be referable, but suggested the possibility of its being a depressed form or variety of 

 Rh. pugnus of Martin. After, however, comparing it with a large number of specimens 

 of the Carboniferous species, I could not match the Devonian specimens with any in my 

 collection. Viewed in profile the dorsal valve of B. pugnus presents a regular convex 

 curve, while in the three Devonian specimens 1 have been able to examine the dorsal valve 

 in profile presents, at a short distance from the umbo, an almost straight line. I have, 

 therefore, preferred to give the Lumraaton shell a distinct denomination, and have 

 named it after the distinguished geologist who did so much good work amongst our 

 English Devonian fossils. Specimens of Bhgnchonella agreeing in every particular wdth 

 the Carboniferous Rh. pugnus of Martin occur in the same quarry along with Rh. 

 Phillipsii, and can be easily distinguished. Mr. Whidborne informs me that he has since 

 seen several specimens in Mr. Champernowne's collection, which he had found in one day.

Since publishing my description of this species Mr. Chanipernowne has found a 

 larger and better specimen in the Middle-Devonian Limestone at Lummaton, near 

 Torquay. I did not previously know of its existence in tliat locality. Kayscr with 

 some uncertainty places it in the genus Camarop/ioria, and adds that Ter. suhtdragona 

 of Schnur and T. ascendens of Steininger are synonyms. Not being acquainted with its 

 interior arrangements, I can pronounce no opinion upon the subject.

Among a number of specimens collected by Mr. Whidborne from the Middle 

 Devonian Limestone of Lummaton I found a largish and well-characterised specimen of 

 this species. It measures six lines in length by six and a half in width. and three and a 

 half in depth. It seems to be a distinct and well-marked species.
