NOTES AND QUERIES. 365 
“double Turbot” (Rhombus maximus), with only a white under side to the 
head, and with one eye in the usual “notch,” May 24th; dark on both 
sides, and also spined. A nine-inch Sea Angler (Lophius piscatorius), the 
smallest I have seen locally taken, was caught in a shrimp-net on June 3rd. 
An exceptionally fine Surmullet (Mulius surmuletus) was brought in on 
June 14th; weight, 2 lb. 10 oz. — A. Patterson (Ibis House, Great 
Yarmouth). 
Sea Lamprey in Cumberland.—On the 20th of July I had the pleasure 
of weighing a fine example of the Lamprey (Petromyzon marinus). It was 
one of a pair which had ascended the river Eden, probably for the purposes 
of reproduction, and was taken near Carlisle. It scaled about 241b. I 
only mention it because, though a common fish in many English rivers, it 
is a comparatively rare fish in the north-west of England. The last local 
example that I had handled previously was taken in Morecambe Bay, near 
Ulverston.—H. A. Macruerson (Allonby Vicarage, Cumberland). 
AMPHIBIA. 
Notes on Batrachians: Frog attacking Toad. — The interesting 
paragraph in ‘The Zoologist’ (ante, p. 323) on Frogs attacking Toads. 
reminds me of a curious incident which I witnessed some time ago. I 
used to keep a number of F'rogs and similar creatures out of doors in a cool 
airy situation close to a cellar window, where they lived in harmony for a 
long time. One day, when feeding them, I remember noticing a Common 
Frog (Rana temporaria) and a Common Toad (Bufo vulgaris) both eyeing 
a tempting morsel—a worm, I believe. Suddenly the Toad seized and 
speedily swallowed the worm. The Frog remained staring at the spot 
where the worm had been, and then, as if realizing his loss, deliberately 
turned and bit the Toad over the jaw. I was much astonished at this 
exhibition of revenge on such an animal, as the worm had completely dis- 
appeared, and it certainly was not a belated attempt to obtain it. I have 
never known another instance, and I have had considerable experience in 
keeping these and similar creatures, having studied the following species : 
—Testudo graca, Emys europea, Lacerta agilis, Zootoca vivipara, Anguis 
fragilis, Tropidonotus natrix, Rana temporaria, Bombinator igneus, Hyla 
arborea (one has lived four years here), Bufo vulgaris, B. calamita, Triton 
cristatus, Lissotriton punctatus, and Salamandra maculosa. — GRAHAM

MYRIOPODA. 
Mode of Progression among Millipedes.— During a stay at Waterval-
