Genus UrantwEA Dekay. 
The Blobs.

its length; snout 324; eye 4; maxillary 214 ; interorbital space 7; 
least depth of caudal peduncle 4%; pectoral 1%; ventral 1%. 
Body rather slender, fusiform, compressed. Head moderately 
broad, convex above, and flattened below. Snout convex, 
rounded. Eye ellipsoid, well anterior and superior. Mouth

teriorly. Preopercle spine broad. Opercle ending in concealed 
spine. Gill-rakers a few short stumpy tubercles. Skin smooth. 
Origin of spinous dorsal opposite that of pectoral. Origin of 
rayed dorsal a little nearer base of caudal than tip of snout, and 
its base twice that of spinous dorsal. Anal inserted a little pos- 
terior and tips of radii free or edge of fin notched. Caudal 
rounded. Pectoral large, reaching a little beyond anal, and radi 
of lower half of fin graduated down. forwards with their tips
