ANATINA— Plate It. 



extremities reflected, posterior side rather com- 

 pressed, moderately gaping, extremities concentri- 

 cally wrinkled. 



Valenciennes, MS. in Mus. Cuming. 



Hab. Adelaide, South Australia (in sandy mud, at a depth 

 of ten fathoms). 



Younger specimens of this species in Mr. Cuming's 

 collection, show its characteristics better than the adult. 

 An apparently slight but important specific character con- 

 sists in the presence of a few faint, oblique, not concentric, 

 wrinkles near the umbo of each valve; and the species 

 inclines to be of a rather narrow cylindrically oblong form, 

 with the anterior extremities beaked in a rather confined 

 rotundately pouting manner. 



Rather more attenuated on the anterior side than usual, 

 which attenuation contrasts very perceptibly with the 

 somewhat globosely inflated posterior side.

 Anatina prismatica, Sowerby. 



Hab. New South Shetland, Antarctic Ocean ; Lieut. Ken- 

 dal, Dr. Eights. 



An interesting broadly truncated Panopaa-Vike species, 

 with a remarkably large anterior gape. The specimen from 

 which our figure is taken, was found on the beach at New 

 South Shetland after a gale of wind, by Dr. Eights of 

 Philadelphia, and described by Mr. Sowerby in the Pro- 

 ceedings of the Zoological Society for 1834. A specimen 

 had, however, been previously brought to England by 

 Captain King, to whom it had been presented by Lieu- 

 tenant Kendal, of H.M.S. Chanticleer, who found it in the 

 very same locality. This specimen, which is in the Bri- 

 tish Museum, was described by King and Broderip in the 

 Zoological Journal for 1830-31, and figured by Dr. Gray 

 in Griffith's Cuvier's Animal Kingdom, pi. xxii. f. 3.
