The anterior claspers can each be retracted into a sht-hke 

 pouch which is placed transversely to the animal's axis (con- 

 trast Callorhynchus, where it is longitudinal); thus, in figure 3, 

 the clasper on the (observer's) left is partly protruded, while that 

 on the right is completely withdrawn. A reference to figure 6

Fig. 5 Chimaera nionstrosa, a transverse section of the longitudinal body 

 (haemalum-eosin). Ep., epithelium of the longitudinal body, a single cell 

 of which is shown highly magnified in the inset A; Cart., cartilage; M., muscle; 

 Ep. Cav., epithelium of the cavity. 



shows that the pouch is fined with stratified epithefium, im- 

 mediately below which are fibrous connective tissue and the 

 striped muscle bands of the derma, and that a few goblet-cells 

 are present. 



In the channel, however, formed by the continuity of the base 

 of the pouch and the anterior clasper, numerous goblet-cells are 

 found as indicated in figure 7, G. C. Goblet-cells are also present
