lateral line ; 3 dark lines, one on upper border, one across the 

 middle, and one on the lower border of the eye. 



Two specimens, 245 mm. and 260 mm. in length respectively, 

 from Mr. Eobinson, Natal ; the fish is caught by deep-sea boats on 

 the Natal coast. 



The specimens agree closely with Gimther's D. praorbitalis, 

 allowing for difference in size of fish. 



GEBRES LONGIROSTRIS, Giinth. 



Depth of body 2 to 2J times in total length excluding caudal, 

 length of head 3 to 3-1 times. Snout equals diameter of eye, which 

 is 1 to 1 times in interorbital width and 3 to 3-^ times in length of 

 head. Snout produced slightly, flattened between nostrils ; cleft of 

 mouth lateral, upper lip very protractile, maxillary reaches to vertical 

 of anterior third of orbits ; preopercle entire. 



Dorsal ix 10 ; spines flexible, 2nd longest, about 4 length of head 

 and slightly arched ; spinous portion higher than the soft, last dorsal 

 spine shorter than first soft rays. Pectorals If to about 11 length 

 of head, reach to anal. Ventrals about f length of head. Anal iii 

 7 ; spines moderately strong, 3rd longest or about same length as 2nd 

 and i length of longest dorsal spine ; anterior rays slightly shorter, 

 the last two-thirds of the fin being subequal and about ^ the length. 

 Caudal forked, covered with scales. Scales cycloid, comparatively 

 large ; lat. 1. 46, lat. tr. /V. 



Colour of fresh specimen silvery, with about 9 dark longitudinal 

 stripes, ventral and anal bright yellow. 



This fish does not differ much from G. loiiyirostris, Giinth., 

 recorded from the Cape of Good Hope. 



Three specimens, 165 mm., 163 mm., and 128 mm. in length 

 respectively, the first from Mr. Eobinson, Natal, the other two 

 from fishermen at Durban Harbour. 



Two species of Gerres from Natal apparently differ from these 

 specimens in length of body, &c., but are too imperfect for 

 identification. 



DlNOPERCA QUEKETTI, Blgr. 



(Black-fish.) 



Depth of body 2-| times in total length excluding caudal, length of 

 head 3 times. Snout equal .to interorbital width and slightly less 

 than diameter of eye, which is 3 to 3J times in length of head. 

 Preoperculum serrated, seme coarser at the angle, which is rounded 

 and very slightly produced ; 2 minute spines on operculum ;
