Genus DAIRA De Haan 



54. DAIRA PERLATA (Herbst) De Haan 



Cancer perlatus Herbst. 



Cancer variolosus Fabricius, Suppl., p. 338. 



Da'ira perlatus De Haan, Fauna Japonica, Crust., p. 18. 



Lagostoma perlata Milne Edwards, Hist. Nat. des Crust., i, 387. 



Da'ira variolosa Dana, U. S. Expl. Exped., Crust., i, 203, pi. x, iig. 4. 



Found at the Amakirrima Isles, near Loo Choi^, by the officers of 

 the steamer "John Hancock," Captain Stevens Dana reports it 

 from the Samoan Isles. Milne Edwards gives the Atlantic Ocean 

 as its habitat. If this be not a mistake, we may well doubt whether 

 there ma}- not be two species confounded under the name. 



Dana rejects Herbst's name perlata, remarking that its meaning 

 is not pearly, but very broad. x\ll names where signification involves 

 an error should undoubtedly be rejected, but in this case we have no 

 reason for deciding with certainty that the latter meaning is not that 

 actually intended by the author.
