DELPHINUS DELPHIS.

D. Moorel are ideulical with those ot 1). delphis. In the following tabic 

 the oieasarenieuts of D. Moorei are placed, by the side of those derived 

 from the No Man's Laud specimen of the same sex ( 9 ) already referred 



to (p. 53) : 



The agreement here is very close. The measurements of £>. Wallcen, 

 Avhi<;li 1 did not see, are stated by Gray to be "nearly the same as in 

 D. Moorei.'''' We have, therefore, two dolphins agreeing with T). dcJphis 

 iu their skulls and proportious, but represented as differently cohered. 

 I believe that they should be looked upon as individuals of that species, 

 inaccurately represented, or at the most as varieties of that species. 



Delpliinus algeriensis Loche.* 



Professor Fischer regards this species as possibly belonging to P. 

 marginatus, but in the coloration, which alone is described, it appears 

 to me to most resemble I), delphis. It is larger than any of the speci- 

 mens of which Professor Fischer has given the dimensions, but is 

 equaled by Scammon's specimens of D. Bairdii [~D. delphis). 



BelpM^ius alhimanus Peale.f 



There is in the National Museum a mounted skin, in a bad state of 

 preservation and without a trace of the original coloration, which is re- 

 corded as the type of this species. It does not closely resemble Peale's 

 figure of the species. Upon cutting open the head, I found only a por- 

 tion of the mandible in position. This and the bones of the mauus, 

 which I also exposed by cutting away the skin, agree with those of D. 

 delphis. We may, I think, faii'ly conclude that Peale's species repre- 

 sents one of the varieties of D. delphis, like D. forsferi, which have 

 areas of white on the fins. The type was from .
