Hab. On the roots of sea weed, about and beyond Low 

 water mark. Talland sand bay, Polperro, Lautivet and 

 Lantic bays. " Goran Haven," Mr. Peach. Port Pean, 

 Common. 



The appearance of this coralline, as Dr. Johnston has 

 said, " resembles a flock of hair with clusters of nits scat- 

 tered over it." The stem and branches are about the sizs 

 of hair, hollow, and spreading dichotomously, jointed, the 

 lower part of the joint pointed, the upper enlarged, and on 

 this enlarged part, the cells are arranged in companies of 

 from four to eight, and each cell is parallel to, and in con- 

 nection with the next. They resemble " Pan's pipes" in 

 miniature. The mouths of the cells are irregular,

Hab. Parasitical on the Sea-oak ; abundant about 

 October. 



This species climbs over fuci and corallines, by means of 

 its horny tubular fibres, and produces its cells at intervals, 

 either singly, or in clusters, of from three to eight. The 

 cells are large, and in shape resemble grains of wheat; they 

 are attached at one point below, and free at all the rest. 

 The aperture is terminal and closed. The polypes have 

 eight ciliated tentacula. When living, the cells are smooth ; 

 when dried, they become wrinkled, as Ellis has figured them. 



VALKERIA IMBRICATA. Confervoid, horny, irregu- 

 larly, but somewhat alternately branched; cells in irregular, 

 and dense clusters, sometimes in single rows, ovoid,
