Millet — Descriptions of Two Nev. Raccoons. 5 



indicates no special peculiarities; back rather uniformly clouded with 

 black, the light element of the grizzle bully white with an evident 

 yellowish tinge <»n neck; face markings normal, the light area above eye 

 well developed; whitisb terminal area on ear large ami conspicuous ; tail 

 not noticeably more yellowish than back, the black rings narrow but well 

 denned; underparts dark wood brown thinly overlaid by the whitish 

 longer hairs; interramial dark area narrow and ill defined. 



Skull. — The skull is too young to furnish a satisfactory basis for 

 comparison. It differs conspicuously, however, from that of other 

 members of the genus in the unusual breadth of the posterior extension 

 of the palate. The least width of this is 16.4 mm., the distance in median 

 line from level of posterior edge of last molar to anterior border of 

 mesopterygoid fossa (disregarding median spine or notch) is 12 mm. In 

 a specimen of /'. hernandezii <<i exactly the same age these measurements 

 are respectively 15.2 and 13.8. The same narrow form is also shown by 

 a young P. pygmseus. Audital bulla? with meatal portion not evidently 

 tubular. Mandible excessively slender, its depth at front of pm 4 con- 

 tained nearly 10 times in length to extremity of angular process, while in 

 the P. hernandezii of same age it is contained only about 7} 2 times in the 

 same length. 



Teetli. — In general the teeth resemble those of Procyon maynardi, thesmall 

 premolars showing the same tendency to be widely placed as compared 

 with the more crowded condition in other members of the group. The 

 cusps of all the teeth tend to be higher and narrower than in P. maynardi, 

 and the cingula of the three large upper cheek teeth are better developed. 



Measurements. — External measurements of type (from skin): head and 

 body, 440; tail, 185; hind foot, 85 (SI). Skull: condylobasal length, 

 !>4.(i; zygomatic breadth, 55.4; interorbital constriction, 17.8; breadth of 

 braincase, 44.8; nasal (median), 27.2; mandible, 70.4. For dental 

 measurements see table. 



Specimen examined. — The type. 



Remarks.— Although represented by a single rather unsatisfactory 

 specimen this animal shows such marked characters that 1 have no 

 hesitation in regarding it as a distinct species.
