Zoophyta. 
Zoophytes are, on the whole, scarce in the Aigean. They seem to suffer 
the same diminishing influence as to size with the Mollusca, very numerous 
minute specimens occurring of Corallium rubrum, for instance, but none 
being met with of sufficient size as to render them of value in commerce. 
Corallines are scarce, a very few species only being common, among others 
Farcimia fistulosa, Flustre are very rare ; incrusting corallines frequent. 
The only corals met with of any size were Cladocora cespitosa and Porites 
dedalea, The former is extremely abundant near water-mark on the coast 
of Asia Minor, where it forms elegant cauliflower-like patches of bright 
orange, from the hue of the animals, adhering to the rocks. The latter is 
rare, and was dredged alive in about 12 fathoms in the Bay of Serpho. 
Among the soft Zoophytes there are several beautiful and curious species 
inhabiting the AXgean. In all six species were met with, of which one, the 
Edvardsia vestita, was remarkable for living in a tube of its own construc- 
tion, formed of gravel and shells; and another for living entirely on the sur- 
face of the ocean, where it was frequently met with swimming during the 
winter months. 
Aleyonia were not uncommon, but no species of Pennatula was met with, 
nor of Gorgonia*. 
The range of Zoophytes is very great in the Aigean, extending nearly to 
the greatest depths explored. A beautiful little waxy green Jdmonea? was 
characteristic of depths below 100 fathoms, extending to 180. Caryophyllia 
(cyathus) ranged from 5 to 90 fathoms. Hornera at 40. Plumularie ranged 
to 40. Myriapora truncata was found as deep as 70 fathoms alive. Zubu- 
* Two species of Pennatula have since been procured in abundance off the mouth of the 
Hermus in 7 fathoms, by Lieut. Spratt.
