BANGS: BIRDS AND MAMMALS FROM HONDURAS. 159 
parts redder; skull similar, except audital bullae wider and flatter and basi- 
occipital longer and narrower. 
Color. — Upper parts, dark rich brown, between mummy brown and burnt 
umber, rather redder on rump, the head, back, and rump darkened and varied 
by a copious sprinkling of brownish black tipped hairs; under parts strong, 
buffy ochraceous ; feet and hands dark brown, the hairs colored about like those 
of the back ; ears blackish, nearly naked externally, sparsely haired inside, the 
color of these hairs about like those of the back ; tail black, nearly unicolor, 
being only just perceptibly paler below. 
The specimen is in long, fresh, unworn pelage, and there are a few pure white 
hairs scattered at irregular intervals along the back and sides. 
Measurements. — Adult ¢, type, total length, 265 ; tail vert., 105 (the tip 
of the tail is gone, probably 5 to 10 mm.) ; hind foot, with claw, 32; ear, 
from notch, 18. Skull, basal length, 31.4; occipitonasal length, 35.8 ; 
zygomatic width, 20.4; mastoid width, 15.2; interorbital width, 5 ; length of 
nasals, 12.6; length of palate to palatal notch, 16.2; length of upper molar 
series, 6.; length of single half of mandible, 20. 
Remarks. — Mr. Vernon Bailey kindly compared the two forms of Sigmodon 
contained in the present collection for me, with the Mexican series in the col- 
lection of the Biological Survey, and we agree that the one from the coast is 
a new form most closely related to S. hespidus saturatus; and that the form 
from farther inland is not separable from S. hispidus borucae, which thus has a 
wide range for a member of this group. 
Oryzomys couesi (ALsTon). 
Thirty-six specimens ; Yaruca, 1,000 feet. 
Oryzomys rhabdops Merriam. 
Nineteen specimens ; Yaruca. Among the skulls of this series there is a 
tendency to a peculiar swelling between the orbits; several specimens, how- 
ever, do not show this at all, and apart from this tendency the specimens from 
Honduras are exactly like the type series from Calel, Guatemala. 
Heteromys griseus Merriam. 
Two specimens, ¢ & 9; Yaruca. Dr. Merriam has compared these with 
his extensive Mexican material, and they prove to be identical with H. griseus 
from the mountains near Touala, Chiapas, Mexico. 
Dasyprocta punctata Gray. 
Two adult females; Yaruca.
