LORQUINIA

As shown by the above list, the fossil chitons of the Santa Mon- 
ica deposits belonged to about the same species as those of the present 
day. There were apparently, however, many more specimens belong- 
ing to the genus Callistochiton than we now find in shore collecting, 
although their habit of living in crevices in the rocks at extreme low 
tide suggests that they may be more plentiful beyond the collector's 
reach.
