Dukinfield. I am uncertain now whether (W, 757, e. coll. 

 Wild, M.M.) is from the former or the latter locality and 

 horizon, and I am too far away to refer to the specimens. 



From the Calif ornian or Thin Bed of FuUedge Colliery, 

 Burnley. (W. 954 and W. 1069, e. coll. Wild, M.M.) The 

 latter specimen is associated with Callopristodus pectinatus. 

 In black stone roof over seven inch inferior Coal, the latter 

 at 646 yards deep, Bardsley Colliery. (Greorge Wild, Trans. 

 Manch. Geol. Soc, Yol. XYIII., p. 426.) 



Hoplonchus elegans (Davis). 



This beautiful little fish spine, much like that of 

 Sphenacanthus hybodoides in miniature, has not hitherto, I 

 believe, been recorded from Lancashire, but I was able to 

 prove its occurrence in the Middle Coal Measures of Lanca- 

 shire by direct comparison with plaster casts of the types, 

 kindly sent to me whilst at Owens College, by Dr. A. Smith 

 Woodward. 



From the Arley Mine of Burnley. (W. 1104, e. coll. 

 Wild, M.M.) 



From Fulledge Colliery, Burnley. (L. 1699, e. coll. 

 Kay-Shuttleworth, M.M.) Horizon not stated but probably 

 the Arley Mine. The specimen is associated with a tooth of 

 Pleuroplax Rankinei. 



From over the E-oyley (Arley) Mine of Hurst, Ashton- 

 under-Lyne. (W. 1093, e. coll. Wild, M.M.) 



Lepracanthus Colei (Egerton). 



From the Arley Mine of Burnley. (W. 1103, e. coll. 

 Wild, M.M.) 



From Towneley Colliery, Burnley. Horizon not stated. 

 (W. 957, e. coll. Wild, M.M.) 



Cladodus, 

 This generic term has been frequently applied to teeth 

 of Sphenacanthus hybodoides, which see.
