NK\\' SPECIES OF PHILIPPINE FISHES. f).";? 



iNamed for Doctor Boulenger of the British Museum whose work on 

 Palawan fishes I have found of great assistance. 

 Gnatholepis davaoensis Sfale, sp. iiov. 



Head 3.75; depth t.V'O; dorsal VI, l":!; anal 11; seales about -36, in 

 lateral series; cheek and opercle sealed; eye 3.75 in head; snout 3.75; 

 interorbital a mere ridge; muxillar}' 3.85, ending on a line with anterior 

 margin of eye; mandible 'L 



Upper and lower outlines of body about evenly and equally curved, 

 depth of caudal peduncle -2 in head, its length 1.25 in head. Head rather 

 bluntly rounded, the mouth oblique, jaws equal, tongue strongly bilobed, 

 teeth in upper jaw in several series, the outer one being enlarged curved 

 canines. Teeth of lower jaw in two series, the outer one of curved project- 

 ing canines, a large recurved canine on each side. Xo barbules, margin 

 of preopercle entire. Xo filamentous pectoral rays. No mucous cirri. 



The body and head, except snout and chin, are fully scaled, the scales 

 being large, thin and smooth, three rows on cheeks. 



Origin of spinous dorsal, midway between tip of snout and base of 

 fifth dorsal ray, the longest spine 1.30 in head, about equal to longest 

 ray. Caudal rounded, a fourth longer than head. Origin of anal 

 is midway between end of caudal vertebra and angle of mouth, being on 

 a line with the second dorsal ray, its longest ray equal to head. N'entrals 

 very long, equal to caudal, their tips reaching to anal, their origin much 

 nearer tip of snout than to anal, being directly below the base of the 

 pectoral. Pectorals equal to head. 



Color dull yellowish gray with 6 dusky blotches along sides, three 

 or four distinct black dots at base of caudal, a black band from eye 

 to middle of throat, some scattered black specks over body and in- 

 distinct indication of some dusky bars over back. Spinous dorsal grayish 

 with several scattered dusky spots and ten black dots on lower part 

 of fin. Soft dorsal grayish, anterior rays with slight indications of 

 darker cross bars. Caudal grayish with numerous indistinct brownish 

 dots and several larger distinct black spots on lower half of fin. Anal 

 is most peeuliarl)' colored with round black and white spots alternating 

 as on a checker board. Ventral grayish with a black margin, pectorals 

 grayish. 



Type is No. 38o,S from Samal Island, Gulf of Davao, Mindanao, P. I. 

 Length, 45 millimeters. 



This may be identical with the fish called G. deltoides by Jordan 

 and Seale in Pishes of Samoa, but their specimens differ decidedly 

 from the type of G. deltoides in lacking the characteristic markings 

 which were present in all our 18 specimens from Guam, and in our 

 Philippine specimens also, which are, however, different from the, Guam 

 form, therefore we deem it best to give this present species a new name, 

 and it is probable that the Samoan specimens, also represent a new 

 species.
