Genus Diphysa. 



D. singularis, De Blainville. ' Manuel/ p. 117, 1830. 



De Blainville founded this genus upon a specimen collected by Q,uoy and Gaimard ; but 

 his account of its structure is brief and insufficient to enable one to form an idea of the 

 real nature of the object. 



Genus Discolabe. 



Rhizophyza discoiclea, Quoy and Gaimard. 

 Discolabe Mediterranea, Eschscholz. 



Thus described by Quoy and Gaimard in the ' Annales des Sciences Naturelles/ t. x, 

 1827 : A little flattened disk, from whose circumference depend about a dozen slightly rose- 

 coloured appendages, consisting of little orbicular bodies connected with one another. In the 

 middle of the disc below there is a bundle of transversely striated suckers, whose base is 

 surrounded by little yellowish bodies. The middle of the upper part of the disc gives off a 

 very long tube, containing an air-bubble at its extremity, which is reddish. Length, an inch 

 and a half; diameter of the disc, five lines. Taken in the Straits of Gibraltar. Figured in 

 PI. V. B. Eschscholz, who based the genus Discolabe on this form, did not observe any 

 specimen of it himself.
