as the interorbital space, and 14 in the snout. Gills 4, a slit behind at 
4th ; 15 very short gill-rakers on the lower half of the anterior limb. Pseud 
branchiae present. 
deep, compressed, the dorsal profile forming an uneven curve, 
which is somewhat gibbous anteriorly in the region of the dorsal spines, 
origin of the ventrals, and thence straight to the anal. Caudal жїз дыг 
short, moderately broad, rounded above and below and compressed laterally ; 
its er is equal to 1} that of the eye. 
whole fish, with the exception of the top of the snout and inter- 
cebat: space, is covered with small rugose scales (Plate 23, A) which cannot 
be distinguished from one another; the fish appears as though covered with 
coarse-grained shagreen, which is somewhat finer on the opercular bones. 
Lateral line very indistinct; commencing at the top of the scapula, it 
ascends obliquely to its highest point below the sixth and seventh dorsal 
spines; it then descends gradually, and, passing across the middle of the 
peduncle, extends to the base of the caudal rays. 
Mouth small, terminal, horizontal, the jaws equal when closed; the 
extremities of the j jaws are crowded with minute barbels, which are longest 
and most crowded on the mandible. Maxillary very small, its distal portion 
free, and reaching backwards as far as the hinder margin of the anterior 
wem. a narrow band towards each angle. А few slightly longer and 
r ones are found at the apices of both jaws. None on the vomer, 
rer es, or tongue. 
Snout smooth above, with a few detached spines on its lateral margins. 
Each nostril with a simple oval opening, which is placed subvertically on 
the snout in a line with the centre of the eye, and nearer to that organ 
than to the tip of snout. Interorbital space smooth. Above the anterior 
hard spines. Behind the eye curved extensions of the frontal bone spread 
upwards, and with their radii resemble outspread fans, which are separated 
mesially by a very narrow strip of rugose bone. Above the frontal the 
supraoccipital projects forward to the vertical of the centre of the orbit ; 
its edge is sharp and covered with hard flattened asperities. Preoperculum 
rugose, the margin strongly denticulated ; its angle is somewhat acute, 
and bears a cluster of spines. Operculum very finely rugose, covered with 
radii spreading downward and backward fanwise. Suprascapula very pro- 
nounced, reaching downward to the top of the operculum. Scapula largely 
exposed and covered with striae, as is the hinder margin of the coracoid. 
first spine is equal to one-half the diameter of the eye, while the fifth is 
ага and equals the height of the body. All the spines are of irregular 
flattened and striated и, Dorsal rays slender; the 
s Be is worn, and leaves a considerable portion of the rays free. 
Anal fin short, the length of its base equal to the distance between the 
anterior margin of the мы апа the posterior margin of the eye. 
It is similar to the dorsal in character, its two spines and first and second 
rays being depressible in a groove, while those beyond are placed on a
