greater part ovcrroofed by the penultimate, which is broader than 

 usual. The legs are minutely hairy. 



The color of this animal in life is a delicate rose color, whitish at one 

 extremity and shading into orange at the other. 



The number of the annuli in the adults I find to be fifty-three down 

 to fifty-one. In specimens a little smaller there are forty-six and four, 

 and in the smallest and palest colored, hence younger, the number 

 ranges from forty-three to thirty-nine. 



The locality whence I obtained this species is on the western slope 

 of the Cumberland mountains, in the northern part of East Tennessee. 

 I found them under masses of chestnut bark in two places, in small 

 families of some size, with Fol^desnuis. They have the motions 

 of Polydesmi, i. e. they progress slowly and roll themselves up when 

 captured. 



This form is near Wood's Octoglena, of which one species, {0. hivir- 

 gatii) was found in northern Georgia. It differs generically in the 

 great extent of the basilar segment, which is very short and leaves the 

 head exposed in Octorjlena, and in the agglomeration of the ocelli, 

 which, in the latter, are arranged in two long series of four each. 



The annuli appear to be completely chitinized on the median line 

 below. 



Ohservafions on other Mi/riapoda. 



The Bracliycijhe lecontei, Wood, occurs in Jeiferson County, in the 

 Valley of East Tennessee. It is not very common and lives under 

 bark of fallen logs. The structure of its head is much like that of 

 Andfognatlim externally, and the genus is probably to be referred to 

 the Andrognathidae rather than to the Siphonophorida). It differs 

 from the former genus in marked characters, the confluence of the 

 last three articulations of the antennae being the most important. 



The Cambala annidata Say, (Cope, Proceed. Amer. Philos. Soc. 

 1869, p. 181,) is one of the most abundant of the Myriapoda in the 

 mountain regions of Tennessee and North Carolina. It is more abun- 

 dant than the Spirostrephon lactarius, which it considerably resembles, 

 and with which it is found under bark, etc. 



As is known, the Myriapoda of the orders Strongylia and Sugentia, 

 are sluggish in their motions and not furnished with offensive weapons. 

 They therefore produce secretions of a very acrid character, which fur- 

 nish a secure defense against many enemies. The species of Spiroho- 

 lus and Jidus discharge a yellowish juice having much the smell of 

 aqua regia,and a very acrid taste. The Spirostrephon lactarius exudes
