Patria: Küimandjaro, Kiboscho. A few specimens were taken in February 19()ü. 



Subfamilia: Onisdnae. 



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

 ural arrangement all the genera belonging to the family of Oniscidae, and I have there 

 divided the family in eight subfamilies: 1. Euhelinac, 2. Spherilloninae, 3. Rhyscotinae, 

 4-. Armadilloniscinae, 5. Scfpliaeinae, 6. Detotiime, 7. Omscinae, 8. Stenomscinac . 



Each of these subfamilies has exclusive characters taken from the mouth-parts, 

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

 to refer every genus to its natural place. 



Among the above nominated subfamilies I have treated in the main points the 

 characters of five: 



1. EuheJinae B.-L. Rev. Crust. Isop. p. 1; 



2. Spherilloninae B.-L. ibid. p. 41; 



3. Rhyscotinae B.-L. Isopoden in Voeltzkows Reise Ost-Afrika, II, p. 298. 

 -i. Armadilloniscinae B.-L. ibid. p. 302. 



6. Detoninae B.-L. Landisop. in Deutsch Südp.-Exp. IX., Zool. I, p. 84. 



Two of the three of the remaining subfamilies, 5. Scyphacinae and 8. Steno- 

 niscinac, each containing but a few known forms, I have not had occasion to make as 

 object for a deeper examination particularly because I have not had sufticient material. 



The seventh subfamily, Oniscinae, contains many more known forms than all the 

 other subfamilies together; I have 2 p. 37 divided the Oniscime in three groups: 1. 

 Armadilloidea, 2. Oniscoidea, 3. Alloniscoidea. 



The genera placed in these three groups here must be subjected to further alterations 

 as my later inquiries have shown. 



In a later paper I have a character pointed out from the mandibuke from which 

 the large genus ArmadUlo seems to retain types for different groups of genera. Further
