The type is so close to P. paten.^, Hombr., that I suspect them 

 to be identical ; in which case the latter name will take prece- 

 dence. Mr. Velain has selected from the numerous forms of this 

 species the following named varieties : 



Var. multiatriata. fig. 172. 



Var. semicostata, fig. 170. 



Var. cincta., fig. 162.
