We have synonymized _Graculavus pumilis_ Marsh, 1872, with _Telmatornis priscus_ Marsh, 1870, and discuss below the characters by which _Graculavus_ (restricted to _G. velox_) may be separated from _Telmatornis_. Shufeldt (1915) has already presented adequate evidence that _Graculavus_ is not a cormorant and is instead a charadriiform. The following combination of characters of the proximal end of the humerus is shared by _Graculavus_ and _Presbyornis_ and distinguishes these genera from other Charadriiformes: (1) lack of a distinct lanceolate scar for M. coracobrachialis cranialis; (2) lack of a distinctly excavated second (dorsal) tricipital fossa; (3) presence of a distinct tumescence in the proximoventral portion of the tricipital fossa; scars for (4) M. scapulohumeralis caudalis and (5) M. scapulohumeralis cranialis very large and distinct; (6) attachment of M. latissimus dorsi cranialis a well-defined, raised protuberance situated dorsal to the median ridge of the shaft; (7) tuberculum dorsale well defined, distinctly pointed. In most of the preceding characters that it preserves, the single proximal end of humerus referred to _Telmatornis_ (the holotype of _G. pumilis_) agrees with _Graculavus_ and _Presbyornis_. Among living families, the Burhinidae are the most similar to _Graculavus_; both agree in characters 1, 2, 4, and 7, with certain species of _Burhinus_ also having characters 3 and 6 present but less developed. _Graculavus_ differs from Burhinus mainly in having (8) the head not as deep and bulbous; (9) distance from head to tuberculum dorsale greater; (10) tuberculum dorsale smaller, much less projecting; (11) tuberculum ventrale in ventral view more elongate; and (12) scar on tuberculum ventrale for M. coracobrachialis caudalis much larger and more distinct. _Graculavus_ is very similar to _Presbyornis_, agreeing with that genus in characters 8 and 10 but differing in characters 11 and 12 and in (13) having the head more deeply undercut. _Presbyornis_ is intermediate between _Graculavus_ and the _Burhinidae_ in character 9. _Graculavus velox_ was a fairly large bird, being approximately the size of _Presbyornis_ cf. _pervetus_ and somewhat larger than the large living burhinid _Esacus magnirostris_. =Graculavus velox?= Figure 9_d_ Referred Material.--Abraded right carpometacarpus consisting mainly of the major metacarpal, NJSM 11854.
