Serpula epithonia (Goldfuss), Petref. vol. i. p. 225. t. QJ- f. 1. 



Shell tapering, slender, attached by the whole length of its inferior 

 surface ; upper surface convex, transversely wrinkled. Length 6, 

 width 1 line. 



Obs. — This fossil is found at Kwang-si, attached to Spirifers ; it 

 likewise occurs at Bensberg, Ferques, &c.

A slightly produced creeping Polypidom, adhering to shells or to 

 other marine objects, and composed of a succession of trumpet-shaped, 

 tapering, divaricated tubes, fixed by all their length, more elevated 

 at their broadest extremity, which is perforated by a circular or 

 ovular aperture ; the gemmation takes place near the calyx, either on 

 the same line as the parent cell, or laterally ; the average length of 

 each polypidom slightly exceeds 2 lines, and the greatest width near 

 the calyx does not much surpass 1 line. 



Ohs. — I have referred the Kwang-si Polypidom to the Aulopora 

 tubceformis of Goldfuss, a species very common in most Devonian 

 localities, where it is found incrusting shells and corals. It is espe- 

 cially abundant in the Eifel, at Reifrath, Ferques, Nehou, &c. 



In order to complete and conclude this short account of the De- 

 vonian fossils from China at present known, I have added a brief 

 description of the two Yuennam species, which will be found more 

 amply described and illustrated in M. de Koninck's paper on the 

 subject, and from which figures 17 and 18 are taken. 



9. Spirifer Cheehiel, De Koninck, Pl. XV. fig. 17. 



Spirifer Cheehiel, De Koninck, Bulletin de I'Academie Royale des 

 Sciences, Lettres et Beaux Arts de Belgique, 1846. 



Shell transverse, subtriangular ; hinge-line longer than the average 

 width of the shell ; beak small, moderately incurved ; area narrow, 

 slightly concave ; the convexity of the shell is interrupted by a wide 

 sinus in the dental or ventral valve, which corresponds to a mesial 

 fold in the dorsal valve. Sixteen or seventeen rounded plaits ornament 

 the surface of each valve ; the sinus and mesial fold are without 

 costse. Length 16, width 33, depth 11 lines. 



Found by M. Itier in a grey limestone in the province of Yuen-
