1900.] FROM THE SOUTH PACIFIC. 571 



The classification followed is that of Ortniann, in Bronn's 

 ' Thier-reich.' In one or two points, however, slight deviations 

 from this scheme will be found. The three tribes of Crabs seem 

 still to have enough in common to justify us in keeping the old 

 name of Brachyura in its full extent; and I have accordingly 

 adopted de Haan's term Brachygnatha for the groups included by 

 Ortmann in his restricted Brachyura. Following the latter writer's 

 suggestion as to the inclusion of Thia Leach in the Atelecyclidse, 

 it is proposed to transfer Alcock's Thiinse * bodily to that family, 

 and Kraussia Dana is accordingly classed here. Lastly, under the 

 heading Portunidse, there will be found certain suggestions for an 

 amplification of Ortmann's classification, notably the establishment 

 of a new subfamily for the genus Goniocaphyra de Man. 



Major Alcock's admirable series of papers on the Indian Crabs 2 , 

 containing as they do diagnoses and bibliographies for a large 

 number of the species included in the present collection, make it 

 unnecessary to give more than a very short list of references for 

 these species. For the sake of convenience, however, a reference to 

 the original description and, when possible, to a figure, is given, 

 together with one to Major Alcock's work. In the case of species 

 mentioned also in Whitelegge's report on the Funafuti Crustacea, 

 I have included a reference to that writer's paper.

One male from Eotuma, bearing an ascidian. The tooth at the 

 side of the carapace is rather farther back than is indicated in 

 de Man's figure. The locality of this species has hitherto been 

 unknown.
