Sceloporus clarkii boulengeri Stejneger
Sceloporus boulengeri Stejneger, N, Amer. Fauna, 7:180, pi. 1, figs. 5a-c, 1893
(type locality, Presidio, about 50 miles [south] from Mazatlan, Sinaloa).
Sceloporus clarkii boulengeri: Burt, Trans. Amer. Micr. Soc, 54:171-72,
April, 1935 (part).
Remarks.—Sceloporus clarkii boulengeri has been recognized by
most authors despite some confusion with other lizards (Burt,
1935:172; Taylor, 1938:520) and some disagreement about the
taxonomic value of certain characters (Bogert and Oliver, 1945:
347). Intergradation between boulengeri and clarkii occurs near
Alamos (Bogert and Oliver, 1945:348) and Navojoa (Langebartel
and Smith, 1954:130), Sonora.
Little sexual dimorphism is evident in the following characters
of 140 specimens: snout-vent length, 33-126 (83.2); dorsal scales
28-37 (32.7) (excluding KU 29586, 37631, 63683); femoral pores
(total), 13-27 (18.6) (excluding KU 29586, 77823, 80728). There
are two rows of lorilabials below the suboculars in 126, one row in
six, one right and two left in three, and two right and one left in
