1861.] VERTEBRATES OF NEPAL. 217 



The specimen figured by Mr. Hodgson is uniform brown above 

 and whitish below. In the specimen which is figured in the ' Pro- 

 ceedings of the Zoological Society,' some obscure blackish cross 

 bands made their appearance on the anterior part of the side of the 

 trunk when the skin commenced to dry. These bands being 

 very distinct, I considered it possible for some time that A. owenii 

 is the young of A. rappii. Mr. Hodgson, however, figures a speci- 

 men with a very distinct black collar (as in A. owenii), which is 

 21 inches long, and evidently adult; so that both species appear to 

 be really distinct. Both are called " Sirdaghia " in Nepal ; and I see 

 from a note of Mr. Hodgson, that having received a small specimen 

 of the uniform species {A. rappii) and a large one of the collared (A. 

 owenii), he considered the former as the young state of the latter.

Mr. Hodgson figures a variety of this species : the body is uniform 

 brown, without any cross bands ; abdomen whitish ; neck with a black 

 collar edged with white posteriorly ; crown of the head with two 

 angular blackish cross bands, the convexity of the bands pointing 

 forwards.

The Matia. 



This species appears to be a truly Himalayan form, all the spe- 

 cimens known coming from those mountainous regions. The British 

 Museum possesses three from Sikkim, two from Khasia, and one 

 from Nepal, through Mr. Hodgson. A coloured drawing.
