MARINE MOLLUSCA OF MADEIRA. 235 



mouth, it sweeps widely and freely away to the right. Outer 

 lip : it rises in the young shell barely perceptibly (in the older 

 shell, uot at all) above the apex, with very little of an advancing 

 edge, and forming no sinus it turns at an obtuse angle and 

 advances a little obliquely but in a straight direction to the 

 periphery, from which, neither contracted nor expanded but 

 retaining its forward edge, it slopes slightly backwards, and then 

 makes a great patulous sweep round the base out to the left of 

 the pillar, from the tip of which, with a free circular sweep, its 

 sharp edge bends round to join the body, leaving behind it a 

 narrow groove and an open-mouthed, but minute, umbilical 

 depression, above which to the apex the mouth-edge is defined by 

 a broadish-spread, thin, whity film.— H. 0133. B. 0-13. 



Prom Punchal Bay along the S. coast eastward to Punta Sao 

 Louivnco down to 50 fms. ; rare. Mr, Johnson got one speci- 

 men ; I several, but chiefly young. It resembles A. globosa, Lov., 

 but differs in colour, in smaller body, in larger opener mouth, in 

 flatter top, and in sunken apex.

Gen. Philine, Asc. 



3. Philine complanata, n. sp. 



Shell thin, tumid, smooth, a little oblique in form, and with a 

 flattened top. Sculpture: rather feeble, close, irregular lines of 

 growth. Colour pure white, translucent, not glossy. Spire 

 tabulated, nucleus slightly impressed, but the rest of the spire 

 becomes gradually a very little prominent. Whorls two and a 

 half, with a small mammillary nucleus. Mouth pear-shaped. Outer 

 lip open : it springs from slightly below the top edge, advancing 

 a very little, it curves at the top freely round and then runs 

 downward straight, but in its direction a little obliquely towards 

 the right ; across the base it sweeps with a free curve, is a little 

 patulous, and on the left rises to join the point of the pillar, 

 which is barely if at all prominent. Inner lip more or less 

 curved ; it runs a little obliquely but in a line of increasing 

 straightness, carrying the thin glaze spread on the body across to 

 the sharp-edged curved pillar, leaving behind it a minute chink 

 and a mere suggestion of an umbilicus. — L. 0*1. B. - 067.
