Dr. Jerdon remarks:--"I once found its nest in a deserted bungalow at Kallia, in the corner of the house. It was made chiefly of the down of hares (_Lepus nigricollis_), mixed with feathers, and contained six eggs, white spotted with rusty red." The eggs resemble in their general character those of many of our English Tits, and though, I think, typically slightly longer, they appear to me to be very close to those of _Parus palustris_. In shape they are a broad oval, but somewhat elongated and pointed towards the small end. The ground-colour is pinkish white, and round the large end there is a conspicuous, though irregular and imperfect, zone of red blotches, spots, and streaks. Spots and specks of the same colour, or occasionally of a pale purple, are scantily sprinkled over the rest of the surface of the egg, and are most numerous in the neighbourhood of the zone. The eggs have a faint gloss. Some eggs do not exhibit the zone above referred to, but even in these the markings are much more numerous and dense towards the large end. In length the eggs vary from 0·65 to 0·78, and in breadth from 0·5 to 0·58; but the average of thirty-eight is 0·71 by 0·54, so that they are really, as indeed they look _as a body_, a shade shorter and decidedly broader than those of _P. monticola_. 34. Parus monticola, Vig. _The Green-backed Tit_. Parus monticolus, _Vig., Jerd. B. Ind._ ii, p. 277; _Hume, Rough Draft N. & E._ no. 644. The Green-backed Tit breeds through the Himalayas, at elevations of from 4000 to 7000 or 8000 feet. The breeding-season lasts from March to June, and some birds at any rate must have two broods, since I found three fresh eggs in the wall of the Pownda dak bungalow about the 20th June. More eggs are, however, to be got in April than in any other month. They build in holes, in trees, bamboos, walls, and even banks, but walls receive, I think, the preference. The nests are loose dense masses of soft downy fur or feathers, with more or less moss, according to the situation. The eggs vary from six to eight, and I have repeatedly found seven and eight young ones; but Captain Beavan has found only five of these latter, and although I consider from six to eight the normal complement, I believe they very often fail to complete the full number. Captain Beavan says:--"At Simla, on May 4th, 1866, I found a nest of this species in the wall of one of my servant's houses. It contained five young ones, and was composed of fine grey pushm or wool resting on an understructure of moss." At Murree Colonel C.H.T. Marshall notes that this species "breeds early in May in holes in walls and trees, laying white eggs covered with red spots." Speaking of a nest he took at Dhurmsala, Captain Cock says:--
