lateral carina extends backward from the orbital sinus. There is a strong 
hepatic spine at the end of a short carina; also a spine at the outer angle 
of the orbit and an antennal spine. 
Eyes very large, hemispherical, their inner faces flat and contiguous, 
the carinz covering nearly all the outer face. Antennules rather slender; 
the scale at base is small, falcate, and 
acuminate, the second segment about one 
and a half times as long as the third; the 
flagella both exceed the antennal scale, 
the inner is only a little longer than the 
outer. The antennz have a slender spine 
at the outer base of the scale, which is 
narrow-oblong and about three fourths as

reaches to the distal third of the scale, its last joint is very slender, the 
flagellum is about as long as the body. 
The maxillipeds are slender and exceed the scale by nearly half the 
length of the terminal segment. ‘The first pair of feet do not reach the 
end of the scale. The merus has a small superior terminal spine. The 
manus widens a little distally ; its length is three times its width measured 
at the inner base of the spine; the dactylus is more longitudinal than 
transverse. The second and third pairs of feet are equally filiform and 
delicate; the second reaches to the middle or beyond the middle of the 
palm of the first; the third reaches beyond the antennal scale; the fourth 
pair also exceeds the scale; the fifth pair is a little shorter. In the male 
the sternum has a median carina with a small spine on each segment. 
The fifth segment of the abdomen has a low blunt carina; the sixth 
has two prominent dorsal carinz and a low lateral carina on each side 
near the dorsal, but extending only half the length of the segment; the 
telson has a median furrow on its anterior fourth; it exceeds the uropods.
