1.对来自越南北部和南部、老挝北部和中部以及孟加拉国东南部的红色原鸡（原鸡）的头骨和颅后骨骼进行了骨测量比较。种群包括G. G. spadiceus、黑腹隐翅虫G. G. gallus和G. G. murghi，以揭示居群间的地理形态变异。鸡。2.利用典型判别分析法，可以清楚地将默氏亚种的形态特征与其它亚种区分开来。然而，来自越南南部的鸡种群的头骨的大小和形状与来自老挝北部的亚种spadiceus没有统计学差异。典型判别分数也清楚地表明，有来自老挝北部和越南南部的人口的头骨形态相似。3.从结果，因此，它的结论是，红色丛林鸡不表现出高水平的骨骼测量的变化之间的地理位置，至少在印度支那半岛。4.这与以前的研究，这些亚种有各种外部形态差异，并认为，动物地理障碍之间存在的北部和南部地区的印度支那半岛。
1. The skulls and postcranial skeletons of the red jungle fowl (Gallus gallus) were compared osteometrically between the populations from North and South Vietnam, North and Central Laos and Southeast Bangladesh. The populations include the three subspecies of G. g. spadiceus, G. g. gallus and G. g. murghi and were sampled to reveal the geographical morphological variations among populations in G. gallus. 2. The morphometric characteristics of subspecies murghi could be clearly distinguished from those of the other subspecies using a canonical discriminant analysis. However, the size and shape of the skull of the gallus population from South Vietnam were not statistically different from that of the subspecies spadiceus from North Laos. The canonical discriminant scores also clearly indicated that there were morphological similarities in the skulls of the populations from North Laos and South Vietnam. 3. From the results, therefore, it is concluded that red jungle fowls do not exhibit high levels of osteometric variation between geographical localities at least within the Indochinese Peninsula. 4. This contrasts with previous studies which have described these subspecies as having various external morphological differences and have argued that zoogeographical barriers exist between the north and south areas of the Indochinese Peninsula.
