THE ECHINOIDEA. 
1 1 
duct is developed, going in the opposite direction, ending in the pore situated in 
the middle of the interambulacrum. As this new duct is rather short, it can only 
be seen on cutting most of the genital gland away; in the figure (PI. XIII Fig. 3) 
only the upper part on the left side of the gland has been left. The specimen 
opened is a male.

* PI. XXIV, Fig. 10 cited by Agassiz as belonging to this species is stated in the explanation of the 
plate to belong to Phyllacanthus dubia; it represents a valve of a tridentate pedicellaria, and since tri- 
dentate pedicellariæ are not found in A. canaliculata , it is probably the explanation which gives the correct 
statement. 
** In a note Agassiz here states to have originally placed it in the genus Temnechinus. This is, of 
course, only a lapsus calami for Temnocidaris.
