included; maxillary 1.78, extending beyond vertical from posterior 

 margin of eye for a distance equal to about one-half diameter of 

 pupil; mandibular barbel 2.15 in head, very long and slender; teeth 

 small, villiform in narrow bands, a toothless space at tip of upper jaw 

 about 0.4 of diameter of pupil in mdth; gill membranes forming a 

 free fold across the isthmus; no traces of pseudobranchiae discernible; 

 scales large, deciduous, 5 rows from last dorsal ray to and including 

 lateral line; middle of belly between vent and ventrals naked. 



Tip of snout to origin of dorsal 5 in total length; first dorsal spine 

 minute, second 1.37 in head, longer than adjacent soft rays; inter- 

 dorsal space 6.35 in total length; second dorsal low; tip of snout to 

 origin of anal 3.10, anal rays much better developed than those of 

 second dorsal; tip of snout to origin of ventral 5; outer ventral ray 

 4.80 in total length, long, filamentous; pectoral 1.71 in head. 



Color in alcohol: Ground eolor, ochraceous-bufF; region below 

 middle line of side with silvery reflections; region around and below 

 the first dorsal dusky; snout, angle of mouth, and a narrow line 

 along mandible whitish; roof of mouth, suborbital, cheek and pre- 

 opercle silvery; opercle, under side of head and body blackish, with 

 silvery reflections ; a striated area above ventral base extending back- 

 ward on median line of belly to vent; vertical fins brownish; a black, 

 spot at base of each ray of second dorsal and anal; paired fins dusky, 

 black at base. 



Type.— Csit. No. 72928, U.S.N.M., 21.6 cm. in length, taken with 

 a beam trawl at station 5459 (lat. 13° 10' 21'' N.; long. 123° 59' 54" 

 E.), off southeastern Luzon, at a depth of 201 fathoms. 



This species resembles H. longiharhis Giinther, and may prove to 

 be identical with it. In the Philippine species the snout and maxil- 

 lary are longer and the eye smaller than in Giinther's figure, and there 

 are more dorsal and pectoral rays. It differs from H. longipes in 

 having a well developed barbel, longer snout, slightly narrower inter- 

 orbital, more rays in the second dorsal and anal, and the rays adjacent 

 to outer ventral ray shorter. 



Genus MACROURUS Bloch. 



Some of the species included in the present genus possess characters 

 showing relationship to the genus Coryphse.noides, but the intergra- 

 dation of characters among the species is so gradual that we have 

 failed to discover any satisfactory line of separation. The conten- 

 tion of Garman ^ that the generic term Coryphsenoides based on C. 

 rupestris of Gunner (1765) should supersede Macrourus of Bloch (1787) 

 seems well founded. The retention of the generic name Macrourus 

 is provisional.
