907 
Dimensions. — Female, length of carapace 48 mm., of abdomen 103 mm. 
Distribution. — Vicinity of Kauai Island, 724 to 1,314 fathoms, stations 4018 (type locality), 4183, 
and 4185. Cat. No. of type, 30540. 
Benthesicymus moratus Smith.

Benthesicymus? moratus Smith, Rept. U. S. Fish Commr. for 1885, 694 [90], 1886. 
Vicinity of Kauai Island, 1,000 to 1,314’ fathoms, station 4185, one male and one female, in poor 
condition. They agree very well with Smith’s description (I have seen no Atlantic specimens) except- 
ing that in the larger, a male about 95 mm. long, the third pleonic segment is not carinate, although 
in the small female (about 55 mm. long) it is obscurely so in the posterior half. 
Benthonectes filipes Smith. 
Benthonectes filipes Smith, Proc. U. S. Nat. Mus., VII, 1885, 509; Rept. U. S. Fish Commr. for 1885, 
692 [88], pi. xvni, figs. 1, la; pi. xix, figs. 1, la, 16, 1886. 
Vicinity of Kauai Island, 508 to 703 fathoms, station 4187; one male. 
In this specimen the rostrum has only one well-developed dorsal spine. In place of the posterior 
one in the figure there is a minute spinule which may represent an aborted spine. 
Gennadas parvus Bate.

Macrura, 340, pi. lix, 1888. Alcock, Desc. Cat. Indian Deep-Sea Crust. 
Dec. Macr. Anom., 46,- 1901. 
Vicinity of Modu Manu, 636 to 850 fathoms, station 4154, one female. 
This specimen has the charac- 
teristic thelycum described by 
Alcock. 
Gennadas propinquus, sp. nov. 
Between Erben Bank and Kaiwi Channel, two 
specimens, male and female, were taken in the inter- 
mediate tow-net at 100 fathoms, which are very close 
to G. parvus Bate, but the thelycum of the female is 
different from that described by Alcock (loc. cit.) . 
A small species (about 32 mm. long), with the 
rostral and the gastric spine very slender, the oph- 
thalmic spine slender, the antennular peduncle with surface pubescent. 
The thelycum shows a large subtriangular shield between the bases of the feet of the third pair, 
followed by a narrow transverse plate and then by a subcordate disk between 
feet of fifth pair. 
The petasma in general form is similar to that of G. parvus Bate (op. cit., 
pi. lix, fig. pp. ), but is differently laciniated across the distal end. 
A mutilated female from vicinity of Kauai Island, 478 to 453 fathoms, 
station 4029, is probably the same species. Cat. No. of type, 30541. 
Gennadas, sp. 
6, Thelycum, x 2§. 
One very soft and damaged male from vicinity of Kauai Island, 1,000 to fig. 62 .—Gennadas, sp., sta- 
1,314 fathoms, station 4185, might pass for G. borealis Rathbun, but the tion 4185 , petasma, - 4 . 
petasma is larger than in that species, and the truncate lobe seen at the 
middle of its distal end (Harriman Alaska Exped., X, 1904, 148, fig. 89a) is replaced by a convex 
margin. The antennal scale appears to be narrower, but is incomplete.
