Actinia. 
glandular varieties, passing too into one another by such “ unper- 
ceived shades” that the limits cannot be distinctly defined. Nay, as 
Mr Teale has also noticed, I have seen specimens which were glan- 
dular on one-half of the body and smooth on the other, illustrating in 
a striking manner the inconstancy of the structure, and its subordi- 
nate value. 
In most systematic works on British Zoology there is an Actinia 
ejfceta , which is referable sometimes to this species, and sometimes 
to Act. maculata. The Act. effoeta of Linnseus, Syst. 1088, is found- 
ed on the “ Tertia Priapi marini sive Actiniae species” of Baster, 
Opus. Subsec. 143, tab. 14, fig. 2. This figure, is very unlike any 
variety of Act. gemmacea, or any other species with which 1 am ac- 
quainted. All the description Baster gives is this: “ Directas ilia 
habet in corpore strias, et inferne basin, sive marginem, qua se 
affigit.” 
5. A. dianthus, body cylindraceous , smooth ; oral disk 
marked in the centre with clavate radiating hands ; tentacula nu- 
merous ^ irregular , the outer small and forming round the margin 
a thick filamentous fringe . Ellis.

* Linnaeus quotes two distinct figures of Baster for his senilis, but as he sub- 
sequently refers to one of these figures for his effoeta, the other (tab. 13. fig. 2.) 
must be considered as representing the true senilis.
