76 IOWA STUDIES IN NATURAL HISTORY 



W. by N. of Pelican Island, Barbados, 2 miles ; 75-80 fathoms ; 

 sand bottom ; May 15 ; sta. 3 ; 1 $ immature. 



This specimen unites the characters of G. harhata^ and G. 

 sigsbei,- as given in my monograph (pp. 26-27). It will be 

 noted there that all the specimens (4) of harhata recorded are 

 male, while both those of sigshei are female. The specimen in 

 hand has the lateral dentation of barbata, as shown in plate V, 

 while lacking a branchial ridge, an orbital notch, and a patch of 

 hair on the cheliped, which three characters link it to sigsbei. 

 There is a very small but sharp spine on the upper margin of the 

 arm and the inner angle of the wrist, not the prominent, curved 

 spine of typical barbata, nor the blunt tooth of sigsbei. 



Both barbata and sigsbei are recorded from off Grenada, and 

 barbata also from Gulf of Mexico and Straits of Florida,
