but in its upper part the whole web is white ; the next rec- 

 trices have only a white margin on the upper part of the 

 outer web. The quills are dark brown, with yellowish-white 

 margins on the outer webs and tips, similarly tipped on the 

 secondaries; the outer web of the primaries is altogether 

 white ; the tertiary quills, as well as the upper wing-coverts, 

 have a wide border the same colour as the back. The lining 

 of the wings and feathers under the shoulders are white. 



The female, like others of the genus Otocortjs, has a nar- 

 rower black belt on the breast ; the sides of tlie throat and 

 head are blackish brown (they are black in the male), be- 

 coming sandy yellowish on the crown, assimilating to the 

 upper part of the body. 



This species — named by me after my travelling companion, 

 P. P. Teleschow, senior subaltern of the Trans-Baikaliau Cos- 

 sacks, who prepared the skins of all specimens obtained on 

 my fourth journey, and actively cooperated in the general 

 work of the expedition — frequents the mountainous border 

 of Northern Tibet, in the region between the gorges of the 

 Cherchen and Khoten, i. e., the newly discovered Russian 

 range and that of Keria. Besides this, 0. teleschowi was 

 first met with by us in the Chamen-tagh range, on the Tibetan 

 plateau, to the west of Gass. It is, however, more common 

 in the Russian range, where it haunts springs and rivulets at 

 the entrances of defiles along the northern foot of the moun- 

 tains. Its note, flight, and habits are not distinguishable 

 from those of 0. albigula, which it replaces in the above- 

 mentioned ranges. 



XLI. — Description of a rare Species of Plover from the 

 Cameroons Coast. By Captain G. E. Shelley, F.Z.S. 



Mr. H. H. Johnston has recently sent home a small collec- 

 tion of West African birds, procured by him in the swampy 

 marshes of the Rio del Rey, near the Cameroons. This col- 

 lection contained two specimens of a Plover entirely un- 

 known to me, so I consulted Mr. Seebohm, who is preparing
