The costellee are not tlattened, as in P. idlida, but dis- 

 tant and prominent.

The nodulous Pykamidella. Shell conically sub- 

 ovate, white, wiili reddish spots in transverse rows, 

 about ten whorls angulated above, with plaits pro- 

 duced into angular nodules at the angles below, mi- 

 nutely pitted, aperture leng-thcned, pyriform, colu-

 tliick, emarginate posteriorly.

11(d). Philippines ; Cuming. 



The lower part of the whorls is curiously punctured 

 with little round pits, forming the surface into a sort of 

 network between them, wliile the upper angle is orna- 

 mented by pliciform nodules produced into angles.

 lightlv banded with reddish-brown beneath, whorls 

 rather convex, ribbed, angtdated at the suture, ribs 

 rounded, straight, narrow, rather distant, smooth, in- 

 terstices spirally ridged, last whorl bent forwards and

 in the lower whorls, are rather distant and the interstices 

 spirally ribbed.
