being figured herewith. It is 4 mm. in major diameter but has 

 five whorls, as is usual in the genus, not four as is ascribed to 

 M. henniana. A microscopic sculpture of fine radial threads 

 over-run the spirals and are more apparent on the base. In 

 colour it is variable, the figured example has walnut-brown 

 radial flames on a grey ground, in others the flames are brick 

 red and in some the flames break up into small chequers. 



Larina C?) turbinata, Gatliff and Gabriel. 



Larina{?) hirbinata, Gatliff and Gabriel, Proc. Roy. Soc. Vict., 

 xxii., (n.s.), 1909, p. 35, pi. xiii. 



Under this title was described a mollusc dredged alive in five 

 fathoms in Western Port, Victoria. The same species was 

 subsequently procured by Mr. W. L. May in fort}' fathoms oflf 

 Schouten Island, Tasmania. ^^ 



Though first described from " Moreton Bay," Mr. E. A. Smith 

 shows that Larina is related to Vivipara and is "undoubtedly a 

 fresh water form. " In rebuttal Messrs Gatliff and Gabriel 

 suggest that tidal influence might prevail in the Mackenzie 

 River, Queensland, at the spot where typical Larina occurred. 

 Unfortunately for this argument the Mackenzie flows not into 

 the sea, l)ut into the Fitzioy more tlian a hundred miles from 

 marine influence. Another species of Larina was discovered by 

 D'Albertis in tlie Upper Fly River, British New Guinea. 



Pictures of the two shells look alike, but actually L. iurbinata 

 has but superficial resemblance to the real Larina. Though 

 destructive criticism of this classification is eas}', constructive 

 work of correctly placing the Victorian shell is liard. With 

 happier treatment the radula and operculum might have directed 

 us to its natuial position. But the operculum was lost, the radula 

 left undescribed and figured as a featureless blur. 



Failing the introduction of a new genus I would suggest for 

 the reception of L. (?) Iurbinata, Pfeff^er's Antarctic genus 

 Pellilitorina.^* To this belong P. serosa, Smitli, from Kerguelen, 

 and F. pellita, Martens, from South Georgia.
