the outside and inside. The whitish seminal duct making several 

 windings, when unrolled 2-5 cm. long, continued in the blackish 

 penis sack (pripputiuni) of a length of 4 mm., the inside of this with 

 fine longitudinal folds, at its base the small glans. This last has the 

 usual armature of (quincuncial) series of slightly yellowish hooks 

 (tig. 15) rising to a height of 002 mm , the armature continued for a 

 short distance up in the seminal duct. The spermatotheca (fig. 16a) 

 globular, of a diameter of 2-3 mm., greenish blue on account of its 

 dark contents (of usual kind) ; the spermatocysta (fig. 16h) smaller, 

 whitish, pear-shaped, containing zoosperms. The mucous and albu- 

 minous gland whitish and white ; into the anterior end opened a 

 thin-walled bag (vestibular gland ?) (fig. 17) of the length of 4-5 mm. 

 the inside of which show'ed closely set fine reticular folds. 



The whole of the intestines was wrapt up in a loose, somewhat 

 felt-like, colourless connective tissue, and the different parts of the 

 intestines were connected by a similar substance. 



The form here examined is certainly new ; it approaches perhaps 

 nearest to the N.flia2}hana of the Pacific Ocean (Aibukit).* Regard- 

 ing the salivary glands and the presence of a vestibular bag, it seems 

 to differ from the hitherto known species of the genus.
