440 M. A. C. Hinton — A Monkey' s Bone from the Forest-Bed. 



The genus Haliserites is also represented in our Victoiian Upper 

 Devonian micaceous shaly rocks, where it is associated with Sphenopteris 

 {Eremopteris) igiianensis, McCoy, Archceopteris Howitti, McCoy, and 

 Cordaites australis, McCoy. The examples there met with are, 

 however, too fragmentary to admit of a closer determination than that 

 of the genus.

(PLATE XXIII, Figs. 1-3.) 



rilHE Upper Freshwater division of the Norfolk Forest-Bed Series at 

 \_ West Runton contains two distinct horizons, viz., a lower, con- 

 sisting of a rather thick deposit of clay and peat, and an upper, 

 containing a thin seam of gravelly sand, crowded with land and fresh- 

 water shells, on which reposes the pebble-bed found at the base of the 

 ' Leda-myaUs ' series. My friend Mr. G. White and I have lately 

 collected extensively from the West Runton deposits, and have been 

 rewarded with the discovery of several hitherto unknown voles, etc., 

 which I hope to describe ere long. On comparing the voles from the 

 lower series with those from the upper part of the Upper Freshwater 

 bed one finds considerable differences between them, and I believe 

 that similar differences are shown by the mollusca from the two 

 horizons. These faunistic differences are of course not so great as 

 those which have been shown by Dr. Forsyth Major to exist between 

 the East Runton deposit and the West Runton series taken as a whole, 

 but still they are similar in kind. 



Mr. White has been so fortunate as to obtain, from the thin bed of 

 gravelly sand at West Runton above mentioned, a most interesting 

 bone, which he has kindly permitted me to study and describe in this 

 note. The specimen is the distal end of a left humerus, and in the 

 drawings which I have made (PI. XXIII, Figs. 1-3) it is represented 

 as seen in three positions. Viewed from the front (Fig. 1) the trochlea 

 is prominent, and the capitulumfor the radius is rather boldly convex. 

 Between the two is seen a little rounded ridge, which, passing back- 

 wards and obliquely outwards round the articulation (Fig. 2), dies out 

 before reaching the posterior surface (Fig. 3). This little ridge appears 

 to be very characteristic of the humerus in Primates, and its function 

 is to play externally into a groove on the inner side of the head of the
