Inferior goods can have a downward sloping demand curve wrt to price. Then there will be CS (just as the case of a normal good). For a giffen good, there is a positive relation between the price and quantity. In this case, suppose the market settles to a price P. Here the consumer surplus will be the area above this price line and to the right of the demand curve.
