eounty of Limerick, which, from its containing several new forms, and the fine state 
of preservation of many of the specimens, presented points of structure and other pecu- 
liarities not before described. The fauna of the carboniferous limestone period, 
which is usually one of the richest in zoophytes, in this collection is represented only 
by a small proportion, principally belonging to the division Zoantharia tabulata of 
Prof. Milne-Edwards, amongst which are the genera Michelinea and Chetites, with 
the characteristic and extensively distributed coral Amplexus coralloides. The Echino- 
dermata, which are most familiar to us in a fossil state, in this collection belong 
almost entirely to one division of crinoids, the Melocrinide, consisting of numerous 
detached bodies, principally of Platycrinus and Actinocrinus, genera almost exclusively 
confined to this formation. Remains of animals of the class Bryozoa or Polyzoa, now 
included with the Mollusca, are well exhibited by various forms, principally belonging 
to the family Reteporidz, amongst which are fine specimens of the well-known form 
Fenestella membranacea of Prof. Phillips. Of the Brachiopoda, the family Terebra- 
tulidee are represented by but one species, the Terebratula hastata, of which there is 
a numerous and fine series. Of the Spiriferidee, there are several characteristic species, 
together with the Athyris Roissyi, a singular and rare form belonging to this family, 
in which the lines of growth are developed into expansions, giving it a fringed appear- 
ance. Of the family Rhynchonellidz, are the common forms of Rhynchonella pugnus 
and pleurodon. The Orthidz are represented by the well-known Orthis resupinata, and 
the very rare species Orthis radialis, and other well-known forms. Also numerous 
examples of several characteristic and some rare species of the family Productidz are 
found, including Productus aculeatus; and a new species. Of the genus Chonetes there 
are several interesting and rare varieties, including C. variolata (D’Orb.) and C papi- 
lionacea. The Conchifera, or Lamellibranchiata, form a fine series, containing several 
new forms, amongst them being several species of the genera Aviculopecten and 
Pteronites (M‘Coy), shells having an oblique axis like most of the so-called Pectens of 
the coal-measures. Of the singular shell called Conocardium Hibernicum (Pleurorhyn- 
chus of Prof. Phillips) several instructive specimens were collected, showing the ex- 
panded keel and siphonal tube, which in some species is still more extended, being pro- 
bably analogous (as suggested by Mr. S. P. Woodward in his ‘Manual of the Mollusca’) 
to the soft, elongated siphons of a remarkable group of cockles inhabiting the inland 
salt seas, Aral and Caspian, burrowing in mud; also a second species, of which several 
specimens were collected, some of them attaining a larger size than the C. Hibernicum, 
being remarkably perfect, and having a long siphonal tube, which Prof. De Koninck 
agreed with the author in considering an undescribed form. He proposed, therefore, to 
dedicate this magnificent species to that distinguished palzontologist under the name 
of Conocardium Koninckit. There are several species of the genus Cardiomorpha, one 
of which, C. Koninckii, is new to Britain, and another, a new species, of large dimen- 
_ sions. ‘The Gasteropoda, or univalve shells, are also numerously represented by many 
genera and species, including a new species of Macrocheilus, and other undescribed 
forms. Of the Nucleobranchiata, believed to be allied to the floating shells of the 
present day, this collection contains several species of Bellerophon and Porcellia Puzo, 
a discoidal form of great rarity, The highest order of Mollusca, and most important 
geologically, are those of the Cephalopoda, which are here remarkable for size and 
rarity of form, all belonging to the order Tetrabranchiata. The Nautilide contained 
many large and fine specimens, some of them being new species. Of the Orthocera- 
tidze, specimens were collected of Orthoceras Muensterianum, fine examples of O. dacty- 
liophorum, and the peculiar formsof Gomphoceras (Poterioceras) fusiforme and Cyrto- 
ceras Verneuilanum; also of the Goniatites, a division of the Ammonitide, several 
species, including G. crenistria and fasciculatus, alluded to as contained in this col- 
lection, some of them showing external markings and others being new forms, 
On a New Fossil Fern from the Coal-Measures near Glin, County 
Limerick. By W.H. Batty, F.G.S. ' 
The fossil plant alluded to by the author, and of which an enlarged representation 
was given, was collected by Mr. G, Henry Kinahan, of the Geological Survey, from 
the black shale above the coal townland of Ballygiltenan Lower, county of Limerick, 
associated with ordinary coal plants. It appeared to be the central portion of a frond,
