Synopsis of the known species of Terebra, by Mr. Hinds. 
The genus Terebra, as at present received, contained in the time 
of Linnzus several species, which were then referred to Buccinum. 
Lamarck enumerates twenty-four species ; seven were described in the 
Tankerville Catalogue by Mr. Sowerby in 1825 ; twenty-one by Mr. 
Gray in the Zoological Proceedings for 1834; and a few additional 
are scattered through other publications. The list of M. Deshayes 
assigns the amount of recent species as forty-four, and of fossil as 
sixteen, at the period of its formation. M. Kiener’s Monograph 
contains thirty-five recent species. In the following synopsis con- 
siderable care has been taken to compare the previously described 
species with each other, so as to correct their synonymy, and also in 
collecting their different habitats; for on this point our information 
was most deficient, since the native country of several of the La- 
marckian species was unknown or only vaguely mentioned, and in 
those described in the Zoological Proceedings for 1834, the locality 
of a single species is alone given. As the authority for a habitat 
always increases its value, it is here inserted ; and to those for which 
I am myself responsible, my initial is attached. 
The statistical details stand thus :—Species previously described, 
recent 58, fossil 24; now first described 50—total 132; both recent 
and fossil 8.

’ The sign attached to this and other species is meant to represent that 
they are found both in a recent and fossil state. In practice I have found 
it highly convenient to employ certain signs, and having shown them to 
some who have regarded them as useful, they are here introduced. I have 
expressed a recent shell by the sign +; a fossil shell, |; and one found in 
both conditions, {. And I have found a great advantage in these signs, 
that they are easily converted.
