The beak of the skull is more slender, and the teeth more numerous 

 than shown in those of any other species of this genus, yet this dolphin 

 is considered by some writers the same as the Lencopleurus, both 

 being about the same size, bearing a resemblance in the distribution of 

 the colciuring, and inhabiting the same locality.
