Gen. TEREBEIXARIA. — -Branched, spirally twisted ; pores 
tubular, disposed spirally.

obtuse.— -Lawzowrotto?, JZooph. 84, t. Ixxxii. f. 1. Geol. Eng. 214.— 
ESCHAHAD.^. 
Gen. L. ESCHAR a. — F rondescent, with a single layer of 
cells on each side. 
124. E. retyvrmis,-—V\ditQ^ broad, winding, uniting irregu- 
larly.

English coast. 
In masses from a few inches to upwards of a foot, formed, by the union of 
the plates, into irregular cavities ; surface rough, the orifices of the cells are 
round, usually with a blunt tooth on one side, the intervening spaces rough. 
125. -Expansions narrow, compressed, branch- 
ed, occasionally united. 
Italian coral, Ellis, Coral. 72, t. xxx. f. 6 — E. fasc. Pallas, El. 43.— 
English coast. 
This chiefly differs from the preceding in being branched, and the divi > 
sions being flat and narrow. In the opinion of Pallas it is only a variety. 
Gen. LI. RETEPORA. — Expanded, with regular openings, 
forming a net- work ; cells on the upper side. 
126. R. reticidata.—^ou^\ on both sides, the divisions 
rounded ; the cells with the orifices declining, and protected by 
a spinous process on the central margin.

Syst. i. 1284. Fah. Faun. Gr. 433. — Coral, Cordiner, Ruins, t. No. 6. 
— In deep water. 
Expanding to the extent of two or three inches ; more or less cup-shaped, 
waved, uniting ; the holes are oval, regular, the intervening spaces support-
