170 TELLINA. 



other produced, and inflected ; a ridge in one valve, runs 

 from the apex to the anterior margin ; in the other valve 

 a sulcus; fine longitudinal striae cover the surface of the 

 shell; the margins very obtuse. The inside is a fine rose 

 colour; the muscular depressions very strong ; the hinge 

 has a single primary tooth in each valve, one of which is 

 notched : there is a small approximate lateral tooth in 

 one valve, but none in the other. Length two inches 

 and a quarter, breadth three inches and three quarters. 



Inhabits Madagascar. 



We are indebted for the knowledge of this species, to 

 Dr. Lister, who has given a good figure of the shell, with 

 the following note. " This large Tetten is of a corne- 

 lian colour, very smooth, and very thick and ponderous, 

 in those of this growth and bigness, but the lesser are 

 thin and light, and prettily fasciated, at least some of 

 them." It is a rare shell.
