Hartlaub (Abh. Nat. Ver. Bremen, Vol. 14. 1898 p. 349) lias described a species 

 of Garrulax which inhabits Hainan under the name of G. schmackeri. This form is stated 

 to be very similar to G. moniliger Hodgs. though it differsfrom that species by having 

 the tail-feathers tipped with buff instead of whitc; the outer vvebs of the outer primaries 

 are olive brown instead of hoary grey. The buff colour of the foreneck is less brighl and 

 the rufous on the napc is also generally darker. 



Grant (P. Z. S. 1900 p. 475) records it as being smaller than typical G. moniliger 

 and gives the wing for G. schmackeri to 4,2 — 4,3 inches while the wing in G. moniliger 

 measures 4,8 — 5,o inches. 



Two of the specimens collected at Pak Koh during April 1914 have the tail-feathers 

 tipped with buff. But these specimens are nol smaller than typical moniliger obtained 

 at the same localitiy (their wings measure 126 and 125 mm. respectively). Two other 

 specimens, one from this same locality and the other one from Koon Tan further north 

 have their tail-feathers tipped with almost pure white. The Koon Tan specimen also 

 has the rufous collar on the hind-neck decidedly paler than the other birds. 



It therefore seems to me that the »species » described as G. schmackeri is only based 

 on birds in fresh plumage and that it is nothing else than typical G. moniliger. Unfortun- 

 ately I have no Hainan specimens to compare with and am therefore unable to asccrtain 

 if the Hainan form is separable or not. 



A nest containing 3 påle blue eggs was found near Pak Koh on the 16th of April

The Black-throated Laughing-Thrush was very rare in the parts of Siarn visited 

 during my journey. It was only observed at two different occasions: once in company 

 with some of the other kind of Laughing Thrushes in a dense valley among the Koon 

 Tan mountains; the second time two specimens were seen in an orchard just outside the 

 town of Chieng Hai in Upper Siarn. 



The specimen from Koon Tan is quite typical.

This fine species has only, as far as I know, been recorded from the Mooleyit moun- 

 tain in Tenasserim, where both Tickell and Davison met with it from 3 000 feet to the 

 summit. My specimens which were obtained in a very dense and thickly wooded valley
