Body very long hut blunt at the end, consisting of fifty-nine segments besides the head; eyes consisting each of 
six ocelli arranged in a straight line. The first segment behind the head is smooth, about half as long as wide, evenly 
convex, considerably broader than the head; the three succeeding segments are of about the same length, and each are 
about half as long as the fifth and succeeding segments. On the first segment are about ten bead-like tubercles seen 
from above; on the third about eight longer tubercles can be seen from above ; on the fifth and succeeding segments 
there are about nine dorsal and subdorsal high, prominent, thick, parallel ridges, becoming sharp behind. On the 
middle segments of the body about six sharp ridges with broad hollow valleys between can be seen from above. 
These are mounted on each side lower down by about twelve less distinct ridges, becoming towards the lower edge 
of the scuta less and less convex and distinct, until they are indicated by simple impressed lines. There are thus 
about thirty ridges in all on each scute. The segments (arthromeres) are short, and the smooth spaces between the 
rigid portions are very short above. The color of the body is horn brown, the head, feet, and antennae pale flesh- 
colored, and there is a dark median spot on the vertex between the eyes. The ridges are darker than the rest of the 
body. Length, 30 mm . 
Little Wyandotte Cave, Indiana, and Cave of Fountains, next to Weyer’s Cave, Virginia (Packard); Zwingle’s 
Cave, Carter’s Cave, Kentucky (F. G. Sanborn); Spruce Run Cave, on the- Kanawha River, Giles county, Virginia 
(Cope), Wyandotte Cave (Hubbard). One of the most abundant of the Myriopoda in the mountain region of Tennes¬ 
see and North Carolina (Cope). 
This species is not unfrequently found in caverns, where L. lactarium more rarely occurs. This well-marked 
species may readily be distinguished from Lysiopetalum lactarium by the very short thick antennae, linear eyes, and 
by the slenderer body, which, however, ends much more obtusely. We know of but one other species of Julidae with 
the eyes arranged in a linear series; this is the Trachyjulus ceylonicus Peters of Ceylon, figured by Humbert. 
The cave specimens which we have found are partially bleached, the result of probably a limited number of 
generations living in the darkness. 
Besides tliese true cave-myriopods, Mr. Hubbard found a single specimen of Polydesmus gran- 
ulatus Say, in Indian Cave, Barren County, Kentucky, not far from the mouth of the cave. It 
was bleached entirely white, although of nearly full size. Mr. Hubbard also found a bleached 
specimen of the same species-in Lyon Cave, Kentucky.

Thysantjra. 
Ltpura ? lucifugus n. sp. Plate XYI, fig. 1. 
A small species of uncertain genus, with short, three-jointed antennae, and with distinct eyes, 
occurred in Wyandotte Cave. 
Tomocerus plumbeus Templeton, var. pallidus. 
One specimen from Zwingle’s Cave was but slightly changed, being almost wholly plum¬ 
beous; it occurred one-quarter of a mile from daylight (Sanborn). 
In a number of other specimens from Zwiugle’s Cave and others of the Carter caves the body 
is white, as well as the spring and the legs, but the tarsi retain a slight plumbeous tinge. The 
antennae are partly pale, the two basal joiuts being bathed with leaden gray. Ten examples col¬ 
lected by us had distinct black eyes, but minute and angular in outline, having suffered a 
considerable reduction in size. Specimens collected by us from the ice-house cave were white, 
with dusky autennae and black eyes, and were like those just described. 
Specimens from X Cave were all bleached, like those from the other Carter caves, but in 
some examples the eyes were connected by a narrow black band.
