Five 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.

In 1872 V. Martens, in his paper "Ueber cubanische Crustaceen," 

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

 eastern coasts of America of a Falinurus, 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. Eidley obtained one specimen of a Panulirus^ 

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

 natus (Fabr.) ; and in addition to this specimen there is in the 

 British Museum Collection one other from Panama, which is 

 also, I believe, referable to P. ornatus (Fabr.). 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 the spines upon the 

 carapace and upon the peduncles of the antennsB appear to be 

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

 viduals than they are in the Ea.^tern individuals that I have had 

 an opportunity of examining.
