748 ME. F. -R. C. EEED ON THE LOWEE PALEOZOIC [NoV. 1899^ 



Occurrence. — From the character of the rock the specimens 

 seem to have come from the lower part of Stage 3, Tramore Lime- 

 stone Series. 



Remopleueides tubeeculatus, sp. nov. (PI. XLIX, fig. 5.) 



Glabella subcircular to transversely oval, moderately convex, vrith 

 large abruptly projecting frontal tongue, with parallel sides and 

 rounded anterior end, measuring in length two-fifths that of the 

 glabella, and in breadth rather more than one-third its greatest 

 width. 



Surface of glabella marked by one distinct pair of basal furrows 

 obliquely curving backward, but not reaching the neck-furrow or 

 axial furrows. An indistinct second pair is observable in some 

 specimens. The whole surface is also ornamented with coarse 

 tubercles of equal size. 



Eyes narrow, linear, encircling the sides of the glabella, and in- 

 denting its base, where they rather suddenly increase in width as 

 they bend round to the neck- furrow. 



l^eck-furrow deep. Neck-ring rather narrow antero -posteriorly, 

 measuring only about one eighth the length of the glabella, and 

 ornamented with similar tubercles not arranged in rows.

The tuberculated glabella of this species recalls Salter's descrip- 

 tion of U. ijlatyceps, but in no other respect do the species resemble 

 one another. The single pair of furrows and the tuberculated 

 surface of the glabella mark it off from R. Portlocki and R. Salteri. 



B. Barrandii, Nich. & Eth. has three pairs of furrows and other 

 points of difference. B. Panderi, Billings ^ agrees in having a single 

 pair of furrows, and B. canadensis, Billings ^ in possessing a 

 tubercular ornamentation. 



Occurrence. — B. tuherculatus is found at the top of Stage 2 

 and in Stage 3 of the Tramore Limestone Series in JS'ewtown Cove. 



Cheieuetts gelasikosus, Portlock. 



Occurs in Stages 2 & 3 of the Tramore Limestone Series. The 

 larger specimens show the typical characters as described in detail 

 and figured by Salter,^ Some of the smaller specimens, which I 

 attribute with some hesitation to this species, may possibly owe their 

 points of difference to age, but they show a remarkable resemblance
