■ 1 ?. Aden. 



Mr. Boulenger, in 1887, pointed out' that H. Jiaviviridis^ 

 Eiippell, is identical with H. coctcei, D. & B. "While in Frankfurt- 

 on-the-Main, two years ago,- I examined the type o£ H. Jiavi- 

 viridis, Eiippell, and arrived at the same conclusion, being unaware 

 at the time, however, of Mr. Boiilenger's identification of the 

 two. 



As Dumeril and Bibron quote Eiippell's ' Xeue AVirbelthiere ' 

 in their third volume, it is evident that H. Jiaviviridis must stand 

 for this widely distributed Gecko, which was first described from a 

 Massowah specimen. 



Of late years, it has been found at Korseir" and at Aden\ 

 Specimens exist in the British Museum from the latter locality and 

 also from Muscat ^. 



" This is the common house Gecko of Aden, Shaikh Othman, and 

 Lahej, and is plentiful in these localities."

This is the first notice of the occurrence of this species at Aden, 

 but, so long ago as 1851, it was recorded by A. Dumeril from the 

 rocks at Muscat \ These Aden specimens agree exactly with 

 examples in the British Museum from Mount Sinai, whence the 

 species was original^ described. 



" Plentiful in the bed ol' the stream at Haithalhim, The bed 

 was dry and consisted of pebbles of various sizes and sand, with 

 small bushes here and there, chiefly Dipterygium glaucumJ*

Mr. Boulenger " has recorded this species from Muscat, but this 

 is the first notice of its occurrence at Aden. 



" It seems to be rare, as I met with it only on three occasions.
