posterior end of body, distinctly narrowed. There is only one sort 

 of rods in the body-wall (Fig. 37. 3). They are irregularly shaped, 

 usually curved and C-shaped. The rods in the digits (Fig. 37. 2) are 

 not different from those in the tentacle-stem. They are rather large 

 and straight or slightly bent. Their outline is usually quite smooth, 

 and their ends are enlarged and perforated. 



This species is characterized by the shape of the calcareous ring, 

 the anchor-plates and the tentacle-rods; and it may by these charac- 

 ters be easily distinguished from the other Australian species of 

 the genus. 



Leptosynapta jacksonia n. sp. 



Port Jackson. 3. X. 1914. Sand and gravel. 3 — 5 fms. 4 specimens. 

 Port Jackson. 3. III. 1915. 13 fragments. 



The fragments from 3. III. 1915 are in a very poor condition, 

 and they are only with some hesitation referred to this species,

from which they differ somewhat in the colour. The specimens 

 from 8. X. 1914 measure up to 7 cm in length. Their colour is 

 bright yellow. They have twelve tentacles, each with 6 — 7 pairs
