and subcqual in size, only the anterior median ones slightly but 

 distinctly smaller than the others. The eyes of the anterior row 

 are separated from each other by equal distances measuring less 

 than their diameter, but more than their radius. The same is true 

 of the posterior row, the greater length of this row being due to 

 the equal size of its eyes and to the ever so slightly greater distance 

 between them. The rows are to all purposes parallel and the 

 free distance between the rows is twice the diameter of the eyes. 

 The quadrangle of the median eyes is therefore considerably longer 

 than wide. The clypeus is unusually narrow, measuring less 

 than the diameter of the anterior middle eyes. It may be added 

 that the eyes of the anterior row are quite plainly visible, while 

 those of the posterior row are discernible only when the light falls 

 under a certain angle. 



The spinnerets are well preserved on specimen No. 5898 (now 

 No. 90). The anterior pair is almost contiguous. They have the 

 appearance of brown discs with a smaller and well circumscribed 

 disc inside llic larger. 'Hiis represents ])robab1y the terminal arti- 

 cle of the si)inneret, but no spinning tubes are discernil)le. The 

 posterior spinnerets are smaller and are separated from each 

 other by at least their diameter. Between the posterior spinnerets 

 there is a darker area possibly representing the median spinnerets. 

 In front of the spinnerets the colulus can be plainly seen as a small 

 brown disc. 



The first and second pair of legs are broken off apparently 

 across the tibiae. The third and fourth pair are complete. Scud- 

 der did not see the ends of their tarsi. When fully exposed the 

 third leg measures 9.8 mm., the fourth — 19.2 mm. The length 

 of the femora is given correctly by Scudder as follows : — First 

 femur 8.75 mm., second — 7 mm., third — 3.5 mm., fourth — 7 mm. 

 One can see median and lateral spines on all femora and tibiae and 

 some spines on fourth metatarsi. The hair is very faintly visible 

 on legs, but is indiscernible elsewhere.
