406 ADDENDA. 



fin; the anal is similarly colored to the dorsal, but 

 fainter, and the ventrals are dusky; A. I, 11. Southern 

 Illinois. 



On page 284, after jj. LYTHRUKUS, add : 



u. Teeth without masticatory surface, their edges always 

 serrate CYPBINBLLA, 8 (b). 



On page 296, before Notropis, add : 



8. (b) CYPRINELLA, Girard. 



1. C. forbesi, Jordan. FORBES' RED-FISH. Body 

 short, very deep, much compressed, the depth 3 in 

 length; color in life chiefly red, a violet crescent behind 

 opercle; fins plain red; head and caudal peduncle pro- 

 fusely tuberculate; A. I. 8; lat. 1. 35; teeth 4 4. South- 

 ern Illinois, an elegant little fish. 



On page 296-7, for Notropis dilectus, 2?. rubellus, and 

 N. dinemus, substitute Notropis atherinoides^ Raf. I 

 now think it impossible to distinguish these "species," 

 and I adopt for them the oldest specific name applied to 

 any of them. 



On pages 309 and 311, for Lagochila, Jordan & Bray- 

 ton, read QUASSILABIA, Jordan & Brayton. The name 

 Lagochila may be considered pre- occupied in Con- 

 chology. The species, Q. lacera, has lately been taken 

 in Ohio by J. H. Klippart. 



On page 323, omit Ichthyobus cyanellus, I. rauchii^ 

 and I. ischyrus. I am now convinced that these sup- 

 posed species are merely the young of I. lubalus. 



On page 323, for Bubalichthys niger^ read J3. urus, 

 Agassiz.
