96 MEMOIRS OF THE CARNEGIE MUSEUM 



between eye and nostril, expanding a little above the nostril, scarcely extending 

 on the ventral aspect of the orbit; no trace of a suborbital. Suprapectoral 

 immediately above angle of opercular flap, its distance from lateral line two- 

 thirds its distance from base of upper pectoral ray (slightly lower in a cotype); 

 the usual glandular body is attached to it below. None of the pectoral organs 

 are concealed beneath the opercular flap. Fourth thoracic a trifle above the 

 level of the ventral base, nearly verticallj^ above the third thoracic. Supra- 

 ventral nearer lateral line than base of ventrals. Third ventral not greatly 

 elevated, a little below the oblique line joining first and second, not as high as 

 the middle supra-anal. Supra-anals slightly angulated, the second a little in 

 advance of the line joining the other two; the upper one is below the lateral 

 line and in contact with it, the lower above and slightly behind the fifth ventral. 

 First antero-anal greatly elevated, nearly vertically above the second, on a level 

 with middle supra-anal, its distance from second much greater than that between 

 second and third, and equaling that between third and fifth. Second to sixth 

 antero-anals in a straight line, parallel with anal base, the seventh elevated, the 

 line joining sixth and seventh passing just behind the posterolateral, which is 

 in contact with the lateral line. Postero-anals 5. Last precaudal a little below 

 the end of the lateral line, the first two horizontal, at lower edge of tail, the 

 third a little above them. 



General color very dark, the mouth and gill-cavity black; vertical fins with 

 the rays black-dotted. . The anals vary from 6 to 7 + 5 to 6. 



Several cotypes from Sagami Bay (C. M. No. 4605). The type is de- 

 posited in the Carnegie Museum. 



23. Diaphus sagamiensis sp. nov. (Plate XIII, fig. 2.) 

 Type 67 mm. in total length, 53 mm. to base of caudal, from Sagami Bay, 

 Japan, collection of Alan Owston (C. M. No. 4608). 



Most nearly related to D. signatus Gilbert, but with the lower pre-orbital 

 extending along the ventral border of the orbit to vertical from posterior border 

 of pupil, the supraventral photophore midway between lateral line and base of 

 ventrals (decidedly nearer lateral line in D. signatus), the first antero-anal less 

 elevated, the second much less widely spaced from third, and the precaudals 

 less widely spaced, the fourth lower. The photophores are larger, and the form 

 deeper. It differs also from D. coeruleus and D. splendidxis, in the ventral, 

 continuation of the lower pre-orbital, and in details of position and spacing of 

 the photophores.
