SERPULA Aquaria* 



WATERING POT. 



Specific Character. Shell taper, straight, with 

 a convex disk at the summit perforated so as to 

 resemble the rose of a watering pot, having also a 

 radiated border : the colour is white with a slight 

 tinge of pale red or grey : the shell when perfect 

 is nearly a foot long, and more than an inch in 

 diameter at the dilated summit. 



This most singular and beautiful shell is rare ; 

 it is found in the East Indies. It bears a great 

 resemblance to the spout and rose of a watering 

 pot. It is now separated from the Serpulse 

 under the generic name Aspergillum.
