fifteen feet bed of trap and the chalk below there occurs at Kil- 

 corig a carbonaceous band of from three to twelve inches thick. 

 This band is composed of lignite, or semi-coal — like charred 

 wood j indeed, the woody nature is quite evident, and several 

 good specimens of the deposit were secured. This band was origi- 

 nated probably by the overturning of some forest, as the melted 

 trap flowed from its source. A more extensive bed of the same 

 kind occurs at Killymorris, a few miles from Ballymena, where 

 it is extracted as from a regular coal mine and sold for fuel. 

 The Kilcorig quarries furnish a very excellent assortment of 

 fossils, more remarkable for the great variety of species than 

 for the number of individuals, and the collectors of the party 

 obtained several species new to their cabinets ; indeed, the 

 gathering on this excursion was the richest made for the year, 

 and included good specimens of the following species : — Am- 

 monites Gollevillensis, Nautilus radiatus, N". lsevigatus, Helico- 

 ceras Hibernicum, Belemnitella mucronata Turritella unicari- 

 nata, Trochus cirrus, Pleurotomaria perspectiva, Lima elegans, 

 Pecten nitidus, Pholadomya cordata, P. obliquissima, P. 

 Stewarti, Ostrea vesicularis, Area, albse-cretse, Terrebratula 

 abrupta, T. semiglobosa, T. carnea, Rhynchonella octoplicata, 

 It. plicatilis, Ananchytes ovatus, Micraster cor-anguinum, and 

 Galerites abbreviatus. The weather-worn surfaces of several of 

 the chalk rocks are covered with the beautifully ornamented 

 spines of fossil sea-urchins, and with fragments of corals that once 

 lived together in deep seas, at the bottom of which the limestone 

 itself was deposited as mud, and the closer the rock is examined, 

 the more it is found to be made up, as it were, of deep sea forms 

 of animal remains. Sponge remains are also common at Kil- 

 corig ; and one species, Guettwdia stellata, assumes the shape 

 of a distinct cross, of the form which ecclesiologists would call 

 the " Calvary cross," in contra-distinction to the Greek, 

 Latin, and crosslet types. Amorphospongia ramosa ramifies 

 over some of the beds, and specimens of the Paramudra 

 Buchlandi occur in great abundance — indeed, more frequently 

 than is profitable to the quarry owner, for, being composed of 

 flint, they are useless for lime. After thoroughly exploring 

 the quarries, Mr. Megarry very kindly took the party to his
