Aptychopsis Wilsoni, T. R. J. and H. W., Monog. Foss. Phyll. Part II. 1892, 

 p. 105, pi. XV. figs. 12 (?), 15, and 16. 



Half of a carapace: Height (length), 14mm. Breadth, 8mm. 



This left-hand moiety of a carapace of good size lies apparently 

 over a displaced fragment of another part of the carapace, which 

 interferes with the angular shape of the nuchal notch.

Figs. 3, 4, 5, and 6 were lent by the authorities of the Carlisle

5. Eltmocaris Hindei, sp. nov. (PI. IX. Fig. 7.) 

 Length of valve, 24 mm. HeigM, 9 mm. 



We have here two valves of a carapace. The right valve is 

 nearly perfect, but has lost a piece off the hinder end, and is some- 

 w^hat cracked by pressure. The other valve lies obliquely and 

 partly embedded. 



The best-preserved valve is elongate, pod-shaped, straight above, 

 with a nearly semicircular outline below; antero-dorsal angle sharjj ; 

 posterior end of the valve tapering, but fractured, — certainly not

broadly truncate originally. A distinctly elevated ocular spot is 

 visible at about one-seventh of the length of the valve, a little 

 below the margin, in the antero-dorsal region. Delicate longi- 

 tudinal striae, parallel with the margin, interrupted, and slightly 

 anastomosing, ornament the ventral part of the surface. This 

 pattern passes upwards into scattered minute shallow pits ; and 

 above the middle of the valve there is a linear arrangement of 

 fine short striae, with shallow pits interspersed (see Fig. 2).
