PARUS 169 



Talltita, Swedish. 



Ad. (Norway). Differs from P. palustris in having the crown plain 

 black without gloss, the black on the nape continued further clown ; the 

 back paler and greyer ; the secondaries margined with light grey ; the tail 

 rounded, not even ; and the cheeks whiter. Culmen O4, wing 3*45, tail2'2, 

 tarsus 0*65 inch. 



Hob. Norway, Sweden, Finland, N.W. Russia, arid the 

 mountains of central Europe ; is said to have occurred in 

 England. 



Differs but little in habits from the Marsh Titmouse, but its 

 call note is easily distinguishable, being sharper and more 

 elongated as if divided into two notes. It also nests usually in 

 the forests, never by water, and constructs its nest of fine strips 

 of bark and occasionally a few hairs and feathers. The eggs 

 are, however, undistinguishable from those of P. palustris. 

 Moreover, the present species makes its own nest hole in an old 

 branch or stump, whereas P. palustris makes use of any suitable 

 -old hole. 



In the article above cited Dr. Kleinschmidt subdivides the 

 Northern Marsh Titmouse as follows, viz. Parus salicarius 

 (Central and W. Germany, the Rhine plain between Worms 

 and Bingen), P. salicarius murinus (Renthendorf, Germany), 

 P. salicarius accedens (mountains of central Germany to French 

 Switzerland at moderate altitudes), P. montanus (Alps), 

 P. montanus assimilis (Galicia), P. borealis, Selys-Longchamps 

 (Iceland), P. borealis colletti (W. Norway), P. palustris, Wallen- 

 gren nee. Linn. (Sweden), P. borealis, Liljeborg (N. Russia, 

 Archangel), P. borealis macrurus (Siberia, N. China), P. cam- 

 tschatkensis (Kamchatka), P. spec. nov. (Japan, Hondo, Shimot- 

 suke). Of these I have deemed it advisable only to recognise 

 P. salicarius from Scandinavia and N. Russia, P. macrurus 

 (s.n. P. laicalensis) and P. camtschatkensis.
