The gills and viscera are situated far forward. The gills are short, 

 broad, blunt, with many crowded lamellae. The stomach has a 

 short, thick, tapering, saccular appendage. The liver is relatively 

 large, short, rounded. Rectum slender, with two well-developed, 

 spatulate anal papilht;. Bianchial auricles well-developed, oblong. 

 The pen is very thin and delicate. 



Station 2037, in 1731 fathoms, N. latitude 38° 53', W. longitude

The only described species which resembles this is Loligopsis ver- 

 micolaris Riip., but the latter, if the figures can be relied upon, differs 

 in its proportions. It has a still longer and more slender head, while 

 its caudal fin is much larger and has a distinctly cordate outline, 

 broadest across the anterior lobes, which are much larger and broadly 

 rounded. It is, however, evidently congeneric with our species, and 

 should be called Leptotenthis vermicolaris. 



Our specimen has the reproductive organs but little developed, and 

 is, therefoi'e, probably immature.

Plate XXVIII, figure 2. 



The following description is from the type-specimen, in alcohol. 



Small, eyes large; caudal fin, about two-thirds as long as the 

 mantle, and much broader than long, transversely elliptical ; 2d and 

 3d pairs of arms equal; dorsal a little shorter; ventrals shortest. 

 Sessile arms with two rows of hooks, which are replaced by small 

 suckers on the distal third ; tentacular clubs with two alternating- 

 rows of hooks, and with marginal suckers distally, on each side?
