BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Family LYSMATID^. 
Processa processa (Bate). 
(PI. xxix, fig. 6.) 
Nika processa Bate, Challenger Macrura, 527, pi. xcv, 1888. 
Distribution. — Honolulu Beef, May 8, 1902; Auau Channel, 21 to 43 fathoms, stations 3872 and 
3874. Six specimens in all. 
The rostrum is compressed, carinate, as long as eye, extremity oblique, bispinose, a shorter spine 
above, longer one below, a few hairs between. 
The eyes are very large, flattened, and have a small but distinct and dark-colored ocellus on the 
border of the cornea and mainly outlined 'against the peduncle. The antennular peduncle is as long 
as the acicle; the antennal peduncle reaches just to end of basal joint of antennular peduncle. 
The outer maxilliped and the simple foot of the first pair exceed the acicle by length of their last 
segment, while the cheliped of the first pair is barely as long as the acicle. 
Feet of second pair unequal; right foot exceeding acicle by half its merus besides- carpus and 
chela, merus feebly subdivided, carpus with about 65 segments; left foot exceeding acicle by length of 
chela and nearly all the carpus, merus also feebly segmented, carpus with thirty subdivisions. 
A specimen from station 3876 presents a curious variation; the small upper spine of the rostrum is 
found much farther back, at the middle of the rostrum, which from that point tapers anteriorly in a 
long acuminate spine. 
Processa hawaiensis (Dana). 
Nika hawaiensis Dana, Crust. TJ..S. Expl. Exped., I, 538, 1852; atlas, pi. xxxm, fig. 7 a-h, 1855. 
Lahaina, Maui (Dana). 
According to Dana the rostrum is shorter than the eyes and broader than long; the antennular 
peduncle longer than acicle; antennal peduncle nearly as long as acicle. Carpus of feet of second pair 
with eleven joints. 
Family HIPP0LYTID7E. 
Hippolyte acuta (Stimpson). 
(PI. xxiv, fig. 3.) 
Virbius acutus Stimpson, Proc. Acad. Nat. Sci. Phila., XII, 1860, 104 [35]. 
Reef in front of Honolulu, August 16, 1901, one ovigerous female; one additional ovigerous female 
without label was taken in 1901. 
These agree very well with Stimpson’ s description, except that the telson is armed dorsally with 
only two pairs of aculei. 
Hippolysmata acicula, sp. nov. 
(PI. xxiv, fig. 6.) 
Differs from H. vittata Stimpson, of which I have seen no examples, in the longer antennal scale, 
which exceeds considerably the antennular peduncle and is nearly as long as the carapace, rostrum 
excluded; in the outer maxilliped exceeding the acicle by only the half of its terminal joint; in the 
greater number of segments (29) of the carpus of the second pair of feet. 
The rostral formula is the rostrum reaching to the distal third, as in the largest specimen, or 
to the end, as in smaller specimens, of the penult segment of the antennular stalk; two teeth are on 
the carapace, the posterior in front of middle. The antennal flagellum is sometimes nearly twice as 
long as body; in the largest specimen it is broken off. 
Dimensions. — Female type, length 27.8, length of carapace with rostrum 9.8, without rostrum 6.8., 
length of acicle measured on outer margin 5.8 mm. 
Distribution. — Vicinity of Kauai Island, 7 to 148 fathoms, station 3999, 1 female type (Cat. No. 30544) ; 
Honolulu, from bottom of tugboat, July 3, 1902, 4 specimens.
