Feb. 22, March 12, 17; Rio Sta. Maria, 2 specimens, Feb. 4; Wakena- 

 kili Mountains, i specimen, May 3 ; Las Canoas, i specimen, September. 



Two of the Estancia specimens are in the black phase; all the 

 others are in the gray phase. 



Also Los Masos, 4 specimens (i female, 3 males), all adult and 

 all in the gray phase. 



3 . Tatu novemcinctum mexicanum (Peters) . 

 Two specimens, Las Canoas, Aug. 12, 21. 



4. Tayassu angulatum sonoriense (M earns). 



Four adults collected as follows: La Cienega, c? ad. (skull only), 

 April 23; Wakenakili Mountains, 9 ad., April 26; Volcan de Fuego, 

 cT ad., July 16; Los Masos, i very old female. 



The collector's measurements of the first three of these specimens 

 are, respectively, total length, 901, 965, 934; head and body, 864, 

 914, 914; tail vertebrae, 37, 51, 20; hind foot, 190, 197, 190; ear, 89, 

 79, 95. Skulls, respectively, total length, 236, 238, 241 ; basal length, 

 178, 182, 189; palatal length, 130, 129, 134; width of rostrum, 29, 28, 

 30; zygomatic breadth, 95, 101, 107; postorbital processes, 69, 68, 

 75; width of braincase, 53, 54, 58, width of palate at m 2 , 19, 21, 22; 

 width of basioccipital, 17, 16.5, 21; upper molariform series, 61, 

 58.5, 63.5; audital bulla, 10.5 x *3> II X *3 I2 X 13-5- One of the 

 skulls has the orbitosphenoids and adjacent parts inflated; in the 

 other two they are normal (see ante a, p. 201). 



The Wakenakili Mountains specimen is strongly suffused with deep 

 buff, especially on the sides of the head, sides of the neck, the chest, 

 flanks, and shoulder stripes, which latter are unusually conspicuous. 

 The Volcan de Fuego specimen is much less suffused, and the shoulder 

 stripes are not prominent. This specimen, from the locality, should, 

 perhaps, be. referable to T. a. humerale, from Armeria, State of Colima, 

 but it is not apparently distinguishable from average Sinaloa speci- 

 mens (see ante a, p. 203). The three Jalisco skulls find exact counter- 

 parts in the Escuinapa series. 



5. Odocoileus sinaloae Allen. 



Eighty-two specimens: 14 skins with skulls, 8 additional skulls, 

 and about 60 pairs of antlers. The skins with skulls were collected 

 as follows: Estancia, i adult male, Jan. 24; La Cienega, i adult male,
