 t. 177. f. 1754 and 1755. 



Inhabits the coasts of the Nicobar Islands. Chemnitz. 



This shell appears by the figures to be eight lines long, and 

 about equally broad, and to possess some affinity with Tro- 

 chus Labeo; the pillar is said to have one obsolete tooth. 



ANGUis. 72. Shell transversely grooved, green with 

 blackish longitudinal zic-zac stripes, and the 

 inside pearly.

 a pale green colour with dark broad zic-zac longitudinal

Inhabits the coasts of New Zealand. Chemnitz. 



Chemnitz says this shell is called in England ' The knobbed 

 umbilicated Emerald Snail from New Zealand ;' and from his 

 figure it appears to differ from T. Anguis principally in be- 

 ing more than twice as large, and in not having the longitu- 

 dinal stripes undulated, or so strongly marked. 



UNDULATUS. 74. Shell ovate-convex, obtuse, gla- 

 brous, green with undulated black stripes, 

 and the throat silvery.
