tudiual folds ; in this part opened from each side the bile-duct 

 (figs. 6c, Ice) and a little more backwards the intestine (figs. 6, 7). 

 Through the posterior part of the stomach shone the belt of the 

 stomachal plates (figs. 6, 7). This belt was formed of 8 brownish 

 yellow plates of usual form with 1-3 intermedian smaller. The short 

 intestine stomach-like dilated in its first part, with several small 

 pocket-like widenings arranged in a series (fig. 6c/) on the anterior 

 margin, with fine oblique folds on the inside ; from this widened 

 part issues a stronger fold, which with several thinner ones runs 

 through the length of the intestine (fig. 6e). The total length of 

 the intestine 9 mm. — The contents of the alimentary cavity were 

 animal matter with remains of small Hydroids. 



The three 2^^"^''icipal liver-branches with their ramified hepatic 

 ducts and the principal branchlets to the dorsal epinotidia as usual, 

 but in these last clearer (not so yellow) ; the epinotidial hepatic trunks 

 not reaching the point of the organs and their branchlets scarcely 

 entering in the nodules ; through the axis of the papillae moreover 

 two vessels and muscular fibres, which cause the often very notable 

 contraction of the epinotidia. The nodules of these are again finely 

 nodulous (fig. 8), and each of the minimal nodules possesses a few 

 glandular cells. 



The net-work of the liver-branches is interwoven with the much 

 branched renal tubes (figs. 9, 10), the branches reaching the root of 

 the epinotidia, but did not seem to ascend into them. The renal cells 

 reaching a diameter of 0-025 mm. (fig. 11). 



The large yellow lobules of the hermaphrodite gland filling a 

 great part of the hinder cavity of the body, wrapped up and often 

 concealed by connective tissue and by closely adhesive hepatic 

 branches and lobules. They were chiefly globulous, of a diameter 

 up to 3 mm., their number only about 20 ; their structure as 

 usual. 



The anterior genital mass large, 8-5 mm. long by a breadth of 4 

 and height of 5, white and yellowish. The yellow hermaphrodite 

 duct long, twisted. The ovigerous duct did not seem to have a 

 "fan-shaped" organ (as in the M. capucina). The seminal vesicle 

 small, pear-shaped, 2 mm. in its greatest diameter; the rather strong 

 duct somewhat winding. The globular prostata has the anterior 

 somewhat flattened, and the navel here is deep ; it is yellowish, of a 

 diameter of 3'5 mm., finely granulated on the whole of the surface ; 

 its duct rather strong, 4 mm. long. The praeputium thin, 3 mm. 

 long ; the pointed glans (fig. 12) shone through throughout its whole 

 length. The chiefly white mucous gland formed the largest part of 

 the anterior genital mass.
