developed, so that the total number was 25. There appeared to be up to 25 lateral plates 

 in the series on either side of the median one. The plates were yellowish; the breadth 

 of the median one was O^O 1 ™, the height of the hook of the inmost lateral ones was 

 Q-jOmm ) an d rose gradually to OIS 111111 , whereupon it decreased towards the end of the 

 series; the height of the outmost but one was O'H™ 1 , that of the outmost one 010™™. 

 The median plates (fig. 4 a, 7| were of the kind common in related forms, and showed rather 

 spread legs connected by a thinner part; the pointed hook of the highly recurved fore 

 edge was dentate, and on either side of this hook (3 — ) 4 denticles were seen. The three 

 inmost lateral plates (fig. 5) were more clumsy, and the hook af these plates was lower; 

 the inmost one (fig. 5 a) had on the inner edge one, one the outer edge 1 — 2 denticles; 

 the following ones had no denticles inwardly, but 2 — 3 outvardly. On the following 3 (—4) 

 lateral plates (fig. 4 b) two denticles were found on the hook; the following ones (fig. 8) 

 had only one denticle, and on about the ten outermost ones no denticles were found 

 (fig. 37, 8). 



The whitish salivary glands had a length of 5°™; they were slender Ifig. 9 b), 

 covered with fine tubercles, and reached to the middle of the stomach, one was attached 

 above the cardia, the other below the same to the right. 



The oesophagus was whitish, of a length of 3™™, a little wider at the cardia 

 (fig. 9 a). The stomach (fig. 9 c) was somewhat irregularly globular or short pyriform, of 

 a length and a diameter of 5°™; the foremost part of it was somewhat thin-walled, while 

 the posterior, more yellow part was very muscular and thick-walled. On the inner side of 

 the latter part were found 8 larger and about 12 smaller stomach-plates in two circles dis- 

 placed among each other. These plates were, as it were, pyramidal, somewhat bent; their 

 base had a diameter of up to 2'5 mm , was egg-shaped, angular-roundish or -oval; their height 

 was smaller than the base, they were tapering to the top, or ended in a little angular flat, 

 were of a cartilaginous firmness, translucent bluish, and showed the common, finely irides- 

 cent axial or subaxial column. In and at the pylorus of the posterior stomach, which 

 had a length of about l'ô 111111 , several series of smaller stomach-plates were seen: they 

 were lower, conical, not so hard as the above mentioned, and their base had a diameter 

 of up to O^ö 1 ™ 1 . — The intestine (fig. 9 f) rising from the pylorus of the posterior sto- 

 mach, was to begin with scarcely thicker, of a diameter of 2™™, in the other part some- 

 what thinner ; the first part of it was situated in a furrow of the right side of the fore 

 end of the liver, then it turned to the left covered by the liver, appeared next at the left 

 side of the liver, bent forward, left the upper edge of the fore end of the liver to the 

 right, turned again to the left covered by the liver, appeared again backwards at the left 

 edge of the liver, at the posterior end of which it formed a large winding, and rose to 

 the anal papilla (fig. 1 c, 9 g). The whole length of the intestine was about 5'5 cn1 -. by a dia-
