1876.] DR. J. VON HAAST ON A NEW ZIPHIOID -WHALE. 



The first of the accompanying photographs shows the three slvulls 

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

 second skull, belonging to an aged (male?) 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 o/Mesoplodon Grayi, 

 with the greater portion of soft parts adhering. 



Height of Skull from top of nasals 

 (skin preserved) to lower border of 

 pterygoids, the latter lying exposed . . 



Greatest breadth of skull across post 

 orbital processes of f rentals 



Length of skull from crest of nasal bones 

 to anterior border of rostrum, in 

 straight line 



Length of ramus of lower jaw, soft parts 

 preserved on anterior border 



From gape* of mouth to anterior bor- 

 der of lower jaw 



From anterior border of lower jaw to 

 centre of toolh 



From centre of tooth to gape of mouth. 



Breadth of lower jaw at centre of 

 tooth 



Distance from extremity of rostrum to 

 first anterior tooth 



Distance from gape to end of teeth 



Eye, perpendicular diameter, about 



Opening of blower, the two extremities 

 slightly directed backwards, about

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

 trum at tlie 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 diflferent specimens, and 

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

 fixed with precision.
