1865. ] AND FLUVIATILE MOLLUSCA OF PALESTINE. 537 
59. Buxtimus LABRosus, Oliv. 
The finest and most characteristic shell of Palestine. It is found, 
generally concealed in small fissures of the limestone rocks, some- 
times under stones, throughout the whole of Western Palestine, as 
far as the edge of the Ghor or Jordan valley, but not beyond. 
It is most abundant near the coast, where it attains its greatest size. 
A very small variety is found in the southern wilderness. 
60. Butimus cARNEUs, Pfr. 
This beautiful shell takes the place of the preceding species in the 
basin of the Dead Sea towards the south; but we never found it 
north of Engedi, nor on the east side. It is most plentiful about 
the famed rock of Masada, the modern Sebbeh. We brought a con- 
siderable number home alive, which are now depositing their eggs, 
and feeding on succulent plants. It is impossible, after observing a 
large series, to have any hesitation in separating B. carneus specifi- 
cally from B. labrosus. The elongated form, the mouth proportion- 
ally less than half the size of the other species, and circular instead 
of being extended towards the right, the solidity of the peristome, and 
the callosity largely extended over the last whorl at once distinguish 
every specimen; nor have I ever detected any intermediate forms. 
The typical B. carneus of Dr. Pfeiffer is from Lycia. I have not 
been able to compare my specimens with the type, though they ap- 
pear to coincide exactly with the diagnosis and the figure. It is 
possible that our Dead Sea species may be distinct. 
61. BuLimus HALEPENSIS, Pfr. 
Generally diffused, but scarce in number of individuals. Collected 
near Jerusalem and by the Dead Sea. 
62. Butimus syriacus, Pfr. 
Extremely abundant in certain localities of the Lebanon. 
63. Buitimus s1pontiEnsis, Charp. 
In the plain of Pheenicia and the neighbouring hills. 
64. BuLimus ATrENvATUS, Mouss. 
Erroneously identified by Bourguinat with B. obesatus, Webb and 
Berthelot, from the Canaries. Frequent throughout the wooded 
hills and under brushwood in Western Palestine. The rich olive- 
green epidermis of the living shell seems to have escaped the notice 
of its describers. 
65. BULIMUS URIA, Nn. sp. 
T. cylindracea, ventricosa, oblique arguteque striolata, nitidius- 
eula, corneo-olivacea vel cornea; anfract. 7, plano-convecis, 
ultimo anfractu dimidium longitudinis vix aquante; apertura 
obliqua, rotundata, contracta ; peristomate albo, intus labiato, 
reflexo ; margine columellari vix dilatato. 
Long. tota 15, lat. 7; apert. long. 53, lat. 43 mill. 
Hab. The Wady of Amman (Rabbath Ammon).
