the mother in the genus Edoliisoma are impressed upon the male young at an 

 earlier stage than the acquisitions of the father. In Edoliisoma the paternal char- 

 acters are first displayed when the young male assumes its second plvimage. 

 Sharpe says that the young male of E. nigrum "gradually gains the adult male 

 plumage by the double action of a direct moult and by a change of feather" 

 (Cat. B. IV, 46). What the very earliest stages of plumage of these Cuckoo- 

 shrikes will teach us, we cannot yet know, probably not much. 



In the stomach of a specimen of this bird the Drs. Sarasins found crickets. 

 E. morio of Celebes is a very distinct species. It is apparently most nearly related 

 to E. talaiitensis of Talaut and E. salvadorii of Sangi, also to Dr. Sharp e's 

 newly described E. everetti of Sooloo, the male of which is said scarcely to 

 differ from the male of E. morio, but the female has the entire belly cinereous 

 (9), and to E. emancipata Hart, of Djampea. The male of E. meyeri of Mysore 

 is also much like the male of E. morio, but the female is qu^ite different, being 

 uniform fulvous rufescent below or with a few spots, not regularly barred like 

 the female of E. morio. Altogether much similarity is found amongst the males 

 of Edoliisoma. This may be accounted for on the supposition that the males 

 have retained the plumage of a formerly wide-spread species from which the 

 females have deviated in various directions. Edoliisoma is a link of questionable 

 value between Celebes and the Australian Region. Its occurrence in the Philip- 

 pine Islands, Sooloo Islands, and Uap in the Carolines are suggestive of an 

 exodus from the east to these islands by flight, of which these birds appear to 

 be very capable.

Descriptions. Sharpe 1, 2. 



Adult male (type of the species). Like the adult male of E. mcyrio (supra), but the general 

 colour duller (slightly smoky) jjlumbeous slate-gi-ey; chin, throat and chest uniform 

 with the under surface, not black ; lores and feathers in front of eye black ; ear-coverts 

 and below the eye blackish (Tabukan, Great Sangi: Meyer — Nr. 13580). Size rather 

 larger than E. morio. 



Female. Different from the female of E. m,orio: under surface huffy white, broadly barred 

 (except on under tail-coverts) with brownish black, instead of deep cinnamon rather 

 narrowly barred; middle tail-feathers blackish at the tip only — not the terminal 

 fourth black as in E. morio (Great Sangi, [Q], 13''' of March 1893: Nat. CoU. — 

 C 12691). 



Immature? Two other specimens which are moulting do not lUffer fi-om the female, except 

 that brown bases to the feathers of the upper surface are apparent, and in one
