P. 1587. An imperfect much elongated fish, displaying the neural 
and haemal arches of the trunk and the pelvic fin-supports, 
partly used in the restoration, fig. 26, p. 131; Lower Lias, 
Lyme Regis. Egerton Coll. 
P. 3542-a. Two fragmentary heads, with some anterior scales, 
displaying the mandible, &c., from below; Lyme Regis. 
Enniskillen Coll. 
P. 3541. Pine cranium, described and figured by the present writer 
in Proc. Zool. Soc. 1893, p. 561, pi. 1. fig. 3 ; Lyme Regis. 
Enniskillen Coll. 
P. 1535. Laterally-compressed cranium showing vomerine teeth, 
with anterior neural arches of trunk exhibiting the separate, 
distally expanded neural spines ; Lyme Regis (?). The 
spines, so far as preserved, are directly apposed to, and 
do not overlap, the neural arches. Egerton Coll. 
P. 1537 a. Very small cranium, side view ; Lyme Regis. 
Egerton Coll. 
P. 1589 a. Imperfect right maxilla, premaxilla, and dentary ; Lyme 
Regis. Egerton Coll. 
P. 3551. More remains of jaws; Lyme Regis. Enniskillen Coll. 
P. 4877. Fine right mandibular ramus, inner aspect, showing both 
dentary and splenial entering the symphysis ; Lyme Regis. 
The splenial teeth are mammillated. Purchased , 1885. 
P. 1536, P. 1557 a. Two more imperfect left mandibular rami; 
Lyme Regis. As in the previous specimen, the splenial 
has the appearance of being forked behind and rising into 
the coronoid process. Egerton Coll. 
P. 4423. Imperfect small fish displaying the axial skeleton of the 
trunk; Lyme Regis. The neural spines are free as far as 
the middle of the caudal region, but then become fused 
with the corresponding arches. The ribs, though robust, 
do not extend to the ventral border of the trunk. The 
haemal spines in the caudal region meet their supporting 
arches at a considerable angle, are fused with them, and 
exhibit a small triangular expansion anteriorty below the 
point of union. Enniskillen Coll. 
P. 1556 a. Portion of trunk showing ribs, neural arches, and the 
inner aspect of the squamation ; Lyme Regis. 
Egerton Coll.
