AMPHIBIA NANTES. SQUALUS. 
No. XYI. 
Squalus cirro ad nares ; corpore jasciato; pinna ani nulla ; cauda quarn corpus longiore. 
The Squalus with a cirrus at each nostril; the body variegated by cross bands ; no anal 
fin ; the tail longer than the body. 
Called by the Natives Bokee Sorra. 
The head, nearly as broad as the body, compressed, convex above, flat beneath; the crown a little depressed, 
rostrum soft, not transparent. The mouth, (as in the genus) beneath, three-fourths of an inch from the point 
of the rostrum; the nostrils close to the mouth, wide, with a short cirrus pendent from the interior edge of 
each; the eyes oval, pupil linear, transverse: behind each, there is a lunated aperture. The fifth spiraculum is 
covered by a membrane from the fourth, in a manner to be easily overlooked. 
The trunk short, oblong, tapering from the pectoral fin; the sides a little compressed, but becoming round 
at the dorsal fin, and tapering gently, it terminates in the long, flat tail. The skin rough. 
The fins. The pectoral large, nearly orbicular, extending as high as the second spiraculum; the roundish 
ventral fins rise about an inch and a half behind them; the first dorsal rises nearly two inches from the left 
spiraculum, and the second about two and a fourth from the caudal; the spinal portion of the caudal fin, thin, 
and narrow, uniting with the acuminated, angular, terminal portion; the lower portion is seemingly divided 
into two lobes, of which the posterior is the longest and broadest. 
The colour above, a dusky brown, intersected, from the root of the rostrum to the point of the tail, by twelve 
or thirteen broad fasciae of a brighter brown. The belly a dusky white. 
The length, from the nose, to the point of the tail, thirteen inches. 
No. XVII. 
Squalus cirro ad nares ; cor pore nonfasciato ; pinna anali nulla ; cauda quam corpus longiore. 
The Squalus with a cirrus at each nostril; no anal fin ; the tail longer than the body ; 
no fasciae on the body or tail. 
Called by the Natives Ra Sorra. 
This in its form and all the other characters agreeing with the species last described, was not drawn: the only 
difference was in the colour, which was a darkish gray, without any fascia?; the belly whitish. 
The length, nineteen inches.
