t Half grown shell. It presents a very different appearance from the adult. 



g Half grown shell. . 



[This shell is narrower than G. laeta, resembling harpa in form ; but the aperture is wider and 

 more rounded below. It is very closely allied to G. excavata, which is a smooth species, however .
