Likely the only way to potentially recover this would be if Bittrex adds that token, and that also under the assumption that you have the same deposit address at Bittrex for all ERC20 Tokens, which probably is not the case. My only suggestion is to open a ticket and wait patiently.
Looking at your transaction, I think this is the one you are trying to show: https://etherscan.io/address/0xb3c12bb3059c5e28544a1e10c6c8cdc9389eda41#tokentxns
