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 j 
the rim of the mouth (fig. 3) is occasionally protruded as a 
conical process. 
This form exhibited none of the “ remarkably vigorous and 
spasmodic contractility ” ascribed by Mr. Gosse to the family ; 
for it was comparatively inert.

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. Beau temp sit, De Quatref.*, but is 
distinguished by the marks on the tentacles, which in the 
latter only have the tip 11 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.

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 papillae at one end. No cilia were present; so 
that in all probability they were dead. Both examples had
