BLACK-THROATED DIALER. 333 



senibles tliat of a human beino- in distress. A few of this 

 species are said to be found in Russia, and on the inland 

 lakes of Siberia ; it is not uncommon in winter in Holland, 

 and some parts of Germany ; is very rare in France, but 

 young birds in winter have been sometimes by chance taken 

 as far south as Switzerland, Provence, and Italy. M. Tem- 

 niinck says that specimens from Japan exactly agree with 

 those found in Europe. 



The Black-throated Diver is found in the United States. 

 The bird figured from by Edwards was brought from Hud- 

 son*'s Bay, on the shores of which it is common. Sir Edward 

 Parry brought home specimens from Melville Peninsula ;

 dress. 



In the adult bird the beak is dark bluish-black ; in form 

 slightly inclining upwards ; the irides red ; forehead dark 

 grey, top of the head, and back of the neck light ash-grey ; 

 back, rump, and tail-feathers nearly black ; inter-scapular and 

 tertial-feathers with a square patch of white on each side of 

 the shaft, forming a series of transverse bars ; wing-coverts 

 black, with a few specks of white ; primary quill-feathers 

 black ; chin and throat black, divided by a half collar of 

 short white lines ; sides and bottom of the neck streaked 

 longitudinally with black and white lines; breast, belly and all 

 the under surface of the body, pure white ; flanks and under 

 tail-coverts dusky ; legs and toes dark brown outside, lighter 

 pale brown within. The whole length about twenty-six 

 inches ; wing from the carpal joint to the end of the pri- 

 maries, eleven inches and a half. Females are but little 

 smaller than males, and both sexes, when mature, have the 

 throat black, as repeated internal examinations have proved. 

 The Divers undergo a partial moult in the spring, and on the
