34 OLIVA. 



175. piperita (f. 402, 403), Marrat. — Quarn 0. tergina 

 gracilior, dorso punctato-lineata. — Like 0. tergina in form 

 and. general character of markings, but, peppered with 

 minute dots forming the lines and angles of the pattern. 



176. zanoeta (f. 404). — 0. tergince forma similis, sed 

 gracilior, castaneo late trigonata; columella rectiuscula. — ■ 

 Like 0. piperita, this is more slender than 0. tergina, and 

 has not the anterior projecting tooth-like fold of that species. 

 The two broad chestnut bands, one above the belt and the 

 other beneath the suture, and the narrow one upon the belt 

 will prevent this from being mistaken for any other species.
