In the other Alga? I have followed the classiiication adopted by Nordstedt in Fr. 

 Alg. N. Z. 1888, pretty closely, but in reverse order. 



Although not strictly within the scope of this paper, I take leave to mention certain 

 Alg®, (although sonie are marine,) published by Wittrock and Nordstedt in their erudite 

 and valuable Algae Exsiec., fasc. 1 — 20, 1877 — 1889, from the East of Asia. These are — 

 from East India, Rhizoclonium hieroglyphicum (Ag.) Ktz. f. calida (Ktz.) Wittr., No. 944; 

 Scytonema mychrous Ag., 673. From Ceylon, Pithophora polymorpha Wittr. 322; Chceto- 

 morpha obscura, Kjellm. 320; Ch. antennina (Bory) Ktz. 318; Conferva utriculosa Ktz. 

 ti Ceylanica Wille, 430; Sirogonium Ceylanicum Wittr. 358; Stephanocoelium verticillatum 

 Ktz. 347; Bryopsis tliuyöides Ktz. 348; Bry. pachynema v. Maktens (= Valonia con- 

 fervoides Harv.), 349; Caulerna clavifera J. G. Ag. 345; Caul. plumaris (Forsk.) Ag. 

 344; Chauvinia imbricata Kjellm. 346; and Ulva fasciata Delil. 432. From Burmah, 

 Euastrum obesum Josh. (q. v. ante), 813. From Java, JVostoc commune Vauch. 589- 

 From Borneo, Oedogonitim Kjellmanni Wittr. 306; Chlorodesmis pachypus Kjellm. 343; 

 Halimeda macroloba Decais. 339; and Hal. multicaulis Lamour. 341. From Japan, Chatto- 

 morpha crassa (Ag.) Ktz. A total of 21 algas; the above numbers referring to those in 

 the fasciculi of W. & X. 



The little fragments of Indian Utricularice, from the Stockholm Museum, kindlv 

 communicated by Prof. G. von Lagerheim, have proved of much interest, as from them 

 I extracted 74 species of micro-algae, representing 18 genera. Many of the forms were 

 neAv, besides others previously remarked by rne; in addition to which they also comprised 

 known forms not before noted from India. These, practically speaking, represen t 6 habitats: 

 East India, from Utricularia fasciculata; Eastern Himalayas, from U. stellaris; East Bengal, 

 from U. Jlexuosa; Malabar, from U. stellaris; British Burmah, from U. sp.; and Khasia, 

 upon the Brahmaputra River, from U. sp.; the Utricularias of the two latter habitats not 

 being named. This contribution is included in ni}- list, with the localities appended. 



One fact, concerning the Desmidiese of India, is noteworthy, viz. that in the great 

 majority of the plants which occur also in colder climates the Indian specimens are less 

 in size than their more frigid relatives, and for this difference it is difficult to assign a 

 cause. There appears to be great difference between the 'sporangial periods' of the Des- 

 mids and other Algae in various parts of India, as the time of the 'monsoons' varies very 

 much, and upon this the aquatic plants are dependent.
