recurved dorsalwards. The externo-lateral ray is the thickest 
of the lateral rays, and is inclined slightly forwards and 
ventralwards, as also does the Jatero-ventralray. ‘The ventro- 
ventral ray is bent wholly in an arch directed forwards and

There are no prebursal papille. 
The spicules (fig. 4) are of a brown colour; they are large,

each has a dorsal branch which is bent slightly ventralwards. 
Each branch bears on its inner surface, about in its middle, 
a ventrally projecting spike-like process. 
The gubernaeulum (fig. 5, A and B) iscenspicuous, measuring 
about 140 w in length; posteriorly it is thickened into a knob 
20 w long by 10 w broad; anteriorly it tapers to a rounded 
point. On its dorsal surface it bears a keel; this is about 
14 ~ deep and extends for about half its length from the 
posterior end,
