EELS OF THE GENUS CONGER KANAZAWA 251 



The affinity of this species is with C. oligoporus from Hawaiian 

 waters, but can be distinguished from it by the following characters: 

 The eye smaller, and more vertebrae and more pores in lateral line 

 (see tables 2, 3, 5). 



I am unable to distinguish the two specimens from Port Alfred, 

 South Africa, from C. jordani, but they are doubtfully included with 

 this species because its geographical distribution is broken consider- 

 abl}^ from that of C. jordani. The origins of dorsal fin of the two 

 African specimens are more anterior in position than in C. jordani. 

 The counts and proportional measurements of the two specimens are 

 given below (one specimen had a mutilated head so some of the 

 characters are not given) : total length 409 and approximately 635 

 mm.; pores in lateral line 40; pectoral rays 17 and 16; vertebrae 144 

 (X-ray); compressed teeth in upper jaw 42 and 55, in lower jaw 40 

 and 56; one row of teeth in jaws; a few scattered teeth in inner row; 

 preoperculo-mandibular pores 9 ; supratemporal pore 1 ; dorsal rays 

 282; anal rays 228; origin of dorsal fin 24.25 percent behind posterior 

 tip of pectoral fin ; preorbital bone bridged over sensory canal ; length 

 of head 134 and 144; tip of snout to origin of dorsal fin 176; tip of 

 snout to anus 374 and 386; snout length 32 and 40; diameter of eye 16 

 and 21; interorbital 21; length of upper jaw to rictus 45; length of 

 pectoral fin 40; premaxillary tooth-patch wider than long. 



Some preserved specimens of C. myriaster that lose their white 

 markings around the sensory pores are difficult to distinguish from 

 C. jordani. To separate these specimens see remarks for C. myriaster. 



The new species is named for David Starr Jordan, who pioneered 

 in studies of Japanese fishes.
