Encope californica Verrill 1870
Family: Mellitidae	Order: Clypeasteroida
Locality: off Punta Arena, Bahia de los Angeles, Baja California, Mexico, 5 m, Jan. 2005	Dimensions: 115 x 115 x 15 mm

Following the remarks of Heinke Schultz in her book „Sea urchins“, page 349, the highest point should
be just anterior to the anal lunule. The anal lunule should extent a short distance between the distal ends
of the posterior pair of petals.

For Encope borealis the anal lunule should be beyond the distal ends of the posterior petals and the
highest point should be in the center of the flattened plateau.

Although this specimen came to me as E. californica I have some doubt, if it is rather E. borealis.
