192 SCIENTIFIC RESULTS OF THE 
others (fig. 5, 6), the body of the outermost three or four (fig. 4aa, 7), 
as usual, of reduced size. 
The glandulz salivales (5.0 or 6.0 mm.) long, in the anterior part 
about one-third larger than in the rest, measuring 1.0 mm. in diameter, 
yellowish ; in the rest of the length much narrower, whitish. 
The cesophagus is about 9.0 mm. long, rather wide. The stomach 
is included in the liver, not spacious. ‘The intestine appears on the 
surface of the liver in the usual manner, passing forwards, forming a 
short flexure, and running straight backwards to the anal tube, which 
has ‘in its interior many fine longitudinal folds; the total length of the 
intestine about 20.0 mm., with fine longitudinal folds through its whole 
length. The cavity was empty. The liver yellowish, about 17.0 mm. 
long, by a breadth of 8.0 mm., and a height of about 6.0 or 7.0 mm. ; 
the anterior end truncate, the posterior end rounded ; on the right side 
of the forepart a flattened impression for the anterior genital mass. 
The vesica fellea, as usual, behind and at the left side of the pylorus, 
elongate-pyriform, grayish, taken together with its duct about 2.5 mm. 
in length. 
The heart as usual. The two gland. sanguinee as usual, whitish ; 
the foremost more triangular, about 3.5 mm. long; the posterior 
broader, about 2.0 mm. long. 
The gland. hermaphrodisiaca with a rather thick yellow layer 
clothing the greater part of the surface of the liver (except the pos- 
terior end); in the lobules of the organ were rather large odgene cells 
and masses of zoJsperms. The anterior genital mass large, com- 
pressed, about 10.0 mm. long, by a height of 6.3 mm., and a breadth 
of 3.0mm. ‘The ampulla of the hermaphroditic duct strong, grayish, 
when unrolled about 25:0 mm. long, somewhat coiled on the anterior 
end of the left side of the mass and on its inferior flattened edge be- 
hind the large prostate; it reaches a diameter of 1.2 mm. The male 
branch of the ampulla (fig. 8a) thin, white, passing into the narrow 
inferior end of the prostate, thus forms the fore-end of the whole 
genital mass. The prostate (fig. 8b) is of dirty yellow color, flattened 
and irregularly pyriform, the length about 6.3 mm., by a breadth of 
as much as 3.0 mm.; the spermatoduct (fig. 8c) issuing from the 
upper part of the posterior side of the gland, in its first thicker part 
nearly as long as the prostate; in the rest of its length thinner, mak- 
ing several coils and passing (fig. 9a) into the male organ. ‘The re- 
tracted penis (fig. 8d) strong, about 2.5 mm. long, the preputium with 
fine longitudinal folds (fig. 9), from the uperture upwards and nearly
