22 Arnastra {Laminella) kuhnsi. 



This species differs ixoxxvA. ereda Pse., as all the specimens are 

 sinistral and are minutely perforate. The brown epidermis covers 

 the whole of the shell and is not fugacious as in all the other 

 species of Laminella. The darker zigzag markings are in the 

 epidermis and are, also, not fugacious. There is a straw-colored 

 variety of which I have seen a single specimen.
