very much damaged, most of the legs being reduced to fragments, 
and the color of the abdomen entirely lost. The foremost row of 
eyes appears to be slightly longer, or at least is not shorter, than 
the middle row; the interval between the anterior central eyes is 
evidently greater than the intervals between them and the anterior 
laterals, which appear to be slightly smaller than the anterior 
central eyes. The area occupied by the four posterior eyes is 
longer than broad in front, but shorter than broad behind; the 
interval between the two large eyes of the middle row is nearly 
double as great as their diameter; the interval between the two 
eyes of the hindmost row equals the length of the middle row. 
The cephalothorax is brown, its sides covered with coarse ap- 
pressed, olivaceous-grayish hair; all along the back it has a broad 
paler band covered with grayish-white hair, which stretches from 
the middle row of eyes nearly to the hind margin of the cephalo- 
thorax, filling up the area between the four posterior eyes, some- 
what dilated and rounded in the sides just behind this area, and 
then tapering gradually backwards. The sternum and the under 
side of the coxe are brownish-testaceous, clothed with grayish 
hair; the mandibles are piceous, covered with coarse grayish hair 
at the base, black-haired towards the apex. The legs are brown, 
very distinctly black-ringed, covered with shorter grayish and 
longer black hairs. Length of the example: seven millim.; 
length of its cephalothorax three millim.; legs of the fourth pair 
eight and one-half, patella and tibia of that pair three millim. 
By the form of the band along the back of the cephalothorax, 
as also by several other characteristics, this species would seem 
to be identical with Zarentula exasperans Cambr. (loc. cit., p. 283, 
Pl. VIII, fig. 7); but in that species the foremost row of eyes 1S 
said to be the shortest of the three, whereas in the spider before 
us the middle row is as short as, if not shorter than, the foremost.

THELYPHONUS OFFENSIVELY Oporous.—In the Naturalist, X1. p. 
367, the poisonous nature of the whip-scorpion (7) helyphonus 
giganteus) of Mexico and adjoining portions of the United States 
was described. That it emits from its “whip” an extremely 
offensive smell, is stated by Mr. E. Wilkinson, Jr., in a letter to 
the Smithsonian Institution. The animal was found under stones 
near Chihuahua. “After considerable difficulty,” he writes, “ I 
succeeded in capturing him, but not, however, until I had received 
several doses of his powerful effluvia, which obliged me each time 
to retreat and catch a fresh breath.” 
Tue Parer Nauritus IN Froripa—It has been doubted by 
some naturalists whether the Argonaut, or paper nautilus, occurs 
on the Florida coast. Two paper shells have been found here 
this winter, and last winter one was found with the animal entire, 
besides another empty shell. Its habitat is probably in tropical
