of Molokai Island, 328 to 414 fathoms, station 3892; vicinity of Kauai Island, 165 to 881 fathoms, 
stations 3985, 3988, 3989, 3997, 4013, 4014, 4015, 4019, 4020, 4021, 4028, 4029, 4137, 4138, 4140, 4141, 4142,

Nematocarcinus gracilis Bate. 
Nematocarcinus gracilis Bate, Challenger Macrura, 815, pi. cxxxii, fig. 8, 1888. Alcock, Desc. Cat. 
Indian Deep-Sea Crust. Dec. Macr. Anom., 90, 1901. 
Rostrum one-third as long as carapace, teeth ^- 2 , about seven of the dorsal spines on the carapace 
proper. Telson with its long terminal spines exceeds outer uropods. The antennular peduncle 
reaches a little beyond middle of acicle. Three-fifths of carpus of first pair of feet extend beyond aci- 
cle. Three hind pairs much longer than body, exceeding the latter by nearly one-fourth their length. 
This species differs from N. cursor A. Milne Edwards much as N. tenuirostris Bate does from N. 
ensiferus (Smith); that is, in its more numerous and more closely set rostral teeth, and much longer 
legs. 
Distribution. — South coast of Molokai Island, 430 to 371 fathoms, station 3826; north coast of Molo- 
kai Island, 295 fathoms, station 3904; south coast of Oahu Island, 294 to'330 fathoms, stations 3916 and 
3917; French Frigate Shoal, 395 to 397 fathoms, station 3973; vicinity of Kauai Island, 165 to 703 
fathoms, stations 3983, 3985, 3988, 3989, 3992, 4022, 4137, and 4187; Kaiwi Channel, 350 to 433 
fathoms, stations 4107 and 4113. 
Family STYLODACTYUDAi. 
Stylodactylus discissipes Bate. 
(PI. xxiii, fig. 1.) 
Stylodactylus discissipes Bate, Challenger Macrura, 851, pi. cxxxvm, fig. 1, 1888. 
Vicinity of Kauai Island, 230 to 53 fathoms, station 4002; 1 female. 
The dimensions are as follows: Rostrum 9, carapace 6.6, entire length 33.3 
mm.; antennal flagellum 66 mm. Rostral formula A)- ; the ventral teeth are 
at irregular intervals, as if the normal number were greater. Surface of cara- 
pace densely and finely punctate, and with a deciduous pubescence. 
Of the five pairs of lateral spines on the telson the posterior pair is almost 
in line with the posterior median spine; beneath the latter and across the end 
of the segment are two pairs of very long movable spines, of which the inner 
pair is three-fifths as long as outer pair. 
Family PASIPHiEID£. 
Pasiphaea kaiwiensis, sp. nov. 
(PI. xxiii, fig. 4.) 
Length of carapace contained in length of abdomen from two and two-thirds to two and four-fifths 
times. Carapace not carinate except at the anterior tooth, which is triangular, dentiform, with a 
spiniform tip, and does not reach the level of the anterior margin of the carapace. Branchiostegal 
spine situated over the anterior end of the branchiostegal sinus. 
Abdomen not carinate; although the sixth segment is much compressed, it is very blunt and 
smooth above. Telson about three-fourths as long as sixth segment, its tip cut in a very shallow V. 
Eyes considerably enlarged distally. Antennular peduncle reaching a little past middle of acicle, 
which is slightly more than half length of carapace.
