280 .M.\ssr>. T. Southwell a-vl S. F. II;\rmcr on a 



n-lative shortness of the jaws as compared with the adult. 

 The Ziphioid elongation of the beak had not yet been acquired, 

 and no trace of teeth could be detected in either jaw. 



The colour of the foetus was black above and red below, 

 the latter colour being due to the effusion of blood into the 

 skin, which was doubtless white when the foetus was removed 

 irom the uterus. Parts of the head, including a horizontal 

 streak passing through the e^'C, were bluish grey, and the 

 first two inches of both the upper and lower jaws were black.
