DR. J. VON HAAST ON A NEW ZIPHIOID WHALE. 



The first of the accompanying photographs shows the three skulls 

 in comparison with each other; the second the middle portion of the 

 second skull, belonging to an aged (male 1) individual; whilst the 

 following list gives the principal dimensions of these three skulls with 

 the soft parts attached, as far as they could be ascertained ; but as 

 soon as they are macerated I shall offer some further observations on 

 their anatomical structure. 



Table of Measurements of three Skulls of Mesoplodon Grayi, 

 with the greater portion of soft parts adhering. 



I should have liked to give also in this list the breadth of the ros- 

 trum at the anteorbital notches, as it would have supplied another im- 

 portant point for comparison ; but the coverings prevented this ; also 

 I was not able to give the total length of each skull, owing to the oc- 

 cipital portion being cut off; but the length of the skulls from crest 

 of nasals to anterior border of the rostrum, as well as the length of 

 the ramus of each mandible, will supply this deficiency and offer us 

 sufficient material for comparison. 



* The drying of the skin has been so unequal in the different, specimens, and 

 even "on the two sides of the same skull, that the position of the gape cannot be 

 fixed with'precision.
