REPORT ON THE PYCNOGONIDA. S 



The species of the English coast found (1842-44) a new monographer in Goodsir,* 

 who in three consecutive papers enumerates a large number of species new to the fauna 

 of the British Isles and to science in general. Two new genera {Pephrcdo and Pasithoe) 

 are proposed by him, but owing to the want of detail jVIi- Goodsii-'s papers are of little 

 value, for it is absolutely impossible to recognise either his new genera or his new species 

 from such descriptions as he gives. 



Of as little value is the list given by Hodge (1864),- in which all Goodsii-'s species 

 are found, in addition to some new Ammotheas and species of his new genus Achelia. 

 Since Hodge's list — though occasionally in English periodicals short descriptions of new 

 species have been published — no special paper on the Pycnogonids of the English coast 

 has appeared. 



Those of the Norwegian coast found a very able describer in Kroyer (1845),^ who 

 gives very clear diagnoses of the genera and species. As a new genus he proposes 

 Zetes, and the total number of species described by him is twelve. These descrip- 

 tions were published without illustrations ; but illustrations to the text may be found 

 in Quoy and Gaimard's Voyages en Scandinavie, Laponie, &c., Zoologie, Crustaces, 

 pi. xxxix. (1840). 



For the Pycnogonids of Northern Europe and the coasts of the Arctic Ocean, liesides 

 Kroyer, the following authors must be mentioned: — Otho Fabricius* for the coast of 

 Greenland, as mentioned above. Sabine' (1824) describes two Nymphons {N. cjrossqKS and 

 N. liirmtum) and a species of Phoxichilus {P. proboscideus — a true Colossendeis, Jar- 

 zynsky), found on the shores of the North Georgian Islands. Bell (1855)," in Belcher's 

 Last of the Arctic Voyages, gives descriptions and drawings of two new species of Nym- 

 phon {N. hirtipes and N. rohustum) common in higher northern latitudes. Jarzynsky (1870)' 

 enumerates the species of Russian Lapland and the White Sea. A new genus (Colos- 

 sendeis) is proposed by him. Buchholz (1874),' in the narrative of the second German 

 North Polar Expedition, enumerates three species of Nynvplion, but none of these are new.
