acute axils, the apices laciniato-multifid ; " each lacinia terminated when 

 perfect with a pencil of minute confervoid filaments ; " "a net-work of 

 similar but branching filaments extends over the whole surface of the 

 frond, closely investing it, and to this network the fructification is 

 attached." — Phyc. Brit. Fmctification of two kinds on distinct indi- 

 viduals : 1, Pedicellate, oblong utricles, each containing about eight 

 spores, clustered in minute tufts, which are plentifully dispersed over 

 both surfaces of the frond, appearing like dots to the naked eye ; " 

 2, " Sausage-shaped or hnear, obtuse antheridia (?) attached to tufted 

 filaments, and scattered like utricles over the whole frond;" "they are 

 densely zoned with dotted lines." — Phjc. Brit. Structure loosely 

 cellular, central cells very large, oblong polygonal, smaller towards the 

 circumference. Substance cartilaginous, " at first crisp, but becoming 

 flaccid," and more or less adhering to paper. Colour, a dull yellowish 

 olive. 



This fine species is not unfrequently cast on shore on the southern 

 shores of the kingdom, and occasionally dredged on a hard gravelly or 

 shelly bottom in deep water. When obtained in a perfect state, the 

 narrow apices of the ultimate segments are beautifully fringed with 

 slender confervoid filaments, which are generally abraded in old plants, 

 and in specimens picked up on the beach. Its favourite habitat is on 

 old shells, often associated with zoophytes, to some of the flat species of 

 which, such as the Flust7'ce, it bears considerable resemblance. 



The name is commemorative of Miss Cutler, of Sidmouth, to whom 

 the botany of her own neighbourhood, as well as that of Britain in 

 general, is under many obligations.
