UPPER TRIAS, 
L. Ramsaneri of Hauer lias too many ribes, and Pecten ? 
Puchsi of Hornes is too flat, and has, besides, a different shape. 
I would name the Himalayan species, if it were more perfect. 
EXOGYRA ,-Sp. 
Plate 8, fig. 11. 
I think my friend and master, Sowerby, has put a muscle 
too many in this shell. I cannot find the traces of two in the 
valve figured (c), but the general form is faithfully given. The 
deep valve has but a very small beak and attachment, nor is 
the anterior side much angulated or steep. The shallow valve 
is gently curved. The shell is smooth, but the characters of 
the surface are much obscured. 
None of the Ostreoid shells figured by Klipstein resemble 
this. But I hardly know how far the Ostrea aviculoides of 
his plate 15 may be allied to it. That is certainly a distinct 
species. But these Ostreidse are difficult to determine in the 
best of cases, and in this case the specimens are neither full 
grown, well preserved, or worth description. 
BRACHIOPODA. 
The shells of this group, from the Austrian Alps, have been 
fully described by Professor E. Suess. I availed myself, there¬ 
fore, of his visit to England, and he was kind enough to 
determine for me the following species, so far as they are 
identical with European species. I have no need to describe 
these afresh, but refer to the excellent figures of his mono¬ 
graph, as quoted below. 
ATHYRIS (SPIRIGERA) STROHMEYERI —Suess. 
Plate 9, fig. 10. 
Denkschrift., Akad. Ivais. Kongl., vol. ix., t. 1, figs, 4, 5, 6. 
Our specimens are a little broader than the Alpine forms, and 
show nothing of the central furrow. But only one of Professor 
Suess 5 does so.
