1881.] THE SURVEY OF H. M.S. 'alert.* 67 



The examples before me differ from the desciiptioii of Edwards 

 and Lucas, in the third joint of the legs not being armed with 

 any prominent spines, and in liiis joint in the ambulatory legs 

 being less dilated and comin-essed ; 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 oflargest individual about 1^ inch. 



Two Californian species described with doubt as belonging to this 

 genus by Mr. Lockington, Pr. Cal. Ac. Sci. vii. pp. 6ti, 6/ (187(3), 

 under the names of Fisoides ? celatus and P.I tumidus, belong, as I 

 learn from a MS. note of the author, to Microjihrys — the former 

 being identical with Microphrys plaiysoma, as noted by Streets and 

 Kingsley. 



Cancer plebejus.

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.

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, reniarkabl y 

 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 regu- 

 larly annulated with broad bands of the same colour. Length 

 about 2 inches, breadth 3. 



Paraxanthus hirtipes.

 Amer. merid. 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 

 hemphilliana," appear to belong to this species. Mr. Lockington 

 has since identified the types of X. hemphilliana with Lophoxanthus
