Edolisoma mindanense sula, subsp. nov. 
¢ ad. Differs from that of EL. mindanense mindanense at a 
glance by being much darker on the rump and upper tail- 
coverts, and larger, especially the bill. Differs from that of 
E. obiense by having a smaller bill.— ? ad. Like the male, 
but throat and ear-coverts not black or blackish, but uniform 
bluish grey like the abdomen; under wing-coverts not slate- 
grey, but white, more or less speckled with grey. The 
female is thus quite unlike the rufous females of H. obiense. 
Hab. Sula Besi and Sula Mangoli Islands, east of Celebes. 
Type. 2 ad. Sula Besi, October 1897. W. Doherty coll. 
(Tring Museum). 
We have, in the Tring Museum, two adult males, two adult 
females, two juvenile males, and one juvenile female, all from 
the islands of Sula Mangoli and Sula Besi, collected by the 
late William Doherty. | 
Edolisoma morio pererratum, subsp. nov. 
In Noy. Zool. 1908, p. 27, I have at length discussed our 
specimens from the Tukang-Besi Islands, Tomia and Kali- 
dupa, and I left it undecided whether these birds belonged to 
E. obiense, because we bad no adult females. But I am now 
convinced that the specimen no. 4408 (cf. /. c.), though said 
to be a male, is an adult female, or practically adult, showing 
only traces of immaturity. Therefore this form has nothing 
to do with FH. obiense, as the female is not rufous with 
a bluish-grey cap, but the upperside is brownish grey, more 
bluish on the crown of the head, underside white, with a buff 
wash on the abdomen, and closely barred with brownish 
black, under tail-coverts rusty-buff with a few small black 
markings. This female is very much like that of Z. morio 
emancipatum, but the upperside is not so clear grey (unless 
this is a sign of immaturity), and the underside has broader 
bars, especially on the throat. It differs at a glance from 
the female of E. morio morio by being smaller, by the 
lighter and less bluish upperside and the whitish, instead of 
rufous, underside. The adult males do not differ from those 
of obiense, except that the edges to the wing-quills are a little
