THE AFRICAN SWIMMING CRABS OF THE GENUS 

 CALLINECTES* 



BY MARY J. RATH BUN. 



This paper is supplementary to the one on ' The Genus Calli- 

 since the publication of which the writer has examined 

 the types of a number of species of doubtful position and has 

 been able to correct the synonymy. J It becomes necessary to 

 change the name of two species, larvatus to marginatus, tumidus 

 to exasperatus, and advisable to consider the subspecies, tumidus 

 gladiator, a species. One new species is added, C. latimanus.
