One specimen, 329 mm. in length, from Mr. Robinson, Natal, 

 taken off Durban Breakwater. 



A second and smaller specimen, 149 mm. in length, from the 

 Durban Museum seems to be an immature form of the above. 

 It differs from it in the following respects : Snout 2f times 

 diameter of eye, which is 1^ times in interorbital width and 4 times 

 in length of head. Snout slightly concave ; distance from anterior 

 nostril to front edge of upper jaw f length of head and equals 

 distance from eye to angle of mouth. Dorsal ix 25. Pectorals 

 as long as head, ventrals slightly shorter. Anal iii 24. Free 

 portion of tail at lowest part about 1-^ times diameter of eye. Spine

Teeth, in 2 rows on lower jaw; 2 rows in upper jaw, becoming 

 single in last fifth of upper jaw : teeth on vomer in triangular patch ; 

 on palate in a broad, elongate band ; and on tongue. Depth of body 

 3f times in total length excluding caudal, 4^ times including caudal ; 

 length of head 5 times. Snout If times diameter of eye, which is 

 nearly twice in interorbital width and over 5i times in length of 

 head. Profile behind orbits slightly concave ; cleft of mouth deep 

 and slightly oblique, maxillary reaches to vertical of posterior margin 

 of orbits, lower jaw longer than upper. 



Dorsal vi, i 20 ; spines flattened, laterally expanded into a 

 lanceolate form, each spine does not extend to the base of the one 

 next it. Second dorsal commences about midway between caudal 

 and snout ; its first portion elevated, nearly f length of head, about 

 ^ height of body, and -^o longer than anterior anal rays ; the last 

 9 rays are semi-detached, the last ray a little elongated. Pectorals 

 nearly f length of head. Ventrals nearly ~ length of head. Anal ii, 

 i 18, resembles soft dorsal ; detached spines moderately strong, 

 2nd spine longest and about ^ height of anterior soft rays. Caudal
