The first specimens of Myotis velifer from California were taken in 1909 by C. L. Camp at Needles, San Bernardino County (Grinnell, Univ. California Publ.

Mamm., 20:226, May 14, 1939). West of the Rocky Mountains the... more...

When preparing distribution maps for a revised list of the Mammals of Kansas it became apparent to me that pocket mice of the species Perognathus flavescens from south-central Kansas and adjoining parts of Oklahoma were without a subspecific name. The new subspecies is named and described below. Perognathus flavescens cockrumi new subspecies Holotype.—Female, subadult (P4 moderately worn), skin with... more...

In September, 1958, the author and two colleagues collected a large series of Pseudemys in small ponds and in a river in the basin of Cuatro Ciénegas, Coahuila. The specimens prove to represent a previously unrecognized subspecies of Pseudemys scripta. The subspecies is named in honor of Edward Harrison Taylor who has contributed more than any other person to our present knowledge of the herpetofauna... more...

The fruit-eating bats of the genus Sturnira are represented on the North American mainland by two species, S. lilium and S. ludovici. The former, in most areas the smaller of the two, is widely distributed in México and Central America and is common in many places. On the other hand, S. ludovici, described by Anthony (1924:8) from near Gualea, Ecuador, generally has been regarded as rare; insofar as... more...

Field and museum studies of the wood rats of Colorado have revealed the existence of an unnamed subspecies of Neotoma mexicana in eastern Colorado south of the Arkansas River. The characters of the new subspecies are most distinctive in the northeastern part of its range near Two Buttes and Higbee. It differs in cranial characters from N. m. fallax and N. m. inopinata and averages slightly larger, but... more...

Heretofore our knowledge of the osteology of Heliscomys Cope has been extremely limited; this genus previously was known by its teeth, fragmental maxillaries, incomplete palatine bone and mandible, and part of one forelimb. In the summer of 1946 the writer, as a member of the University of Kansas Museum of Natural History field party, discovered the anterior part of a skull of Heliscomys in the middle... more...

The printed story of Niagara dates back only three centuries; and during the first three decades of even that period the references to this wonderful handiwork of Nature—which was located in a then unexplored region of a New World, a Continent then inhabited only by warring tribes of superstitious Savages—are few and far between. Three facts relating to this locality—and three only—seem to be... more...
