564 OBSERVATIONS ON SOME t^lPECIES OF 
XL VIII. — Observations on some Species of the 
Genus Vermiculum of Montagu. 
By the Rev. John Fleming, D. D. F. R. S. E. 
M. W.S. &c. Minister of Flisk. 
{Read 5th April 1823.) 
In the " Testacca Britannica,"' the iate Mr Montagu, 
in the first section of his genus Vermiculum, has given a 
description of five shells, which now belong to the more 
recent genus Miliola. These descriptions, however, are 
scarcely sufficient to enable the young conchologist to iden- 
tify the species, even when assisted by the figures which 
he has added, or those of Walkee, in the " Testacea 
minuta rariora," to which he has referred. In order to 
establish satisfactory specific characters, the permanent 
conditions of the mouth must be attended to, rather than 
the variable forms of the chambers. Under this impression, 
I shall here give the distinguishing marks of four species, 
accompanied by figures of their appearance when magni- 
fied. 
1. V. intortum. Test. Brit. 520. Mouth compressed, 
with a simple tooth attached to the side next the body.
