the three following segments are much larger and wider, 
with the sides ending in acute recurved processes; the 
fifth segment is as long as the preceding, but abbreviated 
at each side, and the sixth is obtusely triangular. 
We have received it from Polperro, where it was taken 
by Mr. Loughrin, and there are specimens in the British 
Museum from Ireland that have the caudal termination 
more pointed than in our figure.
