A REVISION OF THE ASTACID.E. 



spines. Carapace smooth, punctate, granulated on the sides, cervical groove 

 sulrutr. 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 antenna) with a strong sharp spine ; scale of moderate length, rather 

 broad, inner margin rounded, outer margin thick, turned outwards at the 

 tip. Third maxillipeds haiiy 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 is obsolete.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. Bai'tonii. 



Length, 48 mm. Carapace, 23 mm. Rostrum, 6 mm. Areola, 7 mm. 

 Breadth of areola, 2 mm. 



Saluda River, west of Greenville, S. C. Collected by Prof. D. S. Jor- 

 dan. Three specimens, one male of the second form, two females. For the 

 opportunity to examine these I am indebted to Prof. 0. P. Hay of Butler 

 Tuiversity, Irvington, Ind. Differs from the other species of the C. Bar- 

 lanii group in its long, gradually tapering rostrum, short metacarapace, 

 strongly developed spines of carapace, antennae, 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. Zolil. 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 

 iii;iv prove to be a distinct species from the Saluda River specimens. 

 T!u-y approach C. I>itr/n//, var. robusta, but may be distinguished from that 

 I'onn liy the longer-pointed rostrum, shorter metacarapace, better-developed 

 spines, etc.
