On Vermes collected in the Sea of S^itzhergen. 53 On comparing the above measurements with those of the European species, it appears that the latter has a longer bill and tarsus. The females of the two species, as might be expected, do not differ very conspicuously ; but that of the American bird is much larger in size, and exhibits the same difference in the nasal ridges. VII. — On the Vermes collected hy M. von Heuglin in the Sea of Spitzhergen. By Prof. Ehlees*. The catalogue here given, as regards the Chaetophorous An-nelides, supplements Malmgren's admirable memoirs (" Nor-diska Hafs-Annulater," (Efvers. af K. Vet. Akad. Forhandl. 1865, and 'Annulata polychseta,' Helsingfors, 1867), which have disclosed to us the Annelidan fauna of the Arctic Sea. The names employed by Malmgren are therefore retained here, without, however, any intention of thus expressing an uncon-ditional acceptance of the numerous genera established by Malmgren, Annelida polychjeta. ^^^Nychia cirrosa (Pall.). Storfjord (Wybe Jans Water). Harmothoe imbricata (L., Malmgr.). StonQord. Numerous examples and many colour-varieties. Antinoe Sarsii (Kinb.). Storfjord. Zweigletscherbucht (Mohn Bay). This species, of which there are numerous specimens, occurs in two races definitely separated by difference of colour ; and as Malmgren only mentions one of these, both of them may be here briefly described. The more abundant form presents the coloration which, according to Malmgren, distinguishes the Spitzbergen form from the Baltic one ; the inner margins of the elytra are broadly chestnut-brown ; the dorsal (and sometimes also the ventral) sm'face exhibits a light ground-colour, upon which there are light brownish band-like mark-ings ; sometimes the whole coloration is uniform ; in other cases the elytrophora were of a deeper brown colour. The largest animals of this form were of the size given also by Malmgren for the Spitzbergen form, viz. 35 millims. in length and 17 millims. in breadth, including the setge. The other race possesses a clearly marked coloration and pattern. The elytra are broadly bordered with greenish grey on the inner and hinder margins, and usually bear, at the * Sitzungsbericlite der phys.-medic. Societat zu Erlangen, June 7, 1871. Translated by W.
