Others (fig. .5, 6), the body of the outermost three or four (fig. iaa, T), 

 as usual, of reduced size. 



The glanduliE salivales (5.0 or G.O 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 oesophagus 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, sanguines 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 o'jgene 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 3.0 mm. 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. 86) 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. Sd) strong, about 2.5 mm. long, the praiputium with 

 fine longitudinal folds (fig. 9), from the aperture upwards and nearly
