66 PODOPHTHALMOUS CRUSTACEA. 



lobes are much wider than in the other species and are two 

 or three times as wide as the spaces which separate the 

 internal suborbital lobes from the front. Lastly the exter- 

 nal maxillipeds resemble completely those of Pelocarcinus 

 Lalandei M. Edw. For the rest this landcrab presents all 

 the peculiarities in organisation, colours and outlines 

 of the carapace and of the legs described in Hylaeoc. 

 Humei W. Mas. ; therefore the other differences that may 

 exist , will be found only by a comparison of the speci- 

 mens itselves.

Hab. The single specimen that we have received, a male, 

 has been collected near the bay of Gorontalo at the island 

 of Celebes , probably in the forests or in the moors of that 

 locality. Hylaeocarcinus Humei lives in the Nicobar Islands, 

 Pelocarcinus Lalandei M. Edw. is a native of the New World. 



13. Macr ophthalmus Polleni Hoffmann. 



Hoffmann, Crustaces de Madagascar, p. 19, pi. IV. 



It seems to me very probable that this species be iden- 

 tical to Macropht. Latreillii Milne Edw. (Nouv. Arch du 

 Mus. t. IX, p. 278, pi. 13, fig. 3). I cannot find any 

 differences , but the question must remain undecided , because 

 we have no typical specimen of Macr. Latreillii M. Edw. 



14. Gelasimus perlatus Herklots. 



Herklots , Addit. ad Faun. Afr. Occ. p. 6. Milne Edwards, 

 Ann. Scienc. Nat. 1852, p. 151. 



This species is positively closely allied, perhaps even 

 identical to Gel. Tangeri Eydoux (Mag. de Zool. de Guérin, 

 1835, pi. 17). Herklots was merely in the possession of 

 a single adult male whose larger claw is but a little longer 

 than the carapace; we received afterwards however many
