Palceaeis cuneata, Meek & Wortlien; 

 Carboniferous Limestone, n«ar Henbury, BristoL 



Mr. Eobert Ethoridge, jun., F.G.S., has kindly favoured me with 

 the following remarks on some specimens forwarded to him. 



"Your fossil appears to be the Palceacis cuneata described by 

 Meek & Worthen in the Proceedings of the Academy of Natural 

 Sciences of Philadelphia (1860, p. 448), and is there referred and in 

 their Geological Eeport (vol. ii. p. 262, pi. 19, fig. 1 a-d) to the 

 Petrospo7igidce, under the name of Sphenopoterium. Meek & Worthen 

 at first regarded it as a coral, believing the strise seen within the cells 

 to be septa, but placed the genus amongst the sponges on the 

 authority of Prof. A. E. Yerrill, of Yale College, who considered 

 that sueh might perhaps be the affinity of the American fossil. 



"Prof, de Koninck refers^ the various species of Sphenopoterivm 

 to the genus Palceacis of Jules Haime, which appears to have a slight 

 precedence over Meek & Worthen's name. 



" Prof, de Koninck states that M. von Seebach first pointed out the 

 identity of Splienopoterium and Paleeacis,^ and that it was a true 

 perforate coral of the section Madreporidse of Edwards & Haime. 



" The American specimens are from the St. Louis Group of the 

 Lower Carboniferous series ; locality, Spurgen Hill, Indiana. The 

 specimen agrees generally with the specific characters assigned to 

 P. cuneata, viz. compressed, cuneate, longer than wide; calices from 

 two to five, deep, with an oval aperture and directed obliquely out- 

 wards and upwards, with crenulate vermicular strise, covering the 

 whole of the external surface. 



'•Prof, de Koninck appears to consider P. [Splienopoterium) 

 cuneata, M. & W., as identical with P. cuneiformis, J. Haime, which 

 is perhaps the more correct name for the fossil, although I am not 

 acquainted with the description of the latter. 



"I have not before heard of the discovery of Palceacis in this 

 country." 



YIL— Note on the Ocgurrence of Phosphatised Caebonate of 



Lime at Cave Ha, Yorkshire. 



By J. E, Marr, St. John's College, Cambridge. 



IT may be worth while to record the occurrence of phosphatised 

 carbonate of lime in Cave Ha, near Giggleswick, which has 

 been explored by Prof. Hughes (see Journal of the Anthropological 



^ In his Nouvelles Recherches sur les Animaux Fossiles du Tarain Carbonifere de 

 la Belgique, p. 154.
