Length of LONG RAW field

How do I determine the length of a LONG RAW column?

SQL> desc blobs

 Name                            Null?    Type
 ------------------------------- -------- ----
 NAME                            NOT NULL VARCHAR2(128)
 BLOB                            NOT NULL LONG RAW

I have seen the utl_raw.length function but it does not like the LONG RAW datatype.
