SOME PORTUNID CRABS 
FROM THE PACIFIC AND INDIAN OCEANS 
IN THE COLLECTIONS OF THE SMITHSONIAN INSTITUTION 
By WILLIAM STEPHENSON and May Regs! 
Introduction 
The material on which the following report is based was received 
for identification as part of a program of systematic research on the 
marine fauna of the tropical Pacific area, with studies of related faunas 
as required, sponsored jointly by the Biology Branch of the Office of 
Naval Research [Contract NONR 1354(09)] and the Division of 
Biology and Medicine of the Atomic Energy Commission [Contract 
AT (30-1)2409]. No attempt has been made in this study to incor- 
porate material previously identified and cataloged in the collections 
of the Smithsonian Institution. 
The collections as received included 96 species, but only 82 
are reported below. The remaining are western American species, 
which have been included in a monograph by Dr. John S. Garth and 
the senior author (Garth and Stephenson, 1966), and species of 
Ovalipes, which are to be included in a revision of the genus. 
Initially, 12 of the 82 species were new, but Crosnier (1962) de- 
scribed 5 of them. No doubt a considerable number of Indo-West- 
Pacific species still await description, and the time for a comprehensive 
monograph is still distant.
