hind the middle of the body. The margin of the indistinct anal 
fin shows rows of points. The-lower parts of many of the 
chevrons blackish in the furrows ; punctured with black towards 
the caudal extremity. Both the dorsal and ventral margins are 
notched in an undulating manner; the latter is of an orange- 
colour. 
Leptocephalus Morrisi, Penn. 
Following Yarrell’s example, I unite LZ. Spallanzani, Risso, 
with L. Morrisi. In the ‘Iehthyologie de Nice,’ Risso described 
a fish under the latter name, which, as C. Bonaparte remarks, 
does not belong to it; but where it is to be placed, Bonaparte 
could not determine any more than myself. The Lepidopus 
pellucidus, Risso, from the description of which the name Kama- 
rina and whole passages of the text have been transferred into 
the description of Leptocephalus Spallanzani, likewise remains a 
doubtful species, although Risso cites it under his Z. Spallanzani. 
Bad as is the figure of L. pellucidus in the ‘ Ichthyologie de Nice,’ 
it cannot be believed that it was drawn from a true Spallanzani 
or Morrisi. It is also very probable that Rafinesque has de- 
seribed this fish, which is common at Messina, in his ‘ Caratteri ;’ 
but there is no loss to science in leaving his very bad descriptions 
undisturbed in this genus. According to the reports of Heckel 
and Keferstein, this species, like all the rest, lives in the open 
sea, and not in the sea-weed. They are caught in bottles by 
boys whilst bathing. 
\e diagnosis of this species, whieh is difficult to characterize, 
might be as follows :—Head large, with an obtuse, projecting 
snout; black points at the apices of the muscular chevrons, and 
along the intestine; fine points at the root of the anal and the 
end of the dorsal fins; caudal fin pointed. 
It is impossible to say more than this, for there are no other 
characters on which we can rely. There are individuals with 
teeth, with traces of teeth, and without teeth; others in which 
the body, and others, again, in which the tail is longest. In 
confirmation of this, I giye the measurements of twelve indi- 
viduals :—

Even the series of points along the vertebral column is not 
reliable; it very often disappears beyond the anus, but is still 
always distinctly visible towards the end of the tail. :
