208 KECORDS OF THE AUSTRALIAN MUSEUM. 



a specimen in which the markings are very well defined and such 

 consist of a longitudinal black band which passes from the snout, 

 through the eye to the tail : it deepens posteriorly and embraces 

 the body and caudal peduncle and is also continued in blotches 

 on to the dorsal and anal fins. The top of the head and the 

 back including the fin is white. In other examples the band is 

 brown, sometimes very faint, and the vertical fins may be of the 

 same tint ; when the head-band is pale in colour it may have a 

 black lower margin ; the extension of the band posteriorly may 

 be indicated by some spots on the side of the tail. The pectorals 

 are generally and the ventrals always white, and if the vertical 

 fins are coloured they have a light margin. 



Of many specimens examined, the largest measured 57 mm. in 

 length. This species has been taken at various times in rock 

 pools at Long Bay, near Sydney, by Mr. A. R. McCulloch. 



OpHIOCLINUS flABRIELI, sp. nov. 



(Plate xxxvi., fig. 7). 



D. li. + 1 ; A. 36 ; P. 12 ; V. 2 ; C. 1 1+ 4 ; Vert. 21 + 39 = 60. 



Length of head 5-3 ; height of body, at the origin of the anal, 

 7*5 ; length of caudal 8-0 in the total. Eye prominent, large, 

 close to the upper profile, 4-2 in the length of the head, and twice 

 the interorbital space. Length of snout little more than half the 

 diameter of the eye and bearing two short tentacles, immediately 

 above the upper lip. The maxilla i-eaches to beneath the third 

 fourth of the eye. 



Teeth. — An extensive patch of small granular teeth within the 

 margin of each jaw, followed by a narrow band on each side ; 

 teeth on the vomer but none on the palatines. A broad frenum 

 in the upper jaw. 



Fins. — -The dorsal commences above the opercle, but its origin 

 is not well defined, and is composed wholly of spines with the excep- 

 tion of one ray, the last,w]uch is joined to the caudal : the fin rises 

 rapidly to the fourth spint; and thence is of fairly uniform height, 

 the spines lengthening somewhat posteriorly ; the median height 

 of the fin is about one-third that of the body at the commence- 

 ment of the anal. 



The anal fin arises beneath the nineteenth or twentieth dorsal 

 spine and is formed wliolly of soft rays ; it is similar to, but 

 slightly higher than the dorsal and is joined to the caudal. The 

 pectoral is short and rounded, its middle rays 2-4 in the length of 

 the head. The ventrals are jugular in position, close together
