on the folds, and three or four between them. The 

 branchial tubercle is loop-formed with the extremi- 

 ties turned inwards. The oral tentacles, which are 

 numerous, are flattened from back to front. 



The alimentary canal forms a simple loop which 

 extends half way up the pallial sac ; the stomach is 

 elongated and a little widened, and has the liver (fig. 

 55, p. 88) overlying the left side ; the latter organ is 

 divided into several lobules which are composed of 

 short, tubular, slightly -branched processes. 



The reproductive organs (PL XXXII, figs. 4 and 5, 

 and fig. 54 in text) are two elongated masses each 

 composed of a double series of rounded or oval lobes 

 arranged in close order along the excretory ducts, 

 which extend as a compound tube a little in front of 

 the organ, and terminate in two nipple-formed orifices 

 in the vicinity of the anus.
