Theytus Books (in Canada) have a call out for 'Science Fiction and Speculative Fiction' by Indigenous authors. The anthology is only accepting physical submissions (oh c'mon guys, it's 2014!) but the pay is excellent at $250, and it is likely that the narrow focus and eligibility will make it worthwhile jumping those paper hoops. The deadline is June 15, for fiction up to 5,000 words. Get writing!
The only guidelines link I have is an image, which will be difficult for people with sight issues. Check them out here for mailing address and further information: http://www.raymondboisjoly.com/image/76912023430
