At one point I visited all of the places where they should be, though I don't think I have more pictures than the two you already have. I remember finding a couple more in the neighborhood west of Tufts (and also assuming that the two markers that should, by rights, be inside Tisch Library were gone), and not finding the one inside the 38/93 interchange. The map I see up in places that deliver food actually has the boundary marker locations and numbers marked on it in tiny print.
The only Cambridge/Somerville marker I know of is #17, at White Street and Elm Street, but it's embedded in the sidewalk. I've looked for more in the Davis area, and while it's straightforward to use the parking permit signs to find the city line I haven't found more markers. The markers are also all over on the canonical biking routes through the western suburbs.
