distal to cingulum enlarged, becoming smaller again at a point about 

 midway of length of postcingular portion; distal half of postcingular 

 portion twisted so that erstwhile outer surface becomes caudal surface 

 and inner surface becomes cephalic surface; end of telopodite not very- 

 acute. Precingular portion of telopodite longer than postcingular 

 portion. Prefemoral spine absent. 



Color of all specimens at hand faded. 



Type locality: Natural Bridge, Powell County, Ky. Known 

 only from the type locality. 



Type specimens: Collected by H. Garman. Male holotj^pe col- 

 lected Oct. 21, 1911; male paratype, May 5, 1895. Both specimens 

 were sent to Dr. Nell B. Causey of the University of Arkansas, who 

 placed the holotype m the American Museum of Natural History and 

 the paratype in the U. S. National Museum. 



Discussion: Although this species resembles separanda in having 

 the proximal part of the postcingular portion of the telopodite of the 

 gonopod enlarged, the resemblance seems to end there and it is felt 

 that this does not indicate any close relationship. 



This is one of the few known forms of Brachoria where the pre- 

 femoral spine seems to be typically entirely absent. 



Study of these specimens was made possible by the cooperation of 

 Dr. Causey, who loaned them to me. 



The name refers to the twisted distal portion of the telopodite of 

 the male gonopod.

Diagnosis: Distinguished from all other species of the genus 

 except hansonia, ochra, cedra, hubrichti, and calcaria by the com- 

 pletely simple form of the telopodite of the male gonopod. Differs 

 from hansonia in having an enlargement of the telopodite just distal 

 to' the cingulum and in having two rather abrupt bends in the telo- 

 podite. Differs from ochra and cedra in the first of the two characters 

 mentioned. Diflei-s from hubrichti in the more slender and acuminate 

 form of the telopodite. Resembles calcaria but lacks teeth on the 

 precingular portion of the telopodite and the telopodite is more 

 slender. 



Description: Length of male holotype, 32 mm.; width, 6.5 mm.; 

 length of other males, 34-38 mm. ; \vidth, 8-9 mm. 



Collum ellipsoidal, edges gently curved, ends of paranota broadly 

 rounded; paranotal swellings usually absent; ridges on cephalic 

 margins of paranota usually absent.
