4 BR. W. T. CALMAN ON A COLLECTION OF 



Carpilitjs convkxus (Forsk.). 



Carpilius convexus, H. Milne-Edwards, Hist. Nat. Crust, i. p. 382, pi. xvi. figs. 9-10; Alcock, 



Jouru. Asiatic Soc. Bengal, Ixvii. (2) p. 80 (1898). 

 Three females and two males. One labelled " Found within hollow in Tubipora." 

 .Locality. " Mer." 



Carpilodes sp. 



A number of very small specimens belonging to this genus do not agree satisfactorily 

 with any of the described species, but in the absence of a larger series for comparison I 

 do not venture to describe them as new. They are identical with certain small specimens 

 in the British Museum determined as C. rugatus, Latr., but differ from larger specimens 

 of that species and from the figure given by A. Milne-Edwards (N. Arch. Mus. Paris, i. 

 pi. xii. figs. 3, 3 a-h) in the fact that the lobulations on the surface of the carapace, 

 and especially on the branchial regions, are more numerous and do not have the 

 regularly transverse direction so marked in C. rugatus. 



The C. cariosm of Alcock (Journ. Asiatic Soc. Bengal, Ixvii. (2) 1898, p. 86, and 

 Illustr. Zool. ' Investigator,' Crust, pl. xxxvi. fig. 7, 1899) * resembles our specimens 

 rather closely ; but in that species the carapace is not quite so broad, the antero-lateral 

 borders less convex, and the lobules on the lateral regions of the carapace are arranged 

 in a slightly different manner. 



Locality. "Murray Island, 15-30 fms."

The synonymy of this species and of the genus of which it is the type give striking 

 evidence of the intangible nature of the characters on which we are forced to rely in the 

 classification of the Xanthoid crabs. As defined by Dana, Liomera is stated to resemble 

 Carjiilius in the disposition of the antennae (that is to say, the basal anteunal joint enters 

 into the inner orbital hiatus), and the genus is separated from Carinlodes only by the 

 fact that the fingers are said to be sharp-pointed instead of spoon-shaped at the tip.
