534 COLLECTIONS FROM THE WESTERN INDIAN OCEAN. 



dentated, and carapace and chelipedcs less distinctly granulated ; in 

 other particulars, however, they closely resemble the other examples 

 in the British- Museum collection. In all the specimens I have 

 examined there is a very large subbasal tooth or lobe on the inner 

 margin of the mobile finger of the hand of the larger chelipede. 



Dana records this species from the Kingamill and Society Islands, 

 and Stiinpson from Loo Choo. It is evidently a widely distributed 

 Oriental form. 



Since the designations Rwppellia and Eudora have both been pre- 

 occupied in zoology (the former by Wiedemann, in 1830, for a genus 

 of dipterous insects, and the latter by Peron and Lesueur, in 1809, 

 for a genus of Acalephce), I have slightly modified the former name, 

 which has so long been used by carcinologists for this species of 

 crab. 



35. Ozius (Epixantlms) frontalis, M.-Edw. 



Mahe Island, beach (No. 106) ; two males — one adult, the other 

 very small. 



Specimens are in the British-Museum collection from Madagascar, 

 Tamatave (Rev. Deans Cowan); Nicol Bay, N.AV. Australia (M. du 

 Boulay); Fiji Islands, Ovalau (H.M.S. 'Herald'); Samoa Islands 

 (Rev. S. J. Wliitmee). 



The genus Epixantlms can scarcely, I think, be regarded as gene- 

 rically distinct from Ozius ; but the name may be conveniently used 

 as a Bubgeneric designation for the species with broader, more 

 depressed, and flattened carapace (cf. A. M. -Edwards, Nouv. Archiv. 

 Mus. Hist. Nat. ix. p. 240, 1873). 



Of the species designated by Adams and AYhite Panopev.s formio *, 

 there are two specimens in the Museum collection. The smaller, from 

 Ligitan, is not to be distinguished from normal specimens of 0. fron- 

 talis. The larger, which is an adult male, and is apparently the 

 specimen figured, and therefore the type, has the carapace some- 

 what narrower and more convex, and the first tooth of the antero- 

 lateral margin shorter and more distinctly separated by a notch 

 from the outer margin of the orbit, which is also notched. On 

 account of this latter character the species, as represented by this 

 specimen, must, I think, be retained, together with Eptocanihu* 

 dentatus (Ad. & White), in the genus (or subgenus) Efeteropanopel 

 in which Stiinpson long ago included it (Proc. Acad. Nat. Sci. 

 Philad. p. 35, 1858). 



36. Eriphia lsevimanus (M.-Edw.) 



Two females from the beach at Darros Island (ISo. 200), and a 

 small male from the Glorioso Islands (No. 220), have been retained 

 for the Collection. 



The series in the British Museum includes specimens from the 

 Mauritius (Lady F. Cole); Madagascar (l)r. J. E. Gray) and Tama- 



* Zoology of ' Samarang,' Crustacea, p. 4Jj, pi. ix. fig. 1 (1848).
