A PERTPATUS FROM GUATEMALA.

* 



No Peripatus has hitherto been known from Guatemala, but 

 Mr. E. Bethel, the well-known naturalist of Denver, when 

 recently at Puerto Barrios, found a specimen which he has 

 kindly placed in my hands for description. It will later be 

 transmitted to the U. S. National Museum. 



Peripatus (Epiperipatus) biolleyi Bouvier, var. betheli v. nov. 



Female. — Length 34 mm., rather slender, width in middle ahont 4% 

 mm.; thirty pairs of legs; above uniform dark wood brown, without 

 markings; antennas blackish; ventral surface pallid, with a brownish- 

 lilac tint; body densely tnbercnlate, the transverse folds fairly distinct, 

 but in places obscured by the irregularity of the tubercles or papillpe ; 

 laterally, however, the folds are as well defined as dorsally; no median 

 dorsal line; many of the papillfe are elongate and conical; accessory 

 papillae few, but primary ones very diverse in size; foot-pads and neph- 

 ridial tubercles essentially as in biolleyi ; nephridial tubercle between the 

 third and fourth pads, independent, the fourth pad well developed, not 

 divided; all the pads large and broad, as in biolleyi; outer blade of 

 mandibles as in biolleyi ; inner blade nearly as in biolleyi; the peculiar 

 second (accessory) denticle shaped as in biolleyi, and the third (rudi- 

 mentary) one also as figured by Bouvier, except that the angular point 

 is more pronounced; the row of small teeth beyond consists of 9, instead 

 of 10 or 11 as in biolleyi. 



Peripatus biolleyi was described from near San Jose, Costa Rica, on the 

 divide between the Atlantic and Pacific slopes, at an altitude of 1,1 (il 

 meters. Other specimens were found on the Pacific slope at an altitude 

 of 250 meters. The species 1ms not been found outside of Costa Rica, 

 but a specimen of Peripatus having 30 pairs of legs was found in British 

 Honduras, and is briefly noted by Brues in Bull. Mus. Comp. Zool., 

 LIV (1911), p. 317. Tins latter was so poorly preserved that it could not 

 be determined, but I suppose that in all probability it belongs to betheli.
