The name now used antedates Hume's mandellii by a few mouths and must be adopted.
Nidification. Similar to that of the preceding birds. A nest taken by Captain Steen was placed about two feet down the burrow of a mouse-hare and the four eggs it contained measured from 21.6 x 15.0 to 24.1 x 17.1 mm. It was taken on the 19th June near Gyantse at an elevation of some 12,000 feet.
Habits. So far as is known, similar to those of the Common Tibetan Snow-Finch.
