another subspecies of C europeeus, but by no means inter- 

 mediate between tbe latter and C. unwini. Besides the 

 specimens of C. plumipes from Mongolia and Tschinas in 

 Turkestan, from the St. Petersburg Museum, I have before 

 me one from Kandahar, in Afghanistan, and one from the 

 Dolan district, about thirty miles from Yarkand, collected by 

 Dr. Scully. The latter specimen, which is as unmistakable as 

 that from Kandahar, is mentioned in 'Stray Feathers,^ (iv. 

 p. 133) under the name of Caprimulgns eegyptius; but a 

 footnote by the editor clearly indicates that be was very 

 uncertain about this identification, and there is no doubt 

 that the mistake only happened from want of specimens 

 of the true C. cpgyptms. Although in the coloration of 

 the upper surface C. plumipes has a faint resemblance to 

 C. (Bgyptius, it can never be mistaken for that bird, the white 

 (not pale rufous) bands or sinuations on the inner webs of the 

 primaries and the quite different dark markings of the upper 

 surface being sufficient to distinguish the latter. 



But other Goatsuckers are found in Turkestan. The true 

 Caprimulgus (Bgyptius occurs in the sandy plains of the 

 north-western districts, as C. arenicolor of Severtzoff (types 

 examined) is exactly similar to African specimens of this 

 species. 



The pale C. europceus unwini, as before mentioned, is not 

 rare in several parts of Turkestan. The C. e. pallidus, 

 Severtz., is the same as C. e. unwini, but among Severtzoff^s 

 specimens is at least one that is intermediate between C. e. 

 unwini and C. e. plumipes. 



But these are not the only Caprimulgidse which inhabit 

 Turkestan, as I have before me two specimens from the 

 St. Petersburg Museum that are undistinguishable from dark 

 w^estern specimens of C. ewopceus ! I have, however, reason 

 to belic;ve that this latter is not resident in Turkestan, but 

 only occurs there as a wanderer, perhaps from S.W. Siberia. 

 In Siberia probably both C. europaus and C. e. unwini are 

 found breeding, although, of course, not in the same 

 localities, the former being most likely met with more to 

 the north and in the forests. C. e. umvini seems to grade into
