P. 687-8. Two specimens, one showing the impressions of several 
plates and nearly all the axial skeleton of the trunk and 
tail, the other considerably resembling No. P. 536 a, 
though with only half of the caudal region. The first 
specimen was obtained from E-amna Gio, the second from 
Belyacreugh. Egerton Coll. 
P. 180. A well-preserved skeleton showing portions of the double 
series of supporting bones and membrane of the dorsal 
fin, one of the pelvic elements, and a quadrate patch of 
tissue in the anal region. The median dorsal plate, the 
left dorso-laterals, laterals, and ventro-laterals are espe¬ 
cially well displayed. Purchased , 1881. 
P. 181. Small more imperfect individual, similarly crushed. 
Purchased , 1881. 
43986. Crushed individual, imperfectly preserved, displaying the 
supporting bones of the dorsal fin. The armoured portion 
measures about 0*17 in length, and the unarmoured caudal 
region 0*205. Purchased , 18/2. 
P. 5964-65. Two crushed specimens, the first showing possible 
traces of a pelvic fin, the second with the pelvic basi- 
ptervgium. Purchased , 1889. 
20645. Nearly complete individual, imperfectly preserved ; Strom- 
ness. Purchased , 1846. 
P. 4310. Six portions of dermal armour, detached from matrix. 
Enniskillen Coll. 
P. 691. Imperfect detached mandibular ramus, partly in impression ; 
Beh’acreugh. This and the following specimen are 
probably referred to by Newberry (Palaeoz. Pishes N. 
America, 1889, p. 132) as closely resembling the man¬ 
dibular rami of Dinichthys. The beak-like appearance, 
however, is due entirely to the accidental flaking of the 
bituminous substance into which the fossils are converted.

P. 4310 a. Detached mandibular ramus, showing teeth and two of
