finely scaled basally. Ventral with pointed axillary scale half 
length of fin spine. Lateral line with long exposed simple tubes in 
upper section. First dorsal lower than second, with 12 spines and 
edge of each membrane notched, rays 11. Anal with 2 spines and 11 
rays. Caudal emarginate. Pectoral shorter than ventral. 
Though the genotype was originally included in Dascyllus it has 
little in common with the Dascyllinae. It seems to me more closely 
related to the various genera of the Chrominae, and is especially dis- 
tinguished by its serrated preopercle, strong dentition and combina- 
tion with other characters.

LEPICEPHALOCHROMIS, new genus 
Type.—Chromis cupreus Fowler and Bean. 
Teeth with main row of large simple conic ones in each jaw; in- 
side a band of irregular small ones, one to three transverse series 
for almost whole of upper jaw and in lower jaw.similar band only 
anteriorly. Head with many small scales around eye on chin, along 
edge of preopercle flange, lower inner edges of head forming gill 
opening and at bases of all of scales on top of head. Each tube of 
lateral line well exposed, with several very short anal tubes or 
branches both above and below. Gill rakers 9+25, lanceolate, little 
shorter than gill filaments, which are 34 of eye. Preorbital edge not 
free. Preopercle edge well free, distinct and entire. Pectoral axil 
dark brown. 
Apparently related to Chromis in its largely uniform coloration, 
without the blue spots of Heliases, though agreeing with the latter 
in the possession of 13 dorsal spines. It also appears to be distin- 
guished by the small scales on the cheek in 8 rows, besides the very 
small and crowded scales elsewhere on the head.
