two cardinal teeth in each valve, Montrouziera has in the right 

 valve a third cardinal additional, and posterior to the otliers. 



Clanculus comarilis, sp. nov. 

 (Plate xl., figs. 9, 10, 11). 



Shell solid, conical. Whorls, seven, parted by impressed sutures. 

 Colour, white, clouded with pale brown, every third or fourth 

 bead in every row picked out with dark madder-brown, giving a 

 general effect of irregular dark radial stripes on a pale ground. 

 Apex articulated with crimson. Sculpture : on the upper whorls 

 are four gemmule rows, and part of a fifth is visible along the 

 suture, the last whorl has twelve rows, of which seven are on the 

 base. The gemmules are prominent, glossy, about fifty to a 

 whorl, their breadth apart from row to row, but closer within 

 the row. The anterior row of each whorl lias larger and more 

 crowded gemmules. The interstices between tlie rows are 

 microscopically reticulated by spiral and oblique strife. Tlie 

 aperture descends two gemmule rows. Within the liase are tour 

 entering plications, otherwise the armature agrees with that of 

 C. unedo and related forms. Heiglit, 13; maj. diam., 10; min. 

 diam., 8 mm. 



The novelty is perhaps nearest to Clancuhis vnedo, A. Adams' *', 

 a species already reported from Australia by Messrs. Melvill and 

 Standen'^. Adams' name is without locality or size and was in 

 literature unrecognisable until Fischer'- figured and redescribed 

 it from New Caledonia. C. comarilis is distinguishable from the 

 New Caledonian species by its narrower form and its colour both 

 of hue and pattern. C. unedo has more ridges within the outer 

 lip than G . comarilis. By its narrow elevated shape the no\elty 

 concludes a sequence from 6'. clanguloides to C. stigmariits to 

 C. unedo.
