Monod, 1956, of a probably syntype of Xanthodes rufopunctatus from 

 the Cape Verde Islands) . Also, Monod is probably correct in syn- 

 onymizing Xanthodes granosus A. Milne-Edwards and Bouvier, 1898, 

 with this species. Monod noted that there were five subapical hooked 

 spines on the gonopod of the syntype of X. granosus examined by him, 

 whereas he found only four m what he believed to be type-material of 

 X. rufopunctatus. The syntype of X. granosus in the collections of the 

 U.S. National Museum, however, has only four hooked spines (fig. 

 8c), whereas the gonopod of the Curagao specimen (fig. 86), which 

 otherwise closely resembles Monod's figure of the syntype of X. rufo- 

 punctatus, has five such spines.
