CErSTACEA. 655 



4. Birgus latro (Linn.). 



Du Lise Island, Grlorioso Group ; beach (an adult female). 



Specimens are in the British-Museum collection from the Mauri- 

 tius (Lady F. Cole), Malayasian seas (Dr. P. Bleeker's coll.), and 

 Fiji Islands, Nairai (H.M.S. ' Herald '), besides others from the 

 'Samarang' and 'Herald' collections without special indication of 

 locality. 



5. Coenobita perlata, M.-Edw. 



Eagle and African Island, beach (No. 210). Five males are 

 referred to this species, mostly inhabiting shells of the genus 

 Dolium. 



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

 In this species there is usually an oblique series of somewhat more 

 elongated tubercles on the upper surface of the palm, occupying the 

 place of the ' series of oblique ridges in 0. rugosa. The basal 

 joint of the right fifth ambulatory leg is in the adult male fur- 

 nished with an elongated curved styliform lobe, as noted by De 

 Haan ; this does not exist in a small male from Batjan (coll. Dr. 

 BleeJcer) which I have designated O. perlata var. ? affinis, and which 

 may belong to a distinct species. 



6. Pagurus punctulatus, M.-Edw. 



' Darros Island, beach (No. 199) j a small exanjple in a shell of 

 Valuta geographica (L.). 



Specimens of this very common species are in the Museum col- 

 lection from the Mauritius (Old Collection); Rodriguez (G. Oullivery, 

 Seychelles (Dr. E.' P. Wright); Madagascar (Dr. J. E. Gray); 

 Celebes, Batjan (Dr. BleeJcer) ; Borneo (L. Dillwyn) ; Philippine 

 Islands (Cuming) ; Duke of York Island (Bev. O. Brown) ; Australia, 

 Bramble Key (J. B. Juices) ; and other Australian specimens with- 

 out special locality; Fiji Islands, Ngau (H.M.S. 'Herald'); and 

 Samoa Islands (Rev. S. J. Whitmee). 



A. White* refers to this species under the designation of P. megisto 

 (Herbst) ; but on examination of his figure t I find that Milne- 

 Edwards's citation of this as an imaginary (or manufactured) type 

 is correct ; and therefore I retain the name P. punctulatus, which 

 is usually adopted for the species (cf. Hilgendorf, Crust, in Von der 

 Decken's Eeisen in Ost-Afrika, iii. (1) p. 95, 1869). 



7. Pagurus guttatus, Olivier 'i 



As our specimen differs somewhat from the brief description pub- 

 lished, I subjoin the following : — 



The carapace is depressed, with the postfrontal, lateral, longi-
