504 CLEVE, DIATOMS. 
Actinocyclus Ehrenbergii Ralfs (Pritch. Inf. pag. 834) large 
and fine specimens. 
Asteromphalus flabellatus Bréb. (A. Schm. Atl. P1. XX XVIII, 
fig. 10—12). 
A. impar Shadb. (T. M. S. 154, pag. 17, Pl: L fig: 17)! 
V. Diatoms from Ceylon. 
During the stay of the Vega at Point de Galle Dr. Kjellman 
made some collections of marine alge. 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 rich. 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.

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

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