738 AFRICAN KEI'TILES AND BATRACHIANS STEJNEGER. 



Ill tlie first place the rudiments of webs between the fingers are 

 very minute; the temporo-crural fold as well as tlie j;ular fold and the 

 one surrounding- the ventral disk strongly marked; skin on the disk 

 as well as on the space between the lateral folds coarsely granular, 

 skin on throat and underside of thighs more finely so. 



Color above (in aUniliol) very light diab with minute brownish spots 

 on lower back; a well defined arrow-shaped brownish gray mark be- 

 tween eyes, the point turned backwards and a short shaft-like projec- 

 tion from the anterior margin; a similaily colored band from nostril 

 through eye obliquely down to corner of mouth; lips white, with an in- 

 distinct broad brownish band from eye to lip; a dusky line across the 

 wrist and a similar one across the middle of the forearm, the si)ace 

 between being perceptibly lighter than the ground color; lower half of 

 tibije apparently similarly marked; lower surface of limbs, breast be- 

 tween the gular fold and the anterior border of the ventral fold, as 

 well as space between the lateral border of the latter and the temporo- 

 crural fold, cinnamon colored. 



Phrynobatrachus acridoides (Cope). 



Two s])ecimens (U. S. National Museum, Nos. 20101-20102), collected 

 by Mr. Chanler on the Tana River, agree in all essential points with 

 Cope's original description (Journ. Acad. Phila., vi, 18G7, p. 198) of 

 Staurois acridoides. In addition to the characteristic dorsal i)lica} our 

 specimens have another descending from beneath the well-pronounced 

 tympanum to the humerus. The coloration is also as described, though 

 our specimens have no vertebral baud, but there is a large blackish, 

 pale-margined, triangular patch across the top of the head to the outer 

 edge of the eyelids, the apex (►f the triangle pointing backwards; the 

 tympanum is covered with a dark patch and the upper lip is dark with 

 minute white dots. 



Rana mascareiiieusis Dim. & Bibr. 



Five specimens (U. S. National Museum, Nos. 1()734-10738) from the 

 Seychelles by Dr. Abbott. In all the specimens the fifth toe is longer 

 than the third, or exceptionally equal to it, but never shorter. No. 

 IfiT.')") is a male with the external slits of the vocal vescicles parallel 

 with the commissure and situated directly under the tympanum. 



APOD A. 



Hypogeophis rostratus (Cuv.). 



Six well-preserved specimens, five adult and one young ( U. S. Jilational 

 Museum, Nos. 20440-2044.")), collected by Dr. Abbott in the Seychelles, 

 and one half-grown si)ccimon leceived from the Paris Museum (Xo. 

 20403), throw considerable light on the individual variation of the 

 present species and the validity of the characters assigned to it.
