VENUS transversa. 
TAB. CCCCXX1I. —fig. 1. 
Spec. Char. Transversely ovate, elongated, 
gibbose, nearly smooth ; posterior side 
small, rather pointed ; shell thin. 
The transversely elongated form of this Venus, (Cy- 
therea of Lamarck) distinguishes it well from the several 
varieties of V. incrassata (tah. 155.) found at Barton and 
upon the Isle of Wight; in shape it is between Cythereee 
nitidula and bevigata 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 Cliff by Miss Beminster. 
VENUS lineolata. 
TAB. CCCCXXIL— fig. 2. 
Spec. Char. Obovate, gibbose, marked with 
numerous, minute, transverse striae. 
Syn. Venus rotundata, JBrander, Jig. 91. excl: 
Syn. and Jig . 93. 
A. neat little shell, the strise 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 Linneus, 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 Tellina ambigua (tab. 403.) to which it is more nearly 
related. 
Presented by the Rev. T. Cooke, who found it sparingly 
at Barton.
