170 NOTES. of the above-mentioned "school" of white-beaked dolphins. They were first seen by the pilot of the iron railway bridge at Alresford, and by Mr. Barton, of Alresford Lodge, near the bridge, but whether the "school" consisted of seven or nine is not quite clear. Mr. Barton armed himself with his rifle, and, from a punt, shot at several, and managed to capture two. One specimen was 9 feet 6 inches long (probably an adult), and the other 6 feet 6 inches, both being females. One that he shot at got into deeper water, and was picked up next day by Henry Barr, a fisherman at Wyvenhoe, being 9 feet 6 inches long, adult, sex not noted. Another of his wounded ones, also 9 feet 6 inches long, was captured by the crew of the yacht "Valfreyia." Thus, five specimens were taken at one time of this rare dolphin in our river. [The fate of Dr. Laver's example of this interesting Cetacean and, also of many other rare animals, constantly occurring in Essex, points to the necessity for the establishment of the long-talked-of Local Natural History Museum, by the Essex Field Club, where such specimens would be received and conserved. The opportunity of securing another Essex Delphinus may possibly not occur again, if there be a "schoolmaster" abroad among the dolphins to warn his pupils of the end of five of the confiding animals who were so foolish as to visit the inhospitable waters of the Colne.—Ed.] Little Gull at West Mersea.—I saw to-day, at Mr. Pettit's, a Little Gull (Larus minutus, Pallas), shot on October 30th, 1889, at West Mersea. It is a very good specimen, but it is in immature plumage. This species is, I think, rare on our coast.—Henry Laver, F.L.S., Colchester, November 2nd, 1889. Dwarf Form of Euchloe cardamines in Epping Forest.—"On May 22nd, 1889, while insect hunting in Epping Forest, I took a very small male of this species hovering over the flowers of the Wood-parsley (Anthriscus sylvestris). The insect is barely 11/8 inch in expanse.—James A. Simes, 4, Cricketfield Road, Clapton," in "Entomologist" for August. Immense Congregation of Snakes at Ashingdon.—Reading as follows in the "Essex Weekly News," of August 23rd, 1889, under Ashingdon :—"On Thursday, August 15th, as some men at Mr. Jolly's (Moon's Farm) were clearing away some rubbish out of the stackyard, they came upon a nest of snakes, adders and sloeworms (sic). They managed to kill 303, and several others made their escape "— I wrote to get some further particulars of this curious find, and received the fol- lowing reply from Mr. Thomas Cooper, of Moon's Farm, dated September 2nd :— "In reply to your letter of the 28th August, there was a large quantity of snakes found in some cavings in the stockyard on Moon's Farm. I helped a boy to kill 234, and the next day two men killed 69 more, besides destroying a large quantity of eggs, which would make snakes destroyed 303. We saw no adders, neither have we seen the report in the paper, so that I cannot say if the report is correct or not." I see no reason to doubt these facts, which certainly are interesting, and quite eclipse those in my former note in E. N., i. p. 112. "Cavings," are short straws, broken ears, &c., left after thrashing. Snakes have run very large this year, I have had several from 35 to 38 inches long—Edward A. Fitch, Maldon.
