194 SCIENTIFIC RESULTS OF THE 
specimen ; the cuticula of the lip disk as above. The tongue with 
ten rows of plates, further back eleven developed and two younger 
rows, the total number thus twenty-three. In the posterior rows of 
the tongue there were as many as thirty-four dental plates on each 
side of the rhachis ; they resembled those above described (fig. 6, 7). 
The salivary glands yellowish, ribbon-shaped. The stomach as 
above. The anteriorly proceeding part of the intestine 7.0 mm. long, 
by a diameter of about 2.0 mm.; the receding part about 20.0 mm. 
long, by a diameter of 1.5 mm. In the stomach and the rectum were 
pieces of a Keratospongia and different Diatomacea. The liver 23.0 
mm. long, by a breadth and a height of 11.0 mm.; the anterior end 
truncate, with a median deep and narrow slit for the cesophagus and 
for the intestine; the right anterior half of the liver rather excavated, 
especially beneath; the substance of. the liver yellow. 
The foremost glandula sanguinea about 4.5 mm. long, by a breadth 
of 2.5 ; the posterior 4.0 mm. long, by a breadth of 2.5 mm.; both very 
flattened (about 0.8 mm. thick), grayish-yellow. The kidney with its 
whitish network, contrasting prettily with the yolk-yellow hermaphro- 
ditic gland; the urinary chamber not wide; the tube on its floor thin. 
The hermaphroditic gland clothing nearly the whole liver (with its 
posterior end), as in the former specimen. ‘The anterior genital mass 
about 11.5 mm. long, by a height of 9.5 and a breadth of 5.0 mm., the 
ducts also projecting 3.0 mm. .The ampulla of the hermaphroditic duct 
yellowish-white, about 35.0 mm. long, by adiameter of 1.25 mm., run- 
ning across the upper part of the left side of the genital mass, and 
forming several windings on the anterior part of the upper margin. 
The large prostate as above (fig. 80), dirty yellow; 7.5 mm. long, 
by a diameter at the upper end of about 4.0 mm.; the part (fig? 8c), 
from which the spermatoduct proceeds, much brighter than the rest of 
the organ. The thin spermatoduct forming (fig. 8) a little coil at the 
upper end of the penis; when unrolled about 12 mm. long. This last. 
(fig. 8d, 9) organ strong, about 4.0 mm. long, by a diameter of 1.5 
mm.; the prominent orifice in the vestibulim (fig. 8e) with strong 
longitudinal folds; the glans conical, filling nearly half (fig. 9) of the 
cavity of the organ, the surface (under a power of 850) smooth. The 
spermatotheca whitish, spherical, with a diameter of 3.5 mm.; the 
spermatocysta short, sausage-shaped, about 4 0 mm. long, of reddish- 
yellow color. The duct from the spermatotheca to the vagina rather 
thick, 3.5 mm. long; the vagina larger than the penis, 6.0 mm. long, 
by a diameter of 2.5; the inside with fine longitudinal folds, and with
