CHBOMIS RETICULATUS, new species 



Depth 2 to 2y8 ; head 31/2 to Z%, width I2/3 to 1%. Snout 33^ to 

 S% in head from snout tip; eye 3i^ to Sy^, greater than snout, ll^ 

 to 114 in interorbital ; maxillary reaches opposite front eye edge or 

 slightly beyond, 2% to 3 in head from snout tip ; teeth conic, in nar- 

 row bands in jaws, with outer enlarged series and inner narrow 

 band of 1 to 3 irregular series; interorbital 2% to 2%, broadly 

 convex; preorbital not free; preopercle edge entire. Gill rakers 

 8+21, lanceolate, slender, ly^ in gill filaments, which 1% in eye. 



Scales 17 or 18 tubular in upper section of lateral line, pores in 

 lower or straight section 8 or 9 to caudal base, often first few may be 

 irregular or variously separated by 1 to 3 scales. Preorbital with 

 single row of scales and 4 rows on cheek. Vertical fins all more 

 or less finely scaled basally. Scales with 8 basal radiating striae, 

 edge scalloped; apical denticles 160 to 171, with 12 transverse series 

 of basal elements ; circuli very fine. 



D. XIII, 10, I or 11, I, fourth dorsal spine 2 in total head length, 

 third spine 1 to ly^ ; A. II, 11, i or 12, i, second spine U/q to 2, fourth 

 ray I14 to 1%; least depth of caudal peduncle 1% to lyg; caudal 

 deeply forked, slender lobes narrowly and sharply pointed, 21/^ to 

 21/^ in combined head and body; pectoral 2% to 3-^1 ventral 3 to 3%. 



Brown generally, but slightly paler on breast and abdomen. Each 

 scale of body with a slightly darker narrow edge, less distinct or 

 only on upper surface of head. Iris brownish, with narrow pale 

 circle around pupil. Paired fins pale, uniform, or with yellowish 

 tint. Dorsals largely dusky, only posterior margin of soft dorsal 

 pale or whitish and rather narrowly so and in contrast, Anals simi- 

 lar. Caudal pale medially, upper and lower edges rather broadly 

 dusky brown and though distinctly so not in sharp contrast with 

 rest of fin. 



Known only from the type and paratypes listed below. They 

 are closely related to Chromis scotochilopterus, largely with similar 

 general color pattern. The presence of the dark reticulated edges 

 of the scales is different from that in any species of the genus. The 

 dark areas on the soft dorsal and anal are far more extensive than 

 in any specimens of Chromis scotochUopterus and the dark bands 

 on the tail far less contrasted.

10765 and 1070G. Sipadan Island. September 28, 1909. Length, 140 to 150 

 mm. [2011.1 3 examples. Scales with very dark olive edge, central body 

 blue, merging into olive on hind edges ; head more dusky, snout whitish. 

 Dorsal similar to body, becoming blackish distally, vertical edge hyaline 

 and rays, pale at tips. Caudal lobes broadly black on edges, middle of fin 

 dusky-yellowish, rays and membranes hyaline at tips within fork, except
