by the greater number of rays in first dorsal, pectorals, and ventrals, 

 and the armature of the scales. 



MACROURUS PARVIPES Smith and Radcliffe, new species. 

 Plate 28, fig. 1. 



Plrst dorsal ii,S (tail mutilated); ventrals 6; pectorals 18. 



Head 1.31 in distance from tip of snout to anal, short, slightly 

 arched, not as wide as deep, bony framework not very firm, mter- 

 osteal tissue badly shrunken in alcoholic specimen; suborbital ridges 

 and rostral edges sharp, prominent; body short, compressed, greatest 

 depth at origin of dorsal 1.80 m distance between tip of snout and 

 origin of anal; vent immediately in front of anal; tail very long, 

 strongly compressed, filamentous in examples in which it is complete; 

 eye 4.08 in head, small, subcircular; interorbital 3, broader than eye, 

 slightly arched; snout 2.75, rather short, depressed, a distinct angu- 

 lation on sides, as in species of Matxocephalus; from point of angu- 

 lation the snout narrows rapidly, the margin being slightly concave 

 in the alcoholic specimen, tip pointed, the well-developed groove 

 along anterior margui found in species of Matseoceplialus lacldng; 

 mouth rather small, well forward, an eye diameter from tip of snout; 

 maxillary 3.64, scarcely as long as distance between tips of maxillaries 

 posteriorly; teeth small, villiform, in bands, narrowing posteriorly, 

 outer row of teeth in upper jaw scarcely enlarged; barbel mmute, 

 scarcely as long as pupil; scales smaU, 10 from origin of dorsal to and 

 mcluding lateral line, each scale armed with about 15 slender spinules 

 not very regular m their arrangement, spinules of scales of head much 

 larger than those on body; under side of head scaled. 



Tip of snout to origin of dorsal 1.17 in distance to anal, first spine 

 small, second 1.30 in head, armed with small, slender spinules; inter- 

 dorsal space 3 in head; second dorsal low, not as well developed as 

 anal ; origin of anal under posterior rays of first dorsal ; ventrals small, 

 rays in reduced number, outer ray longest, about 0.33 as long as head: 

 pectorals 2.21 in head, small. 



Color in alcohol: Tail and upper part of trunk wood-brown; top 

 and sides of head hair-brown; under side of head and body to twelfth 

 anal ray dark clove-brown; fins dusky. 



Ty 2)6.— Cut. No. 72941, U.S.N.M., 22.8 cm. in length, taken with a 

 beam trawl at station 5636 (lat. 1° 55' 00" S.; long. 127° 42' 30" E.). 

 near Gomomo Island, Dutch East Indies, at a depth of 1,262 fathoms, 

 on a bottom of gray mud and fine sand. 



This species was taken by the Albatross at depths of 1,089 to 1,262 

 fathoms.
