1967 ; 249, formulated an emended diagnosis for this species and proposed its 



transfer to Gonyaulacysta. The generic transfer is, however, invalid in that the 



original place of publication cited was indirect (via the Downie & Sarjeant 



" Bibliography ") and not direct (I. C.B.N. Art 33 para. 1 and note 1). The 



emended diagnosis is considered applicable to this new combination.] Upper
