RHYNCHOSTRUTHUS SOCOTRANUS, gen. et sp. nov.  (Plate XVII.)   RHYNCHOSTRUTHUS, gen. nov., ex fam.

Cauda mediocris, æqualis. Pedes mediocres, satis debiles; digitus internus externo paulo brevior; ungues debiles.   RHYNCHOSTRUTHUS SOCOTRANUS, sp. nov.  ..  Of this very curious new form of Sparrow four males are in the collection; unfortunately no female. The thick Coccothraustine bill renders it easily distinguishable from all other species of the Passerine group."
