OPHIOCNEMIS MOll. & Trosch. 



Miiller and Troscliel made a most singular mistake in examining the 

 original sjoecimen of Lamarck's Oph'mra 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 Amjihiura and Ojjkiothrix.

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

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