of Trichosoma, so far as I can determine. There are no teeth on 

 the hyal bones, the maxillary is more produced, the eye larger, and 

 there are no punctulations on lower side of head. 



I take pleasure in naming this species for Miss Fielde.

Body regularly tapering from dorsal to tip of caudal, snout pro- 

 jecting half its length beyond lower jaw, eye equal to or very slightly 

 less than snout. Mandible If in head, maxillary to below root of 

 pectoral. Teeth on maxillary becoming larger and farther apart 

 posteriorly, but somewhat worn off on the free portion. Teeth of 

 lower jaw in a single series, imbedded in the gums; two small, 

 widely separated patches of strong teeth on vomer, a single row on 

 palatines, none on hyoid arch. Base of dorsal high anteriorly, a 

 rudimentary free spine in front, the last rays short, so that their tips 

 form an almost vertical line when the fin is extended. Anal low, 

 covered with large scales, rays crowded posteriorly, its origin under 

 tip of depressed dorsal. Pectoral filaments seven, their tips reaching 

 about to eighth anal ray, the non-filamentous rays reaching about to 

 middle of depressed ventrals. Ventrals inserted slightly in advance 

 of dorsal, their length scarcely longer than base of dorsal. Base of 

 caudal oblique, upper lobe of fin longer. Sixteen spinous scutes on 

 abdomen.
