Description. — Glabella clavate, convex, most elevated at the 

 anterior third of the lenj^th, front and sides in the anterior half, 

 rounded, becoming sub-parallel in the posterior half Neck seg- 

 ment strongly elevated in the middle, where there is situated a 

 small tubercle, neck furrow extending all across. There are 

 four glabellar furrows, of which the posterior extends across but 

 is very indistinctly impressed in the middle ; the next two in 

 advance extend inwards about one-third of the width nf the ' 

 glabella, while the small one in front is somewb'<t shorter. The 1*^ 

 furrows are all nearly at a right angle to the longitudinal axis, '-< 

 and about equidistant from each other. The anterior margin of '''' 

 the head, is bordered by a narrow convex rim, which is separated 

 from the front of the glabella by a flat space, varying in width 

 from once to thrice its (the rim's) width. The fixed cheeks arc 

 subtriangular and nearly flat. The anterior extrenaty of the '-'■"> 

 eye lobe is situated at a point nearly opposite, but a little behind, '''' 

 the anterior furrows, and is close to, but not in contact with the '' 

 side of the glabella. The lobe is slightly sigmoid, its posterior '<'' 

 extremity opposite t\\v. last glabella I'urrow. The dorsal furrow 

 is distinctly impressed along the posterior half of the glabella 

 but obscurely marked in front. 



The surface is minutely granular. Tn all of tlie three speci- 

 mens collected there is a small straight rounded ridge, which '"^ 

 runs from the front of the glabella to the margin. It is situated 

 exactly on the median line. 



Of this species we have three specimens of the glabella, two of 

 which retain portion of the fixed cheeks and show the form of 

 the eye. The largest is three lines in length, iucluding neck 

 segmenv and front margin. 



Occurs at Chapel Arm, Trinity Bay.
