Spiders and Their Near Relatives 



Phlegmacera bryantii (bry-an'ti-i). — -This species differs 

 from the two following in the presence of several false articulations 

 in the femora of the third and fourth pairs of legs. The eye 

 tubercle is very broad. This is an Alaskan species; it was found 

 on the snows of Mount St. Elias. 



Phlegmacera occidentale (P. oc-ci-den-ta'le). — -There are no 

 false articulations in the femora, as in the preceding species. The 

 basal segment of the abdomen bears a row of spines, the median 

 pair of these is much the largest; the next four segments have 

 each a pair of humps crowned with stiff hairs. The colour of the 

 body is pale, with a large brown spot on the cephalothorax; the 

 eye-tubercle is black; and there is also a large brown spot on the 

 front part of the dorsum of the abdomen. Length of body one 

 tenth inch. Occurs in Washington State. 



Phlegmacera cavicolens (P. ca-vic'o-lens). — This species 

 agrees with the preceding in lacking false articulations in the 

 femora, but differs from it in lacking also the pair of prominent 

 erect spines on the anterior part of the abdomen. It is found in 

 caves and in other dark situations. It is widely distributed in 

 the East. 



Genus NEMASTOMA (Ne-mas'to-ma) 



This genus differs from the preceding in that the fourth 

 segment of the palpus is scarcely thickened. Four species are 

 known. 



Nemastoma inops (N. i'nops). - -This differs from the two 

 following species in that the fourth segment of the palpus is less 

 than twice as long as the fifth. It is a cave-inhabiting species 

 found in Kentucky. 



Nemastoma modestum (N. mo-des'tum).— - The dorsum is 

 granulated and armed with tubercles. Near the union of the 

 cephalothorax and abdomen there are two diverging rows of four 

 curved spines. The species has been found in California and in 

 Washington State. 



Nemastoma troglodytes (N. trog-lo-dy'tes).— - This is a cave- 

 inhabiting species found in Utah. It differs from the preceding 

 in that the dorsum is devoid of spines. 



Nemastoma dasycnemon (N. das-y-cne'mon). — This is a 

 minute species, the body measuring less than one twenty-fifth 

 of an inch in length. The legs are armed with short, acute,
