V. testa crassa, compressa, trigona, fumoso-fulva, laevigata, ob- 

 scure radiata et punctata, subsequilatera ; latere postico angulato, 

 radiatim striato, ad angulum subcancellato ; latere antico subtri- 

 gono ; lunula et area dorsali impressis, indistinctis. 



Very thick, smooth, triangular, flattish, of a smoky-brown 

 colour, and nearly equilateral ; the hinder side is angulated and 

 radiately grooved, and at the angle, particularly when young, has 

 a few cross grooves. The variety is an abnormal form, and 

 shghtly resembles the one figured as V. semkavicellata by Philippi.
