third dorsal spine. The first ray is 31 in the head, and rather more than 
twice as long as the last ray. 
Origin of the pectoral near to the opercular margin; its length about 
3 times that of the first dorsal ray, and reaching backward as far as the 
vertical from the eighth dorsal spine. 
Ventral inserted a little behind the base of the pectoral, its spine sub-

observed huge shoals moving in a wide circle round some rocky island, or

Chromis dispilus n. sp. (Plate 25.) 
The following key will serve to show the principal distinguishing characters 
between Chromis dispilus and its Australian congener : 
A. One white spot placed above the caudal peduncle immediately 
behind the dorsal fin. Snout obtuse, the profile markedly 
convex above the sye. Median dorsal spines shorter than 
is pi ies % ‚.- hypsilepis. 
AA. Two white spots, one below the tenth-eleventh dorsal spines, 
and the other below the posterior dorsal rays. Snout 
pointed, the profile not markedly convex above the eye. 
Median dorsal spines as long as the longest dorsal rays .. dispilus n. sp.
