Hah. — Loch Dow, near Loch Glow, Kinross-shire, 14th 

 September 1889. This is still the only record I have of 

 P. euplectella from the district under consideration. It is 

 the most beautiful of the species belonging to the British 

 Candonaz. The shell is cylindrical and very tumid, and its 

 structure is suggestive of the glass-sponge Ewplectella, as 

 implied by the specific name.
