COMPLETE HAIG: EASTERN PACIFIC PORCELLANIDAE 



Explanation of Plates 



Every species treated in this report is represented by a toto-illustra- 

 tion, with the exception of Polyonyx nitidus Lockington. That species 

 differs from P. quadriungulatus Glassell only in very minor characters, 

 w^hich are shown in text-figure 12. The illustrations of Minyocerus kirki 

 Glassell and Ulloaia perpusillia Glassell are from drawings by Anker 

 Petersen (after Glassell, 1938a). All other species, with the exception of 

 Pachycheles velerae, Porcellana corbicola, and Poly onyx con finis, new 

 species, are illustrated by photographs of specimens from among the 

 material examined. Those three species, as well as thirteen other new 

 species and one new subspecies described herein, are illustrated by 

 drawings. 



The photographs were taken by Mr. Francis Munger; the drawings 



are by the writer.
