Notes on Fauna. 



2. Petraia sp ? This coral is small, having a diameter 10 

 in. m. It seems to be a cast of the top of the calyx. The septa 

 are numerous, being distinct around a fourth of the circumfer- 

 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 j 

 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 ? ditmarsice. — This 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 magnetite. 



7. Dalmanites gilpini is also from the mines, of this I have 

 only a globella. 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
