[Advaita-l] Is there a Cityupanisad?

[Venkata sriram P]

Namaste Krishnadas Ji,
 
If you can type the excerpts from the commentary, it would be of immense help.
 
I can see only 2 options here:
 
1) The word *city* might be a true translation of the word *pura* in sanskrit.  So, it could
    have been Tripura Upanishad.
 
or
 
2) It could have been a sandhi of *iti+upaniSad* which is read as *ityupanishad*. 
    The word *C* could be either a typo or parenthesis (left bracket)
 
This is my understanding as i havn't gone through the book.
 
regs,
sriram
