Hah. — Chekiang, China. Three specimens collected by Messrs. 

 J. J- Walker and Basset Smith. 



Animal (PI. iv, fig. 4) globose anteriorly, tapering posteriorly; 

 ground colour yellow or 3'ellowish-brown, varying to a deep brown, 

 usually with a faint median and two irregular lateral bands, sides of 

 body marked with brownish spots or blotches; colour subject to much 

 variation. Mantle covers the whole of the dorsum. Peripodial groove 

 distinct. Foot-fringe yellowish with brownish lineoles. Foot-sole 

 yellow, not divided into median and lateral planes. 



Length (in alcohol) 39 mm., foot-sole 12 mm. broad. 



Anatomy. 



The Generative Organs (PI. v, fig. 14). — The vestibule is a large 

 globose sac, on the inner (left) side of which the penis opens, this 

 organ is a wide muscular tube twisted and folded upon itself, its distal 

 end is expanded and on the under side of this the vas deferens joins 

 the penis (PL v, fig. 14, v.d.). In all the specimens dissected, the 

 form of the penis was constant, always being expanded at its distal 

 extremity and folded upon itself. The vas deferens is a short convo- 

 luted tube lying dorsal to the free-oviduct. The receptaculum seminis 

 is a large somewhat triangular shaped sac, it has a long duct which 

 becomes slightly larger just before opening into the vestibule. The 

 common duct is folded upon itself twice, the oviducal portion being 

 much convoluted. The albumen gland calls for no special mention. 

 There is a long convoluted hermaphrodite duct, and a large hermaph- 

 rodite gland divided into a series of lobules. 



Affinities. 



Respecting the affinities of T. hilineatus, I am able to say very 

 little, owing to the lack of any details respecting the anatomy of the 

 majority of species of this genus. In the form and structure of the 

 digestive and generative organs it is related distantly to T. striatus, 

 Hass. It is very distinct from T. caroliiiensis, Bosc.
