The ninth form of the Divine Mother is Siddhidatri Devi......

  The ninth form of Maa is Siddhidatri, which is also an aspect of Mahalakshmi. She is seen sometimes sitting on a lotus or sometimes mounted on a lion. She is four armed. After having performed the worship to the other forms, the devotee then starts the worship to Her. She is One with the forces of sustenance and salvation of Mahavishnu and so She is the One who delivers all forms of success. “Siddhi” means power. For “siddhi” to become “riddhi” (prosperity) one needs “buddhi”, i.e. intelligence.  So Mother Siddhidatri gives also wisdom. Once we have our mind surrendering to the Divine, She blesses us with ultimate success.
