COMMENTS ON THE PROPOSED DESIGNATION OF A TYPE-SPECIES FOR THE GENUS SPHAEROCORYPHE ANGELIN, 1854. Z.N.(S.) 1152 (See this volume, pages 231-233) By J. T. Temple {BirM)ech College, London) I write to support the application of C. J. Stubblefield and G. Henningsmoen [Z.N.(S.) 1152] on the proposed use of the plenary powers to designate a type-species for the genus Sphaerocoryphe. I consider that the actions they propose, both in regard to the designation of Sphaerocoryphe dentata Angelin, 1854, as the type-species oi Sphaerocoryphe and to the placing of the name Sphaerometopus on the Official Index, to be in the best interests of nomenclatorial stabihty and to be in harmony with past and current usage. By J. C. Harper {University of Liverpool) I have received an offprint of the paper by C. J. Stubblefield and G Hemiingsmoen in the Bulletin of Zoological Nomenclature 17 : 231-233. I give fuU support to the proposals therein concerning Sphaerocoryphe.
