Theres even a lecture at an astro gathering called the Bart Bok memorial lecture. On the HST pic they mention a South African astronomer A.D.Thackaray who apparently first spotetd these particular globules, see

I know ones in the Rosette nebula are referred to as Bok Globules. An AAT pic of IC2944 also refers to them as Bok Globules.
