the Eifel, wliicli Bronn, and afterwards independently Kayser, 

 separated from Fh. latifrons. The eyes are large and level with the 

 top of the glabella, which overhangs the strong marginal rim of the 

 front. There are eight lenses in the vertical rows of the eye. 

 Though it is a cast, indications remain that the glabella was as 

 roughly tuberculate as in Komer's figure, which Kayser refers to 

 this species. 



Calceola-schists and Eifelkalk. 



Obthoceras, sp. 



The cast, probably, but not certainly, of a body-chamber, shows 

 a central siphuncular opening. It is widely oval in section, but has 

 been somewhat squeezed. It might possibly belong to 0. ellipticum, 

 Miinster. 



Okthooeeas hercynicum, Kayser?

 p. 72, pi. X, figs. 7, 8, 11. 



Another cast appears to approach, or to belong to, this species. 

 Its section is oval, with diameters of 21 mm. and 18 mm., and the 

 siphuncle is situated on the longer diameter, nearly half-way from 

 the centre. The chambers are about four times as wide as high, 

 and are very obliquely placed.

 pi. xvi, fig. 6 ; pi. xs, figs. 11, 14, 15. 



A flattened cast may perhaps belong to Goldfuss's species, but 

 it does not retain suflScient character to admit of certainty. All that 

 can be said is that what remains of the fossil agrees with it, and 

 that the curvature of the apex and the rate of increase of the whorl 

 are the same. A few spots on the cast may perhaps indicate 

 the tubercles of that shell ; but they are far too indistinct to be 

 relied on, and may be entirely accidental marks. 



Upper Coblenzien and Eifelkalk.

? 1895. Conocarclium cuneatum, Beushausen : Abh. k.p. Geol. Laades., n.s., pt. xvii, 

 p. 407, pi. XXX, figs. 9-13. 



A large species of Conocardium is represented by a specimen 

 crushed almost beyond recognition. It measured about 18 mm. 

 across the valves, and its plaits were strong, squared, and close-set. 

 It appears not to have had any flattened central region. What 

 is seen of it suggests that it might be a small specimen of Komer's 

 shell, which, however, often reaches much larger dimensions.
