Spirontocaris profunda, sp. liov. 
(PI. xxiv, fig. 10.) 
Carapace stout, carinated in its anterior two-thirds. Rostrum slender, about one-third as long as 
carapace, not reaching end of first antennular segment, horizontal; dorsal spines two, the posterior 
one in line with the supraorbital spine and just in advance of the line of the orbit; one spine below, 
near the tip, which is acuminate. Anterior margin armed with three spines, one supraorbital, one 
antennal, one much smaller at the antero-lateral angle. 
Antennular peduncle two-thirds as long as carapace, first segment twice as long as second, which 
is three times as long as third ; basal scale reaching nearly to end of first segment, which last has on 
its distal margin a spine at the outer angle and two very slender ones above; antero-external angle of 
second segment armed with a slender spine, of third segment with two spines. Flagella about as long 
as peduncle. 
The antennal scale exceeds the antennular peduncle, its blade is oblique and overreaches the 
spine; the peduncle reaches to the end of the second antennular segment. Flagellum as long as the 
body less the telson. 
Outer maxillipeds stout and very long, extending beyond acicle by length of last joint and nearly 
half of the penult. They are without exopod, but have an epipod as have also the first three pairs of 
trunk legs. The stout first pair extend to middle of terminal joint of maxilliped; the second pair are 
a little longer than the first; carpus of nine segments. 
Fifth and sixth abdominal somites armed with a postero-lateral spine; fifth one and a half times 
as long as sixth segment; telson as long as fifth and sixth together, with four spinules on one side and 
five on the other. 
Dimensions. — Female, length 46, of carapace and rostrum 15, of rostrum 4.3 mm. 
Typelocality. -Vicinity of ModuManu, 762 to 1,000 fathoms, station 4157; 1 female (Cat. No. 30546). 
This species is near S', washingtonicma Rath-bun, found in deep, water off the State of Washington, 
but has a much shorter rostrum and longer maxillipeds.
