22 THE VOYAGE OF H.M.S. CHALLENGER.

Depth in Fathoms. Name. Geographical Distribution. 
(2) (1) Nymphon glaciale, Lilljeb., N. glaciale, Lilljeb., | White Sea. 
Jarzynsky, Premissus Catalogus Pyenogonidarum in 
mari glaciali, Annales de la Société des Naturalistes de 
St Petersbourg, 1870. I have never seen a specimen 
of it, nor do I know where the description of Lilljeborg 
is to be found. 
(2) (2) Nymphon femoratum, Leach, Zool. Misc., i. 45, pl. xix. | Channel. 
fig. 2,1814. MW. femoratum, Leach, Milne-Edwards, 
Hist. Nat. des Crustacés, iii. 534, 1840. NV. femor- 
atum, Leach, Johnston, An Attempt &c., Mag. of 
Zool. and Botany, i, 1837. In all probability not a 
good species: description very insufficient; dilated 
thighs are common to the females of almost all the 
species. 
(2) (?) Nymphon pellucidum, Goodsir, Edin. New Phil. Journ., | Coast of England. 
vol. xxxii., 1842. Characterised very insufficiently : 
may turn out to be a variety of NV. brevitarse, Kr. 
(2) (2) Nymphon spinosum, Goodsir, Edin. New Phil. Journal, | Coast of England. 
vol. xxxii., 1842. Like the other species of Goodsir, 
NV. spinosum has been described so very insufficiently 
that it is not to be recognised. 
(?) (?) Nymphon johnstonii, Goodsir, Edin, New Phil. Journal, | Coast of England, 
vol. xxxii., 1842. A very uncertain species. 
(2) (2) Nymphon minutum, Goodsir, Edin. New Phil. Journal, | Coast of England. 
vol. xxxii., 1842. Goodsir’s description is so insuffi- 
cient that the species is not to be recognised. 
(2) (?) Nymphon longiceps, Grube, 46ster Jahres-Ber. der | China Sea. 
Schles. Gesellsch. f. vaterl. Cult. p. 54, 1869. The 
description of this species is so insufficient that it is 
impossible to recognise it. 
B. Species without auxiliary claws.

(* Knight quite agree with G. O. Sars (Prodromus, Arch. for Math. 
Errant”). og Naturvid., ii, 3865, 1877), who places N. hiuns, 
120 to 160 Heller, and JV. abyssorwm, Norman, as identical with 
(Barents Sea, this species. A large and excellent species abounding 
Hoek in MS.). in the higher northern latitudes. The largest haul of 
Pycnogonids, Mr Murray writes to me, he ever saw 
was that in which he got an immense number of speci- 
mens of this species (Cruise of the “ Knight Errant” 
to the north of Scotland, Aug. 1880).
