Sykes says his Ageneiosus childreni is termed Purree, Mahr., and 

 Sillun in the Decean, that it is without cirri, and also that the first 

 bony ray is " serrated on the anterior edge," this being also shown 

 in the figure. The long maxillary barbels of this species serve to 

 distinguish it from S. ganyetica. 



Hab. Kivers of the Decean and the Kistna and Godavery to 

 their terminations.

Length of head 5J, of caudal fin 5| to 6, height of body 5 to 5| 

 in the total length. Eyes with narrow anterior and posterior 

 adipose lids; diameter 4 to 4 in the length of head, 3^ to 1| 

 diameters from the end of snout, and 2 apart. The width of the 

 head equals its length excluding the snout, whilst its height is 

 rather less. Lower jaw the longer, snout rather broad, the width 

 of the gape of the mouth exceeding half the length of the head. 

 Barbels a pair of minute maxillary, but no mandibular ones. 

 Teeth in the jaws villiform, and in a crescentic band across the

 behind the middle of the eye, anteriorly smooth or rugose, pos- 

 teriorly finely serrated in its upper portion. Pectoral spine 

 stronger, as long as head without the snout, and serrated in- 

 ternally. Ventral fin arising under the posterior dorsal rays, and 

 nearly reaching the anal. Air-bladder small, with its lateral 

 edges protected by a short osseous process from either side of the 

 vertebra, but it cannot be said to be enclosed in bone. The air- 

 bladder itself, when opened, is found to consist of two oval chambers,
