Scania: all these northern specimens have been of the greatest use to me in illustrating the British species. Having applied to Professor W. Dunker of Cassel, for some of the species described by various German authors, he not only sent me many specimens out of his own collection, but procured from Messrs. Roemer, Koch, and Philippi, other specimens of great value; and to these most distinguished naturalists I beg to return my very sincere thanks. Lastly, I may be permitted to state, that I

details are given. The P. radiatus of the same author, of the lower greensand (Pl. XI, fig. 6), is unknown to me; the tergum figured is like that of S. arcuatum; the upper valve, if a scutum, is very remarkable. The name Pollicipes radiatus has been a favorite with authors; there is a tertiary species so called, but not described in 'Müller's Jahrbuch,' 1835. Koch and Dunker, also, (Norddeutsch. Oolithgebildes, 1837,) have given this name to a tergum found, according to Roemer, in the Hilsthon or

Cirripedia. To Mr. Conrad I am likewise indebted for information and assistance. Both the celebrated Professors, Milne Edwards and Müller, have lent me, from the great public collections under their charge, specimens which I should not otherwise have seen. To Professor W. Dunker, of Cassel, I am indebted for the examination of his whole collection. I have, in a former publication, expressed my thanks to Professor Steenstrup, but I must be permitted here to repeat them, for a truly valuable

, Germany.) Messrs. Koch and Dunker have given a full and detailed account of this species, together with truly excellent figures, and I have nothing to add to their remarks, but will re-describe, for the sake of uniformity, the valves of this species, which, through the kindness of Professor Steenstrup and Professor Dunker, I have examined. The valves are slightly worn. The figures given in tab. III are not, I think, so good as most of the others. Scuta (Tab. III, fig. 3, b, c) moderately convex

. Dunker and Roemer. I have had far more difficulty in making up my mind regarding this the commonest cretaceous species, than with all the other fossil pedunculated cirripedes. From reasons previously stated, I have in this genus, when only separate valves have been found, taken the carina as typical. Comparing ordinary specimens of the carina of Scalpellum maximum and var. sulcatum, such as those figured in the 'Mineral Conchology,' I should certainly have considered them quite distinct, had not an

covered by a lateral projection of the central portion: a tolerably distinct ridge runs from the apex to the baso-lateral angle. Amongst the several specimens from Hanover sent me by Drs. Dunker and Roemer, the scuta all belong to the First variety. I believe all these differences in the scuta of the three varieties ensue partly from the varying acumination of the upper part, and consequently of the extent to which the apex projected freely, but chiefly from the degree to which the upper part
