Explanations and Acknowledgments 



All stomatopods in the Hancock collections, 1933-1938, are here 

 reported upon with the exception of larval specimens and juveniles too 

 young for satisfactory specific determination. 



Indispensable to any stomatopod study is Kemp's "Account of the 

 Crustacea Stomatopoda of the Indo-Pacific Region based on the Collec- 

 tion in the Indian Museum," Mem. Indian Mus., Vol. 4, No. 1, 1913. 

 Equally useful to any student of the west coast forms is Bigelow's 

 "Report upon the Crustacea of the Order Stomatopoda collected by the 

 Steamer Albatross between 1885 and 1891, and on other Specimens in 

 the U.S. National Museum," Proc. U.S. Nat. Mus., Vol. 17, No. 1017, 

 1894. 



In the synonymy under each species, in addition to the citation of the 

 original description, reference has been made to both Kemp and Bigelow 

 wherever possible, along with other pertinent papers, and any that have 

 come to my attention since Kemp's monograph was published. 



In place of the diagnoses usually given, especially for new species, 

 in taxonomic works of this sort, rather detailed keys to the west coast 

 species have been introduced for the purpose of facilitating identification. 

 Many keys, striving for conciseness, become altogether too brief. I hope 

 I have not erred in the other direction. The added information, printed 

 in smaller, eight-point type, was found very useful in the more careful 

 comparison of closely related species, and may again prove so to those 

 who may have occasion to use this paper. In all instances the terminal 

 tooth or spine of the raptorial dactylus has been included in the count of 

 the teeth arming its inner margin. 



Notes on color, unless otherwise stated, are based on alcoholically 

 preserved specimens. These notes chiefly concern color markings that 

 have proved to be more or less permanent and which, therefore, may be 

 of some use in the recognition of certain species. This is especially true 

 of a number of the Squilla species, including specimens of some described 

 by Bigelow nearly half a century ago. On the other hand, color, as a
