NEW SPECIES OF PHILIPPINE FISHES. 527 



Callyodon ogos Seale, sp. nov. 



Head 3.20; depth 3.70; dorsal IX, 10; anal III, 9; scales 22, 8^ in 

 vertical series; ej'e 5.50 in head; snout 2.85; interorbital 3.15; two rows 

 of scales on cheeks; the lower limb of preojoercle naked; lips wide; a 

 canine tooth at angle of each jaw. 



Body oblong compressed, the upper and lower outlines evenly curved; 

 head rather more pointed than is usual in this genus. Depth of' caudal - 

 peduncle sonaewhat greater than its length, being 2 in head. 



Greatest depth of head 1.14 in its length. Interorbital space convex. 

 The lips are wide, the upper almost wholly covering the teeth, the 

 lower covering more than two-thirds of lower teeth. The teeth in life 

 were rosy. The canine teeth of the lower jaw are largest, those of the 

 upper jaw being rather blimt. Gill rakers iine almost hair-like, short, 

 about 26 on lower limb. Gill openings of moderate width, ending on 

 a line with jDOsterior margin of eye. Pseudobranchia large. 



Scales are large and smooth, body and head are fully scaled except 

 interorbital space, snout, lower limb of preopercle and chin, which are 

 naked. Lips thin, without folds. 



Origin of dorsal midway between tip of snout and base of first dorsal 

 ray, longest spine -2.25 in head, about equal to longest ray. Base of anal 

 1.20 in head, the origin of the fin is considerably nearer the end of 

 caudal vertebra than to angle of preopercle, its posterior ray 2.50 in head. 

 Origin of ventrals considerably posterior to origin of pectorals, being 

 midway between anal and angle of mouth, their length 1.50 in head. 

 Pectorals 1.25 in head, their tip on a line with 8th scale of lateral line. 

 Caudal is slightly lunate. 



Color in life chiefly blue-green ; however, there is a large area occupying 

 the upper and median portion of the sides which is reddish yellow, the 

 margins of the scales in this area are green. The upper anterior portion 

 of back is deep green, the lower portion of sides, belly, and caudal 

 peduncle is deep blue-green. About twelve sliort red lines radiate from 

 eye. A large wedge-shaped deep green area with ]-ed margins extends 

 from posterior margin of eye to posterior margin of opercles, ending 

 just in front of axil of pectorals. Snout deep green. A red line from 

 eye to angle of jaws. Lower lip rosy with blue margin and crossed by 

 blue line at base. Two short longitudinal blue lines on sides of throat, 

 base of pectorals rosy with a deep green line across base of rays. Dorsal 

 rosy at base and broadly margined with deep blue, the median portion 

 of the fin between these colors being bright red above and deep gieen 

 below, the green color fading out and changing into a bright yellow on 

 posterior portion of soft dorsal. Caudal with upper and lower rays bright 

 blue, the second and third upper and lower rays bright pink, the re- 

 mainder of fin rather dark blue. Anal blue-green, the margin and base 

 darker blue, the median portion with tint of pinkish, showing some 

 darker greenish blotches between the rays. Ventrals with rays deep blue-
