PUSIA. 195 



T. SEMICOSTATA, Allt Oil. 



Chestnut-brown, blotched with white on the spire. 



Length, -5 inch. 



Habitat unknown. 



The sculpture appears to be different from that of T. tricolor : 

 it is a doubtful species. 



T. COLUMBELLARIA, Scacchi. PI. 51, figs. 641, 653. 



Yellowish to dark chocolate ; revolving striae becoming obso- 

 lete in the middle of the body-whorl ; columella with two plaits.

Mediterranean Sea. 



Referred by some authors to the genus Columbella. The 

 synonyms are T. obsoleta, Phil. ; T. olivoidea, Cantraine ; T. 

 clandestma, Forbes (.fig. 641) ; T. leontocroma, Brusina; T. stria- 

 tella, Calcara; T. Greci, Phil. (fig. 653), a Sicilian fossil. 



Three little Mitras are published by Brusina without figures : 

 M. columbulse, M. striata, and M. typostigma, all from Dal- 

 matia ; they are possibly all referable to this species.
