4505c (3709), all from Hajula. Of these the first-named is 

 taken as the type, inasmuch as it presents a greater portion 

 of the body than either of the others does. Even in this, the 

 tail is missing and a part of the right side is gone. 



The disk is broad and rounded. The snout is slightly 

 drawn out, but its tip is rounded. The greatest width across 

 the pectorals is 156 mm. The distance from the snout to the 

 hinder border of the pectoral girdle equals 82 mm. ; from the 

 snout to the pelvic girdle, 117 mm. There appear to be 15 

 vertebrae between the pectoral and pelvic girdles. 



The disk is everywhere covered with a very fine shagreen, 

 and no asperities are anywhere visible. On the upper surface 

 of the snout there are a few enlarged scales, each nearly 2 mm. 

 across. On the upper surface, on each side of the midline 

 and over the pectoral girdle, is a patch of scales, some of 

 which are about .5 mm. in diameter. 



On each side of the head, where the scales have been broken 

 away so as to expose the mouth, may be seen a few small 

 teeth. The impressions of the gill arches are faintly seen; 

 likewise those of the eyes and the nasal cavities. 



The other specimens add little or nothing to our knowledge 

 of the species. 



Three other species of Raja have been described from 

 Mount Lebanon. Raja expansa (Davis), from Hakel, has a 

 very broad disk, and the pectoral fins are acute at their outer 

 angles. This species was regarded by Davis as belonging to 

 RhinohaUis (Trans. Roy. Dublin Soc, (2), III, 1887, p. 486, 

 pi. xviii). Raja pHmarmata A. S. Woodward (Cat. Foss. 

 Fishes, I, 1889, p. 85, pi. iv, figs. 1-3), from Sahel Alma, also 

 has the outer angles of the pectorals acute. Raja minor Davis 

 {op. cit., p. 493, pi. xxi, fig. 2), from Sahel Alma, is either a 

 very small species or the young of a species otherwise un- 

 known. The pectorals are rounded. There is little or no 

 shagreen on the disk. The disk is very broad. 



This species is named in honor of Professor R. P. Whit- 

 field, Curator of the Department of Geology of this Museum, 

 who is the author of many important memoirs on palseon- 

 tology, among them one entitled 'Observations on some
