Janjukian series. Some of the forms, howevt-i-, noaitst the little 

 variety lucens, MacGillivray,! with the pt)lished dorsal surfatf have 

 a distinct spiral arrangement of the zooecia viewed from the loMer 

 or ventral aspect of the zoarinm. Another feature invariably accom- 

 panying this varietal charactrr, and which is sometimes met with in 

 other species of the genus, is the inclusion of a little glauconite pebble 

 in the centre of the zoarium on its lower side. This probably formed 

 a point of attachment for the initial zooecium.

Ohservdtions. — Four typical examples of this species were found 



in a sample from Bore 5, at 175-189 feet. They form an enciusting 



layer upon a species of Cellepora. 



The species appears to liave l:>een liitherto confined to the locality 

 of Baiinsdale.

 Observat lorix. — The usual form of the zoarium in these deposits 

 (polyzoal rock) is the lobed, bilaminate variation. In eonnection 

 with this it is interesting to note that MacGillivray (loc. sujMa cit. ) 

 says, " The lobate form is that usually found reeent. while the great 

 majority of the fossil specimens are cylindrical."
