from the collections of Mr. Cuming, Dr. Gray, Mr. Taylor, Mr. 
Metcalfe, M. Crosse, and M. Lorois, and two are in the British Mu- 
seum. ‘The seven alleged species of which I have not obtained the 
types are three described by Mr. Hinds, which appear either to be 
lost or transferred to other species, and four described by Philippi in 
the ‘ Zeitschrift fiir Malacologie.’ These 214 species I reduce (in my 
monograph of the genus in ‘Conchologia Iconica,’ where all the speci- 
mens are figured) by rejecting 65 as synonyms ; and the number, thus 
reduced to 149, I bring up to 155 by describing six species which 
appear to me to be really new. 
M. Deshayes, in his paper, described 93 species as new ; of these 
I reject 41. The following is a list of the whole 69 which, I submit, 
are merely varieties, or duplicates, of species already described. The 
numbers which follow are those of M. Deshayes’s list.
