1870. ] MR. G. B. SOWERBY ON NEW SHELLS. 253

This shell differs from P. oxytropis in being laterally much more 
compressed, in being much shorter above the keel, which is sharp 
and white, and in being altogether more closely sculptured.

viridi induta; spira mucronata, convexiuscula, aperturam longitudine 
superante ; anfraciibus declivibus, medio concavis uniliratis, supra
