various other brown spots in front and at the sides. The abdomen 

 is nearly covered by circuhar brown spots around the bases of the 

 hairs, and among them are rows of larger and darker spots which 

 mark the ends of muscles running through the abdomen. Tlie 

 thorax is as wide as long, but the head is narrow and twice as high 

 as the thorax. The cephalothorax is dark brown above and below^ 

 The sternum is as wide as long and the fourth pair of legs are 

 wide ajjavt. Fig. If?, "^'he palpal organ has a long tube which starts 

 at the middle of one side, passes round the base and to the outer end, 

 where it is supported l)y a large tooth and several smaller aj)pend- 

 ages.

Pholcomma Thorell, Genera of luiropean Spiders. 



This genus was separated from llieridiiiin by Thorell, tor P. glh- 

 hum of Europe. This species has the hard skin on the back of the 

 abdomen and aixmnd tlie spinnerets and respiratory openings as in 

 Ceratmella. The body is short and round and the abdomen hairy. 

 The eyes have an arrangement much like Pholcus, the fi'ont middle 

 l)air being very small. In the species which I here refer to this genus 

 tlie eyes are all nearly of the same size. The abdomen has the hai-d 

 pieces on the back and under side, at least in the males. The back 

 is covered with scattered stiif hairs. The sternum is short and wide 

 behind. The palpal organs of the males are Tiierid ion-like, as in the 

 European P. gibbuni, and not like Veratinelhi.

Plate VI, figure 6. 

 About the size of Ceratinella Iwtah'dis. The cephalothorax is yel- 

 lowish brown, alike in both sexes. The sternum is the same color, 

 and unusually wide at the hind end. The legs are yellow-brown, 

 somewhat lighter than the thorax. Tlie abdomen is whitish, covered 

 with scattered long brown hairs. The males only have a hard spot 

 on the l)ack of the abdomen, as in Ceratinella. In some specimens the 

 abdomen has some gray spots on the under side. The epigynum is 

 slightly raised and shows the spermathecje through the skin. The 

 jialpal organs resemble those of Theridmm. Figs. Qe,/,c/. The tarsal 

 hook is wanting. The tube is slender and is supported at the end l)y 

 a short grooved appendage, which rests in a notch in the edge of the 

 tarsus.
