absent. The third upper incisor lacks the internal division com- 

 monly developing a short, independent cusp in Procyon. The length 

 of the palate behind the posterior molars is less than one-fourth the 

 total length of the palate, while in Procyon the reverse is true. Ex- 

 ternally Euprocyon differs from Procyon in the reversed direction of 

 the pelage on the neck; 1 from the hair-whorl on the median line 

 between the shoulders the pelage is inclined forward, meeting the 

 opposing pelage of the head along a V-shaped line between the ears, 

 the apex of the V directed backward; on the under side of the neck 

 the arrangement is similar, but the apex of the V points forward. 

 In addition the claws, especially of the hind feet, are straighter, 

 broader, more bluntly pointed, instead of being laterally compressed, 

 strongly curved and sharply pointed as in Procyon. The general 

 non-sectorial character of the dentition, the form of the upper car- 

 nassial, and the posterior shortening of the palate in Euprocyon sug- 

 gest gradation toward the ancestral Miocene genus Phlaocyon. 



Euprocyon differs from Procyon in its blunt claws, indicating a 

 non-arboreal habit, and its short powerful molariform cusps, adapted 

 for crushing hard substances, seems to fit it for a life, where crabs, 

 fish and mollusks are common foods. 



In Panama this raccoon inhabits the lowlands along the Caribbean 

 coast from the northern end of the Canal Zone easterly toward Col- 

 ombia. Mr. P. L. Sclater 2 recorded specimens from Colon in 1875. 

 One of the specimens obtained by me was killed as it emerged from 

 some tall papyrus grass near the edge of a swamp whence it had been 

 driven by a pack of hounds. Others were shot at night along the 

 banks of the Chagres River, where they were located. The stomachs 

 examined contained fragments of fish and crabs. 



Specimens examined. — Total number, 5, from the following locali- 

 ties: 



Canal Zone: Gatun (type locality), 3. 

 Panama: Cana, 1 ; Porto Bello, 1. 



ALOUATTA PALLIATA INCONSONANS, new subspecies 



Type from Cerro Azul (altitude 2,500 feet), near the headwaters 

 of the Chagres River, Panama. No. 1 71068, male adult, U. S. 

 National Museum (Biological Survey Collection), collected by E. A. 

 Goldman, March 23, 191 1. Original number 20995.
