i adult female, April 16, 21; Wakenakili Mountains, i adult male, 

 May 6; La Laja, i young adult male and i old male, May 19, 25; 

 Volcan de Fuego, 3 males, 2 females, and additional skulls, July 828; 

 Volcan de Nieve, 2 adult males, Sept. 7, Oct. 2. The antlers were 

 collected mostly at La Cienega, La Laja, and the near-by Mesa de 

 Cullutan. 1 



Of the 10 males (skins with skulls), 4 are more or less imma- 

 ture, two of them being about half -grown and the others young adults; 

 of the 3 females, only one is an old adult, the other two being 

 more or less immature. The collector's measurements of the adults 

 are as follows: 



Adult males,- 6 specimens: Total length, 1422 (1373-1473); head 

 and body, 1225 (1194-1282); tail vertebrae, 196 (179-203); hind foot, 

 377 (368-406); ear from notch, 152 (133-165). One old female: 

 1359, 1156, 203, 356, 140. 



The subjoined table of measurements of skulls shows the same 

 wide range of individual variation in all the principal dimensions as 

 in the Sinaloa series (see antea, p. 207), with no average difference 

 of any importance. In the Sinaloa series of 6 males the nasals average 

 slightly larger than in the 5 males from Jalisco, but the nasals are 

 so inconstant in size and form that a few more specimens added to 

 either series might materially change the average. In all other 

 measurements there is no appreciable difference. 

 MEASUREMENTS 2 OF 7 SKULLS OF Odocoileus sinaloa FROM THE STATE 



OF JALISCO, MEXICO. 



1 Also 7 specimens (skins and skulls), and 4 additional sets of antlers, from Los Masos. Six of 

 the skins are very old females in the gray winter coat; the other is a young male in the red summer 

 coat. 



2 For explanation of measurements see antea, p. 207. . Condition of teeth: g. w. greatly 

 worn; m. w. = much worn; n. w. = not worn. s. w. = slightly worn.
