Dorsal xi 11 ; spines strong, received in a groove, each alternate 

 one strongest and flattened (4 mm.) on one side ; 4th spine longest, 

 slightly less than ^ length of head ; spinous portion of fin higher 

 than the soft. Pectorals a little longer than head, 5th and 6th rays 

 longest, reach to origin of anal. Ventrals f to length of head ; 

 spine fairly strong, compressed and nearly - length of 1st soft ray. 

 Anal iii 8 ; 2nd spine strong, longer than 3rd and about same 

 length as longest dorsal spine. Caudal emarginate. Scales ciliated, 

 but very feebly above lateral line ; lat. 1. 44-46, lat. tr. ^ r . 



Colour (of preserved specimen), whitish, dorsal edged with black, 

 a black patch at commencement of lateral line. 



Three specimens, 160 mm., 2L8 mm., 226 mm. in length respec- 

 tively, from Mr Eobinson, Natal. 



CHEYSOPHRYS NATALENSIS, Cast. 

 (Silver Bream.) 



Teeth, 6 canines on each jaw ; molars in 4 rows on upper, 3 rows 

 on lower jaw, the last teeth of inner series being the largest. Depth 

 of body 2i times in total length excluding caudal, length of head 

 3| times. Snout about 2J times diameter of eye, which is If times 

 in interorbital width and 4^ times in length of head. Dorsal profile 

 is an uninterrupted and gentle curve from end of snout to beginning 

 of dorsal fin ; a protuberance above anterior upper angle of orbits ; 

 upper jaw projects slightly beyond lower ; maxillary reaches to 

 vertical of anterior margin of orbits ; preorbital slightly emarginate, 

 height 1^- times diameter of eye, 6 series of scales between preorbital 

 and angle of preoperculum ; spine on opercle small and inconspicuous. 



Dorsal xi 13 ; spines flexible, received into a sheath ; 4th spine 

 longest, nearly ^ length of head and longer than longest soft rays. 

 Pectorals lf ! () times length of head, 5th and 6th rays longest, reach 

 to vertical of commencement of soft anal. Ventrals about f length 

 of head, scarcely reach to vent. Anal iii 11 ; spines moderately 

 strong, 2nd and 3rd about equal, about same length as longest rays 

 and f length of longest dorsal spine. Caudal forked, lobes covered 

 with small scales. Scales cycloid above lateral line and feebly 

 ciliated below. Lat. 1. 62, lat. tr. f|-. 



Colour (of preserved specimen), pale brown, margin of dorsal dark, 

 a black band between and over eyes. 



One specimen, 280 mm. in length, from Mr. Eobinson, Natal. 



It is probably the C. natalensis of Castelnau, but his description 

 is insufficient.
