426 MR. G. A. BOULENGER ON ORIENTAL [Apr. 28, 



distinct ; loreal region very oblique, concave ; nostril a little nearer 

 end of snout than eye ; interorbital space a little broader than 

 upper eyelid ; tympanum hidden or feebly distinct, its diameter 

 g to I that of eye, from which it is sepaiuted by a space less than 

 its own diameter. Fingers obtuse, not swollen at the end, first 

 and second equal or first the longer, third nearly twice as long as 

 second ; subarticular tubercles, if distinct, irregular in their dis- 

 position ; two moderately large carpal tubercles, inner a little 

 larger than outer. Toes short, obtuse, like the fingers, webbed 

 at the base in females, 4 to | webbed in males ; third toe not 

 reaching beyond base of antepenultimate phalanx of fourth ; sub- 

 articular tubercles sometimes distinct, sometimes more or less 

 confluent into an obtuse ridge ; inner metatarsal tubercle small, 

 oval, feebly prominent. Tibio- tarsal articulation reaching the 

 shoulder ; tibia -^ to 4 length from snout to vent ; foot as long as 

 head. Skin smooth or with small tubercles above, granular on 

 belly ; a glandular fold from eye to shoulder. Brown, grey, or 

 pale olive above, with small or large dark brown spots or marblings, 

 which may be irregular or form a symmetrical pattern ; a more 

 or less distinct dark canthal and temporal streak ; sides of snout

The larva has been first noticed by me, from specimens from 

 Sumatra and Perak, and others have since been obtained in 

 Selangor by Mr. Butler, and in Perak by Dr. Hanitsch. These 

 tadpoles are of the same type as the typical Pelobatids of Europe, 

 but remarkable in being marked all over with numerous deep black 

 dots or round spots. ISo observations have been made on the 

 bi'eeding-habits, but it is probable that the eggs are laid in the 

 water, being similar to those of Pelohates. Eggs from the oviducts 

 of a female 65 millim. long measure 2 millim. in diameter. 



Mr. A. L. Butler observes (Journ. Bombay N. H. Soc. xv. 1904, 

 p. 397) that the larval period of existence is very prolonged, and
