﻿EIGENMANN 



Sections through left and right eye-cavities of Lucifuga, specimen No. 76 (see plate 1 5C). 



These figures have same magnification as plate 1 6B (of head of one of her young) 

 with which they should be specially compared. Eye-cavities very large as compared 

 with those of the larva (plate I6B), while eyes are much smaller. X 60.
