Animals coming from the Mt. Humboldt area of Grande Terre can be quite variable as pictured to the right. They most commonly tend to have an olive-green background with brown markings and white blotches along the sides that are typically in the form of spots rather than solid bars, which can show characteristics of forms found to the north (Poindimié) and to the south (Yaté).
The distance between the eyes is narrow in comparison to Yate and their shorter snout can appear almost beak-like.
To date, the largest captive animal from this locale is 420 grams with variable background coloration.
