This is "One of a pair which stood at the entrance to the king's tomb". Let's have a closer look at Peribsen's name:

"So far as could be checked, only one king took a separate Seth name besides his Horus name. This happened in the 2nd dynasty. The Horus name of this king was Sekhemib and his Seth name was Peribsen. We are justified in calling it a Seth name, because the Seth-animal is depicted over the serekh, instead of the usual Horus falcon." (From _Seth, God of Confusion_, by TeVelde, page 72)


_Encyclopedia of the Egyptian Pharaohs_ by Darrell Baker gives the hieroglyphs (page 363)

"The name of Peribsen can be translated. Like so many Egyptian names, it contains a verbal sentence. Pri-ib-sny means "leurs sentiments (leurs désirs) à tous deux se révèlent. Reverso.net gives for this : "Their feelings (their desires) in both show themselves".
(I will be hunting other translations...)
Meanwhile, "The suffix-pronoun sn or sny refers to the two gods Horus and Seth."
