thing like it before. Mr. F. King, of Grimsby, who sent this 
fish to Bradford, states that it was caught five miles to the 
north-east of the Dogger Bank on December toth, 1906. The 
local evening papers of the 17th December stated that it had 
the head of a Salmon, the body of a Porpoise, and the tail of a 
Shark (!!), so that it attracted considerable attention. I found 
it to be one of the larger species of the Scombrid@ (Mackerels), 
and with the aid of ‘Our Country’s Fishes,’ was able to identify 
it with certainty as the Short-finned Tunny (Ovcynus thynnus). 
Although the Tunnies are common further south, and are a 
source of much economic value as food in the south-west of 
Europe and on the shores of the Mediterranean, yet they are of 
sufficient rarity in the British seas as to merit the following 
description of the present specimen :— 
Colour and Scales.—Back, dark blue, shading to netted grey 
on the sides, and to silvery white below. The scales above the 
pectoral fins larger and forming a corslet, from which smaller 
scales extended towards the tail. Otherwise almost scaleless. 
Measurements, etc.—The total length from the snout to the 
centre, or root, of the tail (measured along the back) was 3 feet 
gt inches. The tail, which was keeled at the sides, was large 
and deeply forked ; the span from tip to tip of the lobes being 
134 inches. The first dorsal fin contained 14 spines (the last 
one very small), and almost joined the second dorsal fin, which, 
although damaged, still showed its triangular shape. There 
were ten finlets behind, one being very small. The pectoral fins 
(which fitted into grooves), did not reach to within about 4 inches 
of the parallel of the second dorsal fin, and measured g and 
7 inches respectively along the upper and lower edges, and were 
edged with white on the inner lower margins. Ventral fins, 
almost joining, not more than an eighth of an inch apart. 
Eight finlets underneath, between the anal fin and tail. The 
greatest girth would be about 30 inches ; it was very solid and 
fleshy and J was assured by the owner that this fish scaled 
nearly 100 lbs. Unfortunately its flesh was wasted, as it was 
exhibited and unidentified until it was too stale for food.—H. B.

ENTOMOLOGY. 
Sphinx convolvuli at Bradford.—Two specimens of SS. 
convolvuli were taken at Saltaire during August, on the 8th and 
11th respectively. Both were taken to Mr, S. Hainsworth, one 
of which he exhibited at a meeting of the Bradford Natural 
Naturalist.
