 Similar to the last; larger; bill 12.00 to nearly 15.00; wing 20.00-23.00. In full breeding

little shorter (?) than middle toe and claw. Head, neck, tail, and entii-e under parts pure 

 white; mantle pale pearl-blue, lighter than in glaucescens, about as in leucopterus and kumlieni.

 The main point of distinction is size, nelsoni being con.siderably larger." Wing 17.25; tail 

 8.90; culmen 2.20; bill along gape 3.00, depth 0.80, tarsus 3.00; middle toe and claw 2.90.
