650 MESSRS. NEWTOIS^ AND TEALL ON [NoV. 189S, 



ii'ew (PL XXIX, figs. 4 & 5). These two fossils were found in one 

 piece of matrix, hard frozen, but Dr. Kcettlitz says that it was 

 certainl}^ in situ. 



The lamellibranch is a large loioceramus-like shell, about 8 inches 

 long and 5 inches wide in its present imperfect condition. It has 

 a great resemblance to the Cretaceous Inoceramus Cuvieri. The 

 margins of the shell have been destroyed, and the outline is therefore 

 unknown, but, judging from the direction of the eight or nine strong, 

 rounded, wave-like folds, it was oval in shape, narrowing towards the 

 umbo. The hinge being destroyed, its generic affinities are uncertain, 

 but provisionally it is placed in the genus Inoceramus. 



The belemnite is about 3-|- inches long, and tapers very regularly 

 from end to end. The upper part shows the thin edge of the 

 alveolar cavity, and the guard cannot therefore have extended much 

 farther. Sections exposed by cross-fractures show that the cavity 

 was central and extended nearly half way down the specimen, also 

 that the guard is compressed and oval very nearly to the apex : the 

 radiation being as nearly as possible concentric. There is no trace 

 of any flattening or grooving towards the apex. 



This belemnite resembles the B, inornatus of Phillips ^ in its 

 general form ; especially is it like the figure in which the grooves of 

 the apex are wanting ; but the present specimen is more compressed, 

 and there is nothing to show that grooves were ever present at the 

 apex. There is a specimen in the British Museum from the 

 Inferior Oolite, which is referred to the B. sjnnatus of Quenstedt, 

 that is somewhat like our specimen in form and is much com- 

 pressed, but the apex is more slenderly pointed and there are other 

 differences. 



5. West of Elmwood. 



Many new specimens have been collected from this locality, 500 

 yards west of Elmwood, at a height of 30 or 40 feet above the sea, 

 but most of them are too poor to add anything to what has already 

 been said. Among the many pieces of belemnites there are, how- 

 ever, some which show on the broken surfaces excentric radiation of 

 the B. Panderi-type as well as the general form of that species. 



Many fragments of Avicula and pieces of Ostrea have been added 

 to the previous collection, but the former genus is now represented 

 by one or two more perfect specimens. One valve preserved in 

 ironstone is slightly concave, and measures about 3| inches in height 

 and about the same in length (PI. XXIX, fig. 1). The hinge-line 

 is preserved, and is seen to extend as a pointed wing to a greater 

 length than was suggested by the outline in the previously-published 

 plate. This is evidently the same species as the shell there figured, 

 but, being the flattened valve, it has the ornamentation less strongly 

 marked and appears to have been as large as the convex valve.
