594 General Notes. [August, 
little excrementitious matter. This specimen was lost, but I 
shortly after found another with the old skin hanging to the body 
in the same position, but in this case filled with eggs. This one I 
succeeded in mounting in carbolated water, and so preserved it 
for future reference. In the normal state these creatures measure 
about .016 inch in length, but when gravid, or after depositing 
the eggs in the sack, they are much larger. My specimens were 
obtained from the sediment in a small aquarium in my sitting 
room, which contains a few native plants and fishes, and has 
about an inch of sand in the bottom, which was taken from the 
river bed last fall. The aquarium swarms with Protozoans, and I 
have thus far found seventeen Tardigrades, and there are probably 
many more. The genus I suppose to be Macrobiotus, but do not 
know that it has a specific name. It is the same that was found 
by Prof. Bessey in this place several years ago. I send drawings 
for identification —F/. E. L. Beal, 
An ABNORMAL Foor IN AmBtysroma.-—In a specimen of 
Amblystoma punctatum Baird, which I found in Williamstown, 
Mass., the second or largest toe of the right hind foot presented 
an unusual abnormality, being bifid at the tip. e osseous 
skeleton showed the same peculiarity, there being two terminal 
phalanges articulating with the penultimate one.— F. S. Kingsley. 
Notes on Myriopops.—I have recently found several species 
of Myriopoda in Williamstown, which are of interest from the 
fact that their known localities are very few. Among these are 
Pauropus huxleyi Lubbock, Eurypauropus spinosus Ryder, and 
Trichopetalum lunatum Harger. Pauropus huxleyi, an English 
species, has heretofore been only reported from Fairmount Park 
by Mr. Ryder, which also was the only known locality of Eury- 
pauropus. Trichopetalum has been found in New Haven and in 
Philadelphia. The locality where the specimens were found was 
on “Stone Hill,” a iimestone elevation, and with them were asso- 
ciated large numbers of Campodea staphylinus Westwood. I might 
also state that I have found here Helix asteriscus Morse, it being 
its first occurrence in Massachusetts.— 7. S. Kingsley. 
Seconp FLIGHT or DraGon-FLIES—I have now to report that 
last evening (May 24th), on the top of West Hill, in Melrose, I 
witnessed what to all appearance was a movement precisely like 
that of last year (see this journal, Vol. xiv, p. 132). “The. mes 
were moving over the hill in a business-like fashion, all going 10 — 
the same direction, from one to six being in sight at once. I 
=- watched them for nearly half an hour and they weré still passing 
when I came away. Nobody could see them, I think, without 
being convinced that they were moved by a common impulse, 7, 
for myself, I can hardly doubt that such migrations will be foe 
to be things of regular occurrence. What their occasion an 
design are I am not entomologist enough even to guess. 
should be glad to be enlightened.— Bradford Torrey.
