Stat. 207. Buton-strait. 148 M. Grey mud. 2 Spec. 



Tryon (1. c.) considers this species to be a variety of B. subgra7tosa ; I find too important 

 differences in shape, sculpture, especially of the varices and in the canal, to share his opinion.

 Stat. 172. Between Gisser and Ceram-Laut. 18 M. Coral- and Lithothamnion-bottom. i Spec. 



The specimen from Stat. 172 is young, and has the aperture not developed, that from 

 Stat. 66 though small, has well-developed apertural margins, which are dark purple, with lighter 

 patches, and resembles in colour of the aperture. Reeve's Ranella venustula (I.e. fig. 37) but does 

 not agree with the description of that species. It resembles also the figures of R. Pauhicciafia 

 Tapp. Can. (Ann. Soc. Mai. Belg. Vol. XV, fasc. I, PL 2, fig. 16, 17), but it is not so dark and 

 has a higher spire. The identification of small specimens in this group remains somewhat 

 uncertain. Tryon considers this species to be a variety of B. cruentata Sow.
