Ancient Remains of Emys lutaria in Norfolk, 227 



I can only make a few observations upon them; and these, I may 

 add, have been chiefly brought to my notice by my kind friend 

 Dr. Albert Giinther. 



Of the limbal remains of the two individuals*, I have now 

 before me sixteen bones or fragments of bones, consisting, when 

 fitted together, of one right humerus, one right and one left sca- 

 pula, one right and part of one left clavicle, tivo right and two 

 left femora, one entire pelvis, with two portions of another, and 

 one right and tico left tibiae. From these bones it is plain that 

 the two individuals diff*ered slightly in size. 



Of the vertebral remains in the larger specimen, thirty-six 

 out of the sixty-three bones, or more than half, remain. To 

 specify them, I shall adopt the system of notation employed by 

 Bojanus in his beautiful Monograph of this speciesf. The me- 

 dian or vertebral row of the dorsal bones is the most deficient, 

 only three out of the ten, namely, v, ix, and x, being left. It 

 is very unfortunate that the sixth, seventh, and eighth are lost, 

 as they appear to vary much in different individuals, and I 

 cannot conjecture what shape they may have had here. Of 

 the twenty-four marginal bones, nine are forthcoming; these 

 luckily include xi and xxiii, the nuchal and caudal scutes. 

 The others which have been preserved are xv, xvi, xvii, xviii, 

 xxviii, XXIX, and part of xxxiv. The costal bones on the right 

 side all remain, with the exception of the first false rib, xxxv; 

 on the left side, four of the ten are missing, namely, xlv. xlvi, 

 XLVii, and li. The processes of the tenth false rib on either side, 

 XLiv and liv, remain attached to xliii and liii respectively. 

 The sternal bones of this (the larger) specimen are in a singu- 

 larly perfect state, the posterior process of the left hinge alone 

 being somewhat damaged. Thus it will be seen that the por- 

 tions present are such that the size of the specimen can be 

 pretty correctly ascertained ; and accordingly I give the follow- 

 ing dimensions, which, I am confident, approach the truth very 

 nearly : — 



Entire length of carapace, in a straight line, 7 inches. 



Ditto, following the curve 8*2 „ 



Entire breadth of carapace, in a straight line, 5*5 „ 



Ditto, following the curve 8*6 „ 



Greatest length of plastron 7*5 „ 



Greatest breadth of ditto 4*4 „ 



* I ought to say that I was not aware that the bones were those of two 

 individuals, until the fact was mentioned to me by Prof. Owen, though, 

 in justice to myself, I may add that I despatched them to him immediately 

 on their being entrusted to ray care.
