Platberg (see the Section, Fig. 1). This is a part of the Drakens-

 Free-State. This Estlieria was found by Mr. David Draper T.h.h., 

 of Lennoxville, Natal ; and is here named after him. It is deposited 

 in the British Museum (Natural History).

 Size : Length of valve, 2^ mm. Length of hinge-line, 2 mm. Height, l^ mm. 



On the piece of shale bearing BstUria Draperi (Fig 1) are two 

 very small flattened Estherian valves, one of which is shown, much 

 enlarged bv Fig 2. Their shape is different from that of the larger 

 form, being sub-elliptical, much less oblong, relatively higher and 

 more boldly curved at one end, and elliptically curved on the ventral 

 border ; with the umbo nearer to the narrow than to the broader 

 (higher) end of the valve. 



It is unusual for the umbones, and consequently the anterior part 

 of the body, to be nearer to the smaller than to the larger end of 

 the valves. This condition is seen in some varieties of K striata 

 (Monog. Foss. Estherife, 1862, pi. i. H^-l}' 13, and 15), in 

 k Dawsoni (Geol. Mag. 1870, PI. IX. Fig. 15), and m E tenella 

 var. (ibid. Fig. 16); but their umbones are much further forward 

 than in our Fig. 2, where it is not far in front of the middle of the 

 hinge-line. The form nearest to our Fig. 2, in this submedian
