CHROMIS SCOTOCHILOPTERUS Fowler 



Ghromis scotochilopterus Fowler, Proc. Acad. Nat. Sci. Phila., 1918, p. 61, 

 fig. 24. Philippine Islands. 



Depth 1% to 21/4 ; head 3 to 3i/4, width 1% to 1%. Snout 4 to 41/3 

 in head ; eye 2% to 3^, greater than snout, 1% in interorbital or little 

 greater than interorbital in young; maxillary reaches little beyond 

 front eye edge or to front pupil edge, 2% to 2% in head ; teeth conic, 

 outer series little enlarged in each jaw and inner biserial row of 

 smaller ones above and uniserial inner row of smaller lower ones; 

 interorbital 2% to 3%, broadly convex; hind preopercle edge entire. 

 Gill rakers 10+13, lanceolate, long. 



Tubes in lateral line 17 to 19, pores in straight section 7 to ll-j-l or 

 2; 3 scales above lateral line to spinous dorsal origin, 9 below, pre- 

 dorsal 32; 6 rows of cheek scales, two median rows enlarged. Scales 

 with 6 to 9 basal radiating striae; apical denticles 130 to 134, with 

 3 to 8 transverse series of basal elements. 



D. XIII, 10, 1 or 11, 1, thirteenth spine 2 to 2l^ in head, fourth ray 

 1% to iy2, first ray often simple; A. II, 11, i, second spine 1%, first 

 ray 1^/4 to II/3, often simple; least depth of caudal peduncle 2 to ^Ys', 

 caudal sharply forked, 21/^ to 2% in combined head and body; pec- 

 toral 3 to 31/1 ; ventral 3 to 31/3. 



Back deep umber to dusky, more brownish on sides and pale brown 

 below. Iris neutral brown. Preorbital grayish. Cheeks and breast 

 with drab tinge. Pectoral, most of soft dorsal, greater median 

 portion of caudal and most of anal dull yellowish white. On 

 all last fins contrast with blackish, as both upper and lower edges of 

 caudal broadly blackish, former extending along caudal peduncle 

 above and lower or front anal edge. Small dusky brown spot at pec- 

 toral origin, not sharply defined and sometimes inconspicuous, axil 

 pale. Paired fins pale brownish or grayish. 



Only known from the Philippines. It bears some superficial re- 

 semblance to ChroTiiis notatus Schlegel, of which we have compared 

 11 examples, 8244 U.S.N.M. from the Riu Kiu Islands, obtained by 

 William Stimpson, which measure 112 to 130 mm. Ghroonis noiatu^ 

 differs, however, strikingly in the black blotch at the pectoral base 

 and a white blotch at the bases of the last dorsal raj'^s.
