Not much representation on these for BG in the West, so I thought I'd throw one up that I found in my backyard, tonight. I also note that the spot on this specimen's surface is unusual among images in the guide. I still have the specimen if anybody wants a closer look at it. Photos aren't great, but one can only devote so much of one's life to taking photos of tiny symphyla. I put my 20 minutes in! ;)
