 fossil in N. and S. Italy ; Poland ; Morea ; S. France ; Rhone 

 Basin; near Lisbon; England; Vienna Basin; Azores; Oran, etc.

Genus CARDIUM, Linnseus. 

 Systema Naturae, 10th ed. (1758), p. 678. 

 Type. — G. costatum, Linnseus. 



CARDIUM, sp. (PL IX, Figs. 3, 4.) 

 Remarks. — Under this genus are placed three casts of shells 

 with attached valves, which are tumid, oblique, and elongate, and 

 furnished with incurved, anterior, nearly contiguous umbones, 

 beneath being an oval excavation. One of the specimens is covered 

 with obscure vei'tical ribbing on its left valve, and still more obscure 

 indications of concentric sculpture. An obtuse, postero-median, 

 oblique carination proceeds from the beaks to the ventral region, 

 forming the inner margin of the posterior area. This form appears 

 to be related to Cardium discrepans, Basterot, a species common 

 to the Miocene of Southern France, N. Italy, etc. 



Dimensions. — Height, 45 mm. ; length, 43 mm. ; diameter, 30 mm. 

 Horizon. — Miocene (Tortonian). 



Distribution. — Egypt : Camp 9. Coll, Geol. Surv. Egypt, 

 No. 642, Box No. 53a. 



Genus LTJCINA, Lamarck. 

 Mem. Soc. Hist. Nat. Paris, 1799, p. 84. 

 Type. — Venus edeniula, Linnseus. 



LUCINA MULTILAMELLATA ?, Deshayes. (PL VIII, Fig. 7.) 

 ^ucina multilamellata, Deshayes : Encyclopedie Methodique, voL ii (1830), p. 377 

 (not figured). Hoernes, " Foss. MolL Tert.-Beck. Wien" : AbhandL k. k. 

 geol. Eeichs., voL iv (1864), p. 227, pi. xxxiii, fig. 2. Fuchs: Palaeonto- 

 graphica, vol. xxx (1883), p. 39 (21), pi. vi (i), fig. 12. 



Description. — The Egyptian collection contains a series of casts 

 belonging to a lenticular and suborbicular shell with both valves 

 in contact, which resembles very strongly Fuchs' interpretation of 

 this species as figured by him in the Falcsontographica. The 

 surface irregularities on the interior of the valves, alluded to by 

 Deshayes in the original description, are well seen in the specimens, 

 besides some obscure indications of radial striae. 



Dimensions. — Height, 62 mm. ; length, 54 mm. ; diameter, 24 mm. 



Horizon. —Miocene (Helvetian). 



Distribution. — Bordeaux; Vienna Basin. Egypt: Siwa (Fuchs); 

 between Camps 19 and 22 (2c) and S.E. of Camp 19 (48c). Coll.
