LEUDUGERIA. 



539 



Valve semi-lunate, finely striate, with margins furnished with 

 small spines, from which arise somewhat more robust striae. Striae 

 radiating, finely punctate, only extending to the centre of the 

 valve, which is smooth. Girdle face cuneate. 



In the text will be found (fig. 286) from one of my photographs, P. 

 Hardmaniana Grev., with the observation that the robust striae have been 

 exaggerated in the drawing. This species is found in China.

 Girdle face straight, showing on one of its faces an inflexion at the
