Fam. XLYIII. — Bullidjs. 
137. Tornatella fasciata, rare. 
138. Scaphander lignariu's. 
TUNIC AT A. 
Fam. — A sciDiATiE. 
139. Ascidia mentula. I found a very fine one attached to a 
piece of slate, at a very low tide : it was nearly six 
inches long. 
140. Ascidia sp. Several other forms have been seen, but not 
taken for preservation. 
Crustacea . — Upon further exploration it has been found 
that the shrimp is a very rare species all along this coast, 
but that the prawn, Palcemon serratus, is very abundant. 
The fishermen firmly believe that the lobsters and crabs 
are sensitive to coming violent changes in the wind and 
weather, and maintain that they forsake the neighbourhood 
of the rocks in the bay and go far out into deep water in 
the channel 24 to 48 hours before the storm breaks on the 
coast ; for none are ever caught in the ports a day or two 
before the storm. That fishes leave the shallow waters 
of the bay for deeper water before a storm, is a fact for 
which I can myself bear testimony, as well as the fact 
that on warm quiet days and nights, when the water is oily 
and without a ripple, the fish frequent the bay in thousands. 
The Crustacea, Balanidae, Lepadidae, Annelidas, Echino- 
dermata, Actinozoa, are only at present half ascertained, but 
a sufficient number of specimens have been obtained to 
make their further collection important ; and these, toge- 
ther with the land and fresh-water shells, will be given in 
a future list of the fauna of Cymmeran.
