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 Goutp’s form vesicula, 
which entirely agrees with the specimens from the Gulf of Siam.
