* So in first printed hst and in two MSS. ; but in Check-List of Dec. 9, Ph. Troos- 

 iiana, Lea, is assigned to the West, instead of this species. The MSS. are probably 

 correct. 



I Non Bidinus, Sby., oHm,-=Bulimus, auct. However clearly Bidinus, Binn., may be 

 right according to the antiquaries, it is far too like Bulimus, which has taken complete 

 possession of the entire malacological world, to be allowed a resurrection in the same 

 order. Surely burial for a given number of years ought to be allowed as evidence of 

 death, especially if the infant-name scarcely even breathed the air of use, and its resur- 

 rection would breed malaria among terms thriving in the vigorous manhood of universal 

 acceptance. 



§ It is quite possible that this may prove a very finely grown specimen of P. lentus. Dr. 

 Kennerley's shells are intermediate. 



II Thus in Check -List, Dec. 9th. In. that of May 4th, it appears as Planorhis N. ; in the 

 MS. list a& Carinijera,
