ZaTophus californianus 
This species was not censused. The females continue to abort foetuses. 
Sixteen of the premature (aborted) animals were found. All were in natal 
pelage; during the March visit the aborted animals were not yet furred. I 
assume this to be an abnormal situation, but can offer no explanation for 
the occurrence.
