Laut (Z?. 0. Forbes) ; Keeling or Cocos Island (Lt. Burnahy) ; Fiji 

 Islands, Nairai {H.M.S. ' Herald ') ; and Samoa Islands {Rev. S. J. 

 Whitmee). 



From. Q. maculatus this species seems to be best distinguishable 

 by its usually broader, less abruptly deflexed front, with straighter 

 margin, and by the more •widely transverse, shorter epistoma. 



63. Geograpsus grayi (M.-Mw.). 



lie des Eoches, two adult males ; Providence Island, an adult 

 female (No. 210). 



The series in the Museum collection includes specimens from 

 Egypt (Sir J. Q. Wilkinson) ; Mauritius ; Zanzibar (Sir J. Kirk) ; 

 Madagascar, Tamatave (Bev. Deans Gowan) ; Ceylon, Galle (Dr. 

 W. Ondaatje) ; Loyalty Islands, Lifu (Rev. S. J. Whitmee) ; 

 Mare (W. WyJceham Perry); and Fiji Islands, Matuka (H.M.S. 

 'Herald'). 



Mr. Eangsley has already (t. c. p. 196) noted the identity of 

 Oeograpsus rvhidux, Stimpson, under which name specimens from 

 East Africa and Eeunion are referred to by Hilgendorf and Hoff- 

 mann, with G. grayi. 



64. Metopograpsus messor (Forshal). 



Mahe Island, beach (No. 196) ; a male. 



The distribution of this common species has been referred to in 

 the preceding part of this Eeport (p. 245.) The specimen from Mahe 

 Island appears to belong to the variety designated by M.-Edwards 

 M. intermedins, characterized by the larger markings of the carapace, 

 the front is only very obscurely denticulated. 



Mr. J. S. Engsley, in his recent revision of the Grapsidae*, 

 places the Chrapsus (Paehygra^psus) cethiopims, Hilgendorf, as a dis- 

 tinct species in the genus Pa/ihygrapsus, being apparently unaware 

 that Hilgendorf has himself admitted the correctness of Kossmann's 

 identification of this species with M. messor f. 



65. Liolophus planissimus (Herbst). 



Thirteen specimens (among them but one adult male) were 

 obtained at Darros Island on the beach (No. 200), and a very small 

 male at EtoUe Island, ISfms. (No. 191). 



Since my revision of the genus in 1878 J specimens have been 

 added to the Museum collection from Ascension Island (Staff- 

 Surgeon T. Conry) ; Vizagapatam (A. E. Graven) ; and the Korean 

 aeas (Gapt. H. St. John).
