The immature male taken September 1 resembles the adult fe- 

 male very closely. The top of the head and throat are a little darker 

 and the metallic rictal streak is making its appearance. 



As specimens of the species seem to be rather scarce in collections 

 the measurements of the series is appended : 



180. CYRTOSTOMUS FRENATUS MEYERI, Hartert.^" 



A fine series of adults of both sexes and immature from : Kapas 

 Bay, July 22 and November 18-23, 1914 ; Soemalata, September 3-7, 

 1914; Kwandang, September 15, 1914; Toli Toli, November 29-De- 

 cember 19, 1914; Kampa, February 14, 1915; Tandjong Penjoe,. 

 February 17-26, 1915; Likoepang, January 16 and 21-March 3 and 

 4, 1916; Ayermadidi, April 2, 1916; Koeala Prang, June 18, 1916; 

 Manembo Nembo, June 22-24, 1916. 



This series differs from typical C. /. frenatus in being darker and 

 more greenish above, with larger bills. 



181. CYRTOSTOMUS FRENATUS PLATENI (W. Blasius). 



A good series of both sexes from: Parigi, September 19 and 28,. 

 1916; Toboli, October 18-22, 1916; Manilili, December 16, 1916; 

 Gimpoe, August 2-27, 1917 ; Koelawi, January 30-February 14, 1917 ; 

 Toewo Mountain, Besoa, October 28 and November 2, 1917. 



Specimens from Gimpoe, Koelawi, and Besoa seem to be a little 

 lighter yellow on the breast, the backs duskier, and slightly smaller 

 than specimens from the north {C. f. meyeri). The difficulty comes 

 in assigning specimens from Parigi, Toboli, and Manilili, as they 

 are intermediate, but they seem to be nearer the southern form and 

 I have placed them here for the present. It is uncertain whether 

 the central mountain race belongs to the southern form or to 

 Cyrtostorrvus frenatus dissentiens of Bonthain Peak, adults of which 

 are not available for comparison, but until more is known of th&
