glandular varieties, passing too into one another by such " unpei*- 

 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 

 effcetay which is referable sometimes to this species, and sometimes 

 to Act. maculata. The Act. effceta of Linnaeus, 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 I 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.

* Linnieus quotes two distinct figures of Baster for his senilis, but as he sub- 

 sequently refers to one of these figures for his effceta, the other (tab. 1 3. fig. 2. ) 

 must be considered as representing the true senilis.
