My Cabinet. 

 Diam. 1.3, Length 2.3 inches. 



Remarks. — I am under obligations to W. Wood for this beautiful Bulimus, 

 and many fine shells herein described, from the Philippine Islands. They 

 were sent to me from Manilla, his present residence. This species is very 

 remarkable in the contrast of the brown above and green below the ca- 

 rina in the middle of the whorl. Within, it is very white, which contrasts

 the inferior part of the whorl, the substance of the shell is white. The base of 

 the spire is dark brown.
