This species differs so much from the other members of the 

 genus Hyhdes in the extensive web between the toes that it might 

 be made the type of a new genus. I am, however, unwilling to 

 adopt such a course at present, in view- of tlie existence of the 

 species H. pahnatus and i/. raniformis, which afford a link between 

 this and the more typical forms, and render the character of the 

 development of the web between the toes one of very doubtful 

 value in this group ; a conclusion which is further strengthened 

 by a study of several other genera of Tailless Batrachians.

 Paramba and Chimbo. 



11. Htlodes longieosthis, sp. n. (Plate XA^. fig. 1.) 



Tongue oval, slightly nicked behind. A'^omerine teeth in two 

 strong trans\erse series close together behind the choanae, on a 

 level with the palatine bones. Head longer than broad ; snout 

 obtusely acuminate, much longer than the diameter of the orbit ; 

 canthus rostralis strong ; loreal region moderately oblique, concave ; 

 nostril much nearer the tip of the snout than the eye; interorbital 

 space as broad as the upper eyelid ; tympanum very distinct, half 

 the diameter of the eye. Fingers moderate, first extending as far 

 as second : toes moderate, one third webbed ; tips of fingers and 

 toes dilated into well-developed disks, which are a little broader 

 than long, and measure about one third the diameter of the eye ; 

 subarticular tubercles strong ; a small oval inner and a rounded 

 outer metatarsal tubercle. The tibio-tarsal articulation reaches a 

 little beyond the tip of the snout. Skin smooth above and below, 

 or wdth a few very small warts on the head and back ; a strong 

 fold above the tympanum ; a well-marked ventral disk. Grey- 

 brown or pinkish above, with a dark cross-band between the e^'es, 

 and a more or less distinct dark hourglass-shaped marldng on the 

 back ; a black canthal and temporal streak : limbs Avith regular 

 dark cross-bars ; hinder side of thighs uniform brown ; white 

 beneath, with a few dark broAvn spots on the throat and bi'east. 

 Male with an internal vocal sac.

Several specimens from Cachabe.

Tongue oval, slightly nicked behind. Vomerine teeth in two 

 short oblique series behind the choanse. Head moderate, as long 

 as broad ; snout rounded, as long as the diameter of the orbit ; 

 canthus rostralis distinct; loreal region oblique, concave ; nostril
