spiders here in the Museum of Comparative Zoology, I found a vial 
containing what appears to be a male and a female belonging to a new 
species of the genus Anisaedus Simon, which has previously contained 
only one species from the Western Hemisphere, A. gaujoni Simon, 
1893 from Ecuador. The label in the vial gives the locality of col- 
lection as simply “West Indies.” The writing appears to be that of 
Miss Elizabeth Bryant, who was in charge of the collection of 
arachnids in this Museum for many years. In view of the rarity of 
spiders in this genus and after some discussion with colleagues, the 
decision has been made to describe these specimens as representing a 
new species in spite of the indefinite type locality. Types of the new 
species described in this paper will be deposited in the Museum of 
Comparative Zoology, Harvard University.

The species is named after Dr. Herbert W. Levi, Associate Cura- 
tor of Arachnology in the Museum of Comparative Zoology at Har- 
vard University. 
Male holotype. Total length 4.81 mm. Carapace 2.21 mm. long; 
1.58 mm wide opposite second coxae where it is widest; about .67 mm 
tall ; pedicel quite well exposed by separation of cephalothorax and 
abdomen ; general shape about like that of Otiothops ; median thoracic 
groove a well defined short groove in the upper and steeper third of 
the posterior declivity; surface finely granulate. Eyes: eight in two 
rows (Fig. 1) ; posterior row slightly wider than anterior row; AME 
circular; all others oval or irregular to some degree; viewed from 
above, anterior row gently recurved ; posterior row definitely pro- 
curved ; anterior medians slightly raised from general surface and 
directed anterolaterally. Ratio of eyes AME : ALE : PME : PLE 
= 11:6:5: 5.5 (irregularities in shape of all eyes except AME 
make it difficult to measure with desired accuracy). Viewed from in 
front, anterior row gently procurved, measured by centers; posterior 
row strongly procurved. AME separated from one another by about 
their diameter; from ALE by slightly more than three quarters of 
their diameter. Height of clypeus equal to about 2.3 times the diam- 
eter of AME; deeply grooved just above ventral margin. PME 
separated from one another by a little less than four times their 
diameter, from PLE by slightly less than that distance. LE separated 
from one another by nearly the radius of ALE. Central ocular 
quadrangle slightly wider in front than behind and slightly wider
