Platophrys dimorphus, n.sp. 



(Plate XXVII.) 

 D. 8;. A. 72. V. 6. L. 1. 50. 



Depth of bod}- i* in length without caudal; length of head 

 4| ; longitudinal diameter of eye about 3^ times in head, i^ in 

 interorbital space (in the male, less than i in the female) and 

 less than the distance of the lower from the end of snout. The 

 posterior margin of the lower eye is near the vertical from the 

 anterior margin of the upper. Lower jaw projects beyond 

 upper ; the maxillary scarcely reaches to the anterior border of 

 the lower eye. In the male there is a strong spine in front of 

 the lower eye projecting beyond the profile of the snout and 

 a few tubercles on the (morphologically) upper margin of the 

 orbit of either eye. These are absent in the female. A further 

 sexual distinction is the presence of cutaneous flaps on the 

 posterior margin of the eye in the male only. Teeth : a single 

 row of fine setose teeth on the upper and under jaws. 



Rays in anterior half of dorsal the longest, about li^ in head. 

 The first two or three anterior and posterior rays are to the 

 right of the median line. Left pectoral, excluding prolonged 

 ray, a little less than the length of the head ; with prolonged ray, 

 which is usuall)' thougli not invariably present in the male, it is 

 i4 in the length of head. The right pectoral is smaller than 

 the left about \\ in the length of the latter. The right ventral 

 is in the middle line in advance of the left which is entirely on 

 the side. The posterior extremity of the left reaches beyond 

 that of the right. The left is coloured, the right being un- 

 coloured. 



Scales: Ctenoid on the left side, cycloid on the right, the 

 lateral line has anteriorly a strong cur\'e whose depth is about 

 half its length. 



Colour: Male, dark grey with minute black dots on anterior 

 border of region between the eye and on ocular flaps, female of 

 the same colour with the addition of dark spots or blotches 

 often arranged in rows of 3 or 4 along the middle of the body 

 and on either side above and below it. 



Locality: 2\ miles off L^mhlanga River mouth (Natal);, 

 depth, 22-26 fathoms ; bottom, fine sand.
