Left tergum, Paratype (described, p. 58) [2151b] 
2 Carinse, 4 5 Paratypes (described, p. 58) [2152f, 2152g] 
Holotype . — I here select as holotype the scutum represented 
by figs. 7a, b, registered [2151], 
3. Pollicipes striatus Darwin. 0 
Under this species Darwin says (op. cit., p. 71) — “ My 
materials consist of two scuta, of which one is young; and of 
some terga and a carina which I provisionally here describe.” 
In the Fitch Collection there are two left-hand scuta of 
this species, one being a young example. The large specimen, 
since it has its rostral angle broken as indicated in the figure 
(5c), can be readily identified as the valve there figured in a 
reversed position, and the smaller specimen is no doubt the 
young valve mentioned by Darwin.

Holotype . — I here select as holotype the scutum repre- 
sented by figure 5c, registered [2154], 
4. Scalpellum fossula Darwin. 
Under this species Darwin says (op. cit., p. 24) — “ My 
materials consist of two specimens, belonging to Mr. Fitch, 
4. Darwin (op. cit., p. 58) said that these two carinae were identical 
with the carina figured by J. de C. Sowerby (Min. Conch., 1829, Vol. 
VI., p. 221, pi. 606, fig. 7) as a Cotype of his Pollicipes sulcatus. This 
valve is now in the British Museum (Natural History), registered 
I. 13656. 
5. A carina and a left tergum were also described by Darwin with 
the above scuta as belonging to P. striatus. The carina, which came 
from the Chalk of Kent, was in the collection of the late Mr. Tennant, 
but its whereabouts is not now known. The tergum, which is one of 
the cotypes of J. de C. Sowerby’s P. sulcatus (Min. Conch., 1829, 
Vol. VI., p.221, pi. 606, fig. 1) is now in the British Museum (Natural 
History), registered I. 13662.
