 SOUTHERN INDIA AND CEYLON. 



By G. A. BOULENGER, f.r.s., v.p.z.s. 

 With a Plate. 

 (Read before the Bombay Natural History Society 

 on 5lh November 1903.) 

 Rana aurantiaca. 

 Vomerine teeth in two oblique series between the choanpe. Head 

 depressed, longer than broad ; snout obtusely pointed, a little longer 

 than the orbit ; canthus rostralis distinct ; loreal region nearly vertical, 

 concave ; interorbital space a little broader than the upper eyelid ; 

 tympanum very distinct, three-fourths the diameter of the eye. Fingers 

 rather slender, first extending slightly beyond second ; toes' two-thirds 

 webbed ; tips of fingers and toes dilated into small but very distinct 

 disks ; two small metatarsal tubercles. The tibio-tarsal articulation reaches 

 between the eye and the tip of the snout. Skin smooth ; a narrow 

 glandular dorso-lateral fold. Orange above, without spots on the back 

 or bars on the limbs ; a black lateral band on each side of the head 

 and body ; upper lip, canthus rostralis, and dorso-lateral fold white ; 

 terminal disks of toes black ; lower parts white. 

 From snout to vent 38 millim. 



A single specimen of this pretty frog, allied to R. temporalis, Gthr., 

 was found on a bush near Trivandrum, Travancoro, by Mr. H. S. 

 Ferguson. A coloured cast of the frog was made by Mr. Ferguson, 

 whilst the specimen itself, rather poorly preserved in spirit, has been 

 kindly presented by him to the British Museum. 



RlIACOrHORUS PLEUROTiENIA. 



Vomerine teeth in two very small groups close together between 

 the choanal. Snout rounded, a little shorter than the diameter of the 

 orbit ; canthus rostralis obtuse ; loreal region slightly concave ; nostril 

 nearer the end of the snout than the eye ; interorbital space broader 

 than the upper eyelid ; tympanum moderately distinct, not quite half 

 the diameter of the eye. Fingers with a slight rudiment of web ; toes 

 half- webbed, the web very short between the inner toes ; disks a little 

 smaller than the tympanum. The tibio-tarsal articulation reaches the 

 posterior border of the eye. Upper parts with fine vermicular rugosities ; 

 belly and lower surface of thighs with large flat granules. Brown
