continued across." (Hicks.) A. impar, Hicks, has the flexuous 

 eye lobes of our species, but the marginal rim is more decidedly 

 in contact with the front of the glabella, while the two median 

 pairs of furrows extend further inwards.

Paradoxides tenellus, spec. nov. 

 Fig. 12. 

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

 anterior third of the length, 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 of the 

 glabella, while the small one in front is somewhat shorter. The 

 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 extremity 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 the last glabella furrow. The dorsal furrow 

 is distinctly impressed along the posterior half of the glabella 

 but obscurely marked in front. 



The surface is minutely granular. In all of the three speci- 

 mens collected there is a small straight rounded ridge, which 

 runs from the front of the glabella to the mar2:in. 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, including neck 

 segment and front margin. 



Occurs at Chapel Arm, Trinity Bay. 



Paradoxides decorus, spec. nov. 

 Description. — The form of the glabella of this species is nearly 

 the same as that of P. tenellus but the glabellar furrows are
