296 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Pcb. 21, 



cene deposits of Jamaica, as stated in a letter of that naturalist quoted 

 by Dr. Woodward, an extract from which will be found in a note to 

 my paper on the Jamaica fossils (p. 281). It is even possible that 

 one of Mr. Barrett's fossils may be identical with one of the species 

 now described. At any rate these fossils are interesting as being, 

 as I believe they are, the first Brachiopoda described from Miocene 

 beds in the West Indies. 



JN'one of the fossils now under consideration at all resemble 

 Maltese forms ; and herein they differ remarkably from many of the 

 other organic remains from the Caribean Miocene beds, especially 

 the Echinodermata and the Corals. 



All the species have been ascertained to be punctate. 



1. Terebratula trinitatensis, spec. nov. PI. XIX. figs, la, Ih. 



Shell smooth, gibbous, irregularly pentagonal, somewhat longer 

 than wide, marked by wide shallow and obscure sulci of growth, 

 which become finer and more distinct towards the margins ; front- 

 edge nearly straight ; ventral valve convex and rounded towards 

 the beak, flattened towards the front edge ; dorsal valve convex, 

 with an obscure carination radiating to each angle of the front edge ; 

 beak large, scarcely incurved over the dorsal valve, truncate by 

 a rather large subcircular foramen, from which a wide and shallow 

 sulcus extends forwards. 



2. Terebratula carneoibes spec. nov. PL XIX. fig. 2. 



Shell suboval or suborbicular, smooth, striated by fine lines of 

 growth ; ventral valve convex with a tendency to carination along 

 its mesial portion from the beak to the front margin ; dorsal valve 

 rather evenly convex, with an obscure slightly raised mesial fold ; 

 front margin rounded or somewhat produced ; beak small, scarcely 

 curved over the umbo of the dorsal valve, pierced by a very small 

 foramen. 



The front margin of the example figured is imperfect, but in 

 another less perfect specimen it is more folded and produced, giving 

 a suboval shape to the shell. The first-mentioned example resembles 

 in some respects T. carnea from the chalk. 



3. Terebratula lecta, spec. nov. PI. XIX. fig. 3. 



Shell suboval, smooth, sulcated by lines of growth which are 

 strong and well marked towards the margins, and which are crossed 

 by obsolete radiating grooves ; front edge plicate and sinuate ; ven- 

 tral valve somewhat compressed, especially towards the front margin ; 

 dorsal valve convex, with a slightly raised mesial fold; beak 

 scarcely incurved, truncated by a large circular foramen. 



Note on the Poregoing Paper. By T. Davidson, Esq., P.RS., F.G.S. 



The subject relating to Tertiary Brachiopoda is one of considerable 

 importance, since the fossils of this period, taken imder the ' homo- 

 taxeous' view, connect the Cretaceous with the Recent fauna. A
