SECOND SUPPLEMENT. 
PART IIL. 
Dipuncuuus, Peale. 
Strigirostris, Jardine. 
Cranium much indented at the base of the bill. Nostrils lengthened. Ovate 
cranium, flattened on the vertex; rounded behind; foramen-magnum large. 
Bill much arched. Inferior maxillary bone much elongated backwards beyond its 
articulation with the os quadratum. Inter obital foramen large. 
Sternum indented with a very large fissure, which extends more than half the 
length of the sternum, and is bounded by a narrow strip of bone, expanded at its ex- 
tremity, and terminating at about half the length of the fissure; the posterior margin 
rounded, and narrower than the anterior. In the young bird I suspect it is penetrated 
with a smaller foramen on each side,.as my specimen has traces of them. 
Ixeel very deep anteriorly ; the lower edge rounded, the front edges curved. 
Pelvis very broad, much like the ground pigeon’s, 
Ribs broad, flattened styliform process, much turned upwards. 
Furculum rounded, but slightly flattened at its articulation with the coracoids. 
Coracoids strong. 
Scopula arched, expanded near the extremities and pointed at the extremities. 
Wingbones of moderate length; the ulna much longer than the humerus. 
Legbones with the metatarsi very short 
Vertebral column strong 
REMARKS.—This curious bird strongly resembles the ground pigeons in the form of the head, 
sternum, and pelvis. It is figured in Owen’s Memoir on the Dodo.
