the living Bryozoan are protruded. In the central portion of the 
thallus they are always fused into a compact pseudoparenchymatous 
layer one or more cells in thickness, and it is only at the edges of 
the expansion that they are free. In many cases, however, the 
of life, and the union of the filaments into a membranous layer 
distinguish this genus from Goniotrichum, the irregular form of the 
layer from Hrythropeltis. ae enus is named after Mr. J. T. 
eeve, who, it may be rem a red, is also the original dis- 
coverer of Gonimophyllum Bufrhami, described in this Journal for 
1892 (p. 65, t. 319).

Hitherto botanists have not been agreed as to the identity of 
Carmichael’s Bangia ciliaris. Kiitzi ing thought it was a variety of 
Erythrotrichia carnea (= Goniotrichum ceramicola Kiitz.). Thuret, 
on the other hand, recognized in Porphyra Boryana Mont. the true 
B. ciliaris, while still more recently Berthold, not unnaturally, 
e. a a bs Sear to call E. Bertholdii for pire os 
Cro Hau and most other recent writers 
hesihstingty follow Thuret es uniting H. Boryana with B. ciliaris, 
h as a species of Porphyra. I am uncertain 
what the B. ciliaris of the Nereis Boreali- Seaiaieades really is, but 
the specimens from Bridgeport, Connecticut, distributed by Collins 
in the Phykotheka universalis no. 655, appear to me to be referable

Herbarium at Kew could clear up the matter, and I am much
