64 MUSEUM OF COMPARATIVE ZOOLOGY. [Feb. 



valuable of these additions are the collection of European insects 

 purchased from Dr. Imhoff with the Gray Fund, the insects of Cali- 

 fornia, Acapulco, and Panama, collected by my son, and the collection 

 made on the Saskatchawan River by Mr. Scudder, and also the 

 insects collected at Woburn by Mr. Shute, and in Maryland by 

 Mr. R. Stratton. 



To the class of Crustacea, 3,641 specimens have been added, repre- 

 senting 496 species, the most important of which are those collected 

 at the Sandwich Islands by Mr. Garret, at Hobart Town by Mr. Rob- 

 ertson, on the Pacific Coast of North America by my son, and in 

 Florida by Mr. Theodore Lyman. 



Since the representatives of the class of Annelids and Helminths 

 have not yet been arranged at all, I am unable to say what additions 

 have been made to these classes. 



I 



The Mollusks have received extraordinary additions amounting to 

 not less than 50,000 specimens, representing 3,000 species at least. 

 An invaluable addition consists of a large collection presented by the 

 Smithsonian Institution, besides a -large collection purchased from Mr. 

 John Bartlett, and another from Mr. E. S. Morse, and also the speci- 

 mens collected by my son on the west coast of North America, and 

 at the Sandwich Islands by Mr. Garret. 



The class of Echinoderms has been increased by 3,500 specimens, 

 representing 92 species, the most valuable being those collected at 

 Acapulco by Mr. Van Brunt, at Zanzibar by Mr. Cheney, at Fayal by 

 Miss Dabney, at the Sandwich Islands by Mr. Garret, and on the west 

 coast of our continent by my son, besides which very valuable speci- 

 mens have been collected on our own coast by the students of the 

 Museum. By exchange we have also obtained very important types 

 of this class from the Museum at Copenhagen, and from the Smith- 

 sonian Institution. 



To the class of Corals have been added 2,130 specimens, represent- 

 ing 666 species. The most extensive addition to this class is a collec- 

 tion of fossil corals bought with the Gray Fund, next to this, the 

 collection of corals from the East Indies by Captain Putnam, and 

 besides these, the specimens collected by my son on the Pacific Coast. 

 I may add that Mr. T. G. Cary of San Francisco has largely contrib- 

 uted to the invoices made by my son, from the Pacific Ocean, and 

 that there is still unopened a large invoice from him.
