The palatines too aredevoid of an internal lamina, and the angle of the mandible isrecurved and produced ; it is enormous, extended upwards, inTetrao. In the typical gallinaceous birds the maxillo-palatinesare generally small or even obsolescent. In Gallus hanhivathey are triangular plates of fair size; in Tetrao urogallus(fig. 152) they are small, narrow, backwardly projectingplates, not quite so long and thin, and not so curved as thoseof Talegalla. In Ptilopachys they are somewhat inter-mediate ; in CalUpepla californica they are still longer. InNumida and Meleagris they are much the same. The lacrymals are not large,^ and have a feeble or aborteddescending process. It
