VII. APPENDIX I 



Distributional List of the Marine Decapod Crustacea of California 



This list is almost wholly based on the one given by Miss Kathbun in her 

 Harriman Alaska Expedition Report (1904a, pp. 8-17), with some additions from 

 the U. S. National Museum collections, and several of the more recent authors. 

 The species are in systematic order in the first column of the table. All of those 

 dealt with in the section on "Distribution'"' (p. 281) are in roman type. Those 

 taken in connection with the biological survey of San Francisco Bay are printed 

 in bold face type, while species from depths exceeding 100 fathoms are italicised. 



Since drawing up this table it has been found desirable to distinguish between 

 the species whose bathymetric range is not known to exceed 30 fathoms and those 

 which, though found within the 100-fathom line have not been taken, at least off 

 the California coast, in 30 fathoms or less. The names of the former are followed 

 by a black spot •, the latter by a C 



In the second column the northern limits of the ranges of the various species 

 are given. In the case of Alaskan forms these as a matter of convenience, have 

 been reduced to one of several generalized limits, i.e., Sitka, for all species whose 

 range terminated there or between that point and the northern boundary of British 

 Columbia; Kadiak, for the Sitka to Kadiak species; and the Aleutian Islands, for 

 those reaching, but not running into the Bering Sea. As a matter of interest the 

 northern limits of all species reported from the Straits of Fuca or Puget Sound 

 have been marked with an asterisk.* 



The southern limits given in the next to the last column have been similarly 

 grouped in the case of Lower Californian species under Todos Santos Bay, San 

 Geronimo Island, Point San Eugenio (Cerros Island), Magdalena Bay, and the 

 Gulf of California, respectively. 



The last column gives records of exceptional occurrence and of world distri- 

 bution. 



The remaining nine columns cover the distribution along the coast of California. 

 Records of species from 100 fathoms or less are indicated by circidar black spots, 

 • ; those between 100 and 500 fathoms by a circle with a dot at the center, ; 

 and over 500 fathoms by a o. 



In a number of instances these symbols are accompanied by one or more index 

 figures. When standing alone, an index figure signifies that the species in ques- 

 tion has been found only at the locality referred to within the region delimited 

 by the heading of the column in which it occurs; a plus sign (+) preceding the 

 figure indicates that the species has also been found at the locality for which the 

 index figure stands. Obviously where the stated northern and southern limit of 

 a species restricts it to a particular locality the use of an index figure is unneces- 

 sary, yet they have been employed in all cases where one has been available. 



The index figures and the localities for which they stand are: 



1. Pigeon Point 7. San Clemente Island 



2. Point Conception 8. San Nicolas Island 



3. Santa Barbara Channel 9. Santa Barbara Island 



4. Laguna Beach 10. Half Moon Bay 



5. San Francisco Bay .11. Humboldt Bay 



6. Santa Barbara 12. Farallon Islands
