DENTEX EOBINSONI, n. sp. 



Teeth, 4 rather small canines in upper jaw which hardly differ 

 from the canine-like teeth about 7 in number which follow ; 4 canines 

 on lower jaw separated by an interspace (filled with small teeth) 

 from the succeeding canine-like teeth about 9 in number. Depth of 

 body 2^ times in total length excluding caudal, length of head 3 times. 

 Snout 1J times diameter of eye, which equals interorbital width and 

 is 3 times in length of head. Profile of head descends in an oblique 

 line from nape to snout ; interorbital space flat, a depression on each 

 side of nape above orbits ; depth of preorbital nearly equals diameter 

 of eye ; cleft of mouth oblique, jaws about equal, maxillary reaches 

 to vertical of anterior nostril and is almost entirely hidden by 

 preorbital ; 5 series of scales on preoperculurn which is entire ; 

 preopercular border and preorbital without scales and covered with 

 minute pores ; operculum scaly, with an inconspicuous spine. 



Dorsal x 11 ; spines slender and rather flexible, 3rd spine longest 

 slightly more than ^ length of head, succeeding spines decreasing in 

 length to the last which is a little longer than penultimate one and 

 about the same height as the 3rd but shorter than the soft rays. 

 Pectorals f length of head. Ventrals f length of head, reaching to 

 origin of anal. Anal iii 9 ; spines moderately strong, 3rd longest ; 

 soft rays a little lower than those of soft dorsal. Caudal damaged 

 in specimen ; lat. 1. 45, lat. tr. /y. 



Colour, a pale flesh tint. 



One specimen, 260 mm. in length, from Mr. Eomer Eobinson 

 Natal ; who supplies a note of the colour, and states that the fish 

 is taken on hand-lines in the open sea off the Natal Coast south of 

 Durban. 



APRION FILAMENTOSUS (C. and V.). 



Teeth, villiform with an outer row of widely set canines, the anterior 

 ones largest. Depth of body nearly 3^ times in total length exclud- 

 ing caudal, length of head nearly 4 times. Snout equals interorbital 

 width and is If times diameter of eye, which is 4i times in length 

 of head ; distance between eye and angle of mouth equals T V diameter 

 of orbit. Lower jaw prominent projecting beyond upper, maxillary 

 reaches to vertical of anterior third of eye and slightly covered by 

 preorbital ; preoperculurn emarginate, angle rounded and slightly 

 produced ; 7 series of scales between eye and angle of preoperculurn ; 

 operculum with two blunt inconspicuous spines. 



Dorsal x 11; spines strong; 4th spine longest nearly -J length of
