508 ZOOPHYTA. CARNOSA. Sarcinula. 



tions of these authors with the figures which they have given, and with spe- 

 cimens, leave no doubt of their identity- On this subject, indeed, Lamarck 

 appears to be singularly inaccurate. Under his Funiculina cylindrica (Hist, 

 ii. p. 423), which is the Pennatula mirabilis of Pallas, he quotes the figure of 

 Linnaeus, Mus. ad. ; and, under Virgularia juncea, the very same figure is 

 again referred to, and the copy thereof in the Philosophical Transactions. 



LAMELLIFERiE. 



Gen. SARCINULA. — Free, massive, consisting of vertical 

 parallel tubes, united by intervening matter. 



1. D. punctata Inferior surface concentrically undulated ; superior with 



cylindrical tubes, crenulated on the margin by subordinate pores, and divided 

 internally by transverse partitions. — Porpital Madreporite, Park. Org. Rem. 

 ii. 69. t. vii. f. 4 Gloucestershire and Staffordshire. 



2. S. angularis Inferior surface with diverging strise ; superior with crowd- 

 ed polygonal tubes — Porpital Madreporite, Park.^rg. Rem. ii. 69. t. vii. f. 3. 

 — Dudley, Staffordshire. 



Gen. LITHOSTROTION.— Coral of aggregated prismatical 

 parallel tubes, with single terminal stellular discs. 



1. L. striatum Hexangular ; striated longitudinally ; slightly waved 



transversely ; each plane with about ten striae ; the rays of the star unite with 

 a small solid central dixxs.—Luid. Lith. 122. t. xxiii. Park. Org. Rem. ii. 43. 

 t. v. f. 6, 3. — In Carboniferous Limestone. 



2. 1j. floriforme. — This chiefly differs from the preceding in its greater size, 

 and the axis occupying a greater space ; to which Martin adds, " centres pro- 

 jecting, pointed, and writhed or twisted like a rope." — Mart. Derb. t. xliii. 

 44. In Carboniferous Limestone. 



3. L. oblongum Pentangular, striated, the stems about one-twentieth of 



an inch from each other ; the rays diverge from the centre, branching towards 

 the circumference. Park. Org. Rem. ii. 56. t. vi. f. 12, 13 — Oolite. 



4. L. marginatum. — Hexangular ; each angle with a raised rib, and numer- 

 ous distant, small, short obtuse processes ; the planes flat and smooth ; the 

 star consists of plates from the centre to each angle, with a few transverse 

 ones. Two detached columns of this species, about the tenth of an inch in 

 diameter, have occurred to me in Carboniferous Limestone. 



Gen. XXIX. CARYOPHYLLEA.— Turbinated or cylin- 

 drical, simple or branched, adhering by the base to other 

 bodies. 



70. C. cyatkus. — Primary lamellae of the star about forty in 

 number, widi intermediate smaller ones, and a prominent curved 

 centre. 



Madrcpora cyathus, Sol. Zooji. 150.— C. cyathus, Flem. "Worn. Mem. ii.
