of the extremely long and tennons legs of the typical 
Gymnodamseus the legs are scarcely longer than body, 
and not especially slender ; the ventral apertures are well 
separated ; there is a strong tectopedum behind first and 
second trochanters.

One from Duke Forest, Durham, N. Car., 25 Nov. 
(Pearse). It was described mostly in comparison with 
a European species, Gymnodamceus austriacus, so I have 
given figures (3 and 15) of the venter and legs. 
Gymnodamceus Kulczynski 
Ewing, in 1917, 2 erected a new genus, Heterodamseus, 
and included in it his Bamceus magnisetosus ; 3 hut un- 
fortunately Ewing selected as genotype the European 
Bamceus bicostatus Koch, a species which Kulczynski, 
some fifteen years before, had selected as type of Gymno- 
damasus. Thus Heterodamaeus becomes a synonym of 
Gymnodomaeus. Jacot 4 says that Kulczynski 5 assigned 
no type ; however he is entirely wrong, for on page 43 of 
Kulczynski ’s paper is the statement “Typus Gymno- 
damceus bicostatus Koch. ” 
Gymnodamaeus pearsei sp. nov. 
Figs. 16, 27 
Dark reddish brown, border of abdomen appears black. 
Shape of body as in genotype, bicostatus, plainly longer 
than broad, not narrowed behind. Two tiny hairs near 
tip of head, and a longer one each side a little further 
back. Setae about as long as the space separating them, 
swollen toward tip, but the tip sharp. Legs extremely 
slender and very long, as in the long-legged Oribata. 
The front and hind femora have rather long basal stalk, 
then suddenly much enlarged, then tapering to the long 
slender apical part, this apical part is longer in front
