NEW PHILIPPINE FISHES FOWLER 115 



over greater part of its upper section gray black, edge pale or whit- 

 ish all around, and outer face of fin edge of each ray narrowly whit- 

 ish. Three detached rays and front margin of ventral broadly 

 whitish. 



Type.—V.S.^M. no. 98869. (2223.) D. 5519. Point Tagolo 

 Ligiit, S. 71° W., 8.7 miles (lat. 8°47' N., long. 123°31'15" E.), 

 vicinity of northern Mindanao. In 182 fathoms. August 9, 1909. 

 Length 150 mm. 



Reinarhs. — Apparently related to Pterygotrigla ryiihyuensis Mat- 

 subara and Hiyama 1932, Ryukyu Islands, based on a specimen 260 

 mm long. That species differs noticeably in its much broader and 

 shorter rostral spines, more narrow predorsal plate, absence of the 

 postero-supraorbital spine, shorter and less divergent suprascapular 

 spines and shorter pectoral,

DIXIPHISTOPS, new genus 



Type. — Dixiphistops megalops^ new species. 



Body elongately ovoid, well compressed. Head deep, moderate, 

 compressed. Snout moderate, depressed, much shorter than rest of 

 head. Eye very large, well impinging on upper profile, center little 

 behind middle in head length measured from snout tip. Mouth mod- 

 erate, terminal, low, nearly horizontal. Maxillary reaches opposite 

 front of eye, well expanded behind and slips below preorbital. Inter- 

 orbital deeply concave. Nostrils small, well separate and hind pair 

 midway in snout. Gill rakers long, lanceolate. Gill opening wide, 

 extends forward about last fourth in snout. Head largely with sur- 

 faces of bones finely rugose striate. Each side of snout a long, flat, 

 slender, acuminate spine, at least % rest of head. Small pair of 

 spines between posterior nostrils. Ridge of suborbital stay well 

 marked, entire or without spines. Strong depressed spine back from 

 each side of occiput. Opercular spine small. Rather long, slender, 

 humeral spine. Each side of spinous dorsal 8 rugose bony bucklers, 

 besides one close before fin. No bony bucklers along base of soft 

 dorsal, though each ray with a small, short basal spine each side. 

 Lateral line complete, high along side, composed of moderate tubes. 

 Scales minute, rather irregular, and firmly adherent. Dorsal spines 

 7, slender, fin % of soft dorsal. Anal opposite soft dorsal, similar. 

 Caudal little emarginate. Pectoral moderate, reaches half way to 

 caudal base ; fin in 2 sections, with lowest rays of upper section grad- 

 uated short ; uppermost ray of low^er section little longer than upper 

 section of fin. Ventral short, reaches vent.
