M. bruesi can reach a snout-to-vent length (SVL) of about 83 cm (33 in). Dorsally, it is blue-gray to brown, with lighter lateral stripes. Ventrally, it is whitish.[2]
The preferred natural habitat of M. bruesi is forest, both mesic and xeric.[1] It can be found on the ground, and in bushes, where it sleeps at night.[citation needed]
M. bruesi has been recorded in the southwest corner of Saint Vincent and is widespread all over the Grenadines islands.[citation needed] It is also found on the southern half of Grenada, which is the farthest south it is distributed.[citation needed] It has been introduced to Barbados,[1] probably around thirty years ago, where it has been incorrectly identified as Liophis perfuscus.[citation needed]
