I.— Observations on the Structure and Reproduction of Eleutheria, 
Quatref.* By Dr. A. Krounf. 
MR. HINCKS has recently communicated, in the ‘Annals and 
Magazine of Natural History’ (3 ser. vol. vii. p. 73), some ex- 
eeedingly valuable observations on Hleutheria, which are of 
especial importance, because they finally solve the question 
which has hitherto remained in suspense, as to the origin and 
position of this remarkably beautiful Coelenteran. For although 
Van Beneden and Dujardin had already raised many well-founded 
objections against the opinion of its discoverer (who associated 
Hleutheria with the Hydrina), recognized its relationship to the 
Medusz, and conjectured that it originated from a Medusan or 
Hydroid polype, the latter still remained to be discovered{. In 
this Hincks has succeeded. .The parent stock on which Eleutheria 
is produced as a bud belongs, according to Hincks, to the fa- 
mily Coryniade, in which it represents a new genus and species 
—Clavatella prolifera.
