FISHES OF INDIA. 
Zygcena dissimilis, Murray, Annal. and Mag. H. H, (5) xx, 1887, p. 304. 
Anterior edge of head nearly straight, and forming a more or less right angle with its 
lateral margin. Length of the hind edge of one of the lobes equal to or rather exceeding 
its width near the eye. ISyes — nostrils near them : but no groove running along the front 
edge of the head. TeetJi — oblique, as broad at their base as long, with an indistinct lateral 
notch, and serrated on both edges. Colours — brownish gray, becoming white beneath. 
Eahitat. — Red Sea to Hurrachee where one, a little over 10 feet in length, was captured 
in April, 1884.

Murray, Ann. and Mag. Hat. Hist. (5), xiii, p. 349. 
Said to differ from L. spallanzanii in having f | teeth on either side, and the dorsal fin 
being a little further behind the base of the pectoral. 
By an error in transcribing (Ann. and Mag. Hat. Hist. 1887) I placed this shark instead of 
Carcliarias murrayi, Gunther, as a synonym to Garcliarias ellioti. It occurred owing to 
having noted, after having examined the type that Murray’s shark from Kurrachee, that it 
seemed to be identical with Elliot’s shark from the coasts of India. 
Habitat. — Kurrachee. 
Page 722. Add Genus 2 — Odontaspis, Agassiz. 
Triglochis, Muller and Henle. 
Spiracles minute and above the angle of the mouth. No nictitating membrane. Mouth tvide- 
and crescent-shaped. Teeth large, awl-shaped, and with one or tivo cusps at the base. Oili- 
opening s of moderate size. Two spineless dorsal fins, the first opposite the interspace between 
the pectoral and ventral : the second dorsal and anal not much smaller than the first dorsal.. 
A pit present or absent at the root of the caudal fin. 
Geographical distribution. — Temperate and tropical seas. 
1. Odontaspis teicuspidattjs. 
Carcharias tricuspidatus, Day, Fish. India, p. 713, pi. clxxxvi, fig. 1. 
Dundanee, Sind. 
This fish was formerly placed as a Carcharias, owing to the presence of a pit at the root 
of the caudal fin as observed at page 722. 
Genus 3. — Alopias, Rafinescjue. 
Mouth crescentic. No membrana nictitans to the eye. Spiracles minute, close behind the 
orbit. Teeth of rather small size, flattened and triangular, having smooth edges. Gill- 
openings of medium size. The first dorsal fin spineless, inserted above the interspace hehveen 
the pectoral and ventral fins: the second dorsal above the interspace betiveen the ventral and 
anal, the latter being small. Caudal very long, ivith a pit at its commencement. No heel 
on the side of the tail.

which is about half of the total. Nyes — rather large. Hostrils beneath and nearer the 
anterior border of the mouth than the end of the snout. Gill-opening of median size,.

the last two being over the pectoral fin. Teeth — about the third or fourth tooth 
on either side of the centre of the upper jaw smaller than the others.

Paris Museum, and Mr. Haly in the Tabrobanian, 1886, i, p. 167, records one 8 ft. 8 in. 
in length from Ceylon, having been procured from the Colombo market, February, 1884, 
where it was quite unknown to the fishermen. It is also found in the Mediterranean, and 
has been obtained from San Francisco Bay, California, and Hew Zealand.
