plates, may also be added as differential characters of primary importance ; and further, 
as a secondary character, the disposition of the pedicellariz is worthy of attention. 
The intermediate character of Odinia, from a morphological point of view, between 
Labidiaster on the one hand and Brisinga and Freyella on the other, is striking and 
highly remarkable. 
The species of Odinia described by Perrier were all dredged off the coast of Morocco. 
The species now described from the Faerée Channel appears to have been confounded by 
Sir Wyville Thomson with Brisinga coronata, and was one of the first deep-sea novelties 
dredged by the ‘‘ Lightning” in 1868.

Rays very elongate and comparatively robust for the family, narrow at the base, but 
swelling gradually and quickly into a large ovarial inflation, the tumidity of which is 
greater abactinally than laterally, and tapers off rather abruptly, terminating at about 48
