THE GENUS OONOPS (ARANEAE, OONOPIDAE) 
IN PANAMA AND 
THE WEST INDIES. PART 3'* 
By Arthur M. Chickering 
Museum of Comparative Zoology 
This is the eighth paper in the series on the various genera in the 
Family Oonopidae as it is now known in Central America and the 
West Indies. It is the third and final paper on the genus Oonops 
and deals with this genus as it is now known in the West Indies 
from the Virgin Islands, both American and British, westward to 
Trinidad, W. I. and Curacao, Netherlands Antilles. My own col- 
lections have been supplemented by the loan of specimens from the 
American Museum Natural History and the British Museum (Nat- 
ural History) together with specimens deposited in the Museum of 
Comparative Zoology from earler collections. 
Dr. W. J. Gertsch, formerly Curator of Arachnida in the Ameri- 
can Museum of Natural History, New York City and Dr. J. A. 
L. Cooke, Associate Curator of Arachnida in the same institution 
have loaned me specimens of this genus from the West Indies. Dr. 
J. G. Sheals and Mr. D. J. Clark, Dept, of Zoology, British Museum 
(Natural History) have very kindly made it possible to examine 
three species of the genus Oonops described by E. Simon from St. 
Vincent, B. W. I. in 1891. 
As I have repeatedly acknowledged in my published papers, I am 
deeply grateful for help and encouragement extended to me by mem- 
bers of the staff of the Museum of Comparative Zoology over a 
period of many years. Grants GB-1801 and GB-5013 from the 
National Science Foundation have given me financial aid for a period 
of nearly six years. 
Numerous difficulties encountered during the study of this genus 
in the West Indies, mentioned in Part 2 of this series, have con- 
tinued in this division of the study. This has been further com- 
plicated by increasing infirmities of advancing age. For these reasons 
this paper is somewhat less complete than originally planned. A 
small number of specimens have been laid aside because of uncertainty 
concerning their status and lack of sufficient time to clarify the 
problem. 
In view of what I have written above, the list of species from 
the region under consideration in this paper and at present recog-
