OPHIOCNEMIS. 



OPHIOCNEMIS Mull. & Trosch. 



Miiller and Troschel made a most sinojular mistake in examinino- the 

 original specimen of Lamarck's Ophlura marmorata, on which is 

 founded this genus. The specimen having shrunk in drying, a small 

 crack appeared between the arm-joints and the genital plate, and this 

 was taken for a second genital slit, lying beside the usual one. I had 

 an opportunity of closely examining this specimen in the Jardin des 

 Plantes. Nevertheless the genus is a good one, on other grounds, and 

 stands between Amjohiura and Ophiothrix.

The original, in the Jardin des Plantes, is stated to come from the 

 " Mers Australes," and was brought by Peron and Lesueur, in 1803.
