QUEENSLAND MOLLUSC AN NOT US, No. 3. 
name had been used many years before Jousseaurne selected it, a fact Schilder 
has since recognised. The beautiful shell isabella ! .ion. was placed by Schilder 
under Jousseaumea Sacco, introduced for a European fossil group of no real 
relationship, and I separate it under the name Basililrona, naming Isabella as 
type. The typical Cyprcea, as mentioned above, must be tigris Lam., so for 
the mappa group, wrongly so considered by Schilder, I introduce the new 
genus Lepori cyprcea, mappa being named as type, the very rare valentia being 
included but only tentatively. The very small “ Cyprreas” will need much more 
study before they can be regarded as being well distributed. The curious little 
irrorata Gray, allowed as monotypic of Naria, is not unlike the beckii series, 
from which it is widely separated by Schilder. 1 introduce Paulonaria with 
beckii Gaskoin as type and will work these out better later. Trivia is also well 
subdivided by Schilder, and the following comparison of Hedley’s species will 
enable us to systematise these better 
Trivia globosa Gray, 1832 
grando Gaskoin, 1848 
pellucida Gaskoin, 1846 
producta Gaskoin, 1835 . 
scabriuscida Gray, 1828 . 
staphylcea Linne, 1758 . 
sidcata Gaskoin, 1848 
vitrea Gaskoin, 1848 
Choir ivia pilvla K inner , 1845 
Trivirostra edgari Shaw, 1909 
DoUchupis pellucidula Gaskoin, 1846 
DoUchupis producta Gaskoin, 1835 
Trivirostra scabriuscula Gray, 1828 
Staphylcea staphylcea Linne, 1758 
Trivirostra sulcata Gaskoin, 1848 
Trivirostra vitrea Gaskoin, 1848. 
The small globular “ Trivias,” of which there is more than one species 
confused, are here separated with the new generic name Gleotrivia , pilvla Kiener 
being named as type, globosa being the American species. The forms with 
produced extremities, following Schilder, are separated, and the new genus 
name DoUchupis proposed, producta Gaskoin being selected as type. 
The Linnean species staphylcea was classed by Hedley under Trivia, but it is 
a Cyprseoid form, and it is suggested here that limacina Lamarck is probably more 
closely allied to erosa than to staphylcea. Again, carneola is given as type of Lyncina 
by Schilder, but the apparent type was lynx, and this was fixed by Tryon (Struct. 
Syst, Conch., vol. ii, p. 198, 1883), so that 1 introduce the new subgeneric name 
Mystaponda. with vilellus Linne as type. I have accepted a few emended specific 
names in the foregoing list, but probably many more will need consideration such as 
flaveola Linne, for which Hedley has noted hi MS. labiolineata Sower by as being 
probably the alternative name, and Schilder has used helence Roberts, 1868. Hedley 
also added cumingii to the Queensland list, and this species is referable to Cribraria. 
As to Hedley’s felina this name has been replaced by Schilder by listen Gray, and a 
new subgeneric name is here proposed for this form. M elicerona, of which a curious 
development occurs at North-west Island, having rostrate extremities and somewhat 
excavate under surface recalling the New Caledonian aberrations, which hitherto 
appear to have been restricted to that island. 
An addition to the Queensland list is Cyprcea rhinoceros Souverbie (Journ. 
de Conch., vol. xiii, p. 156, 1865), described from New Caledonia, which was also
