tendency to be broken into spots, and tbe bands along the sides of the tail are faint or 
wanting. Otherwise there appears to be no constant difference. 
The colonration is that of the form to which Dr. Strauch has given the name of 
and which is mainly distinguished from the typical Z. ravergieri by the 
tail being spotted instead of striped. Dr. Strauch adds that, as a rule, in Z. fedtschenkoi 
the number of longitudinal rows of scales is twenty-three, twenty-one being the exception, 
whilst the reverse is found in Z. ravergieri. He also calls attention to a slight difference 
in the form of the head, which is rather broader and less depressed in the first-named form. 
Z. fedtschenhoi is said to be common in Eussian Turkestan. 
In the three specimens from Eastern Tm’kestan, the rows of scales round the body are 
twenty-one in number, and the head is of the same form as in typical Z. ravergieri. I have 
already ^ shown that the two forms pass into each other in Persia, and the specimens from 
Eastern Turkestan tend to the same conclusion. 
In both the specimens from Yangihissar, there are three postoculars on each side, but only 
two, as usual, in the Yarkand example. In the latter there are 222 ventrals and ninety-one 
pairs of subcaudals. 
20. Tropidonotus htdrtjs. 
1, Kashghar; 2.15, Yangihissar, Eastern Turkestan. 
This snake is apparently as common in Eastern Turkestan as it is, according to Strauch,^ 
farther to the westward. The specimen from Kashghar was procured on the 2nd Eebruary, and 
is noted on the label as having been found frozen in a field; the Yangihissar specimens were 
collected in April. 
The majority of the snakes of this species obtained in Eastern Tm’kestan appear to have 
five postoculars. They are oHvaceous above, with the back spots rather indistinct as a rule, 
and a great portion of the ventral shields is black. 
21. Tropidonotus plattceps. 
1, Mari; 2, 3, Kashm ir. 
I can see no difference between these specimens and those from other parts of the 
Himalayas. This species, which had previously been obtained by Dr. Jerdon in Kashmir,® 
appears to be one of the Himalayan forms, like Qom^sosoma hodgsoni^ which range farther 
to the north-west than do most of the species characteristic of the Himalayan region.
