Pive specimens were taken, two adult females, one with ova, 

 and one immature female, one adult male and one immature 

 male. 



The specimens described by Smith were from Pernambuco.

Inl872 V. Martens, inhis paper "Ueber cubanische Crustaceen," 

 Arch. f. Naturg. xxxviii. p. 128, recorded the occurrence on the 

 eastern coasts of America of a Palinurus, which he questionably 

 identified as P. ornatus (Oliv. ?), a species which appears to have 

 its head-quarters in the Indo-Pacific Seas. From Fernando 

 Noronha, Mr. Ridley obtained one specimen of a Panulirus, 

 which I cannot separate by any important character from P. or- 

 nahis (Pabr.) ; and in addition to this specimen there is in the 

 British Museum Collection one other from Panama, wlu'ch is 

 also, I believe, referable to P. ornatus (Pabr.). It will thus be 

 seen that this form occurs in the Indo-Pacific Seas and upon the 

 east and west coasts of America. 



It is perhaps of interest to note that tlie spines upon the 

 carapace and upon the peduncles of the antennse appear to be 

 somewhat sharper, and relatively longer, in the American indi- 

 viduals than they are in the Eastern individuals tliat I have liad 

 an opportunity of examining.
