GEOGRAPHICAL DISTRIBUTION. 
Moll. 27 
Locard, Arch. Mus. Lyon, iii. pp. 195-293, pis. xix.B-xxiii. In the Lake 
of Tiberias, the genera Unio , Gorbicula , Melania (tuberculata), Mela- 
nopsis , and Theodoxia [ Neritina ], are represented ; in that of Antioch, 
beyond the same, except Melania , also Legumincea , Pseudodon , Anodonta, 
Dreissena , Planorbis, and Limncea ; in that of Homs, only t7rao, Legu- 
minaia , Gorbicula , Melanopsis, and Limncea. The species of £7m'o belong 
partly to the group of U. litoralis , partly to that of terminalis (Bourg.), 
The species of Limncea are nearly similar to the European, viz., to L. 
stagnalis, ovata , peregra ; one, from the Lake of Homs, is even admitted 
by the author as the European L. lagotis. Corbicula syriaca , sp. n., and 
Melanopsis costata (Oliv.), are common to all three lakes ; some species 
of Unionulce , Melanopsis , and Neritina michoni , to two of them. The 
author gives, pp. 201-203, a list of all known and some undescribed 
species of Melanopsis , hitherto found in the Turkish part of Asia (25 
in jill). 
Cyrenaica ( Bengazi ). 12 terrestrial species (1 new) collected by 
G. Ruhmer, of which 8 are hitherto known on the northern coasts of the 
Mediterranean, 2 more westwards, and others more eastwards on its 
southern shore ; E. v. Martens, SB. nat. Fr. 1883, pp. 147-149. 
7. Africa. 
Abyssinia. J. R. Bourguignat describes the shells collected by 
Achille Raffray in 1881, chiefly in the table-lands of Hamacen and 
Anderta, and on the mounts of Zebul and Abuna Yusef , at heights of 
2000-3000 metres, and adds a general and very critical review of all land 
and fresh-water shells of Abyssinia, amounting to 167 species, with enu- 
meration of their literature, and a general sketch of the physical 
conditions of the land. In several species of Bulimus [ Buliminus'] he 
finds some resemblance to the American species of the Andes [ Bulimulus ], 
due probably to a certain similarity of the climate. Only a few species 
of more general distribution'^ are found, as, for example, Opeas gracilis 
and Limncea truncatula. The author divides Africa into four zoogeogra- 
phical regions : — (1) African centre, from the south of the desert to the 
twentieth degree of southern latitude ; (2) Natalie centre, south of the 
preceding to the Cape of Good Hope ; (3) Malgache centre, Madagascar, 
with radiations to the east coast of Africa and the south coast of 
Arabia ; (4) Asiatico-European centre, north of the desert and both 
shores of the Red Sea. Ann. Sci. Nat. (6) xv. Nos. 1-4, 162 pp., 4 pis. 
and map. 
Guinea. Some new terrestrial species, with a new genus of slugs, 
Aspidelus ; Morelet, J. de Conch, xxxi. pp. 395-401, pi. x. 10 terrestrial 
and 1 fresh-water species from Landana, mouth of the Congo ; Craven, 
Ann. Soc. mal. Relg. xxvii. pp. 18 & 19. 
Southern Tributaries of the Congo. 1 terrestrial and 4 fresh-water 
species collected in the Lualaba and neighbouring rivers by Lieut. Wiss- 
mann, none of the latter identical with Tanganyika species, 2 new ; E. v. 
Martens, SB. nat. Fr. 1883, pp. 72-74.
