It is disheartening to find that, in a modern paper on Siamese 

 birds, there should be very considerable disregard of much previous 

 literature on the subject, a good deal of it quite recent, with the 

 result that alien races are imported into the fauna. The case of 

 Criniger pallida pallida is one in point. 



The bulbul now under discussion was, prior to 1902, known 

 as G. gutturalis Bj)., founded on Bornean birds, though Hume and 

 Davison in 1878 correctly referred Tenasserim birds to C. ochraceus 

 Moore, collected by Heifer in Central or South Tenasserim in about 

 1840. 



In 1900 Richmond described the bird from Trang as Criniger 

 sordidus, comparing it with G. gittturalls auct., probably G. tephro- 

 genys Jard. and Selby. 



In 1902 Hartert (Nov. Zool. ix, 1902, p. 558), in the course 

 of an article on a collection of birds from Pahang, cleared up the 

 confusion and showed that there are two species in the Malay 

 Peninsula and Burma, viz., G. ochraceus Moore, from Tenasserim and 

 G. tep>hrogen i/s Jard, and Selby (type fixed as Malacca). 



In 1911 (Ibis, p. 57) we recorded further as C. sordidus 

 specimens from Trang and Langkawi which had been compared with 

 one of the paratypes, and stated that the distinctions between it and 

 G. ochraceus were extremely fine.
