Boe Dei gibhe 26-2090 1 te; V. 6. 
Elongate, height below dorsal spine 4—4?/,, head 3'/,—3'/,, 
its width 17/, in its length. Dorsal profile somewhat irregularly 
and slowly sloping down to the rounded, blunt, somewhat 
spongy, thickened snout, prominent in front of the nearly trans- 
verse gape of mouth, the length of which goes nearly 2'/, times 
in head. Crown of head with furrows and granulate rugae, 
radiating from a central prominence. The proper occipital process 
with parallel borders, twice as long as broad, touching with

a broad truncate hindborder the cres- 
centic basal bone of the dorsal spine. 
This part of the occipital process ori- 
ginates from a triangular continuation 
of the occipital shield. The occipital 
shield has anteriorly a deep rounded incisure for the median 
fontanel, which narrows anteriorly. On both sides bordered 
by a ridge; besides a narrow bony ridge runs on both sides 
from the anterior border of the occipital shield to above the 
frontborder of the eye. Humeral process triangular, with a 
broad base and sharp posterior point. Eyes only anteriorly 
with a vestigial orbital ring; more than 5 times in head, 1'/, 
in snout, 2—2!'/, in the slightly convex interorbital space, 
which goes about 2'/, times in head. Maxillary barbels extend 
to the posterior border of the gillmembrane or somewhat farther, 
as also the shorter mandibulary barbels, the mental barbels 
'/, shorter. Dorsal equal to head or slightly shorter. Dorsal 
spine flattened, its frontborder slightly serrated only at its top, 
posterior border with rough teeth, its length much more than 
that of head without snout, in small specimens nearly equal
