2. Diclidophora elongata, n. sp. 

 (PL X, figs. 9-10 ; PI. XI, fig. 8 ; PI. XII, figs. 1-2.) 

 Bodij lanceolate, anteriorly rather pointed, about 8 mm. long, the 

 pedicel of the hindmost pair of suckers inclusive, divisible only 

 into two parts, the body proper and the .caudal disc, the latter being 

 only about one-sixth the total length, and bearing on its margin the 

 long pedicels of the circular posterior suckers ; pedicels making 

 equal angles with each other, and each containing in its proximal 

 half a branch of the intestine and a portion of the vitellarium sur- 

 rounding the former. Oesophagus very short, 'i'he two intestinal 

 trunlcs sending out not very long lateral branches outwards, and con- 

 nected with each other by cross-commissures, which unite with each 

 other by means of secondary commissures ; the trunks continued into 

 each other at the posterior end of the body, thus forming here a 

 loop. From the loop are sent out at regular intervals eight, somewhat 

 long lateral branches, each of which penetrates into the pedicel of the 

 sucker as above mentioned. Common genital opening close behind the 

 termination of the oesophagus. Penis with eight hooks, Ovarij 

 occupying the posterior end of the middle third of the body, long, 

 cylindrical, bent on itself once at its middle and the whole again 

 bent on itself at its middle, so that the ovary has the form of a 

 double V one placed within the other ; with the angle of the V

 Fisches anzusehen ist " (MS).
