Obs. In working over my Titmice of the Remiza group, I 

 found that two other forms from Asia should be considered 

 as distinct. One of them was brought by Przevalski from 

 Central Asia and was mistaken by Pleske for "JEgithalus " 

 stoliczkce, Hume; another is from Turkestan, and was named 

 by Severtzoff as JEgithalus jaxartensis, but never described. 

 Both birds should be considered as local forms of Remiza 

 pendulina. 



Remiza pendulina centralasi^e, n. subsp. 



JEgithalus stoliczkce, Hume apud Pleske. 

 R. pendulina simillima, sed paullo minor, rostro breviore et 

 graciliore, tectricibus alse minoribus intense isabellinis, 

 minime castaneo tinctis ; tectricibus alse majoribus 

 limbo apicali fere duplo latiore, quam in R. pendulina, 

 zona dorsi castanea angustiore. 



Hab. Asia centralis. 



Remiza pendulina jaxartensis, n. subsp. 

 R. pendulina valde simillima, rostro breviore et graciliore, 

 zona dorsi castanea (in avibus ejusdem setatis !) minus 

 saturata, tectricibus alas minoribus castaneo tinctis, sic 

 ut in R. pendulina, tectricibus alse majoribus limbo 

 apicali lato, ut in R. centralasiee. 

 Hab. Turkestan. 



Obs. Some new facts of distribution are also worthy of 

 attention. Heteropygia acuminata, Horsf., was met with in 

 summer in the Minusinsk district : three specimens were 

 killed, but none seem to have bred there. The Bustard of 

 Minusinsk Steppe and N. Mongolia (between Sayan and 

 Tannu-ola) proved to be Otis dyboivskii, Tacz., and is rather 

 plentiful there. No eastern Ducks are of regular occurrence, 

 with the exception of OHdemia carbo, Pall., which breeds in 

 Minusinsk district. Cygnopsis cygnoides, Pall., is a common 

 summer bird in N. Mongolia, and also breeds in Minusinsk
