the sperm canal is moderately defined. All the examples have a 
perfectly smooth surface and are pale buff in colour with minute 
yellow-brown chromatophores, interspersed with a few larger ones. 
“The two alternating longitudinal rows of large light-coloured 
chromatophores ’’ described by Berry as decorating the outer 
surface of each arm are very conspicuous in the present specimens 
in parts where the outer skin has been rubbed off.

This would appear to have been preserved in alcohol for a 
long period, all trace of chromatophores having faded, leaving the 
specimen of a uniform dull pale-green colour. Body ovoid, firm, 
much wrinkled, but appearing to possess many tubercles on the 
dorsal surface and to be smooth below. A narrow fold of skin, 
more developed laterally than posteriorly, divides the dorsal from 
the ventral region. Hoyle (1886, p. 89) says with regard to a 
similar character in P. australis: ‘‘It is doubtful what value 
‘is to be attached to the raised ridge mentioned above; it is to 
‘“ be seen in other species under certain conditions, possibly due 
“either to different modes of preservation or to varying states 
‘ of contraction ; nevertheless, in the majority of formsit is never 
observed, and I am therefore inclined to attribute to it a 
“ certain systematic importance.” 
This example does not, however, agree with any of the 
species hitherto described as possessing a carinated membrane. 
The head is a little narrower than the body and there is a large
