BRACHYI7EA. 



Tribe IV. OXYRHYNCHA, H. Milne-Edwards. 

 Fam. 1. PISID JE. 



EURYNOME ASPERA (Pennant). 



It is E. scutellata, Risso, E. spinosa, Hailstone, and 

 E. boletifera, Costa. 



In deeper water on hard ground, all along the coasts, but 

 sometimes found inshore. 



MAMAIA SQUINADO (Herbst). 



Very common. 



The generic name Mam was already in use among Aves 

 when Lamarck first employed it for a crustacean in 1801. 

 Moreover, the genus, as defined by him, would not embrace 

 " Maia squinado." We are of opinion that Mamaia, Stebbing, 

 should be used, and that Parainaya of Herbst has no claim 

 (see Stebbing, ' Marine Investigations in (South Africa, 

 South African Crustacea,' pt. 3, 1905, p. 22, and Proc. Biol. 

 Soc. Washington, vol. xviii. June 1905, p. 157 ; and also 

 Mary Rathbun, Proc. Biol. Soc. Washington, vol. xviii.
