Many specimens of this remarkable little ostracod were 

 found by washing waterlogged and decayed wood in weak 

 spirit, and examining the sediment. This appears to be 

 the true habitat of the species. My father, who first 

 found the species in material dredged in the Clyde, tells 

 me that he always finds it when examining the sediment 

 washed from old wood brought up in the trawl net, and 

 remarks that it seems to be partial to that kind of habitat.
