SHARP-TAILED STINT. 
coloration however is quite of a different character : the throat is pure 
white ; the upper and lower-breast is greyish-brown with scarcely any rufous 
tinge and is boldly, heavily and regularly streaked with black ; the abdomen, 
flanks, and under tail-coverts are immaculate white. 
The adult summer-plumage of pectoralis differs very Uttle from that of 
the immature — the immature rufous edgings being lost ; otherwise no 
noticeable character can be given. 
These facts show that these birds cannot be regarded as very closely 
related, and consequently a correction is necessary in the recent Hand-List of 
British Birds by Hartert, Jourdain, Ticehurst, and Witherby, 1912, where 
(p. 175) they are classed together as subspecies under the names “ jE/roZm ” 
inaculata maculata and “ Erolia ” 7naculata acuminata, and the species-name 
used is “ Erolia ” inaculata. They are certainly quite distinct species, and 
the specific names to be used are acuminatus and pectoralis, whatever genus 
or generic names may be used in connection with these.
