216 MISS Е. S. BARTON ОХ THE GENUS TURBINARIA. 
ngly criticised the value of the specific characters adopted by his predecessors, 
with the result that he established among others a species, /7. denudata, which made 
confusion worse confounded; it has now disappeared into the limbo of synonymy. J.G. 
Agardh first really introduced order into the genus (Spec. Gen. et Ord. Algarum, p. 265), 
and Kützing (in the * Tabulze Phycologicee,’ Bd. x. p. 24) followed in his path, raising 
certain of the Agardhian varieties to specific rank. Briefly, my present contribution to 
our knowledge of Turbinaria recognizes and maintains the work of Agardh and Kützing, 
with the exception that one of the Agardhian varieties adopted as a species by Kützing 
now disappears, together with another species of Kützing; and, moreover, І have ventured 
to describe three new species and two new varieties of this small genus, which I hope 
may not be considered an extravagant addition. The species and varieties are all 
very closely connected with each other, and it is possible to determine them only after 
minute examination. Herbarium specimens should be moistened in warm water to 
exhibit the winged and dentate characters. In the British Museum, besides Sloane’s and 
Forskál's specimens, I have examined material collected by Harvey and by Ferguson in 
Ceylon ; by Mr. Thurston in the Gulf of Manaar; by Dr. Falconer at Mangalore ; by an 
unknown collector (herb. Dickie) and Dr. Prain in the Andaman Islands; by Schimper 
and by Sir Gardner Wilkinson, in the Red Sea, and also specimens ex herb. Hohenacker 
from the same basin ; by Hildebrandt on the Somali coast and Madagascar; from Agalagas, 
ex herb. Montagne; by Colonel Pike in Mauritius; from Пе de Bourbon, ex herb. 
В. Brown; from Seychelles by H.M.S. * Alert’; by Balfour from Rodriguez; from Torres 
Straits by Prof. Haddon ; from New Guinea by Capt. Sir E. Belcher; from Australia by 
Robert Brown, Sir Ferdinand von Mueller, and by Labillardiére ; from Mangaia by Rev. 
Mr. Gill; from the Friendly Islands by Capt. Sir E. Home; from other Pacific Islands 
by H.M.S. ‘Challenger’; from the West Indies by M. Mazé. At the Herbarium, Royal 
Gardens, Kew, I have seen also specimens collected at Diego Garcia by Mr. Bourne; at 
Madras by Wight; at Macao ex herb. Hooker; at Samoa by Powell; at Howick's Group 
by Sir F. von Mueller; and at Swan River by Lady Broome, besides the specimens of 
Dawson Turner, of such historical value. 
Mevrouw Weber van Bosse has with great kindness sent me her collection made by 
herself in the Malay Islands, and from it I have described one new species and two new 
varieties, one of the latter bearing her name. 
The other two new species were described from material in the British Museum, but 
one Mars from a unique specimen. However such is the value of Mevrouw Weber van 
Bosse's colleetion that I have found in it additional specimens of this interesting and 
rare Turbinaria. I wish to record my great indebtedness to her for her help with 
material, and my sense of her kindness.
