The Squalus, with a very broad, transverse, hammer-like head. 
Squalus Tjygama, Linn. S. M p. 399. 
Called by the Natives, Koma Sorra. 
The singular form of the balance, or hammer-headed shark, sufficiently distinguishes it, not only from others 
of the same genus, but from all other fish whatsoever. It has five spiracles on each side; the mouth is 
furnished with several rows of teeth; the eyes large, and the apertures behind them oblong; the anal and 
hinder dorsal fins small. 
The subject drawn, measured twenty-two inches. 
REMARKS. 
They are seldom found of a larger size at Vizagapatam; but are said, in other parts, to arrive to the size of 
four or five feet. 
No. XIII. 
Squalus rostro longo, ensiformi , osseo, piano, utrinqnc dentato, deniiculis semisagittatis. 
The Soualus with a long, sword-form, bony, flat rostrum, denticulated on each side, the 
denticles half-barbed. 
Squalus Pristis, Linn. S. JV. p. 241. 
Called by the Natives Yahla. 
The teeth on each side of the long rostrum, are not exactly opposite to each other; all of them are bearded on 
the posterior side. The mouth beneath, and the five spiracula on each side, as in the rest of the genus. Teeth 
granular. The eyes large, oval, prominent. Nostrils oblique, near the base of the rostrum; the foramina 
behind the eyes, linear, slanting. 
The back and sides convex, the breast and belly flat. The trunk from the first dorsal fin, diminishing rapidly, 
becomes rounder towards the tail. The anus is situated between the ventral fins, and partly covered by a 
membrane.
