E. W. Binney, V.P., F.R.S., stated that during the last 
session he had exhibited specimens of Zygopteris and Stau- 
ropteris found in the lower coal measures of Lancashire, short 
notices of which appeared in the Proceedings of the 9th Janu- 
ary and the 20th February, 1872. He now brought some 
drawings of other specimens of petioles from the same locali- 
ties, which appeared to belong to the genus Anachoropteris. 
One of them given to him by his friend Mr. Whitaker of 
Watersheddings, Oldham, was closely allied to Anachoropte- 
ris Decaisnii of Renault. It was of an oval form, measuring 
half an inch across its major and four tenths of an inch 
across its minor axis. 
Another singular fossil was from his own cabinet, and 
procured from the Lower Brooksbottom seam of coal. It 
was of a circular form and about one tenth of an inch in 
diameter. Its central axis was bounded by three crescent- 
shaped lines which joined together, and at their points of 
junction proceeded in three rays, which at their extremities 
diverged in numerous curved lines towards the circum- 
ference. These rays bore some resemblance to the five rays 
in an Anachoropteris figured by Renault in plate 10, 
fig. 2 of tome xii. of the Annales des Sciences Naturelles, 
but in the place of being embedded in cellular tissue as 
in the French specimen, they appeared to traverse a mass 
of reticulated tissue arranged in a series of curved lines so as 
to appear like three quadrants arranged within a circle 
with the central axis in the form of a spherical triangle in 
the midst of them. It is nearly impossible to describe the 
fossil without the aid of a figure. He considered that it 
would have to be placed in a new genus, and he had 
already found five or six different species.
