Sub Fig. 2iZ- Left tliree-(|uartering view of the fuicula of Nycticorax violaceus. adult.) Fig. 34. Same view of the os fitrcula of Ardea caniiidissiiiin. Both natural size from the specimens. It will be seen that these trochlea are so placed as to be slightly forwards, and in a less degree concave behind, where they come up to nearly the same points on the shaft, the middle one being rather the lowest. Moreover, the mesial grooves that mark them are here carried up to their very terminations. This posterior aspect of the distal extremity also shows the foramen for the anterior tibial artery in full view. Above these trochlear, and to the inner side, the cir- cular facet for the first metatarsal is found. These three long bones of the pelvic extremity of Ardea Jierodias have the following measurements in the adult : the femur, measured from the highest point on the trochanterian ridge to the lowest point on the outer condyle, is cm. long, the tibia, cm. and the tarso-metatarsus, cm. long, measuring from the highest point on the intercondyloid tubercle to the lowest point on the middle trochlea. We may add here that the length of the fibula which is but 9 cm., being one and a half centimeters shorter than the femur, and fifteen and a half shorter than the tjbia. The first metatarsal is a free bone, with a peg-like shaft and exlarged lower extremity. It is enlarged at its proximal end where it sup-.
