BULLETIN OF THE IfNITED STATES FISH COMMISSION. 



Scales fallfii, with the exception of 2 or 3 along the course of the lateral line, which runs along 

 middle of sides, and describes anteriorly a convex curve above pectoral tin; scales like those observed 

 in other species of the genus, without spines, marked with very numerous stria', which are roughened 

 by a series of minute prominences; they covered entire body, liut their presence on head can not be 

 verified, owing to the condition of the type.

Fig. 258. — Mrlanohrinirlins iiiifrnnimu (Jilhfrt, new .species. Type. 



Color, head and fins li,i;ht grayish, margins nf the' scale pouches dusky; head light grayish on top 

 and sides, except opercle and gill-meinbranes, which are black; belly, gill and gnlar membranes, and 

 the inner lining of cheeks ami opercles black; lireast, shoulder girdle, isthmus, lips, and lining o( 

 mouth dark brownish; peritoneum dusky. 



A single sjjecimen was obtaineil. 



Chalinura ctenomelas (filbert ct t'ramer. 



This a very abundant species in depths of L'ul) to 3.50 fathoms. 



As seen from above, the terminal portion of snout is broadly triangular, tapering rapidly forward 

 to the angular tip, which is aljout on level of middle of eye; maxillary reaching to or slightly beyond 

 hinder margin of orbit, its length slightly less than half length of head; outer series of enlarged teeth 

 in upper jaw weakly arrow-shaped, the shape most apjiarent in the lateral teeth of the series; the 

 villiform mandibular teeth are in 3 irregular series and have distinctly arrow-shaped tips, as have 

 also those of the mandibular band, which are arrangt'd in 2 irregular series; angle of preopercle 

 produced, the posterior margin running obliquely upward and forwar<l, incurved al)Ove the angle; 

 spinelets on scales not arranged in longitudinal series, but in definite oblifjue series (quincunx order). 



A small naked ])it lying between biases of ventral fins is separateil by a narrow liand of scales from 

 the scaleless area surrounding anal oj>ening; in some si)ecimens the 2 areas seem to be connected by a 

 narrow naked line, in others by a broader naketl streak, but it is considered probable that tln'se con- 

 ditions were due to the loss of scales; distance between dorsals varying from tn ice to nearly thrice the 

 base of anterior dorsal; mouth-cavitj' white, black only in extreme posterior part; gill-ca\'ity largely 

 white anteriorly, black above gills, on opercular region, and lining of shoulder-girdle.
