Front tri- lobate, median lobe broadly triangular, pointed at tip, much more strongly produced than lateral lobes, latter narrow and rounded; in frontal view, median lobe showing a narrow, acute, strongly deflexed extension, present to a lesser degree on lateral lobes also. Orbital mar- gin forming a nearly straight line from lateral lobe of front to groove separating hepatic and epibranchial regions; outer orbital angle slightly produced into an acute tooth, latter deflexed like tip of frontal lobes and scarcely visible in dorsal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Allan Hancock Foundation.
