Edmondson — Crustacea from Palmyra and Fanning Islands g 



Family GECARCINIDAE 



Cardisoma rotundum (Quoy and Gaimard). 



Cardisoma hirtipcs Dana, U. S. Expl. Exped., vol, 13, Crust., p. 376, 1852; pi. 24, 

 fig. 2, 1855. 



The species is known from Madagascar, Farquhar Atoll, and numerous 

 other localities in the Indian Ocean. In the Pacific it ranges from the Liu 

 Kiu Islands eastward to Guam, Fiji, Auckland, Tahiti, and Hawaii. Three 

 specimens were taken at Palmyra and i at Fanning Island. 



Cardisoma carnSfex (Herbst). 



Cardisoma caniifcx Alcock, Journ. Asiat. Soc. Bengal, vol. 69, p. 455. 1900. 



The species is known from Madagascar throughout the Indian Ocean 

 to the Andamans and Pondicherry. Its range through the Pacific is east- 

 ward to the Society Islands and the Tuamotus. Streets previously reported 

 the species from the Fanning Group. Palmyra probably represents the 

 northern limit of its distribution. The species does not inhabit Hawaii. 

 In the Bishop Museum are 2 specimens from Palmyra and i6 from Fan- 

 ning Island. This burrowing land crab is very abundant on both of these 

 islands. Although the species functions as a scavenger it has become very 

 obnoxious to the human inhabitants of Fanning Island by reason of its 

 numbers and habits. 



Family GRAPSIDAE 

 Grapsus grapsus tenuicrustatus (Herbst). 



Grapsus maculatns var. tenuicrustatus Kingsley, Proc. Acad. Nat. Sci. Phila.. 

 1880, p. 193. 



Records of the species are from Ceylon, the Bonin Islands, Marcus 

 Island, Guam, the Tuamotus and Hawaii. Streets recorded it from the 

 Fanning Group as Grapsus rudis Milne. Edwards. According to Rathbun' 

 the subspecies is characteristic of the islands of the Pacific while the species 

 Grapsus grapsus (Linnaeus) is confined to the continental border of 

 America. Six specimens were taken at Palmyra and i6 at Fanning Island.
