After Latham had worked through the “ Watling ” drawings and described 
so many Australian birds in the Second Supplement to the General Synopsis 
of Birds he included a number of “ Additions ” on pp. 368-376. In connection 
with the first species he wrote : “ Inhabits China ; for this, and many of 
the following, I am indebted to General Davies.'^'' Nearly all those additions 
were Australian species, and, moreover, a number were from Norfolk 
Island, though this locality is erroneously given in connection with some 
of the species. 
However, on p. 371 is described the “Pacific R(oUer). Length nine 
inches ; bill and legs red ; head and neck chesnut ; chin and throat, down 
the middle, black, bounded on each side with a line of white ; the lower part 
of the neck from the chesnut changes to green, and from thence all beneath 
is paler green ; wings fine blue ; base of the quills white, forming a spot of 
white when expanded ; rump and tail-coverts green ; tail itself, and ends of 
the quills dusky blue-black. Inhabits Port Jackson.^ ^
