 Jarzynsky, Prremissus Catalogus Pycnogonidarum in 

 mari glaciali, Annales de la Soci6te 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. 



.?) Nymphon feriioratum, Leach, Zool. Misc., i. 45, pi. xix. 

 fig. 2, 1814. N. femoratum, Leach, Milne-Edwards, 

 Hist. Nat. des Crustacfe, iii. 534, 1840. N. femor- 

 atum, Leach, Johnston, An Attempt kc, 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. 



(?) Nijmiihon pellucidum, Goodsir, Edin. New Phil. Journ., 

 vol. xsxii., 1842. Characterised very insufficiently : 

 may turn out to be a variety of N. hrevitarse, Kr. 



(?) Nymplwn spinosum, Goodsir, Ediu. New Phil. Journal, 

 vol. xxxii., 1842. Like the other .species of Goodsir, 

 N. spinosum has been described so very insufficiently 

 that it is not to be recognised. 



(?) Nijmplion johnsfanii, Goodsir, Edin. New PhiL Journal, 

 vol. xxxii., 1842. A very uncertain species. 



"?) Nymphon minutum, Goodsir, Edin. New Phil. Journal, 

 vol. xxxii., 1842. Goodsir's description is so insuffi- 

 cient that the species i^ not to be recognised. 



(.?) Nymphon longireps, Grube, 46ster Jahres-Ber. der 

 Schles. Gesellsch. f. vaterl. Cult. p. 54, 1 869. The 

 description of this species is .so insufficient that it is 

 impossible to recognise it.

 quite agree with G. 0. Sars (Prodromus, Arch, for Math, 

 og Naturvid., ii. 365, 1877), who places N. hiuns. 

 Heller, and N. ahyssorum, Norman, as identical with 

 this species. A large and excellent species abounding 

 in the higher northern latitudes. The largest haul of 

 Pycnogonids, Mr ]\Iurray 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).
