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 

 Hanley's T. inaeqiialis, 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. Hidalgo' arrived at the same conclusion, when treating 

 the specimens from the Philippines; he regards T. inaeqiialis, Hani., to be synonymous 

 with T. gargadia L.
