significant remark that in the size of the corallites and shape of the 

 meshes the forms approach that described by Goldfuss as Oatenipora 

 labyrinthica. 



Occurs in the foetid limestone. 



Rugosa. 



The collection contains a few indeterminable specimens of a turbinate 

 coral suggesting Streptelasma, while equally indeterminable fragments of 

 a compound form may perhaps belong to Diphyphyllum. 



BRACHIOPODA. 



The following species occur together in a dark grey, compact limestone : — 



Stropheodonta varistriata (Conrad). 



The shells referred to this species agree with the form figured by Hall 

 and Clarke, Pal. New York, vol. viii., pi, 13, fig. 16. The internal characters 

 are not shown, but there cannot be much doubt as to the systematic 

 position of the species. 



Orthotetid. 



There are a few specimens of a flat shell of which only the external 

 features are seen. The most conspicuous character is the regular alternation 

 of fine and strong striae. 



Spirifer crispus (Hisinger). 



This is represented by a few small and indifferently preserved, but 

 unequivocal specimens. A faintly ribbed form accompanies the more 

 distinctly ribbed type. 



A trypa phoca (Salter). 



1852. Kliynclionella phoca, Salter, Sutherland's Voyage, pi. 5, tigs. 1-3. 



The collection contains a few specimens of this characteristic species. 

 They are accompanied by a less globose form, the true nature of which 

 cannot be ascertained. 



MOLLUSCA. 



Gasteropoda. 



The Gasteropods constitute the most striking element of the collection, 

 turreted forms being literally crowded on the surface of a large slab of 

 calcareous sandstone, and forming the main bulk of a large block of 

 dolomitic limestone. Tn spite of their abundance they are, with one 

 exception, indeterminable owing to their state of preservation.
