Figs. 239-248. Lassenia spinifera n. sp., female: 239, trochanter and femur of palp, anterior; 240, anus; 241 
tibia and tarsus of palp, anterior; 242, palp, posterior; 243, tarsus I, showing setal types; 244, coxae III and IV 
245, chelicera; 246, dorsal hysterosomal setae; 247, end of chelicera; 248, gnathosoma, ventral. 
thid and companion seta at O.llad and a 
second eupathid at 0.92 p (Figs. 255, 258, 
260). The famulus is inserted on a somewhat 
vesicular alveolus, but this is not as promi- 
nent as in L. lasseni; moreover, the tip of the 
famulus tapers to a fairly sharp point and is 
not expanded at the tip as it is in the type 
species. Tarsus II with S 2 at OAOd, famulus at 
0 .6ld of the same form as found on tarsus I, 
a peripectinate eupathid and companion seta 
at 0.6ld and a second eupathid at 0.94p. 
Tarsus III with a single eupathid at 0.92 p. 
Most normal setae of legs bihemipectinate, 
the pectinations visible at magnifications of 
200 x and higher; total number of normal 
setae on legs about 145, compared with 240- 
245 in L. lasseni. Other features of chaetotaxy 
as shown in the accompanying table. Three
