" This remarkable shell," says Reeve, " is curiously inter- 

 mediate in its generic characters between Strombus and Ptero- 

 cera. In detail of pattern and sculpture it resembles S. laciniatus, 

 but there is a large central oblique tubercle on the back, and the 

 lip is thickened into two very large obtuse oblong tubercles, the 

 upper part being produced into two decided Pterocera claws.
