wider than in the Cribella oculata. They are bordered by 

 two sets of spines. The edge-row consists of transverse 

 ridges of long tapering spines placed two and three to- 

 gether. The spines projecting over the mouth are longer 

 and sharper. The madreporiform tubercle is very lateral, 

 and finely striate. It is surrounded by a border of short 

 spines similar to those on the spiniferous tubercles. The 

 eyelids are like those of the Eyed Cribella. 



Mr. Ball was the first contributor of this beautiful 

 species to the British Fauna. He obtained it many years 

 ago from the Nymph-bank off Waterford, and has two 

 specimens in his collection. When recent he says it was 

 of a bright orange colour. The specimen I have figured 

 I owe to the kindness of my friend, Mr. Philip Maclagan, 

 who was so fortunate as to add this species to the Fauna 

 of Scotland during the summer of 1839. He found it on 

 the coast of Ayrshire. It measures six inches and three- 

 fourths in diameter. The disk is nearly an inch broad, 

 and the rays above half an inch thick at their origins. 

 Muller was the original discoverer of the Cribella rosea. 

 He found it on the Norwegian coast, and figures it of a 

 bright rose colour. The Cribella oculata would appear also 

 to be found in the same region, and has been observed on 

 the coast of France. The genus extends its range to the 

 West Indies.
