ÅMPHIOXUS IN THE BermMupAs. — It may interest the readers of The 
Naturalist to hear that Amphioxus has been discovered in the Bermudas. 
Mr. J. Matthew Jones and I have dredged it in the swift tide-way near 
the bridge at Flatts Village. The animals vary in length from three 
quarters of an inch to an inch and a half, and appear to be quite abun- 
dant in a belt of coarse sand in two to three fathoms of water. — G. 
Brown Goopr, Hamilton, Bermuda, April 4, 1877. 
THELYPHONUS GIGANTEUS POISONOUS. — Dr. H. C. Yarrow for- 
warded us in February, 1875, a specimen of this arachnid, with a letter 
from Dr. J. F. Broughter, of Fort Craig, New Mexico, in which he 
states his belief that this animal is poisonous, and adds, “ I know the 
Mexicans here regard it as extremely poisonous.” He incloses the fol- 
lowing extract from a letter of Dr. Lewis C. Kennan, of Santa Fé, N. 
M 
“In regard to the Thelyphonus giganteus, I have no doubt of its ven- 
omousness; I can demonstrate the poison apparatus. While stationed at 
Fort Buchanan, on the border of Sonora, in'1855, I knew an Indian boy 
bitten on the temple who never recovered. Several horses were bitten 
on the lip, champing the insect in their hay, and the tumefaction and 
general distress were as great as from the bite of a rattlesnake. The 
insect is so extremely sluggish that great violence is necessary to make 
them bite. I had a French servant who frequently brought them to me 
in his hands and pocket, and I even suspected the omnivorous Gaul of 
cooking and eating them as a sort of land lobster, but they never 
troubled him in any way. The belief in their venomousness is universal 
in Mexico. To my mind the fact is beyond question. If not, what is 
the teleology of the fangs?”

We may state what is not mentioned in Professor Thorell’s paper, that 
he found several species of spiders-in Colorado, closely allied to North- 
eastern Asiatic forms. This is confirmatory of our statement in the 
Monograph of the United States Geometrid Moths, that we found sev- 
eral Colorado moths of this family closely allied to those found on the :
