 Body very long but blunt at the end, consisting of fifty-nine segments besides the head; eyes consisting each of 

 six ocolli 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 tuberoles 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 unfreqnently found in caverns, where L. laclarium more rarely occurs. This well-marked 

 species may readily be distinguished from Lysiopetalum lactarium by the very short thick antennas, 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 these true cave-myriopods, Mr. Hubbard found a single specimen of Polydesmus gran- 

 ulatits 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. 



INSECTA. 



Thysanura. 



Lipura ? luciftjgus 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. 



Tomocertjs pltjmbeus Templeton, var. pallidtjs. 



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 Zwingle'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 

 antenna; are partly pale, the two basal joints 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 antennae 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.
