Since the other sloths are under "mylodon," I don't think it matters much which name order we use for the Tree Sloth or Sloth, Tree.
I'm not sure I'd put "Snake" in front of the three snakes you have there. It's not like the MM has Bird, Roc and Bird, Giant Eagle, etc.
I think the bigger issue is the groupings we should post. I really strongly think we should be posting finished monsters (and not rushing to finish any to be posted in a particular week --- we have a lot of critters backed up). So I don't want to post the weresloths and then wait to post the tree sloth. Let me propose the next two groups to be
Jaguar, Spotted Lion, Dire Lycanthrope, Leopardwere, Wereleopard, Werelion, Weresmilodon, Dire Otter, Potamotherium, Leomarh [Felines and otters]
Tree Sloth, Giant Weresloth, Ground Weresloth, Tree Weresloth, Wereweasel, Werebison, Werecamel, Weresheep, Werebadger, Silkie [Shapechangers and associated]
Save the snakes for when they're all finished.
