VENUS transversa. 



TAB. CCCCXXII.— >V. 1. 



Spec. Char. Transversely ovate, elongated, 

 gibbose, nearly smooth ; posterior side 

 small, rather pointed ; shell thin. 



JL HE transversely elongated form of this Venus, (Cy- 

 therea of Lamarck) distinguishes it well from the several 

 varieties of V, incrassata (tab. 155.) found at Barton and 

 upon the Isle of Wight ; in shape it is between Cythereoe 

 nitidula and laevigata of Lamarck; it is rougher than 

 either of them ; its thin shell is strongly marked by lines 

 of growth ; the lunette is large, ovate and pointed. 

 Found in the Barton ClifFby Miss Beminster. 



VENUS lineolata. 

 TAB. CCCCXXIL— /^r. 2. 



Spec. Char. Obovate, gibbose, marked with 

 numerous, minute, transverse striae. 



Syn. Venus rotundata, Brandcr, Jig. 91. excl. 

 Sy7i. and Jig. 93. 



A NEAT little shell, the striae are so fine as to require a 

 glass for their manifestation, but they are so deep that 

 they may be felt with the finger nail ; the lunette is of a 

 moderate size. 



This is not V. rotundata of Linnrus, but there is 

 hardly any doubt of its being Brander's fig. 91. his fig. 

 93 which Solander has referred to the same name, is 

 surely distinct : it has been mentioned in our description 

 of Telliua ambigua (tab. 403.) to which it is more nearly 

 related. 



Presented by the Rev. T. Cooke, wl;0 found it sparingly 

 at Barton.
