A transference neurosis corresponds to a conflict between ego and id, a narcissistic neurosis corresponds to that between between ego and super-ego, and a psychosis to that between ego and outer world.

Neurosis is the result of a conflict between the ego and its id, whereas psychosis is the analogous outcome of a similar disturbance in the relation between the ego and its environment (outer world).

We can postulate that there must be diseases founded on a conflict between ego and super-ego. Analysis gives us the right to infer that melancholia is the model of this group, and then we should put in a claim for the name of "narcissistic psychoneuroses" for these disorders.
