ON THE CIIILOPODA OF NORTH AMERICA. 11 



portions of the scuta are a very light brown. The scutal stomata are very large and 

 look upward, but scarcely at all backward. But one of the antenna; is preserved; it 

 appears to be one and a half times the length of the body. Distal portion of the legs 

 a rather bright ferruginous. The distal metatarsi are scarcely one-half the length of 

 the proximal. The rows of spines, that commonly serrate the legs in this genus, are 

 obsolete, and the metatarsal joints have none. The ventral surface is a very light 



olive.

C. STRABA n. sp. — C. ferruginea, fascia mediana unica indistineta ; capite lato, minute dense puuetato 

 appendicibusque sparse pilosis, depressione lato et linea longitudinale mediana et utrinque altera cur- 

 vata ante oculuin et altera transversa indistineta inter oculos insculpto ; scutis spinulis parvis asperatis, 

 minute dense punctatis, vis imbricatis, postice emarginatis, marginibus valde elevatis et spinosis et cre- 

 nulatis; pedibus ferrugineis, articulo metatarsali primo sequentibus septem conjunctis in longitudine 

 sequali. 

 As our specimen has been preserved for some time in alcohol, the original color 

 may have been lost. The very prominent eyes in this species contrast strangely with 

 the almost livid hue of the animal. The median fascia is rather lighter than the 

 remainder of the body, but is very indistinct. The posterior border of the scuta is 

 furnished with two small approximate gibbosities, and is of a lighter shade than the 

 remainder. The dorsal stomata look upwards and a little backwards. Spines of the 

 genual articulations are long and slender: those of tibio-tarsal not so long; those sur- 

 rounding metatarsal very small. Distal portion of the leg pubescent. The spines 

 that serrate the numerous ridges on the legs are uncommonly large and of a red color. 

 Sterna furnished with the usual central groove.

q n . S p.?_C. dilute viridis, fascia media et altera utrinque saturatioribus ; capite breve, antice

 Head marked very similarly to G slraha. Legs with the usual complement of 

 spines. The anterior apparently destitute of annuli, the posterior equalling if not 

 exceeding the antennas in length. Are the antennae broken in our specimen? The 

 femur is provided with one, rarely two, incomplete rings of dark green, the tibia and 

 tarsus each with two complete annuli. The general color of the legs is a light yel- 

 lowish green, their distal extremity inclining to rufous. The scuta have the median 

 fascia better marked than the lateral, and are furnished posteriorly with two smooth
