LOXONEMA Sp. 



The single exception above-mentioned is an acutely turreted 

 shell 5 to 7 millimetres in height, and consisting of six whorls. In 

 general character it agrees with Loxonema ashtonense, obtained by 

 me from an adjacent colliery and described in this Journal. 1 The 

 surface of the shell is smooth, and lacks the longitudinal striaB seen 

 in L. ashtonense. I regard it as a species allied to the latter, but the 

 specimen is not sufficiently good to serve as the type of a new species. 



Horizon and locality. — Shales in the neighbourhood of the 

 Toad Vein, Lower Coal- Measures, South Liberty Colliery, Bristol. 



CEPHALOPODA. 



A small collection of goniatites was obtained, along with the 

 gasteropods, upon the spoil-heap of South Liberty Colliery. A small 

 series of minute coiled shells found in the shales may possibly 

 be the fry of goniatites, or of gasteropods, or of both. 



Gastrioceras listeri (Martin). 



A portion of the outer whorl of a large shell of this species was- 

 found. 



Horizon and locality. — Shales in the neighbourhood of the 

 Toad Vein, Lower Coal-Measures, South Liberty Colliery, Bristol. 



Glyphtoceras diadema ? (Beyrich). 



A very small pyritized fragment of the inner whorls of a goniatite 

 fortunately showed traces of the suture-lines, and I am indebted to 

 my friend Mr. G. C. Crick for his views of its relationship. 



Horizon and locality. — Shales in the neighbourhood of the 

 Toad Vein, Lower Coal-Measures, South Liberty Colliery, Bristol. 



Evidence of the occurrence of large goniatites has been obtained 

 in ironstone nodules, found upon the spoil-heap in Lower Coal- 

 Measures at Hanham Colliery. The material is very refractory, 

 and in no case could a specimen be got out, or uncovered in such a 

 way as to secure a clue to its genus and species.

Two small wing-fragments, 9 millimetres in length and 6 mm. in 

 breadth. One wing is partly superposed upon the other, the 

 lower one having its surface also in part concealed by matrix. The 

 uppermost wing is represented by a fragment of the distal hinder 

 portion, and by the wing-apex, which is bluntly rounded. The whole 

 aspect of the wing-fragment is pyriform ; but this is doubtless 

 misleading, as the outer margin is broken away, and no true 

 approximation to the original size or shape can be obtained. The
