...and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
"particularly" is typically understood to require particularity in the warrant. One cannot say "here is a search warrant for the Island of Manhattan, go catch the bad guys."
The argument here I think is that since pen registers typically require only reasonable suspicion, a warrant is not required anyway, so the fact that it doesn't look like a valid warrant to me is probably just intended to be for the benefit of the telco.
