Namaskaram Bhaskar-ji,
The book was published in 1911. I did find a few mentions of avidya in the latter parts of the book but failed to particularly note them (and think they were mentioned in the sense of ignorance). Will pay more attention henceforth.
At least till Chapter 1, he was mainly focused on noting primarily the usage of maya in the scriptures and bhashyas, and that too with reference to literature preceding and till Shankara. But he did have this:
"
From Sarikara s time downward the phraseology
of the Vedanta was more and more settled technic
ally, and even modern writers on the Vedanta use
the word "
maya
"
in the same sense of
"
illusion
"
which was so clearly brought out by Sankara.
After his time there has not been any desire to
change the meaning of the term by a different usage.
Hence it will hardly be of much use to examine the
later Sanskrit texts on the Vedanta in order to find
out the word "
maya." In the first place,
it is
exceedingly difficult to do so, since the later litera
ture is so varied, vast and undefined in extent
;
secondly, the later Vedanta is in many cases mixed
with the ideas of the Sankhya, Buddhism, etc.
;
and
thirdly, even if we were to succeed in collecting
all
the more important modern works on pure Vedanta
and were to collate the passages containing
"
maya
"
in a similar way, it would scarcely be of any profit,
since, as we have already said, the modern usage of
the term is in no way different from that of Sankara.
A glance through such works as the Pancadati,
the Veddntasdra, the Veddntaparibhasd,
the Atma bodha, the Vivekacuddmani, etc., will amply endorse
this fact. We may, therefore, safely
close our sur
vey of the meanings of the term when we have come
down to Sarikara s time."
So, a bit confusing since he says the later Vedanta is in many cases mixed with Sankhya etc. but also thinks the term maya is fundamentally used in the same way as Sankara. It would be fair to say he did not anticipate the conflict over the word avidya that came after SSS, otherwise might have written a second treatise on "Doctrine of Maya vs Avidya in Advaita Vedanta".
I also noted a couple of his BSB references for maya also had or hinted at avidya. (Not arguing for their equivalence, just making note.)
------------------
BSB I.iii.19: "The theme of this Sariraka text is this: The supreme Lord is but one - unchanging, eternal, absolute Consciousness; but like the magician He appears diversely through Maya, otherwise known as Avidya (ignorance)**. Apart from this there is no other Consciousness as such."
Swami Gambhirananda
**:
Ratnaprabha makes no distinction between Maya and Avidya, though it is admitted that the juxtaposition of the two terms implies a difference between the two powers of Maya - of covering and disturbing - which fact may give rise to different terminology. But others would maintain that Maya refers to cosmic nescience and Avidya to individual ignorance. [Refer to

BSB I.iv.3: "Should we admit some primal state as an independent cause of the world, we shall be opening the door for the theory of Pradhana as the cause. But this primal state is held by us to be subject to the supreme Lord, but not as an independent thing. That state has to be admitted, because it serves a purpose. Without that latent state, the creatorship of God cannot have any meaning, inasmuch as God cannot act without His power (of Maya), and without that latent state, the absence of birth for the freed souls cannot be explained.
Why?
Because liberation comes when the potential power (of Maya) is burnt away by knowledge. That potential power, constituted by nescience [is sanskrit word Avidya here?], is mentioned by the word unmanifest. It rests on God, and is comparable to magic.
This thing, that is avyakta, ... sometimes it is called Maya as in, "Know Maya to be Nature and the master of Maya to be the great God" (Sv. IV. 10). That Maya is surely unmanifest, for it can neither be ascertained as real nor as unreal..."
