to Pseudograpsus in all structural characters, that I do not 

 know whether it can be maintained as distinct. Pseudo- 

 grapsus peniciUiger is merely a more robust, thicker Hetero- 

 grapsus with greatly developed chelipedes. 



There are also three adult males of this species from the 

 New Hebrides (Aneiteum) in the Museum collection. 



I refer here with doubt a female in mutilated condition in 

 the collection of Dr. Bleeker from Celebes (Macassar). 



It resembles the male P. peniciUiger in all particulars 

 except that the carpus of the anterior leg is armed with a 

 distinct lobe or tooth on its inner margin, and the outer 

 surface of the penultimate joint, which is somewhat rugose, 

 is marked with a longitudinal raised line, which is continued 

 along the outer surface of the lower finger. Further material 

 is needed to show whether these characters are sexual or indi- 

 cative of a distinct species. As is usual in the females of 

 some allied forms, the chelipedes are entirely devoid of hair. 

 If distinct, this form may be designated Pseudograpsus den- 

 tatus. 



Ptycliognatlius pilipes ? 



? Gnabhograpsus pilipes, A. M.-Eclw. Nouv. Arch. Mus. Hist. Nat. iv. 

 p. 184, pi. xxvii. figs. 6-10 (1868). 



I refer to this species with some hesitation a small female 

 example from Batjan. It agrees very well with males and 

 females in the Museum collection from the Philippines (Gui- 

 maras). The close affinity of Gnathograpsus to Ptyclio- 

 gnathus was recognized by Prof. A. Milne-Edwards ; and I 

 can see no sufficient reason for regarding them as distinct 

 genera. It is worthy of note that neither A. Milne-Edwards, 

 Stimpson, nor Man have noted the common occurrence in the 

 females of this genus of a small tuft or patch of hair near the 

 distal end of the lower (immobile) finger of the chelipedes. 

 This hairy patch exists in the females I refer to P. pilipes. 

 It is possible that none of the authors above cited had females 

 before them. 



Metopograpsus messor (Forskal), 

 var. frontalis , nov. 



Celebes, Macassar. An adult male. 



In its coloration this example appears to approach very 

 near to what may be regarded as the typical form of the 

 species, represented by specimens from the Ked Sea in the 

 Museum collection. 



The front is relatively wider than in most of the specimens 

 of this species in the Museum collection — about three and a
