There seems little doubt that Raffles’ description of 
sumatrana applies to a young bird, little more than a nestling, 
of this species and that his name will therefore have to 
displace the generally used S. melanauchen.

The specimens dated February and March, which are in 
full or incipient breeding plumage have the mantle decidedly 
darker grey than the others or than any of a considerable 
series in the F.M.S. Museums from the Straits of Malacca 
southwards to Singapore and from Tioman on the East coast 
of the Peninsula. The wing in the five specimens ranges from 
328—355 mm. and the exposed culmen from 59—61, but the 
shorter winged birds as is so frequently the case in terns have 
the tips of the primaries abraded. 
The majority of the more southerly specimens, notably 
those from Tioman, appear to have a larger bill, 6:—64 mm. 
though two are smaller than any of the above specimens from 
Langkawi etc. measuring 56 mm. 
I have in part followed Stresemann (Nov. Zool. XXI) in 
not admitting the validity of T. b. edwardst, Mathews (types 
. from Ceylon) regarding it on the strength of the above 
specimens from Langkawi merely as a transitional ‘form 
between T. 6. velox (Cretzsm.) from the Red sea, and 7. 6. 
pelecanoides (King) from Australian Seas and not worthy of 
even a subspecific name. In any event I think that the spec:- 
mens from the extreme south of Tennasserim listed as edwards 
by Oberholser would in all probability be referable to T. 0. 
cristatus from China if that form is to be kept distinct from T. 
b. pelecanotdes, which is extremely doubtful.
