19 
of August, two females and five males in the birds nests on St. 
Paul's Rock in the Mid-Atlantic. 
Remarks, In spite of minor differences found in the com- 
parative length of the joints of the palps, f. inst. the tibia, which 
is longer, not shorter than the femur, with the inner margin mode- 
rately not strongly convex, I refer my specimens to Ch. garypoides" 
Ell. from Portuguise Guinea. In spite of the wanting accessory 
teeth of the fingers of the palps I think, that the described species 
is somewhat related to the Ch. argentinus Thor. 
Chelifer nova-guineensis n. sp. 
(Pl. II, figs 9—12; textfigs 5—6). 
åd. 
Cephalothorax. No distinct ocular spots.  Cephalothorax 
distinctly longer than wide without transverse sutures. The skin 
is almost smooth and provided with fairly long and stiff, somewhat 
dentated hairs. 
Abdomen. The abdomen is very long and slender, without 
a distinct longitudinal line. The skin is almost smooth. From 
10—12 long dentated hairs are placed along the hindmost margin 
in addition to six hairs in front of the row in the median segments. 
Last segment with "tactile” hairs. The genital area is of the Ck. 
birmanicus Thor. type. 
Antennae. The long and slender galea is attenuated without 
distinct teeth and extends somewhat beyond the terminal hair. The 
serrula consists of 25 teeth and the flagellum of four hairs. 
Palps (pl. II, figs 9—11; textfigure 5). The maxillae are 
almost smooth. The palps are minutely, but distinetly granular on 
the posterior surface of the trochanter and the anterior surface of 
the femur, indistinetly granular on the anterior surface of the tibia, 
but else more or less smooth. The hairs are fairly long and stiff 
and with a few teeth; ”tactile” hairs are found posteriorly near 
the tip of the femur, the base of the tibia and the hand; the movable 
finger is provided with two rather thick ''tactile” hairs in addition
