CommentVenomous!

Diagnosis.—A coral snake of the genus Micrurus with the normal body form and arrangement of scales; pattern extremely complex (fig. 34), with black rings in groups of three (triads), the rings subequal above, the outer rings in each triad narrowed below, with corresponding widening of the red ring intervening between triads; the outer black rings of each triad separated from the middle one by narrow yellow rings split by a black one; the triad pattern lost on the tail, where equally wide black rings are separated by double yellow rings. The black head crossed by a narrow yellow ring behind the eyes and behind the parietals, the two black portions of the head with the nuchal ring composing a somewhat obscure first triad. The red rings often divided by a narrow black ring [from SCHMIDT 1958].

Original description (free translation from the French).—Our museum has received five specimens of this species from Mexico, all identical in pattern. The snout is black; behind the eye, a white band extends onto the postoculars and the anterior part of the parietals, interrupted medially. Except for the fifth and sixth upper labials, the third and fourth lower labials, and the chin shields, which are white, the rest of the head is black as far as the neck. At this point there is a series of white scales arranged like a necklace of pearls; behind this there is a large black triangular marking, followed by a light band (red), extending for three or four scale-lengths, in which the tips of the scales are black. From this point there are thirteen or fourteen groups of triple black bands [triads], which tend to be confluent beneath, each [individual] band extending over three or four scales and separated from each other by a single series of white scales [really by a double series, cf. plate]. The spaces between the triads are 4 scales long, and there are large black spots in these [red] bands on the ventral surface. The tail is black, with six white rings formed by a single series of scales [from SCHMIDT 1958].
