COMPARATIVE ZOOLOGY. [Mar. 



of the hard parts of different genera, from spider-crabs down 

 to the horse-shoe. I was assisted in this work by Miss Gush- 

 ing and Mr. Birge. I intend to add to this series dissections 

 illustrating the internal organs. I am now working upon the 

 fossil Crustacea. A representative series will be put on exhi- 

 bition, and the whole collection, it is hoped, placed in a con- 

 dition of permanent safety.

Selachians, — The anatomical work laid out by Professor 

 Agassiz occupied the earlier portion of the year. Afterward 

 the entire collection received new alcohol, and much of it new 

 labels. To clear the room for the use of the college, the 

 anatomical preparations were removed to the room occupied 

 by the fishes ; about one-fourth of the sharks and skates were 

 placed on exhibition, and the balance, changed from the bar- 

 rels and kegs, were carried to the cellar. The number of 

 specimens identified and catalogued during the year was about 

 five hundred. This collection fills two large tanks and thirty- 

 nine of the larger-sized copper cans, besides a great number 

 of jars ; it is in good condition. 



Reptiles, — The reptiles have been sorted, catalogued, pro- 

 vided with fresh alcohol and placed in copper. The space 

 allotted to the reptilia, in the exhibition-rooms, has been 

 filled. In addition to the regular Museum catalogue, a second 

 has been made on cards, similar to those in use in the libraries, 

 for the identified specimens of each of the selachians, reptiles 

 and batrachians, by means of which the geographical distri- 

 bution, the genera of the family or species of the genus rep- 

 resented in the collection, the whole number of specimens 

 and the position in the Museum can be readily ascertained. 



Donations have been received from Col. Beddome, Rev. 

 M. M. Carleton, Prof. Heller, Prof. Shaler, Mr. Whorf and 

 others. 



About thirty-three hundred articles were catalogued ; with 

 few exceptions, in good order. 



Batrachians, — More than three thousand have been cata-
