NOTE ON “THE -LIASSIC DENTALITDAS 
BY 
L. RICHARDSON 
During the construction of the new railway-line between 
Cheltenham and Honeybourne, a large number of fossils 
were obtained by the writer and Mr E. T. Paris. Their 
identification will require some time, as there are many 
new species. The Dentaliidz, however, have been dealt 
with," and it was thought: desirable to subject all the 
species from the Lias to a revision. The investigation re- 
sulted in a detailed description of the known species, and 
the giving of names to eight new ones, two of which, 
however, had previously received MS. names.

Unfortunately, the specific name of “acutum” was pre- 
occupied by a Dentalium “de YOligocéne Stampien,” so 
Mons. M. Cossmann proposed the name “LD. Azchardsonz”
