This species also occurs in the Loyalty Islands, for specimens of it 

 from Lifu were given to me under the name of (Jitlmrd stn'ateUii Smith. 

 A different, though related, species has lately been figured*'- under this 

 name. Possibly mine is the species which Bouge and Dautzenberg^^ 

 doubtfully record from Lifu as Mnngelia iiwpta Smith. 



This dainty little shell is appropriately named after the lady whose 

 drawings embellish this memoir.
