 total length, length of head 5 times. Diameter of eyes 9 times 

 in length of head, equal to inter-ocular width ; length of 

 mouth three times in length of head. Dorsal with 73

This species is easily distinguished from its two South 

 African congeners, and necessitates the following addition to 

 the synopsis given in the first part of these reports (1898 p. i). 



1 1. Snout projecting beyond the lower jaw, hooked ; upper 

 eye in advance of the lower. 



B. Caudal fin confluent with dorsal and anal.

Right pectoral fin longer than head. Synaptura pectoraltSy 

 Kaup. 



Right pectoral fin |^ to f length of head. Synaptura micro- 

 lepis, Blkr.

 Blgr. 



HIPPOCAMPUS CAPENSIS. 



10 segments on the body, 34 on the tail, tubercles absent on 

 the head and body, short and blunt on the tail. Snout very 

 short, hardly twice diameter of eye, shorter than postorbital
