OBSERVATIONS ON PLATYGONUS COMPRESSUS 

 LECONTE. 



In the museum of the University of Michigan there is a 

 collection of bones of a fossil peccary, found in the peat-bog 

 near Belding, Ionia county, Mich. The late Professor Alexander 

 Winchell correctly identified the material as belonging to Platy- 

 go?ius compressus, first described by John L. Leconte (1848, 

 1848^). Professor Winchell published nothing on the subject, 

 and there is now no record of the exact relations the bones had 

 to each other when found.

According to Professor Winchell's labels, five specimens are 

 represented in the collection. One series, comprising a nearly 

 complete skeleton, was by him referred to one individual ; the 

 only reason for doubting this collocation is that the skull seems 

 to be of a male, while the sacrum agrees well with that referred 

 by Williston to a female (1894, p. 36). In all probability the 

 differences shown in the sacra figured by Williston arc merely 

 individual. The other bones of this series clearly belong 

 together, and the bones are in excellent preservation. The 

 other skeletons are represented by much less complete material.
