316 DEEP SEA FISHES. 



Pores of the forward part of the head elongate. Gill openings crescentic, 

 upper angle at the lower edge of the base of the pectoral, twice the width 

 of the space separating them on the chest, width equal two filths of the 

 length of the snout. 



Dorsal more developed than the anal, originating one diameter of the 

 orbit forward of a vertical from the base of the pectoral. Anal narrow, 

 originating about sixty-five rays backward from t!ie dorsal origin. Caudal 

 narrow, pointed, of about seven rays in the present specimen. Pectorals 

 narrow, low on the side, acuminate, occasionally absent, commonly of twelve 

 rays, sometimes of thirteen, in length equal to one half of the distance from 

 the snout to the end of the maxillary, two thirds as long as the snout. 



Lateral line distinct, median, continuous ; pores on tlie anterior portions 

 s'ubround, those toward the caudal becoming elongate or confluent into an 

 open groove. Cephalic pores larger, from the postorbital region forward 

 elongate. No scales. An air bladder. Vertebras 39 + 134. Males smaller; 

 females with caudal region shorter, less than three times head or trunk. 



Brown tinged with red; pores, mouth, and edges of dorsal and anal, whit- 

 ish to reddish ; pectorals red with more or less of blackish at their bases. 

 Young lighter in color. 



Distinguished from ^Y. atranus Gilb., by the equal length of head and 

 trunk, by longer pectorals, and by the coloration. The proportions are 

 similar to those of X. trucidans Ale, but the coloration differs greatly.
