Riley on Birds of the Mount Robson Region

The rules governing family and subfamily names are not given but we fail to see how the name Peltohyatince can be used when Peltohyas has been rejected in favor of Eudromias for the only species of the group, E. australis, which is the monotypie type of Peltohyas!We regret exceedingly that we cannot endorse this Check-List for general use.Aside from all questions of nomenclature, it would serve a valuable purpose as a conservative list of Australian species and subspecies; but here it fails, in-as-much as the lack of synonymy makes it difficult or impossible to ascertain with which forms the many recently described races have been united.--W.S. Riley on Birds of the Mount Robson Region.•--During July, August and September, Messrs. J. H. Riley and Ned Hollister.ofthe U.S. Nat•ional Museum joined the expedition of the Alpine Club of Canada to the Mr. Robson region of the Canadian Rockies, for the purpose of making a general survey of the fauna and flora.The general account of the expedition has been published in volume IV of the Club's Journal while this special number contains the scientific report•s.Mr. Hollister contributes an account of the mammals, and a list of the reptiles and batrachians, Mr. Riley reports on the birds and Mr. Paul C. Standlcy on the plants.The route inckuted Jasper House, Henry House, then through the Yellow head Pass and up the Moose River to Moose Pass and Moose Pass branch of the Smoky River, with a stay on the Fraser River east of Moose Lake on the return.Seventy-eight species of birds are listed including a Song and Fox Sparrow which Mr. Riley has described as new in a previous proper.Bohemian Waxwings were evidently breeding on the west fork of the Moose River, as a specimen obtained July 14 contained an egg nearly ready to be deposited.These birds were much paler than winter examples and similar individuals undoubtedly, as Mr. Riley suggests, formed the basis for Reichenow's subspecies Bombycilla garrula.pallidicepsfrom Shesly River, B. C. Mr. Riley found Zonotrichia gambeli and Z. leucophrys apparently nesting in the same spot while Junco hyemalis hyemalis and J. oreganus sh•feldti were nesting together at Henry House, Yellowhead Pass and at the foot of Moose Pass, with no sign of intergradation.On the strength of this evidence he ranks them as distinct species.Penthestes hudsonicus columbianus is recognized as a distinct form and Lagopus leucurus peninsularis is considered as no more distinct from true leucurus than is L. 1. altipetens, the two being respectively the northern and southern extremes of the White-tailed Ptarmigan.Mr. Riley contends with apparent justice that both or neither should be recognized.• Birds Collected or Observed on •he Expedition of the Alpine Club of Canada 0o Jasper Park, Yellowhead Pass, and •Vlount Robson Region.By J. lt.Riley.
