THE VOYAGE OF H.M.S. CHALLENGER. 
Depth in Fathoms. Name. Geographical Distribution. 
Colossendeis, Jarzyusky (1870). 
No mandibles ; palpi ten-jointed ; ovigerous legs ten-jointed ; proboscis long, cylindrical, 
club-shaped or bottle-shaped.

Jarzynsky, Premissus catalogus Pyecnogonidarum inven- 
tarum in mari glaciali ad oras Lapponice rossice et in 
mari albo, anno 1869 et 70, Annales de la Soc. des Natur. 
de St Petersb., 1870. C. proboscidea, Sabine, G. O. 
Sars, Prodromus descriptionis, &c., Arch. f. Math. 
og Natury., ii. 268, 1877. A gigantic Pycnogonid of 
the higher northern latitudes. 
*Colossendeis megalonyz, u. sp. A well-characterised 
species. In some respects it resembles the C. pro- 
boscidea, Sabine, of the higher northern latitudes ; it 
has, however, a much more slender body and longer legs. 
Colossendeis angusta, G. O. Sars, Prodromus descriptionis, 
&c., Arch. f. Math. og Naturvid., ii. 268,1877. This 
species is the slender Colossendeis of higher northern 
latitudes. 
*Colossendeis leptorhynchus, n. sp. This species seems to 
be avery good one. It is easily recognized by its 
. extremely long and narrow proboscis, of an almost 
cylindrical shape. 
*Colossendeis gigas-leptorhynchus. A single specimen of 
this form was dredged at Station 158. It shows the 
proboscis of C. gigas, whereas the palpi are those of C. 
leptorhynchus. In other respects it resembles both 
species. 
* Colossendeis gigas, n. sp. This seems to be the largest, 
not only of the species of the genus Colossendeis, but 
of all the different forms hitherto described. 
25 Colossendeis kroyerti, Wood-Mason (sp.). Rhopalorhyn- 
chus kréyerii, Wood-Mason, A small but very charac- 
teristic species of the genus Colossendeis. : 
*Colossendeis robusta, n. sp. A beautiful species, easily 
to be recognised by the form of its proboscis, &e. ; 
| *Colossendeis gracilis, n. sp. The species C. media, 
C. brevipes, and C. gracilis, proposed by me, only 
show very slight differences. In regard to C. gracilis, 
I think it is a very interesting fact, that one of the 
specimens is furnished with distinct mandibles. 
* Colossendeis media, n. sp. Characterised by the long claws 
of the legs, and by the peculiar shape of the last joints 
of the palpi.
