5. DescripTION oF A New GENUS AND OF SEVERAL New SpE- 
CIES OF GAsTEROPODOUS Mouuusca, FROM THE CUMINGIAN 
CotLection. By ArtHur Apams, F.L.S. etc. 
(Mollusca, Pl. XXVII.) 
Larina, A. Adams. (Noy. gen.) 
Operculum annular, horny, ovate; elements concentric; nucleus 
intramarginal near the middle of the inner edge. 
Shell imperforate, semiglobose, thin; spire obtuse; whorls few, 
tumid, covered with an olivaceous epidermis, the last large and ven- 
tricose ; aperture wide, ovate ; outer lip simple, regular, acute. 
This genus seems most to resemble Amphibola, but the operculum 
in that genus is subspiral, and not annular. From the circumstance 
of “Moreton Bay” being given as the locality, it would appear to be 
marine, thus affording us another example of a marine air-breathing 
Gasteropod. 
1, Lartna Srrancer, A. Adams. (PI, XXVII. fig. 3.) L. testa 
suborbiculari, imperforata, vix rimata, tenut, ampullacea ; 
spira obtusa; anfractibus 3}, convewxis, transversim sulcatis, 
epidermide olivacea, sepius in lineis transversis elevata obtectis, 
anfractu ultimo ventricoso; apertura ovata, ampla; labro 
acuto, simplice. 
Hab. Moreton Bay (Mr. Strange). Mus. Cuming. 
In young specimens the epidermis is disposed in transverse spiral 
ridges, and the surface of the shell is conspicuously striated longitu- 
dinally ; in adult specimens the epidermis becomes abraded, and the 
surface exhibits some elevated transverse ridges.
