 translated by Dr. Haslam*. There is a fuller account of the- 

 lymph-sacs of the Common Frog in the more recent edition of 

 Gaupp. I figure hei-e (text-fig. 185) for purposes of comparison 

 with Hemisus the saccus iliacus in the large female of Rana 

 gupjvjl. It is a much more elonga.ted " sac in proportion to its 

 breadth than is the case with that of R. esculenia, as displayed 

 in the figure cited from Dr. Haslam. Its walls also are-

 of the chordfe tendineae of the valves of the mammalian heart. 

 There are two of these branched stays between the dorsal 

 and ventral walls of the sac. Gaupp mentions these structurea 

 as occurring in the lymph-sacs of Rana, but does not parti- 

 cularize their existence in the saccus iliacus. They are not 

 represented in the figure, to which I have referred, of the sao 

 in Rana esculenta. This sac communicates by a wide orifice
