610 A New Genus of Minute Pauropod Myriapods. (October, 
of habitat they make, but all of the specimens I have yet col- 
lected were taken from the under side of fallen limbs in damp, 
shady situations on the ground, not under the bark of trees. 
Eurypauropus in some respects is a good deal like Polyxenes' in 
the shape and superficial ornamentation of its segments, but the 
dorsal serrate plumes and caudal fascicles of hooked bristles are 
deciduous in the latter, and may be readily brushed off, which is 
not the case with the tubercles and spines of the former. 
In view of the fact that Evrypauropus differs from Pauropus in 
the same way that Polydesmus differs from ulus, in having the 
legs concealed by the lateral 
expansion of the body seg- 
ments, as shown in the accom- 
panying cut, where Fig. I rep- 
resents a diagrammatic cross- 
section of Aurypauropus and 
Fig. 11 the same of Pauropus, 
as well as in having the head 
overhung by the anterior, lat- 
eral and downward production 
II of the chitinous shield-like 
first segment, and that it has 
fewer segments than any other 
species of Myriapod, I venture to consider it a family under the 
name of Eurypauropodidæ. The following revision of the order 
becomes accordingly necessary. 
PAUROPODA, Lubbock, Trans. Linn. Soc., XXVI, p. 181. 
Body composed of 6-10 segments, convex or depressed, with 
scattered hairs or tubercles and spines. Antennæ five-jointed, 
bifid, bearing three long, jointed appendages. Nine pairs of legs; 
feet with a claw and pulvillus. Herbivorous. 
I. Pauropopip#, Lubbock, 1. c. 
Segments ten, the chitinous annuli of which are circular 
1 Adverting to Polyxenes, I find that its eggs are usually more or less entangled in. 
a felt composed of the caudal bristles, which is, no doubt, a protection against the 
ravages of the long-snouted mites, and I also find that the singular barbed hooks of 
these bristles in P. fasciculatus Say, ere different in form from those of P. lagurus 
of ee according to the recent figures of Bode. 
f. Leidy has recently informed me that he has lately found P. fasciculatus at 
it Pa., which is the fourth locality known to me for this species, making its 
present distribution extend from Massachusetts to Georgia.
