average specimens of P. semispinosus, which, however, is white below as in 
P. centralis, and a very much smaller species with markedly different cranial 
characters. | 
Oryzomys incertus Allen (preoccupied). 
I am indebted to Mr. E. A. Goldman for kindly calling my attention to 
the preoccupation of the name Oryzomys incertus (this Bulletin, XXXII, 
p. 598, Dec. 3, 1918) by my previous Oryzomys alfarz incertus (this Bulletin, 
XXIV, p. 655, Oct. 13, 1908). My later O. incertus is here renamed Ory- 
zomys mureliz, after the type locality. 
Procyon (Euprocyon) equatorialis sp. nov. 
Type, No. 36458, o ad., western Ecuador, probably near the coast in Manavi 
Province, June, 1913; W.B. Richardson. (The collector’s label was lost in transit, 
but the specimen was taken on his route from Manavi to Mt. Pichincha, via Gualea. 
The hispid character of the pelage indicates that it was taken in the tropical coast 
belt.) 
Pelage very short and bristly. Similar in general coloration to specimens of 
Procyon cancrivorus nigripes from Corrientes, Argentina, but pelage very short, 
stiff and without underfur, the general tone much yellower, the black tipping of 
the hairs of the upperparts much shorter, the tail and feet with much less black. 
Frontal band on face broad and deep black, posteriorly enclosing the eyes; a whitish 
band above the eyes extending nearly to base of ears; top of head and nape gray 
strongly varied with black, the hairs being whitish at base with black tips; upper- 
parts yellowish, the hairs tipped with black, forming a blackish wash; underparts 
maize yellow; forearm and ankles black; feet pale buffy brown; tail below light 
maize yellow, paler above with indistinct blackish half-rings; ears externally like 
the nape, edged with yellowish white, internally yellowish white. 
Total length Gin skin), 1070 mm.; head and body, 755; tail vertebrae, 315; hind 
foot, 95. 
Skull, total length, 127; condylobasal length, 119; palatal length, 69; ZY Z0- 
matic breadth, 87; interorbital breadth, 26; postorbital breadth, 25 ; breadth of 
braincase, 54; mastoid breadth, 71; maxillary toothrow, 40.3. 
The skull is that of an old male, with a low sagittal and heavy occipital 
crests. Dentition intermediate between that of cancrivorus 1 and proteus — 
less massive than in the former and heavier than in the latter. 
In coloration the Ecuador form is quite distinct from any of the previ- 
ously described forms. : 
As already noted, the exact type locality is not known, but the short, 
hispid pelage seems to imply that it must be in the tropical coast region of 
Manavi.
