the pad is distinctly larger than the tubercle. The width of the 
creeping pads is used by Bouvier as a diagnostic character for 
the separation of the two species but the form of these in the 
present specimens do not appear to indicate a clear relationship 
in either direction. Both females measure about 60 mm. in 
length in a fully expanded condition and have 28 pairs of legs, a 
typical number for either species.

Two large females from the Santa Marta Mountains, 
Colombia, June 6 and 22, 1920 (F. M. Gaige.) 
Both measure fully 60 mm. in length and have 31 pairs of 
legs. They agree well with Bouvier’s description of the single 
type from French Guiana in all details, except in color. The 
type was evidently completely decolored as the present specimens 
show distinct indications of a series of lozenge-shaped markings 
along each side of the median line and a very distinct interrupted 
dorsal transverse pale band behind the head almost exactly 
similar to the band of P. torquatus. Possibly this collar may 
indicate a color variety as it is described by Clark (1913) as 
present in a specimen from La Chorrera, Panama which 
examined and referred to this species. The head and antennae 
are extremely dark in the present examples and the band so 
much lighter than the body behind it that one would not expect 
it to disappear entirely even in specimens so completely decolored 
that the lozenge-shaped markings are practically faded out. 
Nevertheless, Bouvier makes no mention of such a band and 
speaks of the antennae as darker than the head, which suggests 
strongly that the western form may be distinguishable on this 
color character. On the other hand there is with one of the 
Colombian examples, a very poorly preserved specimen quite 
possibly of this species which shows no indication of any pale 
band; it appears also to be a female.
