THE ANNALS Aim MAGAZINE OF NATURAL HISTORY. [THIRD SERIES.] No. 46. OCTOBER 1861. XXIX. — Contributions to British Carcinology. — I. Characters of undescribed Podophthalmia and Entomostraca. By the Rev. Alfred Merle Normax, M.A. [Plates XIII. & XIV.] Under the above title I propose to publish, from time to time, notes upon our rarer Crustacea, together with descriptions of sucli new species as may come into my hands. I regret to learn from Mr. Van Voorst that there is no prospect at present of a new edition or supplement to Bell's ' History of British Crus-tacea' being published; may I be allowed, however, through this channel, to express a hope that Dr. Baird may be induced to prepare a Supplement to his admirable * Monograph of British Entomostraca.' Ample material is iu existence ; and such por-tion of it as is in my own collection would be most gladly placed in his abler hands for description, if such a supplement were undertaken. Subclass PODOPHTHALMIA. Fam. PaguridsB. Pagurus ferrvyineus, n. sp. PI. XIII. figs. 1-3. Pedes chelati ciliati, Iceves, neque spiniferi ncqae gramilati (praeter quod marge carpi interior spinosulus est) ; niargo brachii dextri interior setarum scopas gorens.

The carapace in this species is somewhat depressed anteriorly, with the margin not i-ostrate and scarcely flexuous. The long and slender eye-stalks reach to the middle of the last basal joint of the external antenna, and to about one-third the length of the last joint of the peduncle of the interior antennae. The first pair of feet, which are very unequal, are clothed with fine silky hairs. Ann. S^ Maj. N. Hist. Ser. 3. VoLyuu 18
