	abstract = {Some unique cases of bicephality in Tegenaria atriea C. L. Koch are described. This phenomenon is known to be the result of broadening and then sagittal bifurcation of the anterior germ band. In consequence there develop two head tagmae. equivalent if the germ band divides symmetrically or non-equivalent if the division is asymmetrical. The bifurcation of the germ band can be shallow. which produces two heads, or deep. which may lead to the development of so-called "Siamese twins". A less frequent cause of bicephality is bifurcation across the anterior end of the germ band in the horizontal plane. Then two head somites develop, the main head, usually with a normal structure. and a so-called accessory head. usually incomplete. situated one above the other. In the authors{\textquoteright} opinion the study of the morphology of the anterior body in bicephalous individuals provides exceptional opportunities for studying the inter-relations between the functioning of the particular parts of the brain and widely understood behaviour of spiders.},

	abstract = {The opisthosoma of Tegenaria atrica is characterized by a high mor- phological stability, as it is exceptionally resistant to the teratogenic effect of most abiotic factors except temperature. The least frequent opisthosomal anomalies found in our experimental material were disturbances in the colouring of opisthosoma. Another rare anomaly was the elongation of the postspinneret zone of the opisthosoma, resem- bling the postabdomen of other arachnids. The occurrence of a much narrower elonga- tion, sometimes with traces of segmentation, resembling the postabdomen the advanced spider, can be interpreted as a specific atavism. An equally rare anomaly was the presence of two independent anal orifices in the postspinneret zone. All the above- described anomalies appear extremely rarely, and some of them are related to the atavistic characteristics observed in the spiders{\textquoteright} ontogeny},

Koch, in which polymely was experimentally induced by heating the embryos with alternating temperatures of 14[degree]C and 32[degree]C. In one case the increase in the number of appendages was associated with simultaneous increase in the number of mid-gut caeca. A peculiarity found in the other monster was the absence of epimorphic abilities in its polymelic appendage. A close histological and anatomical analysis of the two monsters has verified the rule that the best indicator of any developmental changes are disturbances in the neuromerism of the nervous system. Other organs, particularly those of non-metameric origin, can exhibit a very pronounced morphological stability.},
