124 MR. T. SOUTHWELL ON THE WHITE BEAKED DOLPHIN. 
coast. To the West of England, Eonaghadee on the Irish coast 
is the only spring station known. The return migration extends 
from late in August to the middle of October, when they pass 
southward through the North Sea, probably again attracted by the 
Herrings at that time so abundant. 
One abnormal occurrence wdiich took place in the month of 
December, at tlie mouth of the river Dee, is recorded in the 
‘ Annals and Magazine of Natural History’ for April, 1863. All 
the other instances of which I have exact particulars, have occurred 
in the spring or autumn months named. Of the eighteen British 
specimens, "with regard to whicli I have precise information, four 
have occurred in March, one in April, one in May, one in July, 
four in August, three in September, two in October, one in the 
“ Autumn,” and one in December. 
Of the continental specimens, I have not sufficient information 
to generalize upon. Van Benedcn gives the dates of the two 
Ostend specimens, as one in July, 1851, and the other “ an milieu 
de I’hiver de 1852.” It would be interesting to know the dates of 
the Kiel and Skanbr specimens, ■which probably became entangled 
either on their northward or return journey in the shoals and 
intricate channels of the Danish Islands. The date of the 
Gullholmen specimen is interesting, as it throws light upon the 
season of reproduction, -which probably takes place in the early 
autumn ; in further support of which I may mention the newly- 
born young one, which I myself saw brought into Yarmouth, on 
10th September, 1881. 
The food of this species is doubtless the same as that of the Dolphin 
and Porpoise. In two instances where I examined the contents 
of the stomach, I found it to consist of Herrings and Whiting. 
On the Norfolk coast this sjiecies is certainly known by the 
name of “ Scoulter,” but whether any other species shares that 
name Avith it, I cannot say, I suspect, however, D. tursio is also 
so knoAvn. D. del phis has never come under my observation on the 
Norfolk coast, but I strongly suspect it is knoAvn at sea to the hshcr- 
mcn under the name of “ Bottle-nose Dolphin,” and that the name 
of “Scoulter” is shared alike by D. iursiu and L. cdhiroslris. It 
is so difficult, hoAvcver, to determine the species of a Cetacean 
from the vague descriptions the fishermen give, that I desire to 
make these remarks Avith due caution.
