3. Geocarcinus depressus. 



Geocarcinus depressus . . . Saussure. 



Carapace subcircular, slightly or not truncated upon 

 the postero-lateral faces, very flat and depressed, only 

 being prominent upon the gastric region ; the edges have 

 a decided crest, but cccupies only the anterior part, and 

 is very advanced near the edge, beside which it forms a 

 small tooth. Behind the external orbital angle there is 

 a small depression. The front is vertical. The anterior 

 border of the carapace, between the two external orbital 

 angles, is wider than the half of the carapace. It is not 

 smooth, but finely striated, subscaly ; its lateral faces 

 finely and densely plaited, and having the pterygostomian 

 regions covered with scaly folds. The internal suborbital 

 lobes are very narrow, almost prismatic, having a strong, 

 oblique, and very prominent ridge which divides the 

 inferior angle of the front. 



The fourth joint of the external maxillipedes is oval, 

 much less wide than the third, but not retracted in front, 

 and very little behind ; its anterior border is notched ; the 

 internal slightly bowed. 



The first pair of legs of equal size ; the fifth joint has 

 a tooth at its internal angle, and below this a smaller 

 tooth. The fourth joint of the walking legs has no spines 

 above, and the last joint has four rows of spines.
