Silurian Fossils of Nova Scotia, 159 



Two specimens only of this species have been observed, both of 

 them having the same dimensions. 



36. Tentaculites distans. var. 



The specimens under examination do not present any important 

 points of difference from those of the Clinton group in New York, 

 In the Nova Scotia specimens there are numerous annulations 

 near the apex, which are not observable in the New York speci- 

 mens. 



37. Helopora feagilis, var. acadiensis. 



The specimens under examination offer no very important dif- 

 ference from those in New York, and as the Nova Scotia examples 

 have been more or less compressed and worn, they are scarcely in 

 a satisfactory condition for nice discrimination. 



All the above fossils belong to the Arisaig series of Mr. Daw- 

 son's paper. Nos. 4, 10, 30, 36 and 37 appear characteristic of 

 the dark and olive shales of the lower member, in which are also 

 StropTiomena profunda^ S. ruffosa, Orthis testudinaria, Atrypa 

 emacerata, Khynconella equiradiata, Graptolithus Clintonensis, 

 and crinoidal columns ; also a Modiolipsis allied to 31. subcari. 

 natus. The remaining species are in the coarse limestone and 

 reddish shale of the upper member, in which are also StropTio- 

 mena corrugata, Atrypa reticularis , Rhynconella neglecta^ Lin- 

 gula ohlongaj Bucania trilohita, and a Chmtetes or Steiwpora 

 similar to that of the Clinton formation. Cornulites flexuosus is 

 almost the only species which occurs equally in both groups of 

 beds. Some of the CUdophori are also found in both groups.
