PHILIPPINE MACROUROID FISHES — GILBERT AND HUBBS. 393 



e 2 . Band of teeth in upper jaw expanded posteriorly, its greatest 

 width being contained from 1£ to 1§ times in the least width 

 of bony suborbital region ; color darker ; head more cavernous ; 



pyloric caeca 61 to 75 denUculatns (East Indies). 



d 2 . Teeth small, but readily distinguishable by the unaided eye; band 

 of teeth in the upper jaw narrow, its greatest width 2.0 to 2.4 in 

 bony suborbital region ; filamentous rays longer, the dorsal spine 

 being more than twice as long as the head ; pyloric caeca 24 to 



29 magnifilis (Jolo Sea, Philippines). 



c 3 . Interorbital 1.0 to 1.23 in orbit; gill-cavity wholly black, as in the 

 following species ; gular membrane black ; ventral fin with 8 rays. 



introniger (East Indies). 

 & 2 . Gill-rakers on lower limb of outer arch 26 or 27, long and pointed ; 

 pectoral rays 17 to 20 ; interorbital space nearly as wide as the orbit ; 

 pyloric caeca 12 or more ; gular membrane black ; teeth readily dis- 

 tinguished by unaided eye. 



f. Ventral rays constantly 8 ; pseudobranchiae present in speci- 

 mens nearly as large as the type of melanoptems ; scapular 

 foramen on suture between hypercoracoid and hypocoracoid. 

 multifilis (East Indies to Japan). 

 f. Ventrals 9-rayed in type ; 1 no pseudobranchiae in type ; scapu- 

 lar foramen wholly within the hypercoracoid. 



melanopterus (Hawaiian Islands). 

 o 3 . Gill-rakers on lower limb of outer arch 30 to 35 (30 to 33 counted by us, 

 35 given in original description) ; gill-rakers long and slender, sharply 

 pointed; pectoral rays 15 (13 given in original description); inter- 

 orbital space decidely narrower than the orbit; teeth relatively coarse, 

 approaching those of Bathygadus; pyloric caeca S; gular membrane 

 black longi filis (Western Atlantic). 



6. GADOMUS DENTICULATUS, new species. 



Bathygadus longifilis Weber, Fische der Si&Ofira-Expedition, 1913, p. 171. 



Type-specimen. — Cat. No. 78207, U.S.N.M., 307 mm. long to end 

 of regenerated pseudocaudal, 112 mm. long to anus, dredged by the 

 Albatross off northern Mindanao, at a depth of 220 fathoms, at sta- 

 tion 5505. 



At each of the following stations a single paratype was dredged, 

 with the exception of station 5198, where two were obtained :

1 Ventral 8-rayed in a small Hawaiian specimen perhaps distinct from B. melanoptems, 

 having also a wider interorbital space, etc. (See Gilbert, Bull. U. S. Fish Comm., 1903 

 (1905), sec. 2, p. 659.)
