T. scalarina, T. YorJcensis, and T. Brazieri, the last three of 

 Dr. James Cox. These are all Australian, and, as I believe, 

 varieties of one species. I, however, mark the Tasmanian 

 variety as above for future investigators. 



Tenagodus weldii. n.s. T. t. volubilis laxa, tenuis, alba, dia- 

 phana, nitidula, Icevigata infime flavescente ; anfractihus circ. 6, 

 oblique s^Millissime striatis; rima in anfracUbus tribxts j^rimis clausis, 

 deinde apertis, marginibus subundxdatis, actitis ; apertura basi emar- 

 (jinata, marginibus irregidaribus, acutis, apice septo liemisphwrico 

 clauso. Long. 12. Diam. apertunje 2 mil. 



T. shell loosely twisted, thin, white diaphanous, somewhat 

 shining, smooth, yellow below; whorls about 6, obliquely 

 finely striate ; cleft, closed in the three first whorls, then open 

 with subundulating acute margins, aperture emarginate at the 

 base, margins acute, irregular, apex closed with a hemispherical 

 sejDtum. 



East Coast, somewhat common. A thin very small shell, 

 closely rolled together at the apex, and then rapidly unfolding. 

 It differs from the T. Austrnlis, not only in its very much 

 smaller size, but also in the slit being entirely open without 

 any small rounded foramina in the upper part. I have dedi- 

 cated this interesting species to His Excellency the Governor, 

 F. A. Weld, Esq., C.M.G. It may be a variety of Thylacodes 

 decussatiis, Gmel., but that is much larger, and of delicate rose 

 color.

Long Bay. A unique specimen of a very minute, very
