In our paper:

Jennrich, R.I. & Bentler, P.M. (2011). Exploratory bi-factor analysis. Psychometrika, 76, 537–549.

Eight lines from the bottom of page 548 should read

$$\frac{dB}{d\varLambda }=4\bigl(0,\varLambda _2\cdot\bigl(\varLambda _2^2N \bigr)\bigr) $$

We would like to thank James Steiger for pointing out this error.
