2. Leptodactyltts caliginosus, G. Reddish brown, with indistinct blackish 

 maculae on the back, more conspicuous on the hind legs ; a large subcordiform 

 occipital macula. A post-ocular vitta extending a little behind the tympanum. 

 Vomerine teeth in regular curves. Tongue subelliptical, elongated, slightly 

 notched at both extremities. Toes provided with a rudimentary membrane at 

 their base and margined by a membranous fold. Skin smooth in the adult, traces 

 of longitudinal folds in the young. 



Obs. Differs from the preceding species chiefly in the disposition of the 

 vomerine teeth. 



Locality. Rio de Janeiro, Brazil. 



3. Cystignathus parvulus, G. Yellowish brown above, with a deep chest- 

 nut narrow band extending from the tip of the snout to beyond the middle of the 

 length of the body. Beneath unicolor. Head subtriangular, wedge-shaped. An- 

 terior part of the snout depressed and regularly inclined towards the margin of 

 the upper jaw. Legs quite slender. 



Locality. Rio de Janeiro, Brazil. 



4. Cystignathus nebulosus, G. Above, light brown, white and clouded 

 "vrith reddish brown ; a large subtriangular, occipital, deep brown patch. A 

 post-ocular vitta of the same color. Hind legs barred with reddish brown. Be- 

 neath unicolor, whitish anteriorly, reddish posteriorly. Vomerine teeth in two 

 elongated groups, obliquely situated between the inner nostrils ; latter propor- 

 tionally large. Tympanum not visible exteriorly. Eustachian tubes very minute. 

 No lumbar glands. Fingers and toes depressed, latter margined wilh a mem- 

 branous fold, otherwise smooth. Two metatarsal tubercles. Tarsus with a 

 ridge along its inner margin. Skin minutely granular. 



Locality. Valparaiso, Chili. 



5. Crinia (Ranidella) signifera, G. Skin above subtuberculous, beneath 

 glandulous. A spear-shaped blotch on the head. A broad dorsal, deep brown 

 band, forked anteriorly to receive the point of the cephalic spear-shaped blotch. 

 On each side of the latter a greyish or yellowish grey narrow band, beneath 

 which is another, still narrower, blackish brown band. Sides of abdomen and 

 belly marmorated. 



Locality. New Holland. 



Hyl^. 



Ranoidea, Tsch. Vomerine teeth disposed in two groups situated between the 

 inner nostrils. Tongue large, subcircular or elliptical, slightly notched poste- 

 riorly, and free for about one-third or less of its length. Tympanum distinct. 

 Eustachian tubes of considerable development. Fingers and toes depressed, 

 terminated by subelliptical disks, comparatively small. Fingers perfectly free ; 

 toes webbed to a considerable degree. A vocal subgular bladder in the male. 



Obs. The characters of this genus when compared to those oi Hijla, may appear 

 negative. The general physiognomy, which is more ranoid than hyloid, and 

 the smallnessof the subdigital disks, are the two most prominent features of this 

 group. The addition of two species partaking of the characters of the one, unique 

 when the genus was made, will add to the importance of retaining it in the erpe- 

 tological system. If habits go for any thing in the distinction of genera, 

 the fact that Kanoidea are more frequently seen about the waters than on the 

 trees, would certainly have a weight upon the question. 



6. Ranoidea resplendens, G. Deep green above, maculated and streaked 

 with gold. Head depressed, elongated. Tongue of medium size, notched and 

 free posteriorly. Vomerine teeth in two transversely elongated groups, situated 

 between the inner nostrils ; latter semicircular, large. Openings of the Eustachian 

 tubes as large as the inner nostrils. Tympanum very distinct, large, elliptical. 

 Fingers free. Toes webbed up to the digital disks ; membrane emarginate. 



Locality. Wollongong Illawara, near the coast. 



7. IIanoidea flavoviridis, G. Above green, with a black line along the can-
