475 



This species is close to Coelorhynchus commutahilis Smith and Rad- 

 chffe, from the Phihpphies/ differmg iii size of eye, character of spine 

 of first dorsal, barbel, and length of snout. From Coelorhynchus 

 canus Garman, it differs in the position of the pectorals, insertion of 

 dorsal, anal and ventral fins, length of maxillary, and in character of 

 scales.

COELORHYNCHUS PATAGONIAE Gilbert and Thompson. 

 Plate 6, fig. 2. 



Type, a small specimen, 125 mm. in total length, from Albatross 

 station 2784, between Wellington Island and the mainland on the 

 west coast of Patagonia, in 194 fathoms. ±t is Cat. No. 76862, 

 U.S.N.M. 



Head 4| in total; U in length to anus; depth 6i in total, 2f in 

 length to anus; orbit 2^ in head; interorbital width 4f; snout 3|; 

 maxillary 3§; mandible SJ; distance premaxillary to tip of snout 3; 

 D. II, 9-63; A. 71; P. 17; V. 7; brancliiostegals 6. 



Snout not much produced, equal to two-thirds orbital diameter 

 and-the distance from tip of snout to premaxillaries; a strong 

 suborbital ridge from tip of snout to produced sharp angle of 

 preopercle, which covers the interopercle; suborbital ridge double 

 backward from below nares; a broad low median dorsal ridge on 

 snout ending above anterior edges of orbits; supraocular ridge but 

 Httle evident, represented by a row of shghtly enlarged plates; a 

 pair of ridges from interorbital space diverging somewhat at occiput 

 mitil their terminations are a tliird farther apart than the beginning; 

 a low ridge runs from upper border of eye along upper margin of 

 opercle, with a larger ridge between it and occipital ridges; lower 

 surface of head and jaws naked and unarmed save for the spur 

 on mandible at articulation.
