Name. 



Geographical Distribution. 



PiAllene, Johnston (1837). 



Mandibles cheliform ; palpi wanting ; ovigerous legs ten-jointed, present in both .sexes. The 

 last four joints of the ovigerous legs often furnished with denticulate spines. 



Pallene hrevirostris, Johnston, An Attempt to ascertain, 

 &c., Mag. of Zool. and Bot, vol. i. 1837. P. 

 hrevirostris, Johnston, Grube, Mittheilungen iiber St 

 Vaast la Hougue, &c., Verhandl. der Schl. Ges. f. 

 vaterl. Cultur., 1859. P. hrevirostris, Johnston, Hoek, 

 Ueher Pycnogoniden, Niederl. Arch. f. Zool., iii., 

 1877. A well-characteri.sed species. 



C!) Pallene empusa, "Wilson, Pycnogonida of New England, 

 Trans. Connect. Acad., vol. v. p. 9, 1880. This 

 species is so closely allied to P. hrevirostris, John- 

 ston, of the European coast, that it must be considered 

 either as the same, or as a variety of that species. 



(1) Pallene chelifera, Claparede (sp.), Beobachtungen iiber 

 wirbellose Thiere, p. 103, 186.3. Claparede gives a very 

 insufficient description of this species, which he con- 

 siders as a Plwxichilidivm. I think it most probable, 

 that it is closely allied to P. hrevirostris, Johnston. 

 Pallene spinipes, Fabr. Ptjcnogoniim spinipes, Fabr. 

 (sp.). Fauna GronI, p. 232. Pallene spinipes, Fabr., 

 Kroyer, Bidrag til Kundskab, Naturhist. Tidskr., Ny 

 Eaekke, i. 118, 1845. Pallene spinipjes, Fabr., Jar- 

 zynsky, Prsemissus Catalogus, Annales de la Soc. des 

 Natur. de St Petersb., 1870. 

 *Pallene Imvis, n. sp. A well characterised Pallene species. 

 Pallme chiragra, Milne-Edw., Histoire Natur. des 

 Crustacfe, torn. iii. p. 535, 1840. The description of 

 this species given by Milne-Edw., loe. cit., is insufficient. 

 Perhaps it is the same as the species for which T propose 

 the name P. australiensis. 

 *Pallene australiensis, n. sp. Perhaps it is this species, 

 which has been described by Milne-Edwards as P. 

 chiragra (Hist. Nat. des Crust., iii. 535, 1840). 

 Pallene gruhii, Hoek. I propose this name for the 

 species described by Grube (Jahresb. der Schles. Ges. f. 

 vaterl. Cultur., p. 54, 1869), and which Grube con- 

 sidered as a species of Phoxichilidivm. 

 Pallene longiceps, Bcihm, Sitzungsber. des Ges. naturf. 

 Freunde zu Berlin, p. 59, 1879. A very curious species 

 with rudimentary two-jointed palpi in the male sex. 

 *Pallene languida, n. sp. Nearly allied to P. longiceps, 

 Bohm (Sitzungsber. des. Ges. Naturf. Freunde in 

 Berlin, 1869). 



Northern Europe (Coast of 

 England, France, of the 

 Netherlands).

 necticut (U. S. A.).
