described lur H. aurea, the carmine particles were found in the 

 nephrostomial tubes and throughout all the blood-spaces of the 

 kidney and in the Renal and Renal Portal Veins, in which the 

 particles were embedded in the mass of coagulum, but none in 

 the uriniferous tubules or ureter. Apparentlj' the pressure in 

 the Posterinr Vena Cava Avas so great in this instance that the 

 carmine found it ea>ier to spread back into the branches of 

 the Rfual Portal Vein tlian to pass on into the Posterior Vona 

 Cava. 



BUFOXIDAE. 



Pseudflphryne australis. 



The kidneys in this form are much more triangular in trans- 

 verse section than those of Hyla aurea, the outer edge being 

 formed by the ureter ventrally and Renal Portal Vein dorsally. 

 The Renal Veins emerge at the ventral edge of the inner side, 

 while the Renal Arteries enter the kidney just internal or dor>al 

 to the exit uf the Renal Veins, and the Vasa effereutia enter 

 immediately to the outer side of these veins. 



The general arrangement of the uriniferous tubules seems to 

 be as in Hyla aurea, the difference in character between the 

 glandular and conducting parts of the tubules being specially 

 well-marked. The Malpighian bodiei^ are almost spherical and 

 somewhat less numerous than in Hyla aurea. There is but little 

 supportive fibrous tissue, though the blood-spaces are still 

 small and normal in relationship. The nephrostomes are most 

 numerous posterior to the plane of the hinder- end of the 

 Testes, and from the median line of each kidney outwards. 

 Their funnels run more lengthwise and obliquely in the kidney 

 in this form than in the previous forms, so that they are less 

 often cut longitudinally in transverse sections of the kidneys. 

 However, here, as in Hyla aurea and H. lesueurii, they open into 

 the blood-spaces directly connected with the Renal Veins, their 

 internal ends being alway;> surrounded by a mass of blood 

 corpuscles. 



Notaden bennetti. 



The kidneys of this form show the same tendency to adpres- 

 sion of the inner part of their dorsal surfaces as has already 

 been found in PseudophrAiie australii>. Here also the Renal
