Ehipidura cockerelli cockerelli (Rams.). 



Sauloprocta cockerelli Ramsay, Proc. Linn. Soc. N. S. Wales, 

 iv. p. 81 (1879 — " Gaudalcanar," i. e. Guadalcanar). 



Upperside slate-black. Nearly the entire outer webs o£ 

 the inner secondaries and tips of their inner webs white. 

 All rectrices uniform slate-black. Breast with large drop- 

 like longitudinal white spots. Culmen from base 19-20, 

 wing 86-91 mm. 



Hab. Guadalcanar (5 skins examined). 



Ehipidura cockerelli septentrionalis, subsp. nov. 



Coloration as in Rh. c. cockerelli, but culmen only 16"6 

 to 18 (once 19 mm.), wing 82 to 87 mm. Both in this and 

 the former, as well as in the other subspecies, the males are 

 larger than the females, though the sex-marks on the labels 

 do not bear this out in all cases. There is thus, in our 

 opinion, no overlapping of measurements. 



Type: ? ad. No. 3537, A. S. Meek Coll., shot ll.xii. 1907. 



Hab. Bougainville, the northernmost island of the 

 Solomon group (6 skins examined). 



Ehipidura cockerelli interposita, subsp. nov. 



Dijffers from Rh. c. cockerelli and septentrionalis in the 

 greater extent of the white colour on the inner secondaries, 

 which have the outer webs entirely, the inner largely (about 

 half their length) white. Wings 84-90, culmen 17-18 mm.
