Nymphon pallenoides, G. 0. Sars, Crustacea et Pycno- 

 gonida nova, Arch. f. Math, og NaturviJ., iv., 1879, 

 p. 470. Of this species Sars says that it is N. hirsuto 

 affine, sed statura minora, &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 iV. hirtipes, Bell, or N. hiiiiun, Fabr. 

 (Kroyer). 



Nijinphon hirtum, Fabr. Entom. Systematica, iv. 417, 

 1794. N. hirtum, Chr. Fabr. (^), Kroyer, BiJrag, &c., 

 Nat. Tidskr., N. E. i. 113, 1845. The description 

 of Fabricius being quite insufficient, I retain the 

 species with the diagnosis of Kroyer. Perhaps N. 

 Jiirgutus, Sabine (Appendix, &c., p. ccxxvi, 1824), 

 belongs also to this species ; according to Kroyer this is 

 doubtfuL N. hirtum, 0. F. Buchholz, Crustaceen der 

 Zweiten Deutschen Nordpolarfahrt, 1874, ii. 397. 

 In regard to N. hirtum, Fabr. Heller (Crust., Pycnogon., 

 und Tunioaten 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 N. hirtipes, Bell, that was observed.

 sition that his A'', hon-idum was indentical with Miers' 

 N. hrevicaudatum 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.^I.S. Challenger to 

 Kergnelen. 

 *Nijmphon stroyiui, Kr., Nat. Tidskr., N. E., vol. i. p. Ill, 

 1845. Wilson (Pycnogonida of New England, Trans. 

 Connect. Acad., vol. v. p. 17, 1880) believes that the 

 N. gracilipes, Heller (Crust. Pycnog. und Tunic, des 

 K. K. Oester.-Ungar. Exped. Denkschr. d. K. Ak. der 

 Wiss., xxxvi., 1875) — not to be confounded with the 

 N. gracilipes, Miers, and therefore named by Bolim 

 (Pycnogoniden des Museums zu Berlin, Monatsb. der 

 K. A. d. Wiss. zu Berlin, p. 170, 1879) TV. Helleri— is 

 very closely allied if it is not identical with this 

 species. This is also my opinion, although Heller in his
