illustration for haciUum. Desha3'es' figure appears to me to be 

 very like M. Fliilippinarxim, A. Ad. 



M. PRUiNOSA, Reeve. PL 41, fig. 215. 



Pale brown, with short, narrow snow-like streaks, rather irreg- 

 ularly descending or striking out from the sutures ; decussately^ 

 engraved with longitudinal and transverse impressed lines. 



Length, -9 inch.

 A doubtful species.

M. of Burias, PhiUpinne^ ; under stones at low Avater ; 



New Caledonia. 

 Var. BoissACi, Montrouzier (fig. 211). 



Has the same sculpture, and diff'ers only in presenting a series 

 of quadrangular chestnut spots, appearing like interrupted longi- 

 tudinal bands : they are the bands of falgetruvi, in fact, but

the angular revolving cost*. Length, 1 inch.
