Patria: Several specimens of this species were foune in the caves at iMkulumusi 

 [)r. Tanga, in the montli nf June 1906. Also the expedition of Mr. Ali.ii.vud found 

 specimens of lliis species in the sanie locality, Nov. 1903. 



A series of Terre.strial Isopods has in the course of time been collected from 

 Central-Africa, that in consequence of their exterior habilus, e.^pecially on account of 

 tlieir ability of conglobation, have a great similarity to the species of the genus Anna- 

 dillo. They are easely separated, however, by the form of the telsum which varies to 

 a great extent froni the straight sided triangulär form to an elongate acuminate triang- 

 ulate or rightangular |)rol()ngation, but are never conslricted in Ihc middle in Ihe form 

 of an hour-glass as in Ihe case with AriHadillo. 



Gerst.kckeh founded the genus Pen'sri/phis upon one of these central african species, 

 and a i^econd species was taken by Dollkus as type for the genus Sijnannadillo. In 

 the course of time wlien I received new species I referred them either to one or the 

 ollier of lliese genera, and t(» wliith I have atided below a third genus Mi<-ro(( rcus. 



II has ofleii been very diflicult for me to hnd the correct position for new species, 

 but have upon my more recent researclies been able to make more diiinite divisions, 

 and similarly as in Ihe genus Pcnsri/pliis \ give below a complele descriplion to Ihe 

 Iwo other genera.

I kiiow altogether 14 species which 1 refer to this genus, which are found distrib- 

 uled over the hole N. Iv Africa, from Egypt to Abessinia, Djibouti, Somali, British- and 

 (ierrnan EasL-.Vhika. Eiglil species are described: P. in'ridl/s Gf.rst., P. convrxus B.-L..
