On the under side of stones, and on the stems of Zoophytes, 
Cullercoats and Tynemouth ; common.—J. A. 
This species, though by no means uncommon between tide- 
marks, and occasionally in deeper water, has been, until lately, 
overlooked on account of its diminutive size. The bulbous 
swelling at the base of the stem has been very appropriately 
called bottle-shaped. It affords a good distinctive character. 
Mr. H. Goodsir observes that the propagation of Pedieellina is 
accomplished only by shoots coming directly from the root ; but 
I have met with two individuals of P. echinata, im which the ease 
was otherwise. In one, the young arose from the body of the 
animal, and at right angles to it ; im the other, from the stem a 
little below the body. These cases, however, are rare.
