68 A REVISION OF THE ASTACIDA. 
spines. Carapace smooth, punctate, eranulated on the sides, cervical groove 
suleate, sinuate ; a sharp lateral and branchiostegian spine ; suborbital angle 
rounded; an irregular indentation on the side of the carapace, below the lat- 
eral spine, on the hepatic region and anterior part of the branchial region ; 
areola broad, smooth, punctate, less than half as long as the distance from 
the tip of the rostrum to the cervical groove. Telson bispinose on each 
side. Epistoma triangular, angles rounded. Second and third segments of 
the antennze with a strong sharp spine; scale of moderate length, rather 
broad, inner margin rounded, outer margin thick, turned outwards at the 
tip. Third maxillipeds hairy within. Chela moderate, punctate, serrato- 
tuberculate on internal border, fingers setose on their inner margins, ex- 
ternal border of outer finger submarginate. Carpus armed with a strong 
internal spine and smaller inferior median and external spines. Meros with 
well-developed biserial spines below, and two obliquely placed near the dis- 
tal end of the superior border. In some specimens one of the superior pair 
is obsolete. Third pair of legs hooked. First pair of abdominal appendages 
as in C. Bartonit. 
Length, 48 mm. Carapace, 23 mm. Rostrum, 6 mm. Areola, 7 mm. 
Breadth of areola, 2 mm. 
Saluda River, west of Greenville, 8. C. Collected by Prof. D. 8. Jor- 
dan. Three specimens, one male of the second form, two females. For the 
opportunity to examine these I am indebted to Prof. O. P. Hay of Butler 
University, Irvington, Ind. Differs from the other species of the C. Bar- 
toni group in its long, gradually tapering rostrum, short metacarapace, 
strongly developed spines of carapace, antennee, and meros. The acumen 
of the rostrum is scarcely upturned at the tip. 
Specimens from North Carolina, Old Fort, McDowell Co., and French 
Broad River (in Mus. Comp. Zodl. and Acad. Nat. Sci. Phila.), differ from 
the above in having the rostrum flatter and less attenuated at the tip, a 
shorter antennal scale, sub-orbital angle produced into a sharp spine. These 
may prove to be a distinct species from the Saluda River specimens. 
They approach OC. Bartoni, var. robusta, but may be distinguished from that 
form by the longer-pointed rostrum, shorter metacarapace, better-developed 
spines, ete.
