Differs from 2\ calcadensis, with whirii tlie species has been 

 confused, in having one whorl less, and being much smaller, with 

 proportionately shorter whorls ; the sculpture is less close aud 

 distinct, the colour whitish instead of golden brown, the basal 

 keel less developed, and its opening is in the same plane as the 

 aperture, instead of being turned downwards. From T. costuhtta 

 it is chiefly distinguished by its much liner sculpture and bv the 

 characters of the basal keel. 



The accompanying figures have been drawn from a specimen in 

 the general collection of the British Museum. Its measurements 

 are: alt. 13';'3 ; major diam. 5 unn. The species has not before 

 been illustrated.
