MR. W. K. PARKER OK THE STRUCTURE AND 
developed. So also is the annular growth of the nasal wall ( n.w .), and the 
appendages ( ii.ld.u.l 3 .) that finish the nostrils ( e.n .). 
The inner nostrils (fig. 8, i.n.) are very large, short oval, and almost transverse ; 
they turn a little forwards, within. 
The palato-suspensorials are well developed, the fore part wide, with a slight pre¬ 
palatine projection; the foot-like pedicle ( pd .) projects well inwards, and the quadrate 
condyle projects well outwards, reaches back behind the stapes {st.), and is large and 
reniform, with a post-condylar lobe; there is no ossification beyond the setting on of 
the quadrato-jugal (qj.). 
The palatines and pterygoids ( pa ., pg.) are quite normal, but remain ungrafted. 
The Eustachian passages (eu.) are only half the size of the inner nostrils, and are 
reniform. The mandible (fig. 9) is perfectly normal; it is rather high. The annulus 
( a.ty .) is large and perfect. The stapes (fig. 11, st.) is oval, emarginate in front, and 
has a boss. The interstapedial (i.st.) is nearly as large, is gently notched below, and 
its fore third is ossified. The medio-stapedial ( m.st .) is a strong phalangiform bar, 
and ends in a perfectly normal spatulate extra-stapedial, with a cartilaginous supra- 
stapedial, confluent above (e.st., s.st.). The stylo-hyal is also confluent above, and the 
hyo-branchial apparatus (fig. 10) is perfectly Ranine. The investing bones are also 
quite Ranine, but the fronto-parietals ( f.p.) are very narrow in front, and fail to cover 
the fontanelle perfectly; they are like those of Pyxiceplialus rufescens, but do not 
unite, behind. The nasals (n. ) are normal, but wide apart; all the marginal bones 
are normal, but the squamosal (sq.) has an exceedingly long postorbital process. 
There are no septo-maxillaries; the parasphenoid ( pa.s .) is exactly like that of a Rana, 
but the vomers (v.) are not; they are sub-quadrate, with short snags. Each bone 
touches the septum nasi, the spike in front of the inner nasal opening is suppressed, 
the front part ends in a spike, and the post-narial spike is short. The dentigerous 
elevations are large, oval, and oblique. 
This Frog differs from its narrow-backed relations, with forked tongues, in having:—- 
1. The whole skull feebly ossified. 
2. The interorbital region very narrow in front. 
3. The main fontanelle left partly uncovered by the roof-bones. 
4. The four bones of the hind skull small, and the girdle-bone imperfect above. 
5. No septo-maxillaries. 
6. The squamosal very long in its post-orbital region. 
7. The stylo-hyals and supra-stapedials confluent, above. 
Second genus. Pelodytes. 
28. Pelodytes punctatus.-— Adult male ; 1^ inch long. Europe. 
The skull of this species is short, the breadth being to the length as 11 to 10; yet 
it looks shorter than it is, on account of the great breadth of the nasal region. In
