FOREWORD 



The stomatopods of the Hancock Expeditions (1933-38) form as 

 interesting a collection of Crustacea as ever I have had the pleasure of 

 studying. With a sense of lasting gratitude, I dedicate this paper to Cap- 

 tain Allan Hancock, of Los Angeles and Santa Maria, California, who 

 made possible the expeditions on M^hich these stomatopods vi^ere collected 

 and the publication of this report upon them. 



INTRODUCTION 



Until now, 5 genera and 17 species^ of stomatopods had been reported 

 from the Pacific shores of American and adjacent islands. As a result 

 of the investigations of the Hancock Expeditions, it is now possible to add 

 to that number: (a) a genus and species by virtue of the discovery of the 

 rare Atlantic Coronida bradyi in the Galapagos Islands, where it seems 

 fairly abundant; (b) a common Indo-west-Pacific stomatopod, Lysio- 

 squilla maculata, for the first time taken east of the Hawaiian or Mar- 

 quesas Islands, at La Libertad, Ecuador; (c) 6 new species and what 

 appears to be a new subspecies of an already known species taken by the 

 Hancock Expeditions; (d) 2 species newly named which are based on 

 formerly merely lettered varieties of an old species; and (e) a seventh 

 new species described from material collected by Dr. S. F. Hildebrand 

 at Panama. This species is introduced here with Captain Hancock's 

 kind permission, in order to render this account of west American 

 stomatopods as complete as possible for the purpose of encouraging and 

 facilitating further studies upon them. To that end, rather complete
