Raia batis, Lin. 
A specimen of Grey Skate, measuring sixteen-and-a-quarter inches 
across the pectoral fins, had in its stomach the remains of Crangon 
allmanni, but apparently nothing else. 
Raia fullonica, Lin. 
A specimen of Fuller’s Ray, measuring fifteen-and-a-half inches across 
the pectoral fins, had also been feeding on Crustacea, but the species 
could not be determined. 
Raia radiata, Donovan. 
The stomach of a small Starry Ray was found to contain only the 
remains of fish too imperfect for identification. ' 
The three fishes referred to above, which had been! obtained from a 
trawling steamer working in the North Sea, were examined in March 
1902. 
Squalis acanthias, Lin. 
A considerable number of Picked Dog-fishes have been examined for 
ecto- and ento- parasites, and as their stomachs were also examined, I 
append some observations on the food observed in the stomachs of these 
specimens. The number of specimens referred to here is twenty-two. 
They were captured in the North Sea, and forwarded to the Laboratory 
during the month of March 1902. Hight were examined on the 7th, 
four on the 14th, and ten on the 26th of the month. ©
