 alternately arranged, tubular, not contracted at tlie base aud 

 prolonged into the branch itself ; mouth somewhat patulous.

In the fifth volume of the 'Quart. Joura. Micr. Sci.' p. 173, 

 pi. 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 yery 

 characters on which the genus Cryptolaria had been established, 

 the hydrothecse 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 t}^e. It seems to 

 find its nearest relation in Grammaria ahietina (Sars), a species 

 which I cannot think Mr. llincks has done right in placing 

 in the genus Salacia of Lamouroux, the type of which has
