The Baculum in the Chipmunks of Western North America

The baculum is the bony part of the penis. In the species of the subgenus Neotamias the proximal part of the baculum is termed the shaft, and the distal upturned part is termed the tip. On the dorsal side of the tip there is a longitudinal ridge termed the keel. The proximal end of the shaft is termed the base (see fig. 19). Depending on the species, the shaft varies from 2.11 to 5.28 mm. in length, and the base may or may not be widened or deepened. The purpose of this report is to: (1) Show the usefulness of the structure of the baculum as a taxonomic character in chipmunks;[Pg 614] and (2) compare a classification based on the structure of the baculum with a classification based on the structure and appearance of the skull and skin. The bacula which were borrowed from the University of Michigan, Museum of Zoology, were processed according to the method described by Friley (1947:395-397), whereas all others were processed according to the method described by White (1951:125). Thus the bacula that were borrowed from the University of Michigan, are maintained there in a separate collection, whereas the bacula borrowed from other museums and those that are at the University of Kansas, Museum of Natural History, are housed with the skulls of the corresponding specimens. ......Buy Now (To Read More)
