I'm looking at a section of my Animal Planet "Aquarium Care of Bettas" and there is a section called "The Betta Gallery" where they show the names of wild types along with their photos.. there is a photo of the chin of a reddish colored Betta looking up at a bubble nest... the name of the Betta type is "Betta m. eiern", I Googled it to look for more photos but it just shows these Bettas with a different name:

My question is, what does the "M. Eiern" look like?
