474 The Long-Jawed Goby. [ August, 
dicates a line of communication, intercourse, traffic, and possibly 
migration by the way of the Gulf of California and the Colorado 
River. If the Olivella is O. biplicata, and the beads, which it is 
said are as thin as a wafer and of the circumference of an ordi- 
nary pea, are what I suspect,! then we have a right to infer that 
these interior people were in communication directly or indirectly 
with the California tribes north of what is now known as Lower 
California. If any of the shell ornaments are made of some 
species of Busycon, then communication with the Gulf of Mexico 
is implied. 
If all of the shells cited by Mr. Barber, and involved in doubt 
by the indefiniteness of his paper, are actually represented in the — 
material collected, then the whole question as to the origin, dis- 
tribution, and characteristics of the extinct tribes of Colorado, 
Utah, and Arizona is still further complicated, for it indicates 
intercourse, traffic, and perhaps migration in three directions, and 
the relations of these interior people with the maritime or coast 
tribes of both sides of the continent, or through, or with inter- 
mediate tribes, become a factor which has to be duly weighed 
and considered, the importance of which is only equaled by its. 
complexity. 
It is highly probable that an examination of the shell orna- 
ments mentioned by Mr. Barber by some competent conchologist 
familiar with West American shells and with the ethnological 
material of the California mounds would authenticate the species 
of which Mr. Barber’s shell ornaments are made, and it is to be 
hoped that he will have them carefully examined, and state not 
only the species but the authority for their determination. By 
doing so he will add much to the value of his researches, and the 
object of this criticism will be accomplished. ; 
THE LONG-JAWED GOBY. 
BY W. N. LOCKINGTON. _ 
fb somewhat inelegant title I have given to this curious little 
fish cannot be said to be its vernacular name, since, like the 
greater portion of the creatures that inhabit the world, it has not 
as yet acquired a commonly received name in our language, and 
the only name it has a perfect right to is the Latin one bestowed 
by its first describer, Dr. J. G. Cooper, namely, Gillichthys m- 
rabilis. 
1 Similar beads are found in the California mounds, and are simple concavo- 
convex disks cut out of the body whorl of O. biplicata.
