6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 134 
Accordingly, Mergui, still farther north and the provenience of a 
number of Helfer’s skins, may be considered a suitable terra typica. 
Criniger ochraceus ochraceus seems to be sympatric in central 
Tenasserim with Cringer pallidus robinsoni and Criniger flaveolus 
burmanicus, and in southwestern Thailand with Criniger flaveolus 
burmanicus.

of Birds, vol. 3, 1901, p. 316. New name for Criniger Cabamsi A. Miller, 
Journ. fiir Orn., Jahrg. 30, No. 160, November 1882, p. 384 (Phuket, Phuket 
Province, Thailand), not Criniger cabanisi Bowdler Sharpe, “1881” [1882]. 
Range.—The Mergui Archipelago (Ross, Sullivan, and St. Mat- 
thew’s Islands) and mainland Tenasserim from the head of Pak Chan 
Estuary to Victoria Point; Thailand from Sathani Map Ammarit 
(lat. 10°50’ N., long. 99°20’ E.) south through the Malay Peninsula 
into northwestern Malaya (Perlis State and the Langkawi Islands). 
Remarks.—Criniger ochraceus sordidus has lain in synonymy with 
the nominate race for many years, but it is readily distinguished in 
series by its darker upper parts and more ochraceus, less buffy, under 
parts. Most discussion of this form has been based upon skins from 
the Merguis and Tenasserim and from the Siamese side of the Isthmus 
of Kra, all of which are, strictly speaking, sordidus>ochraceus, and 
therefore misleading for taxonomic purposes. 
This form is apparently sympatric in southernmost Tenasserim, 
peninsular Thailand, and northwestern Malaya with Criniger bres 
tephrogenys. 
Criniger ochraceus sacculatus Ropinson. 
Criniger ochraceus sacculatus RoBINson, in Robinson and Boden Kloss, Ibis, 
ser. 10, vol. 3, No. 4, October 8, 1915, p. 746 (Ginting Bidei [lat. 3°18’ N., 
long. 101°50’ E.], Selangor State, Malaya). 
Range.—Malaya, from northern Perak south to Negri Sembilan 
and Pahang. 
Remarks—Criniger ochraceus sacculatus is apparently sympatric 
in Malaya with Criniger bres tephrogenys. It is frequently stated 
that the former is a hill form, while the latter is one of the lowlands,
