HELIX (POM ATI A) ASPERSA Mull. 



By JOHN W. TAYLOR. 



In treating of this species I have again been largely 

 indebted to the kind friends who so obligingly assisted me with 

 the former paper. 



The very numerous cases where I have received the 

 assistance of Mr. C. Ashford, Mr. Butterell, Mr. J. Emmett, 

 Mr. L. E. Emmett, Mrs. Fitzgerald, Miss F. M. Hele, Rev. 

 W. C. Hey, Rev. J. McMurtrie, Mr. Nelson, Mr. Roebuck, Dr. 

 Buchanan White and numbers of other friends, cannot always 

 be expressly indicated, but I am desirous of acknowledging here 

 how greatly I have benefited by the knowledge so freely placed 

 at my disposal. Mr. C. Ashford has, in addition to large stores 

 of miscellaneous information, again placed his knowledge of 

 darts and dart sacs at my service, and Mr. Butterell has again 

 kindly furnished me with slides of the jaw and lingual ribbon.
