a large white ear spot ; tail above blotched very irregularly with black 

 on a dingy white ground, the black massed so as to form transverse 

 bands of varying width on the apical third. 



Total length (as measured by the collector), 927 mm.; head and 

 body, 571; tail, 356; hind foot, 138. Skull, total length, 117; basal 

 length, 1 08; basilar length (of Hensel), 101; zygomatic breadth, 76; 

 breadth of rostrum at base of canines, 24; mastoid breadth, 50; width 

 of braincase, 47; interorbital breadth, 21.5; postorbital breadth, 28; 

 tip to tip of postorbital processes, 47; palatal length, 44; inner base 

 of incisors to end of pterygoid process, 66; width of palate at front 

 edge of p3, 25; audital bullae, 26 x 16.5; length of p3 on outer border, 

 14; width of ps at front border, 8. 



This is a very small form of the F. pardalis group, charac- 

 terized by pallid coloration, small size, and large, evenly con- 

 vex, greatly inflated bullae. A second specimen, about half 

 grown and still retaining part of the milk dentition, is similar 

 in markings and all other particulars except that the colora- 

 tion is a little brighter. 



Procyon proteus, sp. nov. 



Type, No. 23492, S ad., Bonda, Santa Marta district, Colombia; 

 coll. H. H. Smith. 



Coloration very variable. Type: Median dorsal region, from nape 

 to tail, blackish varied with yellowish, the hairs being broadly tipped 

 with black and subapically broadly ringed with fulvous; flanks 

 golden ochraceous; ventral surface ochraceous yellow; head blackish 

 varied with fulvous gray; a broad black band across the rostrum 

 extends back to the eyes, and passing backward encloses the eyes, 

 covers a broad space beneath them, and continues posteriorly to the 

 front base of the ears, where it sends a broad arm upward to join the 

 black area of the forehead; a broad yellowish white superciliary band, 

 and a small oval light median spot behind the eyes; muzzle, upper lip 

 and chin pale yellowish white; basal two thirds of ears externally 

 dusky, the apical third and inner surface dull yellowish, heavily haired ; 

 legs dusky on the outer surface and yellowish brown on the inner; 

 upper surface of feet pale brown, near "broccoli brown"; tail yellow- 

 ish brown, strongest basally and paler apically, with above about 

 seven black rings, and a black tip, the basal rings incomplete below. 



A second male specimen is paler throughout but otherwise similar. 

 Four females are similar in color pattern, but the dorsal area is much 

 blacker and suffused with gray instead of fulvous, with the light 

 facial markings white, and the flanks and ventral surface much 

 paler, the flanks being pale fulvous instead of orange, and the ventral
