No notes of the 1871 issue are known to have survived except for two $20's. A register of surviving notes (a very brief listing; all notes in institutional collections) was published in the July 2000 issue of the CPMS Newsletter; also several articles relating to the history and notes of the Exchange Bank of Yarmouth, which was the featured bank of that issue.
From one of these articles we learn that on 16 Oct. 1871 the American Bank Note Co. received orders from the Bank to alter the date on the $4.5.5.10 plate to July 1st 1871 and then to print 2000 sheets, numbered 3001 to 5000 in red. The notes on these sheets were further requested to have "Canadian Currency" typed on each end of the face, also in red. So, the short answer to your question is "No, they do not lack the inscription".
(You will not find the $4 of this issue catalogued because nothing whatever is known to have survived of the issue, not even a proof.)
If you wish to follow up, you can probably still get the back issue of the Newsletter from the CPMS general secretary at a nominal cost.
