obsolete lengthwise ridges becoming confluent at their fusion below 

 dorsal, and resulting single lateral keel extends along each side to 

 caudal. Lower edges of head and edges of rostrum with elongated 

 clusters of spinules, all rather distinct and larger than elsewhere. 

 Scutes 22 behind dorsal. Belly with single median series of plates 

 between lateral series. Between pectoral bases 4 scutes. L. 1, 

 developed only as series of about 14 pores in sutures, one to each, of 

 costal plates. 



Dorsal inserted nearer snout tip than caudal base by length of 

 snout, spine slender, minutely spinulose, longest of radii. Anal

inserted slightly behind dorsal origin, otherwise similar to dorsal. 

 Caudal moderate, deeply emarginate, and uppermost and lower- 

 most ray each enlarged and produced into slender filaments but 

 little less than length of trunk. Pectoral with flexible, slender, 

 minutely spinulose spine, longer than other radii, and not quite 

 reaching ventral origin. Ventral inserted about midway between 

 pectoral and anal origins, spine moderately robust and minutely 

 spinulose, longer than other rays and reaches f to anal origin. Vent 

 placed midway between ventral and anal origins. 



Color in alcohol pale gray-brown generally, abdomen, belly and 

 lower surface of head more or less whitish. Rostrum brownish above 

 and below. Iris slaty. Along side of head narrow obscure brownish
