the young as long as it is wide at its base ; humero-cubital process 

 elongated and rugose, having two rounded osseous projections 

 posteriorly; between the humero-cubital and occipital processes 

 is a third intermediate one, the scapular, directed somewhat down- 

 wards ; the basal bone of the dorsal fin considerably dilated 

 externally. Barbels the nasal short, the maxillary reach the base 

 of the pectoral fin, the' mandibular arise on a transverse line, the 

 external reach the gill-openings, whilst the internal are shorter. 

 Teeth none on the palate. Fins dorsal spine stout, from three 

 fourths to nearly as long as the head (in the adult comparatively 

 longest, as is also the pectoral spine), serrated posteriorly, and 

 sometimes rugose anteriorly ; length of the base of the adipose 

 dorsal four sevenths of that of the rayed fin, and equal to the length 

 of the interspace between the two fins : the adipose fin is one third 

 longer than high. Pectoral spine from as long as, to one fourth

longer than, the head, strong, flattened, denticulated internally and 

 serrated externally, each alternate tooth (in many, especially small 

 specimens) being directed anteriorly or posteriorly ; the pectoral fin 

 reaches the ventral, and the latter the anal, this last being highest 

 anteriorly. Caudal forked. Skin covered with small, pointed 

 elevations, which in the posterior part of the body are arranged in 

 parallel lines, they are also seen on the cheeks. When the fish is 

 captured the secretion from each of these orifices forms over it 

 a rounded incrustation, causing the skin to appear tuberculated. 

 Air-bladder large and not enclosed in bone. Colour yellowish 

 brown, banded or blotched darker ; fins with black bands or mark- 

 ings; all the barbels annulated with black. 



Jfab. Rivers and contiguous pieces of water, from Orissa, through 

 Bengal, Assam, and Burma ; attaining at least 5| inches in length. 

 Specimens from the Naga hills are more deeply coloured, and the 

 under surface of the chest is covered with the orifices of numerous 

 glands.
