ARKIV FÖR ZOOLOGI. BAND 7. N:0 4. 



According to the above accounts the follovving species, 

 which are before mentioned from Iceland, must be removed 

 from the fauna: 

 Retusa obtusa (Montagu) mentioned by Jeffreys-, 



Lyonsia iiorvegica (Chemnitz) » » » 



The following species must be regarded as doubtful in- 

 gredients of the fauna: 



Chito7i cinereus Linné mentioned by Jeffreys; 



Lunatia Montagui (Forbes) » » » 



Venus lincta Pulteney » » » 



Thracia prceienuis Pulteney » » » 



Area glacialis (Gray) is included in the list of Iceland 

 moUusca by Mörch (1869) vvith the remark, that Torell 

 (1859) mentiones it from Iceland. Such a statement is hovv- 

 ever not met with in Torell; perhaps Mörch has wrongly 

 read Torell's notice of its occurrence at Melville-Island. 

 This species belongs however to the Iceland fauna according 

 to PossELT k Jensen (1899). 



III. General remarks on the fauna. 



Though the majority of species is obtained from Beru- 

 f jord and this loeality thus is the one best explored, the above 

 survey permits a comparison from which some faunistic re- 

 sults of interest are to be deduced.
