CRTJSTACEA. 213 



females in the second collection, the one obtained at Friday Island, 

 Torres Straits, 10 fms. (No. 158), and the other in the Arafura Sea, 

 32-30 fms. (No. 160). These specimens are both of very small 

 size, one with ova measuring only 2^ lines (5 millim.) in length. 

 They differ from M. A. Milne-Edwards's description and figure in 

 being (in spirit) of a uniform ashy-grey colour, and in having the' 

 surface of the carapace very uneven, well-marked depressions ex- 

 isting at the back of the cardiac region and in front of each branchial 

 region ; the surface of the body, viewed under the microscope, is 

 minutely and very closely granulated, but appears smooth to the 

 naked eye. 



Milnc-Edwards's examples are from New Caledonia and Lifu, 

 and are much larger, the carapace measuring over half an inch 

 (13 millim.) in length. The inequalities of the carapace observable 

 in our specimens may very probably disappear as the animal in- 

 creases in size ; therefore I do not regard the Australian specimens 

 as belonging to a distinct species. 



Ci/clo.vanthus punctatus, Haswell (Catalogue, p. 50), from the 

 Paramatta Itiver, seems to be a very distinct form, to judge from 

 the brief diagnosis*.

44. Carpilodes venosus, M.-Echv. 



A female from Port Molle (No. 95), obtained on the beach, belongs 

 here. 



This specimen (preserved in spirit) is of a deep purplish-red hue, 

 and has the sulci defining the areolets of the carapace very distinctly 

 defined, and altogether corresponding in arrangement with the 

 same sulci in De Haan's figure of his C. obtusus, which is, I believe, 

 a mere variety of this species. The length of this example is a 

 little over 7 lines (15 millim.), and its greatest width nearly 1 inch 

 (25 millim.). 



In a larger female example from the Japanese seas, presented to 

 the British Museum by Capt. H. C. St. John, B.N., and received 

 since the publication of my report on the Podophthalmia of his 

 collection — length of carapace over 10 lines (22 millim.), width 

 1 in. 5 lines (36 millim.) — the colour (in spirit) is a lighter orange- 

 red, and several of the sulci of the carapace less distinctly defined 

 or partially obliterated ; this is no doubt due to the greater age of 

 the specimen. 



Stimpsont mentions the occurrence of C. venosus (as Liomera 

 obtusa) at Ousima Island in the Japanese seas ; and there is a 

 specimen in the British-Museum collection from the Philippine 

 Islands, Corregidor {Cuming), designated G. venosus, and others from 

 Sir C. Hardy's Island, dredged in 11 fms. {J. B. Juices), &c. Its 

 range extends from the Mauritius to New Caledonia. 



* It may be useful here to mention that Panopeus acutidens, Haswell {t. c. 

 p. 51, pi. i. fig. 2), is scarcely to be regarded as distinct from Epixanthus den- 

 tatus (Panopetis dentatus, Ad. & White), of which there are authentic specimens 

 in the British-Museum collection.
