Patria: Küimamljdro, Kiboscho. A few specimens were taken in February I90ü. 



Subfamilia: Oniscinae. 



In "A Revision of Crust. Isop. Terr." p. 36 I have atlempted to set up in a nat- 

 ural arrangement all the genera belonging to the family of Oniscidar, and 1 have there 

 divided the family in eight subfamilies: 1. Euhelnute, 2. Spherillonlmie, 3. RhysvotiniK. 

 i. Armadüluniscinae, 5. Scyphacinae, (i. Detomna', 7. Oniscinae, 8. Stenomscinae. 



Each of Ihese subfamilies has exclusive characlers taken from the mouth-parts, 

 and owing to them, it had been possible everywhere, so far as my studies have gone, 

 lo refer every genus to its natural place. 



Among the above nominated subfamilies 1 have Ireated in Ihe main poiiits Ihe 

 characters of five: 



1. KnlicUiKW B.-L. Rt'v. Crust. Isop. p. 1; 



2. Spherilloninae B.-L. iiiid. p. \{\ 



3. Rlijisrofimte B.-L. Isopoden in Voeltzkows Reise Ost-Afrika, 11, p. 298. 

 'y. ArtHadilloniscinffe B.-L. ibid. p. 302. 



(i. Detoiiinar B.-L. Landisop. in Deutsch Südp.-Exp. IX., Zool. L p. 84. 



Two of the three of the remaiiiing subfamilies, 5. Scuphadnae and 8. Sfeiiv- 

 niseinae, each containing but a few known forms, I have nol had occasion lo make as 

 object for a dceper examination particulaiiv because I have not had sufiicient rnalerial. 



The seventh subfaniilv, Oii/sriiiar. conlains many more known forms (hau all the 

 otlier subfamilies together, 1 liave 2 p. 37 divided Ihe Onisdiui in Ihree groups: 1. 

 Armadilloidea. 2. Oniscoidca. 3. ÄlloHiscoidra. 



Tiie genera placeii in Ihese three groups here inust be subjected lo fuither alleralions 

 as my laier iii(|uiries have showu. 



In a later paper I iiave a character pointed out from Ihe mandibuhe from wliich 

 llie iarge genus Armuddln seems lo relaiii lypes for differeiit groups of genera. Fnilher
