pleasure in nanaiiig tlie species. This specimen having the apex 

 absent, and tlie outer lip and the anterior end of the columella 

 broken off, as well as possessing two unusual small extra plaits 

 behind the others, looked so much more like a Fasciolaria than a 

 Valuta, that in my manuscript I used the former generic name 

 until I saw other specimens sho'wang the true character of the 

 notched anterior end, mammUlary spire, &c. 



There is no known recent or fossil species at all approaching 

 it in general characters. 



Rare in Oligocene Tertiary clays of Muddy Creek, near jimction 

 with Grange Burn, 5 miles from Hamilton. One very large imper- 

 fect specimen, presented by Mr. Hannaford, from the clays of Port 

 Fairy, Warrnambool, where it occurs with several other species of 

 the Mount Eliza beds. Rather rare in the clays near the foot of 

 Mount Eliza, in Hobson's Bay, from whence the perfect figured 

 specimen was obtained, as well as a few fragments of the spire, 

 with the large nucleus attached. Rare in the clays of Orphan 

 Asylum reserve, Fyans Ford, A* 28. Rare in the Oligocene Ter- 

 tiary clays near Mount Martha.

VOLUTA ANTI-CINGULATA (McCoy). 



Description. — Ovate ; spire moderately acute (apical angle varying; from 55° 

 to 65°, usually 60°), of 5 slightly convex sculptured gradually increasing- whorls, 

 and a rounded smooth small swollen nucleus of 1-| turns ; sutures turreted or sub- 

 canaliculate by a narrow, flattened, or hollow space, separating the sutural line of 

 conoidal tubercles, which are on the other side separated from the obtuse tubercular 

 ends of a nearly straight long'itudinal rib, by a deep spiral constriction or channel, 

 seeming to cut the ribs to the depth of the spaces between them ; body whorl 

 obtusely rounded at the shoulder, rounding abrujitlj' to the sub-sutural channel, and 

 conoidally attenuated, tapering to a narrow slightly emarginate front ; ribs thick, 

 obtusely rounded (usually 19, to 15 rarely, and in one case 24, in last whorl), usually
