It is to this form that I made a passing allusion when discussing 

 Uca arcuatus (de Haan) in 1917. While Uca marionis (Desmarest), 

 1823, or Uca cultrimanus (White), 1847, may possibly claim priority, 

 on a comparison of figures and descriptions Dana's i.itidus seems to 

 have the clearest title to recognition. The much older name, voca?is, 

 used by Milne Edwards cannot be identified with the original species 

 entitled to that name. 



Our Durban specimen measures 23 mm. in breadth by 16 mm. in 

 length. The hand of the large claw is 44 mm. long, the fixed finger 

 slightly outreaching the movable one, its cutting edge traversed with 

 granules of which one is prominent at the base, another about midway, 

 and a large triangular lobe preceding the outdrawn apex. "The 

 crests on the inner surface of the palm are extremely prominent," as 

 described by Alcock. The front is exceedingly narrow.
