Terns were very common in the Strait between Koh Samui and 
Koh Pennan but generally kept far out to sea among the reefs. On 
a small island off Koh Pennan we obtained two beautiful specimens 
in full breeding plumage with the roseate tint of the under surface 
strongly developed and the streamers of the tail elongated. They 
were feeding amongst large numbers of the succeeding species. The 
only other specimens obtained within the limits of the Malay 
Peninsula are three shot in August on Pulau Jemor, a small island in 
the middle of the Straits of Malacca off the Selangor Coast.
