The literature concerniug this species of Dolphin dates from 

 184G, when Mr. Brightwell * figured a female taken near Yar- 

 mouth under the name of Delphinus tursio, but which Dr. Gray f 

 immediately afterwards showed to be a species new to science, 

 and named it as now known. Another contributor was Eschriclit |, 

 who described as DelpJiinus Ihsenii what appears either this 

 identical species, or but a variety of it, distinguished by a some- 

 what narrower beak, smaller-sized and more numerous teeth. 

 The venerable Nilsson adopted Eschricht's determination in the 

 ' Scandinavian Fauna.'
