12 TWENTY-SEVENTH REPORT ON THE STATE MUSEUM. 



male and female. These have been received from Mr. Thomas 

 Moore, of the Derby Free Museum of Liverpool, Eng., in 

 return for objects sent him by J. W. and C. E. Hall, and by 

 them presented to the museum. 



The aquarium, formerly occupying the space between the 

 third wall-case and the Archaeological collections, has been 

 removed to the basement of the building, and the space fully 

 utilized by occupying it with the skeletons of Elk, Moose and 

 Buffalo ; which, however, are scarcely well accommodated in 

 this position. 



Having no space on this floor for the jaw and other bones 

 of the Whale in their proper zoological relations, we have 

 mounted them over the doorway in the entrance hall of the 

 Museum, as being the only available space at present at our 

 disposal. The jaw, as it now stands, measures 17 ft. 4^- inches ; 

 with the missing parts of the skull it would measure over 

 eighteen feet. 



Some additions have been made to the New York Inverte- 

 brata. From the material collected during the past year by 

 Mr. C. E. Hall, (a very small portion of which has yet been pre- 

 pared for exhibition), there have been added to the Crustacea 

 a fine series of Limulus Polyphemus at different stages of 

 growth, and a dissection of a large individual of the same. 



The Insecta are represented in the arrangement of one hun- 

 dred and thirty-three trays, containing specimens of the earlier 

 stages of insects, — eggs, larvae, and pupae, together with 

 cocoons, galls, and various parasites. A list of these additions 

 will be found under the proper head in this report. 



The Mollttscan Collections. 



At the time of the receipt of the Gould collection of Mol- 

 lusca, in 1863, two of the boxes labeled as containing Type 

 specimens were set aside and left unopened, as there was no 

 suitable place for their reception. For convenience of refer 

 ence, it was thought better to keep these distinct from the 

 main collection ; and as a measure of prudence, on account 

 of their value as types, that they should not be exposed to 

 the depredations with which our cases, although guarded by 

 locks and screws, have repeatedly been visited. 



During the past year, these boxes have been unpacked ; 

 and the specimens, with about fifty other species (taken
