512 ZOOPHYTA. GORGONIAD.E. Gorgonja. 
Ellis^ Cor. p. 61. t. xxvi. A. Lmn. Syst. 1293. — Cast ashore, Mount’s 
Bay, Cornwall, Borlase. — Leith shore, Mr John MacTcay. 
^ The axis is black, the cells minute, scattered, and occurring chiefly on one 
side. There is no satisfactory evidence that this species is indigenous to our 
rocks. The specimens which have been found among the rejectamenta of 
the sea, have probably belonged to some wrecked vessel from the West In- 
dies. At the same time, Mr Neill informs me that he saw Mr Mackay’s 
specimen shortly after it was found, and that it had all the aspect of being 
fresh and recent. 
74. G. anceps. — Subdichotomously branched, the branches 
free, compressed, with cells on each margin.

The axis is of a horny nature, inclining to leather. The cells are in rows.

The axis is ligneous. The branches are dichotomous, a little compressed, 
irregularly incurved, but rarely uniting. The flesh is full of denticulated 
spicula. The cells are conical, angular, and covered on the margin with 
little spines or pointed scales. It is probable that the references to Bay 
should be added to the following species, as Linnseus has done. 
76. G. verrucosa. — Margins of the cells denticulated.

Cornwall, Ellis, and Mr Devonshire, — Scotland, 
Sowerhy. 
The axis is woody, and the flesh granular. The branches grow in a flat 
fan-shaped manner, subdichotomous. The cells are crowded irregularly, and 
their margins are denticulated. In Mr Sowerby’s figure, one of the notches 
is represented as much larger than the others, forming about one-third of the 
margin. This appearance, however, is irregular, as in a specimen which I 
received from Mr J. D. C. Sowerhy, as the G. viminalis of his father ; the 
margin of the cells was regularly denticulated in some, and in others the large 
tooth was variable in the proportion of the margin which it occupied. Though 
this circumstance has been overlooked by preceding authors, there is little 
reason to consider it the indication of a new species, unless genuine speci- 
mens of G. verrucosa can be produced destitute of this character ; and there 
is no ground for considering it as the G. viminalis of Ellis. According to Ca- 
volini, the tentacula of the polypi are flat, tapering, and pinnated, and the 
body or head supporting these, protrudes considerably beyond the margin.
