The genus Zephronia contains Millipedes from Ceylon, Borneo, 

 Natal, Madagascar, and other Asiatic and African places, beside 

 which our little "Pill-beetle" [Glomeris marginata) is a tiny 

 dwarf. Mr. Arthur Adams, F.L.S., the Naturalist of H.M.S. 

 ' Samarang/ mentions that, in the moist woods of Borneo, he. 

 Sir Edward Belcher, and Bajah Brooke found "great treasure" 

 of them among decaying vegetable matter. He found at the 

 same time some parasitic plants (perhaps of the liajfflesia group), 

 which he could not preserve, but which were vividly present to 

 his memory, as he described them. Some of the Zephronice he 

 brought, though in bad condition, were very distinct. I pur- 

 pose here to describe two or three species, now in the Museum 

 Collection. 



The genus Zephronia is a very well-marked one, first recorded 

 by Dr. Gray in Griffith's edition of Cuvier's ' Animal Kingdom.^ 

 Exclusive of the head, the body consists of twelve segments, and 

 a plate, which may or may not be taken as a thirteenth seg- 

 ment, though I am inclined to regard it as belonging rather to 

 the head than to the body. Professor Brandt has divided the 

 group into two genera, to which he has given the names of 

 Spharotherium and Sphteropaius^. lie places them in his Sec- 

 tion b. of the division Pentazonia; the section is characterized 

 by the numerous eyes being arranged in two groups, one on each 

 side of the head, by the antennae being inserted on the sides of 

 the head, and by the number of segments, to which I have 

 already alluded. His genus Sphcerotherium contains species
