Ha! Ha! Found it. Here it is :
[Lupin is speaking to Harry]
"Look after yourself", said Lupin, shaking hands all round and 
reaching Harry last. "And listen..." he lowered his voice while the 
rest of them exchanged last-minute goodbyes with Tonks, "Harry, I 
know you don't like Snape, but he is a *superb Occlumens* and we all -
 Sirius included - want you to learn to protect yourself, so work 
hard, all right ?"
(OoP, chapter twenty-four).
Maybe Lupin is only skilled in Leglimency and tried to use it 
with/against Snape who happened to be a master Occlumens ? Or the two 
of them practiced together ? What do you think ?
