the total length of the fish. Dorsal fin arising at a point half as 
distant from the occiput as from the upper caudal lobe; caudal fin 
(according to Wagner) with convex hinder border.

Type. Nearly complete fish; Palaeontological Museum, Munich. 
A species attaining a length of about 0*09, similar in proportions 
to the type, but the caudal fin distinctly cleft; pelvic fins arising 
immediately behind a point opposite to the origin of the dorsal fin.

37931. Fine nearly complete specimen, in counterpart; Solen- 
hofen. The large, spaced conical teeth are shown in the 
premaxilla, maxilla, and dentary; and beneath the 
mandible there are remains both of the gular plate and 
branchiostegal rays. The neural and haemal arches are 
somewhat separated by crushing ; but the slender ribs in 
the abdominal region and the thickened haemal spines at 
the base of the tail are distinct. The characters of the 
median fin-rays are especially well-displayed ; and the 
few short rays at the origin of the dorsal fin are con- 
spicuous. The squamation is scarcely displaced in any 
part, but it is difficult to determine the precise form and 
proportions of the deeply overlapping scales.

P. 912. Specimen with more imperfectly preserved scales and 
caudal fin, and wanting the anterior half of the head; 
Solenhofen. The axial skeleton of the trunk, the pelvic 
fin-supports, and the impression of hard coprolitic matter 
in the intestinal tract, are noteworthy features.
