RHYNCHOSTRUTHUS SOCOTRANUS, gen. et sp. nov.  (Plate XVII.)   RHYNCHOSTRUTHUS, gen. nov., ex fam. Fringillidarum.  Char. gen.  Rostrum crassum, tumido-rotundatum, culmine distincto, tomiis introrsum rectractis, maxilla curvata, commissura curvata, gonyde conspicue adscendente; naribus in fossa basali positis, setis brevibus incumbentibus obtectis.  Alæ longiusculæ, caudæ dimidium superantes, remigibus 1-3 cæteris longioribus, æqualibus, rem. 4to parum breviore. 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."
