﻿COCCOSTEIDJE. 285 



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 Bamna 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 ventrolaterals are espe- 

 cially well displayed. Purchased, 1881 . 



P. 181. Small more imperfect individual, similarly crushed. 



Purchased, 1881. 



43966. 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, 1872. 



P. 5964-65. Two crushed specimens, the first showing possible 

 traces of a pelvic fin, the second with the pelvic basi- 

 pterygium. Purchased, 1889. 



20645* Nearly complete individual, imperfectly preserved • Strom- 

 ness. Purchased, 1846. 



P. 4310. Six portions of dermal armour, detached from matrix. 



Ennishillen Coll. 



P. 691. Imperfect detached mandibular ramus, partly in impression ; 

 Belyacreugh. This and the following specimen are 

 probably referred to by Newberry (Palaeoz. Fishes 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. 3217. Similar jaw. Ennishillen Coll. 



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

 the anterior denticulations. Ennishillen Coll. 



P. 692. Median ventral plate of small individual. Egerton Coll,
