The specimen upon which the abovedescription is based is in the WoodwardianMuseum ; it is very much larger than anyspecimen figured by Hall as belonging tothe species ilicifolius ; in fact, it resemblesmost closely those figures which are en-larged 3 diameters. I have thereforedesignated it as a variety of Halls species,and given it the name grandis to denote [Nat. size.] its unusual size. Locality.—North-east of Sleet How, 494- MIS^ G. L.

There are several specimens referable to this specie^?, both inMr, Postlethwaites collection and in the Woodwardian Museum. It is characterized by its small size, and the great number ofthecse in a given unit of length. These number between thirty-six and forty to the inch (fourteen to sixteen in 10 mm.). Noneof the specimens are as much as ^ inch (12-7 mm.) in length;they appear to be commonly yV inch (10*5 mm.) long, and have amaximum width of 4- inch (5*078 mm.), which is attained near thedistal extremity of the rhabdosoma. All the thecoe are curved, though the curvature is less in themiddle than at the proximal and distal extremities of the rhabdosoma.
