A single specimen, apparently of this species, was taken at Station 307, from 
a depth of 333 fathoms, in Lat. 31° 57’ N., Long. 78° 18’ 35” W. 
It agrees so closely with Schiédte and Meinortia description that I have little 
doubt of its identity with that Mediterranean species, although the body is pro- 
portionally narrower and the segments of the pleon more regularly curved 
above than represented in the figure of 4/7. incisa given by those authors, 
In our specimen the body is nearly three times as long as broad, sparingly 
punctate, well rounded above. 
The head is rounded behind, presenting no ocular lobes; in front it is pro- 
duced into a distinct, pointed process projecting downward between the bases 
of the antennule, separating them and nearly touching the frontal lamina, 
which is small and rhomboidal. The first two segments of the antennule are 
short and small, and rounded in front, not enlarged as in AZ. psora Kroyer; 
the third segment is longer than the first two, and is followed by a slender fla- 
gellum, longer than the peduncle, composed of about fifteen segments, of which 
the first is the longest, being as long as the next two, instead of “ quam secundo 
paulo longiore,” as in the typical specimen of the species. The antenne, when 
reflexed, surpass the second thoracic segment; the flagellum is longer than the 
peduncle, and composed of less than twenty segments. 
The eyes are large, and meet broadly on the median line; ocelli in about ten 
horizontal rows, half of which meet on the median line in front. 
The first thoracic segment is longer than the second, thence they increase 
slowly in length to the fifth or sixth, and the seventh is short. The epimeral 
region of the first segment is marked by an obliquely descending depressed 
line. The epimera are all angulated behind, though only the last two are sen- 
sibly produced, and all are marked by one or two oblique curved lines, running 
downward and backward, the posterior one ending in the lower angle. The 
last epimeron does not attain the lateral angle of the first segment of the 
pleon. The legs are weak, and armed with but few small and short spinules 
throughout. 
All the segments of the pleon are evident, but the first is very short above ; 
the first four are distinctly angulated laterally. The telson is subtriangular, 
distinctly notched behind, as well as minutely crenulated and spinulose. The 
basal segment of the uropods is. produced internally about half the length of 
the inner ramus, which is obliquely elongate triangular, larger and broader 
than the narrowly ovate outer one; both are ciliated and minutely denticulate. 
Length, 13.5 mm.; breadth, 5 mm. 
I have seen no other specimens.
