This >j>ccies is allied to L. granoliratus Cpr., but that is more 



t .1. the central and lateral areas are more diverse in sculpture, 



and the concentric wrinkles are much stronger. In L. cancellnttt* 



the lateral areas are raised, which is not the case with the asellus. 



"Under the microscope this species can easily be separated from 



;i. iixirginatus Jeffr.) by external characters. In the 



nnon the scales are very minute, smooth, granular, reddish 



and closely appressed to the girdle; in the Leptochiton they are 



gravel like, irregularly crowded, larger, lengthened and striated. In 



I, also, the valves are more beaked, especially in young 



shells."

Shell oval, rather hw and regularly convex, not angulated d<>r-

 with an ill-dHim-d darker dorsal stripe.
