Natural History of East Finmarlc, 473 



important mistakes, which I cannot tell how I came to make, 

 are : — 



Page 344, line 12, /or " Bombyces " read " Bombidae." 



Page 354, line 24, for " north-eastern " read " north-western." 



MOLLUSC A (continued). 



The following additional species and varieties were recorded 

 in 1882 from Vardo and Kirkenes by J. Sparre Sclmeider * : — 



Theshia nana, Loven. 

 Baccinum Donovani f, Gray. 



/rayi'Ze, Verkriizen. 



2X(rvulum, Verkriizen. 



Baccinum IIumj)7ire>jsianian, Ben. 

 SijiJio Sarsii, Jeffr. 

 Helcion pellucidum, Linn. 

 Gihhula cineraria, Linn. 



Since the preceding part was sent to press I have received 

 from Herr Friele an account of the MoUusca dredged by the 

 ' Michael Sars ' in 1900 |. Among these are five species 

 from the Porsanger Fiord which are additions to the fauna of 

 East Finmark :— 



Coryphella Sarsi, sp. n. 

 Dendronotus rohustas, Verrill. 

 Accra bidlata, 0. E. Miiller. 



AmpulUaa Smiihii, Brown. 

 Limojysis minvAa, Phil. 



The number of Mollusca of East Finmark, according k) the 

 foregoing lists, is 232 ; of these, 164 were found in 1890 by 

 myself, and 68 are added on the authority of G. 0. Sars, 

 Loven, Schneider, and Friele. 



Professor G. O. Sars, in the concluding pages of his 

 ' Mollusca regionis Arctica? Norvegije,' 1878, divides the 

 Norwegian Mollusca under the two headings of Arctic and 

 Boreal species. Although I should myself refer a few of 

 the species which he characterizes as arctic rather to a boreal 

 origin (as he himself would perhaps do with our present 

 knowledge of distribution), it may nevertheless be interesting 

 to state tliat he classifies the whole of the species contained in 

 the preceding lists as of arctic origin, with the exception of the 

 following fourteen : —

 Troniso Museums Aarsberetniug, 1882, p. 81 ; and Thesbia nana, Lov^n, 

 from Kirkenes, Schneider, " Undersogelaer af dyrelivet i de arktiske 

 Ijorde. III. Tromsosundets Molluskfauna," Tromso Museums Aarshefter, 

 viii. 1886, p. 22. 



t This and the two following Buccina I regard as varieties of B. un- 

 datum and B. groenlandicum.
