VII. APPENDIX I 
DISTRIBUTIONAL LIST OF THE MARINE DECAPOD CRUSTACEA OF CALIFORNIA 
This list is almost wholly based on the one given by Miss Rathbun 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 italicized. 
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 ©. 
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 bétween 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 codst of California. 
Records of species from 100 fathoms or less are indicated by circular black spots, 
@; those between 100 and 500 fathoms by a circle with a dot at the center, 0; 
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 Tsland 
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
