 Eburna Pacifica. Swainso?i, Appendix' to Bligh Cat. p. 6. lot 904. 

 Eburna lutosa? Enci/. Meth. pi. 401. y, 4. 



A DELICATE and rather uncommon shell: first defined in 

 the Appendix I subjoined to the Catalogue of the Bligh 

 collection, dispersed by auction last spring. Mrs. Mawe 

 informs me she has received this, along with other shells, 

 from the Pacific Ocean. 



A species at once distinguished by the entire suture and 

 narrow-pointed spire ; the inner lip is very thick, with a 

 longitudinal sulcation near the umbilicus. 



Whether this is the shell represented in the Enci/. Mtth. 

 at pi. 401, y. 4, admits of doubt : a short description would 

 have explained the characters, but not one word is said 

 about it. I have already adverted to this novel mode of 

 creating species at pi. 31. If authors will not be at the 

 trouble of defining new species, they have no right to expect 

 their names should be adopted by subsequent and more 

 laborious writers, to whom they leave the more scientific 

 task, of defining characters and collating synonyms,
