FAMILY PERCIIXE.* 



AULACOCEPHALUS TEMMINCKII, Bleek. 



(Yellow-stripe Eock Cod.) 



DEPTH of body 3 times in total length excluding caudal, length of 

 head 2^ to 2f times ; snout 2.^ times diameter of eye, which is 

 6J- times in length of head, and equal to or slightly less than 

 interorbital space ; lower jaw projecting ; maxillary extending to 

 below centre of eye, the width of its distal extremity about diameter 

 of eye. Gill-rakers longer than gill-fringes, 17 or 18 on lower part 

 of anterior arch. 



Dorsal ix 12; originating above base of pectoral; third or fourth 

 spines longest, about 3f in head, shorter than longest soft ray ; a 

 deep notch between spinous and soft portions of tin. Pectorals 

 2 1 in head ; ventrals shorter. Anal iii 9 ; second and third spines 

 about equal, hardly half as long as longest soft ray. Caudal truncate. 

 Lateral line strongly curved, approaching the spinous dorsal, forming 

 an angle below the last dorsal ray. 



Colour, a broad yellow stripe runs along near the dorsal region of 

 the body, from the upper base of the caudal through the eye to the 

 end of the snout. 



Two specimens, one 230 mm. in length presented by Mr. Quekett, 

 of the Durban Museum, the other 250 mm. in length from Mr. 

 Robinson, Natal. They agree with the description of A. temminckii, 

 but the rays of the soft dorsal are relatively a little longer, and there 

 is no bifurcation of the yellow stripe. 



A. temminckii occurs in the Sea of Japan, Siam, and Mauritius. 



GRAMMISTES SEXLINEATUS, Thuub. 



Teeth, in villiform bands on jaws, a small chevron- shaped band on 

 vomer, a band on palatines. Depth of body 2 to 2i times in total 



* The older classification of families is retained for present purposes.
