(See p. 428, fig. 379.) These combinations of characters may be contrasted for the purpose of dividing the great group Passeres into two sections, conventionally denominated sub-orders. 1. Suborder PASSERES ACROMYODI, OK OSCINES: Singing Birds. Syrinx with four or five distinct pairs of intrinsic muscles, inserted at the ends of the three upper bronchial half-rings, representing the acrumyodian type of voice-organ, and constituting a highly complex and effective musical apparatus. Side of tarsus covered with a horny plate meeting its fellow in a sharp ridge behind; front of tarsus also sometimes laminate. Prima- ries ten, with the first short or spurious, or apparently only nine. Here belong all the North American famihes of Passeres, with the single exception of the Tyrannid(B, or Flycatchers, which are clamatorial (mesomyodian). The only North American exceptions to the diagnosis given are afforded by the Alavdidce, or Larks, and certain Troglo- dytidae, which, with an oscine syrinx and wing-structure, do not have a bilaminate tarsus. Of our 394 Passerine species, no fewer than 363 are Oscine. The name is the Lat. os'cen, in ii. pi. os'cines, divining-birds — those whose notes were regarded as augural. It is a question, which one of the numerous Oscme families should be placed at the head of the series. Largely, perhaps, through
