 maximus having been an immense vultuiine bird — the " Roc " of 

 Marco Polo. 



H. B. Geinitz on the Ceetaceous Inocebami. — In working out 

 the Inocerami for his work on the Geology of the Elbe Valley in 

 Saxony, Prof. Geinitz has had to study these shells very closely. 

 He reduces the species to eleven ; and, commencing with Inoceramuf 

 concentricus, Sowerby, of the Gault (which points with others, he 

 thinks, to a Liassic origin), he passes to I. striatiis, Mantell, of the 

 Cenomian stage (Lower Quader and Lower Planer). This species 

 gives off, as it were, in the same stage, I. latus, Mantell, which 

 becomes in the next (Turonian or Middle Quader, Middle Planer, 

 and Planer limestone) I. lahiatus, Schl., and I. Cuvieri, Sow.; 

 whilst the Turonian I. Brongniarti, Sow., is another branch, and 

 I. striatoconcentricus, Gtimbel, of the same stage, is in the straight 

 line of development. In the Senonian, or Upper Quader and Upper 

 Chalk, /. planus, Miinster, and /. Cripsi, Mantell, continue from the 

 Cuvieri-hranch.; and /. Lamarcki, Park., from the parallel Brongniarti- 

 branch ; and all point towards the highest, namely, /. involutus, Sow, 



Some Gigantic Fossil Mammals. — Among the huge fossil mam- 

 mals obtained from the Lower Tertiary beds of Wyoming, the 

 Dinocerata, Marsh, are very remarkable. The long narrow cranium 

 bears three pairs of horn-cores, rising one pair above another, from 

 the low nasal pair, to the higher conical maxillary pair, and to the 

 posterior highest and broadest pair, which may have borne expanded 

 and possibly branching antlers. These last horn-cores slope down 

 in front into a pair of lateral coronal ridges, dominating over the 

 great temporal fossge. The attenuated nasal bones overlap a deep 

 narial cavity. The premaxillaries are slender and toothless. In 

 each maxillary is a great canine tooth, long, sharp, and decurved, 

 with their roots running up into the middle horn-cores. Six small 

 premolar and molar teeth on either side, with transversely ridged • 

 crowns, form another peculiar feature in this wonderful beast. 

 Already various specimens, representing parts of the skeleton of 

 several species of this genus, appear to have received different 

 generic names — as Loxolophodon, Cope ; JJintatherium andUinfamastrix, 

 Leidy ; Dinocera, Marsh ; ^obasileus, Cope. Of their relative claims 

 to priority and use, Prof. Marsh treats in the illustrated reprint 

 before us, from " Americ. Journ. So." for Feb., 1873, p. 117, pub- 

 lished in advance Jan. 28, 1873. 



In his Anniversary Address to the Eoyal Society of New South 

 Wales, May 22nd, 1872, the Rev. W. B. Clarke, M.A., F.G.S, etc., 

 gives a valuable summary of facts and opinions relating to the 

 natural history of the diamond and diamond fields in Brazil, South 

 Africa, India, and Australia, in amplification of the very useful 

 observations he offered on the same subject in his Anniversary 

 Address of May 25th, 1870 (1871). T. E. J.
