NO. 11 GARTH : DISTRIBUTION STUDIES OF BRACHYURA 619 



CHECK LIST OF GALAPAGOS BRACHYURA AND 

 TABLE OF EXTRA-GALAPAGAN DISTRIBUTION 



The accompanying table is intended to serve both as a check list of 

 Galapagos Brachyura and as a graphic recapitulation of previously dis- 

 cussed distributional relationships of the 120 brachyuran species known to 

 occupy the Galapagos littoral. 



An asterisk (*) indicates a family, genus, or species recorded for the 

 first time in the Galapagos as a result of the work of Allan Hancock 

 Expeditions. 



(t) indicates a species new to science as a result of taxonomic studies 

 made of Hancock Expedition collections. 



($) indicates a species which has not been taken again in Galapagos 

 waters since its type was obtained by Cuming circa 1829. 



The symbol x indicates the presence of the species itself in the faunal 

 division shown at the head of the column. 



The symbol x? indicates an early record of the species which is subject 

 to reasonable doubt. 



The symbol (x) indicates an unpublished mainland record obtai'ned by 

 explorations of the Velero III which sheds new light upon the distribu- 

 tion of the species. 



The letters an indicate the presence of an analogous species in the faunal 

 division shown at the head of the column. 



The word tie indicates the presence of a closely related, but not analo- 

 gous, species. 



A geographical name in parentheses indicates that the species, while 

 hardly a bona fide member of the mainland fauna listed at the head of the 

 column, occurs in such proximity to it that a common method of transpor- 

 tation to or from the Galapagos may have served. 



Species excluded from the list which follows and from the writer's 

 Galapagos Brachyuran Fauna (1946) for reasons stated therein include 

 the following: Calappa saussurei Rath., Teleophrys turnidus (Cano), 

 Panopeus bradleyi Smith, Pachygrapsus crassipes Randall, and Uca 

 macrodactylus (M. Edw. & Luc.) 



For the distributional purposes of this list, and without prejudice to the 

 writer's taxonomic studies, Epialtus peruvianus is considered conspecific 

 with Eupleurodon rathbunae, and Stenocionops macdonaldi with S. 

 triangulata.
