There are granulations on the middle of the segments in 

 Porcellio ratzeburgii 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 ratzeburgii agrees with Porcellio 

 rathkei in having air- tubes in the first five 

 abdominal appendages.
