380. S. pulcBier (Grd.) Jor. & Gill). 



Body rather slender, little compressed. Head rather long and pointed. 

 Mouth oblique, terminal, the jaws about equal, the maxillary barely 

 reaching the front of eye. Scales moderate. Lateral line decurved. 

 Fins large. Dorsal behind ventrals, its tip when depressed reaching 

 the posterior base of the anal. Pectorals nearly reaching ventrals. 

 Coloration brilliant; dusky above; sides and belly golden (red in life?); 

 sides with a vague dusky band. Head 3|; depth 4J. D. 8; A. 8; 

 scales 13-G3-7; teeth 1, 4-4, 1, without grinding surface. L. 6 inches. 

 Chihuahua Eiver. A handsome species, resembling JSquaUns cceruleus, 

 but with the fins larger and the number of teeth different. Although 

 Girard i^laces this fish among the Tigomcv with grinding surface on the 

 teeth, we are unable to find such surface on his typical specimens. 

 All that we have examined have the teeth sharp, and 1, 4-4, 1. If this 

 dentition is constant, it may be necessary to refer 8. pulcher to a differ- 

 ent genus.
