Fig. 284. Remopleurides ? Schlotheimi. a, b, two specimens of the glabella, both 

 distorted. 



Description. Glabella cylindro-conical, rounded and abruptly elevated 

 in front ; neck furrow extending all across ; three pairs of glabellar furrows 

 all inclining inwards and backwards, the middle pair only, continued across. 

 The eyes are semi-annular, about half the length of the glabella or a little 

 less, their anterior and posterior angles touching the sides of the glabella. 



The specimens are all more or less distorted, and hence the true pro- 

 portions of the parts cannot be determined. In all of them the space 

 between the side of the glabella and the eye (sometimes called the palpe- 

 bral lobe) is on a level with the median line of the glabella, thus forming 

 a nearly flat horizontal plane across from one eye to the other. A fine 

 thread-like groove runs round the lobe close to the eye. The surface 

 appears to be quite smooth. 



The pygidium found in association with the glabella above figured, 

 somewhat resembles that of Dikelocephalus magnificus. It is ovate with 

 an acutely conical axis, the side-lobes with five or six well defined ribs 

 each. The axis is about half the whole length, and the ribs of the side- 

 lobes incline backwards like those of a Remopleurides. The specimens 

 are too obscurely preserved to be figured. 



When compared with the head of Olenellus Thompsoni, the resemblance 

 was so perfect, that- 1 once thought this species was congeneric there- 

 with. Hence the reference in the Geology of Canada above cited. I now 

 think that both it and Dikelocephalus magnificus should be referred to 

 Remopleurides, or perhaps to some closely allied form. 



Locality and Formation. N, Table Head and Pistolet Bay ; P, four 

 miles N. E. from Portland Creek, Newfoundland ; Quebec group.
