of the frond, closely investing it ; and to this net-work the fructification is 

 attached. Fructification, of two kinds, on distinct individuals ; 1, pedi- 

 cellate, oblong idricles, 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 linear, obtuse 

 antheridia (?) attached to tufted filaments and scattered, like the utricles, 

 over the whole frond. They are densely zoned with dotted lines. Substance 

 cartilaginous, at first crisp, but becoming flaccid ; and then, on pressure, 

 closely adhering to paper in drying. Colour a foxy olive. Structure very 

 lax, the cells of the interior being few, of great size, and colourless. 



Cutler ia multifida was discovered at Yarmouth by Mr. Dawson 

 Turner, in August, IS 04, and first described in English botany 

 by Sir J. E. Smith. Although found on many parts of our 

 coasts it is still considered a rare species, partly, perhaps, from its 

 place of growth being beyond the limit of ordinary tides. Occa- 

 sionally, after stormy weather, it is washed up in some plenty. 

 The most abundant habitat yet discovered, is at Roundstone Bay, 

 where, last summer, Mr. Mc' Calla dredged a large quantity in a 

 remarkably fine state. 



This beautiful plant was selected by Dr. Greville to comme- 

 morate the services rendered to British Botany by Miss Cutler, 

 of Sidmouth, whose explorations of her neighbourhood have 

 amply earned " the highest compliment that one botanist can 

 bestow on another." No genus can be more distinct, and few, 

 among the Dictyotea, have a more delicate or curious structure. 

 The fruit is very remarkable. The antheridia, described by 

 Dr. Dickie in the f Annals of Natural History ', I have only ob- 

 served on a specimen sent me by Miss Cutler many years since, 

 but similar bodies appear to be commonly borne by the exotic 

 C. adspersa, on my specimens of which species I can find no 

 other fruit. They bear a striking resemblance to the silicular 

 fruit of Uctocarpus, and perhaps are organs of a similar nature. 



Four species of Cutleria are described, with three of which 

 only am I acquainted. Our C. multifida is found on all the 

 coasts of southern Em-ope ; C. laciniata (which I only know by 

 name), on the French coasts ; and C. atispersa and partialis in 

 the Mediterranean. The two latter are very like each other, if 

 they be really more than varieties of one species, but both are 

 abundantly distinct from C. multifida, though evidently belonging 

 to the same natural genus.
