at their upper margins. There are 12 of these flattened shelving ribs on 

 the pleura and 12-15 on the axis. Each of the pleural ribs shows trace of 

 a fine surface groove. The test is very thin and its surface so far as known 

 very finely granulate. The specimen has a length of 35 mm and a width of 

 44 mm. I should be at a loss for a known species with which to compare 

 this tail. In respect to the character of its segments and its thin test it is 

 like D. limulurus, the well known Upper Siluric species of New York, 

 but therein the resemblance ceases. 



Species name. Nicholas Cox, governor of Gaspe after the English 

 conquest.

This species is one of the rarest in the fauna of the New Scotland 

 beds (Helderbergian) in eastern New York and has not been elsewhere 

 found save at the locality here considered. The description was based on 

 a series of pygidia only but the writer has collected the other parts so that 

 the species is pretty well understood. All New York specimens of the 

 pygidia are of uniformly small size, bear an entire and spineless margin, a 

 broad flat median rib with seven narrow and subequal ribs on each side. We 

 have a single pygidium agreeing with these New York specimens in all 

 details even to size, obtained by me in the St Alban beds in Cape Rosier 

 Cove. 



The name used by Logan as above cited doubtless had reference to this 

 species. We elsewhere note the presence of a large varietal expression of 

 B. barrandii in the fauna of Stewart's Cove, Dalhousie .
