50 Messrs. Jones and Kirkby on Carboniferous Entomostraca. 



2. Tyrone ; Tinnaglogli. Soft grey shale. (Portlock's Col- 

 lection.) L. subrecta and L. Scotoburdigalensis. 



3. Fermanagh; Kesh. Dark-grey hard shale, full of Ento- 

 mostracous valves. (Portlock's Collection.) L. Scotoburdi- 

 galensis ; also Beyrichia and Bairdia ? 



4. Fermanagh ; Clebby. Soft grey shale, with Bivalve Shells. 

 (Portlock's Collection.) L. subrecta. 



5. Wexford (42/2) ; Whitestown House, Drinagh, near Wex- 

 ford. Dark- blue hard shale, with pyrites. (H. 4321.) L. sub- 

 recta and smaller obscure forms. 



III. " Carboniferous Slate." 



1. Cork (74/2) ; Glen near the city of Cork. Dark-grey 

 schist, weathering brownish : a hardened cleaved shale, with 

 small Brachiopods. L. subrecta (distorted). 



2. Cork (65/4); Bilberry Hill, N.E. of Middleton. Pur- 

 plish and rusty schist or hardened cleaved shale, with Cypri- 

 cardia, Encrinital joints, and distorted Entomostracous valves. 

 This schist lies between the " Old Red Sandstone " and real 

 *' Carboniferous Limestone^' continuous with that of Little 

 Island. This "Lower Limestone Shale" near Cork is 1000 ft. 

 thick, and all cleaved into slate ("Carboniferous Slate"). L. 

 subrecta and L. Scotoburdigalensis (distorted). These com- 

 pressed schists, with elongated and otherwise distorted Leper- 

 ditia, appear to be identical with some of the so-called " Cypri- 

 dinen-Schiefer" of Germany. Shales with Beyi'ichia arcuata (?) 

 distorted (from Granton and elsewhere) resemble other speci- 

 mens of " Cypridinen-Schiefer." Entomis supplies the other 

 so-called " Cypridinse " of these Rhenish strata. 



3. Cork (118/1); Relane Point, south side of Bantry Bay. 

 Grey schist, with pyrites, and weathering rusty. Gasteropods, 

 &c. This schist is probably 2000 or 3000 feet above the top 

 of the " Old Red " beds. Leperditia Scotoburdigalensis. 



4. Cork (67/2) ; Youghal. Drab schist, with an ochreous 

 parting which is full of well-preserved Entomostraca. This is 

 500 feet above the " Old Red " beds, and 300 feet below the 

 " Carboniferous Limestone." L. suborbiculata and L. parallela. 



5. Cork (105/1) ; Coory Commane Mountain, on the east side 

 of the Glen of Coomhola, Bantry Bay. Grey schist, micaceous: 

 a hardened squeezed shale, with small Bivalves. This specimen 

 was from the middle of the " Coomhola Grits," 1800 feet above 

 the top of the " Old Red," and where these grits are 3000 feet 

 thick. L. Scotoburdigalensis (distorted). 



Mr. Joseph Wright, F.G.S., has sent us a piece of " Carboni- 

 ferous Slate" from Shanbally, Cork, containing casts of a Cythere 

 (indeterminable) .
