Transversalis muscle has been partially cut away to expose transversalis fascia ; sper- 

 matic cord is seen issuing from internal abdominal ring, covered by infundihuliform fascia, 

 which has been artificially distended ; anterior layer of femoral sheath has been removed, 

 showing femoral vessels and canal ; anterior wall of sheath of rectus has been opened above 

 upper part of muscle removed and posterior wall of sheath exposed.
