and H. Von Meyer, 1848, 1 Band, p. 180, Tab. XXV, fig. 14) has described and figured a valve of Pollicipes 
liasinus : he considers it as one of the great hinder lateral valves—that is, a tergum. This eminent palzon- 
tologist is well acquainted with the cirripedia, and is therefore probably right in his determination ; but Iam 
forced to say that the manner of growth seems to me, if I rightly understand the figure, unlike that of the 
terga in any known Pollicipes. 
Miiller (Aachen, p. 43, Tab. II, fig. 16,) has described Pollicipes ornatissimus ; the valve figured is a 
carina, I believe, of Scalpellum maximum.

The specimens here figured by Mr. Sowerby, were found by Mr. Wetherell in a deep well in the London 
Clay, at Hampstead, together with portions of Scalpellum quadratum. The specimens are in a broken con- 
dition, and have been kindly lent me by Mr. Wetherell: they consist of some fragments of terga, and I 
believe of the basal portion of a scutum, of a carina, and of several latera. The species appears to have 
come near to the Eocene P. reflexus ; but although thinking it distinct, I dare not, considering the imperfect 
state of the scutum, name it. The valves appear to have been much thicker and more rugged than those of 
P. refiecus ; the basal angle of the terga sharper, and the rostral angle of the scutum more abruptly trun- 
eated. The latera are remarkable, and unlike anything which I have seen; they present several shapes ; 
they are all more or less triangular, and their lateral edges are more or less distinctly bordered exteriorly by 
prominent ridges; one has a central exterior ridge, and its basal margin is protuberant ; another has one of 
its sides at right angles to the basal margin, and the other side largely convex. Not having seen the lower 
latera of the P. reflexus, or indeed of any fossil Pollicipes except of P. glaber and unguis, I cannot use 
characters drawn from the latera as diagnostic. The specimens are extremely small.

levium calcarearum instructo ; sex lateralibus multum transverse elongatis ; quatuor termi-

Capitulum with (perhaps) ten valves. Peduncle with ten rows of smooth calcareous 
scales, of which the six lateral rows are much elongated transversely, and the four end 
rows narrow; along the rostral and carinal margins of the peduncle there is a straight 
medial suture, with the scales not intersecting each other.

I owe to the kindness of Mr. Wetherell an examination of this beautiful and unique 
specimen, well described and figured by Mr. G. B. Sowerby, Junr., in the ‘ Annals of
