One specimen, probably fossil, belonging to the carinate divi- 

 sion. There are two distinct forms commonly referred to L. quad- 

 rata ; one, with rounded edges, the other with a carinate margin. 

 The two forms serve to bridge the interval separating L. laevigata 

 from L. marginata.

The large wild-growing variety of L. squamosa originally de- 

 scribed by Aleock under the name Entosolenia Montagui occurs at 

 Selsey occasionally, as elsewhere whenever the type is abundant. 

 We figure a specimen, however, which is rather noticeable owing 

 to the fact that it combines the typical reticulate areolations with 

 irregular costse. 



The specific name Montagui* has recently been employed by 

 Silvestri for spherical ento-ecto-solenian varieties of L. hexagona 

 (Williamson sp.). The emplo} r ment of a specific name which has 

 already been allocated to a distinctive variety of a closely allied 

 species seems to us likely to tend to confusion, and is greatly to be 

 deplored.
