1959L. H. Hyman Invertebrates V. xix. 229 Three groups of coelomates—Phoronida, Ectoprocta, and Brachiopoda..have in common the possession of a lophophore. A relationship..was first surmised by Caldwell (1882), but it remained for Hatschek (1888) to express this..by making them classes of a phylum Tentaculata... The name Lophophorata would have been far more appropriate, and here the three groups in question will be referred to as the lophophorate phyla, or lophophorates. 1962D. Nichols Echinoderms xiv. 173 There is some evidence that the lophophorate body is subdivided into three regions. 1972P. A. Meglitsch Invertebr. Zool. (ed. 2) 672/1 The preponderance of evidence points to the lophophorates as deuterostomes. 1979Nature 8 Nov. 135/2 H. and G. Termier..envisaged the evolution of coelomates as involving an early separation of echinoderms from lophophorates and chordates. 1983E. C. Minkoff Evolutionary Biol. xxvi. 465/2 All lophophorate phyla have a simple digestive tract, complete with mouth and anus. |
