FamUy MAIIDAE, 

 Genus M A i A, Lamarck. 



MAIA SQUINADO. 



Cancer squinado, Rondeletius, liv. xviii., p. 401. — Herbst, 

 Krabben und Krebse. tab. Ivi. 



Maia squinado, Latreille, Hist. Nat. des Crust, t. vi., p. 93. — 

 Bell, Brit. Crust, p. 39. 



A specimen said to have been taken off Dunoon 

 was exhibited before the Natural History Society, 

 Glasgow, by Dr. Fleming, in January, 1878. It is also 

 stated to have been dredged by Major Martin off 

 Ardrossan, and by Dr. Grieve on the west side of 

 Bute. From the fact that this crab is in Britain 

 almost confined to the south coast, it seems 

 probable that some other species may have been 

 mistaken — possibly Lithodes maia.
