6. STERNA. 1]3 



middle toe and claw 0-7. Specimens with fully developed and uii- 

 abraded tail-streamers appear to be rare in collections ; it is 

 probable that they are longer in the male than in the female. 



Adult in luinter. The black in front of and above the eye less 

 marked ; otherwise similar. 



Immature. Like the above, but the crown greyish white ; nape 

 and a line backward from the eye dull black ; a faint grey line on 

 the upper wing-coverts ; outer primaries darker ; tail greyish white : 

 bill and feet yellowish brown. 



Younrj. Similar, but crown and nape mottled with dull brownish 

 black ; feathers of the mantle barred with ash and tipped with 

 dull white ; tail-feathers slightly mottled with ash-grey. 



In all its stages of plumage this is by far the palest member of 

 the group of Little Terns. 



Hab. New Zealand, Australia, chiefly south of the Tropic of 

 Capricorn, and New Caledonia.
