A paper by the author  recently published in this journal unfortunately missed to cite an important theoretical study of BnNn (n = 3–10) neutral clusters by Martin et al.  in which the molecular geometry and vibrational frequencies of the D9h-symmetric B9N9 monocycle were predicted. Hence, the author's introductory statement in Ref.  that the “stability and symmetry [of B9N9] are yet unknown” is incorrect. The author wishes to express his sincere apologies for the oversight. Closely related to the work of Martin et al.  are a theoretical study of the BnNn + (n = 3–10) cationic clusters by Giuffreda et al.  and a paper by Strout  on the relative stability of rings and cages of the BnNn (n = 8–11) neutral clusters. Finally, along with the theoretical studies cited in Ref. , the author wishes to add Refs. [5–10] containing computational results for the cyclocarbon (C18) molecule and its cation.
