CLEVE, DIATOMS. 



Adinocyclus Ehrenhergii Ralfs (Pritch. Inf. pag. 834) large 

 and fine specimens. 



Asteroniphalus flabellatus Breb. (A. Schm. Atl. PI. XXXVIII, 

 fig. 10—12). 



A. impar Shadb. (T. M. S. 154, pag. 17, PI. I, fig. 17). 



V. Diatoms from Oeylon. 



During the stay of the Vega at Point de Galle Dr. Kjellman 

 made some collections of marine algse. On cleaning them he 

 collected the washing a water deposits, which were given to 

 me for examination. Also some samples of marine coarse 

 mud were taken and sent to me. The latter ware very poor 

 in diatoms, but the first named deposit tolerably I'ich. On 

 the marine diatoms of Ceylon we have by Dr. Leuduger 

 Fortmorel an elaborate paper, containing descriptions of 

 many new forms *. The samples collected by Dr. Kjellman 

 contained scarcely. any of the species described by Dr. Leuduger- 

 Fortmorel, but a lot of forms not recorded in the named paper. 

 The collection of Dr. Kjellman completes in a welcome manner 

 the number of marine species, known from Ceylon. I think 

 it will be most convenient to enumerate the forms, contained 

 in the samples from the Vega-Expedition, in the same order as 

 in the paper of Dr. Leuduger-Fortmorel. I have added a * 

 to each species not found by Dr. Leuduger-Fortmorel. 



Cocconeis Scutellum Ehb. (Van Heurck Syn. PL XXIX, fig. 

 1—12).

A. pennata Grev. — One single valve of an Achnanthes, 

 which I believe belongs to A. pennata, was found in the 

 Ceylon-material, but having had no occasion to see the fig.
