1. "Descriptions of New Corals from the Carboniferous Lime- 

 stone of Scotland." By James Thomson, Esq., E.G.S. 



In this paper the author described some forms of corals from the 

 Carboniferous Limestone of Scotland, which he regards as new 

 species, and as belonging to three new genera allied to ClisiopJiyllum. 

 In the group which he names Rhodophyllum the calice is circular and 

 shallow ; the epitheca thin and smooth ; the septa thin and numer- 

 ous ; and the columellar boss dome-shapec!, slightly raised above the 

 inner margin of the primary septa, and elapsed by subconvolute 

 ridges. The species referred to this genus are Rhodophyllum Craig- 

 ianum, R. Slimonianum, R. Phillipsianum, R. Argylianum, R. reticu- 

 latum, and R. ellipticum. Aspidiophyllum has the calice generally 

 circular, shallow ; the septa forming thin lamina? for about half their 

 length from within, when they become flexuous, and the columellar 

 boss promient and helmet-shaped. The species are named A. 

 Koninckianum, A. Suxleyanum, A. cruciforme, A. elegans, A. Hennedii, 

 A. Danai, A. dendrophyllum, A. ellipticum, A. Pagei, A. scoticum, and 

 A. laxum. The third genus, Kurnatiophyllum, is most nearly allied 

 to Rhodophyllum, but has the columellar space slightly raised above 

 the inner margin of the primary septa, and crowned by bending or 

 wavy lamellae, some of which pass over the central space in sinuous 

 folds. The species are described under the names of R. concentricum, 

 clavatum, Tyler anum, intermedium,, ellipticum, Ramsay anum, Youngianum, 

 Harlcnessianum, lamellifolium, bipartitum, octolamellosum, Maimianum, 

 Edwardsianum, and Davidsonianum. In a specimen of Aspidiophyllum 

 Suxleyanum the author noticed in the open interseptal space a small 

 tube, 4 lines long, around the inner margin of which there was a 

 group of oval bodies, which, from their close proximity to the inner 

 margin of the primary septa and their form, he is inclined to think 

 may be ova.
