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. 0,08 mm., everywhere provided with close radiant spines. Only one 
specitnen met with. It reminds somewhat of Podosira (Xanthiopyzis ?) 
spinoradiata Brun. (Temp. & Brun Japon tab. IV, fig. 10), found in ,Cal- 
caire de Yedo et de Jackson’s Paddock (trés rare)‘.
