For over 3 ycars l havc madc of the gcnus Licmophora as vvell 

 as of some allicd genera, such as Climacosphenia and a very in- 

 teresting new genus intermediate between Licmophora and Climaco- 

 sphenia, the subject of a special study and it is my intention to 

 publish a Monography of the family Licmophoreae, as soon as I shall 

 find some Magazine or Academy which will accord the hospitality 

 to my somewhat voluminous work. 



The genus Licmophora has been hitherto very much neglected 

 by the diatomists, as it can be seen from the fact that even with the 

 comparatively little material in my possession I bave been able to 

 find over 40 new species and varieties, thus more than doubling the 

 number of those abready known. My rather long experience on this 

 subject has brought me to the conviction that the genus Licmo- 

 phora is probably a very large one; I have but little doubt that 

 when it will be studied in ali countries, especially in the tropical seas, 

 as thoroughly as I have been able to do it in regard to the Mediter- 

 ranean, the Black sea and the Californian coast, the species and va- 

 rieties of this genus will by far exceed 100. 



In the following pages I will give a short description or diagnosis 

 of only 41 new forms, leaving some others, which require a further 

 examination, to another occasion. At the end of this note the reader
