DISCUSSION OF SPECIES AND THEIE DISTEIBUTION. 

 MOSELEYA, Goode and Bean, n. g. (Figure347.) 



417, 



Macruriils, having the dorsal sub-continuous; the anal much higher than the second 

 dorsal. Head and snout long, Qadus-Mke; mouth large, lateral, sub terminal. Scales small, 

 not spinigerous, but with about five feeble radiating keels. Ventrals in advance of pecto 

 rals. Vent Tar forward, almost under Last rays of first dorsal. Pectorals and ventrals 

 strong, falciform, the outer ray of each prolonged, that of the ventral exceedingly. Dorsal 

 spine feebly senate. Barbel minute. 



This genus is proposed for the reception of Macrurus longifilis, Giinther (Ann. and 

 Mag. Nat. Hist., 1S77. xx, 439; Challenger Report, xxn, 1887, 151, pi. XXXV), a species 

 obtained by the Challenger at station 235, south of Yeddo, Japan, at a depth of 565 fathoms. 

 The type is 28 inches long, and is admirably figured in the Challenger Report. 



The genus is named in honor of Professor Henry N. Moseley, F. R. 8., of Oxford 

 University, whose contributions to natural history while naturalist of H. M. S. Challenger, 

 we desire to commemorate. 



ABYSSICOLA, Goode and Bean, n. g. 



Macrurids with villiform intermaxillary teeth, uuiserialmandibulary teeth. Dorsal, ven- 

 tral, and pectoral origins nearly iu the same vertical; pectoral very long, spatulate. Dorsal 

 tins separated by a considerable interval. Snout produced, tetrahedral. Interorbital space 

 fiat, wide. Mouth wide, lateral; the intermaxillary shorter than maxillary. 



This geuus is based upon Macrurus macrochir, Giinther, obtained by the Challenger at 

 station 232, on the Hyalonema ground off luosima, Japan, at a depth of 345 fathoms (Giin- 

 ther, Anu. and Mag. Nat. Hist., 1877, xx, -138; Challenger Report, xxn, 1887, 148, pi. xxix, 

 fig. B). The type, which was 27i inches long, is admirably figured in the Challenger 

 Report (Figure 348).

Snout produced into a long depressed process, sharply pointed in front, and with a 

 rather sharp lateral edge, which is continued in a straight line across the infraorbital region. 

 Mouth horseshoe shaped, situated at the lower side of the head. Teeth in both jaws in 

 villiform bands. A barbel. A scaleless fossa on each side of the nape. The second dorsal 

 tin well developed from its begiuuing. Scales of moderate size, more or less spinigerous ; 

 a series of larger scales, ea.eh armed with a projecting ridge along each side of the base of 

 the anterior portions of the dorsal and anal fins. Of the gill-covers the operculum is par- 

 ticularly small. Gill membranes scarcely uuited in front. Four gills with well-developed 

 gill laminae. The first branchial arch is free and provided with short styliform gill-rakers. 

 (Giinther.) 

 Trachyrhynchus longirostris, Giinther, (Challenger Report, xxn, 153, pi. xli, fig. B), was 



taken by the Challenger Northeast of New Zealand, in 1,700 fathoms.
