fornia" to localities inside the Gulf; and "Mexico" to Mexican locali- 

 ties south of a line drawn between Cabo San Lucas and Mazatlan. 

 "Clipperton Island" and "Galapagos Islands" are listed separately. In 

 all other cases the name of a country forms the main heading. 



For consistency, Latin American localities are cited in the form 

 given in Index to Map of Hispanic America ("Millionth Map") (U. S. 

 Government Printing Office, 1945). The few place names not appearing 

 in that work are cited according to the Allan Hancock Pacific Expedi- 

 tions station list (Fraser, 1943). 



Diagnosis: Under this heading appear the characters most useful in 

 separating the species from its congeners. 



Description: A full description of the species, except that characters 

 common to all members of the genus and included in the generic des- 

 cription are not repeated. 



Variations: Under this heading appears additional descriptive in- 

 formation, often referring to atypical specimens. 



material examined: When no more than four lots of specimens were 

 examined, pertinent data are listed here. In all other cases reference 

 is made to the appropriate table in Appendix I. 



Measurements: These include carpace lengths of the largest and 

 smallest males, non-ovigerous females, and ovigerous females examined, 

 and reference to measurements of other specimens. 



Color: Color notes on living material of several species, prepared 

 by Anker Petersen, formerly staff artist of the Allan Hancock Founda- 

 tion, are published for the first time. The color terminology adopted 

 by Mr. Petersen is from Ridgway, Color Standards and Color Nomen- 

 clature (Washington, D. C, 1912). Other color notes have been ex- 

 tracted from the literature. 



Ecology: Under this heading are included such data as bathymetric 

 range, substrates, commensalism, and months in which ovigerous fe- 

 males were encountered, as determined from the present study and 

 from the literature. 



Relationships: A discussion of the affinities of the species with 

 closely related forms. 



Remarks: Any pertinent information not included under the above 

 headings. 



Range: A brief summary of the complete range of the species in- 

 sofar as known, as determined from the present study and from previous 

 records.
