Weiukauff proposed Geiunnda as a sub-genus for tlie reception of 

 curittata Gray, speciosa Reeve, Dionilifera Pease, tjeniviata Reeve, grcef'ei 

 Weinkauff, and (ii)nibilis Weiukauff. From these Cossmann selected 

 genn)uda as type. It may be here observed that geninmtK should be 

 ascribed to Reeve, not, as is usual, io Hinds, for Reeve published it in 

 Apiil, 1843, and Hinds in October, 1843. 



The bead-row of the fascicle readily distinguishes this genus from 

 related forms. Between the smooth protoconch and the adult vrhorls tvpo 

 or three whorls intervene with descre[)ant sculpture of fine arcuate longi- 

 tudinal riblets. 



The genus is perhaps represented in the Australian Tertiary by 

 I'leurotoma sayceaini Chapman.''

On the identification of a friend, I reported*^ this as Tarn's grttiiosiis 

 Helbling, but on re-examination of the material I now regard this 

 Queensland shell as G. gnvfei.
