Two specimens of this species were obtained by us at Waadda Island ; 

 a third was seen, but it escaped us. It inhabits piles of shingle and 

 small bowlders near the mark of lowest tides, and when disturbed makes 

 its way downward with great celerity through small crevices into the 

 water. The specimens taken are each about 5| inches in length.
