Skull JVo. lG2off, in ike collection of the British Museum. 



Among the skulls differing from the ordinary D. delphis in some re- 

 spects is one in the British Museum, No. lQ2oa, labeled 1). longirostris. 

 In this skull the pterygoids are somewhat broader at the free ex- 

 tremity than is nsual, and the breadth at the orbits is considerably less. 

 This skull is 4V'" long, while the breadth at the orbits is but 14"". No. 

 574;«, in the (Cambridge Museum from the Bahamas (see Table, p. 48, No. 

 15), which isone of the skulls having the least width at the orbits, meas- 

 ures 17. C*^'" at this point, though but 47.4'"'" in total length. I am un- 

 able, however, to discover any other characters by which to separate it 

 from D. delphis, and regard it inadvisable, therefore, to reuiove it from 

 that species. 



Delphinus ful co/asciatus Ilombron and Jacquinot. 



The type of D. fulvofasciatus, Hombrou and Jacquinot, No. ^3025, in 

 tlie Paris Museum, from Hobart Town, Tasmania, differs from the ai^cr- 

 age I), delphis, so far as I was able to determine, only in being somewhat 

 broader across the orbits, as is also the case with No. «3071 in the same 

 museum from Tasmania, and labeled D. tasmaniensis. The length of 

 these skulls and the width at the orbits are compared in the following 

 table with the same measurements of a skull also in the Paris Museum, 

 from Algeria, and with No. 20S73 in the U. S. National Museum, from 

 Block Island : 



No. 15, in the table on p. 4S, is of about the saaie proportions as the 

 skull labeled J), tasmamcnsis, but the locality is unknown ; it may bo 

 also from Tasmania. 



We have, however. Professor Flower's statement that he has ex- 

 amined a series of skeletons of (apparently) I), delphis from New Zea- 

 land waters and can find no characters by which to distinguish them 

 from I), delphis from the coast of Europe.
