This species varies considerably both in form and in sculpture. The specimens 
from the Gulf of Siam are all rather small, with slightly prominent sculpture and, 
as the above measurements show, of ovately-oblong form; they come nearest to 
HAN.eEy’s T. inaequalis, but judging from the figures and descriptions I cannot see that 
that species is anything but a form of gargadia, to which species I have therefore 
referred my specimens. HipauGo! arrived at the same conclusion, when treating 
the specimens from the Philippines; he regards T. inaequalis, Hanl., to be synonymous 
with 7. gargadia L.
