810 FISHES OF IXDIA. 



Zygcena dissimilis, Murray, Annal. and Mag. N. H. (5) xs, 1887, p. 304. 



Anterior edge of head nearly straight, and forming a more or less right angle with its 

 lateral maro-in. Length of the hind edge of one of the lobes equal to or rather exceeding 

 its widtli near the eye. Eyes — nostrils near them : but no groove running along the front 

 edo-e of the head. Teetli — oblique, as broad at their base as long, with an indistinct lateral 

 notch, and serrated on both edges. Colours — brownish gray, becoming white beneath. 



Hahitat. — Red Sea to Kurrachee where one, a little over 10 feet in length, was captured 

 in April, 1884.

MuiTay, Ann. and Mag. Nat. Hist. (5), xiii, p. 349. 



Said to differ from L. s-pallanzanii 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. Nat. Hist. 1887) I placed this shark instead of 

 Carcharias murrayi, Giinther, 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. 

 Hahitat. — Kurrachee. 



Page 722. Add Genus 2 — Odontaspis, Agassiz. 

 TriglocMs, Miiller and Henle. 



Spiracles minute and alove the angle of the mouth. No nictitating memlrane. Mouth wide 

 and crescent-shaped. Teeth large, awl-shaped, and with one or tivo cusps at the hase. Gill- 

 openings of moderate size. Tivo 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 teicuspidatus. 



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, Eafinesque. 



Month crescentic. No memhrana 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 betiveen 

 the pectoral and ventral fins : the second dorsal above the interspace betiveen the ventral and 

 anal, the latter being small. Caudal very long, with a pit at its commencement. No keel 

 on the side of the tail.

Body fusiform, gradually decreasing in size to the caudal fin, the great length of

 in length from Ceylon, having been procured from the Colombo market, February, 1884, 

 wherc°it was quite unknown to the fishermen. It is also found in the MediteiTanean, and
