276 MELVILL AND STANDEN : SHELLS FROM LIFU. 



whorls are sparsely spotted with fulvous ; in the last whorl the 

 spots again occur towards the middle, but are contiguous to,

 specimens. To Mr. S. Pace our thanks are due, he having 

 given advice concerning the Columbellidos of this collection, 

 and as a very slight return we would venture to associate his 

 name with not the least elegant of that genus to which he is 

 devoting so much laborious study.
