chamberlin: new spiders of the family aviculariidae. 43 



slender and acute than in that species; gradually acuminate, not 

 at all clavate (Plate 2, fig. 9). 



Scopula of tarsus IV with setose line detectable proximally only, 

 the setae few, much as in the preceding species and C. boiihotei Cambr. 



Metatarsus T in the male only slightly bowed dorsad, the curve 

 mostly a little distad of point touched by inferior tibial spur when 

 joint is flexed. Inferior tibial spur slender, curved dorsomesad and 

 somewhat narrowed distad. Superior spine shorter than in C. anncc- 

 tans and straight; not expanded distad but bearing on inferior edge 

 the usual stout and closely appressed spine. 



Femur III in the male but little thickened, being 3.33 times longer 

 than wide. 



Palpus of the male with tibia not enlarged, narrowed distad. Spine 

 of bulb slender, terete, and needle-like distally; bent first a little 

 forward and then more considerably ectad. 



Male (type). Length 32 mm. 



Cephalothorax: length, 16.8 mm.; width, 13.6 mm. 



V, 



INIetatarsus I equal to or a little exceeding tibia one above. 



Clearly separated from C. annectans in the character of the palpal 

 organ, the spine being very slender and needle-like instead of com- 

 pressed. The pubescence is conspicuously darker and the posterior 

 eyes are very different in their relative sizes. It seems to be near 

 to C. honhotei Cambr., from the Bahamas, which it resembles in the 

 form of the stylus of the palpal organ, but this is longer and more 

 curved; the stridulating spines of trochanter I are much more numer- 

 ous and less clavate and are inserted over the entire length of the 

 article; and tib. + pat. I is longer than tib. -\- pat. IV. 



Calopelma,^ gen. nov. 



Ocular tubercle moderately high. Anterior median eyes a little 

 larger than the laterals to which they are clearly closer than to each 

 other.
