Abstract: In September 1990, I collected three bird specimens from the Early Cretaceous of Liaoning, China. Among them, the best one (V 9769) has been published and named Cathayornis yandica (Zhou et al., 1992); the second (V 9941), with only a sternum impression, has not been referred to any known taxa yet; and the third (V9770), an incompletely articulated individual, is significantly different from either Cathayornis and Chaoyangia (Hou et Zhang, 1993) from the same site or any other known Early Cretaceous birds. The third specimen is described here as a new genus and species: Boluochia zhengi, and further referred to Enantiornithes as at least four enantiornithine synapomorphies can be recognized in this specimen: (1) intercondylar fossa of tibiotarsus narrow, medial condyle of tibiotarsus with fairly flat anterior margin in distal view; (2) metatarsus IV reduced; (3) slender lateral process of sternum with expanded distal end; and (4) presence of a peculiar dorsal process on proximal ischium. Boluochia is believed to be a new enantiornithine bird from the Early Cretaceous of China, since Cathayornis from the same site had previously been proposed to be included in Enantiornithes (Zhou, in press). Boluochia is distinguished from Cathayornis in many respects, such as (l) skull with hooked bill; (2) presence of a concave surface between main body and nasal process of premaxilla; (3) lateral process of sternum only slightly expanded distally; (4) trochanter of femur relatively developed; and (5) trochleas for digits 2—4 close in height. Finally, comparisons between Boluochia and extant birds in the skull and hindlimb structures also indicate that Boluochia is probably a bird with not only strong perching capability but also somewhat raptorial habit, although the primitiveness of many of its structures rules out the possibility of its being a raptorial bird in strict modern sense.
