of their tentacles capture and convey to the mouth such 

 varied creatures as prawns, small hermit-crabs, sea- 

 urchins, small fish, &c, the shells and other undigested' 

 portions of which are eventually ejected through the 

 mouth. 



Many Sea-anemones produce living young, which are 

 extruded from the mouth, and resemble the parent form 

 in all essentials. Others, such as the " dahlia wartlet " 

 or " crass " [Tealia crassicornis) and the " sand pintlet " 

 (Halcampa chrys ant helium), lay eggs which undergo 

 development in the surrounding water. The " snakelet " 

 (Anemonia sulcata) sometimes divides itself by a process 

 of " spontaneous fission " into two equal portions, each of 

 which becomes a perfect anemone. 



Fig. V. shows several of the more important kinds of 

 anemones found at Port Erin, most of which are 

 generally on view in the Aquarium. Actinia equina (or 

 A. 77iesembryanthemum), No. 2, is the common dark red, 

 smooth-bodied anemone which sometimes has a row of 

 bright blue spherules round the body at the base of the 

 tentacles. Metridium (or Actinoloha) dianthus (3) is the 

 plumose anemone, found at low tide attached to the blocks 

 of the old breakwater. It is generally of a pure white 

 colour, but pink specimens are sometimes found. No. 4, 

 Sagartia venusta, is a representative of a large group of 

 small anemones to which the brilliant red and white ones 

 of the Sugar-loaf Cave, and of the Clets in the Calf Sound, 

 and the cave-dwellers (S. troglodytes) of pools at Fleshwick 

 and elsewhere all belong. Halcampa chrysanthellum is a 

 siniill and simple form found occasionally, and Bunodes 



irosa (or H. gemmacea), No. 5, is a pink anemone 

 found in the pools, at Port Erin and easily recognisable 

 from its colour and the evenly roughened or papillose 

 surface of the body. The large "crass'' (Tealia
