ICHTHYOLOGY 
lated and covered posteriorly with radiated striae ; the 
posterior part of the upper surface of the head strongly- 
granulated ; the inferior portion of the preeoperculum forming 
a prolonged angle but no point ; the operculum pointed. The 
lateral line is straight and prominent, like in Polyommatus ; 
the first dorsal formed of nine spines j the first rather shorter 
than the second, and of about the length of the fourth ; the 
second dorsal has fifteen rays ; the caudal is emarginated and is 
formed of eight long rays and numerous shorter ones ; the 
anal of fourteen rays ; the pectorals are very large like wings, 
and attain the root of the tenth anal ray ; they are formed of 
ten rays ; the ventral s are large, of six rays. 
According to Mr. Bostock's notes, the fish, when alive, 
was of a lavender grey, with its lower parts silvery and 
of a light milky blue ; the dorsal spines pink, a black 
blotch extending on the upper and anterior part of the 
fin to the third spine ; the fins pink, with the posterior 
part of the caudal of a similar but darker colour; eyes 
blue ; the large pectorals of an olive green, with numerous 
oblong spots of a dull cobalt ; the eyes of the same colour ; 
a very large black blotch near the inner side; this blotch 
is also covered with spots; the three free pectoral filaments 
of the colour of the belly. 
I have received two specimens, preserved in liquor, each 
six inches long, and this is said to be the usual size of this 
sort, which is said to be very scarce ; but since, Mr. Bostock 
has sent me a dried specimen measuring eight inches. 
PENTAROGE MARMORATA. 
Apistus Marmoratus, Guv. and Val, iv., p. 416. 
Mr. Bostock says that it is called at Freemantle Devil fish, 
that the spines cause intense pain, and that it is dreaded alike 
by the native and the white population. 
PLATYCEPHALUS FUSCUS. 
Similar to the specimens from Victoria, the specimen is 
twenty-one inches long.
