DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 397 



outer ventral ray produced into a short filament. Distance of the vent from the isthmus 

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



Radial formula: D. 11; A. 115; I'. 21; V. !>. 



This species is known from a single specimen from off the mouth of the Rio dela Plata 

 at a depth of 000 fathoms. Vaillaut identities 1 individuals, taken oil' Morocco iu 2,115- 

 2,200 meters, with this form. 



.1/. zaniapkortis, Yaillant (p. 245), is said by its author to resemble .1/. holotrachys and 

 also M. selerorhynchus. The types were in bad condition, and Vaillant seems to depend 

 upon the scales for his chief diagnostic character. In the absence of a figure we hesitate to 

 admit the species.

 fathoms, and station 171,000 fathoms; and off Japan, station 232, 315 fathoms; south of

Gunther'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 witlt minute spines, giving a granular appearance to their surface. There are live 

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

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

 the vent from the isthmus, equal to the length of the head without snout iu specimens 

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



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



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

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