 is 1.3 in P. dunbari and 1.5 in P. stebbingi) and in the relative length of 

 pereonite I to pereonite VII. In P. stebbingi, the ratio is 1.15 ± 0.05 in 

 males and 1.25 ± 0.08 in females; in P. dunbari it is 1.01 ± 0.03 and 

 1.11 ± 0.03 respectively. The statistical significance of these measures
