1. On the Reproduction of Turris neglecta. 
The only observations that we have as to the reproduction - 
of the gymnopthalmatous Medusae are those of Mr Gosse with 
regard to Turris neglecta. He is the pioneer who first ac- 
tually witnessed, or rather caught a glimpse of, the reproduc- 
tion of a hydroid zoophyte from a recognised species of Me- 
dusa. In September 1852, he saw the oval purple gemmules 
of Turrfs neglecta escaping from the walls of the ovaries, and 
dropping down to the bottom of the vessel in which they were 
confined, where they moved slowly about by means of their 
vibratile cilia. He placed a number of these gemmules in a 
properly-constructed cell, and, by watching them, ascertained 
the following facts : — " The gemmule (says he) having ad- 
hered to the glass, grows out into a lengthened form, vari- 
ously knotted and swollen, and frequently dividing into two 
branches, the whole adhering closely to the glass. After a 
day or two's growth in this manner, a perpendicular stem 
begins to shoot from some point of this creeping root, and 
soon separates into four straight, slender, slightly divergent 
tentacles, which shoot to a considerable length. The little 
creature is now a polyp of four tentacles." At this stage 
they all died, and he never succeeded in repeating his ob- 
servations. In August last, I picked up at Queensferry a spe-
