| VITRINA PELLUCIDA. 
RUSSIA. 
Vitrina pellucida is said to be found in Northern and Southern Russia ; and is 
especially recorded for Moscow, Livonia, Courland, Poland, and the Cis- and Trans- 
Caucasian region; it is common throughout Finland, and extends to the extreme 
north of Lapland, whence V. angelice is reported by Moellendorff. 
NORTH AFRICA. 
Algeria—J. W. Flower (Jeffreys, Brit. Conch., 1869, v., p. 157). 
ARCTIC AND SIBERIAN SUB-REGIONS. 
Siberia—Recorded for Tomsk in the Obi Valley, Jenissei Valley, Irkutsk, the 
Baikal and Tranbaikalian region, the Valley of the Amur, and Kamtchatka. 
Turkestan— Recorded for near Yarkand by Nevill. 
Cashmere—Godwin-Austen, on the authority of Stoliezka, records it from 
Mataian, Dras, Lahul, and from the north of Zoji La, but thinks that as the animal 
of the European form is pale in colour, while the Cashmere form is ‘‘blackish with 
short tentacles,” that they may prove to be distinct species. 
N.E. Asia—V. pellucida exilis inhabits North-eastern Asia, reaching from 
Tschukschis peninsula in the north, as far as Japan in the south, overlapping on 
the east the area inhabited by V’. pellucida alaskana, and on the west mingling 
with the typical form. 
NEARCTIC REGION. 
Labrador—Vitrina angelic is recorded by Tryon for Labrador. 
Greenland—Dr. Westerlund records this species as V. angelicw for Godhayn, 
from which latter place Dr. Jeffreys recorded it as V. pellucida. 
Canada—V. pellucida limpida is recorded as inhabiting the provinces of 
Alberta, British Columbia, Keewatin, Manitoba, New Brunswick, Ontario, and 
Quebec in the British Possessions; and V. pellucida alaskana from British Columbia. 
United States. —V. pellucida limpida also exists in Maine, Massachusetts, 
Michigan, Pennsylvania, New York, and Vermont. 
V. pellucida alaskana is on the latest authority now considered to be restricted 
to the Pacific coast, from California to Alaska, including the Behring and 
Aleutian Islands, and to the States of Colorado, Idaho, Nebraska, Nevada, New 
Mexico, and Utah.
