Common in all the inland creeks and larger rivers in the

Lord Tweeddale says, B. of B., p. 163, tbat " Horsefield's 

 name javanica has priority ;" but as Mr. Gould pointed out 

 years and years ago, Horsfield's name in the Tr. L. S. could 

 not have been applied to this species, and later Mr. Saunders, on 

 examining the type, found that javanica, (Horsfield) really— 

 hybrida. 



987 ? — Sterna jerdoni, Beavan. 



This appears to be nothing but the young of melanogastra, 

 Tern. 



988. — Sterna minuta, Lin. 



Lord Tweeddale says that Ramsay procured a specimen of 

 this species at Tonghoo ; very probably the specimen referred 

 to belongs not to the European, but one of the other Asiatic 

 forms of this species already discussed, S. F., V., 324. 



We have not yet met with any form of this species in 

 Tenasserim.
