In a paper upon the Indian Alg?e, by Drs. Zeller and Rabenhorst, in the Journal 

 of the Asiatic Society of Bengal, vol. 42, pp. 175 — 193, 1873, a few stray Desmids (eol- 

 lected by Mr. S. Kurz in Arracan and British Burmah) only are mentioned, viz. Chs. 

 striolatum, Eiir.; Pleurot. baculum, (Breb.) DBt.; Pl. trabecula (= Doc. Ehrenbergii Rlfs. 

 non D. trabecula, Ehr.); Enastrum ansatum, and E. ampullaceum, Ralfs. The raain 

 portion of Mr. Kurz' Desraid- gatherings was sent to Mr. W. Archer, of Dublin, and is 

 yet unpublished. 



A brief meraoir by Dr. G. Dickie of Aberdeen, 'Notes on Alga^ from the Himalayas', 

 appeared in the Linnean Soc. Journ. Bot. Vol. XIX, pp. 230 — 232, in 1882. In this the 

 Desmidiea? are determined by Mr. J. Rov, viz. Hy al. dissiliens v. tridentula, Nordst.; 

 Cos. Brebissonii, Mengh.; Cos. pachydermum, Lund., Tet. granulatus, Breb.; Cyl. Brebis- 

 sonii, Mengh.; and Penium digitus Ehrb.; together with 7 new species, which as yet are 

 not described. Most of these AlgaB were from great altitudes, 15,000 to 18,000 feet!
