Laut (H. 0. Forbes) ; Keeling or Cocos Island (Lt. Burnaby) ; Fiji 



Islands, Nairai {//.M.S. ' Herald*) : and Samoa Islands (Rev. S. J. 

 Whitmee). 



From G. maculatus this species seems to be best distinguishable 

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

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



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



He des Roches, two adult males ; Providence Island, an adult 

 female (No. 210). 



The series in the Museum collection includes specimens from 

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

 Madagascar, Tamatave (Rev. Deans Cowan) ; Ceylon, Galle (Dr. 

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

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

 'Herald'). 



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

 Geograpsus rubidus, Stimpson, under which uamo specimens from 

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

 mann, with G. grayi. 



G4. Metopograpsus messor (Forskat). 



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



The distribution of this common species has been referred to in 

 the preceding part of this Report (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. Kingsley, in his recent revision of the Grapsidse*, 

 places the Grapsus (Pachygrapsus) ceihiopicus, Hilgendorf, as a dis- 

 tinct species in the genus Pccchi/grapsus, 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 Etoile Island, 13fms. (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) ; Yizagapatam (A. E. Craven) ; and the Korean 

 seas (Capt. H. St. John).
