-4 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Entire body and head, with the exception of the chin and 

 the tip of the snout, covered with ciHated scales ; on the upper 

 parts of the head they are small and irregular, larger on the 

 cheeks, and very large on the operculum and body. They 

 extend about half-way up the vertical fins between the spines 

 and rays, and there is a scaly sheath at the bases of the 

 spinous dorsal and anterior part of the anal ; small scales also 

 cover the base and sides of the tail and basal portion of the 

 pectoral. A large pointed scale at the base of the ventral. 

 Lateral line curved and terminating below the middle of the 

 soft dorsal ; a second, less distinct, series of tubes runs along 

 the middle of the caudal peduncle, covering eight or nine 

 scales. There are twenty-seven scales between the head and 

 the hypural. 



Origin of the dorsal over or a little behind the opercular 

 spine. The first spine is short, two-thirds as long as the eye, 

 the fifth and sixth the longest and half as long as the head ; 

 thence they decrease slightly, the last being three-fourths the 

 length of the fifth. The soft dorsal is somewhat angular, its 

 sixth ray the longest and one and a half in the head. Anal 

 oblong, the first to the tenth rays subequal, one and a third 

 in the head ; second spine very strong and but little shorter 

 than the rays. Upper rays of the pectoral longest, longer 

 than the head. Ventrals pointed, the first ray produced and 

 reaching beyond the vent. Caudal forked, the upper lobe 

 longer and more pointed than the lower. 



Colour. — Olive-green above, the head and lower surfaces 

 yellowish, each scale of the back and sides with a darker 

 centre. Spinous dorsal dusky, especially towards its margin. 

 Soft dorsal and anal each with an indistinct dark median 

 band. Base of the pectoral with a conspicuous blackish spot 

 covering its upper half. A whitish spot on the upper part of 

 the caudal peduncle immediately behind the dorsal. 



Described from three specimens, one iS8 mm. long, from 

 the coast near vSydney, and two others in the Australian 

 Museum from Lord Howe Island, 123-160 mm. long. 



Chromis? immacui..'\tus, Of^ilhy. 



Helittstes iuiniaculatus, Ogilby, Proc. Linn. Soc. N.S. Wales, 



X., i8<S6, p. 446; id., Waite, Mem. Austr. Mus., iv., 



1899, p. 86, pi. xiv. 



When writing on this species, Waite {loc. cit.) suggested 



that it was identical with C. hyp.silepis, and later, in his 



Catalogue of the Fishes of New South Wales, 1 he quotes hi&
