Long. 76—120, lat. centr. 11—12, lat. apie. 14 ,u. T. XX, f. 3. 



Hab. Ut supra. (I have also observed this species in an American gathering, 

 kindly sent by the Rev. Fr. Wolle). My friend Dr. Nordstedt asks, »Are you sure 

 it is not an Oedogonium, near Oe. punctostriatum»? I do not know the Oedogoniuin 

 referred to! 

 5. G. pilosum, Wolle. (Desm. U. S. A. p. 22, t. I, f. 2, 1884). Hujiis speciei formas 

 duas observavi: 



a. forma minor, n. f. Long. 120 — 150, lat. centr. 8 — 9, lat. apie. 9 — 10, long. spin. 4 — 5 k. 



b. » evoluta, n. f. » 160-225, » » 11—12,» » 13 — 14, » 6—6.5//. 



This is but a large and highly developed form. 

 T. XX, af. 1; b f. 2. 

 Central India. 



Note. It seems a remarkable fart that HiLSE (in Kirchner's Algen in Kr. Flor. 

 Schles. p. 131, 1878) and West (Fr. Alg. West-Yorkshire, Journ. Bot. t. 291, f. 6, 1889) 

 have given, irtdependently, the same name to the same species of this genus, G. Iceve! 

 The counterpart of this event occurred, when Brébisson and Ralfs both, also indepen- 

 dently, had stvled a Oosmarinm C. quadratum! (Jfr Ralfs Br. Desm. p. 93. 



The synonymy of G. Ralfsii seems a little abnormal. If the laws of priority in 

 Botanical naraes are inexorahle, then this species must be G. monotsenium. It seems but 

 proper that a specific name should be protected from useless or capricious alteration by 

 others, but may not the original author change it? 



Moreover, De Bary's original definition of the genus was altered by him two years 

 afterwards, and Genicularia excluded; this being so, it seems that the illustrious author only 

 exereised an undoubted right in re-naming his own species, under new generic conditions. 



Gen. 9. Tetmemorus, Ralfs. 

 (Ralfs, Ann. & Mag. Nat. Hist. vol. XIV, p. 250, 1844.) 



1. T. Brebissonii, Ralfs (1. c. p. 257, 1844; Br. Des. p. 145, t, XXIV, f. 1, 1848; Clo- 

 sterium Brebissonii, Mengh. Synops. p. 236, 1840), forma inter /i minorem De Bary 

 (Conjug. p. 73) et Ii atteimatum Nordst. (Fr. Alg. X. Z. p. (56, t. III, f. 18). Long- 

 100,' lat, 22, lat, isth. 15 ,«. T. VII, f. 9. 



Northern India; the only specimen I observed of this genus; Dr. Wallich has 

 seen others, but has not noted or tigured them. 



(Tetmemorus granulatus (Bréb.) Ralfs, is noted by Roy in Dickie's 'Notes on 

 Algie from the Himalayas' (Linn. Soc. Journ. Bot, vol. XIX, p. 231, 1882), from över 

 15,000 feet alt.). 



Gen. 10. Triploceras, Bailey. 



(Bail. Micr. Obs. in 'Smith. Träns.' p. 37, 1850). 



1. Tr. gracile, Bail. (1. c. p. 38, t. I, f. 10; Docidium verticillatum, Bail. in Ralfs' Br, 

 Desm. p. 219, t, XXXV, f. 9 e; Do»: gracile, Wittrock Skand. Desm. p. 21, f. lo. 

 1869; Doc. pristidce, Hobson, Notes, p. 169, cum tig. 1863). 



Forma a. elongata, n. f. Paullo longior quam f. typica; lobi apicales 3, bidentati, di- 

 vergentes, modice producti; semicelluhe prominentiis verticillorum 14 — 16
