Strongylogaster P. PEARSON 1951-1952 by the skin of the belly. This hole was 4 yds from where ♀3515 was caught Jan. 14. So far this is only record of 2 adults in same burrow- system. Record is as follows: Jan. 13-14 - adult ♀3515 caught in trap overnight (probably caught late evening or early evening because died of exposure & walking) Jan. 15.- free digging at same burrow, trap spring but nothing in it Jan. 16 - " " " 4 yds away in a.m. set trap and caught pregnant ♀3520.
