Dr. Abbott also took a nest and two eggs with parent bird near base 

 of Kao Nona Plu, March 9, 1897. 



The series collected by Dr. Abbott in Trang are browner, less gray 

 on the chest than specimens from eastern and southeastern Siam and 

 French Indo-China. The latter may belong to a different form. The 

 specimens from Tenasserun appear to be somewhat intermediate. 



This form is apparently common all over Peninsular, southern, 

 eastern, and southeastern Siam. It occurs also on many of the islands 

 off the coast. It ranges from the Malay States north through Penin- 

 sular Siam to central, eastern, and southeastern Siam, and east to 

 southern Indo-China. 



Kobinson and Ivloss ^* have recorded it from Trang, Pulo Terutau, 

 and Pulo Langkawi; Robinson ^^ from Koh Samui and Koh Pennan; 

 Gyldenstolpe ^^ from Bang Hue Hom, northern Siam; Robinson and 

 Kloss " from Lat Bua Kao, Satahip, and Koh Mesan. Deignan '* 

 states that it is not common in northern Siam and confined to districts 

 watered by streams flowing into the Mekong. It has been recorded 

 from many additional localities, but the above are sufficient to indicate 

 its range. Count Gyldenstolpe's record from Bang Hue Hom is the 

 only northern one I have seen, however. 



PYCNONOTUS CYANIVENTRIS CYANIVENTEIS Blyth 



Pycnonotus cyaniventris Blyth, Journ. Asiat. Soc. Bengal, vol. 11, p. 792, 1S42 

 (Singapore) . 



Dr. W. L. Abbott took a male at Lay Song Hong, Trang, August 21, 

 1896. He gives the bill as black and the feet dark leaden. 



Robinson and Kloss ^° record it from Tasan, Chumporn, and say 

 that they took specimens in Trang in October 1909, but they failed to 

 record them in their paper in The Ibis, 1911; they have also recorded 

 it from Kao Keo and Kao Ram, 1,200 feet, Nakon Sritamarat.^° 



The form occurs from southern Tenasserim south through Penin- 

 sular Siam to Singapore and Sumatra. 



The species is a small one, easily recognized by its slaty-blue head 

 and underparts; pyrite-yellow back and wings; empire-yellow under 

 tail coverts. Wing, about 75; culmen, 12 mm. 



This form seems to be more abundant at the southern end of the 

 Malay Peninsula, though Robmson *' says it is common throughout 

 the Peninsula from sea level to 3,500 feet, but all the locaUties ho 

 mentions are south of Siamese territory. 



A somewhat smaller, brighter form is found in Borneo.
