supra-anal slightly in advance of this line. Different individuals among the cotypes 

 vary with respect to the relation of the supra-anals, some having them in a 

 straight line, others having them very slightly angulated, as in the type. 

 Antero-anals a little curved, the first slightly nearer base of fin. Anals 7 + 3 in 

 the type, and this is the prevailing number in this species. The antero-anals 

 may be seven or eight, the posterior group two, three, or four. On one side 

 of one specimen only six antero-anals were found. One hundred and twenty-six 

 specimens were examined, the two sides being listed separately. In these 6 + 4 

 occurred once, 7 + 2 in five cases, 7 + 3 in one hundred and eighty-nine cases, 

 7 + 4 in seventeen, 8 + 2 in sixteen, 8 + 3 in twenty-four cases. Taking the 

 two groups separately, in the anterior 6 occurred once, 7 two hundred and 

 eleven times, 8 occurred forty times; in the posterior group, 2 occurred twenty- 

 one times, 3 two hundred and thirteen times, and 4 eighteen times. The total 

 number in both groups varies from 9 to 11. One hundred and seventeen of 

 the one hundred and twenty-six specimens were bilaterally symmetrical with 

 regard to their photophores. The first pair of the postero-anals is above the last 

 anal rays. Posterolateral immediately below lateral line, but not in contact with 

 it, sHghtly behind vertical from last antero-anal. Precaudals two, in an oblique 

 line, the interspace very little, if at all, greater than that between the postero- 

 anals. No luminous areas on back, or on inferior surface of caudal peduncle, in 

 any of the numerous adults of the collection. 



Color in spirits uniform dusky brownish on upper parts and on sides of 

 body, profusely dotted with fine black specks. Abdomen and lower side of 

 head silvery. A lengthwise black streak on upper part of pectoral, beginning 

 near base and widening backwards for about the basal third of the length of 

 the fin. 



This is evidently one of the most abundant species in Japanese waters. 

 Numerous adults were obtained from Misaki, on Sagami Bay (C. M. Nos. 

 4614, 4615, 4616) and many immature examples were taken by the "Albatross" 

 at the following Stations: 



4921. West of Colnett Straits. Surface. 



4954. Kurosiwo, east of Kagoshima. Intermediate net, 850 fathoms. 



4955. Kurosiwo, east of Kagoshima. Surface. 



At Station 4954, the specimens probably entered the net at or near the 

 surface. 



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