BRITISH DEVONIAN BRACHIOPODA. 31 



were connected. After many inquiries in different directions Prof. Zittel informed me 

 that he beheved there existed in the Imperial Museum of Vienna some specimens that might 

 help in this investigation, and accordingly my old and valued friend Prof. E. Suess at 

 once kindly obtained for my inspection the important specimen shown in the woodcut 

 (fig. 1). In this are seen not only the attachments of the principal stems of the spirals 

 to the hinge-plate, but likewise their connection by the means of a curved bridge-like 

 process, which connects them at about half their length, small portions of the spirals 

 themselves being visible. 



We are indebted to Mr. A. Charapernowne, of Dartington Hall, Totnes, not only 

 for the discovery of the first British specimen of the genus, but also for finding a 

 specimen showing the cardinal process, which in TJncites gryphus is heart-shaped and 

 strongly developed. In Dev. Sup., PL III, I have given several figures of this interesting 

 specimen. The cardinal process is comparatively large, projecting, turned up, and bilobed 

 at its extremity, and crooks under the concave deltidial fissure of the ventral valve. Its 

 posterior portion encroaches on the extremity of the umbo of the dorsal valve, and on 

 either side, in the interior of the valve, are two raised channelled prolongations, to which 

 the principal stems of the spirals, in all probabiUty, were attached. On each side of 

 these are the open pouch-shaped expansions. This valuable specimen was found by Mr. 

 Charapernowne in the Devonian Limestone of Orchard Quarry, Dartington, Devonshire ; 

 and was presented by him to the Albert Memorial Museum, Exeter. I am indebted to 

 the curator, Mr. d'Urban, for the kind loan of the specimen. 



Vncites (jryphus is not a common fossil in Devonshire. Most of the specimens at 

 present known were obtained by Mr. Champernowne near Dartington. Mr. Vicary has 

 obtained well-characterised specimens, from the Chudleigh Limestone in Devonshire, which 

 I have seen. Mr. Champernowne has procured the fossil out of Triassic conglomerate 

 at Shaldon, opposite Teignmouth. It occurs in a black marble, from which sections 

 can be cut. Mr. Pengelly also kindly lent me out of the Torquay Natural History 

 Museum a similar boulder of black marble, which had been found at Petit-tor Beach 

 just east of Babbacombe, and about three miles east of Torquay. This, having been 

 cut and polished, exhibited a number of fine sections of TJncites gryplius, of which we 

 have given a figure. 



We still remain unacquainted with the shape and position of the muscular impres- 

 sions, but these will in all probability be some day discovered. 



Uncites yryphus varies considerably. Some specimens show the lateral open pouches, 

 others none. I have seen from PafFrath specimens of Uncites measuring three inches in 

 length and upwards. A specimen from Shaldon measured two inches and five eighths in 

 length : and some young specimens had pouches, others none.
