skins. Lutra californica (page 254) was named by Dr. Gray in 
1837, although redescribed by Prof. Baird in vol. viii, P. R.R, Rep., 
from a specimen from the Cascade Mountains. The subject ends 
with a description and measurements taken from a freshly-killed 
specimen from Beaver Creek, Arizona. 
A second paper in the same article describes the new subspecies 
Spilogale phenax arizone (Arizona Striped Skunk), of which 
thirteen specimens were examined from the vicinity of Fort Verde, 
Arizona. Dr. Merriam’s type of S. phenax came from Nicasio, 
Cal. The article ends with ‘‘A Study of the Arizona Skunks of 
the Genus Mephitis.” W. 8, 
Notes on New or Little-known North American Mammals, based 
on recent additions to the Collection of Mammals in the American 
Museum of Natural History. By J. A. ALLEN. Bull. Am. Mus. 
Nat. Hist., iii, 2, Art. xx, pp. 263-310. The present paper is 
based upon_a critical examination of several thousand skins, mostly 
with crania, of mammals received by the American Museum of 
Natural History during the last four years. The introductory 
briefly notices some changes in mammalogy since the publication in 
1857 of Prof. Baird’s great work on North Ammerican Mammals, 
when less than 3,000 specimens were available for study, a smaller 
amount than has been collected annually during the past few years. — 
The MS. name He/eromys alleni Coues is revived for a pouched 
rat ranging from southern Mexico northward to the mouth of the 
Rio Grande, and distinct from. H. dongicaudatus of Central America. 
An excellent study of the genera Dipodomys and Dipodops is 
given. Since 1886 the number of species of Dipotomys has in- 
creased from two to twelve and been divided into two genera with 
six species to each. To these Dr. Allen adds Dipodops ordii pal- 
mert subsp. nov. from San Luis Potosi, Mexico, and Dipodops 
vichardsoni sp. nov. from Indian Territory, and probably extending 
“over the Plains from northern Texas to southern Wyoming and 
westward to the Rocky Mountains.” Perognathus ( Chetodipus) 
femoralzs Allen is a new species from Dulzura, San Diego County, 
Cal. 
The long lost species Meotoma micropus Baird (Texan Wood Rat) | oe 
is revived upon the basis of eleven specimens from Brownsville, _ 
Texas, which, with those from other localities, made a series of ©
