LAMELL1BRANCHIATA. ioi 



Iceland. 



A.Montagui has been taken in large quantity on the west coast, in part also on the east 

 coast; from the south coast there are but few specimens and from the north coast only one. but 

 whether this is due to imperfect collections or to the actual scarcity of the species on the north coast. 

 I am unable to say 1 ). The depths noted lie between ca. 8 — 50 fin. On the west coast it readies to 

 19 mm ., and on the east coast to a very considerable size, namely 26.2 ' 



The various localities are as follows. 



East Iceland: 



Myre Bugt 26 fm. 1 valve. 



Berufjordr, Djupivogr 6—9 - , mud with black sand. 50 spec. 



Mouth of Berufjordr 54— 41 - , ooze. 1 



64°58'N.L., i3°25'W.L 40 - 4 & 27 valves. 



Breiddalsvik 14 - 2 & 1 valve.

Vidfjordr 8-12 - 1

Seydisfjordr 15— 20 - 1 



, the mouth 38—14 - , mud. 12 



, off Brimnes 40 - , ooze and clay. 1 



The specimens from East Iceland belong in part to the variety striata, in part to the typical 

 form or to transitional stages between the two, as will be seen from the following- measurements:

1) As Odhner in Ins list over the comparatively small collection of marine Mollusca from Iceland in the Stockholm 

 Museum records the species from 2 localities from the north coast (Arkiv for Zoologi, Bd. 7, No. 4, [910 p th< firsl view 



seems to be the most probable one.
