roundish outline extremely thin quite veinless cleft almost to 

 the base, the segments repeatedly divided in a manner more or 

 less between palmate and dichotomous mostly linear obtuse at 

 the ends, spots of granules in the segments. Greu. Crypt. Fl.

 rose-pink. 



2. N. pimctdtum, Grev. (dotted Nitophylluni); frond very thin 

 quite destitute in every part of veins vaguely cleft for half its 

 length or more into segments which become narrower as they 

 subdivide, spots of grannies scattered all over the frond. Grev.

 Summer. — This is surely very nearly allied to N.ocellatum; indeed I 

 can hardly distinguish, even fructified specimens, except by the more 

 generally diffused spots of seeds in the present species. 



3. N. ulvoideum, (Ulva-Iihe Nitophylhnn); frond thickish but 

 tender veinless roundish but very irregular in figure somewhat 

 cuneate at the base variously cleft into oblong more or less 

 broad segments rounded at the extremity, spots of granules 

 small scattered over nearly the whole frond. — Fucus ulvoides,

In the sea; coast of Moray, Mr. Brodie. Bantry, Mitt Hutchins. 

 Plymouth, Mitt Hill. Torquay, Mrt. Griffiths. Whitsand Bay, Mr. 

 Arnott. Miltown Malbay, Mr. Harvey. ©.— This is of a much 

 thicker texture than the preceding, more irregular in its circumscription 

 and of a deeper colour, verging on green when old. I have referred 

 Dr. Greville's N. HUHce to the Fucut ulvoides of Mr. Turner, because 

 Miss Hill's own specimens ami those of Mrs. Griffiths, exactly agree with 



a finer individual of Mr. Turner's plant in my 1 Icrbariiiin ; and MircU , tOO, 



with the figure above-quoted. '1'he two ladies now mentioned, have had 



the good fortune to find both kinds of fructification, namely, scattered 



dots of seeds and hemispherical capsules. 



•I. N. I ii>nm nmisniiii. (new (dtSCOtd .Mtopliylliim ); frond 



shortly stipitate extremely thin vaguely clefl the segments 

 roundish wedge-shaped, the stem vanishing at the base oi the 

 frond in a few obscure veins, fructification scattered orer the 

 frond. Grev, Alg. Brit, p. 81. — Delesseria BonnemauonH, Ag,
