In view of far-flung geographical position of Mount Logan area, approaching’ farthest 
limit of distribution of species, it is assumed that all above specimens can be regarded as 
belonging to a single race. Here, if anywhere on the continent, we would expect to find 
cinnamomeus pure and unmixed with solitarius even at dates when farther south migrant 
intrusives might be expected amidst the resident population. The writer thinks he is 
justified in forming tentative presumption that all four specimens here listed belong to a 
single race. 
Principal distinctive characters of cinnamomeus are: (l) cinnamon instead of white 
spots on back; (2) marbled or freckled areas on inner webs of first primaries; (3) large 
size, best recognized in specimen by length of wing. 
Examining these specimens for these criteria it is found: No. 1, slight suggestion of 
marbling at base of first primary, a long wing (5-4 inches), and white back-spotting. 
No. 2, well-marbled primaries, very long wing (5-5 inches), and white back-spotting. 
Nos. 3 and 4: one has marbled primaries, other not. Wings short (3 — 5-1 inches; 4 — 5-07 
inches) and back-spotting decidedly buffy. 
Therefore, all referable on one ground or another to cinnamomeus, but none shows all 
postulated characters and evident that no one character consistently constant. Cinna- 
momeus may or may not have marbled primaries, may or may not have long wings, and 
may or may not have buffy back-spotting. From the study of a considerable series of other 
specimens writer convinced that buffy back-spotting is a character restricted to juvenile 
and in that plumage is the most constant distinction of cinnamomeus. He has not seen 
it exhibited in any striking degree by any eastern specimens and it is present in all juveniles 
that can be referred satisfactorily on other ground to cinnamomeus. Marbled primaries, 
when they occur, seem to be certain and reliable evidence of tinnainomevs, but not present 
in all of that race. Cinnamomeus usually of large size, but not always, and includes’soroe 
individuals that are as small as many pure solitarius. 
Evident that in this northwestern extension of continent and extending’east and 
southward for an unknown distance there exists a strain of solitary sandpipers that averages 
large, is inclined towards marbling on the primaries, and shows buffy back-spotting when 
juvenile. Probably majority of this strain distinctly characterized, but some or perhaps 
many indistinguishable from type form by any test known at present. By current stand- 
ards cinnamomeus a distinctly good race. 
Probable extent of breeding area of these birds uncertain. In migration through 
southern British Columbia Allan Brooks (A Distributional List of the Birds of British 
Columbia, Pacific Coast Avifauna No. 17, 1925, p. 43) refers 30 per cent of migrants to 
solitarius, but has no exact information as to breeding of either particular form in province. 
It may be that many of these supposed solitarius are the unrecognizable cinnamomeus above 
mentioned, or a more southern breeding stock. Along east side of Rocky mountains 
solitarius is only form identified actually breeding (Didsbury and Belvedere, Alberta), but 
cinnamomeus occurs at both places and elsewhere in same general region very early in 
migration season and even before many locally raised young are independent of parental 
care. (P. A. Taverner, Ornithologica Investigations near Belvedere, Alberta, 1926; 
Annual Report for 1926, National Museum of Canada, 1928.) Farthest east cinnamomeus 
definitely recorded by authority is at Maple Creek, Sask., June 30, by Dr. Bishop — - 
probably an early migrant. 
15. Bartramia longicauda (Bechstein) Bartram’s Sandpiper 
On August 9, while stalking sheep high on alpine slopes far above 
timber, one of these sandpipers met. No mistaking identity of bird 
as it was seen and heard at very close quarters. 
16. Actitis macularia (Linnaeus) Spotted Sandpiper 
First met May 16 near Bryson’s cabin where six were noted. Species 
evidently nested low; was not seen near foot of glacier until July 9 and 
a week later family groups in evidence. By end of month species quite 
numerous and had penetrated canyon stream beside moraine even beyond 
Trail End. Often observed a few yards back from edges of silty streams and 
several constant attendants at camp where they frequented spot on gravel 
in which refuse buried, having a busy, delightful time catching blow-flies. 
In stalking flies employed methods of young turkey or chicken, stealing
