38 MARINE FAUNA OF ST. ANDREWS. 



disk (Plate VII. figs. 1 & 2). The latter is marked by 

 eight alcyonarian divisions or radii, and has always a 

 ragged border of the investing sheath. The disk has a pale 

 brownish colour. 



The tentacles (Plate VII. fig. 4) are simple, rather blunt, 

 pale and translucent, with a white streak in the centre; 

 the rim of the mouth (fig. 3) is occasionally protruded as a 

 conical process. 



This form exhibited none of the " remarkably vigorous and 

 spasmodic conti-actiUty " ascribed by Mr. Gosse to the family ; 

 for it was comparatively inert. 



Edwardsia Ooodsiri, M'l., Proc. Eoy. Soc. Ed. 1864-5. 

 [Plate n. fig. 4.] 



Found at the same time and place with the former. Ten- 

 tacles 15, translucent, longer than the diameter of the oral 

 disk, and not much tapered (Plate VII. fig. 6). A whitish 

 ring occurs at the tip of each ; and from the base a white 

 spear-head with a transparent centre reaches more than half- 

 way up (fig. 7). Oral disk streaked with white and brown. 

 It is somewhat allied to E. Beautempsii, De Quatref.*, but is 

 distinguished by the marks on the tentacles, which in the 

 latter only have the tip " d'un beau jaune rougeatre." The 

 posterior end of the example (fig. 5) was often fixed to the 

 glass by its ectoderm, which apparently had very minute or 

 granular suckers. 



Swarms of an Edwardsia occur in the stomach of the 



flounder. 



Genus 6. Cerianthus, Delle Chiaje. 



Cerianthus Lloydii, Gosse, Brit. Anem. p. 268, pi. 7. fig. 8, 



and woodcut, p. 269. 



Procured at low water from the margin of the East Rocks, 



and occasionally thrown on the West Sands after storms. A 



splendid specimen from the latter (measuring 7| inches long 



and as thick as a finger) in February discharged a^ vast 



number of ova after a week's confinement. The majority of 



these ovoid bodies were rather coarsely granular ; and some 



had minute papllliB at one end. No cilia were present ; so 



that in all probability they were dead. Both examples had
