 head; maxillary, 4; snout, 5; dorsal, (39; anal, 50. 



Body moderately slender, the upper anterior outline concave oppo- 

 site front of eye, and the snout somewhat produced, but without an 

 abrupt sharp notch. Upper 63^6 slightly more posterior than lower. 

 Interorbital space flat, rather narrow, and not elevated; its entire
