of caudal peduncle about 2 to 2-J. times in length of head. No orbital 

 tentacles, but there is a pair of slender tapering filaments on the 

 nape ; interorbital space depressed in centre ; snout very obtuse, 

 with anterior profile abruptly descending; upper lip thick and 

 projects beyond lower, maxillary reaches barely to vertical of 

 anterior margin of orbits ; eyes prominent and placed high in the 

 head, bulging at interorbital space. 



Dorsal xi 18 ; commences over posterior border of operculum and 

 does not quite reach base of caudal ; soft-rayed portion higher than 

 spinous, a notch between spinous and soft dorsal. Pectorals 14 ; 

 slightly longer than head and reach to vertical of origin of anal, 

 pointed, middle rays longest. Ventrals i 2 ; about 4 length of head. 

 Anal 20 ; 1st ray short, remainder about the height of spinous 

 dorsal, membranes incised. Caudal nearly as long as head, truncate, 

 rays divided. Lateral line tubes only apparent anteriorly where the 

 lateral line is arched over the pectorals. 



Colour (of preserved specimens), grey, seven or eight transverse 

 dark bands cross body, extending partly on to fins ; dorsal with dull 

 brown dots, also on caudal, where they form cross bands; scattered 

 over the body more or less distinctly are small circular or oval areas 

 devoid of pigment and sometimes bordered by a dark circle. 



Four specimens, 43 mm., 51 mm., 53 mm., 55 mm. in length, 

 respectively, from Mr. Eobinson, Natal.

A strong slightly-curved canine on each side of lower jaw, a- 

 slightly smaller one on each side of upper [in one specimen one side 

 of the lower jaw had 2 canines]. Depth of body 3^ to 4 times in 

 total length excluding caudal, length of head 3f to 4 times. Distance 

 from eye to point of snout about twice interorbital width and 1? to 

 14 times diameter of eye, which is 4-J- to 5 times in length of head ; 

 depth of caudal peduncle 2| to 3 times in length of head. A 

 tapering filament, longer in the males than the females, with a group 

 of shorter filaments springing from its base on each side is situated 

 on upper posterior angle of each eye, and the anterior nostril has a
