534 ZOOPHYTA. ESCHARADjE Hupothoa.Gen. LIV. HIPPOTHOA. — Crust adherent, interruptedand reticulated by branching and coalescing chains, formedof lengthened cells, united with each other at the extremities.137. H. catenularia.—Cells rounded anteally, taperingtothe other extremity, aperture oval.Tubipora catenularia, Jameson, Wern. Mem. i. 561 ?— On shells in deepwater, not uncommon.This species differs from the Hippothoa divaricata of Lamouroux (Zooph. 82.t. lxxx. f*.xv.), in the superior size and width of the cell at the anterior extremitythe margin of the mouth is ; slightly thickened and elevated ;thebranches proceed nearly at right angles, issuing from the margin beside themouth.Gen. ALECTO.— Adherent cells, nearly cylindrical,unitedwith each other at the extremities, and disposedin forkedbranches.1. A. dichotomy.— Filiform, mouth near the anterior extremity of the cells.Lamonr. Zooph. 84. t. lxxxi. f. 12—Geol. Eng. 214—In Oolite."FLUSTRAME.Gen. LV. FARCIMIA.— Ramose, branches cylindrical, jointed,with cells diverging from the axis.138. F.JiMtilosa.— Dichotomous, joints lengthened, cylindrical,with lozen-shaped impressed cells.Bugle coralline, Ellis, Coral. 46. t. xxiii.—Tubularia fistulosa, Linn.i. Syst. 1302 Cellularia salicornia, Pall. El. 61—Cellaria farciminoides,Sol. Ellis, Zooph. 26.— C. salicornia, Lamouroux, Cor. Flex. 126.Various parts of the coast, from Devon to Zetland.Height from two to three inches, diameter not exceeding the twentieth ofan inch ;the structure is tubular and proliferous ;the spaces between thejoints calcareous and brittle, the ceils internally are arranged round the axis,sublongitudinally, opening by a small orifice towards the summit of therhombic impression,Pallas states, as a proof of the rapid growth of this coralline,that he has seen specimens an inch and a half in height, growing onthe egg of a shark, containing an unmatured foetus.
