. Key to North American birds [microform] : containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland. Birds; Ornithology; Oiseaux; Ornithologie. 562 SYSTEMATIC SYNOPSIS. — COLUMBJE — rERlSTEli^. seems best to draw the liue, if one must be drawn, so as to incliitlc the Pterocktea in Cohimha, and leave the Cracida and MegapodidcB with GallitnE. The Sand-grouse (better Sand-pigeoUM), or Pterocletes, re[)resent the inoscuhitiou of the two series. Tliey are terrestrial Columbines, uiodiiicd for a grouse-like life; the digestive system is fowl-like (cujca several inches long, etc.); but the jiterylosis, the sternum and Immerus, the cranial and many other characters, are pigeon- like. The only alternative to reference of Pterocletes to the Columbine series is their elevation to independent ordinal rank, as proposed by Huxley. The Columbee, as above indicated, are intended to be made conformable to Huxley's Periste- romopluc plus Pterocletes. Assuming the imperfectly-known extinct Dodo, Didus ineptus, to have been a modified Columbine, and considering the Pterocletes to rej)re8ent a rasorial modi- ficiitiou of the Columbine series, the Order Columbee may be separated into three groups, or suborders, Didi, Pteuocletes, and Pehister^, the first two certainly, the last probably, of a single family. The Peristerce alone are American. 9. Suborder PERISTER^ : True Columbine Birds. (Equivalent to the Peristeromorpha; of Huxley; the Gemitores of Macgillivray, or Columhai proper of most autiiors ; the Gi/rantes of Bonaparte, jdus Uiduiiculus; Columba; of Garrod minus Pterocletes; PiiUastrce of Liljeborg miims Crackltc and Meyapodidw.) Skull Bchizognathous, schizorhinal; basipterygoids prominent; angle of mandible not produced; rostrum externally as above said. Sternuni doubled-notched or notched and fenestrate, on each side; pectoral crest of humerus salient
