Prof Heller classifies (Reise Novara, pp. 94-95) the nineteen known species 
of Palinurus into two divisions, one of which, besides other details, has a 
rostrum, the other has not. He likewise describes the following species as 
having been taken during the voyage of the Austrian expedition : — 
Palinurus lalandii (EdWj), 1. c. p. 97, from St. Paul; P. ornatus (var. de- 
coratus) (Fab.), 1. c. p. 92, »om JaVft:; P, dasypus (Edw.), /. c. p. 100, from

M. Gerbe (Comptes Rendus, Dec. 26, 1864, p. 1101) main- 
tains that the animals of the genus Phyllosoma are the larva 3 of 
the genus Palinurus, and (7. e. J an. 9, 1865, p. 94) he describes 
the internal anatomy of the genus Phyllosoma, and compares it 
with that of the larvas of decapod crustaceans. 
The resemblance of the larvae of Palinurus to the genus PhyU 
losoma was first pointed out by the late R. Q. Couch at the 
meeting of the British Association at Dublin (1857). But when 
we first had an opportunity of observing the larvae of Palinurus, 
we came to the conclusion that the drawing bore a closer re- 
semblance to Phyllosoma than did the animal from which we co- 
pied our figure, in consequence of the former losing the rotund or 
convex character of the latter. M. Gerbe admits that this larva 
does not entirely correspond with the characters of Phyllosoma, 
that it presents no trace of pleopoda, and that the caudal extremity
