CO Nelson, Netv Birds from Mexico and Guatemala. I \^^ 



siderable series of these birds I find that specimens from the hot, 

 dry ' tierra caliente ' midway on the mountain slopes draining to 

 the Pacific, from Etzatlan in Jafisco to southern Puebla and adja- 

 cent parts of Oaxaca, agree in being smaller and duller colored 

 than those from the more humid districts near the coast, between 

 Mazatlan and Tonala. The bird of the interior being the typical 

 form, it remains to describe that of the coast region. 



// Dryobates sanctorum, new species. Chiapas Woodpecker. 



Type, No. 154S89, U. S. Nat. Museum, Dept. Agric. coll., J, Todos 

 Santos, Guatemala, December 30, 1895. Collected by E. W. Nelson and 

 E. A. Goldman (Orig. No. 3321). 



Distribution. — High mountains of Chiapas and Guatemala. 



Description. — The lower surface is an intense smoky brown, and the 

 outer tail-feathers have their light areas nearly as dark. The dorsal 

 stripe in most cases is like the ventral surface but is rather more fulvous. 

 Tlie type of sanctorum measures as follows: Wing iii, tail 64, culmen 25, 

 tarsus 21. An average male from the region whence came the type of 

 jardiiiii measures : Wing 127, tail 80, culmen 28, tarsus 21. 



In the collections made by us in Mexico and Guatemala are 

 two distinct Woodpeckers of the jardinii style. One series of 

 eight specimens from the mountains of central Mexico, taken at 

 localities ranging from the State of Michoacan to the mountainous 

 borders of the Valley of Mexico and Mt. Orizaba, Puebla, are 

 typical jardinii. South of this region, in the mountains of 

 Oaxaca, these birds become extremely rare. Crossing the Isth- 

 mus of Tehuantepec and entering the high mountains of interior 

 Chiapas and Guatemala, a smaller species is found which has 

 hitherto been referred to the central Mexican h'nd., jardinii. Ten 

 specimens before me from Chiapas and Guatemala, are very dis- 

 tinct irom jardinii., being decidedly smaller and very much darker 

 in color. Specimens in the National Museum from these two 

 regions support the conclusions drawn from our coljection.
