THE CRUSTACEA OF THE BERMUDA ISLANDS. 539 



This single specimen was found in '97, in a tide pool at Castle 

 Island under masses of Sargassum with which it had undoubt- 

 edly reached the island, as it is' a sargassum-living form and is so 

 distributed throughout the warmer seas. I find on the rostrum 

 eleven dorsal, and four ventral teeth. 



Not before reported from the Bermudas. 



45. Leander affinis (Milne- Edwards). 

 PalcEinon affinis Milne-Edwards, Hist. Nat. Crust., II., p. 391, 



1837- 



Numerous specimens, usually with ova. Very common in 

 pools among the rocks on the shores of Castle Harbor, '97 

 and '98. 



As noted by Heilprin the number of rostral teeth varies • con- 

 siderably. The only difference from Spence Bate's description 

 (Chal., Macrura, p. 782) of his Australian form seems to be that 

 in the Bermuda form the ocellus is not clearly distinct from the 

 cornea of the eye, as Spence Bate gives it, but lies just within its 

 margin. 



Reported by Heilprin and Ortmann ; and by J. M. Jones as 

 PalcEmon vulgaris. 



Distribution : New Zealand (Dana); Port Jackson (Bate).
