Very much like Sc. vestalis of Hinds, lately described in the • Zoo- 

 logical Proceedings/ but more elongated, with a larger umbilicus and 

 with the varices near the suture simple, whereas in Sc. vestalis they 

 are acuminated. 



Collected by Mr. Cuming in sandy mud at eight or ten fathoms, 

 at Catanauan, province of Tayabas, isle of Luzon.

 aperturd ovali, postice subangulatd, labio interno vix incrassato et 

 expanso ; umbilico parvo ; colore pallidissime fulvo.
