[LAMBE] GANOID FISHES FROM NEAR BANFF, ALBERTA 39 
rays in the more anterior partof the fin have a breadthof about 1-5mm. 
at mid-length. Throughout, from near the lobe, they are closely 
articulated, five or six divisions occurring in a space of about 4 mm., 
plate I, figures 2 and 3. 
Many scales are indicated in the same plane of cleavage with 
the fin. They have a rough outer surface and are broadly oval in 
outline but somewhat pointed or narrowly rounded posteriorly. 
In none of them has the anterior margin been seen which leads to the 
belief that most of them are not much disturbed from their proper 
overlapping position, a belief strengthened by the fact that their 
posterior margins all point the same way or nearly so. 
The scale sculpture or ornamentation consists of many short, 
discontinuous enamelled ridges, having a general antero-posterior 
direction, but with an irregularly disposed appearance and showing 
a tendency to become squamous. These ridges may also be described 
as having the appearance of low-lying spine bases or very short 
spines pressed close to the scales surface, plate I, figure 4. The 
presence of many of the scales is indicated only by a slight convexity 
covered with this style of ornamentation. The scales vary in breadth 
from about 8 to 10 mm., and are longer than broad. 
Elonichthys cupidineus, sp. nov. Plate IT. 
The single specimen (Cat. Nos. 757, 757a.) on which this species 
is founded comes from the railway cutting at Massive and was also 
collected by Mr. Burling in 1915. It is in a sufficiently good state of 
preservation to show minute details of structure, and includes the lower 
hinder part of the head, and the trunk to near the base of the tail, 
with the pectoral, pelvic, anal and dorsal fins. The specimen has 
been freshly broken along a line running obliquely downward and for- 
ward from the anterior end of the dorsal fin to a point a short distance 
in advance of the base of the pectoral fin, and what was above this 
line, viz., most of the head and a large part of the back, is missing. 
Weathered fractures show that the lower front margin of the pectoral 
fin, and the tail with the distal part of the dorsal fin had probably 
been separated from the specimen, as it now is, for some time. 
The characters revealed indicate a species referable if not to 
Elonichthys to a probably allied genus which may prove to be unde- 
scribed. The trunk is rather deeply fusiform but no doubt the depth 
is increased to some extent by pressure. Fulcra are present in the 
fins, at least in the pectoral and plevic pairs. The rays of the pec- 
toral, pelvic and anal fins subdivide and are articulated. The base 
of the pectoral and pelvic fins is short, that of the anal and dorsal 
ones long. The anterior end of the base of the dorsal fin is apparently
