Marmot a caligata okanagana (King) (Okanagan Hoary Marmot). Type locality. Gold 

 Range, British Columbia. Distribution, Gold and Selkirk Ranges, British Columbia, and probably 

 main range of the Rocky Mountains in Alberta from Banff to Henry House ; exact limits unknown. 

 Specimens identified from Field ; Glacier ; Spillimacheen River ; Toad Mountain, south of 

 Nelson. 



Marmota caligata cascadcnsis Howell (Cascade Hoary Marmot). Type locality, Mount 

 Rainier, Washington ; altitude, 6.000 feet. Distribution, Cascade Range at and above timber- 

 line from Mount Rainier, Washington, north to Southern British Columbia. Specimens identified 

 from mountains near Chilliwack ; Hope; Howe Sound; Mount Baker Range near United States 

 Boundary ; Skagit River ; Spences Bridge ; Tammi Hy Mountain. 



Marmota Vancouver cnsis Swarth (Vancouver Island Marmot). Type locality, Mount Douglas, 

 near Alberni, Vancouver Island, British Columbia ; altitude, 4,200 feet. Distribution. Vancouver 

 Island, British Columbia. Known at present only from the mountains at the head of China 

 Creek, some 20 miles south-east of Alberni, in the Golden Eagle Basin and King Solomon Basin 

 and the surrounding slopes and ridges. 



Howell writes in his remarks of this species : " This peculiar marmot, although clearly 

 related to the Mainland species (Caligata), has, through isolation, developed striking characters, 

 both external and cranial. The tendency of isolated coastal forms in this group to become brown 

 (shown in a lesser degree by M. caligata vigilis and M. olympus) has reached the greatest 

 extreme in this species, the black colours of the Mainland forms being entirely lacking and 

 the white reduced to scattering hairs. After a season's exploration of the southern part of 

 Vancouver Island, Swarth came to the conclusion that the species is probably confined to a small 

 area in the vicinity of Mount Douglas." Specimens identified from Golden Eagle Basin ; King 

 Solomon Basin ; Mount Douglas. 



Addenda. 



Omitted in the list of Microtus occurring within the Province published in our Annual 

 Report of last year (1919) is :— 



Microtus richardsoni arvicoloides (Rhoads) (Cascade Water-vole). Type locality, Lake 

 Keechelus, near Snoqualmie Pass, Kittilas County, Washington ; altitude, 8,000 feet. Geographic 

 distribution, Boreal Zone of Cascade Mountains in Washington, Oregon, and Southern British 

 Columbia. Museum specimens from Mount Baker Range. 



This subspecies, the largest of our voles, appears to be hardly separable from Microtus r. 

 macropus of the Boreal Zone of the Rocky Mountains. According to Vernon Bailey in his revision 

 of the genus, a single specimen examined from Glacier, British Columbia, was fairly intermediate 

 between Microtus richardsoni (De Kay) and these two southern subspecies. 



ORNITHOLOGY. 



As no field collecting was done by any one of the Department this year, very little 

 ornithological material was secured; however, three species of birds of special interest can 

 be recorded here : — 



Sabine's Gull (Xema sauini) (Fork-tailed Gull). Although this bird had been on our list 

 of British Columbia birds for a great many years, the specimen secured at the request of the 

 Director hy Mr. J. G. French, of Glacier Point, Sooke, B.C., on October 11th, 1920. was the first 

 specimen to be received by the Provincial Museum. The range of this bird is Arctic Seas to 

 Southern America. It breeds on the coast of Alaska from Kuskokwym River to Norton Sound, 

 and in the Northern Mackenzie, Northern Keewatin, and Northern Greenland, and on the Arctic 

 Islands of Europe and Asia; in migration on both coasts of America and casual in the Interior. 

 Winters in Peru. Shortly after Mr. French had secured this specimen the Director and his 

 assistant saw several in the vicinity of Victoria Harbour.
