Nebraska, though apparently not extending into the Southern 
States. P. longipalpis is a southern form, —having been received as 
yet only from Arkansas,—which is remarkable for the extremely 
long palpi and abnormal chelicerze of the male, while in the 
female the palpi are of the usual length and the chelicerz nor- 
mal in form. 
Two species of the genus Oligolophus occur in our fauna. The 
first, O. pictus Wood, has been taken in Massachusetts, New York» 
Illinois, and Ohio. It is quite rare, though not so much so as the 
other, O. ohioensis Weed, which hasas yet been found only in Illinois 
and Ohio. 
Summarizing these statements, we find that, so far as at present 
known, the phalangid fauna of North America includes but twen- 
ty-two species, belonging to two subfamilies. The first subfamily, 
Sclerosomatinz, claims four forms, one of which belongs to Astro- 
bunus, while the generic position of the other three is at present 
in doubt. The subfamily Phalangiinz in 'udes four genera, viz., 
Liobunum with twelve species; Forbesium with two species; 
Phalangium with two species; and _ Oligolophus with two 
species. 
It must be confessed that, for the area | cbe, this is a very 
small showing, and undoubtedly the list will be greatly length- 
ened when the fauna of the mountainous regions and the more 
remote sections of the country is better known. France has a list 
of fifty-nine of this family, and the phalangid fauna of other Euro- 
pean countries is proportionately large.
