brownish purple with the papillae much lighter, due probably 
to the decolorizing effect of the alcohol used for preservation. 
The distribution of P. juliformis and P. dominicce and their 
varieties overlap in this region as the former extends eastward 
from Jamaica through St. Croix to St. Thomas while the latter 
extends westward from Dominica through Antigua to Porto 
Rico and to Haiti. So far as I know this is the first specimen of 
Peripatus to be taken on St. Croix. 
Peripatus (Epiperipatus) brasiliensis Bouvier. 
C. R. Acad. Sci. Paris, vol. 129, p. 1031 (1899) 
Bouvier, Monog. Onycophores, Ann. Sci. Nat. (9), vol. 2, p. 
269 (1905) 
The types and nearly all of the material of this species seen 
by Bouvier were from Santarem in the lower Amazon area of 
Brazil, but he referred a single specimen from Panama to this 
species with some doubt. Since then the species has been re- 
ported from Merida in the interior of western Venezuela. 
Recently a number of specimens have come into my hands 
as the result of collecting by several naturalists at and near the 
Barro Colorado laboratory in the Canal Zone. A prolonged and 
careful examination of these has led me to the conclusion that 
they may be more or less clearly distinguished from the Ama- 
zonian representatives of P. brasiliensis. Unfortunately no 
examples of the latter are available for comparison, and it has 
been necessary to rely upon Bouvier’s extended description of 
the latter for comparison. As will be shown later, the Pana- 
manian form seems to approach P. imthurmi in some respects 
although it could not possibly be referred to this common Col- 
ombian species. Certainly it cannot be regarded as a distinct 
species, but as it seems to represent a well marked geographical 
race common in a district far removed from the type locality of 
P. brasiliensis it may be best known by a distinctive name. 
Peripatus (Epiperipatus) brasiliensis Bouvier, var vagans, 
var. nov. 
$ . Length when well extended 65 mm. and probably con- 
siderably more to judge from one large contracted specimen.
