which emerge at the surface in large rounded bosses. Another 

 feature of this species is the expansion of the median layer 

 towards the edge of the test. Previously descriVjeJ only from 

 Iriomote Island, Riu-Kiu (Loo Choo Islands). 



We have a fine series of 'this interesting Lejndocyclina in the 

 sections of the Malekula Miocene limestones. It occurs both at 

 Laleppe and Bartaleppe.

This species has been previously described by the abo\e-named 

 authors, from the upper part of the Aquitanian of the I. di 

 Malo (Vicentin). As Lemoine and Douville have already 

 pointed out, it may be readily distinguished from L. angularis 

 by its external form; otherwise in certain respects they seem to 

 be allied. 



L. munieri occurred in the Malekula limestone at Bartaleppe. 



Lepidocyclina andrewsiana Jones & Chapman. (PI. xxxix., 



fig. 10). 



Prof. Silvestri in writing recently upon the variant forms of 

 the type Leiiidocyclina dihUata Michelotti sp."^ has included the 

 above species in the synonymy of Lemoine and Douville's L. 

 tournoueri.-] Should the two forms be proved identical, the 

 earlier name L. andrewsiana is the one to retain. For the 

 present, however, I am content to regard the two forms as 

 distinct, since L. aiidrewsiana possesses very solid divergent pillars 

 seen in vertical section, whilst the entire structure of the shell is 

 more compactly built than in L. tournoueri. In the latter, more- 

 over, the swollen central area is less pronounced and more 

 irregular in contour, L. andrewsiana being practically sub-
