Determining emails of user names in a particular group within a Portal

[Anonymous User]

I'm trying to do the basic work flow below.......

1. Connect to portal
2. List Groups
3. Connect to a specific group
4. List all users and their associated emails

1-3 is not shown, I'm not having issues with that. What I am having trouble with is listing emails for a specific group of users. I can't find in the documentation where the email property exists. You can see these in update and create methods but how can I just access the email on file? 

I just want to access like what I think like 32 and 34 should work.
