pelvic rays grayish, membranes clear, pectoral similarly colored, base 

 of pectoral dark reddish brown, minute black spot on base of upper 

 ray. 



Remarks. — A careful examination of the type of Dascyllus poinacen- 

 troides reveals 2 or 3 scales, with small basal scales. Alost of the 

 scales are missing from the nape, back and anterior sides. The type 

 has the same number of fin rays as specimens of Chromis lepidolepis 

 from the Philippines and as two specimens from Bikini; also, it has 

 similar jaw teeth, serrated preopercle, body and fin shape, and color- 

 ation (although faded). 



Fowler has made Dascyllus pomacentroides the type of a new genus 

 Serrichromis , "distinguished by its serrated preopercle, strong den- 

 tition in combination with other characters." These characters, 

 held in common with C. lepidolepis, certainly serve to separate this 

 species from others of the genus Chromis, but Fowler has already 

 proposed the subgeneric name Lepidochromis Fowler and Bean 

 (U. S. Nat. Mus. Bull. 100, vol. 7, p. 58, 1928), for this species. 



We propose, in spite of the differences noted above, to leave this 

 species as a subgenus of Chromis, at least for the present, because its 

 jaw teeth, though heavier, are definitely of the same kind as the genus 

 Chromis, as are its oblique mouth, v/ith its long upper jaw, and its 

 general body shape.
