nulate and convex. The snb-umbrella is about half the height of the 
disk. The central stomach is exceedingly simple in structure, apparently 
consisting of two regions, from the upper of which issue the gastro-vas- 
cular canals, which vary in number from eight to twelve, according to 
the size and age of the specimens selected for examination. The marginal 
tentacles are very numerous, and highly contractile, each springing from 
a pale tawny bulb, at the upper part of which is situated a conspicuous 
ocellus, of a black, or rather, perhaps, intensely dark violet, colour. To 
the naked eye these ocelli are invisible, but they serve to impart an ex¬ 
quisite roseate tinge to the margin of the disk. The reproductive glands 
occur as thickenings in the radiating canals, being usually placed in the 
neighbourhood of the central peduncle. It is probable that this Equorea 
is identical with some one of the numerous foreign species of the genus 
described by Peron, or Quoy and Gaimard; but the descriptions given by 
these authors, too often scanty and insufficient, together with the im¬ 
possibility of obtaining access to the plates of Peron and Lesieur, renders 
this point difficult of determination. This Medusa is gregarious, occur¬ 
ring in considerable numbers in those localities where its presence has 
hitherto been detected. In size it^does not exceed one inch in diameter. 
Dr. Carte exhibited a living specimen of the Lepidosiren, obtained 
by Lieutenant Dun from the Diver Gambia. 
Some conversation then ensued, in which Drs. Carte and Kinahan

Dr. E. Percival Wright read Notes of an Entomological Tour in the

The Association then adjourned for the Session.

ON AN ANCIENT INSCRIPTION SUPPOSED TO BE IN THE ETRUSCAN LANGUAGE. 
Donaldson, in his “ Yarronianus,” pp. 126, 127, gives an inscription 
which he conceives to be Etruscan, in which the Pelasgian element pre¬ 
ponderates ; and he proceeds, in a note, to offer suggestions for explain¬ 
ing it upon that supposition. In consulting his work for etymological 
purposes, it struck me very forcibly that the words of this inscription,
