Kashira-gatame
(hold by the head)

"Tori holds Uke as in Hon-kesa-gatame but with these differences: Tori's right arm, instead of encircleing Uke's neck, passes under Uke's left arm so that Uke's shoulder and shoulder blade is lifted and Tori grips his own right knee in the popliteal hollow with his right hand, which is possitioned under the nape of Uke's neck. Tori's left leg is perpendicular to Uke."
