DISCUSSION OF SPECIES AND THEIK DISTRIBUTION. 417, 



MOSELEYA, Goode and Bean, a. g. (Figure y47.) 



Macmrids, having the dorsal siib-coutiimoiis; the anal much higher than tlic second 

 dorsal. Head and snout long, Gadus-like ; mouth large, lateral, subtenuiual. Scales .small, 

 not spinigerous, but with about live feeble radiating keels. Ventrals in advance (»f pecto- 

 rals. Vent far forward, almost under last rays of first dorsal. I'ectorals and ventrals 

 strong, talciform, the outer ray of each prolonged, that of Mie vc^ntral exceedingly. Dorsal 

 spine feebly serrate. Barbel minute. 



This genus is proposed for the reception of Mmrurtis hnujlfiUs. (liinther (Ann. and 

 Mag. Nat. Hist., 1877, xx, -13'J; Challenger Eeport, xxn, 1887, 151, pi. xxxv), a species 

 obtained by the Challenger at station 235, south of Yeddo, .Japan, at a deptli of .jO."5 fathoms. 

 The type is 28 inches long, and is admirably tigured in the Challenger Uei»ort. 



The genus is named in honor of Professor Henry N. Moseley, F. li. S., 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. 



Macruridswithvilliform i7itermaxillary teeth, uniserialmandibulary teeth. Dorsal, ven- 

 tral, and pectoral origins neaily in the samc^ vertical; pectoral very long, spatulate. Dorsal 

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

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



This genus is based upon Maerunm macrochir, Giinther, obtained by the Challenger at 

 station 232, on the Ilyaloneina ground off Inosima, Japan, at a depth of 315 fathoms (Giin- 

 ther, Ann. and Mag. Nat. Hist., 1877, xx, 438; Challenger Report, xxii, 1887, 1-18, pi. xxix, 

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

 Keport (Figure 318).

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 nai)e. The second dorsal 

 fin well developed from its beginning. Scales of moderate size, more or less spinigerous; 

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

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

 ticularly small. Gill membranes scarcely united in front. Four gills with well-develoi)e<l 

 gill lamin;e. The first branchial arch is free and provided with short styliform gill-rakers. 

 [Oiinther.) 

 Traehijrhynchus longlrostris, Giinther, (Challenger Report, xxii, 153, pi. xl,i, tig. B), was 



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