The coloration of these specimens is various and in general corre- 

 sponds with the description given by Giinther. Agassiz's figure repre- 

 sents a fish ornamented with fewer and larger spots than in these 

 Florida specimens, which show the spots very closely contiguous, espe- 

 cially on the head. Some of these specimens show narrow^ longitudinal 

 brown lines upon the throat and posterior part of the head below the 

 branchial opening. The markings on the dorsal fin are also somewhat, 

 different from any heretofore described. We observe a regularlj" undu- 

 lating line of white about as wide as the pupil of the eye, the upper 

 undulations extendiug to the edges of the fin ; between these undula- 

 tions are sub-triangular spots of blackish browu, which together form an 

 interrupted black margin to the fin. These markings, and indeed the 

 general appearance of the fish, are perhaps best represented bj' Girard's 

 figure, which, however, fails to indicate the white undulating line 

 already mentioned. 



The Museum has also a bottle, No. 5,997, containing old and young 

 specimens of this species from Cedar Keys, Florida. 



We have examined a specimen, apparently of this species, catalogued 

 "No. 7,004, St. Joseph's Island, Texas, Geo. Wiirdemann," which we 

 believe to be the original type of Girard's Neonmrwna nigromarginata.
