Olyphisodon javanicus (Van Hasselt) Bleeker, Nat. Verb. Holl. Maatsch. 

 Harlem, (No. 6), ser. 3, vol. 2, 1877, p. 156 (name in synonymy). 



Depth 21/s to 2% ; head 3% to 3i^, width 1% to 2. Snout Z% to 

 4l^; eye 2% to 3, greater than snout, 1% in snout, greater than 

 interorbital in young; maxillary reaches opposite front pupil 

 edge, 2% to 2% in head ; teeth conic, outer slightly enlarged row and 

 inner irregular biserial row of small ones; interorbital 2% to 3 in 

 head, broadly convex; hind preopercle edge entire. Gill rakers 

 8+22, lanceolate, slender, rather long. 



Tubes in lateral line 18 or 19, pores in straight section 7 or 8+1 to 

 3; 3 scales above lateral line to spinous dorsal origin, 9 below, 34 

 predorsal forward to snout end ; 5 rows of cheek scales ; infraorbital 

 not free. Scales with 8 to 10 basal radiating striae, sometimes with 



1 to 3 auxiliaries; apical denticles 86 to 122, basal elements in 4 

 transverse series; circuli very fine. 



D. XIII, rarely XIV, 11, i, fifth ray 1% to 1% in head, first ray 

 usually simple; A. II, 11, i, second spine ly^ to 1%, first ray 1% to 

 ly^; caudal sharply forked, li^ to 1% in combined head and body; 

 pectoral 3 to 3^4 ; ventral 2% to 3i/4 ; least depth of caudal peduncle 



2 to 21/8 in head. 



Deep umber to chocolate brown, below paler, sometimes with 

 whitish about breast and belly, though most examples with lower 

 regions more or less swarthy. Iris brown. Many young examples 

 paler or more light brown and with silvery reflections on lower sides 

 of head, breast, and abdomen. Fins brown. Upper and lower 

 caudal edges slightly deeper brown in young, not evident in larger 

 examples. Paired fins paler and obscure small brown spot at pec- 

 toral axil, not evident in most adults. 



East Indian region. 



Occasionally we find an example with 14 dorsal spines. These 

 represent Chromis insuUndicus Bleeker, which differs in no other 

 way from Chromis dnerascens. Bleeker had but a single example, 

 the t5^pe of his Chromis insuUndicus. The variation of our series 

 of Chromis cinemscens exceed the variant he attempted to establish 

 as Chromis insuUndicus.
