15. Ixalus larutcnsls, Blgr, 
(PL V, Figs, 3 and 4) 
Snout rounded or obtusely pointed, as long as the diameter of the orbit; 
can thus rostralis distinct ; loreal region concave ; nostril a little nearer the 
end of the snout than the eye ; interorbital space as broad as the upper eyelid ; 
tympanum moderately distinct in the adult, indistinct in the young, half the 
diameter of the eye. Fingers free, toes half webbed ; discs of fingers as large 
as the tympanum ; subarticular tubercles moderate ; a small inner metatarsal 
tubercle. The tibio-tarsal articulation reaches between the eye and the tip of 
the snout. Upper parts smooth, or with small fiat warts ; throat, belly, and 
lower surface of thighs granulate. Grey brown or reddish-brown above, with 
dark brown symmetrical markings, a cross-band between the eyes being con¬ 
stant ; usually a )( or )-(-shaped marking on the anterior part of the body; 
sides of body and of thighs with white spots on a brown ground, or between 
a brown network ; a dark-brown lumber spot may be present ; limbs with 
dark cross-bands ; lower parts white, spotted or speckled with brown. One 
of the two young specimens from Jalor has a whitish vertebral line from end 
of snout to vent, a similar line along the upper surface of the thigh and leg 
and another from the chin to the breast ; the lower parts are obscured by 
brown mottlings. 
From snout to vent, 35 mm. 
This species was described in 1900 1 from specimens obtained in the 
Larut Hills, between 4,000 and 4,500 feet altitude. Two young specimens 
from Bukit Besar (2,500 to 3,500 feet) are in Messrs. Annan dale and 
Robinson's collection, and are here figured. 
* The specimens were found among dead leaves, to which they bore a 
remarkable resemblance, on the jungle floor.' 
16. Ixalus horridus, sp, nov. 
(FI. VI, Fig. 2). 
Very similar in general appearance to Rhacophorus leprosus , Schlg., and 
Ft. CQStkalis , Blgr. Head rather strongly depressed, the obtusely pointed snout 
a little longer than the diameter of the orbit; canthus rostralis obtuse; loreal 
region concave; nostrils close to the end of the snout; interorbital space a little 
narrower than the upper eyelid ; tympanum distinct, as large as the eye. 
Fingers half webbed, with large terminal expansions which are broader than 
long, and as broad as the diameter of the tympanum ; toes webbed to the 
disks, which are smaller than those of the fingers ; terminal phalanx bifur¬ 
cate ; subarticular tubercles of fingers and toes very small; a small, oval,
