack Duck, Anas rubripes tristis Brewster. Abundant winter visitant, and perhaps a very rare summer resident, since it is found only a short distance outside our limits. On January 5, 1925, one was shot on Eastern Branch that had been banded September 29, 1922, at Lake Scugog, Ontario. Several others banded at the same station have been taken within our area. August 1, 1887 (A. K. Fisher), to June 1, 1928 (W. H. Ball); average, _ September 17 to May 3. GADWALL, Chaulelasmus streperus (Linnaeus). Winter visitant. This species probably shows the most radical change in distribution of any in our area. Formerly of very rare occurrence it has within the last five years increased until now it is common in migra- tion and tolerably common throughout the winter, at least just below our area, on the Potomac. One was taken from a flock, August 24, 1884 (Thos. EN The latest record in spring is May 8, 1924 (A. Wetmore). They begin to arrive in numbers after the middle of September, and increase to the middle of November; then the numbers greatly decrease until late February or early March. The bulk leave in March. EuropeEAN WipGEon, Mareca penelope (Linnaeus). Accidental visitant for which there are three records. Specimen taken near Alexandria and bought in market by Drexler, spring, 1863; another taken on the Potomac River near Washington, October 16, 1892, was also purchased in market. A specimen was collected near Aquia Creek, about forty-five miles below Washington, December 24, 1927, by U. T. Brooks, and now in the National Museum. 20 Proceedings of the Biological Society of Washington. BALDPATE, AMERICAN WipGEoN, Mareca americana (Gmelin). Tolerably common winter visitant, more numerous in migration. Most commonly seen between Fort Washington and Quantico. Arrive in October; earliest, September 4, 1905 (B. Greenwood); and leave by early April; latest, April 21, 1928 (L. D. Miner); average, April 5. EuROPEAN TEAL, Nettion crecca (Linnaeus). Accidental, one record, a specimen in the National Museum, was taken on the Potomac River near Washington in April, 1885. GREEN-WINGED TEAL, Neittion carolinense (Gmelin). Formerly a common fall migrant, but now rather rare; casual in winter; very rare or accidental in spring, only two records. Since 1905 it has been recorded in only five years. Spring: March 11, 1852 (spec. in Nat. Mus.); March 31, 1918 (L. Griscom). Fall: September 18, 1903 (B. Greenwood), to November 15, 1902 (Greenwood); average, October 4 to November 7. Eight seen December 238, 1926 (A. Wetmore). BLUE-WINGED TEAL, Querquedula discors (Linnaeus). Common migrant, less commonly seen on the open river. This has been called a wintering species, but the records do not bear this out; there are no records of its occurrence from the middle of December to the middle of March. Spring: March 12, 1922 (J. Kittredge, Jr.), to May 11, 1917 (H. C. Oberholser); average, March 21 to April 20. Fall: August 7, 1928 (W. H. Ball), to December 10, 1927 (H. H. T. Jackson); average, August 30 to November 1. One seen June 2, 1892 (Wm. Palmer), was very likely a cripple. SHOVELER, Spatula clypeata (Linnaeus). Rare winter visitant, more frequently recorded in fall migration. Spring: Has been recorded in three years, March 24, 1918 (L. Griscom) ; April 2-9, 1922 (J. Kittredge, Jr.); March 30, 1926 (H. C. Ober- holser), to April 17, 1926 (W. H. Ball). Fall: In eight years has been reported from September 17, 1911 (W. L. MecAtee), to December 16, 1920 (F. C. Lincoln). One winter record, January 20, 1923 (A. Wetmore). AMERICAN PintTatL, Dafila acuta tzitzihoa (Vieillot). Common winter visitant, both in the Potomac and in the smaller streams and marshes. It is rarely seen in large flocks. August 27, 1928 (A. H. Howell, 4 in a rain pool on the golf course, Potomac Park), to May 14, 1922 (J. Kittredge, Jr.); average, Oc- tober 3 to April 15. June 17-23, 1927, a pair, apparently not crippled, was seen in the Alexander Island Marsh (H. C. Oberholser). Cooke—Birds of the Washington, D. C., Region. 21 Woop Duck, Aix sponsa (Linnaeus). Tolerably common in migration; a few breed. This has been listed as a permanent resident, but it is very doubtful if it occurs in winter at the present time. Fifty years ago it was seen principally in winter but, even in the days of its general abundance, was never a common species in this region. In recent years there have been no certain records in winter. Nesting begins early in April, for young about two weeks old were seen May 30 (1897). Spring: Arrive about the middle of March; earliest, Pebnuiey. 22, 1860 (spec. in Nat. Mus.). Fall: Leave about the first of November; latest, December 10, 1927 (H. H. T. Jackson). REDHEAD, Marila americana (Eyton). -Common winter visitant, but very irregular in abundance. Found commonly between Fort Washington and Aquia Creek and large flocks farther down the river. October 5, 1901 (B. Greenwood), to April 21, 1912 (W. D. Appel); average, October 13 to March 285. CanvasBack, Marila valisineria (Wilson). Very abundant winter resident. This is one of the species that has recently greatly increased in numbers. Early accounts of the ‘District of Columbia refer to this duck as enormously abundant in the river as far up as Georgetown. In the time that Coues and Prentiss were writing, they had ceased to be very abundant and by 1900 were rather rare and remained so until less than ten years ago when they began to come back. September 10, 1922 (J. Kittredge, Jr.), to April 21, 1928 (W. H. Ball); average, October 17 to April 1. Birds seen during the summer are either cripples or non-breeding individuals that failed to migrate. GREATER Scaur Duck, Marila marila (Linnaeus). Both Scaups winter in abundance, but it is seldom possible to distinguish between them. The Greater is much less common. In 1881 a female, undoubtedly crippled, bred near Mt. Vernon (Richmond, Auk, V, 1888, pe. £8); September 26, 1920 (J. Kittredge, Jr.), to May 27, 1906 (H. C. Ober- holser); average, October 22 to May 12. Lesser Scaur Duck, Marila affinis (Eyton). Very abundant winter resident. This is much the more abundant of the two Scaups and is found on the Potomac in large rafts. Non-breeding individuals often remain quite late in spring, and birds, probably cripples, have been seen throughout the summer. September 25, 1903 (B. Greenwood), to June 3, 1928 (W. H. Ball); average, October 13 to May 19. 22 Proceedings of the Biological Society of Washington. RING-NECKED Duck, Marila collaris (Donovan). Rather rare migrant, and occasionally occurs in winter. Seen on the river chiefly between Indian Head and Occoquan. Spring: Latest, April 13, 1926 (E. A. Preble); average departure March 30. Fall: Earliest, October 6, 1901 (B. Greenwood); average arrival, October 21. One was seen May 12, 1928 (H. H. T. Jackson). AMERICAN GOLDENEYE, Glaucionetia clangula americana (Bonaparte). Common winter visitant, confined to the river and its larger tributaries. Often seen in the river near the city. October 8, 1901 (B. Greenwood), to April 27, 1918 (F. Harper); aver- age, October 26 to April 2. One, probably a cripple, May 12, 1922 (A. Wetmore). BUFFLEHEAD, Charitonetia albeola (Linnaeus). Tolerably common winter visitant. It has apparently somewhat in- creased in abundance in the last dozen years. Coues and Prentiss called it common, but there are very few definite records previous to 1916. Records range from November 26, 1922 (J. Kittredge, Jr.), to May 1, 1928 (W. J. Whiting). The majority of the records are in March and April. Oxtp-squaw, Clangula hyemalis (Linnaeus). Rare winter visitant. A sea duck, wintering commonly on Chesapeake Bay, it is possible that it wanders to the edge of our region nearly every winter, but seldom gets farther up the river. November, 1842 (reported to the National Institute); April 15, 1881 (S. F. Baird); November 20, 1884 (H. W. Henshaw); April 3, 1889 (J. D. Figgins); October 20, 1889 (Wm. Palmer); April 20, 1896, on Rock Creek near Kensington (J. D. Figgins); November 6, 1915 (F. M. Weston); April 21, 1917 (F. Harper); March 4, 1921 (J. Kittredge, Jr.); January 20, 1923 (A. Wetmore); six March 9, 1925 (H. C. Oberholser); December 7, 1926, March 16 and 30, 1927 (Moody Creighton); March 13, 1928 (H. H. T. Jackson). On June 16, 1897, George Marshall found one in worn plumage on a lake near Laurel; it had not been there a few days previous. AMERICAN E1pER, Somateria dresseri Sharpe. Accidental visitant, only one record. A specimen taken at Pomonkey Neck below Marshall Hall was in the collection of the Maryland Academy of Sciences. AMERICAN ScoTER, Oidemia americana Swainson. All three Scoters occur regularly in winter in Chesapeake Bay, but seldom ascend the Potomac River as far as Washington. There is only Cooke—Birds of the Washington, D. C., Region. 23 one record for the American Scoter, a specimen in the National Museum taken in December, 1842. WHITE-WINGED ScoTErR, Oidemia deglandi deglandi Bonaparte. This is the least rare of the three species of Scoters. They winter abundantly in Chesapeake Bay and possibly wander up to the Potomac nearly to our limits every winter. December, 1842 (spec. in Nat. Mus.); November, 1880 (ditto); October 14, 1882 (specimen identified by E. Coues); April 18, 1892 (spec. in Nat. Mus); November 8, 1920 (L. Griscom); January, 1925 (M. Creighton); 3, December 10, 1927 and 2 January 24, 1928 (H. H. T. Jackson). One, believed to be a cripple, August 20, 1927 (A. Wetmore). Surr Scoter, Oidemia perspicillata (Linnaeus). Like the other Scoters this is common on Chesapeake Bay in winter, but like other sea ducks seldom wanders up the river as far as Washington. One was reported to the National Institute as having been taken in Febru- ary, 1842; and there are five specimens in the National Museum taken within our area: December 11, 1858; February 19 and April 10, 1859; one about 1859; 1868. Ruppy Duck, Erismatura jamaicensis (Gmelin). Winter visitant, rare in mid-winter, tolerably common in migration, less abundant now than formerly. August 20, 1889 (B. Greenwood), to May 22, 1928 (W. H. Ball); aver- age, September 28 to April 30. Two records in June, possibly crippled birds; June 21, 1877 (Wm. Palmer), and June 28, 1927 (W. H. Ball). CaNnaDA Goose, Branta canadensis canadensis (Linnaeus). Uncommon winter visitant, common migrant in October and February. October 5, 1888 (B. Greenwood), to oe 22, 1890 (H. B. Stabler); average, October 18 to March 30. Brant, Granta bernicla glaucogastra (Brehm). Accidental visitant, one specimen, December 16, 1858, in National Museum. The specimen of January, 1844, previously recorded was taken on the eastern shore of Maryland. WHISTLING Swan, Olor columbianus (Ord). Regular migrant in fall but rare in spring. In recent years a flock has wintered nearly every year at Widewater, Va., about 40 miles below Washington. The earliest date of arrival is October 15, 1901 (B. Green- wood); average, November 6. January 14, 1881, one that had been stunned from flying against a wire was caught in the grounds of the Louise Home at 15th Street and Massa- 24 Proceedings of the Biological Society of Washington. chusetts Avenue. March 22, 1907, a flock of 15-20 was reported below Alexandria, and on April 5 flying over Falls Church (J. H. Riley). A flock of 14 near Alexandria March 17, 1916 (H. H. Bailey), to March 20, 1916 (W. W. Cooke and T. S. Palmer); some in Occoquan Bay, March 28, 1920 (A. Wetmore); large flock over the Tidal Basin, March 27, 1921 (W. W. Rubey); six or seven over Potomac Park, March 29, 1927 (S. F. Blake). Gtossy Isis, Plegadis falcinellus (Linnaeus). There are two records for this species nearly a hundred years apart. The first, about 1817, by Ord is rather doubtful. In September, 1900, one was shot near the city by a hunter who brought it to a local taxider- mist’s shop where it was identified by J. W. Daniel, Jr. Although pub- lished by Ord in 1817 and again by Baird, Brewer, and Ridgway in 1884, - this species was not included in the Washington list until 1898. Woop ate: Mycteria americana Linnaeus. An eeeiontAl visitant from the south which has occurred twice. Two, ad. @ and im. 9, were taken on the flats near the Monument July 2 1892 by Frederick Zeller. In July, 1896, several were reported, and 3 specimens taken, two on July 20 at Silver Hill, Md., brought to Schmid’s Bird Store, and one taken near Laurel, Md., July 27, brought to George Marshall. A daily paper reported two ‘‘white cranes”? over the White House on July 15 and another about that time was reported at Four Mile Run. AMERICAN BitTERN, Botaurus lentiginosus (Montagu). Rare summer resident, more common in migration. In ‘‘Birds of the Northwest”’ (p. 527) Coues says ‘‘I have procured it in January at Washing- ton.”’ Otherwise there is no record of its occurrence between early No- vember and late March, so any wintering must be accidental. This species seems to have increased in abundance; between 1894 and 1911 there are apparently but two records, since the latter date they have been recorded nearly every year. Hard set eggs and also young ready to fly found June 3 (1917). March 22, 1894 (W..Robinson), to November 7, 1860 (E. Coues); average, April 10 to September. Least Bittern, [xobrychus exilis (Gmelin). Summer resident, locally common. They breed rather commonly in the marshes below Alexandria, expecially near Dyke where young have been found in July. April 27, 1922 (M. T. Cooke), an April 27, 1927 (W. W. Rubey), to September 19, 1881 (H. M. Smith); average, May 4 to Sep- tember 5. | 1Since this manuscript was completed a Bittern was seen at Arlington Farm, Decem- ber 3, 1928, by W. J. Whiting. _ Cooke—Birds of the Washington, D. C., Region. 25 GREAT BLUE Heron, Ardea herodias herodias Linnaeus. - This species is common in migration and almost a permanent resident for it is found in every month of the year, but has never been known to breed here, and it is rare in winter. Spring: Average, March 30 to May 26. Fall: Average, August 2 to November 1. AMERICAN EGRET, Casmerodius egretta (Gmelin). A wanderer from the south in the late summer and early autumn. In the early days these herons were tolerably common in summer, but by the time Coues and Prentiss were writing, they had become rare. There is. no record of their occurrence between 1894 and 1912 since which date they have been present nearly every year, sometimes quite a number. They are never so abundant as the Little Blue Heron. They arrive usually from the middle of July to the middle of August; they have arrived as early as June 21, 1927 (W. H. Ball); June 23, 1926 (H. G. Deignan), and June 27, 1925 (L. D. Miner). They remain until about the middle of September, the latest date being October 2, 1923 (S. F. Blake). Two records in May: May 30, 1891 (Wm. Palmer), and May 27, 1926 (Mrs. T. M. Knappen). Snowy Heron, Egretta candidissima candidissima (Gmelin). - An accidental visitant from the south, of which a single specimen is known, taken about 1841 and now in the museum of Oberlin College. It is possible that when this species was more abundant it occasionally wandered to our area, but the majority of the records refer to the Little Blue Heron in the white phase. Louisiana Heron, Hydranassa tricolor ruficollis (Gosse). An accidental visitant from the south. One was found in the Alexander Island marsh August 25, 1922, by Miss Marion J. Pellew, and between then and the 29th was seen by a number of persons. August 30-31, 1926, two others were seen in the same marsh by several persons, and on Sep- tember 21, 1926, perhaps the same two birds were seen at Four Mile Run (W. H. Ball). One was again reported July 17, 19, and 30, 1927, in the same marsh (W. H. Ball). LitTtLeE Buue Heron, Florida caerulea (Linnaeus). A late summer visitant from the south, sometimes in large numbers. Nearly all birds seen are in the white phase. Birds have been seen from June 27, 1925 (L. D. Miner), to October 3, 1925 (H. H. Hazen), and October 13, 1928 (W. H. Ball); average July 29 (19 years) to September 18 (9 years). There is a single spring record of one seen near Miller, Va., May 12, 1917 (Wm. Palmer). 26 Proceedings of the Biological Society of Washington. GREEN Heron, Butorides virescens virescens (Linnaeus). Tolerably common summer resident. Eggs May 3 (1894); young about a third grown June 3 (1888). April 3, 1927 (W. W. Rubey), to October 16, 1923 (C. H. M. Barrett); average, April 19 to September 21. BLACK-CROWNED Nicut Heron, Nycticorax nycticorax naevius (Boddaert). Permanent resident, rare in winter. There seems to be no occupied heronry near Washington at the present time. In the late eighties there was one near Ballston, Va., and one on Hunting Creek. For many years there was one at the east side of the Dalecarlia reservoir at District line; the birds later moved to trees nearer the river, and these were abandoned about 1920. Night Herons sometimes winter in the Zoological Park near the flying cage which contains several individuals of this species, and have been known to nest on the outside of the cage. Nest building begins about the end of March. YELLOW-CROWNED Niaut Heron, Nyctanassa violacea (Linnaeus). Accidental visitant from the south. One taken in the Smithsonian Grounds in August, 1901 (Wm. Palmer). All subsequent observations have been in the marsh at the lower end of Alexander Island. One May 30, 1926, and during July and August by a number of observers; one July 4, 19, and 30, 1927 (W. H. Ball). SANDHILL CRANE, Grus mexicana (Miller). Coues and Prentiss are authority for the statement that this species has occurred once in the region. They record a specimen previous to 1861, Kine Rai, Rallus elegans Audubon. Rare summer resident, occasional in winter, for there are several records for December and one for January 19 (1901). They begin breeding the latter part of May, ten eggs May 30 (1910) to June 18 (1887); downy young, June 23 (1893). Records are too insufficient to determine the migration. CLAPPER Ratu, Rallus crepitans crepitans Gmelin. An accidental visitor from the coast, one record, a specimen taken in the marsh above Long Bridge, September 8, 1882, by Frank Ford. Vireinia Raitt, Rallus virginianus Linnaeus. Fairly common in migration and breeds locally in small numbers. It occurs at all seasons of the year but probably not the same individuals. Eggs have been taken from May 26 (1922) to June 3 (1917). It migrates principally in April and September. Specimens, De- cember 28, 1912 (E. R. Adams), and January 17, 1924 (C. H. M. Barrett). Cooke—Birds of the Washington, D. C., Region. 27 Sora, Porzana carolina (Linnaeus). A regular migrant, seldom reported in spring but common in fall, when they are hunted. An old report says that in September, 1888, over 1,300 were killed in the marshes below Alexandria. Spring: April 1, 1928 (W. H. Ball), to May 21, 1926 (W. H. Ball); average, April 18 to May 13. Fall: July 8, 1918 (R. W. Moore), to November 9, 1878 (S. F. Baird); average, August 12 to October 19. YELLOw Ratt, Coturnicops noveboracensis (Gmelin). Casual in migration, more frequent in fall than in spring. All records are of specimens. Autumn, 1843 (National Institute); October 4, 1879, November 3, 1880, March 28, 1884, April 14, 1893, October 18, 1895, 1896, October 13, 1900, March 12, 1909 (spec. Nat. Mus.); November 17, 1893 (Wm. Pal mer); May 20, 1917 (N. Hollister). Beer Ratt, Creciscus jamaicensis (Gmelin). Rare in migration, occurs regularly in the marshes near Mt. Calvert, Md.

Jones); October 19, 1906; September 22, 1907, and October 12, 1908 (W. F. Roberts); one taken September 1, 1908, on Eastern Branch by H. M. Darling (spec. Nat. Mus.); one seen on Eastern Branch, September 15, 1918 (R. W. Moore); one picked up in Woodridge, May 14, 1923 (E. R. Kalmbach). Fioripa GALLINULE, Gallinula chloropus cachinnans Bangs. Tolerably common migrant; rare and local breeder; all definite breeding records being from the marsh near the south end of Highway Bridge. Seven eggs, incubated about 5 days, were taken there June 3, 1917 (E. J. Court); 8 eggs, similarly incubated, were found May 30, 1919 (Court); 10 eggs, May 11, 1922 (R. W. Williams). In September, 1926, young were seen at Four Mile Run (Ball), and downy young in the Alexander Island marsh in July, 1927, and August, 1928 (Ball and Donoho). The earliest date of arrival is March 29, 1928 (W. H. Ball), and the latest date in fall, October 26, 1876 (Spec. Nat. Mus.). AMERICAN Coot, Fulica americana Gmelin. . Abundant migrant, a few sometimes remaining throughout the winter. In recent years, in late fall and early spring, coots have bedded in great numbers in Occoquan Bay and from there to Quantico, Va. Spring: Latest, June 13, 1926 (W. H. Ball); average, March 25 to May 10. Fall: Earliest, September 1, 1890 (B. Greenwood); average, September 29 to November 10. 28 Proceedings of the Biological Society of Washington. Rep Puauarope, Phalaropus fulicarius (Linnaeus). Accidental visitant, one record; a specimen in the National Museum, an immature taken on Eastern Branch, October 17, 1885, by F. S. Webster. Another specimen was shot October 4, 1897, at White’s ae on tne, Potomac about 40 miles above Wachine on! NorTHERN PHALAROPE, Lobipes lobatus (Linnaeus). Accidental visitant, two records; a specimen in the National Museum taken August 31, 1891, on Navy Yard Creek, and one seen August 29, 1916, on Hastern Branch by R. W. Moore and C. R. Shoemaker. AMERICAN Woopcock, Rubicola minor (Gmelin). Summer resident, now rare; fairly common locally in late summer; possibly sometimes wintering for there are records to the end of December but none in January. Coues and Prentiss mention a number of localities as good for woodcock, where none would be found at present. In,recent years it has been known to breed in Rock Creek Park, near Dyke, and Four Mile Run. It begins to breed about the middle of March; young about a week old have been found April 18 (1897). Eggs have been found late in February when there was snow on the ground. Earliest, February 6, 1916 (E. A. Preble); average, March 8 to No- vernber a, Wison’s Snips, Gallinago delicata (Ord). A common migrant. It is probable that birds occasionally winter, though there is only one record for January. This may be due to lack of observers rather than of birds. | Spring: Latest, May 14, 1910 (W. W. Cooke); average, March 13 to May 3. Fall: Earliest, August 26, 1928 (H. G. Deignan); average, September 9 to November 23. Dow1TcHER, Limnodromus griseus griseus (Gmelin). Accidental visitant. One taken on Analostan Island, September 2, 1878, by W. F. Roberts; two seen July 31, 1928. (H. G. Deignan). Follow- ing the hurricane in August, 1928, two appeared in the pool on the golf course in East Potomac Park where they were observed from August 14 (Howell and Wetmore) to August 29 (Ball). LONG-BILLED Dowi1TcHER, Limnodromus griseus scolopaceus (Say). Accidental visitant. Smith and Palmer record seven specimens secured in April, 1884, on the Eastern Branch. Stitt SANDPIPER, Micropalama himantopus (Bonaparte). An irregular fall migrant which may be less rare than the records indicate. Records are: Two, September 8, 1885, near Laurel (H. W. Henshaw); one, October 26, 1916, on Eastern Branch (F. Harper); one September 6, Cooke—Birds of the Washington, D. C., Region. 29 1918, on Little River (A..H. Hardisty); one September 20, 1923, in west court of National Museum building (P. Bartsch); one October 8, 1924, in a rain pool in East Potomac Park (A. Wetmore); one August 14, 1928, in East Potomac Park (Howell and Wetmore). One spring record, June 3, 1926, at Columbia Island (Ball and Ruppert). Knot, Calidris canutus (Linnaeus). Accidental in migration. It was first recorded for the region in May, 1926, and appeared both spring and fall in 1928. One was present at Columbia Island May 26 to June 3, 1926, where it was discovered by Edmund Platt and W. H. Ball, and was subsequently seen by a number of observers, and an unsuccessful attempt made to collect it. A flock of 15 was seen off Hains Point May 26, 1928 (Knappen and Ball). One was seen in East Potomac Park August 29 and September 3, 1928 (Ball), and two in the excavation at 14th and B Streets, Septem- ber 4 and 10 (Lincoln and Wetmore) to September 12, 1928 (H. G. Deig- nan). PECTORAL SANDPIPER, Pisobia maculata (Vieillot).. Tolerably common migrant, more abundant in fall. Recent observa- tions indicate that our knowledge of its movements in spring are very imperfect, and that the main migration is later than was previously sup- posed. Spring: March 26, 1916 (A. Wetmore), and April 22, 1887 (Wm. Palmer), to June 11, 1926 (W. H. Ball); average, April 23 to late May. Fall: August 10, 1914 (W. W. Cooke), to November 1, 1916 (H. C. Oberholser); average, August 23 to October 15. WHITE-RUMPED SANDPIPER, Pisobia fuscicollis (Vieillot). A very rare migrant which has recently been added to the list. Records are not yet sufficient to determine its status, but it has occurred in four of the last five years, one to four birds being observed each time. October 8 and 24, 1916 (F. Harper); May 11, 1917 (Wm. Palmer); Sep- tember 20, 1918 (A. H. Hardisty); October 3-12, 1924 (A. Wetmore); May 15 to 26, 1926 (various observers); May 12, 1927 (W. H. Ball); August 24 to September 3, 1928 (Ball and Whiting). Barrp’s SANDPIPER, Pisobia bairdi (Coues). An accidental visitant, two specimens, at Four Mile Run, one collected September 3, 1894, by R. S. Matthews (Nat. Mus.); and one taken Sep- tember 25, 1894, by Wm. Palmer. Least SANDPIPER, Pisobia minutilla (Vieillot). Tolerably common in migration, apparently somewhat less abundant than the Semipalmated Sandpiper, with which it is often associated. Spring: April 17, 1926 (W. H. Ball), to June 14, 1926 (Ball); average, April 28 to May 20. 30 Proceedings of the Biological Society of Washington. Fall: July 17, 1927 (Ball), to November 22, 1917 (C. H. M. Barrett); average, August 14 to October 15. RED-BACKED SANDPIPER, Pelidna alpina sakhalina (Vieillot). This is a rare migrant which has been increasingly reported in recent years, and is one of the species that may be looked for whenever there are pools to attract shorebirds. Previous to 1916 there were less than a half- dozen records; since then a number have been observed. Spring records are mostly in late May (11-27) with one for April 22, 1887 (Wm. Palmer). Fall records range from August 14, 1928 (Howell and Wetmore), to No- vember 1, 1916 (H. C. Oberholser). The earliest specimen was taken October 20, 1842, by S. F. Baird. SEMIPALMATED SANDPIPER, Hreunetes pusillus (Linnaeus). Tolerably common in migration. In the autumn of 1928 it was very common in the Department of Commerce Building excavation as well as on the golf course. Spring: May 4, 1927 (W. H. Ball), to June 14, 1926 (Ball); average, May 11 to 27. Fall: July 22, 1927 (Ball), to October 28, 1916 (L. D. Miner); average, August 13 to October 10. WESTERN SANDPIPER, Hreunetes mauri Cabanis. Accidental in fall migration, has been taken in three seasons. The first specimen was taken September 8, 1894 (Wm. Palmer), at Four Mile Run. In the following month over a hundred specimens of small sand- pipers were taken but only three proved to be this species; September 11 (R. S. Matthews), September 14 (E. J. Brown), September 22 (E. M Hasbrouck). Subsequently one was taken August 20, 1897 (Bartsch and Palmer); two September 3, 1897 (Osgood and Palmer), two on Eastern Branch September 25, 1919 (Nat. Mus.); one, September 17, 1926 (P. Bartsch). It sometimes becomes rather common at St. George Island, Md., and on the coast of Virginia. SANDERLING, Crocethia alba (Pallas). Rare in migration. September, 1874, one taken near the Monument (seen by Wm. Pulao : one October 24, 1885 (C. W. Richmond); three seen, one taken at Four Mile Run September 22, 1894 (Wm. Palmer); two at the same place be- tween September 26 and 30, 1898; one at Columbia Island May: 31, 1926 (Ball and Ruppert). In the fall of 1928 there were a number of observa- tions of this species: one July 29 (H. G. Deignan); one at Hains Point August 14 (Ball); one to five August 28 to September 15 at the excavation 14th and B Streets, N. W.; a flock in East Potomac Park September 21 (A. H. Howell); one on the Virginia shore September 27 (F. C. Lincoln). Cooke—Birds of the Washington, D. C., Region. 31 GREATER YELLOWLEGS, Totanus melanoleucus (Gmelin). Tolerably common migrant. Both Yellowlegs frequent grass-bordered pools in preference to mud-flats, but often occur on the flats at Four Mile Run. Spring: April 1, 1928 (M. T. Donoho), to June 3, 1928 (W. H. Ball); average, April 19 to May 17. Fall: July 17, 1927 (W. H. Ball), to November 2, 1919 (J. Kittredge, Jr.); average, August 3 to October 13. LEssER YELLOWLEGS, T'otanus flavipes (Gmelin). Common migrant, much more numerous than the Greater Yellowlegs. In the autumn of 1928 a small flock was frequently seen in a pool in the Monument grounds close to Fourteenth Street. Spring: April 5, 1925 (E. Platt), to May 22, 1926 (M. T. Cooke); average, April 18 to May 13. Fall: July 17, 1927 (W. H. Ball), to November 1, 1916 (H. C. Ober- holser); average, August 20 to October 12. One that had been caught alive by a cat, March 12, 1906, was brought to the Biological Survey for identification. SoLiTARY SANDPIPER, Tringa solitaria solitaria Wilson. - Common migrant. This species is well-named, and is a bird of small pools and the stream banks rather than of the open mud flats. Spring: March 30, 1883 (H. W. Henshaw), to May 21, 1921 (M. T. Cooke); average, April 28 to May 17. Fall: July 15, 1899 (E. A. Preble), to October 28, 1916 (L. D. Miner); average, August 6 to October 4. E. J. Brown took a specimen early in November, 1893. WIiLLET, Catoptrophorus semipalmatus semipalmatus (Gmelin). Rare migrant. A flock of about 50 was reported near Eastern Branch August 10-11, 1893. One shot was secured by Wm. Palmer; a flock of over 30 seen near the same place August 27, 1893 (‘‘Bart”’ in ‘‘Forest and Stream’”’); one May 16, 1917 (Mrs. F. M. Bailey); one June 9-11, 1926, at Columbia Island (Ball et al.); other records without dates. Rurr, Philomachus pugnax (Linnaeus). One of the nineteen specimens of this European species taken in North America was secured by Wm. Palmer at Four Mile Run, September 3, 1894. It was an immature female. UpLAND PLOVER, BARTRAMIAN SANDPIPER, Bartramia longicauda (Bechstein). Uncommon migrant, more frequently noted in fall than in spring. This is a species that has become much depleted everywhere, but seems to be increasing slightly under protection. Coues and Prentiss called this a rare summer resident here. It certainly does not breed within our terri- 32 Proceedings of the Biological Society of Washington. tory at present; the latest record is of a pair that bred near Sandy Spring, Md., about 1900 (fide A. K. Fisher). In July, 1927, Dr. Wetmore saw segeel at Dickerson, Md., and thought that they had bred there that season. Spring: March 21, 1896 (P. W. Shufeldt), to May 11, 1917 (L. D. Miner); average, April 5 to 26. Fall: June 29, 1902 (W. W. Cooke), to September 26, 1919 (A. Wet- more); average, July 15 to August 30. SPOTTED SANDPIPER, Actitis macularia (Linnaeus). A common summer resident, more abundant in migration. It breeds in May, but no data are available. | April 2, 1905 (W. iby McAtee), to October 28, 1906 (A. K. Fisher); average, April 18 to September 28. LoNG-BILLED CurRLEW, Numenius americanus Bechstein. Accidental visitant from the west. A specimen taken on the Potomac April 11, o is in the National Museum. Hupson1an emma! Numenius hudsonicus Latham. This species is abundant in migration along the Virginia coast but has only once wandered up the river to Washington. A flock of eighteen was seen off Hains Point May 26, 1928, by Mrs. T. M. Knappen and W. H. Ball, and a single bird 1 in the same place next day by W. H. Ball and H. C. Oberholser. AMERICAN BLACK-BELLIED PLover, Squatarola squatarola cynosurae Thayer and Bangs. Rare in migration. Three, September 26, 1914 (Nat. Mus.); one Oc- tober 24, 1916 (H. C. Oberholser); one October 26, 1919 (A. Wetmore); one October 3, and two October 4, 1924 (Wetmore and Swales); one May 24, eleven May 26, 1928 (Ball and Mrs. Knappen); one seen on many occasions between August 21 and September 13, 1928, sometimes at the Commerce building excavation and sometimes at East Potomac Park (Lincoln and Ball); six on the Potomac marshes September 27, 1928 (Lincoln). GoLDEN Puiover, Pluvialis dominica dominica (Miller). Accidental in migration. A specimen said to have been taken many years ago by D. W. Prentiss. Following the great hurricane, two were seen in East Potomac Park, September 20, 1928. On October 14, four were seen on the mud bar off Hains Point, three October 16, one October 18, collected, two October 26 (all by W. H. Ball). A specimen in the National Museum was collected by John B. Peyton, March 28, 1911, at Nanjemoy: Creek, Maryland, on the Potomac about fifty miles below Washington. KitLpEER, Oxyechus vociferus (Linnaeus). Common summer resident and a few usually winter. Twenty-five years ago this was a very rare species here, but has gradually increased. Nesting -~Cooke—Birds of the Washington, D. C., Region. 33 begins early in April, if not before, for eggs have been found April 3 (1895) and young just hatched, April 24 (1897). Average dates, March 11 to November 7. SEMIPALMATED PLoveErR, Charadrius semipalmatus Bonaparte. Irregular migrant, more often reported in spring than in fall. Since the marshes have been more carefully watched in late May, there has been a decided increase in the number reported. All early records are of only 1 or 2 birds at a time but since 1923 flocks have several times been reported, usually in late May. In spring they have been noted from April 30, 1926 (W. H. Ball), and May 3, 1884 (Spec. Nat. Mus.), to June 19, 1926, large flocks on Columbia, Island from May 25 to June 19 (Ball). Fall records range from August 14, 1928 (Ball), to October 7, 1924 (Wetmore and Swales). Piping Puover, Charadrius melodus Ord. Accidental visitant from the coast where it breeds, and for which there is but one record for our territory. A specimen taken May 3, 1884, near the Virginia end of Long Bridge by A. Skinner is in the National Museum. Another specimen was taken March 25, 1881, by William Hamlin on the Potomac near Aquia Creek, Virginia, about 15 miles beyond our limits. Ruppy TuRNSTONE, Arenaria interpres morinella (Linnaeus). Rare and irregular in migration, principally in late May and September. Spring: May, 1881 (O. N. Bryan); June, 1882 (J. A. Moore); eight June 3, 1926 (Ball and Ruppert); two May 20-24, 75, May 26, 1928 (Knappen and Ball). _ Fall: One September 2, 1912 (HE. R. Adams); September 7, 12, and 13, 1928 (Ball), September 27, 1928 (F. C. Lincoln). Other records without definite dates. Bos-WuitTe, Colinus virginianus virginianus (Linnaeus). Resident, common. For some years it has been the custom of the D. C. Audubon Society to provide grain for feeding the quail whenever snow endangers them. Through the kindness of the local authorities, this is distributed by the police in the outlying sections, and several times censuses of the quail have thus been taken. Nesting begins early in May, and while only one brood is raised, a female has been found incubating September 16 (1891). Rurrep Grouse, Bonasa umbellus umbellus (Linnaeus). Formerly a somewhat local permanent resident but now nearly extir- pated within our area. According to Mr. L. C. Gunnell it is still found in very small numbers near Bush Hill and Accotink, Fairfax County, Va. Late records from other localities are: two near Falls Church, November 23, 1913 (A. Wetmore); one below Great Falls, Md., February 22, 1916 (W. W. Cooke); one between Contee and Bowie, Md., January 28, 1917 (W. L. McAtee). Adult and young were seen near Dyke in May, 1894 (E. A. Preble). 34 Proceedings of the Biological Society of Washington. -Heata Hen, T'ympanuchus cwpido (Linnaeus). A specimen taken near Washington, April 10, 1846, by Dr. Alex. Me- Williams was formerly in the National Museum (Swales, Proc. Biol. Soc. Wash. XXXII, 1919, p. 198). Witp Turkey, Meleagris gallopavo silvestris Vieillot. Formerly a common resident, now very rare within our limits. There is a small flock near Bush Hill, Fairfax County, Va., and they occur in the Bull Run valley slightly beyond our area. Apparently they remained fairly common in the wilder sections until about 1890. The latest definite date of breeding within our area was of eggs found near Falls Church May 3, 1903 (J. H. Riley). A flock of eleven was seen near Neabsco, Va., December 2, 1928 (B. M. Morgan). PASSENGER PIGEON, Ectopistes migratorius (Linnaeus). Formerly abundant migrant, now extinct; the last large flock was prev- ious to 1860. Subsequent records are: September 18, 1877 (Spec. Nat. Mus.); April 3, 1887 (H. W. Henshaw); September 11, 1889 (W. Palmer); October 19, 1889 (J. D. Figgins); a flock of about a dozen, one taken, near Jefferson, Md., fall of 1889 (J. D. Figgins) ; a small flock, two or three taken, near Laurel, fall of 1889 (Geo. Marshall); one, May 2, 1891 (R. W. Shu- feldt). Movrnine Dove, Zenaidura macroura carolinensis (Linnaeus). Common summer resident and irregular winter resident. A flock of 5 or 6 wintered one year near the bird house at the Zoological Park. Three broods are often raised, eggs have been found from April 6 (1919) to August 11 (1889), and young from fully fledged in nest April 24 (1921) ~ to young just hatched in early September. Average dates, March 17 to November 3. Grounp Dove, Chaemepelia passerina passerina (Linnaeus). An accidental visitant from the south. Two specimens, both females, are in the National Museum, the first taken September 1, 1844, and the other taken at Broad Creek, Md., October 14, 1888. Other dates given in the 1921 list were errors. TurkEey VULTURE, Buzzarp, Cathartes aura septentrionalis Wied. Common permanent resident. Nesting begins usually the latter part of April; but fresh eggs have been found by April 11 (1897) to May 9 (1914); young June 2 (1892). On May 4, 1924, a nest containing three slightly incubated eggs was found (R. W. Williams). Back VULTURE, Coragyps urubu urubu (Vieillot). Casual visitant from southern Maryland. Four March 30, 1895, at Kensington (J. D. Figgins); one July, 1896, at Brookland (A. W. Ridgway); Cooke—Birds of the Washington, D. C., Region. 35 one December 17, 1899, at Congress Heights (P. Bartsch); one February 21 to March 10, 1917, at the Zoological Park around the flying cage (N. Hollister); five, January 2, 1920, near Plummers Island (H. S. Barber); two March 25, 1922, at Laurel (G. Marshall); one October 22, 1924 (W. L. McAtee); one May 14, 1927, at Miller (Audubon Society); one November 6, 1927, at Mt. Vernon, two May 10, 1928, near Dyke (W. H. Ball). The species is established as a breeding bird near La Plata, Maryland, about twenty-five miles south of Washington. SwWALLOW-TAILED KiTE, Elanoides forficatus (Linnaeus). Accidental visitant from the south for which there is one local record and two from nearby points. One observed near the Virginia end of Aqueduct Bridge, April 11, 1897, by Paul Bartsch. One taken in Montgomery County, Maryland (probably within our limits), August 3, 1895, and brought to Schmid’s store. One taken August 7, 1879, near Ellicott City, Md., was sent to the National Museum in the flesh. Mars Hawk, Circus hudsonius (Linnaeus). Tolerably common migrant and winter visitant (much less common than formerly), and a few pairs probably breed, since there are records of birds seen in June and early July, but no record of eggs or young. They arrive in late September and leave in late April. SHARP-SHINNED Hawk, Accipiter velox (Wilson). Common in migration; a few breed, and a few remain in winter. Eggs, May 5 (1894) to 31 (1891); young first week in June (1891). Coorrr’s Hawk, Accipiter cooperi (Bonaparte). Rare resident; fairly common in migration. A pair that nested near Terra Cotta had fresh eggs from April 21 (1918) to May 5 (1922); just hatching May 27 (1919). Young with pinfeathers of wing just showing were found June 15 (1888). AMERICAN GosHAWE, Astur atricapillus atricapillus (Wilson). Rare winter visitant, probably occurring more frequently than the few definite records would indicate. Coues and Prentiss (1883) say that it occurs, but give no dates. One taken at Sandy Spring, Md., December 27, 1887, brought to A. K. Fisher; one caught at Takoma Park, January 1, 1896, brought alive to the National Museum; specimens shot September 1 and 2, 1916, and De- cember 20, 1917, at Beltsville, Md., by T. A. Davis; one seen near Craney Island, February 3, 1927 (H. C. Oberholser). RED-TAILED Hawk, Buteo borealis borealis (Gmelin). Tolerably common winter visitant, formerly rare summer resident, but it is doubtful whether any breed within our area at present. Formerly bred near Sandy Spring, Maryland. 36 Proceedings of the Biological Society of Washington. RED-SHOULDERED Hawk, Buteo lineatus lineatus (Gmelin). - Permanent resident, formerly rather common, but now, like all the hawks, rather rare. For many years a pair nested near Dyke, but they have not been there since about 1924. They have also nested in Glover Park west of Georgetown in recent years. Eggs about to hatch taken April 26 (1891); large young May 9 (1891). BROAD-WINGED Hawk, Buteo platypterus (Vieillot). Summer resident, tolerably common. This has been considered a permanent resident, but since its principal winter home is in South America all winter records, being sight records, are open to question. In April and September large flocks are sometimes seen in migration. Because of the supposition that the species is resident, little attention has been paid to migration dates except the first one seen in spring. Eggs have been taken from April 23 (1893) to May 15 (1897); eggs about to hatch May 20 (1901) and young in nest June 3 (1896). March 31, 1919 (M. T. Cooke); average, April 22 to about the first of October. AMERICAN ROUGH-LEGGED Hawk, Archibuteo lagopus sancti-johannis (Gmelin). Rare winter visitant, probably occurring more frequently than the few definite records would indicate. One about 1859 (spec. Nat. Mus.); one December 29, 1879 (H. W. Henshaw); one winter of 1880 (spec. Nat. Mus.); one, December 23, 1882 (spec. Nat. Mus.); March 17, 1888 (A. K. Fisher); March 25, 1888 (Wm. Palmer); January 1, 1895 (E. A. Preble); December 23 and 31, 1916 (Gabrielson and Kalmbach): January 1, 1918 (A. H. Howell); cember 27, 1925 (A. Wetmore). GOLDEN Eacuie, Aquila chrysaetos (Linnaeus). An accidental visitant from the north. ‘Two specimens in the National Museum taken December 26, 1857, and March 7, 1859. A pair, one of which was taken, occurred near Gaithersburg, Md., December 8, 1887. Several specimens have been taken in Maryland and Virginia a little beyond our limits, some during recent years. BaLp Factz, Haltaeetus leucocephalus leucocephalus (Linnaeus). Permanent resident, more commonly observed in summer. They breed near Mt. Vernon and have bred in recent years near Great Falls where slightly incubated eggs were found February 20 (1897). Duck Hawk, Falco peregrinus anatum Bonaparte. Regular but rather rare winter visitant. One or two frequently winter in the tower of the Post Office Department building. Records of observa- tions of this species about the city range from October 17, 1928 (M. T. Cooke), to May 22, 1918 (L. Griscom). Duck hawks Hage also been seen several times in the neighborhood of Plummers Island. Cooke—Birds of the Washington, D. C., Region. 37 Pigzton Hawk, Falco columbarius columbarius Linnaeus. Rare, probably regular, in migration, but seldom identified with certainty. Spring: March 21, 1920 (J. Kittredge, Jr.), to May 11, 1917 (H. C. ‘Oberholser); average, April 11 to 30. Fall: September 4, 1890 (W. B. Barrows), to November 10, 1891 (Wm. Palmer); average September 12 to October 25. AMERICAN SPARROW Hawk, Cerchneis sparveria sparveria (Linnaeus). Fairly common permanent resident. Eggs from March 31 (1894) to August 4 (1889). Fish Hawk, AMERICAN OsprREY, Pandion haliaetus carolinensis (Gmelin). Fairly common summer resident, a few pairs nest along the Potomac River, especially in the vicinity of Ft. Washington and Mt. Vernon. Nest- ing begins in April. March 19, 1905 (C. R. Ellis), to November 30, 1907 (A. K. Fisher) ; average, April 9 to October 20. One was seen over the frozen river February 1, 1918, near Plummers Island (A. Wetmore). Barn Owt, Tyto alba pratincola (Bonaparte). Uncommon permanent resident. It has nested in the towers of the District jail and in various towers of the Smithsonian Institution, and uses the latter as a winter roosting place. Apparently deceived as to season by the heat from the building, young have been hatched here in late fall and winter. Young just from the nest were seen in the grounds, December 8, 1893, and February 27, 1895 (C. E. Bendire). The latter must have been hatched in late December or early January. Young not over two weeks from the nest were seen January 7, 1896 (A. K. Fisher). On May 11, 1914, a female was found in the northwest tower incubating five eggs (A. Wetmore). They probably breed sometimes in Arlington Cemetery and near Plummers Island, and formerly on Analostan Island. AMERICAN LONG-EARED OWL, Asio wilsonianus (Lesson). Now a very rare permanent resident, formerly fairly common. Like most of the Raptores, it is an early breeder and young about two weeks old have been found April 20 (1890). A recent record is of one taken near Laurel, January 23, 1926. SHORT-EARED OWL, Asio flammeus (Pontoppidan). Rare winter visitant, November to May. In Fisher’s ‘‘Hawks and Owls” eleven specimens from this region are listed, taken between No- vember 22, 1886, and November 20, 1891. Besides these there are about a dozen records, only one since then, March 2, 1913 (A. Wetmore). BarRED Ow1, Strix varia varia Barton. Fairly common permanent resident. Usually begins nesting in March, but eggs have been found as early as February 28 (1897); young on the wing April 28 (1917). 38 Proceedings of the Biological Society of Washington. SAw-wHET Ow.L, Cryptoglaux acadica acadica (Gmelin). Occasional winter visitant for which there are about twenty records, mostly from November to February. One October 3, 1886 (F. S. Webster), and one March 12, 1889 (J. D. Figgins). Recent records are: January, 1914 (R. W. Shufeldt); February 6, 1916 (I. N. Gabrielson); November 30, 1916 (A. K. Fisher); December 1, 1917 (E. A. Sikken); Hate 2, 1928 (D. C. Audubon Society). ScrEEcH Ow1L, Otus asio asio (Linnaeus). Fairly common permanent resident, often observed in the city. For several years one or more roosted every winter in trees in the Agricultural grounds. Incubated eggs April 6 (1899); four young just hatched and one egg April 26 (1891). GREAT HorneD OwL, Bubo virginianus virginianus (Gmelin). Rather rare permanent resident confined to the more heavily wooded sections. Most of the recent records have come from the vicinity of Plummers Island and Fort Humphreys. Young were found February, 1890, near Rockville. Snowy Owt, Nyctea nyctea (Linnaeus). Accidental winter visitant from the far north. A specimen taken December 4, 1858, now in the National Museum was made the type of the race arctica by Mr. Ridgway. About 15 specimens were taken during the winter of 1876-77; November 11, 1885, from Arlington County, Va.; one received in the flesh from Spring Hill, Md., December 30, 1890. A female was killed near Lanham, Md., November 29, 1926, that had been in the neighborhood about a month. CAROLINA PAROQUET, Conuropsis carolinensis (Linnaeus). This species is now extinct. There is one record for the region, a flock in September, 1865, from which several were shot. YELLOW-BILLED Cuckoo, Coccyzus americanus americanus (Linnaeus). Common summer resident, frequently observed in the shade trees of the city during the summer. Eggs May 30 (1894) to September. Young recently from nest August 3 (1919). April 30, 1927 (F. C. Lincoln), to October 18, 1925 (Katharine H. Stuart); average, May 5 to October 5. BLACK-BILLED Cuckoo, Coccyzus erythrophthalmus (Wilson). Fairly common migrant and rare summer resident. Nesting begins about the first of June. April 30, 1928 (W. H. Ball), to October 28, 1925 (L. D. Miner); average, May 7 to September 30. Cooke—Birds of the Washington, D. C., Region. 39 BELTED KINGFISHER, Ceryle alcyon alcyon (Linnaeus). Common summer resident, a few sometimes remain through the winter. Young about ten days old, June 16 and half-fledged young June 24 (1889). Average, March 21 to November 7. Harry Wooppecker, Dryobates villosus villosus (Linnaeus). Fairly common permanent resident, rather local; frequently observed near Plummers Island, Takoma Park and elsewhere. Nesting begins early; birds have been seen apparently beginning to mate February 14 (1915); young just hatched April 9 (1900) and young still in nest June 6 (1926). Downy WoopPEckKER, Dryobates pubescens medianus (Swainson). Common permanent resident. Fully-fledged young May 31 (1914). YELLOW-BELLIED SAPSUCKER, Sphyrapicus varius varius (Linnaeus). Common in migration, tolerably common in winter. September 10, 1905 (W. W. Cooke), to May 20, 1927 (F.C. Lincoln); average, October 2 to April 23. PILEATED WoopPEcKER, Phloeotomus pileatus pileatus (Linnaeus). Very rare permanent resident confined to the heavy timber; probably only two or three pairs left in the region. Recent observations are from the region between Plummers Island and Great Falls and from Fort Humphreys. About 1920 it was known to nest on an island above:Great Falls. At one time it was common in heavy timber near Falls Church, and near Mt. Vernon. RED-HEADED WoopPECKER, Melanerpes erythrocephalus (Linnaeus). Tolerably common summer resident, irregular in winter, some years common, and others almost totally absent. Its presence in winter depends more on the oak mast than on temperature. Birds can nearly always be found in Arlington cemetery and they breed in the Agricultural grounds. This species is less common than formerly, due to the cutting down of patches of oak woods in the course of real estate developments, and probably to the killing of birds by electric power companies. Eggs June 4 (1887) to 23 (1885); young out of nest June 23 (1901). RED-BELLIED WOODPECKER, Centurus carolinus (Linnaeus). Local resident, not common. Several pairs may be found between Oaks and Mt. Vernon, along both sides of the river between Great Falls and Cabin John Bridge, and in the high woods back of Chevy Chase Lake. Apparently somewhat more common than formerly. Young recently from the nest, August 3 (1919). NorTHERN FLICKER, Colaptes auratus luteus Bangs. Common permanent resident, less abundant in winter; abundant in migration. Breeds principally in May and June, fresh eggs from April 29 (1894) to June 13 (1887); small young May 22 (1888). 40 Proceedings of the Biological Society of Washington. Hysrip Fiicker, Colaptes auratus luteus x cafer collaris. An adult male of this hybrid between the yellow-shafted and red-shafted flickers was taken at Laurel about 1880 by Henry Marshall. WHIPPOORWILL, Antrostomus vociferus vociferus (Wilson). Common summer resident. Begins nesting early in May; eggs May 6 (1906) to June 6 (1895). April 1, 1913 (E. J. Brown), and April 1, 1917 (V. Mindeleff), to October 13, 1889 (H. W. Henshaw); average, April 18 to September 20. NiGHTHAWE, Chordeiles virginianus virginianus (Gmelin). Formerly abundant migrant and rare summer resident, now fairly common in summer. This species has greatly increased as a breeding bird in the last ten years especially in the city where it evidently breeds on the roofs of the buildings. No data are available regarding the time of breeding in this area. Spring: Earliest, April 18, 1919 (H. H. T. Jackson); average, May 3 to 25. Fall: Latest, October 13, 1926 (M. T. Cooke); average, August 16 to September 29. CHIMNEY SwiFt, Chaetura pelagica (Linnaeus). Common summer resident and abundant migrant. In fall large numbers use various chimneys about the city as nightly roosting places. Migrants apparently begin to arrive about the middle of August. Nesting does not begin until June and the earliest date for eggs seems to be June 10 (1888). April 5, 1914 (M. W. Curry), to October 25, 1906 (W. W. Cooke), and October 25, 1925 (V. Bailey); average, April 16 to October 12. One was seen over Alexandria, November 19, 1925 (Katharine H. Stuart). RUBY-THROATED HUMMINGBIRD, Archilochus colubris (Linnaeus). Common summer resident. At a meeting of the Potomac Valley Ornithological Club, Prof. Beal reported that about the middle of May, 1895, he saw upwards of a hundred ruby-throated hummingbirds around a horse-chestnut tree in the Agricultural grounds. Two broods are probably raised; eggs May 20 (1896) and young in the nest August 12 (1893). A nest containing three eggs was found at Con- gress Heights, May 28, 1899 (P. Bartsch). April 16, 1912 (W. R. Maxon), to October 20, 1913 Gs K. Fisher); average, May 2 to September 20. KINGBIRD, Tyrannus tyrannus (Linnaeus). Locally common summer resident. Begins nesting about the first of June. April 18, 1914 (E. R. Kalmbach), to September 23, 1905 (F. E. L. Beal); average, April 26 to August 31. Cooke—Birds of the Washington, D. C., Region. 41 ARKANSAS KINGBIRD, T'yrannus verticalis Say. A western species for which we have one record, a specimen taken in Maryland just beyond the District line, September 30, 1874, and found in the market by P. L. Jouy. CRESTED FiycatcHer, Myiarchus crinitus (Linnaeus). Common summer resident. Eggs May 13 (1887) to June 16 (1914). April 19, 1914 (W. W. Cooke), to September 29, 1907 (R. W. Williams); average, April 28 to September 11. PHOEBE, Sayornis phoebe (Latham). Common summer resident, a few may occasionally winter, for there are several records for late December and January. Two broods are raised and possibly sometimes a third. Eggs from April 16 (1925) to June 19 (1889); young on the wing May 10 (1921). Average, March 13 to October 19. OLIVE-SIDED FLycaTcHER, Nuttallornis borealis (Swainson). Very rare in migration, seen more often in spring than in fall. Several in September, 1881, at Falls Church (R. Ridgway); May 9, 1912 (A. K. Fisher); May 22, 1915, at Great Falls, Va. (W. W. Cooke); May 27, 1917, on Eastern Branch (A. Wetmore); two, August 13, 1917, on Eastern Branch and one, September 9 and 14, 1918, at Kensington (R. W. Moore); one May 10, 1919, at Franklin Park, Va. (Miner and Moore); one May 16, 1920, in Cleveland Park (E. A. Preble); one May 22, 1920, near Prospect Hill, Va. (M. T. Cooke); one May 25, 1924, at Takoma Park (A. Wetmore). Woop Preweez, Myiochanes virens (Linnaeus). Common summer resident. Nesting begins about the first of June, and a second brood is probably raised. Eggs have been found June 1 (1887) and young still in the nest August 26 (1895). April 29, 1914 (W. W. Cooke), to October 12, 1906 (A. K. Fisher); average, May 5 to September 20. YELLOW-BELLIED FLycatTcHER, Empidonax flaviventris (W. M. and S. F. Barrp). Tolerably common, but local in migration. This is one of the last species to arrive in spring and frequently slips through without being de- tected. Spring: May 9, 1902 (A. K. Fisher), to June 1, 1917 (F. Harper); average, May 14 to 22. Fall: July 28, 1859 (E. Coues), to October 6, 1881 (H. M. Smith); average, August 15 to September 18. 42 Proceedings of the Biological Society of Washington. ACADIAN FLycatTcHER, Empidonaz virescens (Vieillot). Common summer resident. The earliest record for a complete set of three eggs is May 30 (1896). Fresh eggs are found throughout the month of June. April 25, 1926 (A. Wetmore), to September 15, 1912 (W. W. Cooker and September 15, 1922 a Kittredge, Jr.); average, May 6 to September 7. ALDER FLycaTcHER, Empidonaxz trailli alnorum Brewster. A migrant, apparently rare, though possibly tolerably common; but since it is very difficult to distinguish the Acadian and Alder in life except by their songs, few of the latter are recorded. Spring: May 7, 1922 (H. C. Oberholser), to June 1, 1917 (F. Harper); average, May 13 to 22. Fall: August 16, 1886 (A. K. Fisher), to September 17, 1890 (C. W. Richmond); average, August 23 to September 14. Least FiycatcHer, Empidonax minimus (W. M. and §. F. Baird). Tolerably common in migration. Spring: April 20, 1881 (Wm. Palmer), to May 27, 1917 pee Wetmore); average, May 2 to 17. Fall: August 13, 1887 (A. K. Fisher), to October 1, 1916 (D. C. Mab- bott); average, August 25 to September 13. Hornep Lark, Otocoris alpestris alpestris (Linnaeus). Rare winter visitant. Flocks of Horned Larks are present nearly every winter, but in the majority of cases the race is not determined; alpestris is probably less common than praticola. Undetermined or mixed flocks have been reported from October 26, 1890 (H. B. Stabler), to April 7, 1889 (H. W. Henshaw), but the majority of records are in December and February. Flocks certainly of this race were observed between December 15, 1917, and February 24, 1918 (F. Harper). Prairie HorNED Lark, Otocoris alpestris praticola Henshaw. Irregular winter visitant, probably more common than alpesiris. Very rare summer resident. Young of the year were taken near Laurel, June 23, 1922 (E. B. Marshall), and one seen August 11, 1889 (C. W. Richmond). Other definite records are: February 8, 1881, January 23 to February 16, 1888 (Wm. Palmer); March 1 and 8, 1914 (A. Wetmore); February 10 to 24, 1918 (F. Harper); February 22, 1921 (J. Kittredge, Jr.). BuvuE Jay, Cyanocitta cristata cristata (Linnaeus). Common permanent resident, abundant migrant from late April to mid-May and October. This species has varied greatly in abundance. Coues and Prentiss in both of their lists called it abundant, especially in migration and winter. In the 90’s it was considered rare except in mi- Cooke—Birds of the Washington, D. C., Region. 43 gration. In the last twenty-five years it has greatly increased and is now a common breeding species, sometimes nesting in the shade trees of the city. Two broods are raised, and eggs have been taken as early as April 27 (1913). Crow, Corvus brachyrhynchos brachyrhynchos Brehm. A winter visitant, frequenting the roosts with the Southern and Fish Crows. They have usually left by the middle of March. SouTHERN Crow, Corvus brachyrhynchos paulus Howell. Common permanent resident. At the present time there are no large winter crow roosts in this vicinity, those previously used having broken up about six to eight years ago. The last large roost was near Woodridge and was used by several thousand crows for many years. The building up of this suburban region was probably largely responsible for the roost’s abandonment. Coues and Prentiss mention a large roost on the Vir- ginia shore some distance above Chain Bridge. Later the birds shifted _ to Arlington Cemetery where at one time they occupied twelve to fifteen - acres. This roost was abandoned soon after 1900. Crows are early breeders, begin pairing soon after the first of March and well incubated eggs have been found as early as March 23 (1894) though the majority of records are for early April. FisH Crow, Corvus ossifragus Wilson. Permanent resident, fairly common in summer, rare in winter. This is the common crow about the city and frequently nests in the Mall and other parks and sometimes in trees along streets. April 20, 1926, they were observed carrying nesting material in the Smithsonian grounds and young were seen in the Agricultural grounds July 4, 1914. Fresh eggs found from April 5 (1890) to May 24 (1910), young out of the nest, May 31 (1914). EUROPEAN STARLING, Sturnus vulgaris vulgaris Linnaeus. Common permanent resident, very abundant in winter, especially in the city where they roost by thousands. Starlings first appeared in Washing- ton, following astorm, January 21, 1912, when two were collected near Ana- costia. Each winter following they occurred in increasingly large flocks but the first evidence of breeding was young of the year seen at Woodridge June 26, 1916 (F. Harper). The following spring found the species spreading into the adjoining country. In the earlier years starlings roosted in late summer and winter in trees in the Mall. Following a heavy snowstorm in late January, 1922, thousands were found roosting on various buildings in the business section of the city. These roosts have increased until now many of the buildings, especially along Pennsylvania Avenue between Ninth and Fourteenth Streets, are lined with starlings every night. They begin coming to these roosts in numbers in October and break up in late March. In January, 1928, nearly 4,000 were banded in the steeple of the First Presbyterian Church at John Marshall Place. 44 Proceedings of the Biological Society of Washington. Bosournk, Dolichonyzx oryzivorus (Linnaeus). Migrant, more common in fall than in spring; less abundant than formerly. Spring: April 26, 1896 (H. Oldys), to June 6, 1909 (H. W. Henshaw); average, May 2 to 22. Fall: July 23, 1904 (S. D. Judd), to October 21, 1894 (Wm. Palmer); average, August 18 to September 29. Birds seen in November are almost certainly cripples. CowsirpD, Molothrus ater ater (Boddaert). Tolerably common local summer resident, sometimes winters. Egg taken May 12 (1895). Average, March 19 to November 3. YELLOW-HEADED BLACKBIRD, Xanthocephalus xanthocephalus (Bonaparte). A western species which has once been taken, a female collected near the city on August 29, 1892, by E. M. Hasbrouck. There are three records for the vicinity of Baltimore, Maryland. RED-WINGED BLACKBIRD, Agelatus phoeniceus phoeniceus (Linnaeus). Abundant migrant and common summer resident in the marshes; a few usually winter. Nesting begins about the middle of May; slightly incu- bated eggs found May 19 (1889). Average, March 1 to November 19. MeEapow.ark, Sturnella magna magna (Linnaeus). Common permanent resident, less abundant in winter. Nesting begins in late April; young just hatched, May 18 (1891). OrcHARD ORIOLE, [cterus spurius (Linnaeus). Tolerably common summer resident. Nesting begins soon after the middle of May and young birds have been found June 20 (1888). April 25, 1908 (A. H. Howell), to September 14, 1919 (F. Harper); average, May 3 to August 27. BALTIMORE ORIOLE, Icterus galbula (Linnaeus). Common migrant and rare summer resident. Eggs May 27 (1887) and chattering young in nest June 16 (1914). April 24, 1912 (H. H. T. Jackson), to October 15, 1922 (J. Kittredge, Jr.); average, May 2 to September 1. A specimen that had recently died was picked up in Anacostia, January 5, 1925 (C. H. M. Barrett). Rusty BLacKBirD, Euphagus carolinus (Miiller). Common migrant, occasional in winter. September 16, 1885 (H. W. Henshaw), to May 14, 1926 (W. H. Ball); average, October 22 to April 18. Cooke—Birds of the Washington, D. C., Region. 45 PuRPLE GRACKLE, Quiscalus quiscula quiscula (Linnaeus). Abundant summer resident, a few usually winter. They nest commonly in the parks and larger yards of the city. Nesting begins early in April; eggs have been found April 17 (1887) and young out of the nest May 4 (1913). The breeding season is rather prolonged, but it is doubtful if, under normal conditions, more than a single brood is raised. Average, February 23 to November 16. BRONZED GRACKLE, Quiscalus quiscula aeneus Ridgway. Migrant, probably occurring every year, but seldom distinguished. All definite dates are in winter or spring and range from January 21, 1916 (Mrs. F. M. Bailey), to April 17, 1886 (spec. Nat. Mus.). The majority of the records are during February and March. EvENING GrosBEAK, Hesperiphona vespertina vespertina (W. Cooper). _ An accidental visitant from the northwest. This bird was added to the Washington list in 1922 when a flock of 5 to 6 was seen April 3-6, at Laurel, Md., by George Marshall. On April 21 of the same year a flock of about a dozen birds was found in the Zoological Park and on April 25 a specimen was taken by A. K. Fisher which is now in the National Museum. Birds were seen until May 12, and individuals were reported from Takoma Park and Cabin John Bridge, Md. ENnGLisH SPARROW, HovussE Sparrow, Passer domesticus domesticus (Linnaeus). Abundant permanent resident. This European species was introduced in Washington in 1871. Cages for them were hung in some of the parks of the city, notably in Franklin Square. They became very abundant about 1900. Since the automobile has largely replaced horses, English sparrows have considerably decreased in numbers, but they are still abundant. Four or five broods are sometimes raised in one season. A female has been seen carrying straws as early as February ie (1894), but the nesting season begins usually early in March. PuRPLE Fincu, Carpodacus purpureus purpureus (Gmelin). Fairly common winter visitant, abundant spring migrant; less common in fall. Sometimes very abundant in the city trees in early May. August 23, 1923 (J. Kittredge, Jr.), to May 29, 1860 (spec. Nat. Mus.); average, October 22 to April 18. AMERICAN CROSSBILL, Lozia curvirostra minor (Brehm). Irregular winter visitant, sometimes common. It has been noted from October 10 (1886, H. W. Henshaw) to June 5 (1895). A female taken May 23, 1884 (R. Ridgway), showed unmistakable evidence of having recently incubated. A young bird barely able to fly was taken with an adult, May 17, 1885 (H. M. Smith). These seem to be the only evidences of the breeding of this species in the vicinity. 46 Proceedings of the Biological Society of Washington. NEWFOUNDLAND CROSSBILL, Loxia curvirostra percna Bent. Accidental visitant, a specimen taken at Four Mile Run, Va., November 30, 1919, by A. Wetmore. WHITE-WINGED CrossBILL, Loxia leucoptera Gmelin. Irregular winter visitant. One, about 1864 (C. Drexler, in Nat. Mus.); specimens about 1874 (Henry Marshall); one, November, 1906 (J. H. Fleming); one taken at Oxon Hill, Md., August 11, 1907 (brought to Biological Survey); flock, October 23, 1918, at Takoma Park (R. W. Williams); tolerably common from December 10, 1916 (W. L. McAtee), to January 16, 1917 (D. C. Mabbott); flock of 15 in Woodridge, D. C., February 25, 1923 (EH. R. Kalmbach). REDPOLL, Acanthis linaria linaria (Linnaeus). Accidental winter visitant from the north. A flock seen and one taken, February 19, 1875, at Ft. Runyon (T. H. Bean, spec. in Nat. Mus.); seven, February 12, 1899, just before the great blizzard (Wm. Palmer); small flock in Rock Creek Park, March 9 (R. W. Moore) to March 12, 1914 (M. T. Cooke); six or eight February 22, 1925 (T. H. Kearney). AMERICAN GOLDFINCH, Astragalinus tristis tristis (Linnaeus). Common permanent resident, abundant in spring migration. This is one of the latest species to nest and does not begin until July. The earliest available date for eggs is July 12 (1885) and young have been found still in the nest September 10 (1890). Pine Siskin, Spinus pinus (Wilson). An irregular winter visitant, sometimes common, some winters almost totally absent. October 15, 1916 (F. Harper), to May 22, 1926 (R. V. Truitt); average, October 24 to May 14. Snow Buntine, Plectrophenax nivalis nivalis (Linnaeus). Accidental winter visitant from the north. Recorded February or — March, 1842 (National Institute); one near Soldiers’ Home, November, 1906 (Wm. Palmer); a large flock near Congress Heights, February 18, 1905 (2 specimens brought to Biological Survey); a flock near Cabin John Bridge February 22, 1905 (Cary and Piper); one December 19, 1917, on Eastern Branch (C. H. M. Barrett); one below Alexandria February 12, 1927 (W. H. Ball); two seen, one collected at Hains Point November 29, 1928 (Ball). Lapuanp Loneserur, Calcarius lapponicus lapponicus (Linnaeus). Accidental visitant, has been once recorded; six or more were seen and one collected at Bailey’s Cross Roads, Va., December 11, 1886, by H. W. Henshaw. Cooke—Birds of the Washington, D. C., Region. 47 VESPER SPARROW, Pooecetes gramineus gramineus (Gmelin). Common migrant and rare and local summer resident. The spring migration is of rather short duration. Eggs have been found from June 3 (1889) to July 6 (1888). Spring: Earliest, February 18, 1890 (Wm. Palmer); average, March 23 to April 15. . Fall: Latest, November 21, 1886 (A. K.

Two, and possibly three, broods are raised; eggs have been found from April 15 (1888) to July 16 (1916); young leaving the nest May 5 (1921) and young recently from the nest August 24 (1919). ROSE-BREASTED GROSBEAK, Hedymeles ludovicianus (Linnaeus). Tolerably common in migration, but its stay is rather brief and it frequently escapes detection. Spring: April 17, 1902 (H. W. Maynard), to June 3, 1917 (I. N. Gabrielson); average, May 3 to 17. Fall: August 29, 1926 (Wetmore and Lincoln), to October 16, 1920 (J. Kittredge, Jr.); average, September 4 to October 1.

In 1860 this was an abundant migrant and common summer resident, arriving about May 1. From 1860 to about 1875 it was still a regular visitant; about 1872, Mr. Robert Ridgway found it not uncommon on Columbia Heights, and he saw one near Aqueduct Bridge in 1874. About 1875 the species disappeared from the entire eastern portion of its range, and since then has been seen in this region in only two years; one near Soldiers’ Home, May 31, 1887 (H. W. Henshaw); one in Brookland, late May or early June, 1894 (R. Ridgway); one at the Washington Barracks (War College) in late June or early July, 1894 (W. Robinson). Cooke—Birds of the Washington, D.

For the last dozen years large roosts have been formed in the city; for a couple of years in trees opposite the Red Cross building, and since then in the vicinity of New Jersey Avenue and P Street. The local birds begin gathering soon after the young are on the wing, early in July, and are soon joined by migrants from the north, which continue to use the roost until September. At the height of the migration as many as 30,000 birds have been estimated to occupy the roost in a single night. Although the first of the swallows to arrive they apparently do not begin nesting until late in May. March 13, 1910 (1. R. Hitt), to October 1, 1928 (M. T. Donoho); average, April 2 to September 12.

March 24, 1928 (M. T. Donoho), to September 11, 1920 (H. C. Oberholser); average, April 9 to September 4. Cepar Waxwine, Bombycilla cedrorum Vieillot. Tolerably common permanent resident, but sometimes in spring very abundant in the shade trees of the city; not common in summer. This is one of the species that does not breed until late in June. NORTHERN SHRIKE, Lanius borealis Vieillot. Very rare, or accidental winter visitant. In over 80 years it has been recorded in only about a dozen winters. February 10, 1846 (spec. Nat.

MiGRANT SHRIKE, Lanius ludovicianus migrans W. Palmer. Uncommon permanent resident. The earlier collectors knew this bird only as a rather rare winter visitant. Coues and Prentiss did not include it in their first list. Very few were known to breed within our area until after the first decade of the present century. Since then it has increased until now it may be classed as uncommon and local as a breeding species, more common in winter. Nest with female on it found April 22 (1914) and young left nest at Bell Station, Md., May 20, 1910. Cooke—Birds of the Washington, D. C., Region. 53 RED-EYED ViREO, Vireosylva olivacea (Linnaeus).

Oldys), to October 18, 1890 (C. W. Richmond); average, April 17 to September 23. PROTHONOTARY WARBLER, Protonotaria citrea (Boddaert). This is the most recent addition to the list of breeding species, the first nest having been taken at Dyke, Va., June 9, 1928, by F. C. Lincoln. This is a notable case of a species which has increased in recent years. Previous to 1911, it had been recorded only four times; since then it has occurred nearly every year. It is confined almost entirely to the region between Dyke and Mt.Vernon, only two records being from other localities; Falls Church, Va. (Gabrielson), and Chevy Chase, Md. (Stimson). The increase is not merely apparent, for the area where it occurs has been under close observation in spring since about 1905. For several years only single birds were observed, but in 1928 at least 5 were present near Dyke. In 1915 a single bird was noted several times during June (R. W. Moore) and 2 on July 15, 1922. The first definite evidence of nesting was a bird seen gathering nesting material on May 30, 1928. The nest, eggs, and female were collected on June 9 and are now in the National Museum. The earliest date of arrival is April 22, 1922 (Katharine H. Stuart). WoORM-EATING WARBLER, Helmitheros vermivorus (Gmelin).

Cooke); May 18, 1909 (R. W. Shufeldt); May 20, 1922 (M. T. Cooke); May 4, 1926 (Ruppert and Ball). CHESTNUT-SIDED WARBLER, Dendroica pensylvanica (Linnaeus). _ Usually a common migrant, some years rather scarce. This is a bird of the second growth deciduous woods and is often found in the trees along streams outside the woods. Spring: April 19, 1902 (H. W. Maynard), to June 2, 1917 (L. D. Miner); average, May 1 to 21. Fall: August 10, 1894 (J. D. Figgins), to October 14, 1906 (A. K. Fisher); average, August 24 to September 28. BAY-BREASTED WARBLER, Dendroica castanea (Wilson). Tolerably common in migration. One of the last warblers to arrive in spring. Arlington Cemetery is an especially good place to look for this species. ~ Spring: May 2, 1896 (H. Oldys), to June 5, 1917 (I. N. Gabrielson); average, May 10 to 25. Fall: August 17, 1921 (B. H. Swales), to November 6, 1887 (H. W. Henshaw); average, September 7 to October 8. BLACKPOLL WARBLER, Dendroica striata (J. R. Forster). An abundant migrant. It is one of the late arrivals in spring and through the latter half of May its staccato song can be heard commonly about the city. Spring: April 21, 1916 (R. W. Moore), to June 16 in three different years; 1907 (R. W. Williams); 1915 (A. H. Howell), and 1926 (S. F. Blake); average, May 5 to June 1. Fall: August 17, 1912 (H. C.

Cooke); average, May 8 to 21. Fall: August 2, 1872 (E. Coues), to October 10, 1919 (Miss M. J. Pellew); average, August 27 to September 26. YELLOW-THROATED WARBLER, Dendroica dominica dominica (Linnaeus). Local summer resident. It is a tolerably common bird in the moist woodlands bordering the river from Dyke southward, but there are very few records of its occurrence farther up the river. It has been recorded in spring in Arlington Cemetery, the National Zoological Park, and on the Eastern Branch above Bennings. Coues and Prentiss called this species accidental and in 1883 knew of only two specimens. Eggs May 2 (1896) near Mt. Vernon and young on the wing July 12 (1896). March 30, 1927 (Katharine H. Stuart), to September 11, 1927 (H. G. Deignan); average, April 15 to September 4. BLACK-THROATED GREEN WARBLER, Dendroica virens (Gmelin). Common in migration, when it is found in mixed woodland and usually well up in the trees, but its characteristic song betrays its presence. Spring: April 18, 1920 (B. H. Swales), to June 10, 1917 (D. C. Mab- bott); average, April 29 to May 20. Fall: August 22, 1921 (J. Kittredge, Jr.), to October 21, 1888 (spec. Nat. Mus.); average, September 6 to October 7.

Probably occurs every year in migration, but not often distinguished from the commoner Yellow Palm. _ It has been noted in spring from April 18, 1904 (W. W. Cooke), to May 20, 1917 (W. L. McAtee), and in fall from September 18, 1887 (W. Palmer), to October 11, 1861 (P. L. Jouy). YELLOW PALM WARBLER, Dendroica palmarum hypochrysea Ridgway. Common in migration, usually found outside the woods. Along the canal is a good place to find this bird. Cooke—Birds of the Washington, D. C., Region. 59 Spring: March 28, 1926 (F. C. Lincoln), to May 13, 1923 (Lincoln); average, April 9 to 29. Fall: September 4, 1887 (H. W. Henshaw), to November 18, 1914 (J. H. Riley); average, September 19 to October 19. Prairie WARBLER, Dendroica discolor (Vieillot). Common summer resident in the scrub pines, where it would seldom be observed were its presence not betrayed by its characteristic song. Eggs found May 14 (1891) to July 1 (1890); young in the nest, June 14 (1896). April 12, 1883 (H. W. Henshaw), to October 3, 1910 (E. J. Brown); average, April 23 to September 16. OvENBIRD, Seiurus aurocaptllus (Linnaeus). Common summer resident. Eggs found May 12 (1896) to June 3 (1906); young in nest, May 24 (1896). April 10, 1904 (J. H. Riley), to November 13, 1887 (H. W. Henshaw); average, April 23 to October 3. NorRTHERN WATER-THRUSH, Seiurus noveboracensis noveboracensis (Gmelin). Common in migration, found in low wet ground, often seen along the bank of the river. Spring: April 16, 1921 (Miss M. J. Pellew), to June 2, 1907 (A. K. Fisher); average, April 27 to May 23. . Fall: July 28, 1889 (J. D. Figgins), to October 16, 1919 (M. J. Pellew); average, August 9 to September 25. | GRINNELL’S WATER-THRUSH, Seiurus noveboracensis notabilis Ridgway. A western race of the Northern Water-thrush which has been taken three times; May 11, 1879 (Wm. Palmer); May 5, 1885 (Palmer); August 5; 1886 (A. K. Fisher). Louisiana WATER-THRUSH, Seiurus motacilla (Vieillot). Common summer resident. It breeds along most of the wooded streams, where its wild, ringing song may often be heard though the bird can not be found. Seen nest building April 10 (1908), eggs May 8 (1921) to May 28 (1888); young on the wing May 24 (1896). March 27, 1921 (Miss M. J., Pellew), to October 4, 1920 (Pellew); average, April 4 to September 19. Kentucky WARBLER, Oporornis formosus (Wilson). Tolerably common summer resident. Its increase in recent years may be more apparent than real, and due to the greater accessibility of its haunts and the larger number of observers. Eggs have been found from May 22 (1915) to June 15 (1879); small young about the middle of June (1894) and young strong on the wing July 20 (1913). 60 Proceedings of the Biological Society of Washington. April 25, 1920 (W. N. Koelz), to September 5, 1920 (A. K. Fisher); average, May 2 to August 27. ConneEcTICUT WARBLER, Oporornis agilis (Wilson). This is one of the species whose spring and fall migration routes are different. Consequently it is only accidental in spring while in fall it is a tolerably common migrant. Spring: Four specimens in 1882; May 22 (D. W. Prentiss), May 24 (H. W. Henshaw), May 28 (Wm. Palmer), May 30 (E. W. Nelson); May 24, 1891 (Wm. Palmer); May 17, 1909 (W. H. Osgood), April 30, 1911 (H. H. T. Jackson). Fall: August 28, 1886 (A. K. Fisher), to October 24, 1889 (Wm. Palmer); average, September 21 to October 14. Movurnina WARBLER, Oporornis philadelphia (Wilson). Rare migrant. It is seldom found outside of the denser woods and in spring does not appear until so late that it is usually missed. Spring: May 4, 1928 (W. J. Whiting), to June 7, 1917 (F. Harper); average, May 15 to 28. Fall: August 17, 1894 (George Marshall), to October 1, 1894 (Wm. Palmer); average, August 19 to September 30. MaryYLAND YELLOW-THROAT, Geothlypis trichas trichas (Linnaeus). Abundant summer resident near water and in swampy places. Two broods are raised; fresh eggs have been found from May 1 (1887) to June 22 (1884). On June 14, 1914, at Four Mile Run, one nest was found from which the young had flown, another with eggs just hatching, and another with one egg. April 13, 1891 (Wm. Palmer), to November 2, 1919 (F. Harper); average, April 22 to October 6. Two accidental records in De- cember; one near Arlington, December 29, 1913 (Preble and McAtee); one in Meridian Hill Park, December 12, 1927 (M. T. Cooke). NorTHERN YELLOW-THROAT, Geothlypis trichas brachidactyla (Swainson). Common in migration but the records are not separable from those of the Maryland Yellow-throat.

April 14, 1927 (Miss H. P. Childs), to October 4, 1925 (A. Wetmore); average, April 30 to September 19. Cooke—Birds of the Washington, D. C., Region. 61 HoopED WARBLER, Wilsonia citruna (Boddaert). Common summer resident. This species seems to have increased in recent years but this may be partly due to its haunts having become better known and visited by more observers. Coues and Prentiss called it only a straggler. Young just out of the nest have been found June 8 (1902). April 13, 1919 (A. Wetmore), to October 1, 1899 (J. H. Riley); average, April 29 to September 14. WILson’s WARBLER, Wilsonia pusilla pusilla (Wilson). Uncommon in migration, and usually found in low, brushy growth near water. Spring: May 1, 1876 (H. W. Henshaw); May 1, 1908 (A. M. Stim- son), and May 1, 1914 (A. Wetmore), to May 31, 1891 (F. C. Kirkwood); average, May 8 to 24. Fall: August 22, 1910 (W. W. Cooke), to October 18, 1919 (Miss M. J. Pellew); average, August 26 to September 19. CANADIAN WARBLER, Wilsonia canadensis (Linnaeus). Common in migration, frequenting the bushes and lower branches. Spring: May 2, 1923 (J. Kittredge, Jr.), to June 2, 1917 (F. Harper); average, May 8 to 25. Fall: July 31, 1887 (A. K. Fisher), to October 23, 1921 (A. Wetmore); average, August 19 to September 16. AMERICAN ReEpstTart, Setophaga ruticilla (Linnaeus). Abundant migrant and common summer resident. Nesting begins about the first of May (April 27, 1926, a female was seen to bring the first straws to the nest site), and eggs have been found as late as June 25 (1910). Young just hatched were found June 12 (1895). April 15, 1877 (Wm. Palmer), to October 138, 1927 (W. H. Ball); average, April 22 to September 20. AMERICAN Pipit, Anthus rubescens (Tunstall). A rather rare and irregular migrant. It has been said to winter, but there is no record of its occurrence in January. | Spring: February 16, 1908 (W. W. Cooke), to May 14, 1910 (E. A. Preble); average, March 11 to April 24. Fall: October 1, 1916 (F. Harper), to December 23, 1916 (J. P. Young); average, October 11 to November 27. MockincGBIRD, Mimus polyglottos polyglottos (Linnaeus). Permanent resident, now common and well distributed. Coues and Prentiss, in both lists, called this a rare summer resident. In the last decade of the last century it was almost unknown; active collectors might not find one in the course of several years. By 1902 or 1903 a few pairs (probably not over a half dozen) were known, but outside their particular 62 Proceedings of the Biological Society of Washington. localities the species was never seen. About 1905 it began gradually to increase until it is now common. Dr. Wetmore reports that on August 22, 1925, he saw fifteen mocking- birds along a hedge in the space of a hundred yards near Cabin John, Md. The law prohibiting the taking of these birds for cage birds has undoubtedly been partly responsible for their increase. It is now common not only in the country but is also quite at home and frequently nests in the suburbs and even in the city. They begin nesting in late April and it is probable that more than one brood is raised, for young nae recently from the nest have been found early in August. CaTBIRD, Dumetella carolinensis (Linnaeus). Abundant summer resident. This is one of the species that comes into the suburbs and city parks. It occasionally remains into the winter. One was noted December 25-31, 1883 (H. W. Henshaw), and one recently killed January 13, 1889 (C. W. Richmond). One was noted near the Harvard Street entrance to the Zoological Park from December 13, 1924, to January 6, 1925 (W. H. Ball), and one appeared at a feeding table about a block from there about February 2, 1925 (Mrs. David White). Fresh eggs have been found from May 17 (1885) to July 12 (1885); young out of nest, June 14 (1914). March 14, 1918 (C. M. Shaw), to December 6, 1917 (B. H. Saralea): average, April 22 to October 25. One about February 1, 1898 (J. H. Gaut), and Febsuaes 21, 1915 (S. W. Mellott). Brown THRASHER, Toxostoma rufum (Linnaeus). Common summer resident. Eggs have been taken from early in May to the end of June; young on the wing May 30 (1888). March 4, 1867 (Spec. Nat. Mus.), to November 13, 1887 (C. W. Richmond); average, April 3 to September 26. In two years stray birds have appeared on February 22, in 1916 (Miner and Moore), and in 1925 (F. Bond). CaroLina WREN, Thryothorus ludovicianus ludovictanus (Latham). A permanent resident, usually near water, varying in abundance from year to year; at present fairly common. During a severe storm in Febru- ary, 1918, this species was nearly exterminated in this region and it was several years before it recovered. This is one of the most sedentary species, and year after year may be found near the same place. They have been found building as early as April 11 (1886), and fully fledged young were taken May 2 (1890). LEggs of the second brood were found in a Bank Swallow’s nest June 16, 1889 (C. W. Richmond). Bewicxk’s WREN, Thryomanes bewicki bewicki (Audubon). A southern species which straggles to our area, but though it has been found in summer, it has never been known to breed. Cooke—Birds of the Washington, D. C., Region. 63 Since 1882 it has been noted in spring in 14 years from March 26, 1897 (J. H. Gaut), to April 29, 1905 (A. H. Howell). One was seen at close range near Falls Church February 8, 1918 (J. H. Riley), and one recorded in “late May,” 1906 (Howell). On July 19, 1925, one appeared in the west court of the National Museum (H. H. T. Jackson). It has been recorded three times in fall; September 9, 1928 (Jackson); November 24, 1889 (J. D. Figgins); and December 22, 1890, on the Mall (C. W. Richmond). House Wren, Troglodytes aedon aedon Vieillot. Common summer resident. Two broods are usually raised and eggs have been taken from May 1 (1887) to July 7 (1885). March 26, 1910 (E. B. Gregg), to November 26, 1914 (F. M. Weston); average, April 18 to October 16. WINTER WREN, Nannus hiemalis hiemalis (Vieillot). A fairly common winter visitant whose elusiveness makes it seemingly a _ rarity. . September 25, 1925 (H. G. Deignan), to May 1, 1882 (spec. Nat. Mus.); average, October 5 to April 21. SHORT-BILLED Marsu WREN Cistothorus stellaris (Naumann). Apparently very rare in migration, but possibly not so rare as the few dates would indicate. Specimen May 9, 1890, near Rock Creek (E. M. Hasbrouck); specimen May 3, 1893, near the Tidal Basin (Hasbrouck); 2 seen May 10, 1927, ina meadow at Soldiers’ Home (W. H. Ball); one was collected (F. C. Lincoln) the next day and the other disappeared the day following. Lone-BiLLED Marsu Wren, Telmatodytes palustris palustris (Wilson). Abundant summer resident in the marshes along the Potomac River ahd Eastern Branch. There are two records in winter; one seen near Dyke, December 27, 1914—January 3, 1915 (W. W. Cooke), and one that wintered on Eastern Branch near Woodridge, 1919-1920 (F. Harper). Nesting begins the last of May for eggs advanced in incubation have been found June 1 (1885), and fresh eggs as late as June 26 (1887). April 17, 1920 (F. C. Lincoln), to November 16, 1926 (W. H. Ball); average, May 2 to October 9. Brown CrEEPER, Certhia familiaris americana Bonaparte. Fairly common winter visitant. One seen at Dranesville, Va., just outside our area, on June 2, 1912 (A. G. Whitney), was a delayed migrant. September 22, 1858 (HE. Coues), to May 9, 1925 (M. T. Donoho); average, October 6 to April 24. WHITE-BREASTED NuTHATCH, Sitta carolinensis carolinensis Latham. A tolerably common permanent resident. The nuthatch breeds almost entirely on the Piedmont Plateau and may be partially resident there. 64 Proceedings of the Biological Society of Washington. It is very rarely found on the Coastal Plain in summer but is tolerably common there in winter. They begin to nest about the middle of April; young have been found early in May. RED-BREASTED NUTHATCH, Sitia canadensis Linnaeus. A winter visitant, varying in abundance from common to rare in dif- ferent seasons. It is likewise quite erratic as to its times of arrival and de- parture. August 22, 1903 (W. L. McAtee), to May 20, 1917 (I. N. Gabrielson); average, September 24 to May 5. Turrep Titmouse, Baeolophus bicolor (Linnaeus). Abundant permanent resident everywhere except in the city. The breeding season begins early; young have been found as early as May 7 (1914). More than one brood is raised since young just out of the nest were found as late as August 3 (1919). BLACK-CAPPED CHICKADEE, Penthestes atricapillus atricapillus (Linnaeus). Very rare winter visitant. It has been frequently reported, but there are few records that can be considered authentic. Sight records are not reliable in the majority of cases. January 12, 1859 (spec. Nat. Mus.); December 10, 1859 (spec. taken by D. W. Prentiss now in Nat. Mus.); December 24, 1876, December 25, 1878, January 2, 1879 (specimens taken by Wm. Palmer); common March and April, 1885, 19 specimens taken March 15—April 19 (Wm. Palmer); October 19, 1896 (specimen by W. Palmer). CAROLINA CHICKADEE, Penthestes carolinensis carolinensis (Audubon). Common permanent resident. They begin nesting in April (2 with egg nearly ready to be laid taken April 11, 1888), eggs have been taken from April 27 (1879). Young out of nest May 19 (1926). GOLDEN-CROWNED KiINGcLET, Regulus satrapa satrapa Lichtenstein. A winter visitant, in some years abundant, in others rather scarce. - September 20, 1910 (E. J. Brown), to April 27, 1888 (E. M. Has- - brouck); average, October 7 to April 15. RUBY-CROWNED KINGLET, Regulus calendula calendula (Linnaeus). Common in migration, occasionally seen in winter. September 14, 1913 (W. W. Cooke), to May 17, 1917 (I. N. Gabriel- son); average, April 7 to May 4 and October 2 to November 7. BLUE-GRAY GNATCATCHER, Polioptila caerulea caerulea (Linnaeus). Common summer resident, mostly on the Coastal Plain. They begin nest-building about the third week in April, and young on the wing have been found May 24 (1896). March 6, 1916 (L. D. Miner), to September 13, 1919 (F. Harper); average, April 8 to August 28. Cooke—Birds of the Washington, D. C., Region. 65 A bird seen October 24, 1896 (W. Palmer), was a cripple, as was prob- ably the one taken November 23, 1890 (C. W. Richmond). There are two records of its occurrence on New Year’s Day, both of the birds apparently in good condition: January 1, 1917, at the Arlington Experiment Farm (M. T. Cooke) and January 1, 1924, near the Tidal Basin (S. F. Blake), Woop Turuvussu, Hylocichla mustelina (Gmelin). Common summer resident, more abundant than formerly. They now nest freely about lawns in the suburbs as well as in the woods. Eggs have been taken from May 1 (1895) to June 8 (1895); young on the wing about June 15. April 13, 1888 (E. M. Hasbrouck), to October 30, 1913 (A. H. Howell); average April 24 to October 1. Witson’s Turusu, Verery, Hylocichla fuscescens fuscescens (Stephens). Common in migration. The migrant thrushes slip through so quickly - and silently that they seem much rarer than they really are. Spring: April 9, 1922 (F. C. Lincoln), to June 2, 1907 (A. K. Fisher); average May 1 to 19. | Fall: August 18, 1889 (J. D. Figgins), to October 1, 1916 (L. D. Miner); average August 23 to September 13. ; Wittow Turvss, Hylocichla fuscescens salicicola Ridgway. A specimen of this western race of the Veery was taken in the Zoological Park September 2, 1920, by Ned Hollister. Another was reported seen near the same place May 7, 1922, by H. C. Oberholser. GRAY-CHEEKED TurRvsH, Hylocichla aliciae aliciae (Baird). Fairly common in migration. - Spring: May 6, 1928 (F. C. Lincoln), to June 3, 1917 (I. N. Gabriel- son); average, May 10 to 26. Fall: September 1, 1860 (spec. Nat. Mus.), to October 20, 1903 (A. K. Fisher); average, September 21 to October 7. BickNnELL’s TurvusH, Hylocichla aliciae bicknelli Ridgway. This race is tolerably common in migration, but since it can not be distinguished in the field from the Gray-cheeked Thrush, there are few definite records. Specimen records are as follows: 2 May 14, and 1 May 18, 1888 (R. Ridgway); May 17, 1892, and May 24, 1893 (E. A. Preble); May 27, 1903 (W. W. Cooke); October 3, 1885 (C. W. Richmond). OLIVE-BACKED Turusu, Hylocichla ustulata swainsoni (Tschudi). Common in migration. Spring: April 18, 1925 (M. T. Cooke), to June 2, 1917 (F. Harper); average, May 3 to 24. Fall: September 1, 1926 (A. Wetmore), to November 1, 1886 (A. K. Fisher); average, September 15 to October 9. 66 Proceedings of the Biological Society of Washington. Hermit Turvusu, Hylocichla guttata pallasi (Cabanis).. Common migrant and rare winter visitant. Spring: Latest, May 17, 1902 (W. W. Cooke); average, March 24 to May 1. Fall: Earliest, September 18, 1900 (R. W. Shufeldt): average, October 16 to November 20. NorTHERN Rosin, Planesticus migratorius migratorius (Linnaeus). Abundant in migration, a few in winter, the majority of the robins found in winter belonging to this race. Those found in the woods in early spring are nearly all migrant migratorius while those in the city are the breeding form, achrusterus. Their migration seems to be principally in March and October when robins are abundant in the woods. Specimens in the National Museum collection determined by J. H. Riley and A. Wetmore range in date from October 17, 1889, to April 4, 1884. There was a specimen in the collection of W. W. Cooke taken April 10, 1903. SouTHERN Rosin, Planesticus migratorius achrusterus (Batchelder). Abundant summer resident, but no specimens of this race have yet been recorded in winter. The earlier writers all refer to the robin as an ‘uncommon breeder, though common in migration. Since the killing of robins for market has been stopped, the species has greatly increased in abundance throughout the eastern United States. This is now one of the most abundant species about Washington from late February to early November, nesting freely about the city. Fresh eggs have been found from April 11 (1905) to July 3 (1887); young on the wing May 21 (1907). Specimens in the National Museum determined by J. H. Riley and A. Wetmore range in date from April 5, 1891, to October 29, 1859. BLUEBIRD, Sialia sialis sialis (Linnaeus). Permanent resident, local in winter, and only fairly common in summer. It is common during migration in March and October. The breeding season is a long one, for two and sometimes three broods are raised. Young in the nest have been found from April 28 (1921) to August 10 (1919). Bluebirds are much less common than formerly; several times, notably in the winters of 1895 and 1912, many have been killed by storms, and, at least in the latter case, they recovered their numbers very slowly. It is a question whether they have ever been as abundant since. HYPOTHETICAL LIST. AMERICAN GULL-BILLED TERN, Gelochelidon nilotica aranea (Wilson). Has been reported as ‘‘occasional in autumn’’ but no specimen has been found. One was reported seen off Hains Point, May 20, 1928 (W. H. Ball), and while there seems little reason to doubt the identification it seems best to consider this species as hypothetical until a specimen is obtained. | Cooke—Birds of the Washington, D. C., Region. 67 Buack SkimMErR, Rynchops nigra Linnaeus. Coues and Prentiss report having seen an individual of this species ‘‘on the Potomac, some distance below Washington,’ September 8, 1858. Another individual was reported seen briefly over the Anacostia River, April 14, 1928, by C. H. M. Barrett. In view of the uncertainty of these records it seems advisable to place the species on the hypothetical list until a specimen is obtained. WHITE-FRONTED GOOSE, Anser albifrons gambeli Hartlaub. The authority for including this species is a specimen in the National Museum bought in the Washington market in March, 1856, but there is no evidence that it was shot in the immediate vicinity. PRAIRIE CHICKEN, Tympanuchus americanus americanus (Reichenbach). A specimen taken March 17, 1885, was undoubtedly an introduced bird, for about that time birds taken in the west were liberated in Kent County, “Maryland. CHUCK-WILL’s-wiDow, Antrostomus carolinensis (Gmelin). The presence of this species in the list proves to be based on the record of a bird heard by Mr. Ridgway in 1895 and on descriptions of strange birds seen by other persons who were not acquainted with the species. Dr. Richmond had all the data available when he prepared his lists of 1898 and 1902 but thought best not to include it, and it seems best to transfer it to the hypothetical list until a specimen is obtained. ScISSOR-TAILED FiycaTcHEeR, Muscivora forficata (Gmelin). This is a south-western species of which there are two reports of birds seen by persons not familiar with the species. The nearest specimen record is from Aylett, Virginia, some distance beyond our territory. PinE GRosBEAK, Pinicola enucleator leucura (Miiller). A card in the Biological Survey files credits H. W. Henshaw with having taken a specimen of this northern species in January, 1888. Dr. Fisher, who collected with Mr. Henshaw at that time, says he has no knowledge of such a find, and since careful search of Mr. Henshaw’s original notes from which the cards were copied fails to show it, there was evidently some error in the copying. Since the only other record is of three reported seen November 26, 1903 (T. H. Levering), it seems best to consider this hypo- thetical until a specimen is secured. 68 Proceedings of the Biological Society of Washington. BIBLIOGRAPHY.

PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A 4 NEW BIRDS FROM PERU, BRAZIL, AND COSTA | RICA. BY JOHN T. ZIMMER.! Recent study of the collection of birds secured by the Cap- tain Marshall Field Peruvian Expedition of Field Museum of Natural History in 1922-23, has revealed the existence of a number of new subspecies which seem to be worthy of recog- nition. Most of the new forms here described were obtained by the expedition mentioned; the others appeared in material used for comparative study. Descriptions of other new forms from the same source have been published in Field Museum of Natural History Publication, Zoological series, vol. 12, no. 4, 1924; tom. cit. No. 8, 1925; and the present publication, vol. 40, 1927. The type specimens of the forms described below are in the collection of Field Museum of Natural History, as are all other specimens not otherwise accredited. Acknowledgments are due to Dr. Frank M. Chapman, American Museum of Natural History, New York; to Mr. W. E. C. Todd, Carnegie Museum, Pittsburgh; to Mr. O. Bangs, Museum of Compara- tive Zoology, Cambridge; and to Drs. C. W. Richmond and A. Wetmore, U. 8. National Museum, Washington. Compara- tive material generously loaned from these sources has been of great assistance in establishing the relationships of the various species and subspecies. I am indebted further to Dr. Crk: Hellmayr for notes on certain specimens in European museums and for freedom of access to manuscript notes of the late Count Berlepsch, which have aided in the study. Names of colors when capitalized indicate direct comparison with Ridgway’s “Color Standards and Color Nomenclature.”’ 1Published by permission of the Director, Field Museum of Natural History, Chicago. 2—Proc. Brox. Soc. Wasu., Vou. 42, 1929. (81) 82 Proceedings of the Biological Society of Washington. Xenops rutilus septentrionalis, subsp. nov. Type from Guayabo, Costa Rica. No. 35744, Field Museum of Natural History. Adult male collected January 29, 1908, by J. F. Ferry; original number 243. Diagnosis.—Similar to X. r. purusianus from Hyutanahan, Rio Puris, Brazil, but differs by having the pale streaks on the top of the head more rufescent and less buffy; back less strongly marked, with deeper ochraceous streaks; breast, flanks, and belly more narrowly streaked with pale shaft- lines; under tail-coverts averaging more rufescent in tone and less sharply streaked; tail with less black, having none on the outer webs of any of the rectrices except a minute shade at the extreme base, the black being con- fined almost entirely to the inner webs of the third and fourth and the basal half of the second outer feathers. From X. r. heterurus of Bogoté, Colombia, it is separable by the much lesser amount of black on the tail and by the narrower streaking below, together with somewhat smaller size. Wing (four males) 65-68 mm., average 67; tail 44-50, average 46.25; culmen from base 14—14.5, average 14.25; exposed culmen 10.5-138, average 12.5; tarsus 13-15, average 14. Habitat.—Central America, in Costa Rica (Juan Vifias and Guayabo) and Panamd4 (Boquete). Description of type.-—Top of head Mummy Brown with narrow shaft- streaks of deep Cinnamon-Buff, broadest on forehead; mantle Brussels Brown with pale ochraceous shaft-lines becoming obsolete on the lower border; mantle separated from the more dusky nape by an ill-defined and narrow collar which is slightly more rufescent than either the head or mantle; rump and upper tail-coverts light Sanford’s Brown grading in- sensibly into the color of the mantle. Lores white with a dusky area immediately in front of the eye; a broad superciliary stripe of slightly buffy white from the lores to the nape; a postocular stripe of Mummy Brown; auriculars dull white with dark brown edges; a broad, conspicuous subauricular stripe of silky white; sides of the neck like the back but the edges of the feathers grayer brown and the central stripes broader and whiter. Chin and throat dull white; sides of the lower throat, breast, sides, belly, and flanks Hair Brown x Olive Brown with narrow shaft- streaks of faintly buffy white, broadest on anterior portions; under tail- coverts Buffy Brown with whitish shaft-streaks less sharply defined than those on the remainder of the under parts. Under wing-coverts tawny Ochraceous Buff. Upper wing-coverts Snuff Brown with an ill-defined blackish or dusky area on the inner webs; primaries and secondaries largely black, narrowly margined externally with Sanford’s Brown x Amber Brown, and with a broad band of Ochraceous-Tawny across both webs of the median portion of the quills from the fourth outer primary to the penultimate inner secondary; the ochraceous color deeper and more tawny on the outer webs of the secondaries where it forms a bright patch visible on the closed wing; outer three primaries black except for the pale outer margin; inner secondary with a paler and more orange-tinted sub- basal area continuous with the band on the other quills but not so sharply Zimmer—New Birds from Perz%, Brazil, and Costa Rica. 83 defined; blackish distal patch on this quill reduced to an ill-defined dusky area; beginning with the sixth outer primary, the tips of the primaries and secondaries are Amber Brown x Sanford’s Brown, forming a narrow terminal margin on the primaries and a wider band on the secondaries; tertials entirely Amber Brown x Sanford’s Brown. Rectrices light Auburn; outermost rectrix entirely of this color; second with the basal third of the inner web, adjacent to the shaft, dusky; third with a broad black stripe on the inner web from the base to near the tip, not reaching the inner margin; fourth similar to the third but black region a little broader and longer, leaving a narrower rufous inner margin and tip; fifth and inner- most rectrices entirely light Auburn. There is no black on the outer webs of any rectrix except for a dusky shading at the very base. Wing 66 mm.; tail 45; culmen from base 14.5; exposed culmen 11; tarsus 15. A specimen from Juan Vifias, Costa Rica, has a small dusky spot on the inner web of the fifth rectrix near the tip. One specimen from Boquete, Panam4, has the blackish area on the third rectrix more or less broken about a third of the way from the tip. All four examples examined agree in the absence of black on the outer webs of the remiges. Peruvian specimens of purusianus are very close to this Central American form and agree with it in the disposition of the black markings on the tail, thereby differing from the average of topotypical purusianus. However, one male from Hyutanahdn has very little more black on the tail than have the Peruvian specimens, and as the latter agree with purusianus in other respects, according to the series at hand, it seems best to consider them as purusianus, at least for the present. On the other hand, the Central American birds, while showing affinity to purusianus through the Peruvian examples, are cut off from the range of that form by heterurus, which appears to occupy all three chains of the Andes in Colombia. Although purusianus was originally described as having a tail-pattern like that of heterurus, the material at hand tends to show that the black areas are rather more extensive in heterurus, occupy- ing the larger part of the outer webs of the fifth as well as the fourth rec- trices; in some specimens of purusianus there may be a certain amount of black on the basal portion of those webs but it does not extend so far toward the tip, and in other examples it is but little more extensive than in septentrionalis.

Pipra coronata circumpicta, subsp. nov. Type from Munichis, Yurimaguas, Peri. No. 50897, Field Museum of Natural History. Adult male collected September 1, 1912, by M. P. Anderson; original number 29. Diagnosis.—Closely allied to P. c. exquisita from central-eastern Pert but male slightly more obscure on the upper back, duller green on the breast, and duller yellow in a more restricted area on the belly; top of the head slightly darker blue, completely encircled by a border of much deeper blue which includes the forehead, upper part of the lores, supercilium, postocular region above the auriculars, and hind neck, which are clear green in exquisita; wing-quills browner, less blackish, with paler inner margins. , Habitat.—Northern Pert south of the Marafion River; Yurimaguas and Chyavetas. Description of type.—Back bright Grass Green, brighter on the rump, somewhat darker anteriorly; hind neck Cossack Green; auriculars and lower part of the lores Dull Blackish Green. Top of the head Pale Ceru- lean Blue (the feathers sooty black at their bases), completely encircled by a border of light Methyl Blue which involves the forehead, upper part of the lores, supercilium, postocular region above the auriculars, and the hind neck. Chin and throat Danube Green, passing into Bice Green on the breast and sides, Light Bice Green on the flanks, and Barium Yellow on the mid-belly and under tail-coverts. Wings and tail fuscous with the outer webs of the quills and upper coverts like the rump; inner margins of the wing-quills Pale Smoke Gray; under wing-coverts Marguerite Yellow. Mazxilla blackish; mandible soiled white; feet dull brown. Wing 57 mm.; tail 25; culmen from base 10; exposed culmen 7.5; tarsus 13.5. Although I have only a single specimen of this well-marked form, I do not hesitate to describe it since its characteristics have already been noted in other material from northern Peri. A specimen from Chyavetas was recorded as Pipra cyaneocapilla by Sclater and Salvin (Proc. Zool. Soe. London, 1867, p. 751) and by Taczanowski (Orn. Pérou, 2, p. 344, 1884). This same example and another from the Rio Huallaga were recorded as young males of cyaneocapilla by Sclater (Cat. Birds Brit. Mus., 14, p. 300, 1888). Hellmayr (Ibis, 1906, p. 36) found that these two specimens were fully adult though differing somewhat from typical exquisita, to which they were most closely related, and possibly belonging to a separable form. The reappearance of the same peculiarities in the Moyobamba specimen indicates the apparent stability of the characters in birds from that region. I place this new race in the species coronata at the suggestion of Dr. Hellmayr, who has worked out the relationship of coronata and exquisita in his forthcoming treatment of the family Pipridae. 1Specimens in Museum of Comparative Zoology, Cambridge.

Pipra pipra microlopha, subsp. nov. Type from Puerto Bermiidez, Rio Pichis, Pert; altitude 1100 feet. No. 65801, Field Museum of Natural History. Adult male collected March 18, 1923, by J. T. Zimmer; original number 3521. Diagnosis Somewhat intermediate between P. p. comata and P. p. coracina in the degree of gloss on the black plumage, but differing from both the others by having a shorter, more rounded crest; the bases of the feathers of the forehead, and sometimes of the whole crown, white, quite different from coracina though sometimes equaled by comata in this respect. Habitat.—Northeastern Peri and western Brazil south of the Amazon River; from the Ucayali eastward to SAo Paulo de Olivenga and probably _ as far as the Jurud4; tropical zone. Description of type-—General color bluish black, slightly more silky than in coracina but not as glossy as in pipra and comata. Whole top of the head, including nuchal crest, white, but the crest is rather short, tapering posteriorly to form an oval point in the middle of the hind neck instead of being produced into a flattened, broadly rounded collar lying over the upper part of the mantle as in the other races. The feathers of the fore- _ head and crown, back to the posterior border of the eyes, are entirely white; those of the rest of the cap are narrowly pale gray at the base. Wings and tail sooty black with the exposed outer edges and tips bluish black like the back. Wing 65 mm.; tail 28; culmen from base 11; exposed cul- men 9; tarsus 14; length of cap 27. Young males are, above, dark Kronberg’s Green, much darker than the dark Yellowish Oil Green of comata, with the whole top of the head dark gray, more or less washed with green. Below, Mineral Gray, somewhat washed with Kronberg’s Green on the breast and flanks and slightly tinged with green on the throat. Feathers of the crown with a trace of black on each side of the shaft at the base; some new white feathers which have appeared on the head of one of the specimens are white to the base as in the adult. One immature male, possibly younger than the others, has rather more green on the breast and a wash of the same color on the top of the head, while the mandible is pale yellow except at the extreme tip, not blackish as in the other immature examples and the adults. A female is similar to the young males but has the back a little lighter in color, about Kronberg’s Green; top of the head lighter gray, washed with green; throat whitish, washed with pale Lime Green; breast dark Tea Green; middle of belly white, tinged with Sea-foam Yellow in the anal region, less strongly on the under tail-coverts; flanks Deep Grape Green. Wing 63 mm. ; tail 26.5; culmen from base 12; exposed culmen 9; tarsus 14. - Among the adult males of this form there seems to be little or no varia- tion in the degree of gloss on the black feathers. The white cap is always short and oval at the tip, although the exact length is slightly variable. 86 Proceedings of the Biological Society of Washington. The feathers of the forehead are white to the base in all the specimens; those of the crown are also white in the type specimen. In one male from Sado Paulo de Olivenga, Brazil, the feathers of the crown at base are narrowly very pale gray, and those of the occiput are somewhat darker. One specimen from Orosa, Pert (nearly opposite the mouth of the Napo River) is a little darker in this respect, and two others from the same locality are even more marked, but none of the series is as heavily marked as typical coracina, which has the basal portion of the cap, sometimes including most of the forehead, much deeper and more broadly black. The type of microlopha apparently resembles the type of comata (as the latter was originally described) in having the crown feathers white to the base, but whereas comata was described on account of its unusually long crest, microlopha is notable for its very short crest. The extent of the dusky bases on the head is not constant, even in comata; two males from Uchco have the glossy plumage and long crest of comata, but the feathers of the crown are distinctly blackish at the base, possibly in an approach toward coracina which occurs not far distant, at Pomardé. On the other hand, a Yurimaguas male has the crown and occiput pale gray at base. This specimen seems to be abnormal. It is exceptionally small (wing 60 mm.; tail 25) and exhibits traces of albinism in various parts of its plumage, but its crest is proportionately long and broad at the tip, and its plumage is as glossy as in typical comata. A male from the mouth of the Curaray River, eastern Ecuador, seems to be intermediate between pipra and microlopha, having a moderately short crest with considerable white at the base of the crown feathers combined with a heavily glossed plumage which is somewhat lighter in tone than that of most examples of pzpra. Ihering (Rev. Mus. Paulista, 6, p. 485, 1904=May, 1905) records leucocilla (=pipra) from the Jurud region. This record certainly refers to the present new form since there is no allied form south of the Amazon except far to the eastward, on the Tocantins, where bahiae occurs. The measurements of five adult males of microlopha are as follows: wing 65-69 mm., average 67.2; tail 27-29, average 28.4; culmen from base 11-12, average 11.5; exposed culmen 8.5-9.5, average 9; tarsus 14; length of white cap 25—27.5, average 26.3. The use of the specific name pipra instead of leucocilla is, I believe, necessary. In 1758, Linnaeus described ‘‘Parus Pipra,” which he based on Seba’s account of the ‘‘Cacotototl”’ (Thes., 2, p. 102, pl. 96, fig. 5). Seba’s description and figure unmistakably represent a white-crowned manakin with a glossy black body, and as Seba is the only earlier authority quoted by Linnaeus in this connection, his species is entitled to the name pipra. Unfortunately, Linnaeus, after citing Seba and quoting an abbreviated diagnosis from his work, appended a more complete description of a totally different species (a flycatcher), which disagrees not only with Seba’s ac- count but also with a short diagnosis of his own which he quoted from his then unpublished ‘‘Museum Adolphi Friderici.”” In the latter work, published six years later, he erected the genus Pipra, applied a new name, leucocilla, to his own earlier diagnosis of P. pipra (which he elaborated but did not otherwise alter), and repeated his more lengthy description ; Zimmer—New Birds from Periz, Brazil, and Costa Rica. 87 of the flycatcher under the name leucocephala (= Arundinicola leucocephala) ; but he again confused matters by referring Seba’s account to leucocephala in spite of the obvious disagreement. No mention was made of the name pipra in either connection. Two years later, in the twelfth edition of the Systema Naturae, the names leucocilla and leucocephala were again used for the two distinct species, and here the original Parus Pipra was defi- nitely identified as leucocilla, although it was erroneously placed in syn- onymy in spite of its six years of priority. By this association, Linnaeus, as first reviser, succeeded in separating the integral parts of the composite Parus Pipra and in allocating the original name to one of the parts. Berlepsch and Hartert (Novit. Zool., 9, p. 53, footn., 1902) were unjustified in rejecting the name pipra, and Ridgway (Bull. U.S. Nat. Mus., 50, pt. 4, p. 744, 1907) used the name correctly. Linnaeus’s original reference gives the type locality of pipra as ‘‘in Indiis,”’ which is not sufficiently definite for modern zoology. It is ante- dated by Seba’s ‘‘montagnes de Tetzcocanara”’ which that author, in another connection, places ‘‘au Bresil’’; but there is considerable doubt attached to this name. In the first place, both Tetzcocanara and Caco- tototl suggest Mexican, rather than Brazilian, origin. Seba’s reference to Hernandez in connection with another species also said to be from Tetzco- canara gives a clue to the probable explanation. Hernandez (Rev. Med. Nov. Hisp. Thes., Hist. Animal., lib. unic., p. 52, cap. CXCVII) gives the description of a bird which he calls ‘‘Cacatototl” from the ‘‘planis Tetz- coquensibus”’ in Mexico. There is not much doubt that Seba took name and locality from this account, although his own description (which does not agree at all with that of Hernandez) was drawn up from specimens which he received from a Jacques Guillot of Amsterdam who, in turn, probably secured them from Surinam. In any case Seba’s species does not occur in Mexico and Tetzcocanara or Tezcuco can not well be the type locality of the bird which he described and figured. Linnaeus’s citation of Brazil and Surinam, in the twelfth edition of the Systema Naturae, in connection with leucocilla, is probably correct, and Surinam, as the most definite locality given, should be designated as type locality for Parus Pipra. The Cacatototl of Hernandez has yet to be identified. Specimens examined: P. p. pipra—Surinam: Rijsdijkweg 1 o.

Phrygilus unicolor inca, subsp. nov. Type from the mountains near Hudnuco, Pert; altitude 12200 feet. No. 60073, Field Museum of Natural History. Adult male collected June 19, 1922, by J. T. Zimmer; original number 2404. Diagnosis.—Similar to P. u. unicolor of northern Chile, but smaller and decidedly darker above and below; more sooty, less ashy. Habitat Highlands of Pert. | Description of type-—Above, Slate Gray. Below, Dark Gull Gray, slightly paler and duller near the crissum. Wings and tail black; upper wing-coverts bordered with the color of the back; alula with the outer border a little paler, about the color of the breast; second to fifth outer primaries with their outer margins distinctly white except toward the tips of the quills; outermost primary with the outer margin slightly grayer than the rest of the outer web, faintly tinged with brown; inner primaries, secondaries and tertials with outer margins the color of the back, becoming paler and more whitish near the tips. Rectrices with outer margins the color of the breast, inclining toward whitish. Under wing-coverts gray like the breast. Iris brown; bill brownish black; feet dull brown. Wing 85 mm.; tail 57.5; culmen from base 13.5; exposed culmen 11; tarsus 23. Females are like the males and sometimes almost indistinguishable, but are usually paler below, between Gull Gray and Deep Gull Gray, with indistinct dusky shaft-lines; belly and crissum approaching Pale Gull Gray. Above, the feathers of the head and back have broad dusky shaft- lines, rather ill-defined, and sometimes have a brownish tinge on the mar- gins, but the color is still definitely gray and quite distinct from the brown of the young birds. Both sexes in juvenal plumage are closely streaked throughout. Above, the blackish brown shaft-stripes are margined with buffy brown on the crown, with Hair Brown on the upper back, and with Sepia on the middle back. Below, the feathers are dark Clove Brown in their centers, edged with whitish Pale Olive Buff. A characteristic feature is an area of Dark Olive Buff on the sides of the face, including the lores, auriculars, malar region and eyelids. The upper wing-coverts are brownish black margined with buffy brown. Wings and tail are margined externally with grayish buffy brown. In this plumage, inca is easily separated from unicolor by the much broader and darker streaks on the upper and under parts, by the darker edges of the dorsal feathers, and by the olivaceous sides of the face. Males in first annual plumage are similar to the juvenals in being streaked above and below, but the streaks are much less pronounced (especially below), the whole tone of coloration is much grayer and less buffy, and the sides of the face have lost the curious olive color. It is not my intention to enter here into a detailed discussion of the various plumages of this and related species as I hope to do in a later paper. Suffice it to say that there is evidence at hand which indicates that both sexes are very much alike in wnicolor, tucumanus, and inca, but noticeably different in some of the more northern races. eee ee ee ———S~ SO oe = = eo ee oe ee See ee ea ee. a ee a ae, ee ‘ 7 ; if + Zimmer—New Birds from Periz, Brazil, and Costa Rica. 89 The present form probably is more closely approached by tucumanus than by typical wnicolor, to which I have compared it in the diagnosis, since tucumanus also is smaller and darker than wnicolor though it does not go so far in this direction as typical inca. Specimens from Tucumdén are farther removed from both unicolor and inca than are Bolivian examples, which show an approach to unicolor in size and to inca in color but remain closest to tucumanus. Three adult males of inca measure as follows: wing 81-89.5 mm., aver- age 85; tail 56-60, average 57.8. Six adults of tucumanus (marked as males) from Tucumén measure: wing 85.5-89 mm., average 87.8; tail 61-65, average 62.5. Six males of tucumanus from Bolivia measure: wing 91-96 mm., average 92.6; tail 61.5-69, average 63.75. Nine males of unicolor from Chile measure: wing 91-98 mm., average 93.4; tail 62-68, average 64.5. Females of all three forms are a little smaller than the males in average measurements. North of the range of inca occurs the Ecuadorean form, grandis, which is again larger than paler than inca, being more like topotypical tucumanus ~~ in color and Bolivian tucwmanus in size, although it has a longer bill than either. The Peruvian form described herewith exists as a small, dark race replaced by larger, paler forms both to the north and south. The general failure to recognize this Peruvian race heretofore may be attributed to a protracted misidentification of unicolor. The species, unicolor, was described by d’Orbigny and Lafresnaye from the Cordillera of Tacora, Pert, and the Pampa de Oruro, Bolivia, and Tacora usually has been considered, as it may be more formally designated, as the type locality. Tacora belonged to Pert at the time the species was described, and most authors, misled by this fact, have referred all Peruvian speci- mens of this group to the Tacora form without having examined topotypes. Tacora now belongs to Chile, being situated not far from Choquelimpie, and specimens from Choquelimpie agree with others from other parts of Chile but differ from Peruvian examples. Thus, while Peruvian speci- mens of this group have long been known and Chilean examples have been comparatively rare, the latter appear to be entitled to the name unicolor, leaving the Peruvian race in need of formal description. In 1844, Tschudi (Arch. Naturg., 10, (1), p. 290, no. 162, May, 1844) described Phrygilus rusticus from Pert. This name has been placed in the synonymy of unicolor by various authors and, if it referred to the present species, it would be valid for the race I have described here as inca. Dr. Hellmayr has kindly examined Tschudi’s type in the Berlin Museum and pronounces it a molting, immature specimen of the bird long known as Spodiornis jardinii Sclater, over which latter name rusticus thus has priority. Tschudi’s description reads as though the author had had several specimens before him of different sexes and ages. Ten years after Tschudi’s description appeared there was but a single specimen of the species in the Berlin Museum (cf. Lichtenstein, Nom. Av. Mus. Berol., p. 43, 1854) and it is evident that Tschudi composed his description of the various plumages of his species from this single molting example. 90 Proceedings of the Biological Society of Washington. In any case, Phrygilus rusticus Tschudi does not affect the nomenclature of P. u. inca.

Chlorophanes spiza axillaris, subsp. nov. Type from Bahia, Brazil. No. 9701, Field Museum of Natural History. Adult male; no date; ex collection C. B. Cory, ex collection Lawrence. Diagnosis.—Similar to C. s. spiza from British Guiana, Trinidad, and Venezuela, but general color of males more greenish, less bluish, especially on the belly; hind neck without the yellowish tone which is usually pro- nounced in spiza; under wing-coverts and thighs decidedly paler, light gray instead of sooty black. Habitat.—Southeastern border of Brazil from Pernambuco to Santa Catharina. Description of type-—Whole top and sides of the head occupied by a black hood which extends from the base of the mandible along the lower border of the malar region to the auricular orifice, thence upward and a little forward to the postocular region where the line curves backward around the rear of the occiput. Held away from the light (toward the light all greenish colors are bluer) the hind neck appears Chrysoprase Green; back light Viridian Green; point of the chin black; remainder of under parts Cobalt Green x Vivid Green. Wings and tail black with the upper wing-coverts and outer margins of the remiges and rectrices similar to the back but a little duller; tertials and middle rectrices largely of the same color. Under wing-coverts, axillaries, and thighs Light Mouse Gray with moderately pronounced pale greenish tips, heaviest on the outer margin of the wing. Maxilla black with an angular yellow area at the base of the commissure below the nostril; in lateral view this reaches forward about to the middle of the commissure; in dorsal aspect it appears to end about at the anterior end of the nostril. Mandible entirely yellow; feet olivaceous. Wing 68.5 mm.; tail 46; culmen from base 18.5; ex- posed culmen 15; tarsus 18.5; length of black cap in the middle 22.

Wing 64.5 mm.; tail 45; culmen from base 18.5; exposed culmen 14.75; tarsus 16. In addition to the material listed below, I have notes which Dr. Hell- mayr has kindly made on an adult male from Blumenau, Santa Catharina, and two adult males from Brago do Sul, Victoria, in the Munich Museum, in comparison with sixteen males of typical spiza from Caparo, Trinidad. These notes confirm the characters which I have given for the southeast Brazilian race. They also indicate the existence of a longer black cap in axillaris than in spiza, but two males of spiza from Trinidad, in the col- lection of Field Museum of Natural History, have the cap longer than in the type of avillaris, showing the variability of this feature. The type of Turdus micans Hahn, in the Munich Museum, proves to be typical spiza, and two males from Paré show no trace of approach toward avillaris, being also typical spiza. The western limits of the range of this new form are uncertain. Ihering (Cat. Faun. Braz., 1, p. 344, 1907) records the species from Matto Grosso, but I suspect that the variety occurring there will be found to be caerules- cens and not azillaris; I have no material to determine the point.

THE BUTTERFLIES OF THE DISTRICT OF COLUMBIA.! BY AUSTIN H. CLARK. For some years the author has been gathering information _regarding the butterflies of the District of Columbia and vicinity with a view to publishing a detailed account of the local species, with special emphasis on their seasons, the forms in which they occur in this region, their local distribution, and their habits. It has seemed advisable to publish a preliminary list of the forms known to occur in this area in order to stimulate interest in the assembling of much needed information, particularly in regard to the earliest appearance of the various species, and the time of appearance of summer and autumn broods, concerning. which we have at present no definite information. The following list is based upon the collection of the late Mr. Henry F. Schénborn (H. F. §.), now in the National Museum, the collection of Mr. Ernest Shoemaker, of Brooklyn, N. Y. (E. 8.), and the collection of the author and his two sons, Austin B. J. Clark and Hugh U. Clark (C.). The local occurrence of the species is approximately indicated by the numbers immediately following the names. These numbers refer to the following habitats. —_ . Generally distributed in open country. . Generally distributed in woods. . Open woods and fields near woods. . Moist grassy regions. . Low ground along the river. . Open woods and bushy fields. _ Borders of fields and adjacent open woods. . Farm yards, roadsides and waste land. . Boggy areas along the Eastern Branch and in the vicinity of Beltsville. iS) Oconto or Ww 1Published with the permission of the Secretary of the Smithsonian Institution. 5—Proc. Brox. Soc.

Moist fields near willows, and hillsides with small poplars. 17. Along streams lined with alder or beech. The nomenclature herein used is that of the list recently published by William Barnes and Foster H. Benjamin, except that the American forms of Lycena phleas and of Lycenopsis argiolus are given as subspecies, and the black and white swallowtail is given as Papilio protesilaus instead of Papilio marcellus. Linné’s description of Papilio protesilaus reads: ‘Protesilaus. 29. P. E. alis caudatis subconcoloribus albidis: fasciis fuscis: unica subtus sanguinea, angulo ani rubro. Habitat in America septentrionali.” Linné added “Simillimus Podalirio Europe australis & Africe; an satis di- versus?’' 'The description can refer only to our zebra swallowtail, since there is no other form in North America to which it is applicable. Certainly it was never intended to cover the silky white species from Surinam to which it is usually applied, as Linné would never have called that form very similar to podalirius, nor would he have had any doubt about its distinctness from that species. The form of Junonia cena designated as ‘“‘wet’’ is the large dark form with the under side of the hind wings entirely deep pink. The “wet”’ form of Cynthia atalanta is the large blackish form with the orange band on the forewings narrow, often interrupted, and very deep in color.

The races characterized in the following paragraphs have been identified in the collections of the United States National Museum during studies of the extensive collections from Haiti and the Dominican Republic in that institution. Types of both species were collected by Dr. W. L. Abbott. In connection with this paper I am indebted to Dr. Witmer Stone of the Academy of Natural Sciences in Philadelphia for the privilege of examining a honey-creeper from Tortue Island collected by Mr. James Bond. Dulus dominicus oviedo, subsp. nov. Characters.—Similar to Dulus dominicus dominicus (Linnaeus)? but erayer brown, less olive above; rump and upper tail-coverts less extensively washed with greenish; averaging somewhat larger, with heavier bill. Description.—Type, U. S. Nat. Mus. Cat. No. 278751, male, in some- what worn plumage, collected at Pikmi, Gonave Island, Haiti, July 5, 1920, by Dr. W. L. Abbott. Back and scapulars between olive brown and buffy brown; hind-neck grayish olive, with obscure shaft streaks similar in color to the back; crown dull clove brown, the feathers margined faintly with grayish olive; auricular region dull blackish; rump and upper tail- eoverts citrine drab; rectrices blackish brown, margined basally with grape green; primaries and secondaries blackish brown, margined externally, es- pecially on the secondaries, with grape green; wing-coverts fuscous, mar- gined very faintly with whitish; under surface of body dull white, with a very faint cast of yellowish buff on abdomen and flanks, streaked broadly and sharply with clove brown, the streaks being broadest on breast and sides, and becoming obsolete on abdomen; under wing-coverts ivory yellow lined with clove brown; edge of wing whitish streaked with clove 1Published by permission of the Secretary of the Smithsonian Institution. 2Tanagra dominicus Linnaeus, Syst.

Upper mandible buffy brown, lower deep olive-buff; tarsus slate color; toes blackish slate (from dried skin). Measurements (in millimeters).—Four males, wing 90.4—92.2 (91.1), tail 72.3-80.7 (75.5), culmen from base 15.6-16.8 (16.2), tarsus 21.0—23.1 (22.3). Three females, wing 88.3—94.1 (90.9), tail 72.0—74.8 (73.0), culmen from base, 16.2-17.3 (16.9), tarsus 22.1-24.1 (22.9). Type, male, wing 91.2, tail 75.3, culmen from base 16.1, tarsus 22.6. Range.—Gonave Island, western Haiti. Remarks.—This form is described from seven skins secured July 5, 1920, at Pikmi, a village on the southeastern shore of Gonave Island. The series is quite uniform in difference from an extensive set of specimens from various parts of the main island. For comparison the following measurement of birds from Hispaniola proper (Haiti and the Dominican Republic) are offered: Males, 17 specimens, wing 82.3-89.8 (86.3), tail 65.6-77.0 (69.8), culmen from base 13.5-16.5 (15.1), tarsus 20.3-24.4 (22.3). Females, 15 specimens, wing 83.4—90.0 (86.8), tail 63.5—77.4 (68.3), cul- men from base 13.7-16.0 (15.0), tarsus 20.2—23.5 (22.2). It will be observed that the bird of Gonave Island averages appreciably larger in all measurements except the tarsus. Though occasional indi- viduals from the main island may be as large as Gonave specimens this is not usual. This race is named in honor of Capit4én Gonzalo Fernandez de Oviedo y Valdés, first among the early historians of the New World, who in his Historia General y Natural de las Indias, begun in 1535, gave to the world many observations on natural history, particularly from Hispaniola, where he resided for years. His account of the Paxaro comunero as he termed the palm-chat is highly entertaining. Coereba bananivora nectarea, subsp. nov. Characters.—Similar to Coereba bananivora bananivora (Gmelin)! but throat and foreneck decidedly darker gray. Description.—Type, U. S. Nat. Mus. Cat. No. 250608, male in fresh plumage, collected on Tortue Island, Haiti, February 1, 1917, by Dr. W. L. Abbott. Above sooty black with a very faint tinge of olive; super- ciliary line white, extended back to sides of nape; rump lemon yellow; a white spot on outer webs of sixth to eighth primaries, and a narrow white edging on outer webs of sixth to ninth primaries; throat and foreneck dark mouse gray; breast and upper abdomen lemon chrome; lower abdomen and under tail coverts dull white; sides and flanks vetiver green; edge of wing lemon yellow; under wing coverts white.

On page 375 of the 13th edition of the Systema Naturae, Gmelin described Corvus mexicanus in the following words: “C. totus ex caeruleo ater. Habitat innova Hispania, ad oppida, perpetim sonorus, monedulae magnitudine. Rostrum pedes et ungues nigri.””’ The references on which the bird was based are Pica mexicana major Briss. av. 2, p. 48, no. 4.; Hoitzanatl Raj., av. p. 162; Cirard, Pernetty, It. Mal. 1, p. 185; Hocisana, Buff. Hist. Nat. Ois. 3, p. 103; Mexican Crow, Lath. Syn. 1, pt. 1, p. 396, no. 34. These references are given in the order used by Gmelin, but for convenience I shall take them up chronologically beginning with Ray (Joannis Raii, Syn. Meth. Av. & Pisce. London, 1713). This author cites (p. 162) Hoitzanatl of Fernandez which is a lapsus for Hocitzanatl since the description agrees practically verbatim with Fernandez ‘Hocitzanatl.’”’? Brisson in 1760 gives as the basis for his Grande Pie de Mexique the Hocitzanatl of both Fernandez and Ray; Buffon, 1774, cites as ‘‘synonyms”’ of his “‘L. Hocisana” the Hocitzanatl of Fernandez and Ray together with the Grande Pie de Mexique of Brisson, while Latham in 1781 in characterizing his ‘‘ Mexican Crow”’ bases it on Ray, Brisson and Buffon, adding the “‘Criard”’ from Per- netty Voy. au Malouines. It is perfectly obvious therefore that the Hocitzanatl of Fernandez is the one and only original of Corvus mexicanus since all the references by Gmelin go back to this bird and his diagnosis alone is quite insufficient to identify the species. I give the original description of the Hocitzanatl taken from the Latin edition of the Nova Plantarum Animalium et Mineralium Mexicanorum Historia, published at Rome in 1651. 7—Proc. Broun. Soc. WasH., Vou. 42, 1929. (121) 122 Proceedings of the Biological Society of Washington. “‘Cirea urbes versatur Hocitzanatl, essetque monedulis nostratibus pror- sus similis, nisi eas vinceret corporis magnitudine & prolixitate caudae (qua vel Picis ipsis est par) & e nigro colore in caeruleum splendentum - paulisper inclinaret. Garrula est, altaeque vocis, sonorae, crura sunt nigra & mediocriter loga ac pedes in quaternos fissi digitis, armatos unguibus prolixis, ac nigris; alimoniam iucundam praebet, atramque, pertinentem ad succum melancholicum, sunt qui Cacaxtototl vocent.’’ To my mind this description of a bird the size of a jackdaw with a tail as long as a magpie, having a high-pitched sonorous note can not apply to a crow even if the color is black inclining to iridescent blue. Apparently Latham’s calling the bird ‘Mexican Crow”’ was responsible for Gmelin naming the bird Corvus mexicanus, and once the bird was in the genus Corvus, ornithologists found it much more convenient to apply the name to a crow from Mexico than to take the trouble to go back to the original sources and find out what it was really all about. There is just one Mexican bird to which the description of the Hocit- zanatl can apply and that is the Great-tailed Grackle, at present known as Megaquiscalus major macrourus, and having so identified Corvus mexicanus a far reaching trail of consequences arises. : In 1831 Lesson, in his Traité d’Ornithologie, page 433, diagnosed the Genus Cassidix for the first time, giving as the only species the ‘‘Cassique a mantelet’’ for which Corvus mexicanus Gmel. and Cassicus niger Vieill. Gal. des ois. pl. 89 ? were cited as synonyms. His generic diagnosis is without much question referable to a Rice Grackle but his synonymy is not, —Corvus mexicanus being a Great-tailed Grackle and Cassicus niger is certainly some sort of Holoquiscalus. In 1840 Gray designated as the type of Cassidiz, “C [assidix] mexicanus (Gm.) Less.” [=Corvus mezi- canus Gmel.] Thus Cassidix being of earlier date than Megaquiscalus (Cassin 1866) must replace it, and Corvus mexicanus Gmel. being an earlier name for Quiscalus macrourus Swains. and also of earlier date than Quiscalus major Vieill. 1819, the boat-tailed Grackles will stand as: Cassidix mexicanus mexicanus (Gmel.) i major (Vieill.) obscurus (Nels.) graysoni (Scl.) nelsoni (Rigw.) assimilis (Scl.) tenuirostris (Swains.) nicaraguensis (Salv. & Godm.) This action is three-fold in its immediate effect on nomenclature, for in the first place the Rice Grackles will require a different generic name, furthermore the bird hitherto known as Casstdiz oryzivora mexicana (Less. ) must be renamed since Lesson named no such bird but merely cited Gmelin’s Corvus mexicanus in the synonymy of his ‘“‘Cassique a mantelet,’’ and it is quite obvious that the same name can not be used for two different species, and lastly the mexican Crow must receive a name, since it never really had one. Peters—The Identity of Corvus Mexicanus Gmelin. 123 There seems to be no generic synonym available for the Rice Grackles. Ridgway, Birds No. & Mid. Am. pt. 2, 1902, p. 196, cites Scaphidura Swainson (Classif. Bds. 2, 1837, p. 272) as a synonym, but after consider- able hesitation and on the advice of Dr. Richmond, I have considered it a lapsus or emendation of Scaphidurus Swainson (Philos. Mag. N. S. 1, no. 6, June, 1827). Scaphidurus is asubstitute name for Quiscalus and, under Art. 30, par. f of the International Code, takes the same type, so Scaphidurus is a synonym of Quiscalus as is also Scaphidura (if regarded as an emendation or lapsus). The Rice Grackles therefore being aeinlens I propose the name Psomocolax for Cassidix of authors nec Lesson, with Oriolus oryzivorus Gmelin as the type. The Mexican Rice Grackle I name Psomocolax oryzivorus impacifus, subsp. nov. Type, adult male, no. 102320, Museum of Comparative Zoology, from ~Pasa Nueva, Vera Cruz, Mexico; collected 22 April, 1901, by A. E. Col- burn and P. W. Shufeldt. Characters.—Similar to Psomocolax oryzivorus oryzivorus (Gmelin) but averaging larger, plumage of adult male uniformly glossed with violet without trace of bronze. Remarks: The three races of Psomocolax oryzivorus with their characters and distribution are: P. o. impacifus nob. Size medium, wing of o 183-210, bill 37-38.5; gloss entirely violaceous sometimes with a wash of steel blue, but never bronzy. Southern Mexico to western Panama. P. o. violeus (Bangs). Size larger, wing of o’ 196-210; bill 37-40; viol- aceus gloss confined to pileum and posterior upper and underparts; mantle, neck ruffs and anterior underparts strongly glossed with bronze. Canal Zone through northern Colombia to northeastern Venezuela. P. o. oryzivorus (Gmel.). Size small, wing of o 180-190, bill 34-36, coloration like violeus. Probably from the Guianas south through tropical Brazil to Paraguay and north-eastern Argentina. This leaves but one more change to make, that of naming the Mexican Crow. It may be called: Corvus imparatus, sp. nov. Type: Adult male, no. 49840, Museum of Comparative Zoology, from Rio La Cruz, Tamaulipas, Mexico, collected 24 June, 1909, by Frank B. Armstrong. Characters.—Similar to Corvus ossifragus Wilson but much smaller, plumage much more brilliantly glossed; bill relatively weaker and more slender; nasal plumes shorter and less dense. In conclusion I tender my warmest thanks to Dr. C. W. Richmond not only for his advice and guidance on the questions here involved, but on the many other occasions when his valued counsel has been sought and freely given. hv poy Vol. 42, pp. 125-128 Beit 4 + March 30, 1929 PROCEEDINGS Ry ee OF THE ee BIOLOGICAL SOCIETY OF WASHINGTON NOTES ON THE SIPHONAPTERAN GENUS CATAL- LAGIA ROTHSCHILD, INCLUDING THE DE- . SCRIPTION OF A NEW SPECIES. BY, HE. EWING. _ The genus Catallagia was established in 1915 by the late Hon. N. Charles Rothschild for a species described by the late Professor Charles F. Baker as Pulex charlottensis. Baker’s charlottensis was taken from a mouse nest at Massett, Queen Charlotte Islands, and although described as a Pulex, it was soon transferred to Odontopsyllus Baker. Here it remained until the genus Catallagia was erected for it and three other species including one new one which Rothschild described as decipiens. This latter species was taken from various Murid hosts and at the following places: Horse Creek, Upper Columbia Valley, British Columbia; Blackfalls, Alberta; British Columbia (no other locality given); and Red Deer, Alberta. The other two species included in Rothschild’s Catallagia are telegoni Rothschild, described in 1905, and wymani Fox, de- scribed in 1909. The first of these two species was taken from a meadow mouse, Microtus drummondi, in the Upper Columbia Valley, and the second was taken from the California field mouse, Microtus californicus, at San Francisco, California. Thus there are known up to the present four species of Catallagia, all being taken in western North America. This year, however, the writer has to report a species from the eastern part of the United States. It is a new one taken during the summer of 1928 in Maine, by W. J. Haniilton, Jr. This species, like all of the other known Catallagias, was found on a Murid host. Does the finding of this single species of Catallagia in Maine indicate that the genus Catallagza is dis- 8—Proc. Brot. Soc. Wasu., Vou. 42, 1929. (125) eee ed Geil eh 126 Proceedings of the Biological Society of Washington. tributed transcontinentally, and will it be found on Murid hosts throughout most of the Boreal Life Zone? As stated by Rothschild, Catallagia is closely related to Ceratophyllus. It is, however, distinct in a number of im- portant respects; in having a patch of short spines on the inner surfaces of the hind coxae, in having four instead of five pairs of lateral plantar bristles on the ventral surface of the fifth seg- ment of the hind tarsus, and in having a peg-like frontal tubercle instead of the common type, as well as in some other respects. The types of Baker’s charlottensis and Fox’s wymani are in the United States National Museum and have been examined by the writer. In addition to giving a description of the new species found, keys are given to the males and females of Catallagia species. Key To THE Known MALEs oF THE GENUS CATALLAGIA. 1.

Doctor David C. Graham, whose explorations in the province of Szechwan, China, have added so much to our knowledge of its herpetological fauna, has recently sent to the National Museum an unusually interesting new ophidian species. It is an exceedingly handsome snake of a rather pale neutral color ornamented with bold black bands on the face and head, and the body festooned across the back with a narrow black ribbon studded with bright round beads of a whitish color. This pattern unlike that of related species, in which it fades and disappears in the fullgrown specimens, seems to retain its brightness in the present species, as the specimen received is an adult male over three feet long. The name has reference to the unique ornamentation. Elaphe perlacea, new species. Diagnosis: Scales at the middle of the body in 19 rows, about 13 keeled; anal divided; no subocular, anterior temporal one; supralabials 7; head pattern with a black prefrontal band bifurcating at the eye; body with narrow black cross-bands enclosing whitish scale centers; underside | ‘checkered. Type: U.S. National Museum No. 76257. Type locality: Yachow prefecture, Szechwan, China. Description of type-specimen: Adult male; U.8. N. M. No. 76257; Yachow province, Szechwan; June, 1928, D. C. Graham, collector. Rostral much broader than high, broadly visible from above, sutures with internasals much longer than suture between the latter; internasals small, much broader than long, about two-thirds the size of the prefrontals, which are broadly in contact with supraocular; frontal as long as its distance from tip of snout, slightly longer than its width and the interparietal suture, somewhat broader in front than behind; parietals as long as frontal; nostril large between two subequal nasals; loreal trapezoid, much longer than high; one preocular widely separated from frontal; no subpreocular; two 9—Proc, Bron. Soc. WasH., Vou. 42, 1929. (129) 180 Proceedings of the Biological Society of Washington. small postoculars, both in contact with parietal, upper not in contact with anterior temporal; temporals 1+2; supralabials 7, third and fourth enter- ‘ing eye; 3 lower labials in contact with anterior chin-shields, which are slightly longer than the posterior; posterior chin-shields separated from each other by two small scales, in contact with one sublabial; 19 rows of scales, 11 to 13 rows very distinctly keeled, four lateral scales smooth anteriorly and three at midbody; towards vent and on tail all scales keeled, ventrals 229, obtusely angulate laterally; anal divided; 69 pairs of sub- caudals. Color (in alcohol) tawny gray, more plumbeous on the sides and underneath; upper side of body and tail with a pattern of narrow black equidistant cross-bands formed by the back tips and bases of two adjacent scale rows the centers of most of the scales being whitish; each two cross- bands being joined at or on the ventrals so as to form about 37 oval rings, the effect being a continuous black garland studded with strongly con- trasting white beads; underside plumbeous checkered with black blotches edged with white; head pattern black, very distinct; a band from first labial through nostril across the suture between rostral and internasals; another similar but broader, from suture between third and fourth supra- labial through eye over posterior half of prefrontals, bifurcating in the eye projecting a broad black line backwards across postoculars, anterior half of first temporal to upper anterior part of sixth supralabial; a black A-shaped figure, the apex on the posterior half of frontal, extending back- wards over parietals where bifurcating, the outer branch extending across second row of temporals to seventh supralabial, the parallel with the interparietal suture to the neck; on the lower lip one black spot on the suture between third and fourth sublabials appear as a continuation of the ocular band; another smaller spot on suture between second sublabial and anterior chin-shield. Dimensions: On account of the hardness of the specimen the body can not be stretched sufficiently for very exact measurements. The total length is approximately 940 mm., tail 210 mm., total length 1150 mm. The ratio between body and tail is consequently about 4.5 : 1. Remarks: The present species has its nearest relative in the Japanese Elaphe conspicillata, from which it differs in various important characters. Thus the latter has invariably 21 scale rows with feeble keels on only nine rows. The scale-formula is otherwise almost identical, except that the type of the new species has 229 ventrals, a greater number than the maxi- mum recorded for the species from Japan. The head pattern is also the same, except that the arms of the parietal A are double and that a median occipital black line is absent. The body pattern differs considerably, however, apart from the fact that the marking disappears in the adult Japanese specimens, while it is strongly marked in the type of E. per- lacea, which is full grown. There is no reason to believe that any of the previous erroneous records of E. conspicillata occurring in China refer to the present species. 7. 0623 Vol. 42, pp. 131-142 March 30, 1929 PROCEEDINGS agi OF THE BIOLOGICAL SOCIETY OF WASHI NOTES ON THE SPIDERS OF WASHINGTO COUNTY, UTAH. BY R. V. CHAMBERLIN AND A. M. WOODBURY. The spiders listed in the present paper were taken mostly at two localities in Washington County, which occupies the extreme southwestern corner of Utah; namely, St. George and Zion National Park. While some specimens were col- lected by the senior author in 1923 and in 1927 by far the greater number were secured by Mr. Woodbury, who, during the summer season, has served as naturalist for Zion National Park for several years past. We plan through further collect- ing to bring the list for the Park in particular to essential com- pleteness. Types of the new species described are in the collection of the senior author. THERAPHOSIDAE. Eurypelma steindachneri (Ausserer). St. George. Females and immature specimens are referred tentatively to this species. DICTYNIDAE. Dictyna dactylata Chamberlin. St. George. Six females taken in 1925, 1926 and 1927. A form re- sembling volucripes but much smaller and with a different epigynum in which the septum typically ends caudally in a slender chitinous finger, though this may connect with the caudal rim which does not extend far laterad on each side as it does in volucripes. Dictyna volucripes Keyserling. St. George. One female referred to this species was taken several years ago by V. M. Tanner. 10—Proc. Biov. Soc. Wasu., Vou. 42, 1929. (131) 182 Proceedings of the Biological Society of Washington. Dictyna hoples Chamberlin. Zion National Park. One male. A species readily recognizable in the _male sex by the enormously long, curved, distally bidentate apophysis of the tibia of the palpus. This is longer than in armata Emerton in which also the tooth on the chelicera is farther removed from the base. Dictynoides sp. Zion National Park. One immature female taken in 1927 can not be safely referred to its species. SCYTOTIDAR. Loxosceles rufipes (Lucas). Zion National Park. Two females, not fully mature, seem to be this species. Plectreurys tristis Simon. Zion National Park. One young female. Diguetia canities (McCook). Zion National Park. One female of this highly interesting and rarely taken spider was secured in 1927.

The considerable series of lemmings from island and mainland localities in western Alaska, which has accumulated in the Biological Survey collection during recent years, supplies in- formation helpful toward clearing up some obscure points con- cerning the relationship between Dicrostonyx rubricatus and D. unalascensis. In the Proceedings of the Biological Society of Washington, March 14, 1900, vol. 2, p. 25, Dr. C. Hart Merriam described Dicrostonyx unalascensis from Unalaska Island in the Aleutian Chain. His type was a broken skull, one of several taken from owl pellets near the village of Unalaska. Since then unsuc- cessful efforts have been made by several naturalists to capture some of these lemmings at the type locality, in order that their color and other general characters might be determined. Owl pellets found there, however, have continued to yield skulls until the Biological Survey collection now contains more than 130 of them. Fortunately from 1920 to 1924, while investigating the reindeer herd of the Biological Survey on Umnak Island, lying across a channel about 6 miles broad from the western end of Unalaska Island, Donald H. Stevenson, of the Biological Survey, located runways of lemmings in a few limited areas on the eastern part of the island, and during the months of No- vember and December in different years, secured a series of 14 specimens of which more than half are adults. All appear to be in full, heavy winter pelage, some having been taken as late as December 14. It is interesting to find that adults and young are in varying shades of nearly uniform brownish gray 11—Proc. Broun. Soc. Wasu., Vou. 42, 1929. (148) 144 Proceedings of the Biological Society of Washington. pelage, without a trace of the white winter coat so commonly worn by the members of this genus. In addition the claws of the two middle toes on the front feet are dusky horn color, and although slightly enlarged they are much less than one-half the size of the great claw of rubricatus and hudsonius, in their winter condition In fact the Umnak Island specimens must be examined closely to determine the existence of any claw development, thus strongly contrasting with the extraordinary winter claws in the species named. A white specimen of young rubricatus, about one-fourth grown, taken in December at Chignik on the south coast of the Alaska Peninsula, has the typical winter claw development of that species. No summer skins from Umnak Island are available to com- pare with rubricatus, but the winter color of the upperparts of the eight adult Umnak Island specimens is in general dingy gray with a slight tinge of buffy brown, overlaid by a very slight wash of reddish on sides and top of shoulders; the under- parts are dull buffy or buffy whitish. The characters given above indicate that we have on Unalaska ~ and Umnak Islands an insular species of lemming, with suf- ficient differences between the skulls to warrant recognizing the Umnak Island animal as a subspecies of D. uwnalascensis. It should be noted here that three summer specimens of collared lemmings from Unimak Island, adjacent to the western end of the Peninsula of Alaska, in the Biological Survey collection — are close to typical D. rubricatus, without signs of intergrada- tion toward D. unalascensis in size or color. The retention of a brown pelage in winter by the Umnak lemming, in place of the usual white garb of the other members of the genus Dicrostonyx, may be reasonably attributed to the response of this species to the milder winter climate of its habitat. While Umnak Island lies in a very stormy region, yet zero temperatures are uncommon, and while snow falls at intervals during more than six months each year, sometimes remaining on the ground for weeks, yet not infrequently during the winter months the ground lies nearly or quite bare. This new subspecies is named in honor of the late Donald H. Stevenson, who collected the specimens mentioned here under great difficulties. Measurements in millimeters. Proc. Brot. Soc.

Type from Umnak Island, Alaska, No. 235552, 9? adult, U.S. National Museum (Biological Survey collection), collected by D. H. Stevenson, December 14, 1920. General characters.—Largest of the known American lemmings, with a massive skull; apparently does not take on a white winter pelage, and lacks the great winter development of the two middle claws on fore-feet so conspicuous in other species of the genus. Skull as in D. unalascensis but larger and heavier, with interparietal proportionately longer; supra- orbital ridges in adults more closely approaching, sometimes nearly uniting to form a median ridge; upper incisors more exserted, heavier and more decurved and less projecting at tips. Skull much larger and more massively proportioned than in D. rubricatus, with interorbital ridges more strongly developed. - Color of type.—Upperparts nearly uniform dull, pale, buffy brown, slightly grayer on rump; dull, rather poorly marked, chestnut patch cover- ing ears; a thin, blackish, median, dorsal line from nape to tail; a pale chestnut wash on sides of neck, fading posteriorly into a buffy line ex- tending along sides of body; underparts pale dull buff; an irregular dull grayish white patch across posterior part of crown, and grayish white hairs about nose—these last being marks of individual variation. Skull of type.—Larger than in D. unalascensis, with interparietal longer; incisors heavier and more decurved. Measurements of type.—Total length, 165; tail vertebrae, 12; hind foot, 20. Skull: Condylobasal length, 33.7; zygomatic breadth, 23.1; interorbital constriction, 4.3; length of nasals, 10.2; alveolar length upper molar series, 8.5. Remarks.—The eight adult specimens of D. wu. stevenson have the upper- parts of the head and body a nearly uniform, dull, buffy brownish, a little grayer in some and darker in others; the ears are covered by a small, not strongly marked patch of dull chestnut; a median dark line usually present in the young, is usually absent or obsolescent, in the adults. Some indi- viduals are marked by irregular, dingy, grayish white patches on crown or nape; sides of nose, chin, and throat usually grayish. Sides of neck, lower shoulders, flanks and outside of front and hind legs varying from pale to dingy buffy; the underparts of the body paler buffy than the flanks, some- times dingy grayish with only a trace of buffy. The front claws are only slightly enlarged about as in D. rubricatus in summer. A series of six half-grown young among the specimens of stevensoni, taken between October 19 and December 1, are very similar to the adults in their generally dull buffy brown color of the upperparts, with a tinge of reddish never strongly marked and varying in tone individually. Indis- tinct chestnut ear spots and a dark median dorsal line usually present, but absent or pale in some. Underparts pale buffy, varying in shade. Skulls of both D. unalascensis unalascensis (Pl. III, figs. 1-2) and D. uw. —— 146 Proceedings of the Biological Society of Washtngton. stevensoni are distinctly larger and more massively proportioned than those of typical Dicrostonyx rubricatus (Pl. IT, figs. 5-6) from near Hooper Bay and Point Barrow on the mainland of Alaska, or in any of the Ameri- can collared lemmings of which D. hudsonius appears to be the smallest. Postorbital process characteristic of Dicrostonyx proportionately and actually heavier and more prominent than in the others; rostrum pro- portionately heavier and interparietal averaging proportionately larger. Molar series longer and broader than in the other species of Dicrostonyz, with pattern of enamel folds similar in general character to that of D. rubricatus, but with closed areas on all upper molars more compressed in the antero-posterior plane, so they have a distinctly less deltoid and more spur-like form. Even more than in others of this group, both forms of D. unalascensis have marked supraorbital ridges which with age nearly join on median line. 7-0672 Vol. 42, pp. 147-152 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHI FOUR NEW POCKET GOPHERS OF THE GENUS HETEROGEOMYS FROM MEXICO. BY E. W. NELSON AND E. A. GOLDMAN. In ‘Monographie Revision of the Pocket Gophers” (North Amer. Fauna, No. 8, January 31, 1895) Merriam named the genus Heterogeomys, to which he assigned H. hispidus and H. torridus as distinct species, with type localities only a few miles apart, but at different altitudes, and in differing general faunal areas. H. hispidus inhabits the humid “cloud”’ forest region on the seaward slope of the lofty Cofre de Perote, while the type locality of H. torridus is on the adjoining arid tropical coastal plain. Heterogeomys lanius Elliot (Proc. Biol. Soc. Washington, vol. 18, p. 235, Dec. 9, 1905) was later described from a high altitude on the southeastern side of Mount Orizaba, about 50 miles southwest of the type locality of hispidus. Comparatively few specimens of this genus were available for study by Merriam. Subsequent field work has resulted in the accumulation of specimens from a number of localities extending the known range of the genus northward to eastern San Luis Potosi, and into several other Mexican states. Study of material now at hand has resulted in the conclusion that H. hispidus and H. torridus are very closely related sub- species. H. lanius is imperfectly known and may be retained for the present, with full specific rank. Four new subspecies are described here, and the forms assignable to the genus, with type localities, are as follows: Heterogeomys hispidus hispidus (Le Conte)................--------.----------0-------- Near Jalapa, Vera Cruz, Mexico.

Goldman, September 9, 1896.- Origi- nal number 10130. Distribution.—Eastern slope of the tableland and mountains to 7,000 . feet in Queretaro, and lower elevations in San Luis Potosi. General characters.—A large subspecies, allied to H. h. hispidus and H. h. torridus, but upper parts in fresh pelage near chestnut brown (near Mars brown in hispidus and torridus) and underparts a lighter, russet brownish tone; skull more angular and massive, the upper outline de- cidedly concave in adult males, and differing in details of structure. Pelage similar to that of hispidus in density and texture, denser especially on under parts, and softer than in torridus. Color.—Type (partly worn pelage): Upper parts and outer sides of limbs near Prout’s brown; under parts light cinnamon brownish; feet and tail scantily clothed with brownish hairs, the tail becoming naked at tip. Specimens in fresh pelage near chestnut brown above, and dull russet brownish below. Skull.—Similar in size and general form to that of H. h. torridus, but more angular and massive; frontal region in adult males more depressed, the upper outline concave; zygomata broader and heavier, the squamosal arm overlapping jugal strongly developed, with a prominent knob-like end (end more tapering in torridus); lambdoid crest higher, more abruptly upturned, the squamosal portion heavier, more strongly inclined forward; auditory bullae rather broad, but usually less extended below level of surface of basioccipital; dentition about the same. Compared with that of H. h. hispidus the skull is shorter and broader, with rostrum more flattened, zygomata more widely and squarely spreading anteriorly, and it differs otherwise in about the same details as from torridus. Measurements.—Type: Total length, 343 mm.; tail vertebrae, 84; hind foot, 48. Two adult male topotypes, respectively: 315-340; 75-74; 47.5-47.

Remarks.—Heterogeomys h. concavus occupies a northern extension of _ the range of the species. It appears to be most closely allied to H. h. torridus in cranial characters, but the pelage in density and softness is more like that in typical hispidus which also inhabits mountain slopes at alti- tudes above 5,000 feet. Denser, softer pelage is apparently associated with the lower temperatures prevailing at the higher levels, while thinner, harsher pelage characterizes typical torridus which is found at low eleva- tions. Specimens from the lowlands of San Luis Potosi are similar to torridus in thinness and harshness of pelage, but in color and cranial characters are nearer to the present form to which they are referred. Specimens examined.—Total number, 9, as follows: Queretaro: Pinal de Amoles (type locality), 7. San Luis Potosi: Tancanhuitz, 1; Valles, 1. Heterogeomys hispidus isthmicus, subsp. nov. ISTHMIAN POCKET GOPHER. Type.—From Jaltipan, Vera Cruz, Mexico (altitude 100 feet). No. 78062, @ adult, U. S. National Museum (Biological Survey collection), collected by E. W. Nelson and E. A. Goldman, May 2, 1896. Original number 9574. Distribution.—Semi-forested coastal plains on the Gulf side of the Isthmus of Tehuantepec, in southern Vera Cruz, Mexico. General characters.—A large subspecies most closely allied to H. hispidus torridus, but color lighter brown, and cranial characters, especially the remarkable sinuosity of the lambdoid crest, distinctive. Similar to typical hispidus, but skull with shorter rostrum, and differing otherwise in about the same characters as from torridus. Color.—Type (fresh coat replacing worn pelage on anterior part of body and along median line of back): Upper parts in fresh pelage near chestnut brown, worn portions a lighter cinnamon brownish tone; a nar- row transverse white stripe extending from median line on lower part of back to upper part of left flank where it is interrupted, and appears again as a stripe below across abdomen; under parts in general, limbs, and feet thinly haired, light brownish; tail naked, dull flesh-colored. Skull.—Similar to that of H. h. torridus, but median part of lambdoid crest with a marked crescent-shaped anterior deflection, maxillary arm of zygoma heavier, encroaching upon premaxillae which are correspondingly narrowed posteriorly; nasals usually longer; dentition about the same. Compared with that of typical hispidus, the rostrum is shorter and flatter, and the skull differs otherwise about as from torridus. Measurements.—T ype: Total length, 325 mm.; tail vertebrae, 86; hind foot, 46. Average and extremes of four adult male topotypes: 320 (309- 334); 89 (82-99); 46.

Skull (type): Condylo- basal length, 59; length of nasals, 24.4; zygomatic breadth, 41.5; greatest _— en al 150 Proceedings of the Biological Society of Washington. breadth across squamosals (over mastoids), 38.7; interorbital breadth, 11; alveolar length of upper molar series, 13.5. Remarks.—This subspecies is known only from the low, Gulf coastal plains on the Isthmus of Tehuantepec, the adjoining coastal regions to the east and west, as well as the interior, being occupied by other forms. While close relationship is evident it is readily distinguished from the other sub- species of hispidus by the abrupt, median, crescent-shaped, forward de- flection of the lambdoid crest. The distance from Jalapa and Chicaxtle, Vera Cruz, the type localities of hispidus and torridus respectively, is not great, and theform on the peninsula of Yucatan is different. The differen- tiation of isthmicus from torridus may be due to its isolation between the Papaloapam and the Grijalva rivers which, although not long, drain excessively humid regions and are of sufficient size to present effective barriers. Three specimens have a narrow white stripe extending from the median line on the lower part of the back down one of the flanks to a whitish area on the abdomen. In two of these it is on the left and in the third example on the right side. A similar marking is present in the type specimen on the left side, but is interrupted or faintly indicated on the middle of the flank. White markings occur sporadically in pocket gophers, but usually lack the regularity noted in this instance. In an adult male (No. 78061) the outer squamosal border, on both sides of the skull, bears a tapering, pointed process about 3.5 millimeters in length, directed up- ward and forward over the auditory meatus. ‘These peculiar processes, evidently affording additional muscular attachment, are not present in the other specimens from the same locality, and have not been observed in other pocket gophers. Specimens examined.—Sixteen, from localities as follows: Vera Cruz: Catemaco, 1; Jatipan (type locality), 15. Heterogeomys hispidus yucatanensis, subsp. nov. YUCATAN POCKET GOPHER.

Original number 14233. Distribution.—Lowlands of the Yucatan peninsula and northern Guate- mala. General characters.—A rather small subspecies, similar to H. h. hispidus and H. h. torridus, but smaller, with relatively longer tail; pelage thinner, under parts nearly naked; color lighter, light chestnut-brown, or inclining toward cinnamon brown (near seal brown in hispidus and torridus); skull differing in detail, especially the relatively broader and heavier maxillary arm of zygoma. Similar in color to H. h. isthmicus, but smaller and cranial characters distinctive. | Color.—Type: Upper parts (moderately worn pelage) near chestnut brown; under parts, limbs and feet nearly naked, the scattered hairs light brownish; tail dull flesh colored, with a few brownish hairs on proximal half, becoming naked distally. Nelson and Goldman—F our Pocket Gophers from Mexico. 151 Skull.—Similar in general form to those of H. h. hispidus and H. h. torridus, but smaller; maxillary arm of zygoma relatively broader, heavier, more decurved, the anterior margin turning more abruptly outward from rostrum and curving slightly backward to external angle; dentition much lighter, molariform toothrows decidedly shorter; premaxillae broad pos- teriorly as in torridus, with little or no encroachment by maxilla. Com- pared with that of H. h. isthmicus the skull is smaller and lacks the deep, median anterior deflection of the lambdoid crest distinctive of that form; molariform toothrows shorter; nasals broader posteriorly. Measurements.—T ype: Total length, 328 mm.; tail vertebrae, 101; hind foot, 47. Two adult female topotypes respectively: 308-303; 93-95; 45-44. Skull (type): Condylobasal length, 58.5; length of nasals, 22.3; zygomatic breadth, 38.5; greatest breadth across squamosals (over mas- toids), 36.8; interorbital breadth, 11.2; alveolar length of upper molar series, 11.7. Remarks.—The Yucatan pocket gopher has an extensive general range at very low elevations, probably embracing the whole of the peninsula for ~which it is named, and reaching southward to undetermined limits. The skulls examined from various localities indicate small bodily size which is not so evident from external measurements, owing to apparently greater length of tail and hind foot.

Nelson and E. A. Goldman, November 28, 1895. Original number 8682. Distribution.—Highlands of Chiapas and Guatemala from about 3,000 to 8,000 feet altitude, and descending to lower elevations in southern Tabasco. General characters.—Size large, color dark, pelage rather short, soft and velvety for a Heterogeomys. Similar to H. h. hispidus and H. h. torridus in size and color, but pelage shorter and softer, and cranial characters distinctive. Similar to H. h. isthmicus in size, but color darker, pelage softer, and skull differing in detail, especially the straighter outline of lamboid crest (deeply indented in isthmicus). Distinguished from H. h. yucatanensis by larger size, softer pelage, and cranial features, notably the relatively narrower rostrum. Color.—Type: Upper parts, and outer surfaces of limbs, near seal brown; under parts thinly haired, cinnamon brownish; hind feet and toes of front feet scantily clothed with brownish hairs; tail nearly naked beyond 152 Proceedings of the Biological Society of Washington. base, becoming entirely bare near tip, the dried skin dull flesh-colored. In one specimen a white spot, irregular in shape, appears on the middle of the abdomen. Skull.—Similar in general contour to that of H. h. torridus, but rostrum narrower, less flattened, the nasals rising more prominently above the level of the premaxillae; maxillary arm of zygoma heavier, more broadly ex- panded at outer angle; auditory bullae smaller, less inflated, not usually extending below plane of basioccipital; dentition lighter, molariform tooth- rows shorter. Differing from that of H. h. isthmicus in straighter, less deeply sinuous lambdoid crest, narrower rostrum, and lighter dentition. Contrasted with that of H. h. yucatanensis the skull is decidedly larger, with relatively slenderer rostrum, and less inflated auditory bullae. Measurements.—Type: Total length, 323 mm.; tail vertebrae, 8&6; hind foot, 48. Two adult female topotypes, respectively: 322-320; 84-79; 48-48. Skull (type): Condylobasal length, 58.5; length of nasals, 22.1; zygomatic breadth, 39.3; greatest breadth across squamosals (over mas- toids), 37; interorbital breadth, 11.8; alveolar length of upper molar series, 12.8. Remarks.—The range of this subspecies is in a region varying greatly in elevation and general topography. Specimens from the type locality and at the higher elevations elsewhere have softer, somewhat denser pelage than those from lower elevations as at Montecristo, Tabasco, but the latter do not appear to be satisfactorily separable. Two specimens of Heterogeomys from Guatemala were referred by Merriam (North Amer. Fauna, No. 8, p. 185, Jan. 31, 1895) to H. torridus, although he pointed out an apparent difference. These specimens are referred by us to the form here described, from which they appear indistinguishable.

BURT. The genus Verticaria has been separated from Cnemido- phorus on the basis of only one character, namely, the fronto- parietal or postfrontal plate. In Cnemidophorus this shield is characteristically divided into two or more plates, while in Verticaria it is supposedly single. The union of two head plates, such as the frontoparietals in this case, may usually be regarded as a poor generic distinction if used alone. Even though that - character be fairly constant in a small series, a detailed ex- amination of a large number of individuals, especially if they represent wide-ranging species, is fairly certain to bring to light numerous intermediates in both the primitive and derived stocks. Thus, the frontoparietals of Cnemidophorus tessellatus tessellatus are rather frequently partly united into one scute (Mus. Vert. Zool. Univ. Calif. Nos. 3195 and 3216) and some- times they are entirely united or nearly so (Calif. Acad. Sci. Nos. 43223 and 42459). This line of variation in Cnemi- dophorus tessellatus tessellatus tends toward the production of a Verticaria, such as has recently been found by Van Den- burgh and Slevin (1921) in Vertecaria ceralbensis from Ceralbo Island, Gulf of California, Mexico. So obvious is this rela- tionship that the writer upon considering its degree of morpho- logical specialization believes Verticaria ceralbensis to be directly derived from Cnemidophorus tessellatus tessellatus. The frontoparietals of the much smaller Verticaria hyperythra 1Contribution from the Zoological Laboratory of the University of Michigan. 13—Proc. Brot. Soc. Wasu., Vou. 42, 1929. (153) if frus EO 154 Proceedings of the Biological Society of Washington. stock may occasionally be divided into two parts. A number of such variants have been recorded during this study for Verticaria hyperythra hyperythra (Calif. Acad. Sci. Nos. 53555, 53569, and 57539; U. S. N. M. No. 12613: and’ M27 G3 No. 569), but none have been found in Verticaria caerulea or V. picta. In addition, Cnemidophorus depper deppet of Mexico has varied in the opposite direction by producing individuals with one frontoparietal only partly divided (Amer. Mus. Nos. 18959, 18924, 19188, and 19186) or with the two usually separate elements completely united (Calif. Acad. Sci. Field No. 6045 from Mixtequillo, Oaxaca, Mexico). It is significant that the Verticaria hyperythra group is related to the depper and per- plexus stocks of Cnemidophorus and not to the tessellatus group as is Verticariza ceralbensis. Because of these divided rela- tionships within the supposed genus Verticaria, in addition to the inconstancy of the only distinguishing character, it is necessary to consider Verticarza a synonym of Cnemidophorus. The placing of Verticaria sericea Van Denburgh (1895) in the genus Cnemidophorus makes necessary the formulation of a new name, since it is now preoccupied by Cnemidophorus gularis sericeus Cope (1892). The writer recognizes the lizard hitherto known as Verticaria sericea as a subspecies closely allied to Cnemidophorus hyperythrus hyperythrus, and there- fore proposes that the form be henceforth designated as— Cnemidophorus hyperythrus danheimae,! new name. In order to make clear at this point the distinctions among the primitive genera of the Teiidae, with which Cnemidophorus is allied, the following key has been prepared.

London, 1859, p. 404) and drew all of his characters from it. He stated his belief that the supposed type of the genus in the British Museum is not that type at all but a substituted specimen of Kentropyx pelviceps. If this is the case, it is now impossible to determine whether the type was a male or a female. If it was a female, there is every reason to believe that the males would possess femoral pores, since in certain other genera of the Teiidae the disappearance of these organs is confined to the female sex only. If such a sexual difference is found, either a new generic split must be formulated, or Monoplocus must pass into the synonymy of Kentropyz Spix, which apparently differs merely in the possession of femoral pores in both sexes. 7 7 — —<———“€ -- — — —- 156 Proceedings of the Biological Society of Washington. tails of classification and synonymy, may be expected to appear in the larger works.

Over twenty years ago, in fact, Howell in his revision of the genus? listed one specimen from Santa Cruz Island, Santa Barbara County, California, but the material remained scant indeed, if not unique, and the island animal has been assigned to Spilogale phenax phenax Merriam on general geographic grounds, without opportunity being afforded for critical study of specimens in series. More recently the naming of Spilogale phenax microrhina from the San Diegan district by E. Raymond Hall*, and its separation from the coastal animal phenax of northwestern ) California, has lent added interest to the capture and study of the animal from these islands which have been isolated from the mainland for such untold centuries. | Luckily material in adequate series, particularly from Santa Rosa Island, has become available in the last year or so, largely through the efforts of H. H. Sheldon and Paul Trapier. Mr. | Sheldon in particular has made a number of short trips to | Santa Rosa and Santa Cruz Islands in my behalf. In the study of the resulting material comparative use has been made not only of some 37 specimens in local collections, but also a series of topotypes of both phenax and microrhina in the University of California collections.

Raymond Hall, Curator of Mammals in the Museum of Vertebrate Zoology. - Two additional skulls-without-skins from Santa Cruz Island — have been kindly loaned me by D. B. Rogers of the Santa Barbara Museum of Natural History, and have supplemented our own limited series from that island in important fashion. When this combined material was assembled for study it became quickly evident that the island animal does not closely resemble the San Diegan form microrhina, which pushes up the mainland at least as far as Ventura County. Instead, the Santa Rosa and Santa Cruz Island series which seem to differ from each other in no essential respect, are closer, particularly in tail proportion, rostral region and external nares, to the northern form phenax. Looking at a map of the California coast and remembering the persistence still on near-by San Miguel Island of the Northern Sea-Lion (Eumetopias jubata) and remembering, too, the presence on the adjacent mainland of Pleistocene remains of northern trees such as the Monterey Pine, etc., it need not surprise us unduly to find this isolated colony of skunks perpetuating to some extent the characters of the race which is now found in northwestern California. If it does not resemble the form microrhina now found on the near-by mainland of Ventura County, may it not at least logically be suggested that the latter has perhaps come in as an intrusive element, spreading north and west with the change of conditions from humid to more arid on that part of the coast. Further study, however, shows that many differences set the island series off sufficiently from the closely related phenax to demand its naming. It may be known as follows: Spilogale phenax amphialus, subsp. nov. CHANNEL ISLANDS SPOTTED SKUNK Type.—Male adult; no. 13,400, collection of Donald R. Dickey; 2% miles north of ranch house near coast, Santa Rosa Island, Santa Barbara County, California; November 6, 1927; collected by H. H. Sheldon; origi- nal no. 14. Characters.—Externally the island animal has the short total length of microrhina, but differs strikingly from it in having the tail not long as in that form, but even shorter both actually and relatively than the short- tailed northern form phenaz. Dickey—S potted Skunk of Southern California. 159 Cranially amphialus has a comparatively massive skull, nearer in general to phenax than to microrhina, but differing from phenax in being shorter and more compact posterior to the supraorbital processes, with sagittal and lambdoidal ridges developed into striking crests; mastoid bullae as viewed from the side rounder, more compact and sharply tilted upward posteriorly; dentition lighter throughout, canines shorter and line of cingulum closer to alveolar border. Measurements of type.—Total length, 426 mm.; tail, 121; hind foot, 48. Skull: condylo-basal length, 57.1; occipito-nasal length, 51.0; width of opening of external nares, 6.8; zygomatic breadth, 37.8; greatest mastoid breadth, 33.9; interorbital constriction, 16.9; palatal length, 23.0; post- palatal length, 28.5; length of tooth row (c! to m! inc.), 18.6. Range.—Santa Rosa and Santa Cruz Islands, Santa Barbara County, California. Association, chiefly cactus patches, on Santa Rosa at least. Remarks.—Since intergradation with mainland species is now obviously impossible and since overlap in composite characters is not yet fully demon- strated, some might urge the desirability of describing amphialus as a species. However, the hiatus is so small as to lack significance in a group that is as variable as the Mustelids, and in addition, I am myself so con- vinced that phenax and amphialus are of common stock that the use of the trinomial gives to my mind a far truer picture of the situation. i, ee } De eas WER FRM Wik i Chino ans Bed STA AD, Cael Vol. 42, pp. 161-164 May 3, 1929 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHIN DESCRIPTIONS OF FOUR NEW BIRDS FROM “8S MOUNTAINS OF NORTHERN SIAM. BY 2.) EL RIUM Y While carrying on an investigation of the fish resources of the country for the Siamese Government, Dr. Hugh M. Smith has been making a collection of birds in his spare time and generously presenting the results of his labors to the U. S. National Museum. In November and December of last year Dr. Smith visited the Khun Tan mountains, near the northern boundary and collected on Doi Angka (or Doi In- tanon), the highest mountain in the country, which rises to 8500 feet, and on Doi Sutep (5600 feet). He was the first Caucasian to ascend Angka. The birds collected on this trip have been recently received and many of them appear to repre- sent forms not previously recorded from Siam. The following four are apparently new and are herewith described: Niltava grandis nobilis, subsp. nov. Type.—Adult male, U. S. National Museum, No. 311593, Doi Angka, Siam, at 6000 feet, December 4, 1928, collected by Hugh M. Smith (origi- nal number 2672). Similar to Niltava grandis grandis, but with the blues above somewhat lighter and brighter; outer surface of closed wing more extensively edged with blue, and the breast and belly more Sheena dusky violet blue. Wing, 105.5; tail, 91; culmen, 14 mm. Remarks.—A pair, tsikeon on the same day at the type locality. The male more nearly resembles Niltava grandis decipiens in color, but the blues are not quite so purplish. In size it agrees with Niltava grandis grandis. At present I have no female of typical grandis for comparison, but the female of nobilis is quite different from the same sex of decipiens. It is not so deep a brown (tawny olive instead of snuff brown); the nape is barely tinged with grayish, instead of the whole pileum being dusky violet-blue; 1Published by permission of the Secretary of the Smithsonian Institution. 15—Proc. Bron. Soc. Wasu., Vou. 42, 1929. (161) 162 Proceedings of the Biological Society of Washington. the throat is cinnamon buff, much lighter than the chest, instead of being nearly of the same color, and there are numerous other differences. This can hardly be Niltava grandis griseiventris La Touche (Bull. Brit. Orn. ~ Club, 42, 1921, p. 14), from southeast Yunnan, which is described as being grayer on the lower abdomen with less blue edging to the wing, while in the present race the conditions are reversed. Niltava smithi, sp. nov. Type.—Adult female, U. S. National Museum, No. 311595, summit of Doi Sutep, Siam, December 15, 1928, collected by Hugh M. Smith (original number 2769). Similar to Niltava sundara denotata, but jugular patch deep colonial buff instead of white; outer edging to wing-feathers saccardo umber in- stead of sayal brown, with the unexposed inner webs darker; inner webs of outer tail feathers chaetura drab, the middle pair and outer webs of the outer feathers saccardo umber instead of the whole tail sayal brown; upper tail-coverts dresden brown instead of tawny. Wing, 95; tail, 68; culmen, 12 mm. Remarks.—Only the type was taken. It is so different from the same sex in denotata that in my opinion it must represent a related species. | Zosterops palpebrosa vicina, subsp. nov. Type.—Adult male, U. S. National Museum, No. 311617, summit of Doi Sutep, Siam, December 15, 1928, collected by Hugh M. Smith (original number 2780). Similar to Zosterops palpebrosa palpebrosa, but lighter, more yellowish above, flanks less grayish, the chest suffused with a yellowish wash, with a _well pronounced yellow streak down the center of the chest. Wing, 54; tail, 36.5; culmen, 11 mm. Remarks.—This agrees with the description of Zosterops palpebrosa cacharensis Stuart Baker (Ibis, 1922, p. 144), but Ticehurst (Bull. Brit. Orn. Club, 47, 1927, p. 89), after examining the type, regards it as only an abnormal specimen of palpebrosa and states that the yellow abdominal streak is very faint and does not hold good in the majority of Assam specimens. As the mountain form of northern Siam is clearly different from palpebrosa, I have given it a name. Dr. Smith took a male and fe- male at the type locality on the same day. The female lacks the yellow suffusion on the chest, the belly is whitish, and the yellow line down the center of the chest is narrower than in the male, though well defined. Aethopyga nipalensis angkanensis, subsp. nov. Type.—Adult male, U. 8. National Museum, No. 311620, Doi Angka, 8400 feet, Siam, December 5, 1928, collected by Hugh M. Smith (original number 2692). Similar to Aethopyga nipalensis nipalensis, but chest grenadine red Riley—Four New Birds from Northern Siam. 163 instead of being only streaked with red; secondaries tinged on the outer -web with english red instead of warbler green. Wing, 52.5; tail, 59.5; culmen, 18 mm. Remarks.—Dr. Smith took two adult males and one adult female at the type locality, between 8000 and 8400 feet. The second male is like the type. The female resembles the same sex of typical nipalensis, but the head and throat are tinged with grayish and the secondaries are more deeply colored (near orange-citrine instead of citrine) on the outer web. The principal difference between the males of the present form and typical nipalensis is the grenadine red chest, without streaks, of the former. — ee ~~ | a —— i OU NID SOUS ASL ist iby pie Vol. 42, pp. 165-166 May 29, 1929 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHING DESCRIPTIONS OF THREE NEW BIRDS FRO THE MOUNTAINS OF NORTHERN SIAM. BY J. . RILEY. Further study of the collection of birds made by Dr. Hugh M. Smith in the mountains of northern Siam,? has made it necessary to name three additional forms. They may be de- scribed as follows: Hypothymis azurea montana, subsp. nov. Type.—Adult male, U. S. National Museum, No. 311580, Chiengmai, Siam, November 25, 1928, collected by Hugh M. Smith (original number 2613). . Similar to Hypothymis azurea styani,’but the blue of the head, throat, and back much lighter; the white of the lower-parts extending farther forwards; outer tail-feathers with white tips. Wing, 75; tail 74; culmen, 13.5 mm. Remarks.—Only the type was taken at Chiengmai, but a female was taken at Lampang. The male is quite different from the same sex of Hypothymis azurea atyani from south-east Siam of which a good series of males has been available for comparison. In montana the forehead and crown is ultramarine ash, the throat only a little deeper in color, while in styani the forehead and crown are dull violaceous blue shading off on the throat into deep dull violaceous blue. As a matter of fact the blue in montana is purer and lighter without the violaceous cast seen in styant. A few specimens of styani show the merest trace of white at the tips of the outer tail-feathers, while in montana the white tip is 4 mm. broad on the outer tail-feather, decreasing inwardly, almost disappearing on the fourth. The single female of montana does not seem to differ materially from the same sex of styani; the outer tail-feathers are more broadly tipped with whitish, but the series of this sex available for comparison is rather poor. It is rather surprising to find such a well-marked form of this genus in the highlands of Siam. 1Published by permission of the Secretary of the Smithsonian Institution. 2For previous paper, see: Proc.

National Museum, No. 311586, Khun Tan mountains, 4,000 feet, November 23, 1928, collected by Hugh M. Smith (original number 2591). Similar to Rhipidura albicollis albicollis, but the forehead, crown and lores slate color rather than sooty black; back deep neutral gray rather than mouse gray; lower-parts neutral gray rather than brownish gray, the feathers of the center of the chest and breast tipped with white making a rather broad whitish line down the center. Wing, 73; tail, 96; culmen, 11 mm. Remarks.—The above type has been compared with a female from Tenasserim, a male from Dehra, India, two females from south Annam, and three specimens from Yunnan. The latter are grayer, less brownish than those from India, but the forehead, crown, and lores are darker, more blackish than in celsa. In none of the Indian, Annam or Yunnam speci- mens is there an indication of the white line down the center of the chest and breast. It is rather surprising to find such a well-marked form of this species in the highlands of Siam. Sibia picaoides cana, subsp. nov. Type.—Adult male, U. S. National Museum, No. 311496, Doi Angka, Siam, at 7,500 feet, December 6, 1928, collected by Hugh M. Smith (origi- nal number 2704). Similar to Sibia picaoides picaoides, but a clearer, purer, and less brownish gray, especially below; the bill smaller. Wing, 114; tail, 166; culmen, 21.5 mm. Remarks.—Two males and one female were taken on Doi Angka, be- tween 5,000 and 7,500 feet, December 4—6, and a male and female on the summit of Doi Sutep (5,600 feet), December 15. This series is very uni— form and differs from a male from Upper Assam and an unsexed specimen, probably a male, from Sikkim as indicated above. The clearer, purer gray may be due to the freshness of the Siamese specimens, but the smaller bill alone is sufficient to establish the race. Iam indebted to the authorities of the Museum of Comparative Zoology for the loan of the Sikkim speci- men. The three males from Siam measure as follows: Wing, 114—-121.5 (118.8); tail, 166-183.5 (177.7); culmen, 19.5-21.5 (20.2). The two females from Siam: Wing, 118-122; tail, 167-176; culmen, 21-21.5. The male from Assam measures: Wing, 115; tail, 186.5; culmen, 22.5. The Sikkim specimen: Wing, 130; tail, 212; culmen, 23.5. Stuart Baker (Fauna Br. India, 2 ed. Vol. 1, 1922, p. 295) gives the culmen of picaoides as “about 24 mm.” PE Re ee ee Te Vol. 42, pp. 167-170 - June 6, 1929 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHI A NEW GENUS AND SPECIES OF AMPHIPOD FROM GRAND MANAN, N. B: | BY CLARENCE R. SHOEMAKER. Dr. Mary J. Rathbun while at Grand Manan, N. B., in 1898 made a collection of crustacea which she presented to the U. 8. National Museum. When looking over the amphipods of this collection I noticed specimens which were apparently new to science. They proved to be representatives of a new genus which I now designate as Amphzporeia, and briefly define.

Lower lip with inner lobes well developed, lateral angles prominent. Gnathopod 1, fifth and sixth joints equal in length, palm oblique, slightly concave and defined by a stout spine, finger as long as palm and bearing a few setae on the inner distal edge. Gnathopod 2, sixth joint shorter than fifth, palm oblique, convex, defined by a stout spine and armed throughout by low rounded teeth and short bristles, finger as long as palm and having a few slender setae on inner edge near apex. Peraeopods 1 and 2 alike, sixth joint longer than fifth, dactyl rather short, posterior margin of fifth joint with a group of long curved, bifurcate bristles and a few short simple ones, posterior margin of sixth joint with many short stiff bristles on lower half.

BY C. HART MERRIAM. Sixty years ago Dr. F. V. Hayden, when working in the Rocky Mountains, sent the Smithsonian Institution, from what is now the State of Colorado, the skull of a Grizzly bear, but omitted to mention the locality where it was obtained. In 1918 this specimen was described by me as the type of Ursus planiceps.1 In reference to its probable locality I stated: “Dr. Hayden worked in Colorado in 1869, mainly in the mountains and foothills of the east-central part of the State. In as much as two other grizzlies, bairdi and macrodon, inhabit the higher mountains of Colorado it seems highly probable that the home of planiceps was in the foothills or along the western edge of the plains.” (Ibid, p. 37 ftnote.) Recently the skull? of a grizzly from Middle Creek (south of Creede) near the head of the Rio Grande in southern Colorado, was sent to the Biological Survey by Charles L. Calar, one of its predatory animal hunters. It is labeled male, but has every appearance of a female. The sagittal crest is long and low, its posterior half only moderately elevated, and the canines are slender as in females of allied species. The molars also are dis- tinctly small—nearly as small as in the type of tezensis. Skull in general like planiceps the type of which, an old male, came from some unknown locality in Colorado. The Middle Creek skull is small and flattish, with flatly outstanding postorbital processes, flat narrow frontal shield, slightly and evenly sloping naso-frontal region; truncate nares; moderately spread- ing zygomata, and nearly flat palate. Rostrum compressed laterally immediately below the nasals; postorbital constriction hardly noticeable (only 66 mm.); frontal shield flat, conspicuously narrower than in navaho, thus agreeing with what would be expected in female planiceps; mandible similar to that of type of planiceps except for smaller size. 1N.

Holzworth of New York, who for several seasons ) has hunted big bears in Alaska and British Columbia and has succeeded in taking a remarkable series of photographs and f moving pictures of some of the big Alaska bears, has recently presented the Biological Survey with the skull of a large male Grizzly killed by him on the east slope of the Talkeetna Moun- tains near the headwaters of the Oshetna or the Black River.

National Museum, Biological Survey f Coll., from Talkeetna Mts., Alaska. Collected September 23, 1928, by John M. Holzworth. k Cranial characters —Compared with the type of cressonus: Basilar length : about 1% inch shorter; frontal region, though arched over orbits, decidedly less highly and less abruptly elevated; sagittal crest shorter and less pro- duced posteriorly; postorbital breadth (135 mm.) practically identical with that of cressonus, but interorbital breadth much less (85 contrasted with 96); zygomatic breadth about the same; anterior nares closely similar (rather truncate—not strongly sloping as in many species); palate flat with postpalatal shelf about as in cressonus; nasal region rather short, sloping strongly to frontals, which are not nearly so high as in cressonus; frontal sulcus very shallow, contrasting with the deeply sulcate groove of cressonus. he floor of the palate is broad and flat as in cressonus, show- i ing no trace of the dishing between the posterior molars that is noticeable in eximius, and the postpalatal shelf is distinctly shorter than in eximius, the interpterygoid notch broader. In the underjaw the infraangular surface is distinctly shorter than in eximius, and the interior border of the | ramus correspondingly longer. Hzimius has an exceptionally narrow ; skull giving it the appearance of greater length. This narrowness is 19—Proc. Brot. Soc. Wasn., Vou. 42, 1929. (173) 174 Proceedings of the Biological Society of Washington. | conspicuous in the frontal, interorbital, and palatal regions; and the rostrum is obviously longer and the nares more sloping (less truncate). The can- ines and molars as already stated are much smaller than in cressonus, in this respect agreeing far better with eximius. In fact, the length of the upper series is essentially the same as that of eximius, but the canines are materially smaller. In the lower jaw particularly, the canines are notably weaker (thinner basally) than in eximius, and the carnasial is distinctly smaller. In both jaws the teeth are too badly worn to admit of comparison of cusps. Last upper molar only slightly emarginate. In total length the Holzworth skull agrees essentially with eximius, and therefore is con- siderably smaller than cressonus. Measurements.—Condylo-basal length 357; basal length 339; basilar length of Hensel 333; occipito-sphenoid length 96; palatal length of Hensel 182; post-palatal length 150; foramen magnum to plane of last upper molar 180; occipito-nasal. length 322; greatest length of skull 374; zygomatic breadth 243; interorbital breadth 85; postorbital breadth 135; breadth of postorbital constriction 72; breadth across mastoids 189; breadth across squamosal shelves 166; facial length (front of nasals to plane of postorbitals) 136; length of braincase (plane of postorbitals to junction of lamdoid and sagittal crest) 111; greatest breadth of rostrum (over canine roots) 89; height of rostrum at front of pm. * 70; height of cranium above palate at plane of postorbital processes 115; height of cranium at plane of inter- sphencid suture 110.

Remarks.—Critical comparison of the skull of this specimen with those of other Alaska Grizzlies in the collection of the Biological Survey indicates that its nearest relative is Ursus cressonus from the Copper River region, the type of which was collected on Lakina River in 1914 by Capt. J. B. Hubrick. The Holzworth skull is of the normal generalized ursine type—lacking the highly arched frontals or other striking characters that distinguish some of the species. It is an old male, nearly if not quite as old as the type of cressonus, from which it differs in somewhat smaller size, less de- velopment of the sagittal crest, much less posterior overhang, less eleva- tion of the frontal shield, blunter and more outstanding (less decurved) postorbital processes, and much shallower frontal sulcus. The dentition is very much weaker than in cressonus, in this respect agreeing much more closely with Ursus eximius from Knick Arm, although the canines are even smaller and weaker than in eximius. In the Holzworth skull the molars are badly worn though much less so than in the type of cressonus. In cressonus the molars and canines are exceedingly broad and. massive while in Holzworth’s skull they are very much smaller and narrower. Proc. Brox. Soc. WasH., Vou. 42.

OF THE BIOLOGICAL SOCIETY OF WASHINGTON iN THE RACES OF SITTA PYGMABA. VIGORS.*. BY A. J. VAN ROSSEM. \\. ae As long as twenty-five years ago Mr. Ridgway (Birds of i North and Middle America, 3, 1904, p. 457, footnote) mentioned certain differences between the Pygmy Nuthatches of Mexico, the Rocky Mountain district and California, but lacking proper material from California, he did not attempt further subdi- vision of the species. The present writer has lately had the opportunity of examining adequate series from Lower Cali- fornia, the California coastal district, the Sierra Nevada and the Rocky Mountains, as well as a small series from Chihuahua. Most important of all is the fact that these series are made up for most part of birds in fresh, unabraded plumage whose characters are unobscured by wear. Comment on the geo- graphic characters displayed is given below. Sitta pygmaea pygmaea Vigors. MONTEREY PYGMY NUTHATCH. Sitta pygmaea Vigors, Zool. Beechey’s Voyage, 1839, p. 25, pl. 4 (Mon- terey, California). Range.—Coast of California from Monterey Bay north to Mendocino County. Remarks.—The range occupied by typical pygmaea is much more re- stricted than was formerly supposed. I have examined specimens col- lected at many stations from Monterey Bay to Mendocino City and Gualala, Mendocino County, but I know of no coastal records north of these two latter points. The record for Vancouver Island has been shown to be an error (Swarth, Birds of British Columbia, 1925, p. 115). The color characters distinguishing pygmaea from melanotis (see postea) are more brownish pileum and nape, combined with a relatively indistinct ocular streak which is never prominent and in extreme cases so nearly 1Contribution from the California Institute of Technology. 20—Proc. Bion. Soc. Wasu., Vou. 42, 1929. (175) 176 Proceedings of the Biological Society of Washington. concolor with the head as to be almost indistinguishable. From chihuahuae it is set off by much shorter wing, slightly larger bill and somewhat paler dorsal coloration. Forty-five specimens examined. Sitta pygmaea melanotis, subsp. nov. ROCKY MOUNTAIN PYGMY NUTHATCH. Type.—Male adult; no. 25,938 collection of Donald R. Dickey; Chiri- cahua Mountains, Cochise County, Arizona; September 19, 1919; collected by H. H. Kimball; original no. 3102. Subspecific characters.—Similar in size to Sitta pygmaea pygmaea, but top of head and nape decidedly darker and more slaty (less brownish); streak from bill through eye broader and often nearly black, contrasting strongly with the white or buffy white malar region. Differs from Sitia pygmaea leuconucha in decidedly smaller size and very much darker coloration. Range.—Rocky Mountain region of the United States (and British Columbia?) from the United States-Mexican boundary north, at least to northern Idaho; west to eastern Washington, eastern Oregon, the Sierra Nevada and south to the San Bernardino Mountains in southern Cali- fornia. Remarks.—The characters of this form are best developed in the Rocky Mountain region. The Sierra Nevada, San Gabriel and San Bernardino population is individually extremely variable, but adequate series from all these mountains show that in mass aggregate, they should be referred to this form. In southern California, intergradation with leuconucha is very gradual and birds from the extreme southern Sierras, Mt. Pinos, the San Gabriel and San Bernardino Mountains are definitely larger than northern Sierra and Rocky Mountain series. These intergrades have heretofore been called lewconucha, probably on account of their approach to that race in size. Ninety-seven specimens examined. Sitta pygmaea leuconucha Anthony. SAN PEDRO MARTIR PYGMY NUTHATCH. Sitta pygmaea leuconucha Anthony, Proc. Calif. Acad. Sci., Ser. 2, no. 2, October 11, 1889, p. 77 (San Pedro Martir Mountains, Baja, California, Mexico). Range.—San Pedro Martir Mountains, Lower California, north through the Sierra Juarez to the Cuyamaca and San Jacinto Mountains of Cali- fornia. Remarks.—Leuconucha in typical form occurs only south of the Lower California boundary. Birds from north of that point are somewhat inter- mediate toward melanotis, but a good series from the San Jacinto Moun- tains demonstrates clearly that leuconucha extends to that range, Compared with the other races, leuconucha is characterized by largest size, particularly of bill; paler, more ashy coloration of the upper parts, and least buffy underparts. I can not agree that the amount of white on the nape is of diagnostic value. Fifty-one specimens examined. Van Rossem—The Races of Sitta Pygmaea Vigors. 177 Sitta pygmaea chihuahuae, subsp. nov. CHIHUAHUA PYGMY NUTHATCH. Type.—Male adult; no. 115,701, Museum of Comparative Zoology; Mound Valley, Chihuahua, Mexico; September 3, 1905; collected by W. W. Brown, Jr. Subspecific characters.—Most nearly like Sitta pygmaea pygmaea and, like that form, with pileum tending to brownish rather than slaty, and streak through eye ill defined; but dorsal coloration slightly darker, wing longer and bill shorter. Measurements of type: wing, 67.0 mm.; tail, 35.0; culmen from base, 15.0. Remarks.—Ridgway has previously commented on the similarity in color of Californian and Mexican examples and the present investigation verifies his findings in this respect. Except for the longer wing, shorter bill and slightly darker color of the head, there is nothing to distinguish specimens from these two widely separated regions. They are, however, separated from one another by the wide territory occupied by melanotis. I have examined 20 specimens of this race, only 8 of which are suitable for purposes of camparison. All are from the State of Chihuahua, Mexico. In addition to the splendid series of Pygmy Nuthatches in the collection of Mr. Dickey at the California Institute of Technology, I wish to express my appreciation for the loan of specimens by the Museum of Comparative Zoology and the Museum of Vertebrate Zoology.

J. VAN ROSSEM. ¢ In describing a new race of Hartlaub’s Warbler from Nica- ragua, Messrs. Miller and Griscom (Am. Mus. Novit., 183, July 18, 1925, p. 7) pointed out that the genus Oreothlypis Ridg- way is not separable from Vermivora Swainson. The two species formerly included in Oreothlypis and now placed in Vermivora were Compsothlypis gutturalis Cabanis and Conirostrum super- ciliosum Hartlaub. As Cabanis’ specific name for the Irazt Warbler antedates by some fourteen years Ridgway’s use of it for the Calaveras Warbler, a new name must be provided for the latter. To that end I propose Vermivora ruficapilla ridgwayi nom. nov. to replace Vermivora ruficapilla gutturalis (Ridgway), preoccupied. 1Contribution from the California Institute of Technology. 21—Proc.

P To the late Robert Ridgway, more perhaps than to any other one man, ornithologists the world over are indebted for F the great advance in our systematic knowledge of North American birds that has marked the last fifty years. The eight published volumes of his “Birds of North and Middle America,” brought out at the culmination of his scientific | career, stand as a monument to his erudition, his sound judg- ment, his tirelessness in pursuit of truth. His treatment of many of the difficult problems encountered as his work pro- gressed will doubtless stand as the final word for many years to come. While primarily concerned with the birds found north of the Isthmus of Panama, numerous extralimital genera and species are treated incidentally. One wonders what Ridg- way’s genius could have accomplished with South American birds had he had access to the series now available for study, instead of to the wholly inadequate material on which in most cases he was forced to rely. In offering the present modest contribution to help fill this gap, the writer is well aware that ; his own efforts fall far short of the standard set by the master ( workman, but the work itself is the model he has tried to keep before him. During the past several years the growth of the bird col- lections of the Carnegie Museum, largely coming from tropical America, has resulted in bringing in good series of many species which have heretofore been little known. Among others the birds of the genus Pachysylvia have benefited, until the series ) of this group alone have reached an even six hundred specimens, 22—Proc. Bron. Soc. WasH., Vou. 42, 1929. (181) ; «+ + =o 182 Proceedings of the Biological Society of Washington. representing no less than twenty-four species and subspecies. In attempting to identify these some difficulty has been en- countered, due to the eminently unsatisfactory and out-of-date treatment accorded the group by Gadow, the latest available authority, in Volume VIII of the Catalogue of the Birds of the British Museum, and to the scattered references in the literature. The present paper has been prepared with the ob- ject of collating the synonymy and descriptions of the several forms, and bringing our general knowledge of them down to the present date. In addition to the series in the Carnegie Mu- seum, access has been had to a certain amount of material in other collections, as follows: the American Museum of Natural History, the Museum of Comparative Zoology, the United States National Museum (including the Biological Survey Col- lection), the Field Museum of Natural History, and the private collection of Mr. Donald R. Dickey of Pasadena, California. To the authorities in charge of these several collections thanks are due for such courtesies extended. I am also under obliga- tions to Dr. C. E. Hellmayr of the Field Museum for his valu- able manuscript notes on several species, kindly placed at my disposal. No effort has been made to give a full list of refer- ences to the literature, only the first citation under each name having been quoted. The names of colors are mostly from Ridgway’s ‘“‘Color Standards and Color Nomenclature.” Measurements, where given, are in millimeters, and unless otherwise stated are the average of a series of specimens. The length of the bill is that of the exposed culmen. Measure- ments of specimens of this group in the Carnegie Museum collec- tion have mostly been made by Miss Ruth Trimble. Genus Pachysylvia Bonaparte. Hylophilus (not Hylophila Hibner, 1816) Tremmincx, Pl. Col. III, livr. 29, 1822, pl. 173, fig. 1 and text (type, H. poicilotis Temminck, by desig- nation of Gray, 1840). Pachysylvia BONAPARTE, Consp. Avium, I, 1850, 309 (type, by monotypy, Sylvicola decurtata Bonaparte). The taxonomic history of this group, given in full by Sclater (Ibis, 1881, 293), need not be here repeated. His arrangement was followed by Gadow (Catalogue Birds British Museum, VIII, 1883, 305-313), since which time no comprehensive review of the genus has appeared, although no less than twenty-two additional forms have been described. It was Dr. Oberholser Todd—A Review of the Vireonine Genus Pachysylvia. 183 who first called attention to the preoccupation of Temminck’s name (Pro- ceedings Biological Society of Washington, XVI, 1903, 101). Neverthe- less the International Code would permit the use of the name, but I pre- fer to adhere to the A. O. U. Code in this regard. The diagnosis of the genus will stand in the main as given by Ridgway in his “‘ Birds of North and Middle America” (Bulletin United States National Museum, No. 50, III, 1904, 214-215). The relative length of the tail, however, varies greatly, from slightly longer than the wing in P. poicilotis to the diminu- tive dimensions found in P. minor and P. decurtata, at the other end of the series. Twenty-three species and twelve additional subspecies, two of which are here described as new, are recognized in the present review. Only one form, P. flaviventris, the type of which is unique, has not been examined in this connection. The Sylvia flaveola of Wied (Beitrage Naturgeschichte Brasilien, III, ii, 1831, 719), which has been placed in this genus, is not identifiable from the description, and the type is not extant, so that the name may be disregarded. The geographical range of the group is from southern Mexico to northern Argentina, but only one outlying species reaches the former country, while all those occurring north of Panama are obviously related to forms from the South American continent. The genus as a whole is essentially one of the Tropical Zone, but there are three species which are characteristic of the Subtropical. Much difficulty has been encountered in drawing up the following key, which is based on comparative characters observable in a series, and one form, P. flaviventris, had to be omitted from consideration.

Description.—Pileum dull antique brown, with (sometimes) a dull ee ——eEeeEeEeEeE—eEeEee Se 186 Proceedings of the Biological Society of Washington. grayish nuchal band behind; upper parts, and wings and tail externally, warbler green, the outer primaries narrowly edged with grayish white; sides of the head grayish, the ear-coverts mottled with darker color; throat dull grayish, with more or less buffy yellowish wash, which increases and deepens on the breast, and becomes almost ‘‘solid’’ dull wax yellow on the sides and flanks, leaving only the middle of the abdomen buffy white; crissum pale yellow; under wing-coverts and inner edgings of the remiges also pale yellow; bill and feet dark-colored (in skin). Measurements.—Male: wing, 57; tail, 57.5; bill, 11; tarsus, 17.2. Female: wing, 55; tail, 57; bill, 11; tarsus, 17.5. Range.—Southern Brazil (Rio de Janeiro to Santa Catharina), west- ward to Paraguay and Misiones, Argentina. Remarks.—Temminck’s figure is easily recognizable as applicable to the present form, although the coloring is none too accurate. His type was a skin in the Vienna Museum collected by Natterer at Ypanema, as we learn from Dr. Hellmayr. Other travellers have since extended its latitudinal range somewhat, and Mr. Ernest G. Holt has recently traced it to an altitude of 5900 feet on the slopes of Itatiaya. This is the only species of Pachysylvia which has the tail regularly equal to or even a little longer than the wing. Pachysylvia amaurocephala (Nordmann). Sylvia amaurocephala NORDMANN, in Erman’s Reise, Naturhist. Atlas, 1835, 14 ({[boundary between Minas Geraés and Bahia], Brazil—cf. Hellmayr, Field Mus. Zool. Ser., XII, 1929, 262). Pachysylvia amaurocephala cearensis SNETHLAGE, Journ. f. Orn., LX XIII, 1925, 266 (Sao Paulo, Serra de [biapaba, Ceard, Brazil). Description.—Pileum Brussels brown, sharply defined from the neutral gray of the nape, which passes into the dull serpentine green of the upper parts, tail, and wing-coverts; remiges externally similar but rather brighter (yellowish citrine); sides of the head dull grayish white, with indistinct paler superciliaries; throat and upper breast pale smoke gray, passing into dull pinkish buff on the abdomen and crissum; sides and flanks shaded with olive lake; under wing-coverts and inner edges of the remiges citron yellow; “‘iris brown; feet gray; bill black, the mandible light gray.” Measuremenis.—Five specimens (both sexes): wing, 52.5; tail, 48.5; bill, 10.5; tarsus, 17. Range.—Eastern Brazil, from Piauhy and Ceard to Sao Paulo. Remarks.—Dr. Hellmayr (1. c.) says that this form completely inter- grades with P. poicilotis in Sao Paulo, as shown by Natterer’s series in the Vienna Museum. There are two skins from ‘‘Bahia”’ in the series ex- amined which are brighter above and below, and might be considered as approaching the form in question. The single Sao Paulo skin of poicilotis seen, however, is perfectly typical, and moreover, I can not understand why intergradation should take place in this State when specimens from Rio de Janeiro, farher east, are also typical poicilotis. Aside from the color-differences, which are well marked, there is a difference in pro- Todd—A Review of the Vireonine Genus Pachysylvia. 187 portions, the tail being shorter than the wing in amaurocephala, but a little longer in poicilotis. So I should prefer to keep them specifically distinct for the present. But I fully agree with Dr. Hellmayr in relegating cear- ensis Snethlage to synonymy. Pachysylvia thoracica (Temminck). Hylophilus thoracicus Temminck, Pl. Col., livr. 29, 1822, pl. 173, fig. 1, and text ({Rio de Janeiro], Brazil—cf. Hellmayr, Nov. Zool., XIII, 1906, 355, and XV, 1908, 20). Description.—Upper parts in general, wings externally, and tail dull green (between warbler green and citrine); pileum and nape deep grayish olive, tinged with dull citrine, especially on the forehead; sides of the head similar but duller; throat dull grayish white, passing into wax yellow on the breast; under wing-coverts brighter (strontian yellow), and inner webs of the remiges edged with the same color; rest of the under surface white, with a light tinge of creamy buff; bill and feet dark-colored (bluish gray in life?). Measurements.—One male: wing, 59; tail, 55; bill, 12; tarsus, 19. Range.—State of Rio de Janeiro, southeastern Brazil. Remarks.—Temminck’s figure is a fairly good representation, except that the gray on the head is of too blue a shade, and his description fits the single specimen examined (No. 147,075, Collection American Museum of Natural History, La Raiz, foot of Organ Mountains, Rio de Janeiro) very well. The bill and feet are represented as dark-colored. This is im- portant, showing that this feature is of diagnostic value, and is not due to immaturity. Sclater (Ibis, 1881, 298) and Gadow (Catalogue Birds British Museum, VIII, 1883, 307) confused this species with P. pectoralis. The error was corrected by von Berlepsch and Hartert (Novitates Zoologice, IX, 1902, 11). Itis in fact unknown beyond the confines of the State of Rio de Janeiro, as shown by Dr. Hellmayr (Novitates Zoologice, XV, 1908, 20). Pachysylvia flaviventris (Cabanis). Hylophilus flaviventris Capanis, Journ. f. Orn., 1873, 64 (Monterico, Peru). Description.—‘‘Pileum and nape (abruptly defined posteriorly) light earthy brown, with a slight olivaceous tinge, caused by certain feathers being laterally edged with dull yellowish olive; back brownish olive green (hard to define); rump and upper tail-coverts light yellowish olive green, contrasting with the more brownish mantle (or upper and middle back). Lesser wing-coverts brownish like the upper back; median and greater series duller, more brownish gray, edged with greenish; remiges dusky, ex- teriorly margined with yellowish olive green, this margin passing into whitish along the apical half on the second to sixth primaries; rectrices dull olive yellowish green, brighter on the edges.

Remarks.—This species is known from the type-specimen alone. Dr. Hellmayr has kindly sent me the above detailed description and following notes, made some years ago on the specimen in question, in the Warsaw Museum. “A very peculiar species, not to be confused with any other member of the genus. It is particularly well characterized by its elongated slender bill. By possessing a distinct cap this species approaches P. pec- toralis, but has a much longer, slenderer bill, and differs furthermore, by its brownish mantle, uniform, dull olive yellowish ventral surface (except- ing the white throat), without any white on the abdomen, and brownish (instead of light gray) sides of the head, etc.”’ Pachysylvia pectoralis (Sclater).

Description.—Pileum and nape plain dull gray (near mouse gray), the sides of the head similar but paler; back, wings externally, and tail dull yellowish green (between warbler green and citrine); throat dull grayish white; breast olive yellow; under wing-coverts strontian yellow; inner webs of the remiges edged with yellowish citrine; tibiz and crissum washed with the same color; abdomen whitish with a faint buffy grayish wash; bill and feet pale (in skin). The juvenal dress is grayish above, tinged with greenish posteriorly; below whitish, with a pale yellow tinge on the flanks and crissum. Measuremenis. Aa wing, 56.5; tail, 45; bill, 12.3; tarsus, 16. Female: wing, 53.5; tail, 44.5; bill, 12; tarsus, 16. Range.—Guiana, south to the States of Matto Grosso and Goyaz, Brazil. Remarks.—This species differs from P. griseiventris in having no greenish wash on the pileum, which is uniform gray; and also in the greater extent of the yellow color below, which covers the upper abdomen as well as the breast. The abdomen is more buffy white, less grayish. Otherwise the colors are about the same in both. ee ee ee Fe See ey ee — Todd—A Review of the Vireonine Genus Pachysylvia. 189 I can find no constant differences between specimens from Brazil (States of Maranhdo and Parad) and our large series from French Guiana. Birds from British Guiana have been described by Chubb under the name abariensis, but topotypes of the latter are also the same. Even if there were a northern race it would have to bear the name applied by the Messrs. Penard in 1910, as Dr. Hellmayr points out (Field Museum Zoological Series, XII, 1929, 262). He adds that the P. araguaye of Reichenow is also indistinguishable. Gadow’s unfortunate error in the description of P. pectoralis may have been responsible for the perpetration of these synonyms. Pachysylvia sclateri (Salvin and Godman). Hylophilus sclateri SALvin and Gopman, Ibis, 1883, 205 (Mount Roraima, British Guiana). Description.—Pileum and nape deep neutral gray, the forehead and lores tinged with clay-color, the sides of the head paler gray; back dark warbler green; wings and tail deep mouse gray externally, the outer remiges edged with paler and purer gray; throat buffy white; breast washed with primuline yellow, passing into yellowish citrine on the sides and into dull whitish on the middle of the abdomen; under wing-coverts pale yellow; inner edgings of the remiges whitish; bill and feet brownish (in skin). Measurements.—Male: wing, 61; tail, 51; bill, 11.7; tarsus, 17.5. Female (one specimen): wing, 60; tail, 49; bill, 12; tarsus, 17. Range.—Mount Roraima district, British Guiana. Remarks.—The above description is based on freshly collected speci- mens in the American Museum of Natural History. A skin collected by Whitely in 1883 has faded appreciably. Some of the specimens have the wings and tail partly edged with the color of the back, instead of grayish; they are perhaps not fully mature. The crissum in some individuals is pure white, while in others it is tinged with pale yellow. This form combines the yellowish green breast-band of the thoracica- pectoralis group with the rufescent forehead of P. muscicapina, luteifrons, etc. It is obviously a Subtropical Zone representative of some lower- ranging form. Pachysylvia griseiventris griseiventris (von Berlepsch and Hartert). Hylophilus thoracicus griseiventris voN BERLEPSCH and Hartert, Nov. Zool., IX, 1902, 11 (Suapure, Caura River, Venezuela). Description.—Upper parts, wings externally, and tail dull warbler green (between warbler green and olive green); forehead the same, but crown and nape more or less extensively neutral gray; throat dull grayish white, passing into pyrite yellow on the breast; under wing-coverts and inner edges of the remiges similar but brighter; rest of the under parts white with a decided grayish shade (near pallid neutral gray); bill and feet pale (in skin). 190 Proceedings of the Biological Society of Washington. Measurements.—Male: wing, 55.5; tail, 45; bill, 18; tarsus, 17. Female: wing, 55; tail, 46; bill, 12.5; tarsus, 16. Range.—From eastern Venezuela (south of the Orinoco) and Guiana southward to the Rio Purts, Brazil. Remarks.—This bird was described as a race of P. thoracica, but after comparing our series with a specimen of the latter from southern Brazil I am confident that they represent a form specifically distinct. The pale bill and feet and grayish-tinged posterior under parts are very different from those of thoracica, in which the bill and feet are dark-colored and the posterior under parts creamy buff. The discontinuous range of thoracica and griseiventris with reference to each other is another point to be con- sidered. We have fifteen specimens from French Guiana (Tamanoir and Pied Saut), one from the north bank of the Amazon at Obidos, four from the Rio Puris (Hyutanahan, Nova Olinda, and Arim4&), and one from the upper Amazon (Sao Paulo de Olivenga). The skins from the last two regions vary among themselves to a certain extent, in the direction of emula, but some of this variation may be due to age. Pachysylvia griseiventris emula Hellmayr. Pachysylvia thoracica emula HeLuMAyR, Anz. Orn. Ges. Bayern, No. 3, 1920, 15 (Yahuarmayo, Carabaya, southeastern Peru). Subspecific characters.—Similar to P. griseiventris griseiventris, but gray color of the pileum less in extent, sometimes entirely wanting; and throat and posterior under parts more buffy, less grayishin tone. Size about the same. Range.—Tropical Zone along the eastern base of the Andes, from Co- lombia to southeastern Peru. Remarks.—This form is closely related to true P. griseiventris, of which it is the western or Andean representative, but in my opinion it is not sub- specifically related to P. thoracica, which latter has dark-colored feet and bill, and whose known range is moreover disconnected and far removed. An immature example (No. 53,506, Collection Field Museum of Natural History), however, moulting out of the juvenal dress, has dark-colored feet (by comparison) and bill, suggesting such a derivation as would be implied. Of this form I have examined four specimens, one from ‘‘ Bogota,” Colombia, one from La Pampa, Peru, and two from Rioja, Peru. Pachysylvia semicinerea semicinerea (Sclater and Salvin). | Hylophilus semicinereus ScLaTeR and Satvin, Proc. Zool. Soc. London, 1867, 570, pl. 30, fig. 2 (Para, Brazil). Description.—Above pale olive green (between olive green and dark citrine), with a neutral gray nape-band, poorly defined anteriorly; wings externally and tail like the back; under parts pallid neutral gray, the sides of the breast shaded with sulphine yellow, the abdomen medially nearly Sa ee te Todd—A Review of the Vireonine Genus Pachysylvia. 191 white, the crissum whitish or with a faint yellowish tinge; under wing- coverts and inner edgings of the remiges lemon yellow. Measurements.—Male: wing, 56.5; tail, 45; bill, 138; tarsus, 17.5. Female: wing, 55; tail, 47; bill, 12.8; tarsus, 17. Range.—Brazil, south of the Amazon, from the Rio Madeira east to the State of Maranhdao. Remarks.—Dr. Hellmayr (Novitates Zoologica, XIII, 1906, 355; XIV, 1907, 5; XV, 1908, 21) long regarded this form as a race of P. thoracica, to which I can not agree, holding that the broad colored breast-band of the latter is a good specific character. He has recently been induced to re- verse his opinion (cf. Field Museum Zoolagical Series, XII, 1929, 261), but on entirely different grounds. The amount of gray on the nape varies considerably, but there is no difference between birdsfrom Pard (Benevides), the type-locality, and the Rio Tapajéz, as he at one time thought might be the case. Birds in immature (‘“‘first winter’’) plumage, with soft skulls, are precisely like adults. Pachysylvia semicinerea viridiceps, subsp. nov. Type, No. 65,377, Collection Carnegie Museum, subadult male; Pied Saut, French Guiana, December 14, 1917; Samuel M. Klages. Subspecific characters—Similar to P. semicinerea semicinerea, but pileum and nape with less grayish tinge, sometimes almost uniform with the back; and under parts averaging paler, more whitish, with the green wash on the breast paler and less extensive. Size about the same. Range.—Southern Venezuela (Mount Duida) to French Guiana, and southward to the Amazon. Remarks.—The present form is based on a series of eleven specimens in the collection of the Carnegie Museum from the following localities: Pied Saut, French Guiana; Obidos and Manacapurt, Brazil. In addition there is a skin in the collection of the American Museum of Natural His- tory from the foot of Mount Duida, Venezuela, which I consider referable to the same form. At first glance I thought these were young birds of P. griseiventris, but upon closer comparison they appear to represent an unnamed race of P. semicinerea, differing in the more greenish, less grayish pileum, and slightly paler lower parts. In semicinerea the pileum is de- cidedly grayish, at least posteriorly, and well contrasted with the back, while in the new form the gray is duller, more overspread with green, and less contrasted with the back. Individual specimens from the two series respectively approach each other, but the series as a whole are sufficiently distinct. As nearly as I can tell, however, all but a few of the series have soft spots in the skull, indicative of immaturity, but on the other hand several examples of griseiventris are in the same condition, but are exactly like adults in coloration. Moreover, the juvenal dress of griseiventris is yellowish below (the throat and breast), while none of the present lot have any more of this color below than semicinerea, and most of them have less. The discovery of an undoubted geographical variant of P. semicinerea, coming from the same localities as P. griseiventris, of course disposes of the idea that these two are conspecific. 192 Proceedings of the Biological Society of Washington. Pachysylvia brunneiceps (Selater). Hylophilus brunneiceps ScuatEeR, Proc. Zool. Soc. London, 1866, 322 (““Ypanema”’ [error]=Rio Vaupe, Brazil—cf. von Pelzeln, Orn. Brasil- iens, 1868, 70, note, and Sclater, Ibis, 1881, 306). Description.—Pileum dull sepia with a wash of citrine, passing into dull warbler green on the back, tail, and wings externally; sides of the head dull brownish, paler than the pileum; throat and upper breast soiled white, washed with deep olive buff; rest of the under parts white with a grayish shade, the sides and flanks washed with yellowish citrine, the crissum with pale yellowish green; under wing-coverts and inner edges of the remiges amber yellow; bill and feet pale brown (in skin). Measurements.—One male: wing, 51; tail, 41; bill, 13.5; tarsus, 16.5. Range.—Northern Brazil (Rio Negro) to southern Venezuela (and east to Guiana?). : Remarks.—In describing this species Sclater attributed it to southern Brazil, having in some way mixed up his specimens and transposed his notes, as pointed out by von Pelzeln (1. c.) and later corrected by Sclater himself. I have seen but one example (No. 121,032, Collection American Museum of Natural History), from San Fernando, upper Orinoco, Venez- uela; it fits Sclater’s figure (Ibis, 1881, pl. 11, fig. 1) very exactly. I doubt if it occurs in Guiana—French Guiana, at any rate, where Mr. Klages’ researches have failed to discover it. It probably occupies the little known region north of the Amazon, along the Rio Madeira and northward to the Orinoco. South of the Amazon it is replaced by P. inornata Snethlage. Pachysylvia luteifrons (Sclater). Hylophilus luteifrons Sctatzr, Ibis, 1881, 308 (Bartica Grove, British Guiana). Hylophilus surinamensis PENARD and PENARD, Vog. Guyana, II, 1910, 538 (Surinam). Description.—Above dark citrine, the pileum a little darker, more oli- vaceous, the remiges externally more brownish (orange citrine), the tail still deeper (medal bronze); forehead and supraloral region tinged with dull buffy yellow (but not conspicuously); under parts washed with prim- rose yellow, the breast usually more buffy (near dark olive buff), the crissum deep colonial buff, as also are the under wing-coverts and inner edgings of the remiges. Measurements.—Male: wing, 57; tail, 41; bill, 12.5; tarsus, 15. Female: wing, 56; tail, 39; bill, 12; tarsus, 15. Range.—Guiana, south to the Amazon River, Brazil. Remarks.—Little is on record concerning the present species, which was at first supposed to be confined to British Guiana. It was found in French Guiana by Mr. George K. Cherrie (cf. von Berlepsch, Novitates Zoologicer, XV, 1908, 109), and Mr. 8. M. Klages has also sent a good series from that country to the Carnegie Museum. The same collector took a single specimen at Obidos, and Miss Snethlage records it from St. Antonio da Todd—A Review of the Vireonine Genus Pachysylvia. 193 Cachoeira, on the Rio Jary, showing that its range reaches to the north bank of the Amazon. Pachysylvia rubrifrons rubrifrons (Sclater and Salvin). Hylophilus rubrifrons ScLATER and SALvIin, Proc. Zool. Soc. London, 1867, 569, pl. 30, fig. 1 ([Pard ?], lower Amazon River, Brazil). Description.—Upper parts dark citrine, the pileum sometimes a little more olivaceous, in but slight contrast; wings externally like the back, the wing-coverts with slight rufescent edgings; tail brown (between Prout’s brown and Brussels brown); forehead and supraloral region antique brown; sides of the head in general, and throat and breast, honey yellow, passing into ecru olive on the abdomen and crissum; under wing-coverts reed yellow, and inner edgings of the remiges buffy yellow (near honey yellow). Measurements.—Male (three specimens): wing, 56; tail, 39; bill, 12.5; tarsus, 15. Female (two specimens): wing, 56; tail, 38.5; bill, 13; tarsus, — 16. Range.—Para region of northeastern Brazil. Remarks.—Dr. Hellmayr (Novitates Zoologice, XVII, 1910, 267) says that the type of this species must have come from the Rio Negro. Reason- ing by analogy, it would seem unlikely that a form such as rubrifrons, which is replaced farther west on the same bank of the Amazon by a different race, would reappear unchanged on the opposite bank. The only speci- mens with definite localities attached all come from the vicinity of Pard, and in my opinion it is entirely likely that the type-specimen actually came from this place too, where Wailace also collected for a time. An error in labeling may easily have occurred. Dr. Hellmayr’s description of the type (an immature bird) points to its being the same as the series from Benevides studied in this connection, the specimens from the Rio Madeira with which he compared it doubtless belonging to lutescens. P. rubri- frons appears to be represented on the north bank of the Amazon by P. luteifrons, as already pointed out. The range of the typical form is prob- ably limited to the westward by either the Rio Tocantins or Rio Xingu. Pachysylvia rubrifrons lutescens Snethlage. Pachysylvia rubrifrons lutescens SNETHLAGE, Orn. Monatsb., XXII, 1914, 43 (Boim, Rio Tapajéz, Brazil). Subspecific characters.—Similar to P. rubrifrons rubrifrons, but upper parts purer green (near citrine); tail paler brown (Dresden brown); and under parts more uniform, washed with primrose yellow. Size about the same. Range.—Northern Brazil, south of the Amazon, from the Rio Xingti west to the Rio Madeira. Remarks.—This form was described as new on the assumption that birds from Para belong to the typical rubrifrons. It differs very decidedly from the latter in being brighter, more yellowish green below, as well as above. Some of our specimens from Miritituba, however, are darker 194 Proceedings of the Biological Society of Washington. above and more buffy yellow. ‘Twenty-six specimens in all have been ex- amined in this connection, all from various localities on the Rio Tapajéz (Colonia do Mojuy, Villa Braga, Miritituba, and Apacy). Pachysylvia ochraceiceps viridior, subsp. nov. Type, No. 79,588, Collection Carnegie Museum, adult male; Rio Surutu, Bolivia, September 23, 1917; José Steinbach. Subspecific characters.—Similar to P. ochraceiceps ferrugineifrons, but brighter, purer yellowish green (between citrine and dark citrine) above, with less of the brownish suffusion usually so conspicuous in the latter; forehead paler russet (orange citrine rather than antique brown); tail paler and less brownish. Size about the same. Range.—Santa Cruz region of Bolivia to southeastern Peru, in the Tropical Zone. | Remarks.—The characters above specified, while subject to individual variation in the series of sixteen specimens examined, are sufficiently con- stant to require the separation of the Bolivian birds under the name here proposed. Under this name | would place also the specimens from south- eastern Peru referred to by Dr. Chapman (Bulletin American Museum of Natural History, LV, 1926, 589). In juvenal dress (No. 50,767, Collection Carnegie Museum) this form is dull buffy citrine above, almost uniform, and soiled white below, shaded with buffy, the crissum pale yellow. Pachysylvia ochraceiceps ferrugineifrons (Selater). Hylophilus ferrugineifrons Scuater, Proc. Zool. Soe. Londen 1862, 110 ({‘‘ Bogoté”’], Colombia). Description.—Forehead dull antique brown, passing into dull dark citrine on the crown and upper parts, including the wings externally; tail dull medal bronze; under parts in general dull whitish, more or less heavily washed with olive lake or ecru olive, the throat paler, more whitish; under wing-coverts and inner edgings of the remiges reed yellow. Measurements.—Male: wing, 58.5; tail, 42; bill, 13.3; tarsus, 15.3. Female: wing, 55.5; tail, 40.5; bill, 13; tarsus, 15. Range.—Tropical Zone of Colombia and Ecuador (east of the Andes), east to the Guiana frontier of Venezuela, and south to the Rio Puris, Brazil. Remarks.—The above description is based on a skin from Tonantins, Brazil, the place nearest to the type-locality from which a specimen is at present available. It corresponds closely to Sclater’s figure of the species in the Ibis, 1881, pl. 11, fig. 2. In a series from eastern Venezuela (Rio Caura and Rio Yuruan) the iris is variously marked as ‘‘brown,” “‘white,”’ ‘‘oray,” and ‘‘grayish white’’; the bill as “blackish, pale below”; and the feet as ‘‘pale leaden blue,” etc. They are exactly the same as another series from the Rio Purts, Brazil, and show a decided brownish cast above as compared with birds from Bolivia (viridior). We have specimens from Rio Yuruan, Venezuela, and Manacapurti and Caviana, on the middle Todd—A Review of the Vireonine Genus Pachysyluia. 195 Amazon River, Brazil, which localities probably mark the extreme eastern limits of the range of the species. Dr. Chapman records it from eastern Ecuador, so that it evidently occupies an immense area in the drainage systems of the Amazon and Orinoco Rivers, right up to the eastern base of the Andes. West of this range it is replaced by the next form. After study and comparison I have come to believe with Dr. Chapman (Bulletin American Museum of Natural History, LV, 1926, 589) that ferrugineifrons should be considered as conspecific with ochraceiceps and bulunensis. Pachysylvia ochraceiceps bulunensis (Hartert). Hylophilus bulunensis Hartert, Nov. Zool., 1X, 1902, 617 (Bulin, Ecua- dor). Subspecific characters.—Similar to P. ochraceiceps nelsoni, but still more greenish, less brownish; back and wing-coverts almost uniform dark citrine; and lower parts strongly washed with olive yellow, the throat a little duller, grayish white. Measurements.—Male (two specimens): wing, 58.5; tail, 40; bill, 12.7; tarsus, 16.7. Female: wing, 55; tail, 41; bill, 13; tarsus, 16.3. Range.—Tropical Zone, Colombian-Pacific Fauna, from eastern Panama to western Ecuador. Remarks.—This form must stand as a subspecies of P. ochraceiceps, all of its characters being merely a further development of those of P. ochracei- ceps nelsoni, which connects the two extremes systematically as well as geographically. Dr. Chapman did not find it in Colombia, but we have four specimens from the Chocé region (Potedo and Malagita). These are slightly more greenish above than skins from eastern Panama (Mount Pirri and Cana), but are without question the same form. On the other hand, this form is so exactly intermediate in its characters between nelsoni and ochraceiceps on the one hand and ferrugineifrons and viridior on the other that I have no choice but to consider them all conspecies, in spite of the fact of their discontinuous distribution by reason of the interposition of the Andean chain. Pachysylvia ochraceiceps nelsoni, nom. nov. Pachysylvia ochraceiceps brevipennis (not Helinai brevipennis Giraud) NeEtson, Smithsonian Misc. Coll., LVI, No. 22, 1911, 1 (Lion Hill, Panama). Subspecific characters.—Similar to P. ochraceiceps ochraceiceps, but upper parts and wings externally with less brownish wash, more greenish; and under parts also slightly more greenish, the breast with less buffy shading. Measurements.—One male (?) (the type): wing, 54; tail, 38; bill, 13; tarsus, 17. One female (?): wing, 58; tail, 43; bill, 13; tarsus, 17.5. Range.—Isthmus of Panama. Remarks.—I strongly suspect that both the above examples are wrongly sexed. If so, then the difference in size to which the describer alludes is of 196 Proceedings of the Biological Society of Washington. little importance. After seeing these two specimens, I would recognize the form they represent as a valid one, standing as an intermediate be- tween ochraceiceps and bulunensis. But because of Helinai brevipennis Giraud, Annals Lyceum Natural History of New York, V, 1852, 40, pl. 3, fig. 1, which is a synonym of Pachysylvia decurtata, a new name will be necessary in this case, which I supply above, in honor of the original de- scriber. Pachysylvia ochraceiceps ochraceiceps (Sclater). Hylophilus ochraceiceps ScuaTER, Proc. Zool. Soc. London, 1859, 375 (Playa Vicente, Oaxaca, Mexico). Pachysylvia ochraceiceps pallidipectus RipaGway, Bull. U.S. Nat. Mus., No. 50, III, 1904, 219 (Angostura, Costa Rica). Description.—Pileum dull yellowish brown (near old gold), passing into Dresden brown on the back, wing-coverts, and tail, the nape more oli- vaceous, and the rump washed with yellowish citrine; primaries margined externally with old gold, passing into Dresden brown on the secondaries, the primary-coverts olive; supraloral line olive ocher; sides of the head and upper throat dull grayish with a wash of olive; rest of the lower parts dull buffy yellow, the breast and sides more or less strongly washed with olive ocher or olive lake, the flanks more with yellowish citrine; under wing- coverts pale lemon yellow, and inner webs of the remiges edged with deep colonial buff; ‘‘iris gray; bill horn brown above, paler below; feet flesh- © color.” ! A juvenal example is almost uniform Dresden brown above, with whitish throat, and the rest of the under parts washed with clay-color. Measurements.—Male: wing, 59; tail, 44; bill, 13.2; tarsus, 16.5. Female: wing, 57; tail, 44; bill, 13; tarsus, 16.5. Range.—Southern Mexico (Tropical Zone) to western Panama. Remarks.—There is so much individual variation in the series examined, considered as a whole, that I fail to see how pallidipectus can possibly be maintained. Every character ascribed to this supposed form, tested by this series, fails. Pachysylvia insularis (Selater). Hylophilus insularis ScuaTER, Proc. Zool. Soc. London, 1861, 128 (Tobago). Hylophilus pallidifrons Datmas, Mém. Soc. Zool. France, XIII, 1900, 135 (Tobago). Description.— Above varying from deep grayish olive to citrine, grayer on the head, more greenish on the rump, wings externally, and tail; supra- loral streak and lower eyelid pale buffy whitish; under parts deep olive buff, almost uniform, the flanks sometimes with a greenish wash, and the crissum sometimes tinged with yellow; under wing-coverts and inner edgings of the remiges pale yellow (amber yellow to naphthalene yellow); bill dark above, pale below; feet pale brown (in skin). Measurements.—Male: wing, 61; tail, 47; bill, 12.7; tarsus, 19. Female: wing, 61; tail, 47; bill, 13; tarsus, 18.5. Todd—A Review of the Vireonine Genus Pachysyla. 197 Range.—lsland of Tobago. Remarks.—Dr. Hellmayr writes that he has compared the type of H. “nallidifrons’’ (now in the Tring Museum) with that of H. insularis, and found them identical. The type-specimen of the latter is slightly immature. The description of “‘pallidifrons’’ fits the series examined very well, except for the measurement of the tail, 57 mm., which is probably an error for 47 mm. The variation in the color of the upper parts is astonishing, but may be due in part to post-mortem changes in the skins. The large size, heavy bill, and grayish coloration serve to separate this species from P. flavipes acuticauda, its nearest relative on the mainland. Curiously enough, P. flavipes has no representative on Trinidad, and P. insularis is an isolated and well differentiated form. Pachysylvia olivacea (von Tschudi). Hylophilus olivaceus von Tscuun1, Arch. f. Naturg., 1844, 284 ([eastern slope of the Andes], Peru). Description.—Above dull yellowish olive, duller and more brownish on the pileum, the wing- and tail-edgings a little lighter; below buffy whitish, the throat, breast, and sides heavily shaded with olive yellow, and the crissum with amber yellow; under wing-coverts and inner edgings of the primaries massicot yellow; bill and feet pale brown (in skin). Measurements.—One male: wing, 60; tail, 48; bill, 11.5; tarsus, 17.5. One female: wing, 56; tail, 48; bill, 11.5; tarsus, 18. Range.—Subtropical Zone, central Peru to eastern Ecuador. Remarks.—This species, of which I have seen but two specimens (from eastern Ecuador), is hard to place, but gives the impression of being related to P. flavipes acuticauda, from which it differs in its relatively longer tail, and more olive greenish or yellowish under parts. It appears to be a Subtropical Zone species. Very few specimens are known at the present time. . Pachysylvia flavipes acuticauda (Lawrence). Hylophilus acuticaudus LAWRENCE, Proc. Acad. Nat. Sci. Philadelphia, 1865, 37 (Venezuela). Hylophilus griseipes Ricumonp, Proc. U. 8. Nat. Mus., VIII, 1896, 687 (Margarita Island, Venezuela). Subspecific characters.—Similar to P. flavipes flavipes, but general colora- tion duller; upper parts duller citrine; under surface deep olive buff, paler posteriorly, with little or no yellow tinge. Measurements.—Male: wing, 56; tail, 44; bill, 12; tarsus, 17.5. Female: wing, 53; tail, 43; bill, 11.7; tarsus, 17.5. Range.—Venezuela, south (at least) to the Orinoco River and east to the Guiana frontier. _ Remarks.—While Ridgway (Bulletin United States National Museum No. 50, III, 1904, 216, note) would keep this form a distinct species, von 198 Proceedings of the Biological Society of Washington. Berlepsch and Hartert (Novitates Zoologice, IX, 1902, 12) reduce it to a subspecies of P. flavipes—rightly so, as I believe. It is much more buffy - below than true flavipes, lacking the yellow tinge present in most speci- mens of that form, at least in fresh plumage. The supposed difference in the color of the feet apparently does not hold, judging from the labels; both forms vary in this respect, but do not differ from each other. In juvenal dress (No. 34,042, Collection Carnegie Museum) the under parts are white, shaded anteriorly and laterally with buffy; the pileum is ashy brown; and the bill is blackish. Intergradation between this form and true flavipes takes nldcet in western Venezuela, in the Maracaibo basin. The southern range of acuticauda remains to be worked out. I can find no records from Guiana, but speci- mens in the Carnegie Museum bring it close to the borders of that country. With eight specimens from Margarita Island before me (including the type of H. “‘grisetpes’’ Richmond), I can find no sufficient grounds for separating them from mainland specimens of acuticauda. Dr. Richmond does not mention the latter at all; he compared his skins from that island directly with flavipes from Colombia, from which they of course differ. just as he says. So “‘grisezjzes’’ falls as a synonym of acuticauda. Lawrence’s type-specimen no doubt came from the coast region of northern Venezuela. In order to get a definite starting-point I hereby propose to fix the type-locality as Puerto La Cruz, State of Carabobo, Venezuela. Pachysylvia flavipes flavipes (Lafresnaye). Hylophilus flavipes LAFRESNAYE, Rev. Zool., 1845, 342 (“ Bogota,” Col- ombia). Description.—Above dark citrine, duller on the pileum, brighter on the rump and wings externally; tail similar; a pale supraloral streak; sides of the head, and breast and throat, dull buffy yellow, brightening into deep colonial buff on the abdomen and crissum; under wing-coverts amber yellow, and inner webs of the remiges citron yellow; ‘iris straw yellow; bill blackish horn, flesh-color below; feet flesh-color” (Carriker). Measurements.—Male: wing, 57; tail, 46; bill, 12; tarsus, 17. Female: wing, 55; tail, 45.5; bill, 11.7; tarsus, 17. Range.—Tropical Zone of Colombia. Remarks.—The above description is based on the more yellowish ex- treme examples. There is a great deal of variation in color in the series examined, due partly to season and age, and partly to individual dif- ferences. The feet are marked variously “bluish flesh-color,” ‘pale purplish flesh-color,” ‘‘dusky flesh-color,” and even ‘pale leaden blue.” As might be expected, specimens from the eastern base of the Eastern Andes vary more in the direction of acuticauda, and moreover are some- what larger than the average bird of the region of the Rio Sinu, where this form appears to reach its greatest degree oi differentiation, and from which the most brightly colored examples in the main seem to come. It is thus unfortunate that ‘‘Bogota’’ remains the type-locality for this form. Of Todd—A Review of the Vireonine Genus Pachysylvia. 199 course it does not occur so high up as that, but only at the foot of the moun- tains. Specimens from Villavicencio should doubtless be considered topo- typical. Pachysylvia viridiflava (Lawrence). Hylophilus viridiflavus LAwrEeNncE, Ann. Lyc. Nat. Hist. New York, VII, 1861, 324 ({Lion Hill ?], Panama Railroad, Panama). Description.—Upper parts in general (including wings externally and tail) warbler green, the pileum duller (near citrine); supraloral streak dull whitish; sides of the head dull brownish gray; under parts (near) amber yellow, the throat paler, more grayish, and the breast shaded with olive lake; under wing-coverts and inner edgings of the remiges amber yellow; “iris straw-color; feet plumbeous; bill light horn-color above, flesh-color below” (Carriker). Younger birds may readily be told by their black bills; the iris is marked as “‘gray”’ in all such. Measurements.—Two males: wing, 57, 60; tail, 44, 46; bill, 12, 12.5; tarsus, 18, 18.5. Two females: wing, 56, 56; tail, 47, 48; bill, 12, 12.5; tarsus, 17.5, 18.5. Range.—Panama and southwestern Costa Rica (Tropical Zone). Remarks.—The nearest known ally of this form is P. flavipes flavipes of Colombia, than which it is much more brightly colored. There appears to be a break in the distribution of the forms, however, in eastern Panama, ‘ where neither has yet been found, and this circumstance, taken in connec- tion with the degree of difference between them, suffices to justify the recog- nition of viridiflava as a distinct species. In southwestern Costa Rica, according to Mr. Carriker (Annals Carnegie Museum, VI, 1910, 777) it ranges from sea-level up to about 2000 feet. Pachysylvia aurantiifrons aurantiifrons (Lawrence). Hylophilus aurantiifrons Lawrence, Ann. Lyc. Nat. Hist. New York, VII, 1862, 324 ({Lion Hill ?], Panama Railroad, Panama). Descripiion.—Pileum buffy brown, the forehead strongly tinged with olive ocher or isabella color, the sides of the head paler and more buffy; back, wings externally, and tail yellowish citrine; throat and breast dull whitish with more or less of a buffy wash; the rest of the under parts washed with barium yellow, deepest and purest on the flanks and crissum; under wing-coverts and inner edgings of the remiges citron yellow to barium yellow; “iris brown; feet plumbeous; bill dusky horn, flesh-color below.” Measurements.—Male: wing, 56; tail, 44; bill, 13; tarsus, 16.5. Female: wing, 54; tail, 43; bill, 12.7; tarsus, 16. Range.—Caribbean coast region of Colombia, westward to the Isthmus of Panama. Remarks.—The restricted range of this form is a marked feature. It is not known to enter the Magdalena and Cauca Valleys, or the Pacific coast region of Colombia. 200 Proceedings of the Biological Society of Washington. Pachysylvia aurantiifrons saturata Hellmayr. Pachysylvia aurantiifrons saturata Hetimayr, Nov. Zool., XIII, 1906, 12 (Caparo, Trinidad). Subspecific characters.—Similar to P. aurantiifrons aurantifrons, but under parts more brightly colored, with more buffy or ochraceous wash on the chest. Measurements.—Male: wing, 56; tail, 45; bill, 13; tarsus, 16.3. Female: wing, 53; tail, 43; bill, 12.5; tarsus, 16.5. Range.—Caribbean coast region of Venezuela, eastward to Trinidad. Also in the interior of Colombia, east of the Eastern Andes. Remarks.—Selected individual specimens of the series at hand are quite indistinguishable from the average example of true aurantiifrons, but the respective series are separable by the difference in general coloration, the present form being more richly colored—more suffused with yellow, with the buffy shade on the breast more in evidence, especially in birds in freshly assumed plumage, like those from Trinidad shot in August. Speci- mens from the Carabobo region of Venezuela average less brightly colored than those from Trinidad. Birds from the Maracaibo region, on the other hand, are richly colored, although mostly collected in early May, and rather worn. Ridgway (Bulletin United States National Museum, No. 50, III, 1904, 215) was the first to distinguish this race, but confused it with P. hypox- antha, which is another bird entirely, and it remained for Dr. Hellmavr to give it the name under which it now passes. A single specimen (No. 60,643, Collection Carnegie Museum) from Palmar, Colombia, at the eastern foot of the Eastern Andes, which could be referred to aurantwifrons as easily as to saturata, shows that the species is not as strictly confined to the coast as has been supposed. Further light on its range in this part of the country will be awaited with interest. Pachysylvia hypoxantha albigula Chapman. Pachysylvia fuscicapilla albigula CHapMAaN, Am. Mus. Nov., No. 18, 1921, 11 (Sta. Julia, Rio Iriri, Brazil). Subspecific characters.—Similar to P. hypoxantha hypoxantha, but throat paler, more grayish white, less buffy; rest of the under parts richer and purer yellow (pale lemon yellow); and upper parts more richly colored (citrine instead of buffy olive). Measurements.—Three males: wing, 60; tail, 45; bill, 14; tarsus, 15.5. Four females: wing, 56; tail, 42; bill, 13; tarsus, 15. Range.—Brazil, south of the Amazon, from the Rio Xingu to the Rio Purits. Remarks.—The type-specimen I have not seen, but eight specimens from the Rio Purts (Hyutanahan, Nova Olinda, and Arima) and one from Caviana (on the south bank of the Amazon, opposite Manacapurt) differ from two skins from Tonantins, presumably representing true hypoxantha, as above said. It will be noted that while Dr. Chapman describes the Todd—A Review of the Vireonine Genus Pachysylvia. 201 under parts as “‘paler and less uniform than in fuscicapilla”’ (i. e., hypox- antha), I find the opposite to be the case. So there is a possibility that we are dealing here with a different race from the one he has described. Pachysylvia hypoxantha hypoxantha (von Pelzeln). Hylophilus hypoxanthus von PELZELN, Orn. Brasiliens, ii, 1868, 71, 136 (Rio Iganna and Rio Vaupé, Rio Negro, Brazil). Hylophilus fuscicapillus ScLATER and Satvin, Proc. Zool. Soc. London, 1880, 155 (‘‘Sarayacu,” Ecuador). Description.—Pileum dull olive brown, passing into the buffy olive of the back; wings externally and tail somewhat brighter (yellowish olive); sides of the head pale buffy brown, the eyelids slightly paler; throat dull buffy whitish; rest of the under parts (including under wing-coverts) pale yellow (barium yellow), the breast with a slight buffy wash; inner webs of the remiges edged with pale dull yellow, as also are the inner webs of the rectrices. _ Measurements.—One male: wing, 60; tail, 46; bill, 12; tarsus, 16. Two females: wing, 56; tail, 41; bill, 12.5; tarsus, 15. Range.—Northwestern Brazil, north of the Amazon, east to the mouth of the Rio Negro, and west to eastern Ecuador. Remarks.—Two females from Tonantins, Rio Solimoés, in the Carnegie Museum collection, answer pretty well to Sclater’s description and figure of Hylophilus fuscicapillus in the Ibis, 1881, 303, pl. 10, fig. 2, the throat, however, not being yellow as in the figure, but dull buffy or soiled whitish. Dr. Hellmayr writes me as follows: “P. fuscicapilla=P. hypoxantha. I have compared a bird from Pebas, Peru, with the types in the British Museum, and later with von Pelzeln’s examples, and could not discover any difference. So their identity is well established.” This is what we would expect in view of the relatively close positions of the respective type- localities. The species is a near relative of P. aurantiifrons. A male example from Manacapurt (No. 98,651, Collection Carnegie Museum) greatly extends the known range of this form. It differs from the Tonantins skins in its rather darker, duller coloration, and may possibly represent a different race. ’ Pachysylvia semibrunnea (Lafresnaye). Hylophilus semibrunneus LAFRESNAYE, Rev. Zool., 1845, 341 (‘‘ Bogotd,”’ Colombia). Pachysylvia semibrunnea leucogastra CHAPMAN, Am. Mus. Nov. No. 1438, 1924, 1 (below San José de Sumaco, eastern Ecuador). Description.—Pileum and nape Brussels brown, this color spreading over the sides of the neck as far as the ear-coverts, and sometimes over the back also; upper parts in general, and wings and tail externally, dull green (near serpentine green), the wing-coverts and primaries with slight paler edgings, and the tail also with slight yellowish internal edgings; lores, slight eye- 202 Proceedings of the Biological Society of Washington. brow, subocular region, and throat soiled whitish; under parts dull whitish, tinged with buffy rufous on the sides of the breast and with pale greenish yellow on the sides and flanks; crissum and under wing-coverts barium yellow, and inner webs of the secondaries edged with the same color, becoming whitish on the primaries; ‘“‘iris brown; feet leaden blue; bill blackish above, flesh-color below” (Carriker). Measurements.—Male: wing, 62.5; tail, 50.5; bill, 13.5; tarsus, 16.7. Female: wing, 61.7; tail, 50; bill, 13.3; tarsus, 16.7. Range.—Subtropical Zone of the Nndes of Colombia and of eastern — Ecuador. Remarks.—A topotype of ‘‘lewcogastra’’ from eastern Ecuador can be closely matched by certain examples of true semibrunnea. In the light of our fine series (21 skins) from Colombia, the characters on which this supposed subspecies are based prove to be individual rather than geo- graphical. The amount of brown wash on the back is a variable feature. P. semibrunnea is a Subtropical Zone species, belonging to the aurantit- frons-hypoxantha group, of one of which it is probably a derivative. Pachysylvia inornata Snethlage. Pachysylvia ee, SNETHLAGE, Orn. Monatsber. . XXVIT, 1914, 43 (Cametd, Rio Tocantins, Brazil). Description.—Pileum dull brown (between sepia and snuff brown), the -upper back paler and more greenish (dull orange citrine), and the lower back, tail, and wings externally warbler green, without any brownish wash; sides of the head like the pileum, but paler, with a poorly defined pale orbital ring; throat and upper breast pale olive gray, and rest of the under parts similar, the breast, sides, and flanks more or less strongly washed with yellowish citrine, the crissum citron yellow; under wing-coverts and inner edgings of the innermost secondaries citron yellow; rest of the remiges edged internally with naphthalene yellow. A bird in juvenal dress (No. 74,383, Collection Carnegie Museum) differs in having the pileum and back rusty buff, and the lower surface much duller. Measurements.—Male: wing, 59; tail, 47; bill, 13; tarsus, 16. Female: wing, 58; tail, 46; bill, 13; tarsus, 16.5. Range.—Brazil, south of the Amazon, from the Rio Tapajéz east to the Rio Tocantins. Remarks.—This form differs from P. brunneiceps in its larger size, more decidedly brownish upper parts, grayish (instead of pale brownish) throat and breast, and greenish-suffused lower breast and abdomen. ‘The yellow of the remiges is also paler (except that on the inner secondaries). I would keep the two specifically distinct, and while Dr. Hellmayr does not agree to this disposition, he may be quite right in insisting on the close relation- ship of the two forms in question. For the present, however, I am sug- - gesting a relationship to the group represented by P. aurantiifrons, P. hypoxantha, etc., as shown by the key to the species (antea). Twenty-one specimens have been examined in this connection, all from the Rio Tapajéz. Todd—A Review of the Vireonine Genus Pachysyluia. 203 Pachysylvia muscicapina muscicapina (Sclater and Salvin).

Description.—Pileum and nape neutral gray, the superciliaries and sides of the head buffy rufous in abrupt contrast; upper parts, wings externally, and tail bright serpentine green; under parts white, the throat and breast washed with rufous buff, the sides of the breast with dull greenish, and the abdomen with grayish; crissum and under wing-coverts citron yellow. Measurements.—Male: wing, 60; tail, 46; bill, 14.5; tarsus, 15.5. Female: wing, 56; tail, 43; bill, 13.5; tarsus, 15.

Remarks.—Venezuelan specimens closely resemble those from French - Quiana, the type-locality, and birds from Obidos, on the north bank of the Amazon, are also the same. On the south bank of that stream the species is represented by the next form. P.muscicapina is a rather isolated species - genetically, without any very close allies. Pachysylvia muscicapina griseifrons Snethlage. Pachysylvia musicicapina griseifrons SNETHLAGE, Orn. Monatsber., XV, 1907, 160 (Villa Braga, Rio Tapajéz, Brazil). Subspecific characters—Similar to P. muscicapina muscicapina, but upper parts slightly brighter green; sides of the head, superciliaries, etc., deeper buffy rufous; and throat and breast more strongly suffused with the same color. The gray of the pileum continues over the forehead as a pure color, instead of being tinged with buffy, as usual in the typical race. Size about the same. Range.—From the Rio Tapajéz, west to (probably) the Rio Madeira, Brazil. Remarks.—A series of seventeen specimens from the type-locality, and one more from Apacy, bear out Dr. Hellmayr’s remarks (Novitates Zoo- logice, XVII, 1910, 268) on the characters of this race. It is evidently confined to the region south of the Amazon, between the Madeira and Ta- paj6z Rivers. Pachysylvia minor minor (von Berlepsch and Taczanowski). Hylophilus minor von BreruEepscH and TaczANnowsk1, Proc. Zool. Soc. London, 1883, 542 (Chimbo, Ecuador). Description—Above warbler green, the pileum and wings externally darker (near olive green), the outer primaries edged with pale greenish white; tail still duller olive greenish; lores, sides of the head, and throat pallid neutral gray; rest of the under parts white with a pale buffy tinge, the sides of the breast, the flanks, and the crissum shaded with strontian yellow; under wing-coverts and inner edgings of the primaries pale buffy yellow; bill and feet pale brown (in skin). 204 Proceedings of the Biological Society of Washington. Measurements.—Two males: wing, 54, 56; tail, 37, 41; bill, 12, 13.5; tarsus, 18, 18.5. One female: wing, 52; tail, 36; bill, 12.5; tarsus, 17.5. Range.—Tropical Zone of western Ecuador. - Remarks.—This was described by von Berlepsch and Taczanowski from three specimens collected at Chimbo by Stolzmann, and has since been taken by other collectors in various localities in this general region (cf. Chapman, Bulletin American Museum of Natural History, LV, 1926, 590). With P. decurtata of Central America, it belongs to a group charac- terized by small size and a relatively short tail, and standing thus at the opposite end of the series from P. poicilotis. Pachysylvia minor darienensis Griscom. Pachysylvia minor darienensis Griscom, Am. Mus. Nov. No. 282, 1927, 7 (Cape Garachiné, eastern Panama). Subspecific characters.—Similar in size and general coloration to P. minor minor, but under parts not so brightly colored, the greenish yellow of the sides and flanks paler and more restricted. Range.—Tropical Zone of Colombia (Magdalena Valley and Pacific coast district), northward to eastern Panama. Remarks.—Dr. Chapman, in recording the heretofore only known specimen of P. minor from Colombia (Bulletin American Museum of Natural History, XXXVI, 1917, 541), commented on the differences it showed in comparison with Ecuador skins. We have four examples from the Chocé region of western Colombia (Andagoya, Malagita, and Cordoba) in the collection of the Carnegie Museum, and also two from El Tambor, in the valley of the Rio Lebrija, a tributary of the Magdalena. These have been compared with the Los Cisneros specimen cited by Dr. Chap- man, and found to be identical. They also agree well with a skin from Mt. Sapo, and with a topotype of darienensis from Cape Garachiné. This indicates that this pale race of minor is the one inhabiting Colombia as well as eastern Panama. According to Mr. Griscom it lives in the tops of the tallest trees, and is consequently very difficult to collect. In our two skins from El Tambor the iris is marked as ‘‘brown; feet pale leaden blue; bill black, bluish flesh below” (Carriker). Pachysylvia decurtata (Bonaparte).

Range.——Isthmus of Panama northward through Central America to Vera Cruz, Mexico, in the Tropical Zone. Remarks.—This is one of the few species of Pachysylvia which has suffered from too many names. Ridgway suspected the existence of a small southern race, and very recently Mr. Bangs (Bulletin Museum Compara- tive Zoology, LX VII, 1927, 483) has agreed to recognize such a race under Lawrence’s name pusilla. Messrs. Dickey and Van Rossem have also named a supposed pale Pacific coast race. With some of their skins before me, and a series from western Nicaragua called by the same name, also a good series from Mexico and Costa Rica, my finding is that the differences alleged to exist between decurtata, ‘‘pusilla,”’ and ‘‘pallida”’ are too slight to recognize by name. Pachysylvia decurtata is the Central American representative of P. minor. In its pattern of coloration it bears a remarkable resemblance to the Tennessee Warbler, Vermivora peregrina. Vol. 42, pp. 207-208 August 17, 1929 PROCEEDINC* OF THE BIOLOGICAL SOCIETY OF WASHIN A NEW SILENE FROM THE UMPQUA NATIONAL FOREST. BY IVAR TIDESTROM AND W. A. DAYTON. In 1924 Grazing Examiner Douglas C. Ingram of the U. S. Forest Service made a collection of forty-one plants on the Umpqua National Forest in southwestern Oregon. Among these was his specimen No. 1489, Forest Service serial No. 51202, the very showy characters of which at once gave it distinction. This plant (plate VIII) was collected on Mt. Nebo, near Roseburg, Douglas County, at 1,200 feet (400 meters), on a south slope, open grass-browse type; shallow, rocky red clay loam of basaltic formation. Mr. Ingram noted that the species was occasional in this type, did not appear to be grazed by livestock and was associated, among others, with Agoseris elata, Calochortus elegans, Festuca rubra, Phacelia heterophylla and Poa sandbergit. It is obviously closely related to Silene hookeri A. Gray, but differs in its much larger and more erect habit, different root system, showier flowers of a different color, more acuminate calyx lobes, and long-stipitate ovary. The diagnosis follows: Silene ingrami, sp. nov. Perennial with a slender stramineous rhizome. Stem apparently soli- tary, slender, striate, simple or branched, 20 to 32 cm. high, with an indu- ment of short crisp white hairs, sometimes slightly flocculose, the lower part usually purplish. Foliage somewhat grayish green, the leaves white- crisp-hairy especially on the margins and on the midrib below; lowest pair of leaves reduced, narrowly oblanceolate, often subsessile; middle leaves the largest and broadest, acute or acuminate, the blade oblong-lanceolate or oblanceolate, tapering below into the petiole, 7 to 9 em. long (including the petiole); uppermost leaves lanceolate to linear-lanceolate, reduced. Flowers evidently diurnal, solitary or in pairs, about 2 to 5 or occasionally 23—Proc. Bron. Soc. Wasu., Vou. 42, 1929. (207) 208 Proceedings of the Biological Society of Washington. as many as 8 in the cyme, showy, often 4 cm. broad, or probably even more when fully expanded; calyx 15 to 23 mm. long, about 10-ribbed, white-crisp- hairy, rather narrow at the base, of a cylindro-funnelform type becoming turbinate (not bladdery-inflated) in fruit, the lobes lanceolate and acuminate, shorter than the tube; petals when fresh apparently varying from light hortense violet to amparo purple (according to Ridgway’s Color Standards) but shading towards amethyst violet in drying, with a broad, mostly 4- (occasionally 5- or.6-) lobed limb, the lobes 3 to 4 mm. broad; ovary stipi- tate, the stipe about equaling it; styles 3. Seeds purplish-black, reniform, about 2 mm. long, tuberculate in concentric lines. Herba perennis; rhizoma tenue; caulis tenuis erectus circiter 30 cm. altus; folia plerumque oblanceolata vel oblongo-lanceolata 7-9 em. longa subgrisea cum pilis brevibus crispis albis nullo modo viscidis, superiora lanceolata breviora; calyx circiter 10-striatus cylindro-infundibuliformis accrescens; corolla speciosa, 4+5 cm. lata pallide violacea, petalis quadri- fidis; ovarium stipitatum. It gives the authors a sense of satisfaction to name this handsomest of western silenes after its discoverer, Mr. Douglas C. Ingram, who not only is a highly efficient forest officer and an authority on range management, but is also recognized as one of the best field naturalists of the Northwest. If seed becomes available it is a certainty that this native campion will become popular in cultivation. The type specimen will be deposited in the U. S. National Herbarium. Puate VIII. Proc. Bion.

J. VAN ROSSEM. Specimens of Lampornis? viridipallens collected in El Salva- dor in 1927 show that not only is the supposedly distinct species Lampornis sybillae (Salvin and Godman) in reality a form of viridipallens, but that all told there are four recognizable geographic races. Below is given a synopsis of these with their differential characters. Lampornis viridipallens viridipallens (Bourcier and Mulsant). GUATEMALA MOUNTAIN GEM. T\rochilus] viridi-pallens Bourcier and Mulsant, Ann. Sci. Phys. et Nat. Lyon, 9, 1846, p. 321 (Coban, Vera Paz, Guatemala). Subspecific characters.—Resembles _Lampornis viridipallens nubivagus (see postea) in more bronzy green posterior upper parts and buffy tinged posterior underparts, but differs in greater extent of green spotting on sides of breast and flanks, lighter and more metallic sub-ocular streak, lighter green forehead and crown and paler and more brownish remiges. Range.—Highlands of extreme southern Mexico (Tumbala, Chiapas) south throughout the highlands of Guatemala (Coban; Chilasco; Santa Maria; Pie de la Questa; Toliman; Volcan Fuego; Guatemala City). Lampornis viridipallens connectens, subsp. nov. SALVADOR MOUNTAIN GEM. Type.—Male adult; No. 18,546, collection of Donald R. Dickey; Los Esesmiles, Dept. Chalatenango, El Salvador; altitude 8,000 feet in cloud 1Contribution from the California Institute of Technology. 2Although M. Eugene Simon in his Histoire Naturelle des Trochilidae, 1921, has treated **Coeligena”’ [Lampornis], ‘‘ Leuconympha”’ and “‘ Oreopyra”’ as distinct genera, the writers believe that the slight differences, which are chiefly those of shape of tail and color, are amply recognized by according these groups subgeneric rank. Essentially this course has already been tentatively suggested by Ridgway (Birds of North and Middle America, 5, 1911, p. 502). That the type of Lampornis Swainson is Lampornis amethystinus Swain- son and not, as designated by Gray, Trochilus mango Linnaeus would appear to be definitely settled by Opinion 30 of the International Zoological Congress, 1913. 24—Proc. Biou. Soc. WasxH., Vou. 42, 1929. (209) 210 Proceedings of the Biological Society of Washington. forest of Upper Tropical Zone; March 5, 1927; collected by A. J. van Rossem; original No. 11,409. Subspecific characters.—Wing longer than in any other race of the species. Dorsal coloration, including remiges and central rectrices, precisely like that of sybillae and therefore darker and less bronzy than either viridipallens or nubivagus; underparts intermediate between viridipallens and sybillae in extent of green spotting, but color of spotting dark as in sybillae; ab- dominal region only slightly tinged with buff; under tail coverts edged with clear gray as in sybillae; lateral rectrices gray as in viridipallens and nubivagus. Range.—Upper Tropical Zone at 8,000 feet in the humid cloud forest on Los Esesmiles, Chalatenango, El Salvador. Remarks.—This race, occupying as it does a region in a direct line be- tween the areas inhabited by viridipallens and sybillae, combines naturally enough, the characters of the two. It is not an intermediate in the sense that all of the characters are blended. The dorsal coloration, the color of the green spotting on the underparts and the color of the under tail coverts are all those of sybillae; the tail is that of viridipallens and only in the amount of green on the underparts and in the coloration of the ab- dominal region is it an intermediate in the commonly used sense. Lampornis viridipallens sybillae (Salvin and Godman). NICARAGUA MOUNTAIN GEM. Delattria sybillae Salvin and Godman, Ibis, April, 1892, p. 327 (Mata- galpa, Nicaragua). Subspecific characters.—Resembles Lampornis viridipallens connectens in relative darkness of wings; upper parts, and spotting below, but entire underparts except abdominal region so thickly spotted with green as nearly to obliterate the grayish white ground color. Differs from all other races in that the inner webs of all except the central rectrices are largely white or grayish white instead of pale gray. Culmen averaging longest of the four races. Range.—Highlands of north-central Nicaragua (Ocotal; Matagalpa; San Rafael del Norte). Lampornis viridipallens nubivagus, subsp. nov. SANTA ANA MOUNTAIN GEM. Type.—Male adult; No. 19,184, collection of Donald R. Dickey; Vol- can Santa Ana, Dept. Santa Ana, El Salvador; altitude 7,000 feet in the cloud forest on the southeast slope of the main cone; May 17, 1927; col- lected by A. J. van Rossem; original No. 12,065. Subspecific characters —Resembles Lampornis viridipallens viridipallens in size, in more bronzy green posterior upper parts and in buffy tinged pos- terior underparts, but differs in darker green back and crown, darker and more bluish remiges, blacker and less metallic sub-ocular streak and in the virtual elimination of green spotting on sides of breast. Dickey and Van Rossem—Races of Lampornis Viridipallens 211 Range.—Upper Tropical Zone at 5,000 to 7,000 feet in the cloud forest on Volcan Santa Ana proper and on the subsidiary cone of Cerro Los Naranjos, El Salvador. Remarks.—The isolated mountain inhabited by this race lies to one side of the highlands occupied by the viridipallens-connectens-sybillae chain. The form is ventrally the palest of the group, although in relatively dark wings and upper parts, it shows some approach to connectens and sybillae.

Nat. Mus., vol. 70, Art. 5, 1926, p. 33), as a possible young plumage. In 1928 Dr. Rock took a second specimen west of Yungning, Yunnan, which though differing somewhat in detail undoubtedly belongs to the same species. As both of these specimens are quite different from the figure of the type of Spelaeornis souliei given by Hartert (Nov. Zool., vol. 17, 1910, pl. 7, fig. 1) and do not agree with any published description consulted, I have reached the conclusion that they represent an undescribed species. To the American Museum of Natural History I am indebted for the loan of their specimen of Spelaeornis, the basis of the record of Spelaeornis souler from Tai-ping-pu, Yunnan (Bull. Am. Mus. Nat. Hist., vol. 44, 1921, p. 590). Unfortunately the specimen has been incorrectly determined. The wings and tail are un- barred and there are no white spots on the upper parts. The tail is shorter than the wing. The bill is dull black. As near as can be made out from Stuart Baker’s key and description (Fauna Br. India, Birds, 2 ed., vol. 1, 1922, pp. 451, 453) it belongs to Spelaeornis longicaudatus sinlumensis. If this deter- mination is correct, it is a new record for Yunnan. For many years this was the only specimen of the genus in the United States until Dr. Rock sent the specimen described below and later a second specimen, also mentioned beyond. It gives me great pleasure to name this species after the collector: 1Published by permission of the Secretary of the Smithsonian Institution. 25—Proc. Biou. Soc. WasH., Vou. 42, 1929.

Collected by Joseph F. Rock. (Original No. 1304.) Pileum argus brown, each feather rather broadly tipped with black and with a rather large sub-apical white spot; upper-parts sudan brown, each feather tipped narrowly with black and with a small triangular buffy- white spot; cheeks and sides of neck a little lighter than the back, with buffy shaft streaks, the feathers with narrow black tips; the feathers around the eye white posteriorly; throat and jugulum white; breast, sides and flanks ochraceous-tawny, the feathers of the breast and abdomen with rather broad white shaft-streaks and rather narrow black tips; the flanks with a few narrow white shaft-streaks; the under tail-coverts a little darker than the flanks, each feather with a sub-apical white bar and black tip; wing-coverts deep mouse gray with a brownish wash with a few white shaft-streaks and barred with black; flight feathers snuff brown rather broadly barred with black; tail snuff brown with narrow, irregular black bars; the upper mandible fuscous-black; the lower mandible chamois (in the skin). Wing, 48; tail, 50; culmen, 10; tarsus, 20; middle-toe, 13 mm. Remarks.—The specimen from west of Yungning, 13,000 feet, Yunnan, May, 1928 (U. 8. Nat. Mus. No. 312,284), differs from the type in having the forehead more profusely spotted with white; the white sub-apical spots and black tips to the feathers of the pileum smaller; the basal color of the crown and occiput of the same color as the back; below, the white of the jugulum extends down the center of the breast, the black apical spots are obsolescent, and the white shaft-streaks on the flanks have almost disappeared. It measures: Wing, 47.5; tail, 50.5; culmen, 10.5; tarsus, 19.5; middle-toe, 12 mm. Comparing Spelaeornis rocki with Hartert’s figure of the type of Spelae- ornis souliet, the former is lighter above with the black apical spots more conspicuous; the flanks are lighter and the black apical spots smaller; and the white of the throat extends down on the jugulum and breast. It seems strange that this species should occur so near the type locality of Spelaeornis soulier. Vol. 42, pp. 215-216 te ; De __iber 4, 1929 PRO CEED INGS OF THE BIOLOGICAL SOCIETY OF WASII!. . a! THE GLORIOSA RACE OF IXOCINCLA MADAGASCARIENSIS. BY HERBERT FRIEDMANN. ———— ooo Some months ago Mr. Hermann Grote called my attention to the fact that the bird described by Ridgway (Proc. U. S. Nat. Mus. xvi, 1893, p. 597) as Ixocincla madagascariensis rostrata was said to inhabit Aldabra and Gloriosa Islands, and that inasmuch as all the islands off the east coast of Africa, such as the Comoro group, the Seychelles, Mauritius, etc., are inhabited by distinct races, he wondered if Gloriosa birds were really identical with those from Aldabra (type locality of rostrata). On looking through the literature I find that Grote’s hesitancy in regarding the birds of Gloriosa as true rostrata is not without reason. In fact, two years after describing rostrata, Ridgway (ibid, xviii, 1895, p. 525) lists Gloriosa birds as only questionably of this race. He writes that, Oe, OWE: GO their bad condition of plumage, I have not been able to make out satisfactorily whether the Gloriosa and Aldabra birds of this species are really different or not.”’ The series from Aldabra (the type and three other birds) are all in fresh plumage, while the three specimens from Gloriosa are all extremely abraded, making plumage comparisons difficult. The collector, Dr. W. L. Abbott, noted that the birds of Gloriosa Island have an entirely different call from that of the closely allied group on Aldabra. I have compared the two series and find that the Gloriosa birds have constantly larger bills than do typical, Aldabra specimens. The wing and tail measurements are fairly simi- lar, allowing for the difference in wear. The bill character, together with the knowledge that the Gloriosa birds differ in 1Published by permission of the Secretary of the Smithsonian Institution. 26—Proc. Brov. Soc. Wass., Vou. 42, 1929. (215) 216 Proceedings of the Biological Society of Washington. habits from those of Aldabra, justifies their taxonomic separa- tion. The Gloriosa birds I take pleasure in naming after Mr. Grote, who first suggested that they might represent an un- described form. Ixocincla madagascariensis grotei, subsp. nov. Type.—U. 8. Nat. Mus. 128664, adult male in worn plumage, collected on Gloriosa Island, 26 January, 1893, by Dr. W. L. Abbott. Subspecific characters.—Similar to rostrata but with longer, stronger bill, the culmen 27 mm. in the male, 25.5-26 mm. in the females, as against 25.5 mm. in the male of rostrata and 24-24.5 mm. in the female of the latter form. Also the bill wholly bright orange red in life in grotei, while in rostrata it is orange red only for its basal half, and dusky, almost blackish, towards the tip. This character is not well shown in dried skins, but the collector noted this feature on the label of each of the seven birds collected, so it seems to be fairly constant. The dimensions of the series examined are as follows: Form Locality Sex Wing Tail Culmen rostrata Aldabra (type) of 112 101.5 25.5 do do °) 106 97.0 24.5 do do 2 110 100.0 24.0 do do — 109 95.0 24.0 grotet Gloriosa (type) of 109 95.0 27.0 do do | 2 110 97.0 26.0 do do Q 110 95.0 25.5 Remarks.—In the original description of rostrata (cit. supra) Ridgway states that it is, “‘. . . similar to true J. madagascariensis, but larger, the bill especially, and coloration paler.” The bill character is based wholly on the Gloriosa birds, and the generally larger size I find does not hold true. If anything, rostrata averages slightly smaller than typical mada- gascariensis, of which race I have examined some 13 specimens. The only reliable character by which rostrata differs from madagascariensis is in the paler coloration of the former, which has the underparts more brownish, less grayish than in the latter. Neumann (Orn. Monatsb., xxxiv, 1926, pp. 110-111) has recently de- scribed a whitish-bellied race, albiventris, from Anjouan Island, and has referred the present species to the genus Microscelis as he finds no note- worthy differences between it and Ixocincla. There can be no question but that the two are closely allied, but I prefer not to go into this matter without more extensive material of all the forms of both genera. gate jis a~ 0 6'7 3 Vol. 42, pp. 217-218 December 14, 1929 PROCEEDINGS BIOLOGICAL SOCIETY OF WAS _ In describing a new race of Attila spadiceus from El Salvador, the writers are not unmindful of the somewhat startling array of synonyms which have resulted in the past from failure to appreciate the extraordinary amount of individual variation to which the species is subject.2. However, the large Mexican races, Attila spadiceus flammulatus Lafresnaye of the Atlantic slope and Altila spadiceus cinnamomeus Lawrence of the Pacific slope, are well known to be characterized by a brown dorsal coloration, regardless of the variation displayed in the under- parts. It is with this large, brown-backed group that the series of ten birds from El Salvador belongs, not one of them possessing the slightest trace of olive above, even on the head. But since they seem to differ consistently from these other races we propose to call them: Attila spadiceus salvadorensis, subsp. nov. EL SALVADOR ATTILA. Type.—Male adult; no. 17,757, collection of Donald R. Dickey; Lake Olomega, Dept. San Miguel, El Salvador; April 7, 1926; collected by A. J. van Rossem; original no. 10,835; altitude 200 feet; “breeding con- dition.” Subspecific characters.—Resembles Attila spadiceus flammulatus Lafres- naye, of southeastern Mexico, in yellow rump and upper tail coverts and grayish brown pileum, but rest of upper parts and tail very much paler. Resembles Attila spadiceus cinnamomeus Lawrence, of western Mexico, in dorsal coloration, but rump and upper tail coverts bright orange-yellow (not ochraceous) and pileum more grayish, less brownish.

Range.—Coastal slope and coastal range of El Salvador. Northwestern and southeastern limits not yet determined. Remarks.—This form is not unlike the ochraceous phase of Attila spa- diceus citreopygus (Bonaparte) which was described by Ridgway as ‘‘Attila citreopyga luteola,”’ but is of course decidedly larger. All of the ten ex- amples of the new race are remarkably uniform above, but show the usual range of olive green, tawny and yellow suffusion on the underparts. = cS w/ C) =~ et Vol. 42, pp. 219-220 December 14, 1929 | PROCEEDINGS | OF THE BIOLOGICAL SOCIETY OF WASHINGTON — 7 SEilhigg : / ORL ES ( sok 4 i Lip & A NEW RACE OF THE HAIRY WOODPECKE EL SALVADOR. : “Bite “U5 BY DONALD R. DICKEY AND A. J. VAN ROSSEM. eum Five specimens of Dryobates villosus collected in the high mountains in north-central Salvador, prove to belong neither to the Chiapas-Guatemala race sanctorum nor to fumeus of | Nicaragua. The new race is characterized below. Dryobates villosus parvulus, subsp. nov. EL SALVADOR HAIRY WOODPECKER. i Type.—Male adult; no. 18,507, collection of Donald R. Dickey; Los i Esesmiles, Dept. Chalatenango, El Salvador; March 2, 1927; altitude 8,000 feet in the Upper Tropical Zone; collected by A. J. van Rossem, original no. 11,370. Subspecific characters.—Identical in coloration with Dryobates villosus il sanctorum Nelson of Chiapas and Guatemala, but size smaller, in fact, i smaller than any of the heretofore described races of Dryobates villosus ! in bill, tarsus and foot. Differs from Dryobates villosus fumeus Oberholser of Nicaragua in darker underparts, browner dorsal stripe and smaller size. Differs from Dryobates villosus extimus Bangs of Costa Rica and | western Panama in browner dorsal stripe and smaller bill, tarsi and feet. | Range.—8,000 to 9,000 feet in the cloud forest of the Upper Tropical Zone on Los Esesmiles, Chalatenango, El Salvador, and in contiguous parts of Honduras. Remarks.—The fact that this smallest of the races of the Hairy Wood- pecker occupies a territory between two larger forms, may be accounted- for by the hypothesis that it is a diminutive local derivation of sanctorum, just as extimus is the small southern extension of fumeus. Hairy Woodpeckers in Salvador were confined strictly to the Upper Tropical Zone and in no case was one noted in the Sonoran Zone. One of the birds collected was taken exactly on the Salvador-Honduras border, so that its extension into the southern Honduras highlands is a matter of certainty. It is notable that neither Oberholser (Proc. U. 8S. Nat. 1Contribution from the California Institute of Technology. 28—Proc. Brox. Soc. WasH., Vou. 42, 1929.

Mus., 50, pt. 6, 1914) had available any specimens from Honduras and both specu- late on the identity of the record of ‘‘ Picus jardinii”’ from Sisquatepeque, Honduras.
