Four females collected by Dr. Wm. M. Mann at Colum- 
biana Farm, Santa Clara, Costa Rica and a male sent later col- 
lected by Mr. P. Siggas at the same place. 
These specimens agree well with Bouvier’s description 
based upon five specimens obtained at three localities in Costa 
Rica. The females have 30, 30, 29 and 29 pairs of legs res- 
pectively and the male 27. All are of large size and well ex- 
panded, the females ranging from 65-73 mm. in length and the 
male is considerably smaller (48 mm.). The inner lamella of 
the mandible bears only one accessory tooth or may show the 
trace of a second very small one. In Bouvier’s material most of 
the specimens showed a well developed accessory tooth but 
there seems to be no constant difference. The creeping pads on 
all the legs are rather narrow and the fourth is very small. On 
the fourth and fifth pairs of legs the fourth pad is always very 
much reduced and pushed to one side by the nephri dial tubercle. 
Sometimes it is band-shaped, again rounded and no larger than 
the tubercle, and again has practically disappeared. 
Peripatus (Epiperipatus) biolleyi Bouvier, var.betheli 
Cockerell. 
Proc. Biol. Soc. Washington, vol. 26, p. 87 (1913. 
This species was described from a single female from the 
Atlantic seaboard of Guatemala at Puerto Barrios. Five spe- 
cimens were obtained by Dr. Wm. M. Mann at San Juan Pueblo, 
Honduras and have been sent for study from the U. S. National 
Museum. 
There are three females, each with 30 pairs of legs; they 
are in various stages of contraction and measure from 38-55 
mm. in length. Two males are much smaller, 22-25 mm. and 
bear each 25 pairs of legs. All are considerably bleached by the 
alcohol in which they are preserved and in none are there any 
traces of a color pattern. The darkest specimen is distinctly 
brown and thus similar to the “dark wood brown” of the type 
as described by Cockerell. In the arrangement of the inte- 
gumentary papillae, nephridial tubercles, creeping pads and 
mandibular teeth all agree closely with Cockerell’s description, 
except that in two specimens there are only eight minute teeth 
on the inner blade of the mandible.
