simple, witli the lip slip^htly enamelled, and the Jirae descend- 

 ing obliquely from beliiud it. Long. 8, lat. scarcely 3 mill. 



A form slightly aproaching F. Swartzii, Homes, of the 

 Vienna basin, but in that species the canal is recurved, and 

 the lirjB sub-squamate, 



VoLUTA m'coyi. n. s. Shell narrowly ovate, thin, 

 smooth, shining, with a small obtuse uaticiform apex ; 

 whorls slightly convex and oblique with no other marks than 

 the lines of growth, aperture 1.3rd larger than the spire, acute 

 posteriorly and gradually widening to the anterior notch, 

 which is broad and scarcely recurved, columella with four 

 high oblique plaits. Long. 30, lat. 11, apertui'e long. 18, 

 lat. 5. 



Tekebra additoides. n. s. Shell very acute — lanceo- 

 lately turretted, somewhat solid, closely longitudinally ribbed 

 and finely transversely striate, ribs rounded, ivory like and 

 smooth, interrupted above by a rather broad shallow groove 

 in which they ai-e slightly deflected, but not entirely obliter- 

 ated, above becoming almost nodular ; interstices broad, 

 slightly concave, shining, equally and closely striate, which 

 disappears on the ribs, sutui'e sharply and deeply impressed ; 

 whorls 13, ribs nodular in 7th to 11th, two spiral whorls, 

 rugose only ; apex decollate ; mouth ovate, almost channelled 

 near suture ; inner lip reflected over columella, which is 

 twisted into four to six rugose folds, sloping down to the 

 siphonal notch. Long. 24, lat. 5. 



In this fossil the groove on the ribs and general form brings 

 it near to the Tasmanian T. addita and T. Icieneri, but the 

 whorls are closer and more numerous. It has a general re- 

 semblance to the Australian members of the genus. It is 

 very close to certain European miocene forms, notably T. 

 pertusa Bast., and T. hasteroti Nyst (formerly called T. diipli- 

 cata by Brocchi, by mistake identified with Linnc's shell of 

 that name), but from these it differs in being a smaller nar- 

 rower shell, and in the ribs being more numerous and finer. 



AsTEALiuM (Calcar) flindersii. n. s. Shell solid, tro- 

 chiform, not umbilicated, spire somewhat elevated, granular 

 and spiny ; whorls six, furnished at the base with lamellar 

 imbricated folds in the form of short spines, above which ate 

 five spiral unequal lines of round granulations, the uppermost 

 of which are the largest ; last whorl angular ; suture a broad 

 and deep groove with a line of granulations within ; aperture 

 subcircular ; columella flattened and concave ; outer lip angled 

 and channelled at the base ; base flat with many spiral gran- 

 ular or imbricated lira3. Alt. 17, diameter 13 mil. The short 

 spines and the coarsely granular lirse easly distinguish this 

 species.
