NATURAL HISTORY OF VICTORIA. 



l^Annelida, 



in size. These capsules are greenish and translucent when fresh, 

 but soon become dark-brown and hard in spirit. 

 A specimen of the 





thickness of that in the 

 plate fl-ill stretch itself 

 along the ground to a 

 length of 6 feet in its 

 exertions to escape, 

 and one of that thick- 

 ness held up measured 

 5 feet 10 inches. As 

 has been observed of 

 the Pericliceta, the two 

 ends remain alive and 

 \agorous in moA'ement 

 long after some inches

 pores being the breathing spiracles (these sliould not appear on the anterior darls-colorcd rings 

 in front of the clitellaj). Fig. la, head of same specimen, contracted ; close to the nnmber and 

 letter the three clitellar thickenings may be seen ; natural size. Fig. \b, anterior end view, 

 sho^ving the mouth, magnified to twice the natural size Fig. Ic, anal teiminatiou, magnified 

 twice the natural size. Fig. Irf, the three clitell.w swellings when extended, natural size (the 

 three slight depressions often seen in each are too strongly marked. Fig. le, same when con- 

 tracted (the pit-like marks too distinct). Fig. \f, dorsal view of smooth space along the back, 

 with the median rows of transversely oval breathing pores on the anterior edge of the rings.
