8. MiCROHYLA ACHATINA, Boic. M. 



9. MiCROHYLA INORNATA, Sp. U. M. 



Snout obtuse, shorter than the diameter of the orbit ; interorbital 

 space a httle broader than the upper eyelid. First finger much shorter 

 than second ; toes moderately elongate, quite free ; tips of fingers 

 and toes dilated into very small disks ; subarticular tubercles very 

 distinct ; inner metatarsal tubercle very small, round ; no outer 

 tubercle. The tibio-tarsal articulation reaches the eye. Back 

 covered with small smooth warts. Dark brown above, spotted or 

 marbled with black; sides of head black, with a series of white spots 

 along the upper Hp ; lower parts brown ; throat of male black. 

 Male with a subgular vocal sac. 



From suout to vent 20 millim. 



Three specimens, two males and one female. 



10. Phrynella pulchra, Blgr. M. 



Two male specimens, agreeing with the types from Malacca. The 

 specimen from the mountains of Perak, referred to this species 

 by Giiuther (Ann. & Mag. N. H. (5) xx. 1887, p. 313, pi. xvi. 

 fig. B), is a distinct species, which I will call P. pollicaris on account 

 of the strong tubercle-like rudiment of pollex which is developed in 

 the male of this species but not of P. pulchra. Other differences 

 are found in the stouter habit, the shorter head, the presence of a 

 strong transverse fold connecting the posterior borders of the eyelid, 

 the shorter and thicker digits with much stronger subarticular 

 tubercles, and the hardly half-webbed toes. The coloration is also 

 a much plainer one. 



11. BuFO melanostictus, Schn. M., I. 



12. BuFO quadriporcatus, Blgr, M. 



13. BuFO PARVUS, Blgr. M., I. 



14. BuFO ASPER, Gravenh. M., I. 



1 5. Leptobrachium hasseltii, Tsch. I. 



A larval specimen with well-developed limbs, obtained by Mr. 

 Iversen, enables me to name several tadpoles of rather large size, 

 from Larut, Perak, presented to the Museum in 1886 by Dr. J. 

 Anderson. These are remarkable in being marked all over with 

 numerous deep black dots. Spiraculum sinistral, equally distant 

 from the end of the snout and from the tail ; latter once and a half 

 as long as the body. Length of body 25 millim. 



16. Megalophrys nasuta, Schleg. M.
