Name. 
diagnosis of his species says ; unguiculi auxiliares nulli 
(p. 40). A considerable number of specimens of this 
species have recently been dredged (North of Scotland) 
during the cruise of the “ Knight Errant.” One of the 
commonest species in the northern part of the Atlantic. 
(?) Nymphon giganteum, Goodsir, Ann. and Mag. of Nat. 
Hist., vol. xv. p. 298, 1845. Goodsir’s description is 
not sufficient to determine this species. Wilson 
(Pyenogonida of New England, Trans. Connect. Acad., 
vol. v. p. 16, 1880) considers this species as identical 
with the JV. strémii of Kroyer. As Goodsir does not 
even say whether the body is slender or robust, it is 
extremely difficult to ascertain whether or not Wilson’s 
suggestion is right. 
*Nymphon macronyx, G. O. Sars, Prodromus, Arch. f. 
Math. og Naturvid., 1. 365, 1877. I know this 
species by the description of Prof. Sars, from a pencil- 
drawing he kindly sent me, and feel sure it is a good 
species. Recently I had a fair opportunity of becom- 
ing acquainted with it, as numerous specimens were 
dredged north of Scotland, and forwarded to me by Mr 
Murray. As only a very short diagnosis of this 
species has been given by Prof. Sars, I will publish 
hereafter a detailed description of it. 
*Nymphon brevicollum, nu. sp. A fine, well-characterised 
species. 
*Nymphon brachyrhynchus, n. sp. Asmall but well-char- 
acterised species, which seems to abound at a depth of 
45 to 120 fathoms. 
* Nymphon meridionale, n. sp., shows a certain affinity to JV. 
gracilipes, Miers (Ann. and Mag. of Nat. Hist., 4th ser., 
vol. xvi. p. 76, 1875) ; so the latter species may be con- 
sidered as a shore-relation of this true deep-sea species. 
Nymphon gracilipes, Miers, Ann, and Mag. of Nat. Hist., 
4th series, vol. xvi. p.76, 1875. MV. gracilipes, 
Miers, Bohm, Pyen. des Mus. zu Berlin, Monatsb. der 
K. Akad. der Wiss. zu Berlin, p. 170, 1879. W. 
antarcticum, Miers, Crustacea of Kerguelen Island, 
Phil. Trans. Lond., vol. elxviii. Extra vol., p. 
200-214, pl. xi, 1879. This species seems to be a 
good species. Miers thought it necessary to alter the 
name he originally proposed, because in the same year 
the same name was given by Heller to an arctic 
species. The WV. gracilipes, Heller, being only a 
synonym of the WV. *strémii, Kr., I think it best to 
retain this name for the Kerguelen species, as was 
originally proposed by Mr Miers.
