Before classifying, we define a malaprop as a word used in the belief that it has the meaning really belonging to another word that resembles it in some particular.
1. Words containing the same stem, but necessarily, or at least indisputably, distinguished by termination or prefix.
[...]
The working of the staff at the agent’s disposal was to a great extent voluntary, and, therefore, required all the influence of judicial management in order to avoid inevitable difficulties.—Times. (judicious)
A not uncommon blunder.
By all means let us have bright, hearty, and very reverend services.—Daily Telegraph. (reverent)
Not uncommon.
He chuckled at his own perspicuity.—CORELLI.
If the writer had a little more perspicuity he would have known that the Church Congress would do nothing of the kind.—Daily Telegraph.
Perspicuity is clearness or transparency: insight is perspicacity. -uity of style, -acity of mind. Very common.

2. Words like the previous set, except that the differentiation may possibly be disputed.
[...]

Our Correspondent adds that he is fully persuaded that Rozhdestvensky has nothing more to expect from the complacency of the French authorities.—Times. (complaisance)
Complaisant is over polite, flattering, subservient, &c. Complacent means contented, satisfied.

With continuance the meaning would be that the already published volumes (of Diderot’s Encyclopaedia) were to be destroyed; but the meaning intended is that the promised volumes were not to be gone on with—which requires continuation. Again, the next two extracts, from one page, show Mr. Morley wrongly substituting continuity, which only means continuousness, for continuance.
[...]
The inconsistency and evasion of the attitude of the Government.—Spectator.
Evasiveness the quality: evasion a particular act.
[...]
4. Words having properly no connexion with each other at all, but confused owing to superficial resemblance.
[...]
In the present self-deprecatory mood in which the English people find themselves.—Spectator. (self-depreciatory)
Depreciate, undervalue: deprecate, pray against. A bad but very common blunder.
‘An irreparable colleague,’ Mr. Gladstone notes in his diary.—MORLEY. (irreplaceable)
No dead colleague is reparable—though his loss may or may not be so—this side the Day of Judgement.
