This seems to be the other extreme of the P. Tayloriana series. It 

 is distinguished by its higher spire, the almost entirely flat whorls, 

 the paler colour, the almost vertical deflexion of the end of the last 

 whorl, besides which it has half a whorl more.

My examples agree perfectly with the description of P. Maclaymia, 

 Braz., but on the other hand they differ from P. Tomasinelliana, Tapp.- 

 Can., only by the more depressed spire, the less distinct bands, and 

 slightly more expanded lip. Brazier gives diam. 39, alt. 27 mm. My 

 specimens measure as follows : — 



Diam. 39, alt. 26 mm. 



,, 39, ,, 25 ,, 



,, 38, ,, 26*5 ,, 



,, 38, ,, 27 ,, 



„ 36, „ 26 ,, 



The dimensions of P. Tomasinelliana as given by Tapparone-Canefri 

 are : diam. 36, alt. 23 mm. ; the latter probably taken from the 

 umbilicus, as the figure ^ shows 36x27 mm. I think it is quite 

 sufficient to separate P. Maclayana as a variety only, 



I fail to see the reason why Pilsbry has rejected the well-defined 

 section Insularia, Tapp.-Can., which seems to me a very natural and 

 easily distinguished group, equally as well characterized as Dendro- 

 trochus, Pilsbry. It would be convenient to divide the remaining 

 species of Papuina also into sections, with separate names, such as 

 Rhynchotrochus, for the group of P. Tayloriana.
