Mr. Ogilvie-Grant also exhibited examples of the 

 Mongolian Black Grouse (Lyrurus teirix mongolicus Lonn- 

 berg), of which large numbers had recently been imported, 

 in a frozen condition, to the London market. He shewed 

 several very handsome Greyhens of this form, one of which 

 had the wing fully expanded to shew the great amount 

 .of white on the secondary-quills ; he also exhibited for 

 comparison a female of the typical Scandinavian Greyhen 

 with the wing expanded. The differences between the two 

 birds were very striking, not only as regarded the amount of 

 white on the secondaries, but also the colour and markings 

 of the upper and underparts of the body. The males of 

 L. t. mongolicus were also easily distinguishable from typical 

 L. tetrix, males of which were exhibited for comparison. 



Full particulars of this form were to be found in Prof. 

 Lonnberg's paper (cf. Orn. Monatsb. xii. pp. .105-9. 1904). 



The birds imported into (he London market came in 

 company with vast numbers of Pallas's Sandgrouse (Syr- 

 rhaptes paradoxus) and smaller numbers of Pallas's 

 Pheasant (Phasianus pallasi). They were said to have been 

 obtained on the western slopes of the Chingan range, which 

 separates Eastern Mongolia from Manchuria, but the exact 

 locality was somewhat doubtful. The birds described by 

 Prof. Lonnberg came from Mongolia, south of the town of 

 Urga. 



Through the kindness of Dr. J. A. Clubb, Curator of the 

 Free Public Museums, Liverpool, Mr. Ogilvie-Grant had 

 been able to examine the type specimen of Lyrurus derbianus 

 Gould (P. Z. S. 1837', p. 132), obtained by Askew in Russia
