NOTES ON AUSTRALASIAN SHIPWORMS, 



revei'se it bears a blunt point. In this respect it recalls the 

 "Jedburgh Axe," a weapon of ancient Scottish warfare. The 

 stalks of the palettes are embedded in the muscles of the anterior 

 trunk, one on each side, close to the base of the conjoined siphons. 

 The sketch (fig. 6) shows the mantle-cup ripped open and one 

 palette removed and the other in situ. 'Fragments of the tube 

 before me show no choke of imbricating plates. A piece of 

 eucalypt timber, a foot in length, is riddled with numerous, close, 

 fairly straight burrows, 12 mm. in diameter, lined by thick shelly 

 tubes.

The study of the foregoing novelty induced a review of the 

 information amassed since the publication of my previous article 

 on the subject of Australasian shipworms. Mr. Gerald Halligan 

 has kindly placed at my disposal complete specimens of shipworms 

 found boring wharf piles in Circular Quay and Woolloomooloo 

 Wharf, Sydney. Among these I observe, 



Calobates saulii, Wright.

 ing in pectinate jaws the following joint.
