Diatomaceer fran Spetzbergen (Idem, 1864). 



Diatoms collected during the expedition of the " Vega " examined by 

 P. T. Cleve, 18S3, with 4 plates. Very important work. 



The diatoms of Finland; Helsingfors, 1S91, 8vo., with 3 plates. 



Professor Cleve has published a large number of pamphlets, which 

 will be found enumerated in Deby's work. Mr. Cleve has just completed 

 a monograph on the Raphidieae. This work, which is the result of 

 prolonged study, will finally reduce to order those enormous groups called 

 Amphora, Cymbella, Navicula, Amphiprora, Cocconeis, etc., in which the 

 diatomist has experienced so much difficulty in classifying.

Analysis of the Diatomaceous genus Campylodiscus, published for 

 Julien Deby, London, 1S91, with 15 plates (phototypes). An excessively 

 important work which has liberated the genus of the confused state 

 in which it had previously been.

This important work forms the introduction to the work of De Toni. 

 Some copies as a separate work have been distributed.

Sec. III. Crypto-raphideae Patavii, 1894. 



An indispensable work for the general study of species which have 

 hitherto been named. It should find a place in the library of every 

 earnest diatomist. There will be found in it an exact account of all 

 forms established by various authors, together with a reference to 

 localities, pages and figures, and a good description whenever sufficient 

 information has been given to connect the form.
