SOLEN. 131 



INFLECTED RAZOR. 

 PL 32. /. 1, 2. Dr. Coombe. 



18. Solen inflexus. S. testa ovato oblonga, utrinque hiante, margine 

 subarcuata ; cardine altero bidentato, costa transversali prominente. 



Shell oblong-oval, gaping at both ends, margin somewhat arched ; hinge 

 with two teeth in one valve, transversal rib prominent. 



This species, which does not appear to have been 

 hitherto described, is of a whitish colour, finely striated 

 concentrically, and, when recent, covered with an 

 orange-brown epidermis. The margin is plain and 

 inflected, and the valves, when closed, touch only at 

 two points, the inflected part, and the hinge. There is 

 a very faint depression running obliquely from the apex 

 of the shell to the margin, the impression of which is 

 visible within. The inside is white ; the hinge has two 

 teeth in one valve, and one in the other. The trans- 

 versal rib is not flattened, as in some of the preceding 

 species, but prominent and well defined. 



The specimen is in the possession of Dr. Coombe, but 

 its country is unknown.
