446 STEENID^ MICRANOUS 



wing, the outer feathers considerably shorter than the central ones, 

 the fourth pair from the outside the longest ; tarsus short, clearly 

 less than the middle toe and claw. 



The Noddies, two species of which are recognised by Saunders, 

 are found throughout the tropical and semitropical seas of the whole 

 world. As a rule they are met with in the open sea or near oceanic 

 islands ; they seldom resort to the coasts of the continents.

 black ; upper parts dark brown, the primaries and tail a good deal 

 darker ; below dark brown with a leaden tinge on the throat, paler 

 on the under wing-coverts. 



Eyes, beak and legs blackish ; webs which extend to the tips 

 of the toes, ochraceous. Length about 15-0; wing 1O5; tail 6-4 ;

 lead colour on the throat and a dark line along the upper wing

Distribution. The Noddy, so called by sailors from its tameness, 

 and therefore supposed stupidity, is found throughout the tropical 

 and subtropical seas of almost all the world. It breeds on the 

 rocky islets off St. Helena and Ascension and on Inaccessible Island 

 near Tristan da Cunha in the Atlantic, also on Sandy Island near 

 Madagascar whence its eggs were obtained by Mr. Layard in 1856 

 during his voyage on H.M.S. " Castor." There are two examples 

 from " Cape Seas " in the British Museum.
