This species is evidently quite near to the IJ. thalassina. I only-

very broad and low, with a median superior projection. The frontal is transversely

 grannies, which are slightly largest centrally. There is a weak anterior gular fold,

 and is covered with whorls of small weakly keeled scales. The scales on the
