ACHATINA MONILE. 
(Lot 642 and 967). 
A. (div. 2.) testd subtilissimée reticulatd, albente, strigis undulatis 
fasciisque transversis castaneo-maculatis ornatd ; anfractu basalt 
sub-ventricosd ; spire product anfractibus 2 ultimis approxi- 
matis ; apice papilloso ; basi vix integra. 
Shell very finely reticulated, whitish, with waved stripes, and 
transverse bands of chesnut spots; basal volution, sub-ven- 
tricose; spire produced, the two last volutions close, and the 
tip papillary ; base nearly entire. 
Two fine specimens of this shell are in the collection; two 
others I have previously examined, and, as they all present 
the same characters, I cannot but consider them as a 
distinct and decided species, from the Bulla zebra of Martini 
(vol. 9. f. 1015 and 6,) and the Bulimus undatus of Bru- 
gulere.

LirtLx praise can be bestowed on Bruguiere for the wide 
latitude he has given to the characters of his genus Budimus, 
which is nearly as comprehensive as the Linnean Heli; 
and this species of a genus of shells, introduced by Lamarck 
into the right place in the system, I propose to distinguish
