elegans - No distinct pattern above head
Cyrtopsis - black patches behind the head
Aspidoscelis sexlineata vs. tesselatus/tigris
sexlineatus - six lines on dorsum
tesselatus/tigris - checkered pattern
Aspidoscelis tigris vs. tesselatus
tigris - uniform gular fold scales

Anaxyrus woodhousii vs. boreas
woodhousii - distinct cranial crest
boreas - NO cranial crest,
A debilis vs punctatus
debilis - small size, flattened head, small paratoids, weak cranial crests
punctatus - narrow snout, flattened head, weak cranial crests, oval paratoid glands
Anaxyrus cognatus
3-sided cranial crest
symmetrical oval pattern
