 its anterior flagellum is shorter than tlie other, and the transverse 

 diameter of the globulus is never shorter, and generally much 

 longer than its stalk. The penultimate segment of the trunk with 

 five pairs of dorsal setae, two of which between the tactile setas. 

 The sternum of the anal segment has at least two jjairs, and gener- 

 ally three pairs of seta3." 



Of this genus, I have collected five species. One of these has 

 been found in very considerable numbers; of a second, I have up- 

 wards of twenty individuals; while the remaining three are repre- 

 sented only by single specimens, two of which are described. 

 The third is a form with a small anal plate bearing four short 

 subequal processes, but is, unfortunately, not in sufticiently good 

 condition to justify description. 



I have not found any members of the second genus of the 

 family, Stylopauropus Cook. 



From the fact that five species have been collected in two locali- 

 ties only, it is reasonable to suppose that a considerable number 

 will be forthcoming when these little creatures are looked for over 

 a wider range. 



Although it will certainly be necessary, at a later date, to divide 

 the genus Pauropus into several genera, I have avoided splitting 

 the genus in deference to Hansen's warning (1901, p, 341) that 

 "many species must be discovered and studied before the characters 

 of generic value can be pointed out with tolerable certainty." 



Pauropus amicus, n.sp. (Plate Ixx., figs. 1-11). 

 This species, which shares w4th Stylo pauropus pedunculatus 

 Lubbock, the distinction of being the largest known pauropod, was 

 very plentiful among fallen timber at Lindfield during June and 

 July. I found all stages, from egg to adult. It is of a somewhat 

 social habit, being almost invariably found in colonies, w^hich vary 

 from half a dozen up to upwards of a hundred individuals. I have 

 had a number in captivity, in small tubes half-filled M'ith damp soil 

 and I find, like Lubbock, that they are engaging little creatures 

 to w^atch. They spend a great deal of their time cleaning their ap-
