[OSRS-PROJ] Another unknown projection

Sorry to do this again - I'm working on a project to create global maps 
of bird ranges and none of the sources record the projection of 
distribution maps. This one is a map of Europe 
(http://www.bio.ic.ac.uk/research/iowens/orme/BWP.jpeg  - 600kb file).

The parallels are parallel straight lines and the meridians are 
smoothly converging curves - this all says pseudo-cylindrical to me. 
The spacing of the parallels increase markedly toward the pole, which I 
can't immediately associate with any pseudo-cylindrical projection.

It could be that the parallels _are_ curved but just not visibly so in 
the image, but given the size of the area mapped this seems a bit 

If anyone has got any suggestions, I'd be very grateful to hear them. I 
have asked the publishers - no joy...
