In the fifth volume of the ‘Quart. Journ. Micr. Sci.’ p. 173, 
pl. xvi., Busk established a genus Cryptolaria for the reception 
of a New-Zealand Hydrozoon, which had the peculiarity of 
having the “cells completely immersed in a cylindrical poly- 
pidom composed of numerous tubes.” In the following year 
he described another Hydroid from Madeira under the name 
Cryptolaria exserta ; but this species was devoid of the very 
characters on which the genus Cryptolaria had been established, 
the hydrothecze being much exserted, and standing out at a 
considerable angle from the stem. Many specimens of this 
Madeiran form are among the cable-scrapings ; and they agree 
in every respect with Busk’s description and figures, except 
that they are much less regularly branched than is represented 
in his plate xix. fig. 3. It is impossible that this species can 
"remain in the same genus with C. prima; and I therefore con- 
stitute a new genus, of which it will be the type. It seems to 
find its nearest relation in Grammarta abietina (Sars), a species 
which I cannot think Mr. Hincks has done right in placing 
in the genus Salacia of Lamouroux, the type of which has
