Occurrence: This species is found as a very rare form in the uppermost beds of the Mendez, becoming abundant at the base of the Velasco and but little less abundant throughout the lower part of the Velasco. In the literature it appears as G. triloba Reuss, but unlike that species it has no secondary apertures.
