12. HiEROCOCCYX FUGAX. 



Cuculusfugax, Horsf. t.c. p. 178, "Java" (1820). 

 Sumatran, Bornean, and Malaccan examples offer no points 

 of difference. 



13. Centropus eurycercus. 



Cuculus bubulus, Horsf. apud Raffles, t. c. p. 286^ " Su- 

 matra." 



Centropus eurycercus, A. Hay; Blj-th, J. A. S. B. 1845, 

 p. 551, "Malacca." 



Sumatran and Bornean individuals agree with typical spe- 

 cimens. As yet I have not been able to compare them with 

 the Javan form, which is, according to Blyth (/. c), a smaller 

 species, 



14. Thriponax javensis. 



Picusjavensis, Horsf. t.c. p. 172, "Java" (1820). 

 The examples obtained by Mr. Buxton in no respect differ 

 from Malaccan, with which the type is said to agree. 



15. Ttga rafflesi. 



Picus raffiesii, Vigors, App. Mem. Raffles, p. 669, " Su- 

 matra" (1830). 



Bornean and Malaccan individuals are inseparable.

Picus tiga, Horsf. t. c. p. 177 "Java" (1820). 



" Tiga rvfa," Raffles, /. c. p. 290, " Sumatra" (1821). 



Sumatran, Malaccan, and Javan individuals do not speci- 

 fically differ. Of somewhat smaller dimensions than the race 

 which inhabits the Burmese countries. 



17. Callolophus mentalis. 



Picus mentalis, Temm. PL Col. 384, "Java" (1826). 

 Sumatran and Malaccan examples do not vary.
