CRUSTACEA. 63 



XENOPHTHALMUS White. 



XEROPHTHALMUS PINNOTHERC-IDES, White. (Tab. XII. Eig. 3.) 



Thorace punctulato, sulcis duobus longitudinalibus ab oculis porrectis, lateribus antice ciliatis. 



Pedibus articulis ciliatis. 



Hab. Insulas Philippinas. 



Xenophthalmm pinnotheroides, White, Annals and Mag. Nat. Hist. 



Carapace with the sides, in front, having a sharp ciliated edge ; carapace punctured ; 

 two slight waved longitudinal grooves, one extending from each eye over the back of the 

 carapace ; most of the joints of the legs ciliated. 



Hab. Philippine Islands. 



We figure this curious genus on account of our being able to give a coloured repre- 

 sentation from a drawing made from life in the Eastern Seas. A. A. 



RHABDOSOMA, Adams 8f White. 

 Oxycephalous, M. Edwards. 



We regret that the state of the only specimen in the British Museum is such that we 

 cannot give the generic character with that detail which we should wish. It is founded on 

 the third species of Professor Milne Edwards, indeed Mr. White has the authority of that 

 eminent Crustaceologist that it is his very species : it is so different from the Oxyceplialus 

 piscator, M.Edwards (Crust. III. p. 100. t. 30. f. 10), that we have traced the figure of 

 O.piscator, and added it below that of the 0. armatus, to show the difference. Some day 

 it may be proved to be a sexual character, when of course our name will sink, but as yet we 

 know of no such discrepancies in the sexes of these Crustacea. 



The head is as long as the rest of the body, and ends in a very long beak ; from the 

 state of our specimen we cannot describe this, but indicate it on the plate from a drawing 

 made at the time of capture. The immense length of the body and the beak would 

 sufficiently mark this generic form. The first two pairs of legs are shown in the figure, which 

 must serve till we can procure further specimens, when we hope to give ample details of this 

 very singular crustaceans and to analyse its characters at length. It forms a singularly 

 interesting link between the Amphipoda and Lcemodipoda, uniting, as it were, the two ; we 

 should like to have this form examined particularly by Prof. M. Edwards or Dr. Kroyer. 



EHAPDOSOMA AEMATUM, Adams Sf White. (Tab. XIII. Fig. 7.) 

 Oxycephalous armatus, M. Edw. Crust. III. p. 101. pi. 30. f. 10, copied. (Tab. XIII. Fig. 8.) 

 The specimen described by Professor Milne Edwards was found by MM. Quoy and 

 Gaimard in the ocean between Amboina and Van Dieman's Land, and is now in the Paris 

 Museum. Ours was taken during a calm, floating on the surface of the South Atlantic 

 Ocean.
