In form resembling T. paiiutp, Crosse, and T. hnnloji, Ang, 

 but easily distinguished by its long canal and peculiar lamel- 

 lose striations. N. Coast. "W. F. Petterd. 



No. 2. Raxella epitrema. n.s. R.t. late ovata, albida, vel 

 paUidissime fidni, ad sitturas conspicue profundeque canaliculata ; 

 aitfr. 0, lindis d nodosis, Jiris marjnis et parvis alternantibus, supra 

 varices traiiscKniibus ; nodis in spira costiformihis, in ult. anfr. 4 

 series transrcrsalibns ; varicibus ad suturas curvatis, in serie^n non 

 scqucntibus sed aliquantuhim a scipsis semotis ; apertura ovata; labro 

 cunspicuo, marginato, intus dentato, labio reflexo ; canali obliquo breve 

 fix recurvo. Lat. 23. Lat. 10. Mil. 



This very remarkable Ranella is distinguished by its deep 

 canaliculate suture which causes the varices to overlap in a 

 singular hooked manner. It does not appear to have any 

 living congeners in any way resembling it and none fossil.

Shell narrowly ovate, sub-turretted, solid, white, with a 

 broad pale chestnut baud (two on last whorl) scarcely shining ; 

 whorls 7 sloping, slightly convex, spirally multi-lirate ; lirae 

 regular, sub-distant, and decussate with obsolete longitudinal 

 ribs ; aperture scarcely equalling the spire, narrowly ovate ; 

 suture well impressed, labrum acute, columella solid, obliquely 

 triplicate. Tamar Heads. W. F. Petterd. Obs. Agreeing 

 in form, size, and general habit with M. ladia and other 

 similar Australian forms, but differing in being strongly de- 

 cussate. Most of our Mitras are smooth.

 castanea, pallidc zonata ; anfr. convexis, vix rotundatis, regidariter

This unique specimen was in the collection of Mr. Eonald 

 Gunn who had obtained it from the North Coast. It was 

 labelled with the above name by W. Swainson and marked 

 with his initials, though I cannot find that he ever described 

 it. In shape it is not unlike our common Mitra, except that 

 the spire and last whorl are about of equal length. Its shin- 

 ing, almost enamelled appearance and close granulose fine ribs 

 distinguish it from all other Tasmanian forms.
