Rathbun, Mary J. The Grapsoid 

 crabs of America.

 No. 97, Jan. 25, 

 1918, pp. i-xxii, 1- 

 461, pis. 1-161, 

 figs. 1-172. 

 Part of a work projected 

 many years ago as a handbook 

 for the study of American crabs, 

 the main purpose being to give 

 a brief description with figures 

 of each species. This report 

 has been enlarged to include a 

 detailed catalogue of the speci- 

 mens in the National Museum 

 and greatly augmented by an 

 accumulation of material dur- 

 ing its preparation resulting in 

 the description of many new 

 species. Consequently the work 



Rathbun, Mary J. — Continued. 



has been expanded into four 

 volumes. The present one deals 

 with six families : Goneplacidae, 

 Pinnotheridae, Cymopoliidae, 

 Grapsidae, Gocarcinidae, and 

 Ocypodidae. Fifty-six genera, 

 235 species, and 3 sub- 

 species are described and al- 

 most all figured. The collec- 

 tions in the National Museum 

 form the basis of this bulletin, 

 which has been enriched by the 

 loan of the collection of Pin- 

 notheridae of Stanford Uni- 

 versity, the same of the Mu- 

 seum of Comparative Zoology, 

 and certain Pinnotherid type 

 specimens of the British Mu- 

 seum collection.

 donated to the collections of the 

 National Museum.
