Holotype: USNM 71844, 606 mm. in total length, collected in 

 1906 at Misaki, Japan, by the Albatross. 



Paratypes: Japan: USNM 26250; Misaki USNM 49866, 71843, 

 71715, 71716, 71845, 72003, 71963, UMMZ 14280, 165503-4, SNHM 

 12924-5, 2.3466; Kagoshima USNM 163467; Tokyo market USNM 

 71818, UMMZ 165537, 165521; Suruga Bay, Shimizu Market UMMZ 

 165508; Nagasaki UMMZ 165517 (3), 165535; Okinawa: USNM 

 71819. 



Diagnosis: One row of teeth in jaws; origin of dorsal from 11 to 

 80 percent of pectoral fin behind posterior tip of pectoral fin; verte- 

 brae 141 to 144; pores in lateral line 36 to 40; diameter of eye 18 to 26. 



Description: In the following description the fu'st figure is for the 

 holotype; the figures in parentheses refer to paratypes. Length of 

 head 144 (125 to 148); tip of snout to origin of dorsal fin 200 (180 to 

 217) ; tip of snout to anus 379 (352 to 388) ; snout length 35 (30 to 37) ; 

 diameter of eye 21 (18 to 26); length of pectoral fin 49 (40 to 56); 

 upper jaw (to rictus) 49 (36 to 51) ; pores in lateral line 37 to 38 (36 to 

 40) ; supratemporal pore 1 ; preoperculo-mandibular pores 9 ; vertebrae 

 141 to 143 (48 to 50 precaudal, + 92 to 94 caudal); in two specimens 

 dorsal raj^s 301 and 307 and anal rays 225 and 240; pectoral rays 17 

 (15 to 18) ; compressed teeth in upper jaw 42 to 77; 1 row of teeth in 

 upper jaw, occasionally a few teeth in inner row anteriorly; pre- 

 maxillary tooth-patch wider than long. In large specimens the 

 ossification of preorbital bone bridges over sensory canal; in small 

 specimens ossification not bridged over (PI. 1,g). Origin of dorsal fin 

 28.58 percent of pectoral fin behind posterior tip of pectoral fin (14.65 

 to 76.95 percent behind pectoral tip). Color notes taken by Dr. C. L. 

 Hubbs for specimen UMMZ 165504 is as follows: Purplish brown fins, 

 blue gray at base and inky black in margin. 



Geographical range: From Tokyo Bay southward to Nagasaki, 

 Okinawa, and Africa. 



Remarks: The paratypes of Leptocephalus erebennus Jordan and 

 Snyder (USNM 49866, SNHM 12924 and 12925) are not the same as 

 the holotype of L. erebennus, but are of this new species.
