Carpometacarpus: Greatest length, externally, ; length of process of meta- carpal I, ; depth of distal end from internal tuberosity of metacarpal II through distal metacarpal symphysis, measured on right carpometacarpus, Wing phalanges: Lengths: digit I, phalanx 1, ; digit II, phalanx 1, ; digit II, phalanx 2, ; digit III, phalanx 1, Description.—As exposed on the diatomite slabs and shown in the latex molds, the left side of the skull and sternum and the elements of the left side of the skeleton are best preserved. Although the cranial part of the skull is incompletely preserved, the rounded posterior contour of the supraoccipital and the narrow, sharply ridged temporal fossa are distinguishable. The latex mold (Fig. 3) defines the extent of the short beak, which more closely resembles that of Uria I. lomvia than any of the adult specimens of either U. I. arm or U. aalge at hand. The mandible depth is even greater than in U. I. arra (see Table 1). The position of the furcula is indicated on holotype slab PB7960B by two holes anterior to the coracoids. Filled with latex in preparing the molds, the poorly defined tips appear, but reveal no dependable characters. The sternum is damaged posterior to the coracoidal sulcus, and the area of the costal ridges is pushed forward and folded onto the carina so that from this point to the posterior end the dorsal surface is exposed. Because of this damage, the total length as measured on the specimen (and given above) could be as much as 10 mm less than the actual length of the sternum. The anterior contour of the carina shows clearly in lateral view (Fig. 2) as a broad arch, in contrast to the straight contour dorsal to the forward thrust of the apex typical of the Recent species of Uria.
