Myology of the Hind Limb of the Raccoon.

With Plates XIV, XV, and XVI. 
This paper was suggested on noting how much certain muscles 
in specimens of the Raccoon dissected by the author differed from 
the description by Dr. Harrison Allen. (The Muscles of the 
Limbs of the Raccoon, Procyon Jotor, by Harrison Allen, M. D., 
Proc. Acad. Nat. Sci. of Phila,, 1882, pp. 115-144.) These varia- 
tions are of special interest since they occur ina generalized species 
of low intelligence, whose individuals differ little in habits, and 
among which we should expect little variation in structure. Dr. 
Allen’s descriptions were based upon dissections of two female 
faccoons which had probably been in captivity. This may have 
Changed the proportions of certain muscles, but certainly not their 
attachments. My specimens differed little among themselves and ay 
Seemed to present a normal structure judging from other carnivor- 
ous animals; while in some cases Dr. Allen’s arrangement would 
be very remarkable. 
If errors exist in Dr. Allen’s work they may safely be attributed 
to oversight or lack of material. Errors are prone to occur where 
everything depends upon accurate dissection and observation, and 
although much care has been taken in the preparation of this paper 
me author cannot hope that all errors have been avoided. 
: Che material upon which this paper is based consists of an adult 
female raccoon and two very large males. These specimens were 
Procured through the kindness of Mr. J. C. Saunders of Lawrence. 
In most instances only such muscles are considered as seem to 
Present variation or other interesting features.
