9. Pellorneum subochraceum Swinh. — This spotted Babbler occurred here and 

 tliere in the rich vegetation which constitutes the undergrowth in the evergreen 

 forests. I also foiind this species in the bamboo thickets but always less common 

 than in the primeval forest region. As soon as the birds scented danger they at 

 once dived down into the thick vegetation and were then quite impossible to make 

 out owing to their protective colouring. Their breeding season in Siarn seems to be- 

 gin in the first half of March for dnring this time I often saw the male chasing the 

 female, and a fine male specimen shot on the 5th of March had the genital organs 

 greatly swelled. This Babbler nearly almost keeps on the ground.

10. Alcippe phayrei Blyth. — The Burmese Babbler was a very shy and 

 cautious bird and daring the whole journey I only siicceeded in getting a male 

 specimen shot in a dense primeval forest near the Kao Plyng pass. Several authors 

 unite this species with AlciiJjie phcEocephala Jerd. but at least the Siamese speci- 

 mens are clearly distinguished in having well-marked sincipital stripes which is never 

 the case with Alcippe phceocephala Jerd.

11. Stachyrhis nigriceps Hodgs. — I only noticed the Black-throated Babbler 

 once during my stay in Siam. On the 12th of February, when making an excur- 

 sion in the forests west of Bång Hue Horn, I came to a small dry river bed, the 

 slopes of which were quite overgrown with a very thick and almost impenetrable 

 vegetation chiefly composed of tliorny bushes and grasslike plants. Here I then 

 observed a small flock of these birds moving like råts among the branches. I could 

 approach quite close to the birds without their showing any fear, but when I shot 

 a fine specimen with my small coUecting gun they at once disappeared like gliosts 

 among the tangle of branches and leaves. 



This specimen, a male, shows the following measures: Length = 130 mm., Wing 

 = 59 mm., Tail = 50 mm., Culmen = 14 mm. 



12. Mixornis rubricapillus Tick. — In the brushwood both at Den Chai and 

 Bång Hue Hom the Yellow-breasted Babbler was shot on several occasions. It was 

 very common in these localities, but I cannot remember having seen it in other
