rower; in the lower lip, the inner series is narrowly interrupted 

 in the middle, the three others are continuous. Body and tail 

 largely spotted and marbled with black; a black streak along 

 the middle of the side in the second half of the tail. 



Head and body 18 millim.; tail 32; width of body 13; depth of 

 tail 12. 



43. Hylambates hyloides, sp. n. (Pi. II. figs. 1-2). 

 Vomerine teeth in two small groups between the choanae. 



Head broader than long; snout rounded, as long as the diameter 

 of the eye; interorbital space as broad as the upper eyelid; tym- 

 panum moderately distinct , about half the diameter of the eye. 

 Fingers moderate, free; toes with a mere rudiment of web; disks 

 of fingers and toes rather large, as much developed as in Hyla 

 arborea; inner metatarsal tubercle strong , compressed , shorter 

 than the inner toe. The tibio-tarsal articulation reaches the tym- 

 panum. Skin finely areolate above , coarsely granulate beneath. 

 Green or brownish olive above, uniform or with dark symmetrical 

 spots or streaks often uniting with a triangular or T - shaped 

 marking between the eyes; constantly a dark streak, light-edged 

 above, from the end of the snout along the canthus rostralis and 

 above the tympanum to the side of the body, where it may 

 break up into small spots; limbs sometimes with dark cross-bars. 

 Male with a moderately developed subgular vocal sac. 

 From snout to vent 48 millim. 



Numerous specimens from Bolama, Portuguese Guinea. 



This species, which in form and colour closely resembles our 

 European Tree-frog, is easily distinguished from the preceding by 

 the much larger digital disks. 



Prof. Barboza du Bocage has recorded (J. Sc. Lisb. [2] n.^ XIV. 

 1896. p. 81) two species from Bolama: H. viridis , Gthr. , and 

 H, cmnamomeus , Boc. The British Museum having received 

 from the Lisbon Museum a specimen from Bolama under the 

 name of H, cinnamomeus , which is identical with H. viridis, 

 it is probable that Bocage's H. viridis , is the species here de- 

 scribed as new. 



44. Hylambates leonardi, sp. n. (Pi. II. fig. 3). 



Vomerine teeth in two small groups just behind the level of 

 the choanae. Head slightly broader than long; snout rounded, as 

 long as the diameter of the eye; interorbital space as broad as
