MALACOLOGICAL NOTES/ 



Va- E. R. SVKES, B.A., F.L.S. 



6.— On a new species of Helieina from Kang-ean Island. 

 Helieina rollei, n. sp. 



T. depresso-conica, soliduiscula, leviter lineis incrementi notata, 

 aurantiaca vel straminea, apice acuto ; anfr. 5 planiusculi, ultimus 

 valde carinatus, antice non descendens ; apertura obliqua, angulato- 

 ovalis ; columella brevis, excavata, basi extrorsum valde angulaia ; 

 peristoma crassiiis culum undique reflexum ; callus basalis tenuis. 

 Operculum non vidi. 



Diam. max. i5"5; alt. 6"5 millim. 



Hah. — Kangean Island, north of Bali (comm. H. Rolle). 



Fig. I. — Helieina rollei, n. sp. 



This interesting shell recalls in form and colour, H. amaliae, 

 Kobelt. It is however much more depressed, the spire much more 

 pointed, the lip is much more reflexed and the denticle at the base 

 of the columella more marked. In this last respect it resembles //. 

 ariglutinans, Sby., but here again the lip is in //. rollei much more 

 expanded and reflexed and the upper margin does not descend in 

 front. 



7.— The value of the name Ctenopoma. 



The name Ctcnoponm was first used in a generic sense by Peters 

 in 1844 (SB. Ak. Berlin, 1844, p. 34) for an African fish. Subsequent 

 reference to it in Ichthyology may be found so far back as 1855 in 



See ante, p. 20.
