There are granulations on the middle of the segments in 
Porcellio vatzeburgu and the sides of its body are more nearly 
parallel than in the other species of Porcellio ; 
the frontal lobe is, practically speaking, semi- 
circular and the lateral plates of the thorax 
flank the head to a considerable extent. As in 
Porcellio pictus, the dark band is in the middle of 
the back. The distal joint of the flagellum is 
nearly twice as long as the proximal, and the 
flagellum is shorter than the last joint of the 
peduncle. This species was added to the 
British list by Mr. Webb (74) in 1898. 
Porcellio vatzeburgi agrees with Porcellio 
vathket in having air-tubes in the first five 
abdominal appendages.
