WELLBURN : FISH FAUNA OF THE LOWER COAL MEASURES. 427 
Detached scales ornamented with "strongly marked diagonal 
ridges which run nearly straight and parallel across the scale." 
Found in both districts, but rare. PL LXII., fig. 5. 
Sp. 2. E. semistriatus Traquair. 
Detached scales with the following ornamentation : — Anterior 
surface of scale is covered with well-marked "furrows and ridges 
which run backwards and downwards, some bifurcating or joining 
others and sometimes multiplied by intercalations. The posterior 
portion is occupied by numerous coarse punctures." PI. LXII., 
fig. 4. 
A fine Maxilla from the Lower Foot Mine I refer to this 
species. It is ornamented with '* fine wavy, branching and 
anastomosing longitudinal ridges, the dentary margin being finely 
tuberculated." No teeth shown. This species is found in both 
districts, but is very rare. 
Sp. 3. A\ Egerto7ii (?) Agassiz. 
Some detached scales show the ornamentation of this species, 
viz. : — " Well-defined ridges and furrows, the ridges being oblique, 
irregular, branching, intercalating, and ending at the posterior 
margin in acute serrations." On some scales one or two of the 
ridges run close to and parallel with the anterior and inferior 
margins. Very rare. 
Sp. 4. E. Binneyi Traquair. 
A small fish found in a nodule from the 40 yards' mine, 
Littleborough. The whole body to the commencement of the 
caudal fin, about two-thirds of the head much crushed, and also 
parts of Pectoral, Ventral, Anal, and Dorsal fins are shown. 
The length of the specimen is 8 cm., and the greatest depth of 
the body, at a point a short distance behind the head, is 30 mm. 
Head is much crushed, and I am unable to identify any of 
the bones with the exception of one or two of the "branchio- 
stegal rays." 
Shoulder girdle, Supraclavicle, Clavicle and infraclavicle 
shown, the last two being crushed back and disarticulated from 
the former. The bones seem to be ornamented with well "spaced 
ridges which are more or less concentric with the margins."
