improbable. Among these other “arthropods” were hundreds 
of harvestmen collected together in shallow hollows beneath 
the overhanging banks of a small stream. ' These were arranged 
in close proximity to one another with their long legs bent up- 
ward, thus making a very peculiar appearance. There were sev- 
eral species of these, but each species was congregated by itself. 
Several species of Hesj)eridae were also observed to be collected 
in a similar manner, clinging close together, to overhanging 
hollows beneath the bank, each species for itself. 
The characters of the A . elongatus from Guatemala tally very 
nicely with the description by Mr. Banks (I) and I deem it 
unnecessary to give any extensive description here, except to 
state that they measure three millimetres in length and are 
dark brown with the legs much lighter. 
I tried to determine the sexes of the specimens collected (22 
in number), but was not successful. I had concluded that the 
s])ecimen figured was a male, but a study of sections made from 
this after having completed the drawing showed it to be a gravid 
fertilized female (Plate X). I counted from thirty-five to forty 
apparently well developed eggs in the ovary, and I estimated 
that a bunch of spermatozoa found in the oviduct, just inside 
the genital opening, consisted of not less than two hundred 
individuals, and there may have been twice that number. These 
facts clearly show that the female is fertilized prior to the laying 
of her eggs and that the spermatozoa may be retained by the 
female at least for some short time (if not for a longer time) 
before the eggs are fertilized and laid. 
All the longer hairs upon the figure (Plate XXXI) are exactly 
as in nature. All hairs upon the dorsal scutae, the top of the 
cephalo-thorax (a few very small ones omitted), the edges of the 
cephalo-thorax and the mouth parts, or chelae, are exactly as 
in nature. 
Specimens of pseudoscorpions will be gratefully received and 
exchanges made when possible.
