a very dark, beaded dorsal stripe the enlargements of which 
correspond to the body segments. Just lateral to the stripe 
is a narrow pale border which serves to render it quite 
conspicuous, especially in some specimens. The nephridial 
tubercles are practically of the same conformation in all of 
the forms. They are attached slightly or free from the third 
band which is emarginate and the fourth band is bent, but 
scarcely emarginate next to the tubercle.

1. Some of the primary papillae on the integumentary folds 
clearly much larger than the remainder and arranged 
in such a way that one or several smaller ones are reg- 
ularly interpolated between two large ones 2. 
Primary papillae variable in size but not showing a defi- 
nite arrangement on the folds with regard to size, i. e., 
the largest papillae are not regularly spaced with refer- 
ence to intervening smaller ones; very few or almost 
no accessory papillae 4. 
2. A number of accessory papillae present along the sides 
of the body folds 3. 
Accessory papillae very few in number, almost absent; 
30-33 pairs of legs in the female; blade of mandible 
with 14 teeth Peripatns dominie se Pollard, var. 
lachanxensis, var. nov. 
3. A bright orange spot at each side of the head (sometimes 
white in specimens that have been bleached by pres- 
ervation in alcohol) ; mandible with 11-12 teeth; 30-31 
pairs of legs in the female Peripatns manni Brues. 
No pale markings of this kind present; body uniformly 
dark above, except for the shaded, dorsal pattern; 
blade of mandible with 8-10 teeth ; 30-32 pairs of legs 
in the female Peripatns dominicx Pollard, var. 
haitiensis Brues. 
4. 28 pairs of legs in the female; mandible with 11 teeth 
Peripatns dominicse Pollard, var. basilensis, var. nov. 
33-34 pairs of legs in the female ; mandible with 9 teeth.
