394 Mr. J. Miers on the Styraceae, 



provided with only six whorls, by th^ absence of any .angle at 

 the periphery, its greater solidity, larger perforation, more con- 

 vex whorls, more slender spire, and by the greater obliquity of 

 the stria tion. The aperture is not quite perfect ; and the shell 

 has evidently been buried in a ferruginous soil, with the colour 

 of which it has become stained. 



M. Albert Mousson, in a Memoir on Professor Bellardi's 

 shells, notices B. acutus as found at Sayd, as well as Pupa Gra- 

 num, which had not previously been observed so far to the east- 

 ward. A dead specimen or two of the latter shell, found by 

 Ml*. Atkinson in the sand of the Brook Kedron, near Marsabba, 

 accompanied B. Benjamiticus, and, not having been previously 

 noticed in the vicinity of Jerusalem, was supposed to be a new 

 species. Like the shell taken by myself in Provence, and the 

 specimens which occur near Villa Franca, in the neighbourhood of 

 Nice, it possesses a parietal tubercle at the angle of the insertion 

 of the outer lip, — a feature omitted in the characters contained 

 in the 2nd volume of Dr. Pfeiffer's Monograph, where only seven 

 teeth and plicae are assigned to the aperture. 



The discovery of these two shells near Jerusalem in a living 

 state, will be necessary to prove that they are not subfossil relics 

 of a past sera. They are discoveries of a more recent date than 

 the publication, in 1855, of Dr. Roth's ' Spicilegium.'

4. Pamphilia. 



This genus scarcely differs from Strigilia, the principal point 

 of distinction being the suppression of one-half of its stamens, 

 which are only five in number, and alternate with the petals ; 

 they are only two-thirds the length of the petals, and the anthers 

 are one-third the length of the filaments : these last are mem- 

 branaceous, broad, nearly double the breadth of the adnate 

 anther-cells, forming an expanded thin border round the sides 

 and apex of the anthers. The anthers are sometimes deficient of 

 pollen, in which case they cohere slightly by their margins into 

 a tube, from the bottom of the anthers to the base ; but when 

 polliniferous, they are distinct and free, a character of frequent 

 occurrence in Strigilia : they are glabrous, except along a dorsal 

 median nerve, which is stellately pilose. The ovary is depressed 

 and turbinate, corresponding in its internal structure with that
