Soós, L.: Anatomy and systematic position of Campylaea coerulans

(JAHPÏLAEA COERULANS. the reproductive system shows all the peculiarities which characterise the Campylaeae, but this fact does not give sufficient reason for regarding II. coerulans as a Campylaea, since the construction of its gnawing apparatus proves that the directions of development of Campylaea and Hazaya have separated. That in spite of this the reproductive systems of that two genuses do not show more marked differences can be explained from the well known fact that those organs are always the first to change, which are more exposed to the transforming power of the conditions of life. According to HESSE « Hazaya » is a superfluous name, because BRUSINA employed the name « Vklovician for II. coerulans five years ago. But « Vidovicia

» is a simple name without any description, a «iiomen nudum», which according to the international rule of zoological nomenclature 1 can not be used, therefore the new genus must be named «Hazaya
