The dentition of this species varies greatly, especially so if we con- 

 sider Neetroplus carpintus Jordan and Snyder identical with it. In 

 my account of the genus Neetroplus (Field Mus. Pub., Zool. Ser., V., 

 221) I called attention to the fact that the incisor teeth of N. carpintis 

 were not always evident. Owing to the variation in color and form 

 as well as in dentition, I am inclined to believe Mr. Regan is coiTect 

 in combining these two supposed species. The smallest specimens 

 (50 mm.) usually have pointed conical teeth. Other sjiecimcns (100 

 to 150 mm.) may have very few incisor-like teeth while in others of 

 the same size these teeth are quite evident. For fishes of the length
