In a sample from KMn — GLt I found a Campylodiscus agreeing with

 KKt, TK, s.l. (4 samples). 



Area: Europe. Malay Archipelago. 



In a sample from KKt I found a form (Tab. nostr. II, fig. 34) which, 

 if it really is a Diatom — and not only a spore — must probably be 

 referred to Xanthiopyxis Ehr. The propositions are: L. c. 0,06 mm, 

 b. c. 0,03 mm., everywhere provided with close radiant spines. Only one 

 specimen met with. It reminds somewhat of Podosira {Xanthiopyxis ?) 

 spinoradiata Brun. (Temp. & Brun Japon tab. IV, fig. 10), found in „Gal- 

 caire de Yedo et de Jackson's Paddock (très rare)".
