\'((riah'oii.. — The occipital lidge is not always developed, and is 

 generally absent in smaller specimens. The anterior anal rays are pro- 

 duced in most larger spe(nmens, but tliey may be shorter than the suc- 

 ceeding ones, as in the holotype of (b'. calvus. Specimens preserved in 

 formaline do not show the white stellate markings which form such a 

 striking feature in the alcohol examples, their markings consisting princi- 

 pally of darker spots arranged in the manner illustrated.

D. xiii/19-20; A. ii/21-22; P. 14; V.3; C.13. Depth at the vent 

 4.8 in the length to the hypural joint; head 4.1-4.2 in the same. Eye 

 4.1-4.4 in the head. Second dorsal spine 1.7-1.8, median dosal rays 

 1.3-1.4, longest anal ray 1.7-1.8 in the head. 



Head much longer than high, the forehead subvertical. Eye 

 separated by a very narrow interorbital space. Occipital crest present 

 in one sex, wanting in the other. A small branched tentacle at the an- 

 terior nostril, a larger simple one above the eye, and a simple one on each 

 side of the neck. No mandibular canines. Margin of the u[)per lip 

 entire ; maxilla reaching behind the vertical of the eye. 



Dorsal fin deeply notched, commencing above the operculum ; the 

 spinous portion is much shorter than the soft. Median dorsal rays longest, 

 the last united with the base of the caudal fin. Anal commencing be- 

 neath the posterior dorsal spines and increasing in height backwards, the 

 last ray not united to the caudal peduncle by membrane. Pectoral 

 rounded, the fifth or sixth lowest ray longest, and reaching to below the 

 tenth or eleventh dorsal spine. Median ventral ray longest, reaching less 

 than half its distance from the vent; the inner ray is slender, and closely 

 ad pressed to the second. Caudal slightly rounded. 



Culoar iiiarl-uiy — Male : — Dark grey in alcohol, with about six 

 paired darker cross-bands, which are piost distinct towards the middle of 

 the body ; intermediate izregular markings are also present. A dark 

 stripe extends from the eye across the mouth on each side, and a blackish 

 spot is present behind the eye. First dorsal with about five broad, dark 

 bands disposed nn)re or less horizontally, the basal ones broader thati 

 those towards the margin. Second dorsal with oblique dusky bands, 

 separated by narrow light, bands; these form darker spots on the rays, 

 and combine to form a dusky margin to the fin. Anal dusky, with narrow, 

 longitudinal, light sti'ipes. Caudal and pectoral almost plain, the lattei' 

 with some indefinite cross-bars. Female: — Light grey in alcohol, with
