192 General Notes. [February, 
ABERRATION IN THE PERCH.—I wish to note a peculiar ana- 
tomomical aberration in a common perch (Perca americana) 
which has just come under my observation. In examining some 
of these fishes from Lake Michigan, an assistant noticed that one 
of them had no pyloric cceca. The viscera were placed in alco- 
hol with others, and on opening the alimentary canal for the pur- 
pose of removing its contents, I noticed a fleshy mass apparently 
nearly occluding the pyloric opening, the pyloric portion of the 
stomach being stretched somewhat tightly over it. Finding that 
this was not detachable I took it for a tumor, but a closer examina- 
tion showed that it was divided into three finger-like lobes, of the 
shape and size of pyloric tubes, and that each of these lobes was 
hollow, opening upon the outer surface of the intestine by an ori- 
fice large enough to admit a knitting-needle. Evidently these 
were the missing pyloric coeca, which had grown wrong side out ; 
for I cannot conceive of any accident which should turn these 
structures within the body of. the fish. 
The exposed surface is a mucous surface, and that within the 
cavity of the pyloric tube is a serous surface, like that of the out- 
side of the intestine.—S. A, Forbes. - 
A LIZARD RUNNING WITH ITS FORE FEET OFF THE Grounp.— 
In the proceedings of the Linnean Society of New South Wales, 
1884, it is stated that Mr, Macleay exhibited a lizard which was 
observed to run for six yards in an erect posture with. the fore 
legs quite off the ground. The lizard was of the genus Gramma- 
tophorus, of which there are several species in the country, all 
of them much given to playing and gambolling on sunny days. 
FEATHERS OF THE Dopo.—The feathers of the dodo have been 
studied by Professor Moseley,who read a paper on the subject at 
the Montreal meeting of the British Association. He showed 
birds of the dove family, near which the dodo is placed. Earlier 
in the development of the dove’s feathers the filoplume are 
larger, relative to the size of the other feathers; and this condi- 
tion resembles still more the structure found in the dodo. 
THE _ARMADILLO IN TExas.—G. H. Ragsdale, of Gainesville, 
Texas, informs me that an armadillo was recently killed in northern 
Denton county, Texas, which is the only animal of the kind ever 
taken in that part of the country. The armadillo is said to have 
been common on the Rio Grande river twenty years ago, and is 
still;common in the south-western counties of Texas.—A. Hall 
(E. Rockfort, Ohio), in Forest and Stream.

Hart Merriam’s interesting work on the Mammals of the Adir- 
ondacks (New York, 1884), the author states that with the ex-
