isolated specimen in question. Here I also came to an extraordinarily interesting and from point of view of reversionary trend-researches most precious observation to those I should not come never in the lack of my earlier (1976) investigations on a large series. Though the "first Jay-blue speculum" was not still in details white but on the whole very light, indistinct patterned; the squarebands were confused, Irregular and so scarcely observable. Taking together such was this "speculum" as if somebody would wish wash down with water its water coloured pattern but this operation did not succeed wholly. Considering that the whole "first speculum" of both wings have shown this surprising palness In spite of the fact that the other parts of the pattern and colouring of the bird were very conspicuous and cplourfull as of a normal one we may only come to the conclusion that the atavisme of the very suggestive pattern of the rectrices goes indeed with the becoming eclipsed or whitish of the "first jay-blue speculum" that is the specimen in question reverses not only with the characteristic pattern of the rectrices but of the wing feathers too to the lanceolatus species. Already the pattern of the head of the last named - after these - deviates only from that of the perfect, exact lanceolatus . But this is not wholly because the pattern of the head of the lanceolatus differs mainly from that of the garrulus that the black moustachial stripes were merged with the connected black pattern before, around, and behind the eyes. The pattern of the head of my atavistic specimen in question at least by its pattern around the eyes nearly connected, and attached to the moustachial stripes showes more definite black drawing as all the by myself up to this date investigated 351 specimens (1976). In my earlier of a similar subjected paper I have obtain a result that we must look for the ancestor of the Jay (Garrulus glandarius) in the Himalayan Garrulus lanceolatus species. This supposition has its justification in the results of my investigations those I have accomplished on a material represented by 351 specimens of 17 valid subspecies. Than I might only found my supposition on atavistic aberrations, demonstrated by the bustard wing and its neighbouring wing coverts that is by the "first jay-blue speculum" because I only have found sure and justificated platform concerning with this in the well distributed, and from a hudge area - from Northwest Africa to the Japan islands - originated investigation material. Now - for blind chance - such a single Jay arrived to my hands that said more by itself then the 16 (4.1 %) atavistic ones those I have found among 351 specimens. Namely, alone the perfect lanceolatus-like pattern of the rectrices is an extraordinarilly suggestiv reversionary mark too but add to this the eclipsing, whitewashing of the "first jay-blue speculum", and the appearing - at least in traces - of the black head patch besides those together are threetimes proofs in my earlier paper (1976) explained supposition.
