session of a diminutive rod-like vomer — points which are, I should 

 say, of no more than specific value, the last possibly but evidence 

 of the greater intactness of the specimen after maceration ; for, 

 as I have noted, Eyton shows the existence of a vomer in 31. bra- 

 siliensis. I may take cognizance of the presence of a large ossified 

 sclerotic, which in Momotus [Baryphthengus] ruficapiUas, as in 

 Eumomota sujierciliaris, I have found thin and delicate. 



As to sternum and shoulder-girdle, the notches are converted 

 into foramina, as in Momotus and Eumomota, and they are of 

 a size intermediate between these two forms. The extreme 

 length of the breast-bone from the rostrum backwards is 1*4; 

 greatest width posteriorly 1"1 inch. The coracoid is 1*1 inch 

 long, the oblique sternal diameter shorter by 0"1 inch. In this 

 respect it stands midway between the two genera compared, but 

 with proclivity towards Eumomota. 



Excepting in dimensions, the pelvis has no feature peculiarly 

 its own. Its characters, as that of Eumomota, are shortness, pos- 

 terior breadth and flatness of the dorsum. The prseacetabular 

 and postacetabular areas are subequal in length. The width of the 

 latter is much greater than its length. The fore ilia lie widely 

 out, and with little obliquity of tilt. There is only an indication 

 of shelving of the horizontal ridge dividing postilium from 

 ischium. The tuberosity, the spine, and the ischiatic space are 

 alike short, the former, however, being widish. The inner ante- 

 rior iliac borders do not meet the neural spine and convert the 

 muscular spaces into foramina, as is the case in the Touracous. 



Pelvic dimensions: — extreme length 1"2; greatest width (at 

 ischia) 1 inch. 



The humerus is stout, of moderate size, and the shaft is bent 

 upon its long axis outwardly in the upper and backwardly in 

 the lower half. The radius has a thick ish shaft in i-elation 

 to that of the ulna. In pattern the metacarpus is identical with 

 that figured of Eumomota (figs. 26-31), but a little larger. 

 There is a well-marked and roughened process above, where the 

 thumb articulates, and in approximation to the first carpal bone 

 during extension of the wing. The second outer moiety of the 

 metacarpus is laterally flattened, rough, and it appears to be 

 that portion of the united bone which descends lowest.
