(LoC. cit. Vol. 7, p. 139.) TORNATINA APICINA. 



T. minuta cylindracea, elongata, alba, lineis incrementi tenuissimis 

 insculpta, apice mammilato ; anfr. 4, sutura canaliculata. Apertura 

 \ long. testcB, perangusta, plica columellari obsoleta, labro lateraliter 

 viso arcuato- Axis 5 millim., diam. 2. Hob. Sydney Harbour, 

 N. S. Wales. 



The aperture is broader, and the pillar-fold less definite than 

 T. fusiformis. 



[Very questionable if distinct from the last named, and as I 

 think not distinct from T. brenleyii. Angas Zool. Proc. 1877. 

 J. E. T. W.] 



(Loc cit. p. 140.) — Cylichna regtjlaris. 



T. satis magna, elliptica, elongata, alba, spiraliter insculpta, 

 vertice obtuso, late perforato. Apertura perangusta, admodum 

 antice ampliata, columella incrassata, vix incurvata, imperforata, 

 ventre calloso. Axis 9, diam. 4 millim. Hab. Sydney Harbour, 

 N. S. Wales. 



[We have only one Cylichna in N. S.Wales, G. arachis Q. and G., 

 which seems the same as this shell. — J. E. T. W.]

Jissura curta, in canalem internum versus apicem producta. Long. 



12, lat. 8, alt. 7, millim. Hab. Sydney Harbour, N. S. Wales.

 australis, Lamk. J. E. T. W.]

T. ovata, acuminata, solida, lactea, striis confertis transversis,
