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

This species is known from a single specimen from olf the mouth of the Kio de la Plata 

 at a depth of 600 ftithoms. Vaillant identifies 4 individuals, taken off Morocco in 2,115- 

 2,200 meters, with this Ibrm. 



31. zuHiaplioriis, Vaillant (p. 24.5), is said by its autlior to resemble 3f. hnlotracln/s and 

 also M. sclerorhynohm. The types were in 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.

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

Giinther's revised description is as follows: 



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

 the diameter of which is one-third of the length of the head. Scales of moderate size, 

 covered with minute spines, giving a granular appearance to their surface. There are five 

 or six Scales in a transverse series, between the first dorsal fin and the lateral line. (A 

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

 the vent from the isthmus, equal to the length of the Iiea<l without snout in specimens 

 about 12 inches long. Outer ventral ray produced into a sliort filament. 



Radial formula: D. 10; A. 75-80; P. 20; V. 7. 



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

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