Coin-marked snakes, February 2016

Labelled as Psammophis spp. - I can check which if anyone\'s curious.
Photo taken on the 17th February 2016.

I'm curious - having taken care for 2 species myself at a privat collection about 30 years ago.

Having looked through my copy of 'A guide to the reptiles and amphibians of Egypt' (A brilliant guide by S. Baha El Din), I think these are coin-marked snakes, Hemorrhois nummifer - unless someone has a better ID?

Thank you devilfish !
