15 millim.), without exact locality (II. M.S. ' Herald'), the carapace 

 has three brilliant patches of red — one on either sido of the middle 

 line on the frontal region, and one on the cardiac region reaching 

 to the posterior margin. No trace of this coloration appears in the 

 specimen from Darros Island. Imt in other particulars they are 

 closely alike. This species, although rare, has a wide Oriental dis- 

 tribution. Stimpson's types were from the island of Ousima, and 

 A. M.-Edwards records it from New Caledonia ; Ililgendorf (though 

 doubtfully) from Mozambique. By Kossmann (t,. c. p. 47) this 

 species, as also T. crenata, is united with T. prymna, Herbst: 

 possibly therefore it occurs also on the coasts of the lied Sea, but 

 there is nothing to show whether Kossmann had among the speci- 

 mens he refers to T. prymna any examples truly referable to 

 T. picta, Stimpson. 



52. Lissocarcinus orbicularis, Dana. 



A small male from the Seychelles, 4-12 fms. (No. 194), seems to 

 be referable to this species ; it has the carapace very prettily 

 marked with circular spots of a dusky purplish colour with darker 

 borders. Specimens are in the British-Museum collection from the 

 Samoa Islands (Rev. S. J. Whitmee) and Suwarrow Island (21. 

 Hurt). In these specimens, as in the one figured by Dana from the 

 Fijis, the purplish markings usually predominate, so as sometimes 

 nearly to cover the carapace. 



Of the type of the genus (L. polybioides, Ad. & White), which has 

 a more elongated carapace with more prominent front and more dis- 

 tinctly developed lateral frontal lobes, there are, besides the original 

 specimens from Borneo, two examples from Ceylon (E. W. H. 

 Holdsworth) in tho Museum collection. 



53. Gelasimus annulipes, M.-Edw. 



A series of specimens was obtained on the beach at Mahe Island 

 (No. 19(3). 



To the localities (whence the Museum possesses specimens) men- 

 tioned in 1879, in my Report on the Crustacea of the Transit-of- 

 Venus Expedition, the following are to be added : — Kiver Zambesi 

 (H. Waghorn) ; Port Natal, D'Urban Bay (Alfred E. Craven); 

 Celebes (H.M.S. ' Samarang ') ; Batjan (coll. Br. Bleeker) ; and 

 Timor Laut (H. 0. Forbes), received together with G. telragonum 

 and G. vocans. 



Kossmann (t. e. p. 53) records a variety (albimanus) from the lied 

 Sea, which is apparently scarcely distinguishable from the typical 

 form of the species. 



54. Gelasimus dussumieri, M.-Edw. 



A specimen obtained at Mahe' Island with the preceding species 

 is referred here, although with some hesitation. G. dussumieri has 

 been hitherto a desideratum in tho Museum collection.
