When I run in a terminal w to see the ssh logins just-in-case I see this:

USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
 user  tty7     :0               08:14   10:32m 44:10   0.50s gnome-session
 user  pts/0    :0.0             09:15    9:30m  0.24s  0.24s /bin/bash
 user  pts/1    :0.0             14:14    4:32m  0.20s  0.20s bash
 user  pts/5    :0.0             18:27    9:24   0.28s  0.28s bash

 user  pts/8    :0.0             18:37    0.00s  0.22s  0.00s w

Pseudo-Terminal Slave


They're usually xterminal/gnome-terminal/terminator sessions.

pts/ refers to a pseudo terminal (one that is not a physical terminal), See http://en.wikipedia.org/wiki/Tty_%28Unix%29
