This species is a smaller white variety of A. onarginata, Lam., 

 at least so it appears to me, for the forms closely resemble 

 each other. In Sowerby's Thes. Con. Aucil., pi. 3, fig. 47, the 

 above variety appears to be figured. King's Island, Bass' 

 Strait, and Circular Head. W. F. Petterd.

A somewhat turretted, very closely ribbed shell with fine 

 spiral striae very distinct in the interstices, of yellow color and 

 light brown cloudy spots. It has only as yet been found at 

 Eagle Hawk Neck, and was placed in my hands by Mr. W. 

 Legrand.

This shell so closely resen)bles my P. littorinoides, that no 

 better description can be given than to say that it is broader, 

 shorter, with fewer whorls, and the spiral lirae become six 

 stout corrugated ribs with a corrugated one at the angle. 

 The aperture is fulvous. It is intermediate between the species 

 just mentioned, and Mr. Angas's P. flindersii of Spencer's 

 Gulf, South Australia. The difterenee may be due to climate. 

 I am not aware if P. littorinoides is found on the N. coast. 

 Future observers must solve the question of the specific dis- 

 tinction of these throe shells which are different enough at 

 their various stations, many hundred miles apart, but may
