BrEEDING Hasits oF Spipers.—On the afternoon of the fifth 
of June we were lying on the ground in a dry pasture looking 
among the short grass, when we noticed a pair of crab spiders, 
Aysticus, under a slanting grass 
leaf. The female stood head fe 
downward holding on by a few N 
threads across the leaf (see figure). ° IE o

abdomen and his right on the g 
grass leaf. He stood there for a few minutes, now and then 
working his palpi up and down, then ran up over the female 
several times and settled himself in the position in the figure over 
the end of her abdomen with his head just behind her epigynum. 
After a few moments when he appeared to have his palpus in use, 
we pushed away the surrounding grass and broke off the leaf on 
which the spiders were, without disturbing them in the least and 
found the left palpus in the epigynum with the spinal muscle M 
inflated. The size of this muscle varied continually, swelling out 
to its full extent in a sausage shape, and then slowly contracting. 
We watched him for ten minutes during which he removed his 
palpus once and inserted the same once again. We then put grass 
and all into a bottle without disturbing the spiders, but when we 
looked at them again on reaching home they had separated.—F.

Nores on New anp Rare Fisues oF THE Pactric Coast.— 
It was until recently currently believed that very few additional 
Species would be found upon the Pacific coast of the United 
States. The publication of descriptions of three new flat-fishes 
and a scomberoid form, in 1879, threw some little doubt upon 
this idea, and the discoveries since made, both by Prof. S. Jordan 
and by the writer, will, when the results are published, prove © 
beyond a doubt that the Pacific icthyological fauna is far richer ` 
` than it was supposed to be, and probably richer than the Atlantic. 
The Pacific is z%e ocean of the world—the main body of its 
waters are collected in its vast expanse, and it is only natural to 
Suppose that when men of the more advanced civilizations have 
Searched its shores and its depths as thoroughly as they have 
Searched those of the smaller Atlantic, it will be found that its 
fauna is rich in proportion to its larger dimensions. If we con- 
fine our attention solely to the west coast of North America, we 
shall find that several groups are peculiar to the region, or are at 
most represented only by scattered species elsewhere; while 
others that are tolerably well represented in the Atlantic have 
; headquarters here.
