50 NELson, WVew Birds from Mexico and Guatemala. van 
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 Jalisco 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. 154889, U. S. Nat. Museum, Dept. Agric. coll., ¢, 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. 
The type of sanctorum measures as follows: Wing 111, tail 64, culmen 25, 
tarsus 21. An average male from the region whence came the type of 
jardin 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 sardiniz 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 Vailey of Mexico and Mt. Orizaba, Puebla, are 
typical yardiniz, 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 bird, jardin. Ten 
specimens before me from Chiapas and Guatemala, are very dis- 
tinct from sardinii, being decidedly smaller and very much darker 
in color. Specimens in the National Museum from these two 
regions support the conclusions drawn from our collection.
