     Serpens is unique among the constellations in having two parts which are not connected -- Serpens Caput (the head of the serpent), and Serpens Cauda (the tail) -- but are separated by Ophiuchus, the serpent holder. The Bayer designations of the two sections are based on the single, contiguous constellation of antiquity, but their current separation means that the constellations bordering one part are somewhat different from those bordering the other part:

Serpens is one of the 48 ancient constellations recorded by Ptolemy.
