These specimens extend the range of quindianus in the Central Andes consider- 
ably to the north of previous records. 
Pages 236-240. ‘The receipt of 6 specimens of Mesosciurus hoffmanni quindianus 
from the immediate vicinity of Medellin, and of no specimens of the Mesosciurus 
gerrardi group from the Medellin region, renders it quite certain that the type locality 
of Sciturus gerrardi Gray, from ‘‘ New Grenada,’’ was not the vicinity of Medellin as 
assumed by me as probable on p. 236 of this paper. Furthermore, the present 
Antioquia collection contains 12 specimens of the gerrardi group from the immediate 
vicinity of Puerto Valdivia, on the lower Rio Cauca, which are not the form described 
and figured by Gray as S. gerrardi. On the other hand (see below), the series of the 
gerrardi group collected on the upper Rio Sucio (Pacific slope), at and near Dabeiba, 
is referable to my M. gerrardi salaquensis, which has no black tail-tip, and the limbs, 
shoulders and sides of the body are not red as represented in the description and 
colored figure of gerrardi, which represent a form more closely resembling M. gerrardi 
zulie (Osgood) than any other member of the group at present known tome. I now 
believe that the type locality of gerrardi is somewhere between the ranges of the 
zulie-cucute group of this paper and the form described below as baudensis, in north- 
ern Colombia, and that it is a direct connectant between them. A single specimen 
from Rio San Jorge (No. 32701), with the tip of the tail lost, but which apparently 
must have been black, conforms in nearly all particulars, even to a nearly white 
belly, with the requirements of true gerrardi, and also geographically with the type 
region now suggested. 3 
The specimens referred above (p. 239) to gerrardi I now find represent two quite 
distinct forms of the gerrardi group, both quite different from true gerrardi, as follows: 
Mesosciurus gerrardi baudensis subsp. nov. 
Mesosciurus gerrardi gerrardt ALLEN, antea, p. 236, part. 
Type, No. 33180, # ad., Baudo (alt. 3500 ft.), coast region of western Colombia, 
July 16, 1912; Mrs. E. L. Kerr. 
Back, from the shoulders to the base of the tail, with a broad area of intense 
glossy black, which extends also over the basal third of the upper surface of the tail; 
rest of the tail above deep red, without a black tip; fore limbs, shoulders and sides 
of the body deep red, which color extends along the lower edge of the flanks to the 
front of the thighs and hind limbs; the intermediate region between the black dorsal 
area and the red of the lower border of the flanks is grizzled ochraceous and black; 
whole ventral surface dark red; lower surface of tail black for the basal third, grizzled 
more or less with orange, the rest dark red, the hairs broadly banded mesially with 
black, the black usually showing more or less at the surface. 
Represented by two specimens from Baudo, 1 from Bagado, 1 from Juntas de 
Taman& (the latter not typical). 
Intergrades with M. g. choco to the northward along the coast, with salaquensis 
in the interior, and with millert to the southward. :
