Type locality El Guayabal, 10 miles north of San José de Cucuta, 
Colombia, near the Venezuelan boundary. 3 
Geographic distribution. Known only from the vicinity of San José 
de Cucuta, Colombia. 
Description.— Similar to M. gerrardi zulie but much paler, the black of 
the upperparts duller and less glossy, the red of the underparts orange instead 
of orange red, the black on base of tail above and at tip more restricted and 
less intense. 
“Type (collector’s measurements), total length, 433 mm.; head and 
body, 215; tail vertebree, 218; hind foot, 57. Skull, total length, 54; zygo- 
matic breadth, 31.2; interorbital breadth, 17.4; breadth of braincase, 23.5; 
length of nasals, 16.5; maxillary toothrow, 9.” — Allen, /. c.

Remarks.— “A single specimen from Rio San Jorge (alt. 1000 ft.), 
closely resembles zulie in general coloration, including the orange red feet 
so distinctive of zulie@, cucute and true gerrardi. The proximal fourth of the 
upper surface of the tail is black, but the black at the tip of the tail is very 
restricted, consisting of only the terminal hairs. The bright red of the 
shoulders extends to the mid-dorsal line, as happens sometimes in both true 
gerrardi and gulie. It is probable that this specimen represents a geographi- 
cal form occurring in northern and northwestern Colombia connecting 
gerrardi directly with zulie. Further material is necessary to determine 
the point, no other specimens from this large area being at present avail- 
able.’’? — Allen, l. c¢.
