Fig. 1. -Hypopygium of male Qlussina, as seen when closed ; the dotted lines indicate the position of the superior claspers beneath it. that its ventral surface together with its various and complicated structures are displayed. These appendages are : 1. Superior Claspers {sc in all the figures). The position of these organs when the hypopygium is closed has already been described and it is indicated by the dotted lines in fig. \sc. These organs can be erected to an angle of varying degrees ; but in life they are never extended backwards so as to lie in a horizontal position or in the same plane as that of the abdomen, and considerable pressure is necessary to bring them into this position (see dotted lines in fig. 2)..
