THE ECHINOIDEA. 



II 



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. Xtll 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 pedicellariîE 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. ot 

 course, only a lapsus calami for Temnocidaris.
