BRACHYURA AND MACRURA OF HAWAIIAN ISLANDS. 
915 
This species can be most readily distinguished from the preceding, P. martins, by the median 
spine on the posterior border of the third abdominal segment and the greater length of the sixth seg- 
ment, which is longer than the telson. The last three pairs of legs are also appreciably shorter. 
Less abundant than P. martius, only 128 specimens having been taken in twenty-eight hauls. 
Color. — Ground tint pearly or milky semiopaqueness, the viscera clearly showing through the 
thorax. End of rostrum, tips of legs and abdomen at edges of joints vermilion. Spots of same color 
along sides of abdomen; terminal half of abdomen finely dotted, and telson marked with vermilion. 
Distribution. — Kaiwi Channel, 220 to 346 fathoms, stations 3467, 3472, 3473, and 3893; south coast 
of Oahu, 228 to 369 fathoms, stations 3815, 3914, 3920, and 3922; Pailolo Channel, 256 to 684 fathoms, 
stations 3865, 3868, 3883, 3884, and 3901; vicinity of Laysan, 351 to 347 fathoms, station 3952; vicinity 
of Kauai, 55 to 469 fathoms, stations 3986, 3988, 3990, 3998, 4130, 4131, 4132, 4134, and 4135; north 
coast of Maui, 253 to 283 fathoms, stations 4084 and 4085; northeast approach to Pailolo Channel, 290 
to 286 fathoms, station 4095; northeast coast of Oahu, 282 to 253 fathoms, station 4117; vicinity of 
Niihau Island 319 to 378 fathoms, station 4178. 
? Pandalus ocellus (Bate). 
(Pl. xxx, fig. 1.) 
Nothocaris ocellus Bate, Challenger Macrura, 657, pl. cxiv, fig. 3, 1888. Not ? Pandalus ( Plesionika ) 
ocellus Alcock, Desc. Cat. Indian Deep-Sea Crust. Dec. Macr. Anom., 97, 1901. 
I am in doubt as to the identity of this form with Bate’s; it seems much nearer to his figure and 
description than does the Andaman specimen placed here hesitatingly by Alcock. 
The only discrepancy of any consequence is this, that the feet of the second pair are equal and 
similar, while, according to Bate, the left carpus is nearly twice as long as the right. Whether this 
has been correctly reported or not remains to be seen. 
In the Hawaiian specimens the two posterior dorsal spines are small, close together, and movable; 
then follow about six larger and moi~e separated fixed spines, and then from four to six very small fixed 
and still more distant spines which reach to the tij>; below are seven or eight small fixed spines which 
begin a little in front of the antennular peduncle, which is farther back than Bate describes them. It 
must be remembered that he had only two specimens, and only one with rostrum. 
The second pair of feet overreach the maxillipeds by the length of the chela and seven or eight 
joints of the carpus. The third, fourth, and fifth pairs of feet diminish in length in the order named; 
the third exceeds the maxilliped by the dactylus, propodus, and three-fourths of the carpus; the fifth 
reaches to end of proximal third of propodus of third. 
Distribution. — South coast of Molokai Island, 115 to 134 fathoms, station 3853; Pailolo Channel, 
122 to 143 fathoms, statipns 3856, 3858, 4101, 4102, 4103, and 4104; Auau Channel, 126 to 130 fathoms, 
station 3896; vicinity of Kauai Island, 230 to 53 fathoms, station 4002; north coast of Maui Island, 45 
to 52 fathoms, station 4070. 
Pandalus sindoi, sp. nov. 
(Pl. xxi, fig. 4.) 
Near the preceding, P. ocellus. Differs in having the posterior four (instead of two) dorsal spines 
small, subequal and close together, although only the posterior two or three are movable. Eyes 
considerably larger. Antennular peduncle not reaching to end of second segment of antennular 
peduncle. Second pair of feet overreaching tip of maxilliped very slightly, not more than length of 
chela. Sixth abdominal segment longer, twice as long as fifth segment; telson correspondingly 
elongate. . ' 
Named for M. Sindo, of the Fish Commission party of 1901. 
Only three adult specimens were taken, all fragmentary; two male (type, Cat. No. 30547) from 
station 3998, vicinity of Kauai Island, 235 to 228 fathoms, and one female, station 3953, vicinity of 
Laysan Island, 347 to 264 fathoms; also one young from station 3846, south coast of Molokai Island, 
64 to 60 fathoms. 
Dimensions. — Length of male 58, length of carapace 10.4, rostrum 16.2, abdomen 32.4, sixth 
abdominal segment 7.6, telson without terminal movable spines 7.5 mm. Length of larger male, 
exclusive of rostrum which is broken, 52.5 mm. 
This may be Pandalus ( Plesionika ) ocellus Alcock non Bate (Desc. Cat., p. 98) of which there was 
only a single specimen, lacking the right leg of the second pair.
