On an apparently undescribed Pheasant from the Province of Zarafshan in Central Asia. By H E N R Y SEEBOHM, F.Z.S. [Eeceived April 5, 1892.] Through the kindness of Mr. Tegetmeier I have been able to add to m y collection an example of a Pheasant from Central Asia which appears to be undescribed. It is closely allied to Phasianus principalis, but differs from that species in having a very conspicuous white collar round the back of the neck but not quite meeting in front. It further differs from that species (and resembles P. per-sicus) in having no dark margins to the scapulars, and in having the dark tips to the feathers of the flanks and of the sides of the breast much narrower. From Phasianus mongolicus, which is also a ring-necked Pheasant, it differs in having the upper parts below the white ring brick-red, without any trace of the green reflexions so conspicuous in that bird. It further differs from that species (and resembles P. principalis) in having the feathers of the breast broadly margined with golden red, instead of being narrowly margined with black bronzed with green. It is also a smaller bird, with a smaller spur. It can scarcely be a cross between P. mongolicus and P. principalis, because the white ring is an absolutely perfect one in the most typical example of the former, whilst it is as absolutely free from the green reflexions which characterize P. mongolicus as the most typical example of P. principalis. The example of this apparently new species of Pheasant was sent to Mr. Tegetmeier by Lieutenant G. Tarnovski of Samarkand as a specimen of the Pheasant of the Zarafshan, described by that Russian sportsman in the 'Field' newspaper of the 21st of March 1891 (vol. lxxvii. p. 409), under the name of Phasianus zerafshanicus sive klossovskii; but in the detailed description of that species it is stated that " on specimens shot last autumn I found on nape and sides of neck from six to eight white small feathers invisible from without. O n the birds which are the subject of this description I have been unable to find any of these neck-feathers." From this statement it |
