increases in height ; then the teeth keep the same height and decrease 

 again in the outer part of the rows (fig. 5) ; the four to six interior 

 teeth are more erect, with shorter body and thinner hook (figs. 5, G). 



The salivary glands long, thin, whitish.^ The esophagus about 

 6 mm. long, rather wide, with strong longitudinal folds.- The stomach 

 small, included in the liver ; the biliary apertures as usual. 



The intestine issues through the liver behind the region of junc- 

 tion of the first and second third of the liver ; the first anteriorly pro- 

 ceeding part lodged in a groove on the superior side of the liver, not 

 passing beyond the antei'ior margin of that organ, about 2.5 mm. in 

 length ; the rest of the intestine about 10.0 mm. in length ; the diameter 

 of the intestine 0.8-1.3 mm. ; the longitudinal folds rather strong. 



The liver of yellowish color, more grayish on the surface; 9.0 mm. 

 in length, by a breadth of 5.5 and a height of 4.0 mm. ; the posterior 

 end rounded ; more than the anterior half of the under side, especially 

 its right part, is excavated (for the anterior genital mass) and behind 

 this is a deep transverse groove. The vesica fellea lying at the left 

 side of the offshoot of the intestine, rather small, in height about 1.25 

 mm., reaching nearly to the surface of the liver, nearly cylindrical. 



The heart as usual. The sanguineous glands whitish, rather 

 flattened ; the anterior obliquely triangular with the point, as usual, 

 adhering to the under side of the junction of the two cerebral ganglia ; 

 in length 2.0 by a breadth of 1.5 mm. ; the posterior transversely 

 elongate-oval, with a breadth of 3.5 by a length of 1.5 mm. The 

 renal syrinx melon-shaped, its largest diameter about 0.75 mm. ; its 

 free duct nearly three times as long ; a strong continuation of it pass- 

 ing along the floor of the rather large renal chamber, to the region of 

 the pylorus. 



The hermaphroditic gland spread in large groups of ramifications 

 over nearly the whole liver and by its brighter yellowish color some- 

 what contrasted with it ; in its lobules were masses of zoJsperHis and 

 rather small ojgene cells. The anterior genital mass^ in length 5.0 by 

 a breadth of 2.5 and a height of 4.0 mm. ; the right side rather con- 

 vex, meeting the more flattened left side at the sharp superior margin, 



^ They are in this way also mentioned by H. and E. (1. c, p. 215, PI, XII, 

 fig. 2cc) . 



2 The dilatation on the oesophagus mentioned and figured by H. and E. 

 (1. c, p. 215, PI. XII, fig. 2d) could not be seen in the specimen examined 

 by me.
