Clitellum complete, viii-wx. No ventral sete in xviii, but sete 3 and 4 present. Prostate 
pores on large papilla, the four papille being close together in the sunk clitellar pit. 
Oviducal pores on a large median papilla, but the pores are separate and on a line drawn 
hetween the sete. Penial sete, largest slightly hooked with 8 indistinct notches, smallest 
with a hair-like sigmoid tip. Spermathece, the apical-sac not globular, basal part 
with a swell diverticulum.  Sacculated intestine commences in xix.  Typhlosole in xx-xiv. 
Oaleiferous diverticula 3 pairs in avi, xvii, voi; the anterior one is much smaller.

calomic mantle. Color pale flesh, no pigment. Habitat, Tepic, Mexico, 4000 feet. 
Benhamia octonephra Rosa. 
Derrition. Compiled after Rosa. Length 20 to 40 mm.; number of somites 
85 to 95. First dorsal pore between » and vi. Clitellum incomplete, in aiii to xx.  Pe- 
nial sete, the larger with six groups of two blunt tubercles; the smaller seta like a scalpel. 
Common sete, couples equidistant. Oviducts open into a single median pore on a slight 
swelling. Calciferous diverticula three pairs in xv, xviand xvii. Sperm-sacs in xi and 
vit. Nephridia micronephric in four rows on either side. Spermatheca, basal part 
pear-haped with a globular diverticulum. Habitat, Paraguay.

and corrugated. Clitellum incomplete, in wiii to wx. Penial sete, largest with five 
notches; smaller seta forked with prongs of equal size. Common sete pointed and ven- 
tral. Oviducts open jointly in a median pore. Gizzard in vii and viii. Calciferous di- 
verticula in xv, xvi and xvii. Nephridia micronephric in four rows on either side. 
Typhlosole present. Spermatheca much flatiened. Color reddish flesh. Habitat, Cal- 
ifornia, in hothouse (imported).

Derinition. Length 90 mm. by 4 mm.; number af somites 174. Skin pig- 
mented anteriorly.  Clitellum incomplete (xiii) xiv to wx. Penral sete slender with nu- 
merous irregular notches; muny set in each sac. The curved fossa between the pros- 
tate pores with the convex side toward the median line. The anterior prostate largest. 
Caleiferous diverticula three pairs. Nephridia plectonephric. Spermatheca without diver- 
ticulum, but with warty protuberance. Color, anterior pale reddish, posterior part gray. 
Habitat, Hayti (?).
