sides. Choaupe jalaced well forward, with a groove entering 

 anteriorly from the side. Palatine ridges not present.* Two 

 dermal ridges in front of the (esophagus; the anterior is some- 

 times not papillose, being represented by a median dermal lobe, 

 the posterior long and always papillose. Arms rather weak. 

 Fingers subcylindi-ical or depressed, not fringed or disked, the 

 first a little shorter than the second. Hind limb stout. Foot 

 broad. Toes moderate or rather short, subcylindrical or de- 

 pressed, not fringed or disked. A weak indication of an inner 

 metatarsal tubercle, otherwise the palmar and plantar surfaces 

 are smooth. The length of the outstretched hindlimb, from the 

 anus to the tibio-tarsal articulation, equals the distance from the 

 anus to the axilla. Skin perfectly smooth. 



Colour (in spirits) uniform dark brown above. Lower 

 surfaces also uniform dark brown, or creamy-white, variously 

 clouded and speckled with dark brown (PL liv., fig. 2). Anterior 

 part of forearm sometimes yellowisli. Lower eyelid white. 



Total length of type from snout to vent, 27 mm. 



i/oc— Six specimens, from Mount Scratchley, on the Owen 

 Stanley Range, British New Guinea, at an altitude of 12,200 ft. 

 Collected by the late A. Giulianetti in September and October, 

 1896. The largest specimen, figured on Plate liv., fig. 1, has been 

 chosen as the type. 



Type in the Australian Museum, Sydney. 



The ligament mentioned in the above diagnosis of the genus 

 Aphantophryne is made clear by reference to the Plates. The 

 question must necessarily arise as to whether this ligament repre- 

 sents a stage in the process of the degeneration of the procoracoid 

 cartilage. If we trace the reduction of clavicles and procoracoids 

 through the many phases exhibited by the recent genera, several 

 facts in turn become evident. 



i. As the clavicle weakens (as, say, in Chaperina) the proco- 



* The palatine bones are seen, through the transparency of the integu- 

 ment of the palate, to meet in the middle line, and form a slight expan- 

 sion. This is shown in fig. 1'* on Plate liv., and is also the case in Meto- 

 postira and Hylophorhus.
