P. 75-77. Three small fishes in side view, showing the principal 
characters of the genus and species. In the second 
specimen the space originally occupied b}’ the notochord 
is filled with calcite, which proves that a delicate thread 
persisted piercing each centrum. This and the third 
specimen also exhibit the peculiar form of the pelvic 
bones, one of which is restored in the diagram, text- 
fig. 7. The main portion of this element gradually 
expands towards its anteriorly directed end; it is con¬ 
tracted presumably at the point of origin of the pelvic fin, 
and thence sends a small expanding process inwards to 
meet its fellow of the opposite side. Lewis Coll.

Type. Imperfect fish ; Museum of Laibach, Austria. 
The type species of the so-called Saurorhamphus, attaining a 
length of about 0'2. Head with opercular apparatus occupying 
one third of the total length to the base of the eaudal fin. 
Ornament apparently as in E. hoissieri. Fins almost as in the 
latter, but abdominal region probably somewhat more elongated. 
Four large dorsal plates behind the occiput, ovate in form, very 
slightly overlapping, ornamented with fine tubercles, and not quite 
reaching the dorsal-fin; lateral scutes smaller, irregularly tri¬ 
angular, and notched (perhaps also perforated) by the sensory canal. 
The erroneous restoration by Heckel gives a very false idea of 
this fish. Every feature in its osteology hitherto definitely dis¬ 
covered, suggests that its reference to the genus Eurypholis is 
correct. 
Form. Log. Cretaceous : Comen, Istria. 
Not represented in the Collection. In addition to the type, the 
only known specimen is an imperfect fish in the Museum of the 
Imperial Geological Survey, Vienna,- described by Kner, loc. dt.
