No specimens have been collected that might represent ros- tral, pineal, or orbital plates. This is, of course, purely negative evidence, but perhaps sufficient collecting has been done so that it has some weight. The following points may be interpreted as supporting the view that the Cardipeltis shield is only a dorsal disc, not the complete dorsal shield: 1. The absence of a pineal macula. This is not conclusive since the macula is indistinct in some Cyathaspidae, as Dinaspidella and 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 Denison, Robert H.
