marginal pair ending in spines. Telson with 
high median carina ending in a short terminal 
spine, submedian, intermediate, second lat- 
eral, and marginal carinae; armed with three 
pairs of strong marginal teeth, submedian 
(with movable tips), intermediate, and lateral; 
no submedian denticles but a series of minute 
spinules, two intermediate denticles, and a 
single lateral denticle. Exopod of uropods 
with 10 or 11 movable spines on outer margin. 
Basal portion of uropods elongated into two 
spines, inner shorter than outer. First abdom- 
inal appendage of male shown in Figure 19/ 
Color of the specimens is a uniform light 
yellowish pink above with the exposed thor- 
acic and first four abdominal somites having 
a light pink posterior margin. The large glob- 
ular eyes are dark brown and the flagella of 
the antennae are pink. The animals are quite 
small with the reported range in length from 
27 to 80 mm. 
DISCUSSION: In dorsal aspect this species 
very closely resembles small specimens of 
Psuedosquilla, but the ischio-meral articulation 
of the raptorial claw and the large globular 
eyes are suitable for distinguishing members 
of this genus from those of Pseudosquilla. The 
inflated dactylus and the ischio-meral articula- 
tion of the raptorial claw are features which 
members of this genus have in common with 
Gonodactylus, but the numerous carinae on the 
telson, the nonpectinate upper margin of the 
raptorial propodus, and the series of teeth on 
the inner margin of the raptorial dactylus will 
serve to separate this group from the latter. 
As stated by Bigelow (1894) this genus seems 
to occupy an intermediate position between 
Gonodactylus and Pseudosquilla. 
Five female and three male specimens of 
this species have been examined, all of which 
were taken from stomachs of the skipjack, 
Katsuwonus pelamis, and of the yellowfin tuna, 
Neothunnus macropterus. The Bishop Museum 
has one male and two females which were 
dredged off Waikiki, Oahu, at a depth ranging 
from 30 to 50 fathoms. Pocock’s (1893) type 
specimen was a single female from the Mac- 
clesfield Bank, South China Sea, at a depth 
of 35 fathoms. Bigelow (1931) reported four 
males, one female, and two juveniles taken 
in Hawaiian waters by the "Albatross” in 
1902 at depths ranging from 24 to 83 fathoms. 
The specimens which I have examined are in 
agreement with those previously reported. 
Some characteristics were relatively difficult 
to distinguish, but I attribute this to the fact 
that the animals were considerably disfigured 
from having been in the stomach. Edmondson 
(1921) has illustrated the telson of this species 
more clearly than is shown in Figure 18. 
There appears to be no distinct sexual di- 
morphism. The first abdominal appendage of 
the male shown in Figure 19/ is incomplete 
because the fixed limb in all three specimens 
was indistinguishable.
