Fani. Campepliagidae. 



47. Pericrocotus fraterculus Swinh. — The Burmese Scarlet Minivet is only 

 represented in the collection by two specimens: a fine male obtained near Pak Pan 

 on the 18th of February and a female shot at Sakerat on the 5th of January. I 

 never observed this species any more so that it seems to be very rare in Siam, The 

 plumage of the female is very much worn and there is only one tail-feather left. 

 The male, however, is in full plumage and shows the following measurements : 



Length = 190 mm., Wing = 85 mm., Tail =85 mm., Culmen = 12 mm. 



Hartert and several other authors such as E, W. Oates and E. C. Stuart 

 Baker have written much about this species and its allies. Hartert says (Nov. 

 Zool., Vol. IX, 1902, p. 555) after having examined a large series from Northern 

 India, Cachar, Assam, Burma, Tenasserim, some from Hainan, China and the Malay 

 Peninsula that they are to be counted into three groups: the largest form from 

 N. W. India and the Himalayas, a smaller form from Hainan and a still smaller from 

 the mountains of the Malay Peninsula. The first, Pericrocotus speciosus Lath. has 

 the wings in adult males from 102—117 and a tail from 101 — 115 mm. The Hainan 

 birds are smaller: wing 96—98, tail 95—100 mm. The smallest are the birds from 

 the mountains of the Malay Peninsula with a wing measuring only 88 — 90 and tails 

 about 80 mm. 



When comparing the Siamese birds with the above given measurements it vvill 

 be seen that the Siamese form seems to be nearest the form from the Malay 

 Peninsula but even still smaller as concerns the wing measurements. 



48. Pericrocotus solaris Blyth. — Of this species I can only record a single 

 female shot from a small flock near the village of Non Luum on the Korat plateau. 

 It seems to be very rare in Siam as I never observed it at any other place either 

 in Central or Northern Siam. 



Length = 180 mm. Wing = 88 mm. 



Tail = 91 » Culmen = 12 » 



49. Pericrocotus peregrinus L. — During my journey I only obtained a male 

 specimen, shot in a bamboo forest near Non Luum in Eastern Siam, and I cannot 

 give any more records of the occurrence of this bird in Siam because I did not get 

 any more certain observations. 



Length =150 mm., Wing = 64 mm., Tail = 78 mm. 



50. Campophaga neglecta Hume. — In the brushwood jungles near Bång Hue 

 Hom I on the 13th of February cauglit sight of some specimens of the small Cuckoo 

 Shrike and I at last succeeded in getting a female. The family of Campephagidse 

 is characterized by the spinous shafts of the rump-feathers whicli may easely be felt 

 in some species. But in my specimen of Campophaga neglecta they are rather dif-
