warts are all perforated, so that water contained in the body, as 

 well as the seminal filaments, are often ejected through them. 

 Mr. Cocks is convinced " that 

 the apertures on the body 

 have nothing anatomically to 

 recommend them to a notch 

 on the tubercular tally. They 

 are simple tubes with a trum- 

 pet-like base externally, pass- 

 ing between the muscular 

 fibres to the ovarian chambers 

 (Fig. 50), for the supply of 

 water and air in shallow pools, 

 or channels for the exit of the 

 ova. They form the points of 

 adhesion for all the stones, 

 shells, and sand, which cover 

 the body, and are, therefore, suctorial."

 a yellow, mixed with grey ash colour. The glands of the middle row 

 are white, the rest of the same colour with the stem. The feelers 

 are of a whitish colour, varied at the upper part with several cross 

 lines and brown spots of an irregular figure, like the backs of some 

 snakes." J^Uia.
