EELS OF THE GENUS CONGER — KANAZAWA 243 



Fowler (1912, p. 9) described as new the species Leptocephalus 

 caudalus, from the coast of California. I doubt the validity of this 

 record and discuss this problem on page 228. 



Dr. E. A. Lachner has examined Riippell's type of Conger cinereus 

 (No. 766, total length about 338 mm.) deposited in the Senckenberg 

 Museum at Frankfort, Germany. He noted that the sixth infra- 

 orbital pore is above rictus of jaw, that the lateral line pores from 

 anus forward are 39 in number, and that there may have been a dark 

 streak under the eye.

Specimens studied: Eight specimens, ranging in total length from 

 622 to 950 mm., from the following localities: Brazil, holotype (PM 

 8427) of Kaup's C. hrasiliensis (examined by Dr. E. A. Lachner at 

 Museum National d'Histou-e Natm-elle, Paris) ; Cuba (USNM 24936, 

 9792, 19799); Bahamas, Tm-ks Island (AMNH 7240); Bermuda 

 (CNHM 48606, 48339, 48945). 



Diagnosis: Three supratemporal pores; 11 preoperculo-mandib- 

 ular pores; four supraorbital pores; greater number of compressed 

 teeth in jaws than in other species (fig. 2) ; in young specimens vomer- 

 ine teeth in a single irregular row; premaxillary tooth-patch squarish; 

 ossification developed across sensory canal of preorbital bone, one 

 or two post orbital pores. 



Description: Length of head 126 to 132; tip of snout to origin of 

 dorsal fin 164 to 177; tip of snout to anus 301 to 366; snout length 

 24 to 35; diameter of eye 17 to 19; length of upper jaw (to rictus) 

 44 to 51 ; length of pectoral fins 36 to 42; pectoral fin rays 14 to 17; 

 pores in lateral line 39 to 41; teeth in jaws in a single row, at times 

 with a few scattered teeth on inner row; number of compressed teeth 

 in upper jaw 72 to 90; in lower jaw 74 to 97; vomerine teeth in single 

 irregular row, in large specimens in a traingular patch; premaxillary 

 tooth-patch squarish, with 40 to 105 teeth; preoperculo-mandib- 

 ular pores 11; supratemporal pores 3; supraorbital pores 4, infra- 

 orbital pores 7 or 8; vertebrae 157 to 160; origin of dorsal fin 4.3 

 percent anterior to pectoral tip to 28.35 percent posterior to pectoral 

 tip; ossification developed across sensory canal of preorbital bone 

 (see pi. 1,d); pectoral fins colored black with lower one-third of fin 

 pale. Measurements and counts are recorded in tables 1 to 3, 5, 6 

 and in figure 2.
