 says that, " Pauropus huxleyi is a bustling, active, neat, and cleanly 

 creature. It has, too, a look of cheerful intelUgence, which forms 

 a great contrast to the dull stupidity of the Diplopods, or the

been found in Europe, tropical Asia, and North and South 

 America, and it is possible that they have a very wide distribution. 

 There are three families. Drawings of Pauropus and Enryp)auropus, 

 to illustrate the morphology of the Pauropoda, are placed in 

 Table-case 27.
