siderably below the glabella ; a deep furrow at the back corresponds to 

 the occipital furrow. 



A movable cheek supposed to be of this species, found in the same 

 assise, but at a different locality, has a correspondingly long eyelobe 

 curve, and is remarkable for the wide and high marginal fold ; this is as- 

 wide as the area of the cheek at the middle ; there appears to have been 

 no genal spine, but the lower outer corner of the cheek was bluntly 

 pointed. 



Detached pleurae occuring with the parts of this trilobite are like those 

 of Ellipsocephalus, bluntly rounded at the end, and have a straight furrow 

 deepening toward the end. 



Sculpture. The middle piece has a finely granulate surface; the 

 movable cheek appears to be more coarsely granulated, but this appear- 

 ance may be due to the coarseness of the matrix. 



Size. Length of the middle piece of the head-shield 12 mm., width at 

 the front 11 mm. ; at the back about 19 mm. Length of the movable 

 cheek 12 mm. ; width 5 mm. Length of a pleura 6 mm. ; width 2 mm. 



Horizon and locality. Assise E. 3/. Upper Etcheminian Fauna. The 

 heads from Gillis, Indian brook, the movable cheek and pleura from 

 Dugald brook, Escasonie, N.S. 



This species is referred to Solenopleura on account of the deep dorsal 

 furrows and occipital furrow, absence of occipital and genal spines, prom- 

 iment and rounded glabella, convex front area to the middle piece of the 

 head-shield, and strong eyelobe and fillet. 



It differs from all the species of Solenopleura of the Paradoxides Beds 

 by its long eyelobe. If it were not for this it would be near S. brachy- 

 metopa Ang. var. as figured by Dr. Brogger.* 



Taken alone the movable cheek referred to, this species compares best Resembles an 

 with that of an Anomocare, a genus of the Upper Paradoxides Beds of Anomocare. 

 Sweden. 



EURYPTEROID CRUSTACEAN ? PL XL fig. 3. 



A broken piece of the test of a crustacean was collected at Gillis Doubtful 

 Indian brook, which simulates the head-shield of a Xyphosuroid crusta- crustacean, 

 cean. If not this it is the axial ring of a trilobite, which bore paired 

 tubercles near the middle of the ring ; it is abraded at the front.
