of viewing Mr. Barlee’s typical tablets of this variety of the 
Chem. acuta. 
We need only say of the C. plicata and C. unidentata, that 
they are old Montaguan species; the two latter animals are 
described by us. 
The C. glabrata? of Miuhlfeldt, said to be a production of 
one of the isles of the Ultima Thule, is quite unknown to 
us*, The animals of the C. acuta, C. conoidea, and C. spi- 
ralis are fully mentioned; their shells are admitted as 
genuine indigena by every one. The Chem. acuta was dis- 
covered by us many years since at Exmouth, but at the time 
we neglected to publish notes on the hard parts; it is curious 
that after a lapse of thirty years we should be the first to 
rediscover and describe the animal. 
The new Chemnitzia Barleei, as yet only known as a 
northern production, is the discovery of that excellent and 
indefatigable malacologist whose name it bears, and from 
specimens from himself has first been ushered into notice 
by ourselves as an undoubted member of this singularly 
difficult genus; and it affords, in the misconceptions that 
have attached to it, a plain proof of the correctness of this 
observation. 
This species has been introduced and figured as the Rissoa 
eximia, and subsequently in the Appendix of the ‘ British 
Mollusca’ as Chem. eximia. Surely the specific title of 
“ Barleei,” the discoverer, ought, in this case, to have pre- 
cedence over even a prior one, applied erroneously. 
After the reforms we have submitted, the British list will 
exhibit some attenuation ; but a still numerous and a sounder 
family will testify the importance of this truly British group, 
which far outnumbers the discoveries of any other country in 
respect of this peculiar and very interesting genus. We think 
that the expurgation that has been made will bring the ac- 
quirement and identity of our indigenous species within the 
reach of the naturalist in this particular line of science. 
* Since this remark we find that British representatives of this obscure 
species are only worn C. pallida.
