teeth are small and curved, and vary in number from 23 to 25 on 
each side of both jaws. This species, like the last-named, is easily 
distinguished by its colour, which is deep purplish black above ; 
while the nose and a well-defined line along the upper jaw, as well 
as the whole of the lower jaw and belly, are cream-colour, varied 
in parts with chalk-white, which contrasts finely wtih the deep 
black colour of the back. This Dolphin also inhabits the North 
Atlantic, but does not appear to be common. Only three or four 
specimens have been met with on the east coast of England. 
It is not a little remarkable that the number of species of Whales 
and Dolphins which have been ascertained to have occurred on 
the coasts of Great Britain and Ireland is in excess of what has 
been recorded for the European Continent. This, no doubt, is 
owing to the fact of their remains having been more carefully 
collected and identified, and more attention given to the study of 
these animals by English than by continental naturalists. 
The late Dr. Gray, who made a special study of the order 
Cetacea, published several articles on the species frequenting 
or occurring in the British Islands, to which the reader should 
refer. In ‘The Annals and Magazine of Natural History’ for 
1846 (vol. xvii, p.82), he gave a list of the British Cetacea 
containing seventeen species which he had the opportunity 
of personally examining, either entire or in osteological fragments 
sufficient to enable him to determine them. In the ‘ Proceedings 
of the Zoological Society’ for 1847 (p. 117), he printed some 
additional observations on the subject; and in the volume of 
‘Proceedings’ of the same Society for 1864, he published a paper 
“On the Cetacea which have been observed in the Seas surrounding 
the British Islands,” in which he attempted to condense all the 
original matter in the various antecedently published works on 
the British Whales and Dolphins, and gave the results of his 
examination of all the specimens he could collect. This paper 
is illustrated with figures of the more characteristic bones. In 
‘The Zoologist’ for 1873 (pp. 3357—8364 and 3421—3433) he 
published a “Catalogue of the Whales and Dolphins inhabiting 
or incidentally visiting the Seas surrounding the British Islands.” 
To all of these articles, as well as to the more recent papers and 
monographs by Prof. Flower in the ‘ Proceedings’ and ‘ Transactions’ 
of the Zoological Society, the reader would do well to refer. Nor
