maximum height at the centre (Pl. Ill, fig. 11). All our specimens of A. diibiosa 

 are somewhat compressed, showing an irregular carina on the posterior slope (fig. 

 10 a). Surface only ornamented with lines of growth. 



Length 4 mm., width 3 mm., height 1,6 mm.

Bellerophon buccinatus n. sp. 



Fl. III. fig. 12 and textfig. 



Shell involute, inflated. Aperture expanded. Upper lip slightly lohed. Slit band 

 rounded, moderately elevated, from l h to 3 A mm. in breadth. The ornamentation 

 of the surface consists of fine transverse lines (see textfig., pag. 36); also slight 

 traces of longitudinal stria? are distinguishable. 



Breadth of aperture 10 mm. 



Locality a. 



Hyolithus fabaceus n. sp. 



PI. III, iig. 14 and 15. 



The conical shell rapidly tapering, longitudinally somewhat curved toward the 

 ventral side. The dorsal side, transversely flat or slightly concave, meets the convex 

 ventral side in a rounded margin, in consequence of which the transverse section, 

 being about twice as wide as high, gets a reniform outline. The form of the 

 opening cannot be stated. The ventral surface is marked by fine longitudinal 

 stria?, the dorsal surface shows only slight concentric growth-lines.

Pl. IV, fig. 3—8. 



Head-shield parabolic, convex; genal angles produced into spines. Glabella wi- 

 dening anteriorly. Axial furrows deep and nearly straight. Frontal lohe, equalling in 

 length the remaining part of the glabella (the neck-lobe not included) is produced 

 in the front, with the both exterior sides rectilinear. The glabella has three pairs of 

 furrows, the first deepest and somewhat oblique, the second perpendicular to the axis 

 and inwards increasing in depth, the third nearly parallel with the second, but in 

 the inmost part a little more directed forwards, here being subparallel with the 

 neck-furrow. The neck-lobe rather convex, broadest at the middle. The glabella is 

 covered with fine granulée and scattered greater and smaller tuhercles. Also on the 

 cheeks such a granulation can be observed. The flattened lateral border, inwards 

 bouuded by a strong furrow, cannot be followed further than to the frontal lobe.
