FROM THE MEDITERRANEAN AT JAFFA. 197 



on the upper volutions, the two central ones being most conspicuous, and 

 at the points of contact with the costse produce a nodulous appearance. 

 The two others, which are much less distinct, and in some specimens 

 almost obsolete, are situated above and below at the suture. The body- 

 whorl has about eight Hrae dotted with dark brown, and a conspicuous 

 white oblique varix on the left side opposite the labrum, near which it 

 ascends slightly. The aperture is small, ovate, white, exhibiting the 

 external dotting some distance from the margin, and terminates in a very 

 short oblique canal beneath. The columella is incurved at the middle, 

 covered with a thin callosity, and bears at the upper part a fine transverse 

 lirae running some distance within the aperture. The labrum is white, 

 thickened exteriorly, and finely lirate within. 



Length 12 millim., diam. 4^, aperture 3f long, 2 wide. 



This species has been kindly examined by the Marquis Monterosata, 

 to whom it is unknown as a Mediterranean form, and there does not 

 appear to be any species from that region sufficiently resembling it with 

 which a comparison can be made. 



Besides the black dots already mentioned, other paler specks are dis- 

 cernible under a lens, irregularly scattered over the surface.

The above species have been, except where otherwise stated, deter- 

 mined by Mr. G. B. Sovverby, of Russell Street, London. I am deeply 

 indebted to Mr. Edgar Smith, o( the British Museum, for examining 

 several critical species, and for giving me references to several of the 

 works which I have made use of. Of these the earliest and most
