below, rest of fin paler or gray-brown. Pectoral and ventral pale 

 brown. 



Length 70 mm. 



Type, No. 47,541, A. N. S. P. 



Philippine Islands. Presented by the Commercial Museums of 

 Philadelphia. 



Also Nos. 47,542 to 47,547, paratypes, same data. These show: 

 Head 3 to Sf; depth If to 2; D. XII, 11, once XII, 10; A. II, 11, 

 rarely II, 10 to II, 12; tubes in upper arch of 1.1. 15, rarely 14; pores 

 in straight portion of 1.1. 10, rarely 9 or 12; snout 3| to 4 in head 

 measured from upper jaw tip; eye 2f to 2|; maxillary 2f to 3|; 

 interorbital 2f to 2|; length 58 to 75 mm. Some of the smaller ones 

 show a slight depression concavely above eye in upper profile. 



Allied with Chromis ternatensis (Bleeker), especially in its pale 

 anal and dark edged caudal, though differs in its preorbital not 

 half so wide as in Bleeker's figure. ^^ Day's figure of Heliastes lepi- 

 durus^'^ is close in proportions, and is likely identical with the present 

 species. His figure differs in a radiation of scales below the eye 

 and the dark pectoral spot appears above the pectoral base and not 

 on the base of first ray. 



HOPLOCHROMIS subgan. nov. 

 Type Helioses cceruleus Cuvier. 



Differs from the subgenus Chromis, as represented by the preceding 

 species, in the presence of external outwardly directed conic teeth 

 in each jaw. 



("O-Xdv, armour; Chromis; with reference to the external series of 

 teeth.) 

 Chromis caeruleus (Cuvier). 



Six examples.

 to spinous anal origin; 6 predorsal scales; head width 2 in its length; 

 head depth 1^; snout 2\; eye 6f ; maxillary 5; interorbital 2f ; third
