SSmecefl brevlroatrlBt f group 



I am Just about convinDed that thd relation- 

 ship that exlBts In this group Is almost enttrely 

 subspeclflc, except for the forms dlcel and 

 collmenels. The form IndubltuB le difficult to 

 separate from brevlrostrls at best, and Is perhaps 

 conspeclflc. To)5 be charitable, let us dall It 

 the southern end of the plateau subspecies. 

 The northwestenn portion of the brevlrostrls 

 group, perhaps characterised by the enclosure of 

 the paEt Interparietal by the parletals, and 

 pattern, is an unnamed subspecies of the form. 

 Additional material from Durango Is needed here, 

 to see actually what happens to the Interparietal 

 there, ■EhezBEtttabzMaseiaai Taylor had four specimen 

 from the apparent range of this subspecies, but 

 only one had the parletals united behind the interp 

 judging from the text on p. k$5. There is a 

 probable eateEB eastern plateau form, into Veracruz 

 and south to Oaxaca, which probably includes the 

 type form. This form and ochoterenaa will prob- 

 ably be found to intergrade in the Sierra Madre 

 del Sur between Guerrero and Oaxaca, if they can 

 be maintained as entities. The species dugesli 

 can probably be maintained as a full species, 

 also, on the basis of the three supraoculars. 

 This outline ps partly confirmed by the Eumeces 

 I collected in Jalisoo in the Nevado de Colima, 

 which would be intermediate tofi&Haea betvreen the 

 N¥ subspecies and indubitus-with one out of ^ 7 

 lacking complete enclosure of the Interp. by the 

 parletals. 



The group/, as I see it, is compased of the 

 following: 



Brevlrostrls brevlrostrls 



b. Indubltus 



b. ochoterenae 



b. subsp. 



dugesii 



collmensis (perhaps no good at all) 

 dlcel
