Although I kept a sharp look out for a specimen during my recent visit to Aden, I failed to obtain one, but I saw one in the possession of two Frenchmen who visited Lahej when I was there. It may be the young of C. calcarifer or possibly another species, but I am disposed to think that it is the former." OPHIDIA. 17. ZAMENIS RHODORHACHIS, Janl.

The highest number occurs in Egypt and in Midian, and in the former country no specimen has yet been found with a lower number of ventrals than 248. In Eastern and South-eastern Arabia, Muscat to Aden, the ventrals range from 220 to 239, while, on the other hand, from Bushire to Baluchistan (Kalagan) these numbers fall very low, the range being from 214 to 218. In the Bugti hills, on the right bank of the Indus, to the north of Jacobabad, and in North-western India, ' I am indebted to the Trustees of the Indian Museum for the opportunity of re-examining the types of Z. ladacensis. They are unquestionally identical with Jan's Z. rhodorhachis. At the time I described the species, Jan's work was not in the Library of the Indian Museum, Calcutta. a B. C. signifies " broadly in contact" ; C. " contact" ; and N. C. " not in contact." |
