Unless otherwise specified, lengths of antlers were measured along the curve._] ============================================================== MEASUREMENTS OF TESTES Seasonal change in the size of testes in adult males is indicated by the following data: June 3, 30×18 mm.; June 18, 51×28.5; August 17, 50×35; September 29, 61×38; October 16, 60×40. Two male fawns: August 20, 18×7; September 7, 15×8.5. _References on measurements._--J. C. Ross, in John Ross, 1835b: xviii; J. A. Allen, 1910: 8; Seton, 1929, +3+: 97; Sutton and Hamilton, 1932: 87; Flerov, 1934: 240; Murie, 1935: 75; Soper, 1944: 248; Banfield, 1951a: 30. _References on weight._--Parry, 1824: 305; Richardson, 1829: 241, and 1852: 290; Armstrong, 1857: 475, 498; Baird, 1857: 635; M’Clintock, 1860?: 184; Osborn, 1865: 227; Schwatka, 1885: 84-85; Collinson, 1889: 153; J. B. Tyrrell, 1892: 128; Whitney, 1896: 237; J. W. Tyrrell, 1908 (1898): 79; Jones, 1899: 329; Hornaday, 1904: 138, and 1914, +2+: 104; J. A. Allen, 1910: 8; Seton, 1929, +3+: 97-98; Critchell-Bullock, 1930: 55; Hornby, 1934: 105; Banfield, 1951a: 15, 30. _Geographical variation_ The comparatively few specimens available indicate that different populations on the mainland, between Hudson Bay and the Mackenzie River, vary in size. Final judgment on the significance of this variation must await the accumulation of more and better material. The lack of topotypical material from the Fort Enterprise area, Mackenzie, is a particular handicap. The extreme and average body measurements of five adult males from the Windy River area (see accompanying table) may be compared with those of three adult males, taken by R. M. Anderson, 1910 and 1912, at Langton and Darnley Bays (Nos. 34431, 34432, and 34435, Am. Mus. Nat. Hist.): length, 1980-2095 (2052); tail (two specimens), 152-165 (158.5); height at shoulder, 1066-1167 (1117); shoulder to hip (one specimen), 964. The average length of these specimens exceeds that of the Windy River specimens by 278 mm.; the average height at the shoulder, by 37 mm. The length of an adult male from Artillery Lake (J. A. Allen, 1910: 8) exceeds the Windy River average by 156 mm., and its shoulder height (Seton, 1929, +3+: 97), by 10 mm., but the length of its hind foot, as recorded, is 17 mm. less than the Windy River average.
