neck-furrow well defined all across ; neck-segment thickened in the 

 middle and ^bearing a small tubercle. The fixed cheeks are strongly 

 convex, but not so prominent as the glabella. The dorsal furrows are 

 deeply defined all around the glabella. The front margin has a strong 

 rounded rim, separated from the front part of the cheeks by a narrow, 

 but distinct, groove ; between the groove and the front of the glabella, 

 there is a gentle depression, which separates the anterior angles of the 

 fixed cheeks. The eyes are small, situated a little in advance of the 

 mid-length of the head, distant from the side of the glabella a little less 

 than half the length of the head, and are connected with the front of the 

 glabella by an obscure ocular fillet. Surface with a few scattered 

 tubercles, just visible to the naked eye, and between these numerous 

 minute tubercles only seen when magnified. 



The glabella exhibits traces of two or three obscure furrows on each 

 side. Length of the largest head collected five lines. 



Occurs at Chapel Arm, Trinity Bay.

Description. — Glabella convex, most elevated in front, obscurely 

 angular along the median line, widest at the anterior third of the length ; 

 sides gently concave in the posterior two-thirds, and slightly diverging 

 from each other forwards ; anterior third and front uniformly rounded. 

 Neck segment with the margin convex and projecting backwards, an 

 obscure tubercle, or rather, an angular elevation in the middle, neck 

 furrows all across. There are four glabellar furrows ; of these the 

 posterior is strongly marked and extends in a nearly straight lino all 

 across ; the next two are linear, slightly impressed, extend inwards about 

 one-third the width of the glabella and arc gently curved backwards, but 

 still almost at right angles to the sides. The anterior furrow is short, 

 extends inwards about one-fifth the width of the glabella, and curves 

 backwards at an angle of about 45° to the sides. The dorsal furrow 

 around the glabella is very shallow. The fixed cheeks are triangular, 

 nearly flat, with a small elevation, close to the extremity of the posterior ,
