Verrill (1914, p. 18) undertakes to divide the region with which we 
are here concerned into three ‘‘faunal districts’’: 
**The Columbia-Alaskan,’’ including ‘‘the coasts and islands of Alaska, south 
of the Aleutian Islands, and the entire coast of British Columbia, with Vancouver 
Island; Puget Sound, and the northwestern coast of Washington; the Gulf of 
Georgia; and the Straits of Fuca’’; ‘‘The Californian,’’ including ‘‘the middle 
and southern parts of the coast of Washington; all of the Oregon coast; and the 
coast of California to Point Conception, or the north end of the Santa Barbara 
Channel’’; and ‘‘ The South Californian,’’ including ‘‘the coast of southern Cali- 
fornia, from the Santa Barbara Channel, Santa Rosa Island, and Santa Cruz 
Island to the middle part of the Lower California coast.’’ 
His districts, however, in the light of the remarks he makes con- 
cerning them, do not seem to be very well founded and can without 
difficulty be merged into the one large area of which they are but 
arbitrary subdivisions. For example, regarding his Columbia-Alaskan 
and Californian faunae he says (1914, p. 348) : 
The former includes a total of eighty-five species and named varieties; the 
latter includes forty altogether. For my present purpose these may best be con- 
sidered collectively, as they have many species in common.3 The two lists include 
ninety-nine species, subspecies and varieties. Of these, only sixteen species and 
varieties are not known to occur in the Columbia-Alaskan fauna, while twenty- 
four are common ‘to both. Of the ninety-nine forms, only eight are of Arctic 
origin...leaving nine[ty]-one that may be considered as characteristic of the 
region. 
And, with respect to the South Califorma fauna (1894, pp. 345 and 
349) : 
So far as known, this fauna has few species peculiar to it. The species are 
largely members of the more northern faunae that extend far south, and partly 
species of the more southern fauna of Lower California and the Gulf of California 
that range northward beyond the normal limits of that fauna....The list given 
... includes twenty-nine species and varieties. Of these, twenty-two occur farther 
north.3 Of the remaining six species, three are known to occur in the Panamie 
fauna, and probably find.here their northern limits....The remaining three, at 
present, seem to belong particularly to this fauna....This faunal district, as 
now known, does not show any special peculiarities of its own. It is a meeting 
ground, so to speak, between the Panamic and Californian faunae. 
According to Dr. Wesley R. Coe, the ‘‘Nemerteans of the Pacific 
Coast’’ (1910, p. 118), also exhibit considerable continuity in their 
distribution. Of the thirty-two species enumerated from Alaska 
nearly one half, fourteen, ‘‘were found also on the California coast 
during a single summer. 
Eleven of these forms, which are common both to the California 
coast and to Alaska, were found at Monterey Bay, ten at San Pedro 
or in the deep water in the vicinity, while only two were collected at
