Nidification and Habits. There is nothing on record about this fine Nuthatch, now represented b}'^ good series from Rippou, Thompson and Craddock in the British Museum. It has been found so far between 4,000 and G,000 feet and seems to be a forest bird.

Distribution. Baluchistan and Afghanistan to Ferghana in Turkestan and the Tianschan. Birds from the Tianschan seem to have more of a dull ruFous tinge on the breast and lower tin-oat as well as being rather bigger, and should possibly be kept separate; I cannot, however, distinguish S. n. ohscura from North, and East Persia.
