The ornamental design for a portion of a glow-in-the-dark beverage lid, as shown and described.
FIG. 1 is an environmental top plan view of a first embodiment of a portion of a glow-in-the-dark beverage lid showing my new design; and,
FIG. 2 is an environmental top plan view of a second embodiment thereof, the oval shaped broken lines defining the limits of the claimed design and forming no part thereof.
The diagonal shading is representative of the color green and indicates that the region with such shading glows in the dark. The broken lines showing a cup lid in FIGS. 1 and 2 are illustrative only and form no part of the claimed design.
