Two grown up individuals of this species were obtained l.y Dr. Aiinandale at the 
mouth of the Patalung river near I.ampam. These specimens are similar to those 
described by me from Dr. Smith's collection from Bangkok.

Tetraodon liuris is known from the rivers of Sumatra and liorneo and recentlv 
I have recorded it from the fresh waters of Siam.

This species is represented in the collection, by two specimens. They were 
obtained by Dr. Annandale at Singgora. 
Dav points out that " according to Bleeker, examples from the Malay Archipe- 
lago, have fewer rays than those from India, he gives D. 12-ij, A. 11-12." In my 
specimens there are j undivided and 10 divided rays in the dorsal fin, the last 
ray being divided to the base. The anal fin possesses two sim])le and () branched 
rays. 
The colour of the .specimen agrees with Day's description except there are no 
colour bands on the dorsal surface and that the under surface is uniformly whitish. 
Tetraodon finviatilis is found in the seas and estuaries of India and the Malay 
.\rchipelago. Its range probably extends considerably eastwards. 
SUMMARY AND CONCLUSIONS. 
The hsh-fauna of the Tale Sap comprises, so far as we know, no s])ecies, of which 
j-l were collected in fresh water in the inner lake, near the mouth and in the deltaic 
region of the Patalung river. Of the remaining 86 species, 10 (viz., Scoliodon walhee- 
Jimi, Hvpolophus sephen, Clarias batrachits, Clnroccntnis dorah, Panchax panchax, 
CAenops vittatus, Trichopodus trichopterus, Leiognathiis cqniilus, Apogon hyalosoma, 
Scatophagus argus) were taken both in the inner and in the outer lake, while the 
remaining species were collected only in the outer lake, mostly in the neighbourhood of 
Singgora. Scolidon walbeehmi, Apogon hyalosoma and probably Lciognathns equulus 
are recorded here from fresh water for the first time.
