DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 397 



outer ventral ray produced into a short filament. Distance of the veut from the isthmuKS 

 equal to tlie length of the liead without snout. Barbel very small. No bands or spots. 



Radial formula: D. 11; A. 115; P. 21; V. 9. 



This species is known from a single specimen from oil' the mouth of the Eio de la Plata 

 at a depth of GOO fathoms. VaiHant identifies 4 individuals, taken off Morocco in 2,115- 

 2,200 meters, with this form. 



M. zania2)hurus, Vaillant (p. 245), is said by its author to resemble 31. holotrachys and 

 also M. sclerorhynchm. The types were iu bad condition, and Vaillant seems to depend 

 u])on the scales for his chief diagnostic character. In the absence of a figure we hesitate to 

 admit the species.

A genus with characters of Macrurus, with teeth in villiform bands above and below,

 ing the interior region into vertical and subhorizontal portions. Dorsal spine smooth. 



Ccelorhynclius panillelKSjGuuther (Challenger Report, xxii, 125, pi. xxix, Fig. A) was 

 taken off New Zealand, station 109, 700 fathoms; off the Kermadecs, station 170A, 630 

 fathoms, and station 171, 600 fathoms; and oft" Japan, station 232, 345 fathoms; south of 

 Japan, station 235,565 fathoms; and also by the Investigator in the Gulf of Manaar, iu 697 

 fathoms.

Giintlier's revised description is as follows : 



Snout moderately produced, angular iu front, a little shorter than or equal to the eye, 

 the diameter of which is one-third of the length of the liead. IScales of moderate size, 

 covered with minute spines, giving a granular api)earance to their surface. There are five 

 or six scales iu a transverse series, between the first dorsal fiu and the lateral line. (A 

 naked space between the ventrals.) Dorsal spine smooth. Abdomen, that is, distance of 

 tlic vent from the isthmus, equal to the length of the liead without snout in specimens 

 about 12 inches long. Outer ventral ray produced into a short fihiment. 



Kadialfonnula: D. 10; A. 7.^-SG; P. 20; V. 7. 



This species is very closely related to Macrurus carminatus, Goode. It was originally 

 described from a specimen in the Turin Museum, probably collected by Donati on Lis
