CHAMBERLIN: THE CHILOPODA OF BRAZIL. 203 
Spiracles all circular; the first one much larger than the second and 
the latter likewise considerably larger than the third; the others 
gradually decreasing caudad, in the posterior region becoming minute. 
The first sixteen sternites with the caudal border produced at the 
middle, the distinct process in each case fitting into a corresponding 
excavation in the succeeding segment. Ventral pores present on all 
sternites excepting the ultimate; on the sternite as far back as the 
twenty-fifth or twenty-sixth, the pores are in a single distinct sub- 
circular area; caudad of this the areas are more irregular, with a 
distinct tendency for each to become longitudinally divided into two 
areas or geminate. 
Last ventral plate very wide; sides nearly straight, strongly con- 
verging caudad; caudal corners rounded; caudal margin a little 
crenately incised a little each side of the middle. Rather densely 
clothed with fine short hairs, especially on the caudal portion. 
Coxopleurae subdensely clothed over the ventral area with fine short 
hairs. | 
First pair of legs shorter and more slender than the second, the next 
few pairs gradually attaining the full size; anterior pairs of legs con- 
spicuously more robust than the posterior ones. 
Anal legs in the female much longer than the penult; very slender. 
Ultimate joint longer than the penult, very slender and ending in a 
minute membranous point but with no trace of a real claw. Hairs 
long and sparse. (Plate 5, fig. 3). Pairs of legs fifty-nine. 
Length 40 mm. 
Locality — State of Parahyba: Independencia! (Mann and Heath). 
The present species differs from plusiodonta (Attems) in the much 
greater length and different shape of the cephalic plate, this in plusio- 
donta being only about as long as wide; in having the prebasal plate 
exposed; in the greater number of pairs of legs; in the character of 
the ventral pore areas, etc. The two species are similar in regard 
to the processes and pits of the anterior plates.
