18 THE VOYAGE OF H.M.S. CHALLENGER. 
Depth in Fathoms. Name. 
80 to 90 Nymphon pallenoides, G. O. Sars, Crustacea et Pyeno- 
gonida nova, Arch. f. Math. og Naturvid., iv., 1879, 
p- 470. Of this species Sars says that it is NV. hirsuto 
affine, sed statura minore, &c. Perhaps it is only a 
local variety. As Sars does not mention the length of 
the auxiliary claws, I feel uncertain whether it is 
nearest to NV. hirtipes, Bell, or N. hirtum, Fabr. 
(Kroyer). 
Nymphon hirtum, Fabr. Entom, Systematica, iv. 417, 
1794. WN. hirtum, Chr. Fabr. (1), Kroyer, Bidrag, &e., 
Nat. Tidskr., N. R. i, 113, 1845. The description 
of Fabricius being quite insufficient, I retain the 
species with the diagnosis of Kroyer. Perhaps J. 
hirsutus, Sabine (Appendix, &c., p. ccxxvi, 1824), 
belongs also to this species ; according to Kréyer this is 
doubtful. WV. hirtum, O. F. Buchholz, Crustaceen der 
Zweiten Deutschen Nordpolarfahrt, 1874, ii. 397. 
In regard to WV. hirtum, Fabr. Heller (Crust., Pyenogon., 
und Tunicaten der K. K. Ost.-Ung. Nordpol. Exp. in 
Denkschr. d. Kais. Akad. d. Wiss., Bd. xxxv., 1875), 
it is impossible to determine whether it is this species 
or NV. hirtipes, Bell, that was observed.

N. brevicaudatum is true, as has been proved by the 
more extensive description with illustrations published 
by Miers in 1879 in the extra vol. of the Phil. Trans. 
of London. Many specimens of this species were 
obtained during the visit of H.M.S. Challenger to 
Kerguelen,
