species present but subspecific identity uncertain.

(1985), Stuart et al. (1987) as well as results from
our recent research Jensen & Bregger-Jensen,
1992) and new inormaion on the Iringa Ground-
robin received from N. E. Baker and E. M. Boswell

.
In Table 10.7 we present an analysis of the
subspeciaion pattens shown in Table 10.6.
Ignoring the isolated Uluguru Mountains, Table
10.7 shows the frequency of subspecific distribu-
ion boundaries between the various forest blocks.
We treat the Ngurus and Ukagurus as one block
because they are geographically close together,
and many species are absent from the dry Uka-
gurus. As can be seen, most of the subspecific
breaks occur in four locaions:
occurring in the East Coast Escarpment. The
remaining 38 species all occur through the East
Coast Escarpment as only one race. Table 10.6 is
arranged with the forests in geographical
sequence rom the Usambaras (north) to the
Nyika Plateau (south); however, the Ulugurus,
which form an isolated block to the east of the
main East Coast Escarpment with several
endemic subspecies, are placed on the far right of
the table. This enables the reader to obtain an
easier impression of characterisic subspecific dis-
ribuions along the mountain chain. For the rec-
ogniion of subspecies we have generally followed
Benson & Benson (1977) and Britton (1980), with
subsequent revisions from Jensen & Stuart
(1982), Franzmann (1983), Jensen, Bregger-
Jensen & Petersen (1985), Stuart & Jensen
