Neumaim^s six bircls^ which are uow in the Triug Museum^ 

 have wings, as Kloss states, between 112 and 118 mm. 

 From this it is evident that we cannot separate prater- 

 missa on account of size alone, especially when it appears 

 that saigonensis is named from an abnormally small-sized 

 bird. 



There is, all the same, one quite good difference between 

 the south Chinese birds and those from Cochin China, 

 Annam, etc., and that is, so far as we know now, all true 

 faiostricta have a red patch or spot on either side of 

 the lower throat, whilst those from south China have 

 none. 



The two forms will therefore stand as follows : — 



(1) Theveiceryx faiostricta faiostricta. 



Bucco faiostricta Temm. PI. Col. iii. 1831, pi. 527 : 

 Cochin China. 



Cyanops p/tceustricta saigonensis Neumann, Bull. B. O. C. 

 xxiii. 1909, p. 31. 



Neumann's type is No. 88.11.25.278, Tweeddale Collec- 

 tion, British Museum ; no sex, locality Cochin China [vide 

 Bull. B. O. C. xxiii. p. 31). The wing is 102 mm. 



Bather smaller : wing 108-115 mm. (one 102 mm.) ; a 

 red spot well developed on either side of the lower throat. 



Habitat. Cochin China, Annam, and Siam. 



(2) Thereiceryx faiostricta prsetermissa. 



Thereiceryx Jlaxost rictus pratei'missus Kloss, Ibis, 1918, 

 p. 101 : Nanchan Island, Kwangtuug, South China. Now 

 in Triug Museum. 



A larger bird ; wing 112-118 mm. ; no red spot on either 

 side of the throat. 



Habitat. As above, so far as is now known. 



It may eventually prove that the south-eastern Cochin 

 China form is always very small, in which case we 

 should have three subspecies and Neumann's name would 

 stand.
