Traces of affinity with Ichthyornisare, indeed, indicated by the moreor less markedly opisthoccelous dorsalvertebrae of the Limicolai and Gaviie;but Avhereas both these groups havean ectepicondylar process to thehumerus, and an extensor bony bridgeto the tibio-tarsus, neither of thesefeatm-es are present in the cretaceousgenus. The fenestration of the meta-carpus characteristic of the Gavia} is, moreover, wanting inIchthijornis. Hence it would appear that we must regard allthe above-mentioned features characterizing the existing groupsnamed as of co
