Strand of Koh Mak and Koh Kahdat (-/a). 



Long. 20-28 mm. 



Distribution: — Gulf of Manaar. — Tonga Isl. 



From the descriptions and figures of Reeve's species ovum, tumida, and pila, 

 it is not possible for me to form an opinion of their reciprocal relation and posi- 

 tion to vesicula, Gould, and so I have adopted the name of Gould's form vesicula, 

 which entirely agrees with the specimens from the Gulf of Siam.
