4 Miller — Descriptions of Two New Raccoons. 



scarcely widened posteriorly and showing no tendency toward the broadly 

 rounded form of the terminal region characteristic of P. pygmseus. 

 General form of skull decidedly wider than in P. hernandezii, a peculiarity 

 equally noticeable in the relatively greater zygomatic breadth and in the 

 more inflated anterior portion of braincase. 



Teeth. — Though showing no special peculiarities of form the teeth are 

 readily distinguishable from those of Procyon hernandezii by their much 

 smaller size, and from those P. pygmseus by their less reduced condition, 

 this character especially noticeable in pm 4 . 



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

 body, 430 ; tail, 235 ; hind foot, 97 (93). Skull of type and of a second 

 specimen of the same age, the measurements of the latter in parenthesis: 

 condylobasal length, 101 (96.6); zygomatic breadth, 63.6(67.0); inter- 

 orbital constriction, 20.4 ( L9.0); breadth of braincase, 46.6 (4.">.0); nasal 

 (median), 25.2 (27.6); mandible, 7.i (72.4). For dental measurements 

 see table. 



Measurements of the skulls of P. pygmseus, the type, a young male with 

 sutures on upper part of braincase open (basal suture closed), and a 

 female of same age as type of pumilus: condylobasal length, 02.8 (91.8); 

 zygomatic breadth, 58.6 (HO. 2); interorbital constriction, 19.6 (19.8); 

 breadth of braincase, 43.0 (4:1.2); nasal (median), 23.2 (22.2) ; mandible, 

 69.2 (00.8). 



Measurements of a skull of P. hernandezii from Colima, Mexico, same 

 age as type of P. pumilus : condylobasal length, 115.4; zygomatic breadth, 

 70.2; interorbital constriction, 24.2; breadth of braincase, 50.4; nasal 

 (median), Ml. 2 ; mandible, 84.4. 



Specimens examined. — The type, from Panama, and a skull collected 

 by Lieutenant Couch and labeled Matamoras (No. 1388). 



Remarks. — In all essential features the Couch specimen agrees so closely 

 with the skull of the type that there can be scarcely any question as to 

 their identity, at least as compared with the large Procyon hernandezii 

 and the small-toothed P. pygmseus. It may, perhaps, be reasonably 

 doubted whether this individual was actually killed at Matamoras, but its 

 presence in Couch's collection appears to be a clear indication that the 

 species ranges far to the north of Panama. 



Procyon minor sp. nov. 



Type. — Young male, (permanent dentition in place but basal suture 

 open), skin and skull No. fllsf U. S. National Museum. Collected at 

 Ponite-a-Pitre, Guadeloupe, Lesser Antilles, by L. Guesde. Received from 

 the l'Herminier museum. 



Diagnosis. — Size and general appearance as in the other small members 

 of the genus (P. maynardi, P. pygmzeus, P. pumilus); skull with posterior 

 extension of palate so widened that its least breadth is decidedly greater 

 than distance from last molar to anterior border of mesopterygoid fossa. 



Color. — The skin is not in good condition, having apparently been 

 subjected to the action of some kind of preservative fluid. The color
