This species is rlistingnishod from M. verecundiim Gilb. by the larger

The outlines of this form bear considerable resemblance to those of spe- 

 cies of Gaidropsarus and Lepidion. The body is elongate, compressed, 

 and slender backward ; it has a short cavity ; and head and body are cov- 

 ered with small scales. Mouth large; jaws nearly equal; teeth small, in 

 villiform bands on tlie jaws, absent from vomer and palatines. Four gills, a 

 slit behind the fourth. Seven brancliiostegal rays. No jiseudobranchiae. 

 No barbel. Gill rakers on the outside of the first arch numerous, elongate, 

 slender. Fins elongate ; two dorsals, hardly separate, anterior with eight 

 rays; ventrals narrow, of about seven rays; caudal distinct.

Much compressed and tapering to very narrow and slender posteriorly ; 

 body cavity in the anterior one-third of the length, extending far behind 

 the vent and the origin of the anal fin. Head comparatively large, two 

 ninths of the total length, four fifths as wide as deep, broad and rounded at 

 the snout ; crown longitudinally almost straight, strongly convex trans- 

 versely; chin wide, ascending forward. Snout large, broad, blunt, slightly 

 prominent above the nostrils, one and one fourth times as long as the eye. 

 Nostrils small, both near the upper portion of the eye, close together; ante- 

 rior much smaller and somewhat higher. Eye large, four fifths as long as 

 the snout, one fourth as long as the head, lateral, prominent. Mouth large, 

 cleft extending below two thirds of the eye and ri.sing considerably forward ; 

 maxillary reaching a vertical from the hind border of the orbit. Teeth in 

 villiform bands, on the jaws only ; bands wider on the upper jaws, narrow 

 on the lower. A slight prominence of the bone below the mandibular sym-
