Ratnatunga et al. (1995) have recently proposed that an object, HST 14176+5226, in the "Groth-Westphal" HST survey strip is an "Einstein cross" gravitational lens. By chance, this object has been previously observed in the Canada-France Redshift Survey. The candidate lens, catalogued as CFRS14.1311, is an elliptical galaxy at z = 0.81. In addition, the spectrum shows a strong, spatially-extended, emission feature at 5342A that almost certainly originates from two of the four "lensed" images. We tentatively identify this emission line as Ly alpha at z =3.4. A less prominent emission feature at 6822A may be C IV 1549. Our data thus support the identification of this system as a new quadruple-image lens.
