1857 T. H. Huxley in Med. Times & Gaz. 21 Feb. 181/2 That part of the carapace which lies in front of it he [sc. Milne Edwards] terms the ‘cephalic arc’ while that which is behind is the ‘scapular arc’; but it will be better, perhaps, to adopt the terms ‘cephalostegite’, ‘omostegite’, as more in harmony with the general system of nomenclature which has been adopted.
1870 G. Rolleston Forms Animal Life 91 The anterior portion of the carapace is called the ‘cephalo-stegite’; and the posterior the ‘omo-stegite’.
1877 T. H. Huxley Man. Anat. Invertebrated Animals vi. 283 The carapace presents a posterior division (omostegite), obviously developed from the anterior thoracic somites.
