Locality. Sconce (Edwards). 
After my plate had been arranged I ascertained that several species of this genus, 
belonging to the Upper Eocene of the Isle of Wight, which had not been figured by Mr. 
Edwards, were in his cabinet, and I have been here able to introduce one of these as above 
referred to, and as Mr. Edwards had probably given to it a careful examination, and 
satisfied himself that it was a new species, I have much pleasure in adopting the name 
he has proposed for it. 
It slightly resembles a shell from the Lower Tertiaries of France, H. Hederti, 
Deshayes (‘ An. sans Vert. du Bas. de Par.,’ tom. ii, p. 813, pl. lu, figs. 5—7); but, 
judging from the figure, it appears to possess several differences. M. Deshayes also figured 
and described a shell (‘ Dese. de Coq. Foss. des Env. de Par.,’ p. 55, pl. vi, fig. 3), to which 
he gave the name of 7. dubia, from near Versailles, and he gave for it also the locality 
of the Isle of Wight; but in his second work, at p. 826, he has doubted the propriety of 
that statement, and thinks that his shell is an incomplete specimen of /7. J/oraguesi, but the 
figure of this (dvza) more resembles our shell than does any other. Mr. Edwards, he 
says, has denied the presence of 7. dudia in our English beds, and I have not the means 
of making a comparison. 
I fear that some of these fossil /e/ices must be carefully compared with the specimens 
of the foreign species before a perfect identity or non-identity can be relied on ; and this 
I am not able to do. M. Deshayes has not given as a synonym any //eliz from the 
English 'Tertiaries.
