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 y. 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. Bidley 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 antennae appear to be 
somewhat sharper, ar.d relatively longer, in the American indi- 
viduals than they are in the Eastern individuals that I have had 
an opportunity of examining.
