THE LAND MOLLCJSCAN FAUNA OF BRITISH NEW 



GUINEA. 



(Anatomical Supplement, continued from p . 115.) 

 By C. Hedley, F.L.S. 



(Plates xxxviii.-xlii.) 



Nanina hunsteini, Smith. 



Jaw (pi. xxxviii., fig. 1) arched, smooth, with a slight median 

 projection inferiorly, emarginate superiorly, ends rounded. 



Radula (pi. xxxix., fig. 11) strap-shaped, three times as long as 

 broad ; formula 160 rows of 90 : 20 : 1 : 20 : 90 ; rows nearly 

 straight, somewhat bracket-shaped ; rachidian twice as long as 

 broad, tapering to a single rather blunt cusp which just projects 

 beyond the basal plate ; laterals scarcely larger than the rachidian 

 and of the same construction, angle of basal plate scarcely expanded, 

 the more distant laterals grow slenderer and more inclined ; two 

 or three transition teeth intervene between the latter and the 

 marginals, which are sinuate and bicuspidate. In the figure, the 

 marginal teeth should be transferred^ from the right to the left of 

 the centrals. 



I lately hazarded a conjecture (Records Aus. Museum, Vol. i.,

 dentition here described does not support this view. 



Genitalia (pi. xlii., fig. 39), penis sac long and cylindrical, with 

 a globose sessile sac seated half way along it and another smaller
