473 Canon A. M. Norman — Notes on the 



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



are :- 



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



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



MOLLUSCA (continued). 



The following additional species and varieties were recorded 

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



Theshia vayia, Loven. 

 Buccinum Donovani t, Gra}^ 



/}*a(/??«, Verkriizen. 



parvuhim, Verkriizen. 



Baccinum Uumphreysianum, Ben. 

 Sijoho Sarsii, Jeffr. 

 Helcion pellucidum, Linn. 

 Gibhida cineraria, Linn. 



Since the preceding part was sent to press I have received 

 from Herr Friele an account of the Mollusca dredged by the 

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

 from the Porsanger Fiord which are additions to the fauna of 

 East Finmaik : — 



Corypliella Sarsi, sp. n. j Ampidlina Smithii, Brown. 



Dendronotus robiistus, Verrill. Limopsis minuta, Phil. 



Acera bullata, 0. F. Miiller. ' 



The number of Mollusca of East Finmark, according to the 

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

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

 Lov^n, Schneider, and Frlele. 



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

 ' Mollusca regionis Arcticte Norvegise,' 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 that he classifies the whole of the species contained in 

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

 following fourteen : —

 Tromso Museums Aarsberetning, 1882, p. 81 ; and Thesbia nana, Lov6n, 

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

 fiorde. III. Tromsosundets Molluskfauna," Tronaso Museums Aarshefter, 

 viii. 1886, p. 22. 



t This and the two following Biiccina I regard as varieties of B, un- 

 datmn and B. groenlandicitm.
