 ofthe "Sealark" Expedition. (Trans. Linn. Soc. London.

The present paper continues and concludes the report on the 

 marine algae of the Sealark Expedition to the Indian Ocean 

 which was begun by Mr. and Mss. Gepp. (vide Centralbl. Bd. CXI. 

 p. 55). 



Over 80 species of Florideae are dealt with. A large number of 

 reef species were found during the expedition, but most of the 

 novelties were dredged from deep water. The latter, which com- 

 prise 1 new genus and 17 new species, are as under: Chantransia 

 liagorae Gloiophloea? articulata, Polycoelia van Hoevellii, Eucheutna 

 Cottonii, Gloioderma ? expansa, Chylocladia perpusilla, Laurencia 

 pygmaea, Pseudendrosiphonia Gardneri gen. et sp. nov., Chondria 

 simpliciuscula, Oligocladus Prainii, O. pusillus, Dasyopsis Stanleyi, 

 D. aperta, D. Geppii, D. palmatiftda, Tapeinodasya Ethelae, Hetero- 

 siphonia Rendlei, Peyssonnelia biradiata. In addition to this a new 

 genus Amphisbetema is formed for the reception ot Dasya indica, 

 J. Ag., and Tolypiocladia glomerulata is removed to the genus Roschera, 

 Schmitz. 



With regard to the systematic list and summary of distribution 

 (p. 107 — 110) it should be noted that the original pages have been 

 cancelled, and should be replaced by the corrected pages issued 

 with Trans. Vol. VIII, part. 4. A. D. Cotton.
