Remarks: This is the most common vv^estern Atlantic stomatopod. 

 As Hansen (1895, footnote) pointed out, the accessory carina on the 

 telson is the only difference between this species and the vridely dis- 

 tributed G. chiragra of the Pacific; the character, although minor, is 

 nevertheless constant. 



The color is extremely variable, usually a mottled green on a light 

 background. In the present material, the ventral surface of the males 

 is darker than that of the females, and this was the only sexual differ- 

 ence noted.
