PLATE XIYV., CIRRIPEDIA, ETC. 
Notation of the horizons, used below : 
Diy. 1e!. Horizon of Paradoxides lamellatus. 
Div. 1c?. Horizon of Paradoxides Eteminicus. 
Div. 1d'. Horison of Paradoxides Abenacus. 
Div. 1d?. Horizon of Paradoxides Davidis. 
Fic. 1. Stenotheca concentrica. Flattened and cracked along the back. 
Mag. 3. From Div. 1d', St. Martins, N. B. See p. 201. 
Fic. 2. S. concentrica var. radiata. Mag. 1°. From Div. 1e, St. John, N. 
B. See p. 202. 
Fic. 3. Stenotheca Hicksiana. Mag. +. From Diy. 1d', St. Martin’s, N. 
B. See p. 205. 
Fic. 4. Stenotheca triangularis. a, a cast of, showing the outline of the 
cone and the thickened apex. 6, a cast without the outline. Both 
mag. ¢. From Div. 1c’, St. John, N. B. See p. 203. 
Fic. 5. Strobilepis spinigera, J. M. Clarke. Terminal plate (and penulti- 
mate plate in outline). Figured for comparison from Dr. Clarke’s restora- 
tion. Mag. 3. The terminal plate is partly covered by the penultimate. 
Devonian species. See p. 203. 
Fic. 6. Stenotheca nasuta. a, small example, mag. $. 6, original type 
mag. ?. Both from Div. 1c, St. John, N. B. Seep. 204. 
Fic. 7. Plumulites Manuelensis, n. sp, mag. +. From Diy. 1d?, Manuel 
Brook, Newfoundland. See p. 200. (Misprinted Plate XY. on p. 200. ) 
Fia, 8. Cirripedian and other plates. Type A, a and b, two forms of oval 
plates. Type B, a, ribbed plate ; 6, smooth plate. Type C, a, plate with deep 
furrow ; b, plate with high umbo; c¢, plate with eared flange ; d, plate simi- 
larly flanged but more regular ; these are perhaps Cystidian. Type D, sym- 
metrical plate, perhaps one of the axial row of plates. Type E, triangular 
plate with radiating ridges (possibly cystidian). Type F, triangular plate 
with arched keel ( Cirropodites Cambrensis). Type G, triangular plate with 
facetted edges. All the figures except 8 G, a, mag. 7 8 G, a, is mag. $#. The 
narrow figures beside the larger ones are sections. See p. 206.
