'ALERT.' 67 The examples before me differ from the description of Edwards and Lucas, in the third joint of the legs not being armed with any prominent spines, and in this joint in the ambulatory legs being less dilated and compressed; but this may probably be due to the greater age of Dr. Coppinger's specimens. The carapace is densely pubescent; the chelae naked, and of a bright rose-colour. Length of largest individual about 1-J inch. Two Californian species described with doubt as belonging to this genus by Mr. Lockington, Pr. Cal. Ac. Sci. vii. pp. 66, 67 (1876), under the names of Pisoides ? celatus and P.? tumidus, belong, as learn from a MS. note of the author, to Microphrys-the former being identical with Microphrys platysoma, as noted by Streets and Kingsley. CANCER PLEBEJUS. Cancer plebejus, Pdppig, Arch. f. Naturg. p. 134 (1836); A. M.Edwards, Nouv. Arch. Mus. Hist. Nat. i. p. 188 (1865). A young male individual was taken in Picton Channel, at a depth of 6 fathoms, on a bottom of sand. Two females were dredged at Talcahuano. CANCER EDWARDSI. Cancer edwardsii, Bell, Trans. Zool. Soc. i. p. 338, pi. xliv. (1835); A. M.-Edw. N. Arch. Mus. H. N. i. p. 123 (1865) ; Cunningham, I.e. p. 491 (1871). Platycarcinus edwardsii, Gay, Hist, de Chile, iii. p. 144 (1849). A young male was taken at Talcahuano, in which the coloration is of the normal type. CANCER EDWARDSI, var. ANNULIPES, n. A young male was found on the beach in Trinidad Channel. In its convex carapace, and in the form of the teeth of the antero-lateral margins and of the anterior legs, this species agrees well with normal specimens of the Chilian C. edwardsii. It differs, however, remarkably in the coloration, which is very well preserved in the specimen (a dried one). The prevailing colour is light yellow, varied with blotches of dark purplish brown ; and the joints of the legs are regularly annulated with broad bands of the same colour. Length about 2 inches, breadth 3. PARAXANTHUS HIRTIPES. Paraxanthus hirtipes, M.-Edw. & Lucas, in d'Orbigny's Voy. Amer. m6rid. vi. Crust, p. 18(1843); Nicolet, in Gay's Hist, de Chile, iii. p. 141 (1849). A female is in the collection from Talcahuano. I may take this opportunity of noting that two young specimens received from Mr. Lockington, and labelled by him " Xanthodes hemphil^m," appear to belong to this species. Mr. Lockington has since identified the types of X. hemphilliana with Lophoxanthus 5* |
