Naturalist, p. 748, Dec., 1871). It may be remarked that, in the 
descriptions above referred to, Prof Cope, in stating the relative 
lengths of the joints of the antennz in each of the two species, 
omits all mention of the 6th joint; and, in the same manner, 
Prof. Packard omits the second. Prof, Packard's figures also 
represent only seven joints in the antennzy. Craspedosoma, as 
defined and figured by Gervais (Apteéres, vol. iv, p. 119, 
5; fig. 5), has the sterna and scuta consolidated into a complete 
ning as in Polydesmus and ulus, and therefore differs from this 
genus, as shown in plate 11, fig. 4, by a character considered of 
family importance.* 
Trichopetalum lunatum, sp. nov. PI. II, figs. 14. 
Dirty white, banded transversely and mottled with light 
brown anteriorly. Segments 28; males with 45, females with 
46 pairs of legs. Head large, dilated laterally, covered with 
short, erect, bristly hairs. Kyes (fig. 2) of 10 ocelli, in a lunate 
Oup, Convex toward the bases of the antenna. Antenne 
fig. 2) pilose, seven-jointed ; the joints measure, the first ‘(07™", 
second “10™™, third -23™", fourth *11™, fifth 22™, sixth oom, 
seventh ‘07™, First scutum semicircular, with the posterior 
margin slightly concave. Near the outer angles of this seutum 
are two small tubercles on each side, each bearing a stout 
bristle, and higher up a third tubercle on each side bears also a 
bristle. The remaining scuta (fig. 4) throughout are furnished 
with three bristles on each side, springing from tubercles, the 
two lower being approximate and situated on the upper surface 
of the short lateral processes, and the third higher up on the 
Scutum. On a few of the posterior segments these bristles are in 
a transverse row, and on the last scutum, which is broad and 
truncate, the two inner ones are thickened at their bases. 
here is an impressed dorsal line. Legs slender, white, hairy, 
with the penultimate joint lengthened. The under side of the 
Seventh segment of the male fig. 8) is furnished anteriorly 
Segment. In crawling these organs have a motion similar to 
that of the 
1 his species is not uncommon under or among decaying 
faves in moist woods about New Haven. 
* Since the above was in Prof. Cope, i article on the Wyandotte Cave 
. Cope, in an yandott 
and its Fauna (Am. ae Lng July, 1872, p. 414), has referred Sptrostrep 
( eudotremia) ; Packard to anew genus Scoterpes, which he characterizes as 
ek of eyes and lateral pores. Agreeing with Dr. Packard, he also doubts 
Validity of his own’ genus tremia, and refers P. cav r 
trephon, The lateral bear P. Vudiit are thus left somewhat doubtful, and with- 
Out actual examination it is impossible to decide whether or not it is congeneric 
With the species of Trichopetalum.
