.AlBSTRAQI': The brachiopods of the family Thecideidae Gray from the Middle OXfordian of 1Ba1t6w (NE lMesozoic mugtn of the IBoly Cross IMts), j.nclucHng two species, PraelacazeUa ulmensis (Quenstedt) and Praelaca.zeUa baltOViensiB sp. n., of the BUbfamUy !l.Al<:ezellln&e, one specieB, Agerinella 1111'ata Piajaud & Patrulius, of ·the subfam.fty lDa'Vlidsoneninae and one species, MoorreUiraa Beptat4 (Moore), of the subfamily lMoorell1ninae are described. These species indicate very shallow-sea conditions that predominated in the basin d.n this area of the margin' of the Holy

.. Remarks. ·~The specimens under study completely correspond to Thecidea·

have been expressed by !Pajaud 1(1986b) concerning the purposefulness (If madntaining the species Thecidea seprota Moore and Moorel~ina. dundrensis (Hollier), since the- specimens of both species, displayed such a high degree ·of similarity that one could suppose tha·t TheCidea. septata !Moore was a j-uvenile fOND of ~ooremna d~ndrensis (Rollier). This was the reason why this author suggested·a tentative introduction.
of either a combined name MooreUina septata aff. dundrensts, or "Thecidea" septafia Moore. Not having at his disposal ;any new arguments in this discussion, the present writer abides by a taxonomy used by E1l1ott (1953).

W oksfordzkdch wapieniach koralowych w iBaltowie {p6!nocno-wschodnie obrzeienie mezozoiczne G6r Swi~tokrzyskich) wyst~pujll stosunk()wo liczne okazl rzadkich brachiopod6w naleh\cych do rodziny Thecideidae Gray. Wzgl~dnie dobr1 stan zachowania pozwolil na przeprowadzenie badan morfologii zewn~trznej i wew- n~trznej tych braciopOd6w, kt6re sll reprezentowane przez cztery gatunki: Prae- lacazeUa uZmensis {Quenstedt), Praelacazella baltovienBis sp. n., Agerinella Zllrata Pajaud & Patrulius oraz MooTeUina septata l(Moore). Opisane gatunki, podobnie Jak caly zesp61 faunistyczny wyst~uJllcy w rozpatrywanych osadach, wskazujll na pa- nowanie w 6wczesnym zbiorniku warunk6w bardze plytkomorskieh (por. Ronie-
