128. Ateleocystites Fletcheri. 
In the Geological Magazine, 1871, Vol. VIII, p. 71, Mr Woodward calls attention to the genus 
Ateleocystites of Billings figured and described by him in Decade tt. of the publications of the Geological 
Survey of Canada, Montreal 1858. In a letter which accompanies this notice, Mr Billings considers <A teleo- 
cystites, as suggested by Mr Woodward, to be generically identical with Placocystites, of De Koninck, Geol. 
Mag., 1870", Vol. VIL, p. 260. Pl. vit, figs. 2, 3, 4, and with Anomalocystites, of Hall, Pal.. New York, 
1859, Vol. Ill, p. 132, pl 7a. and 88. 
The Ateleocystites Fletcheri appears to be the same species as the A. (Placocystites) Forbesianus of 
De Koninck; both were obtained from the Wenlock limestone of Dudley. Figures of more perfect specimens
