12 Twenty-sixth Report on the State Museum. 



order of arrangement adopted by Mr. Carpenter has been in every 

 respect preserved, the collection being simply adapted to the larger 

 case. 



The collection of New York Mollusca, which (exclusive of addi- 

 tional species contained in the suite below mentioned) embraces 

 about one hundred and seventy of marine, land and fresh-water spe- 

 cies, has been transferred from drawers beneath the Gould shells, and 

 placed in the new case at the west end of the room. This case is 

 intended eventually for the Invertebrata of New York ; at present 

 some of the Smithsonian contributions of shells will be arranged in 

 one portion of it. 



The collection of Long Island Mollusca, types of the list of Messrs. 

 Smith and Prime, given in Yol. IX of " Annals of the Lyceum of 

 Natural History of New York," the donation of which has been 

 mentioned in the last report, has also been arranged in this case, 

 where, in accordance with the very proper request of the donors^ 

 it will be kept as a distinct collection. The further contribution by 

 these gentlemen of additional species embraced in their list, an 

 acknowledgment of which appears in the present report, has also 

 been incorporated with the above,, thus increasing the number of 

 species to one hundred and twenty -one. I take pleasure in announc- 

 ing the promise of a similar collection of the Mollusca of Staten 

 Island, by Mr. Sanderson Smith, typical of his lists in the Annals of 

 the Lyceum. 



A small number of New York Crustacea, taken from duplicate 

 alcoholic specimens of the Museum, with a few species recently 

 obtained, have been treated with preservative solutions, which it is 

 believed will permit of their permanent display as dry specimens. 

 In this condition they have been placed in trays in the case of Inver- 

 tebrates, where their forms can be more easily comprehended than 

 when seen through the refraction of a fluid medium, and in the 

 unnatural position assumed in glass jars. 



Some Lepidopterous larvse have been prepared as a commencement 

 of a representation of the class of Insects ; also a few of the Myrio- 

 poda ; but these have not yet been placed on exhibition. 



In the upright portion of the Invertebrate case, the alcoholic col- 

 lection of New York Fishes, removed from wall cases at the south 

 corner of the room, has been temporarily arranged. Its classification 

 is that adopted by De Kay in his Zoology of New York. In this 

 case are also placed some fishes received from the Smithsonian Insti-
