of articles (starting from ischium) as 10:10:11: 
10:3 (the last two ratios referring to palm and 
fingers, respectively ) . 
Carpus of second legs with first article 5 times 
length of second, second slightly shorter than 
fifth, third and fourth subequal and shorter 
than second. 
Third to fifth legs elongate and slender. 
Ischium of third leg 5 times as long as broad, 
0.66 as long as merus, and armed with two 
movable spines; merus 6.7 times as long as 
broad, unarmed. Carpus 0.8 length of merus, 
almost 10 times as long as broad distally, dis- 
tally armed with movable spine on inferior 
margin. Propodus slightly longer, slightly thin- 
ner than carpus, bearing three slender spines on 
inferior margin, with the longest spine distal. 
Dactylus simple, slightly curved, tip acute, 7 
times as long as broad at base, half the length 
of the carpus, and bearing a tuft of fine setae 
two-thirds of distance to tip. Brush on fifth legs 
poorly developed. 
Telson 5.6 times as long as posterior margin 
is broad, 2.6 times as broad anteriorly as pos- 
teriorly; posterior cleft trapeziform, narrow, 
and shallow; terminal spines heavy, middle pair 
1.6 times as long as posterior margin is broad; 
cleft bearing single pair of setiferous bristles; 
dorsal spi miles slight. Uropods slender, longer 
than telson; tooth on outer uropod heavy, reach- 
ing to end of squamous portion. 
DISCUSSION: It was unfortunate that this 
single specimen was not more nearly intact, and 
that the small chela and second legs were lost 
after the initial examination. However, because 
its form is so distinctive we have decided to 
describe it as a new species. 
All of the characteristics available- — the gen- 
eral body form, the development of the rostrum 
and supraorbital teeth, the form of the smaller 
chela, and the form of the telson— indicate that 
the species belongs to the genus Salmonem. It 
also lacks the anal tubercles and has the artic- 
ulated pleura of the sixth abdominal segment, 
as is characteristic of Salmonem , and it has a 
branchial formula (5-1-8) of the genus. But 
without the final confirmation that can be ob- 
tained only from examination of the large chela, 
this assignment to genus must be provisional. 
Within the genus it is similar to no species 
in that the rostrum is so much longer than 
broad, in the exposure of the corneas dorsally 
and laterally, in the angle of the orbital teeth, 
and in the extreme elongation of the third legs. 
While the form of the posterior notch of the 
telson and the lack of carinae on the carapace 
is similar to S. sibogae , not enough is known 
about the members of this genus to hazard a 
guess as to interspecific relationship. 
This species Is named in honor of Miss 
Tafaonga Uitirne (now Mrs. Stewart), then a 
school teacher at Yailutai, Upolu, who served 
as an interpreter in the village and arranged for 
helpers and outrigger canoes during the collect- 
ing there.

DISCUSSION: Because this specimen, the only 
one of this species in the collection, has only 
one third and one fourth leg intact posterior 
to the maxillipeds, it cannot be identified except 
tentatively. However, in those parts which are 
intact it agrees well with both Stimpson s orig- 
inal description, with Hale’s short note, and 
with the description of Alpheopsis species by 
de Man. The chief difference between this speci- 
men and that described by de Man is that in 
this oiie the telson is 3-5 times as long as the 
posterior margin Is broad, and de Man states
