SMITHSONIAN MISCELLANEOUS COLLECTIONS 



Genus GALATHEA Fabricius 



In the male of this genus the genital organs of the fifth coxae are 

 not exserted. The segments of the abdomen are all provided with 

 appendages ; those of the first two pairs are copulative, and those of 

 the next four pairs are of small size, simple and flattened. 



This genus is found in all seas of the old world. It is remarkable 

 that no species is found in the American waters except those of the 

 frigid zones, although it is represented on the west coast by the genus 

 Plenronchodes. The following is a list of species known besides 

 those herein described :

Carapax rather short and broad ; broad posteriorly ; surface stri-

 setose above, and with a few spines on the margin ; fingers de- 

 pressed, not gaping, and together nearly as broad as the palm ; their 

 inner margins armed with one or two slight teeth. Color reddish, 

 with some bluish on the carapax ; fingers of the hands tipped with

 0.29; breadth, 0.215; length of the rostrum, 0.09; of the chelipeds, 

 0.56 inch.
