MUSEUM OF COMPARATIVE ZOOLOGY. 5 



was purchased for the Museum through Mr. Eastman, and forms 

 the subject of one of the Bulletins issued during the past year. 



The Museum has, as in former years, provided the room for a 

 great part of the instruction in Geology and Zoology given to the 

 students of Radcliffe College, as well as to the large classes in the 

 Summer School of Geology. 



It seems only reasonable that some provision should be made 

 for the use of the rooms so occupied, as the Museum has no 

 source of income to meet the ever increasing demands made 

 upon it by the policy of the University in granting the facilities 

 of the Museum to persons who in no way promote its material 

 welfare. 



The increase of the Library by purchase, gift, and exchange has 

 been somewhat larger than in former years. The Library now 

 numbers nearly 32,000 volumes. Among the valuable additions 

 to it I may mention some volumes of pamphlets on Land Shells, 

 collected by Mr. William G. Binney, and a number of volumes 

 from the Library of the late Colonel Theodore Lyman. 



The Reports on the " Albatross" Expedition of 1891 are pro- 

 gressing favorably. Mr. Westergren has completed the Plates to 

 accompany the Report on Fishes, and Mr. Garman has the text 

 well advanced. The Report on the Ophiuridse, by Messrs. Liitken 

 and Mortensen, is in the press. 



The Report on the Acalephs, by Dr. Otto Maas, has been pub- 

 lished as No. 1 of Vol. XXIII. of the Memoirs. Of the Bulletin, 

 Vol. XXXI. has been published during the past year, and two 

 numbers of Vol. XXIII., and seven numbers of Vol. XXXII. 

 They contain six numbers from the Zoological Laboratory in 

 charge of Dr. Mark, two papers by Mr. Eastman, and two by 

 Dr. Woodworth. 



The Isopods of the " Albatross " Expedition, by Dr. Hansen, 

 a Preliminary Report on the Echini of the same Expedition, by 

 myself, as well as papers on Dactylometra and on Australian 

 Medusae in conjunction with Dr. A. G. Mayer, and a Report on 

 my Expedition to the Great Barrier Reef of Australia. 



In connection with the " Blake " explorations, I have published 

 an interesting paper by Prof. R. T. Hill, on the Geological His- 

 tory of the Isthmus of Panama, and Professor Bouvier and Dr. 

 Fischer have completed a memoir on the Pleurotomaria dredged 

 by the " Hassler " off Barbados.
