ie ASHFORDIA GRANULATA. 
The REPRODUCTIVE ORGANS consist of a somewhat compact and narrowly tri- 
angular OVOTESTIS which is constituted by an aggregation of whitish CCA ; the 
HERMAPHRODITE-DUCT becomes much convoluted as it approaches the distinct 
VESICULA SEMINALIS ; the ALBUMEN GLAND is of the usual linguiform shape; the 
OVIDUCT is very sacculate ; the SPERM-DUCT or prostate is conspicuously broad, 
and composed of loose, short, opaque white rods ; the SPERMATHECA is large and 
somewhat triangulate, supported by a stoutish stem about half the length of the 
oviduet ; the VAGINA, though somewhat dilated, shows no traces of the dart-saes

and mucus-glands which at one time were probably present ; the PENIS-SHEATH is 
very tumid and abruptly dilated at its junction with the ATRIUM, its distal end is 
longitudinally striped with opaque-white lines, and separated from the proximal 
moiety by a slight constriction, the tumidity of the organ suggests the possibility 
of the presence therein of a sarcobelum or excitatory organ ; the EPIPHALLUS is 
fairly long and cylindrical, the PENIAL RETRACTOR being aftixed near its proximal 
end ; the FLAGELLUM resembles a short spike. 
The RADULA is of the usual oblong shape, about 2 mill. long and ? mill. wide, 
with an average of 120 sinuate, transverse rows of teeth, each row composed of 
the usual three series, the median, the lateral, and marginal areas. The median

row is characterised by a somewhat quadrate base, possessing a moderately deve- 
loped mesocone, with a feeble and insignificant ectocone at each side; the laterals 
are about ten in number, and show a mesocone which increase in size and strength 
and whose ectocone also increases in size as the teeth recede from the centre, while 
the endocone is only indicated ; the marginals are about fifteen in number, and are
