of Flammulina and Endodonta, for the latter is also necessary 

 through the acceptance of the spirally striated nuclear whorls as 

 characteristic of Allodiscus, considered as a sub-genus of Flamnmlina. 

 In the following cases I refer one species to Calymna on account of 

 its effstulate appearance, whilst the other I simply call Flammulina, 

 sensH lata, as ray studies have not yet enabled me to place it. Wlien 

 Suter (loc. cit.) gave his experience with regard to the examination 

 of Tasraanian molluscs, he concluded that the majority of Tasmanian 

 ' Flammulints' belonged to Gerontia, but I note that Cox and Hedley 

 have replaced some of these in Fndodonta, where, judging from shell 

 characters, they seem more happily located. Endodonta, however, 

 seems, as regards species with armed aperture, very rare in Australia, 

 whilst it also appears doubtful whether typical Charopa has yet been 

 recorded. The delimitation of genera would certainly make these 

 points more obvious. 



Flammulina miserabilis, n.sp. Fl. XVIII, Fig. 4. 



Shell minute, thin, sub-conical, spire slightly elevated, sutures deep, 

 umbilicus narrow. Colour uniformly pale-brownish fawn. Whorls Z\ ; 

 first whorl and a lialf finely spirallj' striated ; succeeding whorls 

 sculptured with fine radial striae, and between the striae closely set 

 spiral scratchings. Aperture obliquely lunate, lip thin, sharp. 

 Umbilicus deep and narrow, about one-fifth the diameter of tlie shell. 

 Diam. max. 15, min. 1-25 ram. ; alt. '8 mm.

 covered trunks of trees. 



Caltmna arboricola, n.sp. PI. XVIII, Fig. 3. 



Shell small, sub-discoidal, thin, fragile, umbilicus narrow. Whorls 

 3f, somewhat rapidly increasing, sutures well marked. Colour pale 

 fawn with darker red-brown flammulate markings. Sculpture : first 

 whorl and a half, constituting the protoconch, finely spirally striated; 

 the succeeding 2^ whorls radially sculptured with closely set, low, 

 eveidy spaced riblets, about eighty being counted on the first adult 

 whori, minute threads intervening between each ; on the following 

 whorl the riblets and threads become almost inseparable, and about 

 one hundred major riblets can be noted in most specimens, with two 

 or three minor ones clearly marked between and almost as prominent ; 

 in some sliells the major ones disappear on the last quarter whorl, and 

 this consequently appears smoother in comparison. Apeiture oblique, 

 somewhat lunate ovate, columella refiected. Base rounded, umbilicus 

 deep and narrow, about one-sixth the diameter of the shell. Diam. 

 max. 26, min. 22 mm. ; alt. l-2o mm.

Helix Chimmoi, Pfeiffer. 



In the Proc. Zool. Soc. Lond., 1856, Pfeiffer described two shells 



supposed to have come from Sunday Island, Kermandec [.s/c] Group. 



The first (]). 326) was called Helix Kennandeci. and has since been 



recognized from Sunday Island. The other was called //. Cliiiinnoi,
