We are now acquainted with four species of Zamenis from 

 Somaliland ; they are easily distinguished by the numbers of 

 scales and shields : 



1. Z. somalicus, Blgr. Sc. 15, V. 



2. Z. brevis, Blgr. » 19, » 



3. Z. rhodorhachis, Jan. » 19, » 



4. Z. smithii, Blgr. » 21-23, » 

 Z. somalicus and Z. brevis are as yet only known from single 



specimens obtained in Somaliland; Z. smithii inhabits also Galla- 

 land and extends northwards to Assab ; whilst Z. rhodorhachis 

 has a wide range, being found from Upper Egypt to Somaliland, 

 and from Transcaspia, Syria, and Arabia to North Western India.
