REPORT.

To THE PRESIDENT AND FELLOWS oF HARVARD COLLEGE: —

Most of the instruction and the opportunities for research in
Zoodlogy, Geology, and Geography in Harvard University and in
Radcliffe College during the Academic year 1919-1920 were given,
as in recent years, in the Laboratories and Lecture Rooms of the
Museum.

The sixteen courses or half courses in Zodlogy were taken by
317 students in Harvard University, and the seven courses or half
courses were taken by 88 students in Radcliffe College.

In 1918-1919 these courses and students were: —

Harvard:— 14 courses, 222 students.

Radcliffe:— 6 courses, 81 students.

In Geology and Geography thirty courses or half courses were
taken by 504 students in Harvard University and eight courses
or half courses were taken by 126 students in Radcliffe College.

In 1918-1919 these courses and students were: —

Harvard:— 19 courses, 333 students.

Radcliffe:— 2 courses, 23 students.

The field-work undertaken during the year, while limited in the
aggregate, has given some interesting results. Prof. P. E. Ray-
mond spent six weeks on the borders of Lake Champlain in Ver-
mont and New York, collecting in the Chazy and nearby forma-
tions. On Isle La Motte, Vermont, he secured the largest known
Palaeozoic sponge and some corals from the oldest known coral
reef. Professor Raymond also discovered an apparently new
locality for Palaeozoic fossils in Topsfield, and collected a number
of specimens from some of the already known localities in the
vicinity of Boston.

For somewhat more than three months, February to June 1920,
the U. S. Fisheries Steamer ALBATROSS carried on a successful
exploration in the Gulf of Maine and adjacent waters. As in
recent years, the scientific work of the ALBATROss in the Gulf of
Maine was under Dr. H. B. Bigelow’s direction, and he was in

4 ANNUAL REPORT OF THE

personal charge during a part of this season’s cruise. The work
included a general hydrographic survey of the Gulf of Maine,
Georges Bank, and the continental shelf south of Cape Sable,
with the usual trawl- and net-hauls, temperature and tidal data,
etc.

Mr. E. R. Dunn spent the summer of 1919 in the mountains of
Virginia, North Carolina, Alabama, and Tennessee, and secured
a large series of reptiles and amphibians. Mr. Dunn’s work in
Costa Rica during July, 1920, will be noticed in the Report for
1920-1921.

Mr. W. 8. Brooks worked with Dr. Thomas Barbour during the
winter and early spring, collecting in Cuba and among the Florida
Keys; they secured many desirable mammals, birds, reptiles,
amphibians, and fishes. Mr. Brooks also spent several weeks on
Anticosti where he collected a few mammals and birds and a small
series of shells and insects. Prof. Theodore Lyman kindly aided —
Mr. Brooks’s work in Anticosti.

Dr. G. M. Allen visited Haiti during August and early Septem-
ber, 1919, and though unsuccessful in his search among the cave-
deposits, the main object of his trip, he collected a few bats, and a
number of reptiles, three of the latter proving new species. The
field-work of Dr. Allen and Messrs. Dunn and Brooks was due to °
the generous assistance of Dr. Thomas Barbour, who also provided
for some additional work upon the collections.

The ornithological and conchological departments have benefited
by the voluntary work of Messrs. T. E. Penard and E. G. Hum-
phrey, to whom the thanks of the Museum are due. The excel-
lent condition of the large collection of Araneae is owing to the
interest and care bestowed upon it by Miss E. B. Bryant.
~The William Brewster bequest constitutes not only the most
important accession received during the year, but one of the chief
scientific acquisitions received since the foundation of the Museum
in 1859.

The terms of the bequest are printed as Appendix A (infra,
p. 42). 7

The bequest includes: —1. Collection of mounted birds and
bird skins. 2. Collection of nests and eggs. 3. Collecting —
apparatus. 4. Books, pamphlets, prints, and Audubon portrait.

MUSEUM OF COMPARATIVE ZOOLOGY. 9)

5. Manuscript journals, note books, etc. 6. $60,000.— to es-
tablish a fund for the ornithological department. (The income
available on the termination of certain life interests).

The series of bird skins and mounted birds, approximately
40,000 in number is almost wholly American; it represents Mr.
Brewster’s personal collecting, chiefly in New England, in the
middle west, the Southern States, and in Trinidad, supplemented
by material acquired by exchange and purchase. Though the
greater part of the collection is from a somewhat limited number
of localities, there are few of the states from Maine to Washington
that are not more or less adequately represented, while the large
series of many of the species will allow many advantageous ex-
changes. The whole collection is thoroughly catalogued and its
excellent condition is well known to ornithologists.

The Brewster collection of nests and eggs is also very large and
fills a want most generally felt, as the odlogical side of ornithology
has been inadequately. developed. The T. M. Brewer collection
received in 1875, though of considerable historical value, is made
up very largely of single, end-blown eggs; the Brewster collection,
on the other hand, consists of entire clutches conserved with much
nicety.

‘The additions to the Library, while principally relating to birds,
include many volumes dealing with other lines of zodlogical work,
travels and voyages, and complete files of Forest and Stream,
Rod and Gun, and a number of similar serials. Among the orni-
thological items are most of the earlier short-lived serials, not
easily obtained today, many authors’ separates, chiefly systematic
and faunal, and a very considerable number of the numerous
popular books of recent years. The Brewster accessions, recorded
to 1 August, number 1,701 titles.

Mr. Brewster’s journals and note-books record with unusual
felicity his field observations for a term of forty-nine years. The
Museum hopes to publish his Concord Notes and those relating
to the Birds of Lake Umbagog. About one half of the latter was
practically ready for the printer at the time of Mr. Brewster’s
death, and it is to be regretted that the funds of the Museum and
the copy prepared by members of the Museum staff awaiting
publication, preclude a prompt issuance of the same.

6 ANNUAL REPORT OF THE

The income of the Brewster Fund, when available, will enable
the department of ornithology to secure some of the desirable
specimens which are from time to time offered for sale.

So large an acquisition as the Brewster collection of bird skins,
and the proper interpolation of the same in the Museum series,
could not be accomplished readily at any time, and it is owing
to the kindness of Dr. E. L. Mark, who has allowed the storage of
very many of the Brewster cases in the central space of the large
zoological laboratory adjacent to the ornithological collections,
that the immediate use of the Brewster collection of bird skins is
possible. It is only through Dr. Mark’s good offices, the invasion
of rooms devoted to departments other than ornithology, and the
closing of one of the exhibition rooms, that the temporary storage
of the Brewster collection has been brought about. And this
crowded and unsatisfactory condition, though emphasized by
the Brewster bequest, is not confined to the ornithological depart-
ment. It is true with hardly an exception in all departments;
the great gift of the Nathan Banks entomological collections
would add little to the scientific resources of the Museum were
they not still in charge of their generous donor; the recent addi-
tions to the department of invertebrate palaeontology are stored,
rather than conveniently arranged for reference and study; the
collections of recent Echini, one of the great treasures of the
Museum, are housed in part in the basement, in part on the fifth
floor, with the work room of the Curator on the second floor,
and the collections of lower vertebrates are similarly disunited.

Relief from this condition can be obtained by the removal of
zoological instruction from the Museum to a nearby biological
laboratory building, an event of three-fold consequence: facilities
for research would be enlarged, an ever present and ever increas-
ing menace to the Museum collections would be eliminated, and
it would provide for the growth and expansion of lines of work
which should not be carried on in a building containing typical
historical material, coincident from the beginning of systematic
zoology to the present day.

For an accession of unique interest and value, the Museum is
indebted to the American Museum of Natural History. At the
second meeting of the American Association for the Advancement

MUSEUM OF COMPARATIVE ZOOLOGY. a

of Science, held in Harvard Hall, Cambridge, 14 August, 1849, Prof.
Louis Agassiz read a paper “On the fossil remains of an elephant
found in Vermont”’ stating that the specimens which were found
“a few weeks ago, in the construction of the Rutland and Bur-
lington Railroad, upon the slope of Mount Holly * * * had been
presented to the museum of the Lawrence Scientific School by
Mr. Samuel Henshaw, of Boston. * * * He considered this a very
valuable contribution to the scientific school; but he was sorry to
say that it was in itself the museum, which was just beginning
to be formed.” Professor Agassiz mentions a tooth and tusk only;
in 1852, however, Dr. J. C. Warren, in his “Mastodon giganteus
of North America,” records as received from the same locality
and donor “some vertebrae and ribs,” and in the second edition
of his work, (Boston, 1855), Dr. Warren gives an excellent figure,
(Plate 28B), of the tooth. The whole of this Vermont material
was doubtless in Dr. Warren’s hands for study, and remained
in the Warren Museum, Chestnut Street, Boston, until 1906,
when the late Mr. John P. Morgan presented the Warren Collec-
tion to the American Museum. The identity of the Vermont
material was established by Mr. Walter Granger, and the Ameri-
can Museum, with a nice sense of right which recalls the position
taken by Sir Joseph Banks in restoring natural history collections
to France, sent the tooth to Cambridge, and most generously
added the specimens originally given to Dr. Warren, in order that
all the specimens of “the first true elephant found in a fossil state
in the Northern American States “might be kept together. The
tusk mentioned by Professor Agassiz has not been traced, and
quite possibly may have disintegrated. Thus, though the col-
lections forming the museum of the Lawrence Scientific School
came by heritage to the Museum of Comparative Zodlogy, the
first recorded specimen in the collection of the School dates as a
Museum of Comparative Zodlogy accession from July, 1920,
more than sixty years after the laying of the corner stone of the
present Museum in June, 1859.

The Museum is indebted to Mrs. Margaret Stearns for the C. A.
Stearns collection of shells, a collection of more than 2,000 species,
with many specimens exceptional for size and beauty. The series
from Lower California is of distinct scientific value as a record

8 ANNUAL REPORT OF THE

of the work of one of the ablest students of Pacific Coast Mollusca,
the late R. E. C. Stearns.

The collections of mammals, birds, reptiles, and amphibians,
have received many additions, the generous gifts of Dr. Thomas
Barbour. A second series, 350 species, of Japanese shells, choice
specimens selected from the stock of Y. Hirase, is also the gift of
Dr. Barbour. An excellent series of nearly 300 skins of mam-
mals, largely with skulls, chiefly from western North America,
is the gift of Dr. L. C. Sanford.

The Museum is indebted to Dr. R. V. Chamberlin for a collec-
tion of fossils from Utah; to Prof. C. C. Nutting for a collection
of echinoderms; to the American Museum of Natural History for
twenty-two species of land mollusks from the Belgian Congo;
to the Bermuda Biological Station for Research, Dr. E. L. Mark,
Director, for many marine mollusks from Bermuda; to Dr. R. C.
Murphy for a collection of arachnids from the Guano Islands of
Peru; to Mr. F. C. Bowditch for a large series of Chrysomelidae;
to Mr. G. H. Edwards for the tooth of a fossil elephant from Mon-
tana; to Mr. Heyward Cutting for an Alaskan Moose, and to
Col. John E. Thayer for a series of small mammals from New
Mexico.

From Dr. L. C. Sanford the Museum has received in exchange
a series of 73 species, 101 specimens of bird skins, and from the
U. S. National Museum, 59 species, 192 specimens; both series
contain many species new to the collection of the Museum; those
from the United States National Museum were obtained by Mr.
H. C. Raven in Celebes, Dr. Sanford’s from many localities not
well represented in most collections.

These accessions and those received during recent years show a
growth that justifies the hope that the Museum will, in the near
future, afford adequate facilities for the systematic study of the
birds of the World. In the Sharpe Hand List 2,647 genera of
recent birds are recognized; the Museum collection at present
contains specimens of 2,204 genera.

Dr. G. M. Allen worked three days each week upon the collec-
tions of Mammals. He continued his study of the fossils collected
in the early Eighties by Messrs. Garman, Clifford, and Sternberg,
in the Tertiary formations of the Middle North American states.

MUSEUM OF COMPARATIVE ZOOLOGY. 9

He also attended to the usual exchanges and loans, supervised the
use of the collection by graduate students and others, and com-
pleted a study of the Dogs of the American Aborigines, and one
on the cranium of a new fossil cetacean.

Mr. James L. Peters was employed for five months assisting
Mr. Bangs in the arrangement and identification of the collection
of bird skins.

Mr. W. F. Clapp’s work upon the collection of mollusks has been
divided between the care of accessions, old and new, several thou-
sand lots, and a continuance of a study preparatory to a report on
the Mollusca collected by Dr. W. M. Mann in the Solomon Islands.

Mr. George Nelson, whose skill and versatility as a Museum
Preparator has been noted in many recent reports, has mounted
for exhibition a number of mammals, birds, and reptiles, prepared,
mounted, and repaired many skins and skeletons of birds and
mammals, developed, restored, and cast many fossils; his knowl-
edge and expertness in photographic work, and his mechanical
handiwork have been most serviceable. Mr. Nelson’s selection
by Dr. L. C. Sanford, as the Preparator to make over and remount
- the Audubon Great Auk, was a deserved recognition of his un-
usual ability, and the result is most satisfactory and gratifying
alike to Mr. Nelson, Dr. Sanford, and the Museum. |

Mr. Richard Bliss, whose death occurred at Newport, 7 January,
1920, served as a Museum Assistant for several years, aiding
Professor Agassiz in the care of the ichthyological collections.
Professor Agassiz’s most interesting letter answering Mr. Bliss’s
application for admission as agspecial student at the Museum is
printed as Appendix B (infra p. 42, 43).

Additional letters of Louis Agassiz to Prof. Benjamin Peirce
and Dr. J. B. Holder, the latter the gift of Mrs. C. F. Holder, have
been received during the year.

The Library contains 57,414 volumes, and 59,986 pamphlets;
1,610 volumes and 2,278 pamphlets have been received during the
year. Mr. Brewster’s bequest included, in addition to the books
and pamphlets already mentioned, William Stone’s admirable
copy of Healey’s portrait of Audubon, and a few Auduboniana
given Mr. Brewster by Audubon’s granddaughter, Miss Maria
_Audubon. From Mr. Banks the entomological section of the

10 ANNUAL REPORT OF THE

Library has received many additions of recent books and author’s
separates, and Prof. W. M. Davis, Sturgis Hooper Professor of
Geology, emeritus, following the policy of his distinguished pre-
decessor, adds each year many volumes and pamphlets to the
Whitney Library.

A profile plaque of Prof. Jules Marcou by Max Daudet is the
kind gift of Mrs. Powell. A volume of the records of the Harvard
Natural History Society, with much contemporaneous corre-
spondence, has been received from Dr. R. M. Field.

Miss E. L. Anthony resigned her position in the Library in
September, 1919. Her term of employment began in 1869; for
some years she assisted in the conchological department but
most of the time she served faithfully in the Library. Her Mu-
seum associates were glad to join in testifying their regard and to
wish her many years of contentment.

The publications of the year include one number of the Memoirs,
eight numbers of the Bulletin, and the Annual Report, a total of
749 (46 quarto and 703 octavo) pages, illustrated by 25 (6 quarto
and 19 octavo) plates. The number of the Memoirs contains a
report on the collection of Asteroidea (Star-fishes) obtained during
the expedition to the Eastern Tropical Pacific, in charge of Mr.
Agassiz, by the U. S. Fish Commission Steamer ALBATROSS, in
1904-1905. One of the Bulletins contains a report on the birds
collected during the expedition of the ALBATROsS in the Tropical
Pacific in 1899-1900; the other Bulletins, seven in number, are
reports based on Museum collections.

REPORT ON THE ZOOLOGICAL LABORATORY.

By E. L. Marx.

During the year 1919-1920 the courses of instruction in Zodlogy
were substantially the same as in the period immediately preceding
the entrance of the United States into the War, and were given by
the same instructors. The number of students who completed
each of the courses is given, as heretofore, in tabular form. Table
_ I shows for each course the number of Harvard students from each
of the classes of Harvard College and other schools represented,
and Table II the same for each of the classes of Radcliffe College.

J. M. D. Olmsted.

Courses 7a, 7c, and 10 were given at the Bussey Institution, all
others in Cambridge. Of the Harvard students in Zodlogy 14b,
five took the course with work in the laboratory; of the Radcliffe
students, one. In Zodlogy 17, four Harvard students and one
Radcliffe student took the course with work in the laboratory.

The University Extension Course in Elementary Zodlogy,—
fifteen lectures accompanied with laboratory exercises — was
given by Professor Parker, during the first half year. Eight
persons attended the course, five of whom took the examination.
The assistants were Messrs. S. W. Chase, and H. G. Coar.

The privileges of the Laboratory were granted during the first
half year to Professor A. O. Gross of Bowdoin College, who worked
chiefly under the direction of Professor Parker, and for a short

period during the second half year to Professor T. Kawamura of
Kyoto University, Japan, also working under Professor Parker.

The aggregate research work carried on was counted as equiva-
lent to courses as follows: —in Harvard, Zoédlogy 20a and 20b,
under Professor Mark, four and one half courses; Zodlogy 20c,
under Professor Parker, eight and three fourths courses; Zodlogy
20e and 20g, under Associate Professor Rand, four and one half
courses; in Radcliffe College, Zodlogy 20g under Associate Profes-
sor Rand, one half course.

The degree of Doctor of Philosophy was conferred during the
year on four persons: in February, 1920, on Vasil Obreshkove,
whose thesis was entitled “The photic reactions of tadpoles in
relation to the Bunsen-Roscoe law,” and on James Montrose
Duncan Olmsted, whose thesis was entitled “Experiments on the
olfactory and gustatory organs of Amiurus nebulosus (Lesueur) ”’;
in June on Edward Frederick Adolph, whose thesis was entitled
“A quantitative study of the interrelations of oxygen and carbon
dioxide with haemoglobin in blood”; and on Herbert Greenleaf
Coar, whose thesis was entitled “The shell of Balanus eburneus:
A contribution to the study of the operculate Cirripedia.’”’ In
June Samuel Wood Chase was recommended for the degree of
Ph.D. to be conferred at mid-year 1921, he having presented a
thesis — “The mesonephros and urogenital ducts of Necturus
maculosus, Rafinesque’”— which was approved, and having passed
the doctor’s examination on June 9, 1920.

Two students and the Director spent about six weeks at the
Bermuda Biological Station, which was open from the twenty-first
of June till the sixth of August.

The Harvard Table at the Marine Biological Laboratory, Woods
Hole, was shared by two graduate students, that of Radcliffe
College by a graduate and an undergraduate, of the class of 1922,
of Radcliffe College.

Aid to the amount of $370.00 was furnished from the Humboldt
Fund to Harvard research students at the Bermuda Station and
the Woods Hole Laboratory, the payments, however, fall within
the fiscal year 1920-1921.

The Zodlogical Club held twenty-four meetings during the year,
at which twenty-five original papers and five reviews were pre-

REPORT OF THE STURGIS HOOPER PROFESSOR OF
~ GEOLOGY.

By Rearnaup A. DALy.

Apart from the time devoted to teaching and the duties of a
department chairman, the year was spent in laboratory and field
research. ‘Two papers on the hypothesis of a recent, eustatic shift
of sea-level to the amount of about twenty feet, another on the
systematic warping of the earth’s crust in the belts marginal to
the Pleistocene ice-caps, and a fourth on the relation of the plane-
tesimal hypothesis to the earth’s history and constitution were
written and published. Laboratory studies on the 1919 collection
of Samoan rocks and on the chemical precipitation of limestone
were begun. A special investigation of recently published theories
of mountain-building was also begun.

During the summer a field revision of data bearing on the post-
Glacial warping of the Atlantic coast region was made. De Geer’s
measurement of uplift at Mount Desert, Maine, was confirmed.
It was found that the zero isobase crosses the Nova Scotia coast
between Yarmouth and Digby and runs across northern Nova
Scotia to a point on the Strait of Northumberland, north of Pictou.
It lies between Port-aux-Basques and St. George’s Bay in south-
western Newfoundland, and between Cape Bonavista and Twil-
lingate in eastern Newfoundland. As a result of deceptive field
appearances and of hasty field work at Signal Hill in 1900, the
writer published the statement that St. John’s was uplifted (see
Bull. M. C. Z., 1902, 38, p. 258). This assertion is quite wrong,
all the coast around the city showing evidence of recent subsidence.
_ Many points studied both on the east and west shores of New-
foundland as well as on the Canadian and Newfoundland Labrador
coast showed that the island has been tilted toward the south,
with maximum uplift of 425 to 450 feet at its northern extremity.
The 1900 measurement of uplift at and near Battle Harbor,
Labrador, was confirmed.

16 ANNUAL REPORT OF THE

REPORT ON THE DEPARTMENT OF GEOLOGY AND
GEOGRAPHY.

By Recinatp A. DALY.

The year’s changes in the teaching force of this department
included: the much regretted resignation of Professor Atwood, to
assume his new duties as President of Clark University; the
absence of Professor Graton, on Federal service at Washington;
the voluntary service of Professor W. M. Davis (emeritus) in
giving advanced instruction in physiography; and in the appoint-
ment, as assistants, of Messrs. T. H. Clark, E. C. French, N. E. A.
Hinds, P. E. James, A. Wandke, and R. F. Webb. Professor
Smyth conducted the course Geology 10, ordinarily given by

Mr. Roderick Peattie received the degree of Doctor of Philo-
sophy, the title of his thesis being “Geographic conditions of the
Lower St. Lawrence Valley.” The degree of Master of Arts in
geology was conferred on Messrs. I. B. Crosby, N. E. A. Hinds,
W. M. Rau, E. F. C. Smith, and A. C. Swinnerton.

Professor Atwood conducted an unusually large number of
courses, arousing widespread interest in scientific geography.
His resignation and the failure of reappointment of a successor
mean that for the near future at least both the University and
Radcliffe College must suffer prestige so far as the work of this
department is concerned. The department has obviously lost
the leadership in geographical studies which it had for many
years. During the year Professor Atwood published a highly
valuable grammar school geography, based on the well-known
work by Frye, but completely rewritten.

* Not included in recent Reports.

18 ANNUAL REPORT OF THE

In addition to his regular courses in geology (5, 12, 15, and 16)
Professor Woodworth conducted a course on the elements of
seismology (Geology 19) to a few students at their request. In
Radcliffe College, he gave two half courses, equivalent to Geology
4 and 5 of the Harvard list.

Professor Woodworth carried on the work of the seismological
station. By request the exchange of the monthly bulletin of
earthquakes registered at the Station has been extended to the
Osaka Meteorological Observatory and to the Central Meteoro-
logical Observatory at Tokyo, Japan, beginning January 1, 1920.
Mr. Randolph C. Ray, preparator, has given about an hour a day
to the routine work of the Station.

As a Geologist of the U. 8S. G. S., Professor Woodworth gave
much time to the revision of a report on the geology of Cape Cod
and adjacent islands. ‘The summer of 1920 was spent on Martha’s
Vineyard. A new locality for the occurrence of the Weyquosque
glacial gravels was examined on the land of Mr. Ernest Flanders
in Chilmark and a small collection of the water-worn Miocene
sharks’ teeth characteristic of this horizon was made. A well-
preserved coral or bryozoan found in a chert pebble from the
Miocene bed in Gay Cliffs was submitted to Mr. E. O. Ulrich, for
a determination of its value as a horizon marker. Other chert
pebbles from the same bed have been referred to a Helderberg
horizon. Professor Lull of Yale University kindly undertook a
study of the vertebrate foot print collected in the upper Carboni-
ferous at Attleboro, Mass., in 1916 by Mr. Fred. W. Garnjost.

Professor Ward gave his courses as usual, with the exception of
Meteorology 3, which, with the approval of the President, was
omitted. Further progress has been made in the preparation of a
book on the climatology of the United States, and as President of
the American Meteorological Society, a good deal of time has been
given to the work of that Society. The summer was spent in the
preparation of a presidential address. The Laboratory teaching
collections are in good condition.

Professor Raymond gave Palaeontology 1 and 2 in the new
form. The former was arranged to illustrate matter of more
general interest regarding the progress and evolution of life; the
latter takes up the subject of invertebrate Palaeontology from a

20 ANNUAL REPORT OF THE

REPORT ON THE MAMMALS.

By Outram BaAnGs.

During the year 561 specimens were received.

The more important accessions include: a series of nearly 300
skins, mostly with skulls, chiefly from western North America,
the gift of Dr. L. C. Sanford; thirty-seven specimens collected in
New Mexico, presented by Mr. John E. Thayer; forty-seven
specimens from Arizona, twenty-five from Florida, and a number
of bats from Haiti, all the gift of Dr. Thomas Barbour.

A young Lion from Franklin Park, the gift of the City of Boston,
has been mounted for exhibition.

Single specimens or small series have been presented by Mr.
and Mrs. S. K. Lothrop, Messrs. G. M. Allen, Outram Bangs, L. C.
Dunn, G. H. Edwards, A. V. Kidder, C. R. Lamb, J. L. Peters,
A. 8. Pope, W. L. Smith, and Oliver Trafford. A few specimens
were received as the bequest of William Brewster.

Exchanges have been made with Amherst College, the American
Museum of Natural History, the Naturhistoriska Riksmuseum,
Stockholm, and the South African Museum.

REPORT ON THE BIRDS.

By Outram BAnGcs.

In addition to the William Brewster bequest of skins, mounted
birds, nests and eggs, the largest single accession ever received
by the Ornithological Department, 608 bird skins have been added
to the collection.

We are indebted to the U. S. National Museum for 192 bird
skins from Celebes, twenty-two of the fifty-nine species, hitherto
not in the collection; to Dr. Thomas Barbour for twenty skins
from Anticosti collected by Mr. W.S. Brooks and for 109 collected
by himself and Mr. Brooks in Cuba, Florida, and among the
Florida Keys. Single skins or small series have been presented
by Miss M. J. Sitgreaves and by Messrs. Thomas Barbour, W.
Cameron Forbes, G. E. Hodsdon, F. H. Kennard, T. E. Penard,
J. L. Peters, J. C. Phillips, O.. W. Ricketson, L. C. Sanford, C. H.
Taylor, Roland Thaxter, and J. E. Thayer.

Specimens have been received in exchange from the U. S.
Biological Survey, the Carnegie Museum, and from Messrs. H. R.
Coale, J. H. Fleming, Nagamichi Kuroda, L. C. Sanford, and A.
T. Wayne; Dr. Sanford’s series consisted of 101 skins, seventy-
three species, of which twenty-eight were new to the collection.
Skins have been sent in exchange to Messrs. Fleming, Kuroda,
Sanford, and Wayne, and to the American Museum of Natural
History.

For purposes of study, skins have been loaned to the American
Museum of Natural History, the Carnegie Museum, the Field
Museum of Natural History, the Museum of Vertebrate Zodlogy,
University of California, the U. S. Biological Survey, and to
Dr. C. H. Townsend. We are indebted to the American Museum
of Natural History, the Carnegie Museum, the Field Museum of
Natural History, and the U. S. National Museum, for the loan of
many bird skins.

Messrs. T. E. Penard and F. H. Kennard continued their studies
during the year, and Mr. J. L. Peters was employed for five months,
assisting in the general work of the Department.

724 ANNUAL REPORT OF THE

REPORT ON THE REPTILES AND AMPHIBIANS.
By Tuomas BaARBourR.

The year has been an unusually fortunate one as more than the
customary amount of interesting material has been received.

Dr. G. M. Allen spent August and September, 1919, in Haiti,
visiting also Gonaive Island where several new species were
secured, and since that time, thanks to his diligence, most of the
new material has been entered on the register and card catalogue
and intercalated in the collection.

Mr. E. R. Dunn collected during the summer of 1919 in the
high mountains of the Southern States and secured very many
beautifully preserved urodeles, as well as other amphibians and
some reptiles, in all 855 specimens of 55 species. Early in the
summer of 1920 he went to Costa Rica, and the shipments already
received indicate that he is reaping a rich harvest both in the
tropical lowlands and in the higher altitude.

From December to the end of April, I was in Florida and Cuba,
where, with the welcome help from Mr. W. 8. Brooks, many
desirable mammals, reptiles, amphibians, and fishes were obtained.

The series of Ranae was revised by Mr. Dunn, and the new cards
show that the collection has ninety-eight of the 165 species re-
cently recognized by Boulenger. The collection of Urodeles con-
tains thirty-five genera and 119 species.

Dr. Mook of the American Museum of Natural History studied
the skeletal material of the crocodilians and has borrowed seven
skulls and six skeletons. Mr. G. K. Noble of the same Museum
has also studied our Peruvian material and 420 specimens have
been loaned him for study.

Gifts have been received from the United Fruit Company, Dr.
Malcolm Smith, Mr. C. A. Mosier, Mr. Arthur Loveridge, and
Mr. E. R. Dunn. |

Excellent material has been obtained by exchange from the

24 ANNUAL REPORT OF THE

REPORT ON THE FISHES.
By SAMUEL GARMAN.

Shrinkages in additions to the collections during the years of
the war have permitted more attention to previous donations and
purchases, to examinations and comparisons of accumulations of
duplicates and other specimens gathered during long periods by
many students in the furtherance of their investigations, material
laid aside for consideration in times of expected leisure that
never came, or had been overlooked in changes of interest. The
manipulation of these accretions led to surprises in discovery of un-
suspected values, and at the same time induced numerous reduc-
tions in bulk on the shelves or in greater increase in economies of
alcohol and glass ware.

Among the results in Let oe in the older material has been the
discovery or recovery of numerous specimens of historical interest,
the importance of which does not diminish in the length of time
since their original notices. All this is included in the care of the
collections; it was accompanied by skeletal and other anatomical
preparations for later publication, by revision of work formerly
done, and by continuation of uncompleted researches.

REPORT ON THE ENTOMOLOGICAL DEPARTMENT.
By NatHan BANkKs.

During the past year gifts of specimens have been received from
Messrs. C. F. Baker, W. S. Brooks, A. N. Caudell, T. D. A.
Cockerell, C. W. Johnson, C. H. Kennedy, C. S. Ludlow, James
McDunnough, J. D. Sornborger, W. M. Wheeler, and E. B.
Williamson. : .

Several lots of Brazilian Neuroptera, mostly small species, were
purchased from Mr. H. 8. Parish.

Much of the time was spent in identifying Neuroptera and
Fossorial Hymenoptera, and collections were named for the
Boston Society of Natural History, the State Entomologist of
_ Pennsylvania, the North Carolina Department of Entomology,
Messrs. George Barber, A. P. Morse, and E. M. Walker.

Material from the Rhodesian Museum and the California
Academy of Sciences was partly named.

Several hundred types have been located, verified, and num-
bered. Species-labels have been written and attached to many
thousand specimens. About 8,000 insects have been pinned.

The collection has been inspected twice, and very little infesta-
tion seen at either time.

Visitors to study the collection, outside of many visits from
local entomologists, were Messrs. M. W. Blackman, R. W. Daw-
son, W. T. Davis, A. Emerson, H. C. Fall, M. D. Leonard, E. H.
Strickland, R. Webber, and F. X. Williams.

26 ANNUAL REPORT OF THE

REPORT UPON THE MYRIOPODS, ARACHNIDS, AND
WORMS.

By Ratrpy V. CHAMBERLIN.

Aside from several smaller lots, the collection of Pacific Coast
Polychaeta of the California Academy of Sciences, and a collection
of Pacific polychaetes and sipunculids from the Geological Survey
of Canada, were received for study during the year. Some time
was spent in working up material for reports on the Polychaeta and
‘ Gephyrea of the Canadian Arctic Expedition.

The most important additions of Arachnida included several
shipments of material from Prof. C. F. Baker of Los Bajos,
Philippines. A collection of arachnids from the Guano Islands of
Peru was received for study from Mr. R. C. Murphy and a report
was prepared upon the same. ‘The types in this collection have
been given to the Museum. Several smaller collections of arach-
nids were also identified for individuals and institutions.

Most of the year was devoted to work upon the Myriopoda. ~
The material available from the Bermuda Islands was reviewed
and a report upon the fauna of the region was completed. The
material from the East Indian Region in the collections of the
Museum, excepting important lots from the Philippines recently
received from Prof. C. F. Baker, was identified, and a paper de-
scriptive of the new forms prepared. A paper was also prepared
upon myriopods collected in India by Prof. C. A. Kofoid, to whom
the Museum is indebted for the first set of specimens. A revisional
study was made of the Mecistocephalidae. The remaining por-
tion of the year was given up principally to the study of the
Chilopoda and the Diplopoda of the Bryant Walker Expedition
to Colombia and British Guiana. A report upon these collections
was prepared.

For arachnids and myriopods not otherwise acknowledged the
Museum is indebted to Messrs. J. H. Emerton, J. M. Aldrich,
H. A. Allard, S. C. Chamberlin, E. R. Sasscer, H. L. Sanford,
W. A. Hilton, L. O. Howard, H. E. Hubert, and Frits Johansen.

REPORT ON THE ECHINODERMS.

By Huspert Lyman C.Lark.

Much of the time during the past year has been given to a
continuation of the work on the collection of holothurians. The
critical study of more than 200 specimens of Stichopus led to the
preparation of a report involving the revision of the genus. A
‘similar study has been made of the Synaptinae, resulting in the
discovery of seven undescribed species in the Museum collection.
During the spring, the Echini taken by the University of Iowa
Barbados-Antigua Expedition were studied and a report prepared.
Some time has also been given to further study of the brittle-stars
of the Amphiuridae.

The accessions for the year were about 200 specimens, chiefly
from the University of Iowa, through Prof. C. C. Nutting, and from
Mr. D. Thaanum of Hilo, Hawaii. Other donors, to whom
thanks are due, were Miss Mildred Bush, Prof. G. H. Parker, Dr.
A. G. Mayor, the Bermuda Biological Station, Prof. E. L. Mark,
Director, and Mr. W. M. L. Wilson.

28 ANNUAL REPORT OF THE

REPORT ON THE COELENTERATES.

By Henry B. BIGELow.

For accessions during the past year, the Museum is indebted to
Prof. G. H. Parker, series of Renilla from San Diego; the Cana-
dian Geological Survey, Medusae from British Columbia; Dr.
Thomas Barbour, Florida Medusae and Siphonophorae; Dr. H. J.
Van Cleave, Medusae from Puget Sound. .

The Autumn was spent in completing the reports on the Cana-
dian Arctic Medusae, and on the “Grampus”’ Cruises of 1916.

From the middle of February till the end of May, I was in charge
of explorations of the U. S. Fisheries Steamer ALBATROSS, com-
mander L. H. Wallace, U. S. N., commanding, in the Gulf of
Maine and adjacent waters. Sailing from Norfolk, February 19,
the ALBATROSS proceeded to Boston, where I joined her, making,
en route, a series of trawl hauls along the outer edge of the con-
tinental shelf, and a section across the western end of Georges
Bank. A general hydrographic survey of the Gulf of Maine,
Georges Bank, and the Continental Shelf south of Cape Sable,
Nova Scotia, was carried out during March, and repeated in April
to follow the seasonal changes. During the first half of May, the
ALBATROSS worked a third set of stations in the western side of the
Gulf of Maine, besides conducting a series of experiments on the
flotation of the eggs of the haddock; ran a second section across
the west end of Georges Bank, and finally returned to Norfolk.

Thanks to the efforts of Commander Wallace, his officers and
men, our cruises proved very successful. Notwithstanding the
stormy weather to be expected in early spring, we worked 89
stations, took 436 temperatures at serial depths, collected 418
water samples, the salt content of which has since been determined,
and made 360 hauls with the various nets. One full tidal record
with the Ekman Current Meter was obtained.

As in past years, I have had general supervision of the scluntiae

observations made by the U. 8. Coast Guard Steamer SENECA on
the international ice patrol off the Grand Banks, April-June, by
the observer, Mr. A. L. Thuras. Special mention should be made
of Mr. Thuras’s perfection of an accurate and convenient ap-
paratus for determining the salinity of the sea water on ship
board by its electric conductivity.

Since May my time has been occupied with the examination of
the Plankton collections of the ALBATROSS.

30 ANNUAL REPORT OF THE

REPORT ON INVERTEBRATE PALAEONTOLOGY.

By P. E. Raymonp.

The Curator spent six weeks of the summer of 1919 in collecting
from the Chazy and adjacent formations on the borders of Lake
Champlain in Vermont and New York; as a result forty-two
drawers of specimens chiefly trilobites, gastropods, and brachio-
pods were added to the collection. All have been cleaned, identi-
fied, and labeled. Many of the species were described by the
Curator in earlier reports on the same region, and are to be found
in but few museums. A few undescribed species were obtained.
Unique specimens, the largest known Palaeozoic sponge, the
largest known hypostoma of a trilobite, and corals from the oldest
known coral reef, were discovered on Isle La Motte, Vt.

In the spring and summer of 1920 a number of short trips were
made to the fossil-bearing localities in the vicinity of Boston, and
a number of specimens collected. What appears to be a new
locality for Silurian or Devonian fossils was found in the south-
western part of Topsfield by Dr. A. F. Foerste and myself. Dr.
Foerste obtained fossils from this neighborhood many years ago,
but after a careful search we were not able to rediscover the old
collecting place, although the new one is probably in its immediate
vicinity.

In addition to the material collected in 1919, a number of smaller
collections, mostly in the stratigraphic collection, have been
identified, and the Asterozoa have been reidentified and labeled.
A study was made of the Archaeocyathinae, about whose structure
new facts were discovered, and papers written descriptive of some
novel forms of Beatricidae, a starfish, and a crinoid, as well as the
results of an investigation into the nature of Phytopsis tubulosa
Hall. A report on the Shaler Memorial investigations of 1917 and
1918 was also prepared.

During the year large collections of Silurian Cephalopods and
of Cretaceous Bryozoa were loaned to Drs. A. F. Foerste and R. S.

larger part of our Lichadidae. Two advanced students, Messrs.
R. F. Webb and J. H. Bradley, Jr., prepared for publication
articles descriptive of fossils belonging to the Museum.

The accessions, in addition to those mentioned, have been as
follows: — donations — Messrs. S. W. Chase and Leverett Bradley,
Cretaceous fossils from France; Prof. G. H. Parker and Mr. John
H. Bradley, Jr., trilobites from British Columbia; Dr. A. F.
Foerste, Leperditiae from Topsfield, Mass.; the British Museum
(Natural History), through Dr. F. A. Bather, the cast of a speci-
men of Isotelus; M. Changanui, Dijon, France, through Prof.
A. C. Lane, six species, univalves from Pleistocene near Dijon,
R. V. Chamberlin, five drawers of fossils from Utah; by purchase—
four crustaceans from British Columbia; seven thin sections of
Ordovician fossils; by exchange — E. R. Cumings, University of
Indiana, two bags of young shells from Harrodsburg, Ind., Uni-
versity of Colorado, through N. E: A. Hinds, fifty-eight species of
Pennsylvanian fossils; Prof. W. H. Shidler, Miami University, Ox-
ford, Ohio, twelve species Ordovician fossils.

32 ANNUAL REPORT OF THE

REPORT ON THE GEOLOGICAL COLLECTIONS.
By R. W. SAyYLEs.

The installation of the unique collection of cave deposits from
Bisbee, Arizona, in the new hall case, was successfully accom-
plished. The dark hall and artificial lighting give a realistic effect
not attainable by sunlight. .

In January, the Curator studied the collection of microscopic
slides of slate and shale at the National Museum in Washington,
with the object of finding evidences of seasonal deposition. This
search resulted in the discovery of probable seasonal banding in
lowest Cambrian or latest Proterozoic times. In June, Mr. Allyn
C. Swinnerton, a graduate student, was sent to collect specimens
and make a field study of some of the slates examined in Washing-
ton. His findings corroborated the microscopic evidence noted
in the slides. Mr. Swinnerton visited several localities in south-
east Tennessee, in New York near Albany, and in western Vermont,
and the Cobalt, Ontario, region. The Curator takes this oppor-
tunity to express his gratitude to the geologists at Washington for
the willing help given him.

The months of February, March, and April, were spent in study-
ing the literature bearing on geologic climates.

Mr. Preston E. James gave a splendid slab of glaciated granite
from Rockport, Mass. The labels in the Museum have been
renewed.

The payments on account of the Museum are made by the Bursar of Harvard
College, on vouchers approved by the Director. The accounts are annually
examined by a committee of the Overseers. The only funds the incomes of
which are restricted, the Gray, the Humboldt, the Whitney, the Louis Cabot,
and the Alexander Agassiz Expedition Funds, are annually charged in an
analysis of the accounts, with vouchers, to the payment of which the incomes
are applicable.

The income of the Gray Fund can be applied to the purchase and mainte-
nance of collections, but not for salaries.

The income of the Humboldt Fund (about $400.) can be applied for the
benefit of one or more students of Natural History, either at the Museum, the
United States Fish Commission Station at Woods Hole, the Stations at Ber-
muda, or the Tortugas.

The income of the Whitney Funds can be applied for the care (binding) and
increase of the Whitney Library.

The income of the Louis Cabot Fund can be applied to the purchase of —

42 ANNUAL REPORT OF THE

APPENDIX A.
From THE WiLL or WILLIAM BREWSTER.

Fourth. My collection of mounted birds and of bird skins, nests and
eggs with the cases and cabinets that contain them and all my manuscripts,
catalogues of the birds, bird skins, nests and eggs, and my guns, collecting
pistols and various things appertaining to them, together with my oil painted
copy of Healey’s painting of Audubon, and my manuscript note books and
journals I give to the President and Fellows of Harvard College for the Museum
of Comparative Zoédlogy at Cambridge, imposing no conditions affecting this
bequest, but hereby expressing my desire that the collection be kept essentially
intact and the hope that both specimens and manuscripts may be so dealt
with as to render useful service to ornithologists, instead of lying unconsulted
and half forgotten as has sometimes happened to similar material deposited
in large museums. It is further my wish that free access, under such precau-
tionary rules as the institution may see fit to impose, be at all times afforded
to ornithologists who may wish to examine or study the specimens.

Fifth. Such of the printed books in my library as relate to natural history
I give as follows:— To the President and Fellows of Harvard College to be
added to the library of said Museum of Comparative Zoédlogy such as are
not duplicates of those in said Museum library at the time of my death * * *

Sixth (a) To the President and Fellows of Harvard College for the Museum
of Comparative Zoélogy at Cambridge, the sum of sixty thousand (60,000)
dollars, three quarters of the income thereof to be used exclusively for the
payment, or part payment, of the salary of a competent ornithologist, who
shall take charge of my collection hereinabove given to said Museum and the
remaining one-quarter to be used at the discretion of the Director of the
Museum for the increase of the collection by purchase, or for the renewal or
repair of the cases, or for the publication of matter contained in my manuscripts.

APPENDIX B.
Louis Acassiz TO RicHarD Buiss, JR.

Cambridge, May 7th, 1867.

Dear Sir,

I have duly received your note and take pleasure in answering it in a man-
ner which I trust may be satisfactory. Mr. Thayer’s liberality towards the
Museum and the students connected with it has hardly any limit. You may
be assured that if you answer my expectations you will want nothing that may
contribute to your progress. But in proportion as the facilities thus afforded
are complete, it becomes my duty to be careful how and on whom-they are

bestowed, as he allows me the most absolute control over their application.
My first care is therefore to make sure that the persons selected, under these
circumstances, are truly interested in the study of natural history and intend
to make it their life business. It is hardly worth my while to give my time to
young men who may after a few months turn their attention to other studies.
And the pursuit of natural history requires a most absolute devotion. More-
over it is no light affair and before a satisfactory result can be reached it takes
years of hard and uninterrupted studies. I expect therefore that you will
seriously examine yourself before you decide to come and satisfy yourself
that you are prepared to go through the ordeal of a severe training during
which all preconceived notions and selfish aspirations must be set aside to
make room for such impressions as are resulting from a-careful & faithful
examination of nature’s facts. It is very rarely the case that a student in my
department, even if he brings to the task a thorough college education, is fit
to pass an examination before he has been three years in the laboratory.
For all this time and more if necessary, Mr. Thayer will provide for all your
wants, provided no extravagances are indulged in. You would have a room
in the building adjoining the Museum, known as Zoological Hall.

Should you feel any misgiving upon reading the above, you may come for
a few weeks & see how the work suits you and give it up if you find it too
hard. I expect the students to be daily seven hours at their work in the labo-
ratory and otherwise to spend their time as becomes a student in reading
and making themselves generaly conversant with such collateral branches as
may advance their standing in their special pursuits.

Should you now decide to come, you may enter the laboratory at once and
the sooner you come the better, since the vacation approaches during which
I only spend part of my time in the Museum. Speaking of vacation I would
add, that special students who would make the study of Nat. Hist. their life
business are expected to employ the ordinary vacations, allowed the students
in the University, in the same manner as term time and only to absent them-
selves for such short periods as the care of health requires.

Respectfully yours,
L. Agassiz.
Richard Bliss, Jr., Esq.
