Feb. 6.—Read, A description of the Plectrophanes Lap-

Prideaux John Selby, Esq. F.L.S. M.W.S. Ed. &c.* 
Lapland Bunting (Fringilla Lapponica Linn.), Emberiza 
calcarata Temminck ;— found in Leadenhall-market among 
Larks from Cambridgeshire. Fam. Fringillide V igors, Gen. 
Plectrophanes Meyer. This genus Mr. Selby states to be in- 
termediate between Alauda and Emberiza. It approaches the 
former in the thickness of the bill, and in the form of the feet 
and production of the hinder claw. Its affinity to Emberiza is 
shown in the peculiar form of the bill characteristic of that 
genus: it differs, however, in having the first and second quill- 
feathers nearly equal in length, and the longest in the wing.
