What reading level is The Alcyonaria And Hydrocorallinae of the Cape of Good Hope book?
To quickly assess the difficulty of the text, read a short excerpt:
This species differs from all the known species of Sarcophy- tum in several characters, of which the more important are : — The constriction of the base, the colour of the spicules, of the tentacles, and of the coenenchym round the autozooids, the small size of the spicules (i.e., about one-tenth the length of the average of Sarcophytum spicules), and the relatively large size and prominence of the siphonozooids.
SUB-ORDER GORGONACEA.
One of the most difficult points in the morphology and class...ification of the Alcyonaria^ is the determination of a satisfactory boundary between the Alcyonacea and the Gor- gonacea. The present system is certainly not satisfactory, but as an improved one must depend upon the results of a series of observations which are not yet completed I have decided to adhere to it in this paper.
I have very little doubt that the genera Gorgonia, Juncella, Eunicella, Villogorgia, and Primnoisis are rightly included in the sub-order Gorgonacea, but I have considerable hesita- tion in separating Spongioderma and Melitodes from genera which are usually included in the Alcyonacea.
