FAMILY GOBIID^E. 



GOBIUS GIUEIS, B. H. 



Teeth of outer series enlarged ; no canines. Depth of body 5J 

 to 5| times in total length excluding caudal, length of head 3^ to 3^ 

 times. Snout 2 to 2 times diameter of eye, which is 8^ to 7i times 

 in length of head and 1^ times in interorbital width ; greatest width 

 of head f to 4 its length, greatest depth about ?-. Interorbital space 

 flat or very slightly concave ; lower jaw projects beyond upper, 

 maxillary reaches to vertical of anterior margin of eye. 



Dorsal vi, i 9; spines flexible; 3rd spine of 1st dorsal longest, 

 about length of head, succeeding spines shortening. The 2nd 

 dorsal has the soft rays about same height as longest spine of 1st 

 dorsal, and the posterior rays reach nearly to base of caudal. Pec- 

 torals f length of head and same length as ventrals. Anal i 8 ; 

 similar to soft dorsal and about the same height. Caudal pointed, 

 f length of head. Scales, vert. 11-12 ; extend over head almost to 

 eyes where they are very much smaller than those on the rest of the 

 body ; 20 rows before base of 1st dorsal fin. Scales on body com- 

 paratively large, angular and ctenoid. 



Colour (of preserved specimens), yellowish brown, with dark 

 markings on head and irregular dark blotches on body, vertical fins 

 spotted. 



Two specimens, 263 mm. and 218 mm. in length, respectively, 

 from Mr. Eomer Eobinson, Natal ; from Umgeni Lagoon, Durban. 



These specimens do not agree exactly with Day's G. giuris, 

 differing in the number of scales before the dorsal ; nor with G. 

 giuris of Kner (Novara), which is provided with " einem deutlich 

 vortretenden stumpfen dome" on the preoperculum, not observed in 

 either of our specimens. 



ELEOTRIS FUSCA, Schn. 



Teeth, in villiform rows, those of outer row in upper jaw larger 

 and further apart ; 4 or 5 large teeth anteriorly in lower jaw, and 

 laterally some pointed teeth in outer row larger than remainder. 

 Depth of body 4f times in total length excluding caudal, length of 

 head 3^ times. Snout 1J times diameter of eye, which is 6^ times 

 in length of head and 2^- times in interorbital width. Head de- 

 pressed, greatest width about equal to its depth and f its length ; 

 lower jaw slightly longer than upper, maxillary reaches to vertical 

 of anterior third of orbits ; anterior nostril with a pointed flap ; angle
