According to an agreement between the team of the General Catalogue of Variable Stars (GCVS; Samus et al. 2007-2014) and the Central Bureau of Astronomical Telegrams (BAT) reached in 1998, GCVS names for galactic Novae and some other variable stars of special interest can be given, upon BAT suggestion, between regular Name-lists of Variable Stars. These GCVS names are announced in IAU Circulars of Central Bureau Electronic Telegrams and then enter the next regular Name-list. This practice meets approval of the astronomical community, new names begin to be frequently used by researchers immediately after the variable's discovery.

Kazarovets and Samus (2013), lacking requests from the BAT for some time, announced GCVS names for 14 Novae discovered in 2011-2013. These names were also included into the 3rd part of the GCVS Name-list No. 80 (Kazarovets et al. 2013). After that, the BAT repeated the announcement of 8 Novae (Samus 2013a), and later (Samus 2013b), of three more Novae, with an additional announcement of one Nova that appeared later than those in our publication. Till the end of 2013, announcements of permanent GCVS names in BAT publications continued (Kazarovets 2013, Nakano et al. 2013a, 2013c, 2014, Nishiyama et al. 2014a, Samus 2013c), with names announced for 7 stars. Because of this, we did not follow our plan (Kazarovets and Samus 2013) to announce new permanent designations in the Astronomical Circular (http://comet.sai.msu.ru/ gmr/AC/index.html), an electronic journal of the Eurasian Astronomical Society and Sternberg Astronomical Institute (Lomonosov Moscow University). However, very soon the BAT announcements of GCVS names stopped again. Also, some rare-type variables were first announced not in the BAT resources but elsewhere. Thus, of a total of 13 Novae or stars of rare types deserving quick naming, 6 remained not announced.

We are now finishing preparation of the next, 81st Name-list of variable stars. As a part of this work, in the present paper, we announce permanent GCVS names for 11 galactic Novae and two variables of other rare types. The announcement lists all rare-type stars named after our list in Kazarovets and Samus (2013). Table 1 presents relevant information. Asterisks means magnitudes from unfiltered CCD photometry. References are given in the last column.
