I’ve underlined the specific portion of your citation which directly supports what I stated:
**37. But the issue is pressed by saying (and this is the third axiom): the consent of the Churches is a rule of faith which even the Pope ought to follow, and therefore he should consult those who rule the Churches before he makes a definition in order that he may be certain about the consent of the Churches. I reply. The matter has come to its extreme point and we must accurately distinguish between true and false lest we suffer shipwreck in port. It is true that the Pope in his definitions “ex cathedra” has the same sources (“fontes”) which the Church has, viz., Scripture and tradition. * It is true that the consent of the present preaching of the whole magisterium of the Church, united with its head, is a rule of faith even for pontifical definitions. *** But from all that it can in no way be deduced that there is a strict and absolute necessity of seeking that consent from the rulers of the Churches or from the bishops. I say this because this consent is very frequently able to be deduced from the clear and manifest testimonies of Sacred Scripture, from the consent of antiquity, that is, of the Holy Fathers, from the opinion of theologians and from other private means, all of which suffice for full information about the fact of the Church’s consent.
038. Finally it must never be overlooked that there is present to the Pope the Tradition of the Church of Rome, that is, of that Church to which faithlessness has no access and with which, because of its more powerful primacy, every Church must agree. Therefore that strict necessity , such as is required for a dogmatic constitution, can in no way be demonstrated. It can happen that there be so difficult a case that the Pope thinks it necessary, for his own information, to ask the bishops, as an ordinary means**, what the sense of the Churches is, as he did, for example, in the case of the Immaculate Conception. Such a case, however, is not able to be established as a rule.

I can read. There is no need to annotate the text in such a way that is so harsh on the eyes as if I were illiterate. The text very clearly states that while it is true that the Pope requires the consent of the magisterium, it does not mean that the consent of the bishops is necessary, because the consent of the magisterium may be demonstrated by other means, such as from Scripture or Tradition. Furthermore, as section 38 makes clear, while the Pope may consult bishops, he is in no way bound to do so as a rule. Even the text you put in red from that section makes this clear by saying that consulting the bishops is an ordinary means, implying that an extraordinary means which does not involve consulting the bishops also exists.
