Plicatoperipatus subgen. nov. 



Genotype. — Peripatus jamaicensis Grabham and Cockerell, 1892. 



Diagnosis. — The dorsal transverse folds number twenty-four to each 

 segment, and are always very indistinct as a result of the numerous and 

 irregular anastomosings of the furrows which separate them; the primary 

 papillae of the hack are small and subequal ; accessory papilla* are rare or 

 absent; crural tubercles occur on the two pregenital pairs of legs in the 



male.

 where some of them ordinarily bifurcate; the primary papillae of the back 

 have quadrangular bases, being separated by grooves parallel to the 

 longitudinal axis of the body; the accessory tubercles are ordinarily 

 small and few in number; crural tubercles are present on the two pre-
