ventrals a little greater than its length. Disk broad. Head 
well depressed. Snout rather firm, only tip a little flexible, and 
median fontanel a little depressed. Eye about last 24 of head, 
elongate, and depressed above. Canthus well depressed. Mouth 
transverse below, dental edge well convex or slightly double-

scarcely free, and only edges of posterior flaps fringed. Nos- 
trils large, outside exposed width of mouth, and sending back 
a groove to corner of mouth and curving posteriorly towards its 
fellow behind this. Interorbital space broad and concave, though 
more or less flattened medianly. Gill-openings rather small. 
Spiracles broad, their width about half of eye. Body rough. 
An elongate-lunate cluster of large recurved thorns on each ante- 
rior edge of disk. On upper surface of tail 4 series of large 
curved thorns, 2 series on each side though none lateral, and 
but a few smaller thorns on middle of back. Supraocular and 
interorbital regions with small thorns. Anterior portions of 
pectorals above finely roughened, and transversely along outer 
portion of each an elongated cluster. On each side of back 
medianly some small thorns. A patch of recurved thorns at 
posterior basal portion of pectoral. Claspers finely asperous 
along external edges. Lower surface of body entirely smooth,

upper surface generally, mostly with small indistinctly defined 
spots of sepia about size of pupil, or but few larger, and scat- 
tered about at more or less regular intervals. Spots not extend- 
ing on edges of pectoral and ventral fins, or in fact very near 
margin of disk at any point, which is also more or less paler or 
translucent. On upper surface of disk also several large or
