 . Form and proportions highly varial)le. Body usually elongate and 

 compressed, but sometimes deep and with the iwck elevated. Depth in 

 length about four to five times, but in some bighly developed males the 

 depth becomes two and two-thirds. The head is usually rather long and 

 pointed, being contained in the length about four and a half times. In 

 the deep-bodied males the snout may be rather short. Mouth oblique, mod- 

 erate or rather large, the maxillary attaining to a perpendicular to the front 

 of the eye. Teeth, 2-4-4-2, with the grinding surface developed. Dor-

This is one of our most beautiful fishes. It prefers clear streams. 

 Specimens taken by myself, at Winamac, about July 1, were in the breed- 

 ing stage. All the fins of the males were of a beautiful red, and the an- 

 terior parts of the body were covered with sharp tubercles. The females 

 were filled with spawn. Dr. Forbes found that this species eats small 

 diptera.
