By TAKLETON H. BEAN. 



Tbe Uuited States Natioual Museum has again received from Captain 

 Bendire a consignment of alcoholic fishes secured by him last summer 

 and fall. A large collection previously sent by the captain was only 

 partially examined and reported on in the summer of 1881*; the greater 

 portion of the fishes are yet to be studied. 



The lot just received includes eleven species, nearly all of which are 

 well represented by individuals, giving opportunity for comparison of 

 forms which are mostly rare in museums. Captain Bendire's field notes 

 are included in the remarks upon the species to which they apply. 



I think there is no reasonable doubt that the material thus brought 

 together will enable us to prove the identity of Coregonus Couesii with 

 C. WiUiamsonii, and to make, eventually, a consolidation of several spe- 

 cies of Apocope. 



The following is a list of the species : 



1. TJranidea marginata. 7. Apocope nnbila. 



2. Coregonus WilJiamsoniL 8. Mylochilus caurinus. 



3. Oncorhyncus chouicha. 9. Richardsonius balteatus. 



4. Oncorhynchus nerlca. 10. Lampetra tridentata. 



5. Acrochilus alutaceus. 11. Ammoccetes plumbea f 

 G. Rhinichthys transmontanus. 



1. Uranidea marginata Bean.
