RHYNCHONELLIDiE.

logist was not acquainted with our British species, nor does it appear to be a common 

 fossil, except in a few localities in England and abroad. 



The original specimen of Sowerby's " Terehratula crispata" is in the Museum of the 

 Geological Society. It is a moderately convex example of T. StricMandii, and was so 

 identified by Mr. Salter some years ago while rearranging Sir R. Murchison's Silurian 

 collection, presented to that Society. 



Position and Locality. B. StricMandii appears to be rare in the Woolhope beds ; 

 common in the Wenlock limestone and shale ; and rare again in the Aymestry limestone. 

 It occurs at Nash Scar, Presteign, in Woolhope beds. In Wenlock shale at Gaer-coed, 

 Tucking Mill, Craig-y-coed, and Bryn Craig, in the Usk district ; in Wenlock limestone 

 at Hobbs, Longhope, and the Rock, May Hill district; Croft, and east of Ledbury, 

 Malvern district ; Rushall Canal, near Walsall ; Dudley ; Sedgley ; Canwood, and 

 Dormington, near Woolhope. At Llanbadoc, in Aymestry limestone, Usk district 

 (Phillips and Salter). I am not acquainted with any Scottish or Irish example. 

 Abroad it was met with by Dr. Lindstrom in the Island of Gothland, but there it 

 appears to be exceedingly rare.
