FAMILY CYPK1NID.E. 



CARASSIUS AURATUS (Linnaeus). 



Eighteen specimens, 1. 80 mm. to 160 nun. D. lU, Iti-IT. A. Ill, 

 6-6. Head,3f; depth, 2f. 



CYPRINUS CARPIO (Linnaeus). 



Six specimens, 1. 70 mm, to 145 mm. 



ACHEILOGNATHUS IMBERBIS Giinther. 



Sixteen specimens, av^erage 1. 82 mm. D. II, 18. A. II, 10.^ Scales, 

 4-35-6. Pharyngeal teeth serrate; no barbels. There is quite a 

 prominent anal papilla, lying between the ventrals and usually equal- 

 ing them in length. 



TOXABRAMIS^' ARGENTIFER Abbott, new spaces. 



This genus apparently closely resem])U>s the two genera Hem'wul- 

 tet^ella^ Warpachowski,'' and Ilemicultci-, Bleeker,* but in the latter 

 the pharyngeal teeth are in three series, and in the former there is no 

 thickened second dorsal spine and the abdomen is not trenchant ante- 

 riorly. However, many of the immerous genera in this family appear 

 to rest upon very weak foundations, and it is likely that a com- 

 parative and critical study of the material that recent years have 

 afforded will reduce the number recognized.
