Terehratula squammosa, Mant. These four species are very common 



in the Chalk Marl at Blanez and Neufchatel. 

 Terehratula biplicata, Sow. Occurs in the Glauconitic bed above the 



Gault; Blanez. 

 Terehratula snlcifera, Morris. Seems to be very scarce ; T know 



only two specimens which Prof. Gosselet has had the kindness to 



send me ; Blanez. 

 Terehratula semiglohosa, Sow. 

 Bhynchonella Martini, Mant. 

 BhyncJionella Grasiana, D'Orb. 

 Bhynchonella Mantelliana, Sow. These four species are very common 



in the Chalk Marl at Blanez and Neufchatel.

(PLATE XII.) 



THE late Dr. Falconer figured in the "Fauna Antiqua Sivalensis," 

 a fine lower jaw of an adult Elephas primigenius, preserved in 

 the National Collection, and of which he gives two views, the first 

 as seen from above, the second a side view ; and in the descriptions 

 of the plates in the above work given in his " Palseontological 

 Memoirs," vol. i. p. 439, occurs the following note regarding it : 

 " Plate xiii. A. fig. 3. — E. primigenius. English fossil specimen, 

 •with two last true molars on either side. In the last left molar there 

 are eighteen plates in 7*7 inches. The jaw has a short beak, and 

 one inner mentary foramen on either side. In this, as in figs. 1 and 

 2, representing the jaw at dijfferent ages, it is to be noted that the 

 opposite lines of molars are more or less convergent instead of being 

 parallel, or nearly so, as laid down by Cuvier. 



" Extreme length of jaw, 23-6 in. Divergence of rami behind, 

 21'3 in. Height at alveolus, 7*2 in. Greatest width of jaw, 6-3 in. 

 Breadth of condyle, 10-3 in., width of last molar, 2-8 in." 



To the above description may be added, that although the ascend- 

 ing rami are well preserved, the condyles and coronoids on each 

 side are wanting. 



Besides the fact tbat it is a dredged specimen, which is evident 

 from the marine exuviae still adhering to it, and that Dr. Falconer 

 had selected it for illustration as a type of the mandible of a mature 

 adult animal of the above species, not anything was known respect- 

 ing its history, or whence it came, by the present officials of the 

 Palseontological Department ; nor beyond the statement that it is an 

 " English fossil specimen" does Dr. Falconer throw any light upon 

 its history, if he ever knew it. But some time ago, looking through 

 a volume of the " Magazine of Natural History," edited by Mr. 

 Edward Charlesworth, F.G.S., I found a woodcut of the fossil, and 

 a short notice regarding it by the editor, both of which we here 

 reproduce.
