586 APPENDIX. 



M. Duvaucel, \vho continues his researches in India, has just sent us 

 the skeleton of a very large elephant, a gangetic dolphin more than 6 feet 

 long, and a great number of birds, amongst which forty-three*species 

 are unknown in the cabinet ; we expect from him a collection of fishes 

 amounting to five hundred species and two thousand individuals. 



We have received from M. Lesueur the greater number of the fishes 

 and mollusca described by him in the Journal of Sciences of Philadel- 

 phia; and from M. Milbert, some fishes taken in the lakes of the United 

 States, and which were unknown to us. 



Lastly, M. Dussumier, on his return from India, gave us a gazelle of 

 Bassora, a species of dolphin, and twenty-eight species of birds not in 

 the cabinet.
