226 THE PnOCEEDINGS OF THE LINNEAN SOCIETY 



Pleurotoma samdeli. pi. 20, fig. 3. 



P.t. elongato-fusifomi, parva, tenui, polita ; an jr. 6, declivihus, 

 in medio angulatis, nodosis et undulose striatis ; nodis elevatis 

 suhquadraiis, ultimo anfr. spiraliter striata et longitud. fiexuose 

 corrugate ; apertura^ angusta, elongata ; lahro acuta tenui, sinu 

 laio 'profunda, canali longa, parum recurva, sutura profunda. 

 Long. 12, lafc. 4, long, spirae 7. 



This very eleganf, species is very like P. dimidiata of the Paris 

 basin and Vienna miocene, but it is smaller and the spiral lira? at 

 the base are distant. It is a polished shell with whorls angular 

 in the middle supporting a single somewhat distant series of 

 coarse blunt somewhat square tubercles. These are exactly on 

 the line of the sinus, and at each side the lines of growth curve 

 away from it. The sinus itself is deep broad and somewhat 

 quadrate. The aperture is long and round rather square 

 posteriorly and the canal is long and only slightly curved. 



I have named the shell after the christian name of Mr. S. P. 

 Winter, from whom I have received so much assistance in getting 

 fossils from these beds. 



Daphnella geacillima, mihi (Sec. Proc. Roy. Soc. Tas. 1876, 



p. 106). 



PI. 20, fig. 10 is a representation of a much worn specimen of 

 this fossil, which is very common at Muddy Creek. The specimens 

 found there are much more solid and thick than those of Table 

 Cape, Tasmania, and the spiral groove less distinct.

 gata, angusta, canali prceJango, recto; hasi concava, lirata ; et

 columella en catista, labia exacte definito. Long. 17, latG; long

This neat little species is distinguished by its long canal and 

 pyramidal spire. The whorls are flattened, but have three
