ZO()L()(;v OI' THH FAR KAST. 
In preparing my report on these fishes I am greatly indebted to Dr. N. 
Annandale and Dr. B. L. Chaudhuri, who had made a prehminary investigation 
of the specimens before I examined them and had separated them into their 
genera and in some cases into their species. To the former I am also indebted 
for numerous valuable suggestions during the preparation of this report. 
The types of the new species are preserved in the collection of the Zoological 
Survev of India. 
PLAGIOSTOMIA. 
Family CEvSTRACIONTIDAE. 
Cestracion blochi (Cuv.). 
1913. Cestracion hlochii. Garman, Mem. Mus. Comp. Zool. Harvard Coll. XXXVI, p. 156. 
This hammer-headed shark is represented by two specimens in Dr. Annan- 
dale's collection from the Tale Sap. The3' were obtained in the outer lake at 
Singgora. 
Cestracion hlochi is quite common in the seas of India and the Mala>' Archi- 
pelago. 
Family CARCHARINIDAE. 
Scoliodon walbeehmi (Bleek.). 
1913 Scoliodon walbeehmi, Garman, op. cit., p. 112. 
There are two fairly grown-up specimens of this .species in the collection. 
The largest is about a foot and a half in length. Of the two specimens one 
was taken near the mouth of the Patelung river in the inner lake in fre.sh 
water, while the other was captured in the outer lake at Singgora in brackish 
water. This species has not so far been known to occur in fresh water. 
Scoliodon ivalbeehmi is known from the seas of India, the Malay Archipelago 
and Japan. 
Family RHINOBATIDAE. 
Rhinobatus thouini (Laceped.). 
1913. Rhinohaiits thouini. Garman, op. cit., ]). 276. 
Rhinobatus thouini is represented by a single .specimen in Dr. Annandale's 
collection from the Tale Sap. It was captured in the outer lake at Singgora and is 
about 38 cm. in length. It can readily be distinguished from the other Asiatic 
species of the genus by the character noted down in Dr. Annandale's ' key to the 
Indian Species of Rhinobatus. The snout is spatulate and is constricted some 
distance behind the tip. 
This species is found in Red Sea, the seas of India and the Malay Archipelago. 
Family TRYGONIDAE. 
Trygon bleckeri Blyth. 
1909. Trygon hleekeri, Annandale, Mem. Ind. Mus. II, p. 26, pi. iii, fig. 9. 
There is a young male of this species in the collection. It is about 27 cm. 
across the disc and was obtained by Dr. Annandale in the outer lake at Singgora.
