P0LLIC1PES. Leach. m 
Gen. Char. Shell multivalved, laterally compress- 
ed, supported by a squamiferous peduncle; the 
five upper valves largest, the lower diminishing 
in size as they increase in number; apices of 
the valves free, pointed. 
This genus is distinguished from other cirripodous Mol- 
lusca by the squamiferous peduncle, the slightly curved 
lanceolate dorsal valve, the continued succession of small 
valves diminishing in size towards the peduncle, and the 
free points of all the valves. The most common recent 
species, P. Cornucopias, occurs in the Mediterranean in 
clusters attached to shells, &c. We have given a small 
figure of it.

Spec. Char. Valves marked with longitudinal, ele- 
vated striae. 
The central or terminal valve (fig. 1.) is elongated, 
rhomboidal; the posterior valve (fig. 2. & 7.) is arched, 
broad, lanceolate and subcarinated ; both are marked 
with irregular, sharply elevated, longitudinal strise : we 
have not recognized the other valves.
