 Pleiirotoiiia nivea Phillipi. 



Astheiiotohia is founded on a Miocene fossil, Pleurotoma hasteroti 

 Desmoulins,^ which is co-generic, as Jousseaume has explained, witli 

 certain recent Indo-Pacific shells. It appeais to me to be nearh- related 

 to Tnrrls, with which spiral ridges deep within the throat and a smooth 

 mucronate apex associate it. Fi'om Tarn's it differs by smaller size, bent 

 columella, very short and upturned canal, a widely gaping instead of a 

 linear notch, aud b}^ the radial sculpture. The operculum in a specimen 

 of A. iiicea Philippi, di-edged at Karachi, and kindly given to me by Dr. 

 J. C. Melvill, is oblong with a subtei'minal nucleus (PI. xlii., tig. 4). 



From the Aueti'alian Tertiary, Professor Tate^" has noted Astlieimfoma
