Foot.—A comparison of the relative length of the pha-langes of the third digit appears to afford another characterfor the discrimination of the Striginse and Buboninse. In Strix (fig. 3, A) the first phalanx of that digit is markedlyshorter tiiau the second phalanx. Fig-. Jot^v/ Biglvt foot oi Baho benjalensis (nat. size). In Bubo (fig. 4j A) and in the other genera the two pha-langes in question are subequal. 3i0 Mr. F. E. Beddard on the ^ Applying tliis test to Heliodilus, it confirms the justice ofProf. Milne-Edwardss views of the affinities of that bird. Inthe illustration of the skeleton which he gives^ it is quiteobvious that the proportions of the two first phalanges of thethird digit are those of Strix. The illustration of PhotodUus is not sufficiently accurateto admit of a statement with regard to this point. Theskeleton was apparently defective. The principal osteological characters of the genus Strix,aud which apparently distinguish it from all others, are thefollowing :— (1) The skull is relatively long and narrow. (2) The palatines are straight, nearly parallel to each other; they are of approximately the same width throughout;they almost conceal the underlying maxillo-palatines,which are broader from above downwards than fromside to sid
