   To wit; namely; videlicet; -- often abbreviated to sc., or
   ss.
   [1913 Webster]
    

SCILICET. A Latin adverb, signifying that is to say; to wit; namely. 
     2. It is a clause to usher in the sentence of another, to particularize 
that which was too general before, distribute what was too gross, or to 
explain what was doubtful and obscure. It neither increases nor diminish the 
premises or habendum, for it gives nothing of itself; it may make a 
restriction when the preceding words may be restrained. Hob. 171 P. Wms. 18; 
Co. Litt. 180 b, note 1. 
     3. When the scilicet is repugnant to the precedent matter, it is void; 
for example, when a declaration in trover states that the plaintiff on the 
third day of May was possessed of certain goods which on the fourth day of 
May came to the defendant's hands, who afterwards, to wit, on the first day 
of May converted them, the scilicet was rejected as surplusage. Cro. Jac. 
428; and vide 6 Binn. 15; 3 Saund. 291, note 1, and the cases there cited. 
This word is sometimes abbreviated, ss. or sst.
