last anal ray. Precaudals widely separated, the first at base of rudimentary 

 caudal rays, the second obliquely above and behind it, on the lateral line. 

 In the largest specimen, 30 mm. long (too badly mutilated to serve as the type), 

 are two luminous spots on the under side of the caudal peduncle. In the type 

 and numerous other smaller specimens, none are developed. Their presence in a 

 specimen 30 mm. long (doubtless a female), indicates that it approaches matu- 

 rity and that the species is a diminutive one. 



General color dusky, as in related species, with little luster. 



List of Stations.

These localities are along the southern coast, from the vicinity of Kago- 

 shima to Suruga Gulf. It was also secured by Mr. Owston in Sagami Bay. 

 The type is deposited in the U. S. National Museum. 



12. Myctophum valdivise Brauer. 

 Mydophum valdivice Brauer, Zool. Anz., Vol. 28, 1904, p. 398, fig. 6. Atlantic 



and Indian Oceans. 



A single badly injured specimen has the upper series of photophores ar- 

 ranged along the dorsal outline, a position unknown in any other species, and 

 is hence identified with M. valdivice. It was taken at Station 4920, south of 

 Kagoshima (30° 34' N., 129° 22' E.), in the open intermediate net down to 300 

 fathoms. 



Genus Centrobranchus Fowler. 

 13. Centrobranchus chcErocephalus Fowler. 



Centrobranchus chcerocephalus Fowler, Proc. Acad. Nat. Sci. Phila., Vol. 55, 



1903 [1904], p. 754; Hawaiian Islands. 



A single young specimen from Station 4921, south of Kagoshima (30° 23' 

 30" N., 129° 36' 30" E.). As usual in this species, the supra-anals are very 

 obliquely arranged, the anterior of the series over the interspace between the 

 second and third ventrals. There are 5 antero-anals and 9 postero-anals, a 

 combination which did not occur in seventy-one specimens reported on pre- 

 viously from the Hawaiian Islands; but both numbers occurred there separately.
