2. Petraia sp? This coral is small, having a diameter 10 
m.m. It seems to be a cast of the top of the calyx. The septa 
are numerous, being distinct around a fourth of the cireumfer- 
ence, Where the number is twelve, making a total of 48. A 
carapace valve of a Beyrichia covers the half of it. 
5. Beyrichia 2 sps. These are numerous. We have Cara- 
pace valves of at least four distinct forms, representing, possibly, 
two species. At Nictaux two indistinct valves were found which 
were supposed to resemble Beyrichia kloedeni. 
Here they are decidedly different and undetermined. 
6. <Asaphus ditmarsie.—tThis trilobite, which I described and 
named in the last year’s Transactions, is one of those giant 
forms which appear and culminate in the Lower Silurian, and 
survive to the middle or intermediate Silurian period. Its bed- 
ding here is magnetyte. 
7. Dalmanites gilpini is also from the mines, of this I have 
only a glabella. This however is in good preservation. It is 
broken off at the occipital furrow. From this to the front, the 
length is 19 m. m. . This is equal to the width of the frontal lobe. 
The width of the anterior lobes is 16 m. m., of the median 14 m,
