270 BOPYRIDA. 
we have always found that which we consider as the 
male animal to be free, and roaming distantly from its 
supposed mate. The cirriped which it infests (Balanus 
balanoides) is a gregarious species, and lives upon the 
rocky shore between the tidal marks, and we have fre- 
quently seen, on breaking off a mass of the Balani, the 
little red crustacea run away, and the paucity of the 
males that we observed in comparison with that of the 
females, has induced us to consider that the male wanders 
about from one cirriped to another. The animal is of 
a red-brown colour, and is an active little creature. 
The female, in its adult state, is a large inert inarticulate 
mass, destitute of antennz, mandibles, or foot-jaws, legs 
or branchial appendages, with the body dilated on each 
side into three large rounded or conical lobes, the tail 
itself forming a terminal lobe similar to the others. In 
Dr. Buchholz’s specimen the body (probably from having 
been immersed in spirits) was of a broader and rounder 
form than in our figure, with the lobes more conical and 
more regularly radiating, giving the animal more of a 
star-like appearance. It is furnished with a short mouth 
or sucker, by which it affixes itself to its prey. 
The young animal, as described by Buchholz, or the 
male as suggested above, is elongate (more ovate in 
Buchholz’s figure than in our own), with the head as 
wide as the following segment, which, as well as the 
remaining segments of the body (and also of the tail, 
according to Buchholz), have the lateral margin deflexed, 
with its posterior margin serrated. The mouth consists 
of a conical process, protected above by two flattened 
plates, of which the posterior margin is serrated. The 
minute pair of upper antennz are affixed at the sides of 
these appendages, and consist of a strong basal joint, 
thickly fringed with long seta, and a terminal articulated
